Human Practices

Integrated Human Practices


Our project does not exist in a vacuum but should instead be a part of the world. What can we learn from other people? What kind of impact can our project have in the world?


Getting Started

When our team met for the first time, it became clear very quickly that we all shared a common interest in medicine. We started to explore possible topics and agreed to show them together to our PI Heli Viskari and our advisor Yin Yin. During the first meetings, inspired by nature, we decided that we wanted to utilize bio-adhesives one way or another. We discussed mostly the applications that we could do, such as hydrogel patches for either diagnostics or drug delivery. Our project development started quite application-oriented and based on our own interests, but then the discussions changed heavily as we started to explore our possible model drug for the patches.

One day our team had a lively conversation about our findings regarding our topic ideation. At some point, a drug called doxorubicin surfaced in our discussion. As one person was elaborating on the severe side effects of the drug, everyone else went silent. This marks the turning point of our project. We discarded our initial progress and found our goal. We wanted to decrease the side effects that patients experience, and thus the development of our drug delivery system began.

While working on designing our system we also contacted Dr. Ayub to get more insights on how we can best learn to understand cancer and cancer treatments from a societal and human standpoint.

Reason for contact:

During our project ideation journey, we reached out to her to explore the feasibility of our concepts and gain insights from her expertise. With her extensive experience, we sought her feedback to assess the practicality of our initial ideas and later our project designs.

Key discussion points:

We presented our initial project ideas to Yin. She provided us with detailed feedback on their practicality and feasibility given our laboratory resources. She helped us evaluate the strengths and limitations of our concepts. We explored how to refine and optimize our ideas, and Yin shared insights from her own research to inform our approach which was crucial in helping us refine and narrow down our project scope.

Findings and implementations:

Yin introduced us to the phenomenon of Liquid-Liquid Phase separation (LLPS), a concept central to our project. Her research, particularly on LLPS formation using mussel foot protein and spider silk protein served as a major inspiration for our project. Beyond theoretical knowledge, Yin generously provided us with her plasmid backbone, her original plasmid construct containing mfp-1, adf-3, and SpyTag/SpyCatcher. She provided us several of her proteins enabling us to conduct preliminary experiments. Additionally, she gave her time, advice, and invaluable guidance, which helped us navigate the early stages of our project by focusing on the aspects that were both innovative and achievable.

Reason for contact:

Dr. Ayub is dedicated to establishing a research base for comprehensive cancer care in Bangladesh. Since choosing cancer drug delivery system as a topic of our project, we wanted to know how we can best learn to understand cancer and cancer treatment from a societal and human standpoint. Dr. Ayub leads initiatives to improve cancer awareness and research in Bangladesh. Because he is an expert in creating discussion between researchers, clinicians and patients, we reached out to him for advice.

Key discussion points:

After shortly discussing our project idea, our main discussion was around cancer awareness. Dr. Ayub thinks that spreading awareness is the responsibility of researchers. He pointed out that in Bangladesh there is a big barrier in communication between researchers and clinicians, since clinicians are often conservative and very busy.

Dr. Ayub works on improving cancer awareness and prevention in Bangladesh trough campaigns and tv. He recommends pamphlets, infographics and social media communication for spreading awareness. He sees lots of power in inviting experts, policy makers and patients to see eye to eye to connect on a more personal level.

Dr. Ayub sees that patients often feel powerless. Patients don’t have enough of information and the available information can be hard to understand. Therefore, patients feel that they are at the mercy of clinicians, but they are also ready to listen to anyone who has solutions to help. Dr. Ayub also points out that when a person is suffering, communicating with them can be challenging. He thinks that patients need empathy and open discussion that is also adapted to their educational background.

Findings and implementations:

Dr. Ayub was the first researcher working with cancer that we presented our project to and therefore having his approval and interest towards our project was very meaningful to us. He is passionate about spreading cancer awareness and hearing about his work and ideas inspired our own community outreach and awareness work. Soon after this meeting we started to work on designing surveys to learn from experiences of patients and the public.

Understanding the problem

It is often said that if a medicine has no side effects, it's unlikely to work [1]. There are many excellent drugs on the market, but the challenge with most of them is that they target the whole body to access the cells they are supposed to treat. The goal of drug development is to produce a comprehensively safe and effective medicine that improves patient outcomes and quality of life.

Some of the most serious side effect causing drugs are chemotherapeutic drugs. They are used to stop the growth of cancer cells, either by killing them completely or by preventing them from dividing. The problem with cytostatic drugs, as with many other drugs, is precisely their widespread exposure of cells in the body. This can cause different side effects in patients. These symptoms significantly reduce the quality of life, which is opposite of what is desired from a good treatment.

Working on a drug delivery system with the potential to decrease these side effects, we wanted to know more about patients’ experience with side effects. Therefore, we conducted two surveys for cancer patients and people without cancer diagnosis. Most importantly, we came to broaden and deepen our understanding of cancer’s effect on patients’ and loved ones’ lives.

Association of Cancer Patients in Finland, is a non-profit organization, established with patients in 1971, supporting cancer patients and their families. They function as a trustworthy information source and provide a platform for peer-support and patient networks. They look out for the interest of cancer patients ensuring that cancer patients are heard in society, for example by being involved in HTA processes and establishing the national cancer strategy. We reached out to them to better understand cancer in the big picture.

Establishing Collaboration

We had a meeting with Jenni Tamminen-Sirkiä (Executive Director, PhD) and Emmi Toivonen (Communications & NGO Specialist). We presented our project idea shortly and discussed topics such as chemotherapy side effects. In this meeting we established a collaboration for our survey, because in the association they have experience with conducting surveys related to cancer. They also provided us with some interesting statistics and helped us reach out to other cancer associations. Later they provided us with invaluable feedback on our survey designs, which we used to finalize our surveys. The association functioned as one of the main distribution channels for our patient survey.

Diving Deep

After the closing of our surveys, we met again with Jenni Tamminen-Sirkiä, to discuss topics around cancer and cancer treatment. We also discussed the main results of our surveys with her, and in our survey result analysis we have included many comments from her. We were very pleased to discuss with her as she has an immense amount of knowledge and perspective having worked both on cancer research and cancer associations in her career.

We talked about lots of different things related to cancer and cancer treatments, but here is a snippet of what was discussed and what we learned:

Every third person in Finland will get cancer. Cancer’s prevalence increases, especially due to aging population in Finland, and the same time we must work with limited resources. Cancer medicine is a fast-developing field. As more advanced treatments are developed, we must also think about who benefits from them? For example, the same treatment is not always suitable for all ages. With new therapies, we should have better systems to follow up the patients and their quality of survival. New is not always better, and with more targeted approaches we have to also ensure that efficiency is not decreased.

Side effects are the biggest hindering factor on adherence to therapy. Patients can have a wide range of side effects, and especially long-term side effects negatively affect patients’ quality of life. Peripheral neuropathy can be caused by platinum-based agents. One loses the nerve endings in their feet or fingers, leading to numbness and change in feeling. Chemotherapy can also affect autonomous nervous system, leading to changes in bowel movement or sweating.

Mental health is also affected by cancer. It never asks if it’s okay time to come, it will come when it comes even if you have other things going on in your life. Being ill also affects people’s normal roles, at work and home, which can make people feel useless. But many patients do adapt and make the best of their situation. People suffering from chronic cancer tend to find small things to enjoy, like the birds singing, and to stay motivated by focusing on good things.

What motivates people to stick to treatment despite the side effects, is knowing the facts of how the treatment will benefit them and how long they must go through the treatment. Accessible and easy to understand information is the key, and cancer associations play an important role in offering it. While in social media there is also misinformation about topics, it is good to have more access to information than less.

It is important that everyone knows common symptoms of cancer, so they can seek help in time. But people should also not over-monitor themselves. It’s a balance of worrying too much and not worrying at all. Young people should not worry too much, they should enjoy life. People should also know that a cancer diagnosis is not a death sentence. There are different types of cancers, and usually people can live quite good lives with new treatments.

Many people have trouble being around a person who is severely ill. Jenni Tamminen-Sirkiä reminds us, that if someone says that it’s easy and always comfortable, they are probably lying. It is not easy and not always comfortable; but it can be very rewarding.

