Diagnosis clinical trials at UCSD

This pilot study will assess whether a larger study of stool testing for colorectal cancer is practical. It plans to enroll 40 adults born in 1960 or later who have new symptoms that could be related to colorectal cancer. Participants will collect a stool sample at home using a fecal immunochemical test (FIT), complete a questionnaire, and undergo blood tests and colonoscopy as part of their usual medical care. Researchers will compare research FIT results with colonoscopy findings and assess recruitment, sample collection, and completion of study activities. Research FIT results will not routinely be shared with participants or their clinicians. If a research FIT result is abnormal and colonoscopy has not been completed within six months, the study team will notify the primary care provider to encourage colonoscopy follow-up.
