 The aim of this study was to determine a surveillance program after endoscopic resection for patients with SM invasive colorectal carcinoma. We investigated 107 patients who were treated with endoscopic resection for SM invasive colorectal carcinoma and 1,666 patients who were checked for recurrence for over five years after curative resection for colorectal cancer. In endoscopic resection, 8 cases showed recurrence. Recurrence within 3 years after endoscopic resection was common. In surgical resection, most local recurrence occurred within less than 3 years. CEA and CT were most effective modalities for the detection of local recurrence. It is concluded that surveillance for patients of sm cancer who have been treated by endoscopic resection should be performed by colonoscopy and other modalities such as CEA/CA19-9, CT, MRI and PET until more than 5 years have passed.