To better understand people’s experiences and opinions about cancer and cancer treatments we conducted two surveys using Webropol. First survey was for people who are diagnosed with cancer (later referred to as the patient survey), and the second was intended for people without cancer (non-patient survey). The objective of the patient survey was to collect information and insights on cancer treatments and their side effects, on seeking information and communicating with healthcare professionals, and on the impact of cancer on different aspects of life. With the non-patient survey, we wanted to learn what people knew about cancer and cancer treatments, and how people's views have been influenced by the experiences of a loved one or acquaintance with cancer.

One of the main topics of our survey was chemotherapy including chemotherapy side effects. Most people answering our patient survey (82.2%) had undergone chemotherapy. Of them 45.7% reported experiencing severe or very severe side effects. Almost half (46.5%) reported experiencing long-term side effects while a third (32.6%) reported not being sure.

Most common side effect was weakness with only 2.3% of respondents reporting no experience. The second common side effect was losing hair, which was also rated as the most severe side effect with 62.0% rating it as very severe. A paper published in 2023, looking into patient-reported side effect of chemotherapy, reports fatigue as the most common side effect (87.0%) followed by loss of appetite (71.4%) and diarrhoea (49.4%) [2]. In our patient survey loss of appetite was experienced by 83.7% and diarrhoea by 67.4%, numbers even higher than those reported in the paper.

On top of the side-effects that we asked about in the survey, patients reported a wide range of different side effects including fever, insomnia, nail and skin problems, infection due to weakened immune system, weight loss or gain, hormonal problems, changes in body temperature, changes in sense of taste, weakened eyesight and hearing, sexual reluctance, early menopause and infertility. In conclusion, our results show that people experience a wide range of different side effects.

We also learned how chemotherapy side effect affect people’s life. Especially long-term side effects have a big impact on people’s life. Since there are lots of different side effects, they can also affect patients’ life in many ways. We learned that many side effects such as change in gut function, weakened immune system and lack of energy affect people’s social life. Cognitive changes and general lack of energy are symptoms that affect patient’s ability to work or study. One of the often-reported long-term side effects, neuropathy, is a symptom that affects people's ability to move, causing problems in hobbies such as sports or crafts and in work that requires movement.

In this summary we looked especially at the topic of chemotherapy side effects, but with our surveys we investigated a wide range of topics. You can find our full analysis and reflection on the survey results from the Survey page.

Developing a Solution

One way to prevent side effects is by developing a more targeted drug delivery system. This is what we are trying to achieve in our project. We aim to create a solution that not only effectively delivers therapeutic agents but also significantly reduces the adverse effects of treatment, ultimately enhancing the quality of life for patients battling cancer.

Throughout our project journey, we consulted with experts in various fields to seek guidance based on their experiences and expertise regarding the challenges we were facing. These consultations helped us refine our approach and ensure that our design could be effectively implemented. With the insights gained from these consultations, we explored various strategies for improving drug conjugation, optimizing protein modifications, testing Liquid-Liquid Phase Separation (LLPS) formation, and ensuring the stability and effectiveness of our system.

Associate Professor at University of Turku in the pharmacology and drug development. (Previously Academy Research professor at University of Helsinki, Faculty of Pharmacy in the division of Pharmacology and Pharmacotherapy)

Reason for Contact

In our project we identified a problem related to the effective conjugation of doxorubicin (Dox) in our drug delivery system. To address this, we contacted Virpi Talman who is an expert in cardiovascular pharmacology and drug discovery. She has experience in working with doxorubicin [3]. We sought her expertise due to her extensive knowledge in the field and her experience with doxorubicin, hoping to gain insights into potential conjugation strategies.

Key Discussion Points

Our discussion revolved around potential ways to conjugate dox in our drug delivery system. She gave us contacts of other people who are experienced in the field. She explained how drug kinetics was a later stage, and her experience would be more useful when we wanted to test our system and see if post-conjugation, the functionality of doxorubicin would be effective in killing cancer cells. Drug kinetics and functionality were for later. We first needed to focus on finding a way to effectively conjugate our Dox.

Findings and Implementation

We realized that for using Dox in our system, we needed someone more experienced in protein chemistry since they would be able to better guide us on efficient conjugation. Our system requires a chemist rather than a pharmacology expert at the moment. As a result, we redirected our search towards experts in protein chemistry. This adjustment was necessary to build a solid foundation in the basic chemistry involved in our project before delving into pharmacological aspects of drug kinetics and functionality.

Alba Sanz Velasco, a doctoral researcher in the Biohybrid Materials research group at Aalto University

Reason for Contact

We needed expert advice on protein chemistry, purification, separation and yield for our drug delivery system. Therefore, we contacted Alba Sanz Velasco, who has extensive expertise in chemical and pharmaceutical industry.

Key Discussion Points

Our discussion focused on addressing our main concerns regarding the purification of our conjugated Dox with the drug component. She provided valuable insights, shared her expertise, and offered opinions on the various scenarios we had in mind. We also discussed the best methods for solubilizing powdered Doxorubicin, considering options like DMSO and water.

Furthermore, we explored ways to maximize the efficient transformation considering our recombinant proteins are quite big. Alba was impressed and interested in our project, and she agreed to be our advisor to follow our progress and support our efforts. She also offered to assist us with mass spectrometry, which we will need to verify the successful conjugation of doxorubicin and determine the conjugation ratios.

Findings and Implementation

Based on the discussions with Alba, we learned that instead of trying to conjugate the dox with our recombinant protein, we could utilize an intermediate. Initially, we had disregarded an intermediate approach because we thought conjugating dox with the linker, and then purifying it would be very difficult since the MW changes would not be significant. However, Alba suggested that we conjugate the linker with our CGG repeats & then separate that using dialysis (cheapest and most efficient way we could utilize given our budget & time); after which we conjugate the dox to the now linker attached protein and further use dialysis to purify it. The biggest help was in the form of the dialysis solution. She cleared up our doubts regarding it and even gave us a clear method in which we could use it to purify the needed proteins. Based on Alba’s advice, we integrated the idea of dialysis for purification in our experimental plans. We started placing orders for the necessary materials.

Alba played a key role in guiding us through our project journey. She helped us prepare the column for FPLC, provided essential advice for setting up the dialysis system, and supplied us with the membrane needed for the dialysis process. Additionally, when we encountered issues with ineffective lysis, she offered invaluable guidance that helped us improve our approach. Throughout our journey, Alba’s support has been instrumental in helping us navigate these complex procedures and ensuring our experiments progressed smoothly.

Dr. Shiqi Wang is the principal investigator of the Intracellular Drug Delivery Research Group at University of Helsinki working with development of novel drug delivery systems.

Reason for Contact

We contacted Dr. Shiqi Wang to seek her expertise in nanoparticle-assisted drug delivery systems to guide us in the design and development of our own novel drug delivery system. Given that this was our first time working on such a system, we wanted an expert to guide us with the specificities and foundational principles necessary for the successful creation of a drug delivery system. Dr. Wang’s extensive experience in the field made her an ideal expert to consult for guidelines on designing an effective drug delivery system.

Key Discussion Points

During our meeting, we presented our project to Dr. Wang, who showed great interest and asked critical questions that prompted us to re-evaluate certain aspects of our approach. For example, she asked us about whether our drug would be in the continuous or dispersed phase of the LLPS. Making this choice would be critical in determining both the stability of our system and the release of our drug.

Further, we discussed several ways to achieve specific conjugation of our drug. She gave us a couple of ideas; she mentioned one way in which we could do the labelling is by feeding the bacteria a non-canonical amino acid allowing us to use that as a specific binding. We also discussed the possible ways we could visualize our LLPS once it was formed. Further, we discussed possible dosage amounts, how large of a concentration we would require etc.

Following our initial meeting, we had a second follow-up meeting with Dr. Wang, where we updated her on our progress and discussed the design, including the intein sequences we had incorporated. Our primary focus during this meeting was to refine our conjugation approach, particularly regarding the concentration of Doxorubicin needed for optimal results. Dr. Wang inquired about the linker we were using and advised us to prepare a 10mg/ml stock solution of Doxorubicin, suggesting that we avoid going below this concentration to prevent wastage, given the limited supply we had. Furthermore, she recommended using twice the amount of linker during the conjugation process to enhance efficiency. This meeting was crucial in determining the necessary stock solution and protein quantities required to ensure successful conjugation in our experiments.

