First seen Apr 21, 2026 · Last updated Jun 16, 2026 · Updated 11 times
Summary
This early-stage study tests whether a blood test that detects tiny amounts of cancer DNA (ctDNA) can help doctors decide when to switch chemotherapy for colon cancer patients who still have signs of disease after surgery. About 22 adults with stage II–IV colon cancer will receive a combination of two chemotherapy drugs (trifluridine/tipiracil and irinotecan) if their ctDNA test remains positive. The main goal is to see if this approach can clear the ctDNA, indicating the treatment is working.
