Surveys for Colorectal Cancer
Since our project is based around colorectal cancer, we decided to send out surveys to get a better understanding of our project and improve it as much as possible. We devided our survey into 3 different parts: patients of colorectal cancer, healthcare workers in this field, and the general public to be able to see what people in general know about colorectal cancer. The part of the survey targeting the patients focuses on how the patients feel during their treatment and their mental well-being. We asked questions like “Did you feel that your concerns were heard during treatment?” For the healthcare workers, we focused our questions mainly on the detection methods for colorectal cancer available and asking them their honest opinion on having a bacterial biosensor as a method of detection of colorectal cancer. For the general public, we asked questions that would help us understand what the people in general know about colorectal cancer and the symptoms that could help them recognize the presence of colorectal cancer.
In all sections of the surveys, we asked what people thought about the idea of taking a pill that contained a bacterial biosensor to detect colorectal cancer, to get an idea of the public perception on our project. We got answers mostly from Belgium and Spain and even some answers from doctors and it surprised us that so many people were willing to take an engineered pill. The results were discussed and exchanged with iGEM Wageningen, since they also worked on colorectal cancer and also had a survey sent around in the Netherlands. This way we could see if the public opinion in different countries is the same.
Results:
“In order to get a thorough notion on the perspective of different groups of people in colorectal cancer (CRC) and their opinion on ingesting a bacterial biosensor for CRC, we conducted a survey divided into 3 sections aiming for healthcare workers, patients of CRC and general public.
In the section aimed at healthcare workers, we focused on their opinion on current detection methods and the possibility of a genetically engineered bacteria as a detection method. Around 60% of them considered today’s methods not sufficient because of invasiveness, non-specificity and cost. 72% of them would recommend a pill containing the biosensor to their patients. However, they would first like to get more details such as: cost, side effects, efficiency and biosafety.
We only managed to get one patient with CRC (Spanish survey), who considered their concerns were not heard during treatment/diagnosis and was willing to take our biosensor, believing it would be efficient and present less side effects than conventional methods. They would like to know when should they take it and if its dependent on the symptoms.
Regarding the general public, vast majority was familiar with CRC (from friends, family who had it), even though their knowledge about it wasn’t quite accurate (location, symptoms, prevention). A great number of them (56%) consider they would need more information beforehand in order to take our biosensor, the rest (44%) would take it nevertheless. That is interesting, considering only 23% of them knew what a biosensor is. Big majority believes it would be efficient and present less side effects than conventional methods.
Things we didn’t mention and people considered relevant: study CRC trigger, asked if it was genetic, contraindications of taking our biosensor while having other pathologies, long-term side effects, different effect in gender/family history/habits.”