Findings and Implementation

Dr. Wang’s insights led us to several important realizations. For visualization of our LLPS, we learned that Doxorubicin is fluorescent, and we could utilize this. Further, the hydrophobicity of Doxorubicin might help us with LLPS formation but there is a chance that our Doxorubicin could get buried in the core of LLPS, potentially impacting drug release. We learned that no chemical method would be site-specific. We might need to consider for DNA sequence modification. Specificity would mean a compromise with concentration. If we keep it non-specific, we would be able to conjugate larger amounts of Dox and based on Wang’s experience with Doxorubicin, to achieve maximal potency, larger concentrations would be needed. Therefore, we would have to find a balance between specificity and concentration.

Based on our discussion, we realized if we wanted to achieve a specific conjugation to be able to precisely control the dosage of Dox, we would need to change our approach and focus on a gene sequence modification rather than on chemical conjugation methods.

Dr. Yu Zhou is a Postdoctoral researcher in Biohybrid materials research group, school of chemical engineering at Aalto university. He has worked on developing protein based optical force sensors. Currently he is working on developing methods to combine protein cages and other synthetic materials for novel catalysis applications. At the same time, he is an expert in protein chemistry, which the field is correlated with out iGEM project and experiment.

Reason for Contact

We reached out to Yu Zhou because of his expertise in protein chemistry. Our project involves protein modifications and testing Liquid-Liquid Phase Separation (LLPS), so we sought his guidance to ensure the feasibility and success of our experiments. Specifically, we faced some challenges with expression promoters and preventing undesired chemical reactions and contacted him to gain insights from his knowledge and expertise in these areas.

Key Discussion Points

During the meeting it was discussed that despite the feasibility of project, some reagents are required to ensure the success of our experiments. One aspect would be the promoter of the expression. Since we are using T7 promoter, which he identified as the strongest one for bacterial expression, Zhou recommended having a backup design. One prominent example would be the Arabinose promoter.

Additionally, our modification to Yin's original design has significantly altered the protein’s characteristics. As such, it would be important to test whether Liquid-Liquid phase separation (LLPS) still occurs in the presence of doxorubicin. One potential solution he suggested was conjugating the existing unmodified spider silk and combining it with mussel foot protein.

Furthermore, Zhou advised us that to prevent the undesired disulfide bond formation from CfaC-CGG8 expression (containing 8 free cysteine residues), we should add TCEP as reducing reagent to the resuspension.

Findings and Implementation

Following the discussion, we implemented several key recommendations. To ensure time efficiency in case a backup is required, we ordered second promoter. Additionally, we conducted experiments to test whether LLPS formation occurs using unmodified spider silk conjugated with Doxorubicin and mussel foot protein in the presence of additional hydrophobic molecule. The experiment was successful, and we observed LLPS formation. To address the issue of undesired disulfide bond, TCEP order was added to our reagent list from ThermoFisher.

Dr. Michael Jeltsch is an Associate Professor in Division of Pharmaceutical Biosciences at University of Helsinki, and PI of Lymphangiogenesis Research and Antibody Development. He has worked with protein chemistry and biomedicine for instance and has an extensive background in protein purification.

Reason for Contact

We initially contacted Michael to get training for FPLC at the Faculty of Pharmacy (University of Helsinki), since the FPLC equipment at Aalto University was temporarily broken and our team members knew he had a lot of expertise in protein purification.

Key Discussion Points

When contacting Michael for the first time, we explained our project and overall, more about iGEM. The key point that we obtained from his guidance is that to lyse E. coli for protein purification, not all buffers can be used due to possible chemical modification at His-tag. As such, general protocol from Qiagen (The QIAexpressionist) is a good starting point.

After following general protocol from this handbook, he taught us how to properly use FPLC machine from Bio-rad brand. Since we are planning to pack our Ni-NTA resin to the column, he also showed us how to do it with our G-Trap 5 mL FPLC column and any precautionary that we need to consider while doing it. Finally, based on our discussion, he provided us with several solution for our SDS PAGE casting problem and taught us his technique to make SDS PAGE gel in a rapid manner and just with parafilm (no fancy securing, just placed on top of rubber stopper).

Findings and Implementation

We implemented all of his techniques for repacking the FPLC column many times after that and purifying our proteins. His teaching is still relevant even after changing FPLC machine to ÄKTA brand and there is no problem during the process.

Orion is a Finnish pharmaceutical company, which was found in 1917. Orion's Pharmaceutical Research and Development unit is an important link between drug discovery and commercial product development, ensuring drug safety and that the medicine works and is absorbed as intended.

Reason for Contact

We contacted Orion because we wanted an expert opinion regarding the big picture of cancer drug development, as they have experience covering the discovery phase along all the other phases from 1 to 4 (from target identification to lead optimization, candidate selection, and further). We also wanted their opinion on our project overall regarding what challenges we might face. Our request for information was shared internally at the company, and one of the experts replied to us.

Key Discussion Points

Bert Van Veer told us that he has been interested in nanoparticles and their potential in targeted drug delivery for a very long time. He has been following the research and clinical trials of different targeted therapies for the last 20 years, and therefore he was interested in our project. He provided us with many new thoughts regarding our project, wishing to help us evaluate the open research questions of our system. He recommended us to do a review of different nanotechnologies that have been tested clinically in the last decade, for example Bind BioSciences and Cristal Delivery. He also wondered on the long-term stability of our LLPS in human plasma.

Findings and Implementation

Regarding the review of different nanotechnologies that has been tested clinically, such as Bind BioScience and Cristal Therapeutics, unfortunately we didn't have time to do a proper review. Although we did search and take notes on the companies and their methods, therefore implemented discussions to our project development, for example regarding considerations of how our drug delivery system affects the properties of doxorubicin and other potential transported drugs, such as bioavailability and possible drug resistance. This made us consider our Future vision, which can be found below.

Our Future Vision

Our goal is to lay the groundwork for a flexible drug delivery system that can be modified to target different cell types and utilize different agents. In the future, it could be used in place of traditional chemotherapy for example, to reduce the side effects that patients experience. Although our end-users are the patients, it is good to remember that it is often the healthcare staff who make the treatment recommendations and the decision on the form of treatment. While we are going for a proof of concept, we want to take a look at the possible future of our project and consider variety of questions related to it.

Developing COALES

Developing a new drug delivery system requires funding and time, like developing a new drug from scratch, which is extremely time consuming and costly. Currently drug approval pipeline can take on average around 15 years. From around 5 000 – 10 000 compounds, only one new drug reaches the market (Figure 1). During this time, it has been estimated that approximately hundreds of millions of dollars will be spent and the costs can reach even over billions of dollars. [4] For example, the development of the first clinically approved nanomedicine, doxorubicin-loaded liposomes (Doxil®) took allegedly approximately 7.5 years [5] and was FDA-approved in 1995. It is good to keep in mind, that the basic research on liposomal doxorubicin began already in 1979, which is called “pre-doxil” era [6]. Because targeted drug therapy is considerably new field, it is hard to estimate the true length and costs to develop a new system especially in 2024 when technology is advancing at incredible speed.

Figure 1: Drug discovery and development pipeline. Adapted from [7]

Developing a drug and drug delivery system, requires different in vivo and in vitro testing by law. Currently these include for example animal testing and clinical trials on humans. Animal testing has always and still does raise questions about their necessity. The aim of animal models is to reproduce the diseases conditions found in human, but in most of the cases, they have very different cytochrome P450 activity (the most abundant drug metabolizing enzyme family in humans). Therefore, there is a large variation in drug metabolism between species with respect to both enzyme expression and activity profiles which is proved by research. Current models used cannot model the metabolism of a human, so therefore until better solutions are provided to explore the ADMET (administration, distribution, metabolism, excretion and toxicity) as a whole, animal tests will continue. [1]

There are still many different innovations being done. For example, in the future, what our team hopes is that instead of animal testing we would be able to prove the safety of our drug delivery system with different microfluidic models such as organ-on-a-chip. Of course, right now they also have their disadvantages, since mimicking complicated systems in an engineering way will not only always require more pumps, channels and other equipment, but also good amount of funds. [8]

During the development pipeline, questions regarding the possible drug’s properties, such as half-life, bioavailability and toxicity will be further assessed. It has been shown that in case of the first generation clinically approved nanomedicines, such as Doxil, significantly extended the circulation half-life, improved bioavailability and reduced the toxicity of the corresponding free drug. [9] We are expecting to see similar results with our drug delivery system.

