Summary

This study looked at over 3,600 people with early to mid-stage colon cancer to see where cancer spreads to lymph nodes and how much bowel and surrounding tissue should be removed during surgery. The goal was to provide clear evidence for surgeons on the best way to operate. Participants were observed after their surgery to track their recovery and long-term outcomes.
