Early DNA Blood Test Fails to Help Direct Colon Cancer Treatment
Key Takeaway:
Using the drug trifluridine/tipiracil for colorectal cancer patients who test positive for residual tumor DNA during recovery does not successfully delay cancer recurrence.
What this means for you
This study shows that a specific chemotherapy drug did not help prevent colon cancer from returning, even when sensitive DNA blood tests showed early warning signs. Do not alter your current treatment plan.
