Distance of resection margin affects anastomotic recurrence in colon cancer

In a study of 1,958 colon cancer patients, a lower distal resection margin distance, advanced N stage, and fewer lymph nodes dissected were associated with increased risk of anastomotic recurrence (AR). The 3-year AR risk was lowest when the proximal resection margin was ≥6 cm, and it increased if the distal margin was <3 cm. Prognosis for AR was similar to nonanastomotic local recurrence (NAR), despite a higher radical surgery rate for AR.

• Why it matters: Lower resection margin distance increases colon cancer recurrence risk.
