The Guidelines for Colorectal Cancer Treatment list indication and curative resection criteria for the endoscopic resection of mucosal and submucosal invasive colorectal cancers. Here, we report the case of a woman who underwent endoscopic mucosal resection (EMR) but should have undergone curative resection because the submucosal invasion depth in this case was 1,200 mm; however, she did not undergo additional curative surgery. Although liver and lymph node metastases were observed 7 years later, we were able to resect all of these tumors after neoadjuvant chemotherapy. We strongly recommend additional curative surgery for patients who fulfill the criteria for curative resection after EMR because of the very high recurrence rates in such cases.
