Testing blood tumor DNA in digestive and breast cancers
Treatments studied
Part of Cancer, Digestive system, Skin clinical trials.
This study looks at a blood test for “circulating tumor DNA” (tiny pieces of cancer-related DNA in the blood). It may help doctors learn more about digestive, gynecologic, or breast cancers and how patients respond when treatment like chemotherapy or immunotherapy is needed.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You have (or your doctors strongly suspect) digestive, gynecologic, or breast cancer and need cancer treatment such as chemotherapy or immunotherapy
- You can legally take part as an adult
- You must be covered by France’s Social Security or an accepted third-party payment system
- You will receive a clear explanation of the study and agree to participate (with a recorded non-opposition)
- You should not have refused participation because of language barriers or feeling unable to understand or sign the consent
- You should not have had another type of cancer in the past 5 years (except the cancer being studied)

This study checks whether a blood test that looks for “tumor DNA” (circulating tumor DNA) can help evaluate how well neoadjuvant chemotherapy worked for breast cancer. It may help doctors better understand treatment response after surgery.
This study looks for tiny bits of tumor DNA in your blood after surgery to see if it can help guide future treatment. It's for people who had surgery first (not chemotherapy before surgery) and have not seen the cancer spread.
This trial looks at blood samples to measure substances that may reflect cancer (tumor markers). It may help doctors understand cancer better and improve future monitoring, as long as you can safely and regularly take part.
This trial looks at tumor cells in the blood of women with breast cancer to understand them better. It may help doctors learn more about how the disease spreads.
This study builds a clinical and biological database for people newly diagnosed with certain cancers. It may help doctors better understand cancer patterns and improve future care, and it involves agreeing to extra blood samples.
This study looks at circulating tumor DNA, which is tiny bits of DNA found in blood, to help assess how solid tumors are responding early. It uses blood samples from healthy adults who are willing to donate.