What if our project succeeded and we started to use COALES in practice?

Let’s imagine a world where there was a functional COALES drug delivery system. Delivering cancer drugs with COALES means that patients don’t have to suffer major side effects. Traditional chemotherapy causes a wide variety of side effects, and some people suffer long-term effects for life, which can negatively affect their well-being, mental health, career, hobbies, and social life. With COALES, people’s life quality improves a lot. The downside is that COALES might not be available for everyone, and this creates a greater inequity among patients. Does COALES work for only certain cancer types and certain cancer drugs? Is COALES available everywhere? Do people have to pay a lot of money for it?

For patient safety, it should be ensured that the system is tested thoroughly with each different combination of cancer and agent and approved for usage before using the system on patients. This will likely take a lot of time during the first years and therefore create inequality in treatment between patients diagnosed with different cancer types. To optimize beneficial outcomes, we should aim to prioritize certain treatment combinations that on average cause more significant side effects.

When it comes to financial questions, our COALES system could be cheaper than the alternative, antibody drug conjugates, due to simpler manufacturing process that consumes less reagents for example. The true price difference, and therefore the true costs to produce COALES, should be estimated later when more accurate data has been obtained from our formation process. For example, then more accurate yield, formation time and raw material costs are available for the calculations regarding upscaling and downscaling.

Although developing a drug and drug delivery systems is costly, we believe that everyone should have equal opportunity to receive good cancer treatment regardless of their financial situation. Therefore, we would want to establish a non-profit organization to look out for the patients’ interest when it comes to treatment and finances. On top of fundraising for better treatment, the organization would work to raise cancer awareness regarding different cancer types for example, like in Pink Ribbon’s case. The promotion should be done together with the existing organizations, our organization acting more as a link between the existing ones to help both nationally and internationally. Also, one of our primary goals would be to raise awareness on how to prevent cancer, for example with your own life-style choices and how to recognize early symptoms of different cancers. While all cancer cannot be prevented by life-style choices, the ideal scenario is that our treatment would become less necessary as cancer incidence would decline.

What if someone misused our system?

Our goal to develop a highly adaptable system could also pose dangers. Could the system be misused by administering performance-enhancing drug in athletes to avoid detection? Could the system be used for other illegal means, like drug usage or bioterrorism? With our highly adaptable system there is also the risk of illegally replicated systems by unauthorized manufacturers, that could create dangerous situations especially in countries with less regulation on health care. To avoid misuse, our drug delivery system is initially intended to be highly regulated. It should only be handled by qualified medical personnel and not meant to be available for purchase by the public. By focusing on careful clinical testing, staff training, safety regulations and treatment availability, we can maximize the systems positive impact on patient care.

Introduction

To understand people’s experiences and opinions better about cancer, cancer treatments, and their side effects, we conducted two separate surveys. First survey was for people who were diagnosed with cancer (later referred to as the patient survey), and the second was intended for people without cancer (non-patient survey). The objective of the patient survey was to collect information and insights on cancer treatments and their side effects, on seeking information and communicating with healthcare professionals, and on the impact of cancer on different aspects of life. With the non-patient survey, we wanted to learn what people knew about cancer and cancer treatments, and how people's views have been influenced by the experiences of a loved one or acquaintance with cancer. Additionally, we wanted to compare the opinions between the patients and the non-patients. To address these topics, the surveys were divided into four parts: Part I – Demographic, Part II – Cancer knowledge and experiences, Part III – Communication and Information and Part IV – Social impact. Our surveys were available in both Finnish and English.

While creating these surveys, our team carefully took into consideration the ethical principles of research with human participants. First our team researched on our own about the ethics and what needs to be considered, and revised “The ethical principles of research with human participants and ethical review in the human sciences in Finland” -document provided by the Finnish National Board on Research Integrity TENK. [1] Based on this, we didn’t need an ethical review statement from a human sciences ethics committee. While making the surveys, we actively consulted Association of Cancer Patients in Finland. They also functioned as a main distribution channel for our patient survey among other cancer patient associations; Colores and Europa Donna Finland ry. After the surveys closed, we met with Association of Cancer Patients in Finland again and discussed the results, while ensuring that no laws such as General Data Protection Regulation (GDPR) was broken.

Part I - Demographic

For the patient survey, we received a total of 155 responses. Most of the respondents (95.5%) wrote their primary home country to be Finland. Majority (94.8%) of the respondents were female. The largest age group of respondents were 45–54-year-olds (28.4%), followed by the 55–64-year-olds (26.5%), 65–74-year-olds (21.3%) and 25–34-year-olds (11.0%). For the non-patient survey, we received 166 responses. Well over half (69.0%) of respondents wrote Finland as their primary home country followed by Indonesia (9.4%), Germany (3.5%) and USA (3.5%). Majority (65.7%) of respondents were female. The largest age group of respondents was 18–24-year-olds (47.6%), followed by 25–34-year-olds (31.3%), 35–44-year-olds (10.3%) and 55–64-year-olds (7.2%).

Compared with the demographic of the patient survey, the non-patients are younger and there is larger percentage of men and non-Finnish respondents. We discussed the high proportion of women who participated in the patient survey, with Jenni Tamminen-Sirkiä (the executive director of Association of Cancer Patients in Finland), and she also reported that women usually take more active part in the functions of the Association of Cancer Patients in Finland. Apparently, women seek peer support more than men, at least in the form of engaging with others in associations. [2] For the patient survey, we received more answers from people diagnosed recently (Figure 1). Around half (54.2%) of respondent were diagnosed with cancer between 2022 and 2024. Approximately one third (37.4%) of respondents were diagnosed between 2017 and 2021. The earliest year reported for cancer diagnosis was 1993.

Figure 1: Results to question for patients: “What year were you diagnosed?”

The fact that most respondents (94.8%) were women has had a significant impact on the responses to the survey. Thus, the more common types of cancer in women are more pronounced in the responses: Figure 2 shows that the most common type of cancer among respondents was breast cancer (46.7%), followed by colorectal cancer (10.6%), ovarian cancer (7.2%) and lung cancer (6.1%). Prostate cancer, which is common among men, does not appear in the results. However, other most common types of cancer for both sexes shown by for example the Finnish Cancer Registry’s Cancer 2022 statistical report, were lung and trachea cancer and colorectal cancer, which appear in the survey responses as common types of cancer. Globally, the most common type of cancer was tracheal and bronchus cancer and lung cancer, the second most common breast cancer and the third bowel cancer. [3,4]

Part II - Cancer Knowledge and Experience

Cancer Treatments

In terms of general knowledge about cancer and its treatments, we asked non-patients to evaluate their knowledge (Figure 3). Out of 166 respondents, 1.8% stated they do not know at all or almost at all anything about cancer, 37.3% knew a little, 44.6% said to have moderate knowledge, 13.9% said they know a lot, and 2.4% stated they know a lot and work in the field. These findings show that most respondents had at least a basic understanding about cancer and its treatments.

Figure 3. Results to question for non-patients: “How much do you think you know about cancer and its treatment?”

To find out whether for example, the prevalence of cancer treatment affects its awareness, we asked the non-patients what cancer treatments they had heard of while asking from the patients what cancer treatments they had received (Figure 4). The non-patients were the most familiar with chemotherapy (99.4%), surgery (93.4%), and radiation therapy (92.2%). Approximately half (51.8%) of the responders were familiar with immunotherapy and 41.0% with targeted therapy. Most of the patients (87.7%) told that they had undergone a surgery and 83.9% had received chemotherapy, 54.2% radiation therapy, 11.0% immunotherapy, and 9.7% specified targeted therapy. Three responders 1.9% were unsure about the treatments they had undergone. A significant number of patients, 72.3% (112 out of 155) reported receiving both surgery and chemotherapy, highlighting the common use of these two treatments in combination [2].

