Population Based Germline Testing for Early Detection and Prevention of Cancer

About This Trial

PROTECT-C is a research study offering genetic testing to people to see whether they have a genetic change that increases their risk of breast, ovary, bowel, and/or womb cancer. This is regardless of whether they or their families have had cancer. Breast, ovary, bowel, and womb cancers make up half of all cancers in women. Around 15-20% (15 to 20 in 100 cases) of ovary and 3-4% (3 to 4 in 100 cases) of breast, womb, and bowel cancers are linked to cancer genes and may be prevented. People with a genetic change that puts them at increased risk of any of these cancers have ways to help them manage their risk through the NHS. This may include screening to find cancers earlier when they are easier to treat, and surgery or medication to prevent cancers from developing. This can save lives. Currently, genetic testing is only available on the NHS to people who meet certain criteria. For example, those who have had certain cancers, have a strong family history of cancer, or those with Jewish ancestry. But many people may not have a strong family history or meet NHS testing criteria. This means that this system of testing misses 50% to 80% of people (50 to 80 in 100 people) who have a genetic change. It is thought that only around 3 in 100 people overall who have a genetic change that increases their risk of cancer know about it. Given the effective screening and preventive options that are available, this represents a huge, missed opportunity to prevent cancers or find them earlier. The PROTECT-C study aims to evaluate the option of offering genetic testing to everyone who may want it. This is regardless of whether they or their families have had cancer. We will offer genetic testing to 5000 people. People may take part if they: * Are over the age of 18 years and * Are a woman, trans man, or non-binary person with female reproductive organs (ovaries, fallopian tubes, and/or a uterus) and * Have never had genetic testing for the cancer genes tested for in the study and * Do not have first-degree family members (e.g.: parent, sibling, child) or second-degree family members (e.g.: aunt, uncle, niece, nephew, grandchild, grandparent, half-sibling) with genetic changes in the cancer genes tested for in the study PROTECT-C is a completely digital study. The study team will give participants access to an app developed specifically for this study. They can download this app using a smartphone or tablet or access it on any internet browser using a computer or laptop. Before they can access the app, participants will need to complete a consent form. They will also be asked to fill in a short questionnaire about themselves and their health. The PROTECT-C app contains information to help participants decide if they would like to have genetic testing. If they decide to have genetic testing, they will complete a consent form for genetic testing on the app. The study team will send them a saliva based test kit in the post. The study will look at how many people decide to have genetic testing and how many of them are found to have a genetic change. It will evaluate their experience with using the app and how this approach to genetic testing affects their quality-of-life, satisfaction, and mental well-being. This will give us a better understanding of how well the app works as a way of offering genetic testing to people. The study is interested to see how people found to be at increased risk decide to manage their risk. We will assess the uptake of screening and prevention options. Few participants will be invited to have 1:1 interviews by the study team. This will evaluate their experience of making a decision about genetic testing and taking part in the study. Taking part in these interviews is optional. The study will also assess if this way of offering genetic testing to people is affordable for the NHS.
