 The applicability of CFP(cold forceps polypectomy)was investigated by examining the maximum diameter of 16,882 colorectal endoscopically or surgically resected tumors. The cancer rates and submucosal invasion rates of the tumors were also examined. The cancer and submucosal invasion rates for 0-Ip, 0-Isp, 0-Is, and 0-IIa of 5mm or smaller were low in each 2.3%(124/5,444), 0.1%(7/5,444). The cancer and submucosal invasion rates to 0-IIc and 0-IIa+IIc of 5mm or smaller were high in each 35.1%(13/37), 24.3%(9/37). The rates of en bloc endoscopic resection and pathologies were high in each 77.8%(777/999). The tissues included 783 low-grade adenoma(78.4%)samples. The incomplete pathological factors were without mucosal mucosae, measured 4-5mm in diameter, and the vertical direction of CFP.
