In this study, we summarized 286 patients who underwent colonoscopic polypectomy and analyzed the features of 22 patients with malignant polyps including 3 laparotomy cases treated between 1974 and 1985.<BR>Polyps as well as malignant tumors occurred mainly in the sigmoid colon and adenoma was the main histological diagnosis in these polypectomy cases.<BR>Of twenty-two patients with malignant polyps, 19 patients underwent colonoscopic polypectomy, and 3 patients were treated by laparotomy.<BR>In 4 patients given polypectomy, cancer cells had already invaded the submucosa. Two of these were subsequently treated by radical surgey, and the other two were followed up without surgery, because cancer cells had not invaded the lymphatic vessels and submucosal invasion was very slight.
