ClinConnect Summary

This clinical trial is focused on studying Lynch syndrome, a hereditary condition that increases the risk of colorectal cancer, in patients who are undergoing surgery for colorectal cancer in Türkiye. The research aims to find out how common Lynch syndrome is among these patients by looking at their cancer tissues and performing specific tests to check for genetic changes. Over the course of a year, patients aged 18 and older who have been diagnosed with colorectal cancer and are having surgery will be invited to participate. They will need to provide a sample of their tumor tissue for testing, and they must agree to participate in the study and undergo additional genetic testing if needed.

Eligible participants can expect to have their tumor analyzed to see if there are any changes related to Lynch syndrome. Depending on the results, they might undergo further genetic testing to understand their risk better. The study is not yet recruiting participants, but if you or someone you know is diagnosed with colorectal cancer and meets the eligibility criteria, this trial could provide valuable information about their health and family risk factors.
