Background and Objectives Optimal adjuvant treatment for patients with Stage I/II colon cancer with micrometastases (MM) is unknown. Because there is no known adjuvant treatment-related benefit, we evaluated whether MM influenced treatment decisions. Method Review of a national survey from members of the SSO and ASCO. Results Of 602 survey responses, 305 (51%) stated that MM had significant prognostic value, 250 (42%) were unsure, and 47 (7%) did not believe that MM held prognostic value. Three hundred seventy-four (63%) would offer adjuvant therapy in the setting of MM, while 222 (37%) would not. Only 15% routinely performed IHC on lymph nodes. Medical oncologists were more likely to recommend adjuvant therapy compared to surgical oncologists (68% vs. 51%, P?=?0.001). Conclusions MM in colon cancer apparently influenced adjuvant treatment decisions absent known prognostic benefit. Prospective trials are needed to improve the selection of patients for systemic chemotherapy in early, node-negative colon cancer. J. Surg. Oncol. 2012; 106:119122.