Figure 4. Results to questions: “What cancer treatments have you received?” (patients) and “Which cancer treatments have you heard of?” (non-patients)

Based on our results, the prevalence of cancer treatment doesn’t directly affect its awareness. We initially thought that the reason was maybe related to how long these treatments had been in place, but this turns out to not be fully true either. For example, chemotherapy has been given since 1949 and in combination for the first time in 1958. [5] On the other hand, immunotherapy is often perceived as relatively recent innovation, but the clinical results to treat tumors were first described in May 1893. However, the reason why the treatment was not adopted actively was the lack of a known action mechanism, among the risks of infecting patients with highly pathogenic bacteria. So, oncologists kept preferring surgery and radiotherapy. [6] Even though the first immunotherapy agent was approved by the US Food and Drug Administration (FDA) in 1986 [7], the first immunotherapy for cancer was approved in 2011 [8]. Since then, active research has been going on and as a result we can see that non-patients are quite aware of this treatment (51.8%), regardless of it not being used much yet (11.0% of the patients said to have received it).

When treating patients, an essential part of the treatment is to monitor the patient's ability to function during the treatment. We asked the patients how their treatment affected their physical activity levels compared to before starting the treatment. Specifically, half of the responders (49.7%) indicated that their physical activity decreased greatly, and 29.7% noted a decrease. In contrast, only 3.9% felt that their activity level greatly increased, while 5.8% said it increased, and 9.0% reported no effect at all. Three people out of 155 were unsure.

Figure 5. Results to question for patients: “How did your physical activity change during your cancer treatment compared to before you started it?”

These findings support that cancer treatments significantly impact physical activity, with many patients experiencing reduced levels of activity, likely due to treatment side effects. A study done in 2020 revealed that patients find it very difficult to engage in physical activity especially in public places, due to fear of overheating and infection, as well as insecurity due to hair loss. Physical activity has been shown to reduce side effects of the cancer treatment, by example increasing blood flow and therefore activating the sympathetic nervous system, so it really is a problem when side effects can drive people into these vicious cycles. [9]

Chemotherapy

Regarding chemotherapy, we asked the non-patients to evaluate their knowledge (Figure 6). A bit less than half 42.2% reported knowing a little and 41.6% had moderate knowledge. Only 10.8% said they knew a lot, and just one person indicated they were highly knowledgeable due to working in the field. This indicates that public awareness aligns well with the reality of cancer treatment, as chemotherapy remains one of the most widely used options for managing cancer. Chemotherapy is both the most known treatment (99.4%) and the second most frequently received treatment among patients (83.9%).

Figure 6. Results to question for non-patients: “How much do you know about chemotherapy?”

Most of the patients (82.2%) had undergone chemotherapy. The majority of the patients had received chemotherapy for the first time in recent years 2024–2021 (Figure 7), which corresponds well with the year of diagnosis (Figure 1). The open responses later in the survey strongly emphasized the duration of chemotherapy, which we didn’t take into consideration while creating the questions. A chemotherapy course (series of cycles) often takes 3 to 6 months. It is common to go through approximately 4 to 8 treatment cycles during that time. [10] This can affect the results of this question particularly, since we don’t unfortunately know for how long the patients have received chemotherapy and if they had to go through it again for another year.

Figure 7. Results to question for patients: “Which year did you receive chemotherapy for the first time?”

Overall, these results (Figure 7) reflect the ongoing incidence of cancer. One of the respondents said that they had received chemotherapy for the first time in 1995, which also illustrates the timelines in cancer treatment. It is good to keep in mind that the majority of those who have had cancer previous years and are older, (for example in case of breast cancer over 60% of the cases are found in women over 60–years-old [11]) don’t necessarily actively use internet as much, which also reflects to the absence of responders from earlier years. [2] Also, not everyone who has been cured stays active in cancer associations.

We then asked the patients about their expectations and thoughts of the efficacy of chemotherapy before and after the treatment (Figure 8). Before treatment, the majority, which was approximately half (49.6%) of the patients, expected chemotherapy to be effective while the rest thought it would be moderately (26.4%), extremely (18.6%) or mildly effective (8.5%). Nobody thought it would be not effective at all. After treatment, the opinions were more spread, but most opinions were now more on the positive side (extremely effective went up to 26.4%, and even thought effective decreased to 41.9%, moderately effective decreased also to 20.2% which insinuates positive outcome for the patients).

Figure 8. Results to questions for patients: “Before receiving chemotherapy, how effective did you expect the chemotherapy treatment to be?” and “After receiving chemotherapy, how effective would you rate it in treating your cancer?”

Overall, before and after treatment patients believed chemotherapy to be effective (both times approximately 68.3% ±0.1 considered chemotherapy to be effective or extremely effective). These results indicate that most of the patients felt that the treatment met their expectations. An issue regarding the readability of the data, is that Figure 8 doesn’t consider the individual changes in opinions. Therefore, we took the raw data and compared the change in individuals’ opinions separately, by creating a table, color coding the answers and writing down the changes for example from “effective to mildly” (Figure 9). After, we created a new table which counted the answers based on our conditions being the exact text (Table 1).

Figure 9. The raw data curation into readable data, based on the questions for patients: “Before receiving chemotherapy, how effective did you expect the chemotherapy treatment to be?” and “After receiving chemotherapy, how effective would you rate it in treating your cancer?”

Table 1. The results of did the patients’ opinions change regarding efficacy of chemotherapy before and after receiving it, and if not, how did they change. The bolded texts “Extremely, Effective” etc., state the percentage of answer being the same before and after chemotherapy. The plusses (+) and minuses (-) mark the positivity and negativity of the change. None of the opinions started from not effective at all, so therefore those rows have been left out from the table.

Half of the patients’ (50.4%) expectations were met with better and worse, since their opinions didn’t change after receiving chemotherapy (marked with bolded text in Table 1), and respectively the other half’s opinion changed, almost equally as much negatively (23.2%) and positively (26.4%). The opinions changed with 8.8% of the patients, from effective to extremely effective (positive change), effective to moderately effective (negative change) and in a roundabout way moderately efficient back to effective (positive change) with each. Overall, the data suggests that there is a significant degree of individual variation. Factors such as patient health, cancer type and what knowledge and expectancy is given by medical professionals before the chemotherapy, may influence these outcomes. Further research would be needed to understand also other factors contributing to the expectations regarding chemotherapy efficacy.

Additionally, to patients’ experience, we also asked the non-patients, how effective they believed chemotherapy to be in cancer treatment. A significant majority, 69.3%, rated it as somewhat effective, 15.7% said very effective and 13.8% considered it as slightly effective. However, a small percentage, 1.2%, believed it to not be effective at all. This reveals the majority believed in the effectiveness of treatment however, patient’s firsthand experiences lead to a wider range of opinions.

Chemotherapy and Side Effects

Regarding side effects of chemotherapy, we asked the patients how severe they expected them to be and how they turned out (Figure 10). A bit less than half (44.2%) expected severe side effects, 28.7% expected moderate side effects, 20.2% expected very severe side effects and 11.6% expected mild side effects. Therefore 64.3% of respondents expected severe or very severe side effects. It’s good to note that this survey was conducted after these respondents had already received chemotherapy and therefore their reported expectations might be skewed as they are not truly collected before their chemotherapy treatment.

After chemotherapy, the patients assessed the side effects to be moderate by 37.2%, severe by 29.4%, very severe by 16.3% and mild side effects by 16.3%. Therefore, 45.7% of respondents reported experiencing severe or very severe side effects. Compared with the expectations, people generally expected more severe side effects than what they experienced, which tells of how chemotherapy is perceived. Still, majority of people (82.9%) experienced moderate to very severe side effects.

Figure 10. The questions for patients: “Before receiving chemotherapy, what was you expectation of the side effects?” and “After receiving chemotherapy, how would you rate the severity of your side effects?”

We also asked people to rate the severity of different chemotherapy side-effect based on their experience from no experience – mild – moderate – severe – very severe (Figure 11). Based on the results the most common side effect is weakness with only 2.3% of respondents reporting no experience of this side effect. The second common side effect is losing hair, which was also rated as the most severe side effect with 62.0% respondents rating it as very severe. The least common side effect is vomiting with 63.6% reporting no experience and 22.5% rating it as mild. The second least common side effect appears to be heart symptoms with 51.9% reporting no experience and 32.5% rating heart symptoms as mild.

Figure 11. The questions for patients: “Have you received these side effects from your chemotherapy treatment and how strong would you rate them?” Navy blue indicates no experience, light green mild side effects, yellow moderate side effects, orange severe side effects and red very severe side effects. *Cognitive changes are related to thinking, learning, understanding or remembering.

