ENDOSCOPIC POLYPECTOMY OF COLONIC POLYPS WITH INVASIVE ADENOCARCINOMA - A SERIES OF 19 CASES

We review the endoscopic polypectomies done at the <<Juan Canalejo>> Hospital in the last 6 years (1984-1989). Out of a 509 adenomatous polyps, 19 showed invasive adenocarcinoma seen in 18 patients (there were two carcinomatous polyps in one single patient), 11 men and 7 women. The median age was 67 years and all of them were located in the left side of the colon or the rectum. The average size was 3 cm and the most frequent histologic type was villogandular (58%) followed by the villous (26%) and adenomatous (16%). The endoscopic resection was curative in all but one patient that presented vascular invasion in the resected polyp.
