 We evaluated the Japanese guidelines for SM-CRC(submucosal invasive colorectal cancer)retrospectively from long-term outcomes of SM-CRC. A total of 626 patients with SM-CRC were involved in this study. Of 626 patients, 105 patients were treated by ER(endoscopic resection)alone with low risk of pathological features for lymph-node metastasis. The clinical outcomes were 1.9%(2/105)in recurrence rate, 98% in relapse-free interval, and 93% in overall survival. Regarding recurrence, while there were not significant numbers, patients with high risk treated by ER alone tended to be more numerous than those treated by ER and additional surgery. From this study, In SM-CRC patients with four low risk pathological factors, long-term outcomes of endoscopic resection alone were sufficiently good. In those with high risk pathological features, subsequent surgery could be recommended because of the higher recurrence rate after endoscopic resection alone.