A paper published in 2023 looking into patient-reported side effect of chemotherapy, reports fatigue as the most common side effect (87.0%) followed by loss of appetite (71.4%) and diarrhoea (49.4%) [12]. In our patient survey loss of appetite was experienced by 83.7% and diarrhoea by 67.4%, numbers even higher than those reported in the paper.

On top of the side-effect that we asked about in the survey, patients reported a wide range of different side effects including fever, insomnia, nail and skin problems (rashes, itchiness, thinning), infection due to weakened immune system (pneumonia, trigger finger), weight loss or gain, hormonal problems (thyroid, pituitary gland), changes in body temperature (sensitivity to cold, sweating), changes in sense of taste, sexual reluctance, early menopause and infertility. In conclusion, our results show that people experience a wide range of different side effects, and the experience varies a lot between people even if some of the side effects are experienced by most. This can be affected by different chemotherapeutic agents used in treatment. In the study by Katta et al., they noticed a significant effect of a patient’s cancer type on the frequency of experienced side effects [12].

To address where our motivation sparked from, our model drug doxorubicin, we also asked if patients had received it and 10.9% said they had and 14.0% were not sure. However, when asked about side effect of doxorubicin, many pointed out that it is hard to distinguish between effects of different treatments and drugs since multiple agents are often combined in treatment. Some of the patients told us that they had received other chemotherapy drugs, such as Docetaxel, Carboplatin and R-CHOP, ABDV or BEACOPP regimen.

We were deeply moved by the personal stories of side effects shared by patients. To help you understand their experiences, we've included some of their quotes below.


“I could only sleep a couple of hours a week after the chemo. My head was all messed up. Later I was given a sleeping pill which helped me sleep a bit better.”


“Taste changes - almost all food and drink, including fresh tap water,
tasted either like cardboard and sawdust or downright awful.”


“Fatigue and feeling uncomfortable. Days passed lying down,
with no strength to do anything.”


“Neutropenic pneumonia, which led to intensive care and a long-term decline in physical fitness. It was a shame when I could no longer play with my children and could not get on and off the floor with reasonable difficulty.”


“Since the chemotherapy, there has been nausea and loss of appetite, which exacerbates the underlying fatigue.”


While the immediate side effects of chemotherapy may be well-known, it's important to consider the lasting consequences. Almost half of the patients (46.5%) told us that they had experienced long-term side effects, besides the fact that many of them had received chemotherapy for the first time in recent years. Therefore, it wasn’t surprising when 32.6% of patients were not sure if they had experienced long-term side effects, because it can be challenging to distinguish whether there will be long-term effects or not. Rest of the patients (20.9%) had not suffered any long-term side effects.

For long-term side effects respondents mentioned neuropathy, feeling tired, weakened balance, stiffness and pain in joints, changes in gut-function, cognitive changes (brain fog, loss of focus, forgetfulness), weakened eyesight and hearing, heart symptoms, hormonal problems (hypothyroidism), sexual reluctance, menopause, infertility and more.


“Neuropathy affects many things. Hands or fingers are so numb,
that even simple actions are challenging.” 


“Poor fitness, low energy levels, continuing fatigue, hair loss,
severe daily tinnitus, makes life difficult in general.”


“Fatigue, insomnia and cognitive symptoms (impaired memory, reduced concentration, brain fog). I have had to take long periods of sick leave because I am unable to do information-intensive work. I have also had to stop exercising because my body can no longer take it.”


Besides side effects experienced by the patients, we asked the non-patients to choose the side effect that they associate with chemotherapy (Figure 12). We wanted to know if the idea of chemotherapy side effects aligns with patient experience. The most voted side effects were hair loss (94.0%), weakness (91.0%) and nausea (84.3%) followed by loss of appetite (73.5%) and vomiting (70.5%). Based on the patient survey results, hair loss and weakness were the most common side effects and non-patient survey shows that those effects are also known (Figure 11). Nausea and loss of appetite are also common side effects and known. Vomiting is often (70.5%) associated with chemotherapy but majority (63.6%) of patients said that they had not experienced it. On the other hand, the least known side effect seems to be peripheral neuropathy (11.4%), but majority (68.2%) of patients said that they are experiencing it. Other not so well known, but commonly experienced side effects were cognitive changes and constipation.

Figure 12. The questions for non-patients: “What side effects do you associate with chemotherapy?” *Cognitive changes are related to thinking, learning, understanding or remembering.

In the open response area, non-patients mentioned fatigue, changes in taste and smell, skin and nail changes, weak immunity, feeling cold, hormonal changes, weight loss and negative mental health effects, showing that some respondents had a more diverse idea of chemotherapy side effects. We discussed these results with Jenni Tamminen-Sirkiä, and she pointed out that often non-patients associate more visible side effects with chemotherapy. Side effects such as peripheral neuropathy and cognitive changes are often something that others than the patient cannot notice. [2]

From non-patients we also asked them if they knew someone who had received especially chemotherapy (64.9% knew and 35.1% didn’t) and how severe side effects they thought those people received (Figure 13).

Figure 13. The questions for non-patients: “How would you rate the severity of chemotherapy side effects based on your knowledge of their experience?”

The graph shows that majority considered the side effects to be severe (39.8%), moderate (31.6%) and very severe (21.4%). Compared with how severe patients rated the side-effects, non-patients rated side effects to be more severe. Patients might rate side effect lower, because they are better able to place the experience on a scale compared to other patient’s experience. Patients more than non-patients might know a lot about possible side effects and might have interacted with a lot of people experiencing severe side effects, for example in peer-support groups.

We then asked the non-patients, in what way has the patients experience of chemotherapy affected their own view on chemotherapy. The thoughts were similar as with cancer patients. A lot of people said it seemed very difficult, and a lot of people didn’t realize that it requires many treatment cycles. On the other hand, some of the non-patients said that it wasn’t as scary anymore now that they knew more about it. Many of the non-patients were still left conflicted about chemotherapy:


"I now wonder if it's even worth giving chemotherapy if you have advanced cancer. It's everyone's decision, of course, but if I were in that situation, I think I would refuse chemotherapy. But if the prognosis is good, the chance of a complete cure is always worth the suffering."


"I don't know if I would agree to similar treatments myself,
because they didn't work in the end but had a significant impact on quality of life."


Part III - Communication and Information

Communication with Healthcare Professionals

Clear communication and trust between the patient and healthcare provider is an essential part of high-quality care. When both parties understand and listen to one another, it is possible to make better treatment decisions and reduce malpractice, thus improving treatment outcomes. More than half (64.52%) of the cancer patients felt that they had received enough clear information from healthcare professionals. On the other hand, 28.3% disagreed and 7.1% of the participants weren’t sure. This corresponds to the results of another survey conducted in 2023, by Association of Cancer Patients in Finland, which states that one third did not feel that they had received enough information about the efficacy, safety and quality of the medicine. [13]

To cover more of the aspects of the communication between the patients and healthcare, we asked the patients to rate how satisfied they were with the quality and extend of communication regarding their cancer diagnosis, treatment options and how they work, side effects and how to manage them (Figure 14).

More than half of the patients were satisfied (31.6% somewhat and 29.1% very) with the communication regarding their diagnosis. Yet almost one third (45 participants out of 155) were somewhat or very dissatisfied (17.4% and 11.6%). Opinions were similar regarding the communication of different treatment options, but instead of being dissatisfied (8.4% very and 10.3% somewhat) patients felt more neutral (21.9%). The patients were the most satisfied with the communication about how the treatment works, with 36.1% being very and 39.4% being somewhat satisfied. Only 1.9% answered that they were very dissatisfied, and 6.5% somewhat dissatisfied while 16.1% were neutral.

A big portion of the patients felt neutral towards the communication about the side effects (26.5%) and how to cope with them (27.1%). According to patient experience, the side effects were communicated a bit better than how to cope with them. When looking at the Figure 14 part “Side effects of your treatment”, 29.0% were somewhat and 15.5% very satisfied, and accordingly patients were somewhat (20.6%) and very dissatisfied (8.4%) with the communication. Comparing these to “How to cope with the side effects”, patients were more dissatisfied (11.0% very dissatisfied and 24.5% somewhat).

Figure 14. The questions for non-patients: “How satisfied were you with the quality and extent of communication between you and medical professionals (doctor, nurse, other) considering the topics below?”

