ID: 3523886 LONG-TERM OUTCOMES AND SURVIVAL AFTER ENDOSCOPIC OR SURGICAL RESECTION FOR T1 COLORECTAL CANCER: A MULTICENTER RETROSPECTIVE STUDY

According to the American Gastroenterological Association (AGA) guidelines, the curative criteria of endoscopic resection (ER) for T1 colorectal cancer (CRC) are well/moderately differentiated adenocarcinoma or papillary carcinoma, no lympho-vascular invasion, submucosal invasion depth <1000μm, and budding grade (BD) 1. Although an additional surgery is recommended for non-curative ER, the incidence of lymph node metastasis (LNM) is less than 12%. Some patients do not undergo surgery due to their old age and perspective in clinical practice, their clinical outcomes are not fully evaluated.
