The number of lymph nodes examined debate in colon cancer: how much is enough?

Background: Much debate exists over the significance of the number of lymph nodes (LN) examined after colon resection.

Materials And Methods: The Surveillance, Epidemiology and End Results (SEER) database was queried for patients who presented with colonic adenocarcinoma. Multiple Cox proportional hazard regressions were run using successive LN cut-offs (6-26), first controlling for and then stratifying by T-stage.