Overall, the matters related to side effects seem to be less clearly communicated than the treatment itself. Similar knowledge was obtained in the Adherence to treatment -survey where only half of the responders said that they had received information about the possible side effects from the pharmacy, even though 90% did experience side effects [13].

Commitment to treatment is not only influenced by knowledge of the purpose, benefits and side effects of the medication, but also by the experience with the healthcare professionals. Out of 155 patients, 87 told us more about their experience regarding communication with the medical professionals. Many of the answers were stating that they have had good communication, and their nurses have been emphatic and caring.


"The staff at the chemotherapy and radiotherapy departments are absolutely wonderful. Overall, a positive surprise for the whole cancer treatment."


Still, many of the patients told us that their symptoms had been downplayed often. Overall, many people had both negative and positive experiences, mostly depending on the treatment unit or change of doctors. For example, quotes from patients:


“I called the cancer polyclinic about unbearable nerve pain in my legs -
I was advised to rest and take Panadol.”


“I have a genetic variant that clears another cytostatic agent I use from my body more slowly than normal.
When the side effects came with a delay (e.g. hair loss), the doctor did not believe it was due to the cytostatic.”


Many of the answers also stated that it was hard to get a hold of their doctor which seems to be at least partially due to continuous workload on the heath care sector, at least in Finland [14]. Many patients perceived the communication as inhuman, as many of the patients heard about their diagnosis either on the phone or by reading it themselves from OmaKanta (Finnish nationwide online service where citizens’ data is stored). The complete lack of communication can also yield sometimes to very extreme situations. For example, one of the responders said:


“I was not informed of the radiologist's suspicions of cancer in my CT scans and as a result my cancer diagnosis was delayed by years and instead of a 3 cm curable cancer tumour, I have to be treated for a widespread incurable cancer.”


In some of the cases, the patients said that they felt that the oncologist didn’t know how to comfort them. They were described as becoming paralyzed and being arrogant, cold and distant. The issues regarding the interactions with health care professionals are extremely complicated. Some professionals might naturally get along with people very well, while others don’t since everyone is an individual with their own emotions. One thing that might have an influence on this, is how doctors learn and are taught to empathise during their education’.

‘Sidenote: The education of the doctors in Finland can also reflect to the communication. In multiple M.D. degree structures, where the overall minimum credits are 360, the minimum amount of student credits regarding patient and grieving patient confrontation seems to be around 10–15 credits. This is hard to distinguish, because the course descriptions and intended learning outcomes do not clearly state how much they teach regarding patient confrontation. Usually, the main point of the courses is on for example, how to how to take a holistic view of the patient's lifestyle, for example diet, when considering a diagnosis, and not in how to address these issues with the patient. [15,16] Additionally, it does seem that in some of the general course descriptions, for example in “Cancer and palliative care”, one of the learning outcomes is to “manage a good non-verbal and verbal interaction when dealing with a cancer patient”. This does not show when the language is switched into English. [17]

Information Sources and Clarity

We asked both the patients and non-patients, where they had received information from regarding cancer and cancer treatments (Figure 15). The most common shared information source for patients and non-patients was hearing about people’s experiences online and other media. Purposeful online searching and reading scientific articles were more popular among the patients. Unmet information needs are one recorded problem among cancer patients, so to fix this the patients often seek out more from additional sources to better understand their health condition. [18]

Figure 15. The questions for patients and non-patients: “Where have you received information from about cancer and cancer treatment?”

The results varied mostly with the source being medical professionals (patients 82.7% and non-patients 29.5%), cancer associations (patients 62.2% and non-patients 12.7%) and school and other education (patients 9.0% and non-patients 51.2%). Results regarding medical professionals and cancer associations aren’t surprising since when person gets diagnosed, these are usually the first ones to approach. The information source being school and other education seems to be significantly different between the patients and non-patients (9.0% compared to 51.2%).

Regarding the clarity of the information, we asked the patients to evaluate, had they found enough clear information about cancer in general, their cancer type, treatment, side effects and how to cope with them. From non-patients we asked only about cancer in general, treatment and the side effects.

For most of the topics, cancer patients had been found and received enough clear information (Figure 16). The only topic that the majority answered moderately, was regarding how to cope with the side effects (41.30%) and similarly a little was answered by 19.3%.

Figure 16. The questions for patients: “Overall, have you been able to find or receive enough of clear information about the topics below?” The percentages in grey are answers to “Not at all”.

Based on the non-patients’ answers, the clearest information available has been about cancer in general (35.5% enough). Still majority felt regarding all the topics, that there has been enough clear information available only moderately or a little. (Figure 17)

Figure 17. The questions for non-patients: “In your experience, is there enough of clear information available about…” with the topics “Cancer in general”, “How cancer treatment works” and “Cancer treatment side effects”.

Overall, it seems that both the non-patients and patients have received and found at least moderately clear information about the topics. This insinuates the need for collective, easily accessible and low-threshold information source regarding cancer, its treatments and their side effects to mention.

Education and Health Campaigns

We asked both patients and non-patients did they receive enough information about cancer and its treatment during their education as adolescents, around the age of 13-18. The opinions varied a lot with the patients, 76.8% saying that they received no information at all. With non-patients the opinions were more evenly divided, 31.3% saying that they received no information at all, 42.8% receiving a little and moderately 20.5%. Enough amount of information was only received by 1.9% of the patients and 5.4% of the non-patients. (Figure 18)

Figure 18. The questions for both patients and non-patients: “In your opinion, did you receive enough information about cancer and cancer treatments during your education (around the age of 13-18)?”

These results are broadly explained by the age of the respondents. The education and knowledge regarding cancer has improved over the years [2], and majority of the cancer patients were aged between 45–74, while non-patients were mostly 18–34 years old. One of the patients commented:


“In the 1960s, children were not told anything about cancer, especially in schools! Adults hushed their voices when someone mentioned the scary word cancer. At that time, cancer meant that the person who had it would die soon, and children were not told about it.”


Regarding health campaigns about cancer and its treatment done by public and private sectors, the opinions among patients and non-patients were almost the same. More than half of the participants said that health campaigns deal with cancer and cancer treatment moderately well. Approximately 30.0% of both patients and non-patients said that health campaigns did poorly, and averagely 13.8% thought they did well.

Figure 19. The questions for non-patients: “How well do you think public or private sector health campaigns deal with cancer and cancer treatments?”

As a follow-up question, we asked people to openly tell what could be done to improve the public awareness of cancer and its treatments. Majority of the non-patients’ answers (around 35.0%) stated that the public awareness and understanding of cancer and its treatments could be improved by affecting the teaching in schools. Luckily, this is nowadays actively being done [2]. Another popular opinion among both surveys was that campaigning in different media sources should be more visible. Many participants also highlighted the importance of making the information easily accessible, for example by creating a collaborative website and tables that would summarize the key points regarding cancer: prevention, recognizing symptoms, different cancer types and treatments. A good example of successful campaigning is Pink Ribbon [19], which has become a universal symbol of breast cancer. Many people were hoping that similar campaigns would be arranged with other types of cancer as well, such as prostate cancer.

People also answered a lot, to what should be taught regarding cancer. This did vary a bit in the answers. Some said that the education should focus more on different cancer types, treatments and side effects, while other thought that the focus should be mostly on how to prevent cancer and how to recognize the most common symptoms. Many answers did say that all the aspects are equally important, but there should be some sort of distribution of what is told to whom; cancer is a vast topic and there are many other diseases that would deserve a lot of recognition as well.

One good point that was made, was that nowadays people are proficient in languages, and there could be for instance links to the latest research articles from abroad. Some respondents of the patient survey also pointed out that knowledge around cancer can sometimes be misleading. For example, people who have lung cancer despite of never smoking, feel that they are stigmatized and thought to have caused their own disease. Many respondents also talked about how people do not understand the life-long effects of experiencing cancer and cancer treatment.


“What is not understood is that along with the gratitude of life continuing,
comes the sadness of a permanently damaged body.”


Part IV - Social Impact

Cancer, Social Life and Career

With our patient survey we wanted to also investigate how cancer and cancer treatments affect different areas of people’s lives such as career and social life. We asked patients to rate the impact of cancer and cancer treatment on their relationships and social life. The answers varied with 11.6% reporting extreme impact, 30.3% significant impact, 27.7% moderate, 19.4% mild and 11.0% reporting no impact. (Figure 20)

Figure 20. The questions for patients: “How much have cancer and its treatment affected your relationships and social life?”

