Summary
This study tests a new drug called QL1706 given before surgery for people with a specific type of colon cancer (MSI-H/dMMR) that has not spread far. About 363 participants will receive either QL1706 or standard care. The goal is to see if QL1706 can eliminate more tumor tissue before surgery and improve long-term outcomes. Participants must have good organ function and no prior cancer treatment.
