Colonoscopy and the Management of Polyps Containing Invasive Carcinoma
Year: 1978
Type: article
Study design: Observational Study
Abstract: Experiences with 565 colonoscopic polypectomies and 91 colonic and rectal resections containing infiltrating carcinoma in polyps are reviewed. A plan of management based on pathologic study of resected polyps is formulated to avoid further unnecessary surgery. It was concluded that: (1) Tubular adenomas containing invasive carcinomas have a low incidence of metastatic node involvement. This incidence is related to the depth of carcinomatous involvement. Resection of these polyps with a margin free of carcinoma constitutes definitive and adequate treatment and that (2) Villous adenomas containing invasive carcinoma have a high incidence of metastatic nodal involvement, and operative resection of the involved area of the colon is recommended, and that (3) Pedunculated tubulovillous adenomas containing invasive carcinoma behave like tubular adenomas, and the recommendations for further surgery in the patient with tubular adenomas with carcinoma apply equally well for these lesions. Sessile tubulovillous polyps tend to behave like villous adenomas, and if invasive carcinoma is demonstrated, further operation is recommended.