To understand more the reasons why they answered the way they did, we then asked patients to tell more about their experiences. Many of the patients mentioned for example weakness, treatment side effects, risk with weakened immune system and lack of energy limiting their ability to take part in social activities. Many also mentioned that other people don’t always know how to act and what to say around them, leading into a feeling of isolation. The patients reported that some of their relationships became stronger due to their experience with cancer. All in all, people’s answers reflect the diversity of experience between people and the complex emotions that come along with cancer.


“Mainly because I've been feeling sick,
I haven't had the energy to go and be around people.”


“It decreases overall quality of life.
I feel ashamed, useless, sometimes jealous.”


“Some relationships have deepened, and I value important relationships even
more after the illness. The negative impact of breast cancer and its
treatments on relationships and sexuality is significant.”


“Social activity has fallen considerably. Not everyone knows how to relate and is unaware of the effects of cancer treatments. My own frailty and risk of infection has made me think twice about attending events.”


“You don't dare to show up anywhere, you don't want to see anyone and looking in the mirror makes you cry. Isolation feels like the best option.”


“People close to me became even closer,
staying in close contact, offering help and asking how I was doing.” 


Besides other social life, we also asked the patients to evaluate the impact of cancer and cancer treatment on their career or job. The opinions in this question were very evenly distributed among the patients. Of all the patients, 24.5% reported extreme impact, 12.3% significant impact, 20.6% moderate, 20.6% mild and 21.9% no impact. Even though the majority felt that there was moderate or bigger impact on career, still around 42.5% didn’t consider it affecting their career or jobs. This is also really much depending on the cancer type and what types of treatment they are receiving [2].

Figure 21. The questions for the patients: “How much have cancer and its treatments impacted your career or job?”

We then asked people to tell more about their experiences. People mentioned long sick leaves and it being challenging to go back to work. Some people mentioned accommodations such as working less time. Some people had to retire due to cancer. Others mentioned changing careers, and some told that experiencing cancer inspired them to choose medicine or biology related fields to study.


“The workplace has tried to find solutions to keep me going in my working life.
And so everyday life goes on.”


“Still not working a full-time job. Energy is still too low.”


“The impact is huge for artisan/craftsman work,
and the cancer doctor hasn't taken my concerns seriously.
I can't work remotely, and the neurological effects affect my motor skills.”


Second-hand Impact

In the non-patient survey, 91.0% of people reported knowing someone diagnosed with cancer. We then asked them to rate how much that has affected their life and their view on cancer. With both questions the average rating is between moderate and significant, with effect on “your own life” averaging closer to moderate.

Figure 22. The questions for non-patients: “How much has knowing a person diagnosed with cancer affected your own life and your view on cancer?”

We also asked the non-patients to elaborate on their answers with open form question. The responses revealed a deep emotional impact of having a loved one diagnosed with cancer. Knowing a person with cancer has made them for example to think differently about life, what is important and mortality. Sicknesses doesn’t ask permission to occur person, it can happen to anyone at any time. Many non-patients also told that they had become more aware of their own health and made changes to their lifestyle, such as quitting smoking and exercising more. Some individuals had begun checking themselves more regularly, for example in case of breast cancer. Even thought there was many who told that they had to take a gap year from school or from work to grief and cope with loss and the sickness, many people had hope and were expressing how life should be lived in the moment.

Overall, the impact of cancer and its treatment’s side effects is significant, affecting not only the patients but very profoundly the loved ones as well. The effort of the loved ones should never be taken for granted, and therefore it’s important that they have help available for them as well.


“You wonder if you will get cancer yourself and what kind of treatments you would like. I also took out cancer insurance.”


“Having cancer is indeed traumatic, but even a serious diagnosis is not always fatal. It gave me faith that a cure is possible.”


“I did an internship in social work in the cancer ward of a specialist hospital, and my parent’s family have a history of cancer. The internship and the experiences of those close to me gave me the idea that life is worth living in the here and now. You can prevent cancer to some extent through your life choices, but ultimately life is unpredictable and can throw up all sorts of obstacles. So, there is no point in living in fear of cancer.”


Limitations

Our survey has potential limitations, such as language bias. Our survey was provided in both Finnish and English, but as the demographic shows, the participants to both surveys were also outside of Finland and from countries where English is not the main language. Noteworthy is also, that the creators of this survey are not native English speakers, and therefore translation errors might have occurred while translating both the questions and answers. Regarding the questions, we did seek out to couple of people who were native in English to review the questions for spelling and clarity. We also used different translators, proofing tools, partially Large Language Model, as well as multiple websites for spelling and language cross check, (DeepL Translator, sanakirja.fi, Gemini and Google translate) to try ensuring in the best possible way that the language bias would be kept to a minimum.

Another noteworthy limitation to the survey was sex. For patients with specific types of cancer, such as breast -, and prostate cancer, gender has a major impact. This has occasionally affected the results, which we have noted while addressing results of those questions. For example, regarding education and cancer knowledge, age can play a significant factor since over the years, education and information sources have changed rapidly.

Additionally, it is always good to keep in mind, that as we are all individuals, we interpret questions differently. This became apparent already while translating the questions. Also, with the open questions, some participants answered slightly past the question. On the other hand, this was a positive thing for us, because we felt that we got a lot more from the answers when people also answered questions, we hadn't thought of asking ourselves.

Conclusions

Our survey yielded much more information and was more comprehensive than we could have imagined. Cancer and cancer-related topics are so diverse that a survey could be conducted for each aspect separately. The answers gave us a profound understanding not only of the side effects, but how cancer and other holistic diseases affect the patients and their loved ones.

In both surveys, we asked people their opinion on how important it is to develop new cancer treatments to avoid the side effects of existing treatments. Majority of people think it is highly important, including 77.7% of non-patients and 84.5% of patients. From non-patients 0.6% think that existing treatments are enough, 3.6% think that developing new treatments is slightly important and 18,1% rate it as quite important. From patients 2.6% find it slightly important and 12.9% rate it as quite important. Patients find the development of new treatments slightly more important than non-patients, which reflects their own experience with treatment and side effects. (Figure 23)

Figure 23. The questions for non-patients: “How important it is to develop new cancer treatments to avoid side effects of existing treatments?”

Although cancer treatments have come a long way over the years, it is clear that there is still a need to develop them further. With a wide range of different cancer types, such as breast, prostate, colorectal, trachea, and brain, etc. different treatments are a necessity. Also, adult’s bodies can withstand more intensive treatments compared to children or elderly people for example. Therefore, the age of patients should also be considered when deciding on the form of treatment.

The treatment planning for cancer is always done in collaboration with the healthcare provider. Clear and effective communication between the patient, loved ones and with the healthcare unit is the key for treatment adherence and thus effective treatment. Majority of the patients were both pleased and unpleased with the communication with the healtcare, and in many cases the patients did not feel that they had been properly heard. Patients have gotten enough clear information from for example medical experts, cancer associations and by researching more themselves, while the non-patients have learned about cancer and cancer treatments mostly from people they knew, from school and from different media. The non-patients felt that there wasn’t as much clear information available regarding cancer treatments and side effects, as much as about the cancer in general. The people answered, that to raise awareness regarding cancer topics, more extensive campaigning could be done like in Pink Ribbon’s case. However, over the years, awareness and understanding of cancer has increased.

Regarding the information, one thing that people were not aware of was the long-term side effects of chemotherapy. These include for example, peripheral neuropathy, feeling tired, changes in gut function, hormonal problems, infertility, cognitive changes and so on. The side effects therefore aren’t only momentary like hair loss, weakened immune system and fever, but can be also both. Side effects affect the patients' lives in many ways.

Besides physical and mental affect, they also interfere with social lives of both the patients and loved ones. Many of the responders talked about difficulties to engage in regular activities such as going outside and work and seeing friends due to shame of losing hair for example. Also seeing a loved one going trough such a hard time had profoundly affected the non-patients. Some of the people became fearful of getting sick themselves, but many of the responders also stated how they had learned to appreciate life as it is and live in the moment.

When designing a new type of therapies to treat cancer for instance, new is not always better, and with more targeted approaches we have to also ensure that efficiency is not decreased. Improving quality of life is the main goal of all medicine and therapies, but especially with cancer treatments this doesn’t always seem to be the case considering the side effects.
