Abstract
Background and purpose: We previously reported that preceding endoscopic resection (ER) for T1 colorectal carcinoma (CRC) requiring additional surgery had no effect on patient’s prognosis (J Gastroenterol 2019). In addition, the Japanese Society for Cancer of the Colon and Rectum stated that the vertical tumor margin distance (the distance from the deepest invasion portion of carcinoma to the marginal termination resected by ER) of 500 μm or more is desirable for ER to reduce lymph node (LN) metastases. We analyzed the influence of vertical margin distance of ER for T1b (submucosal invasion > 1000μm) CRC on the metastatic recurrence and prognosis of patients who underwent additional surgery after ER.
