Abstract

• Fifty-three patients were treated for pedunculated adenomatous polyps that contained foci of invasive cancer confined to the stroma. This entity is a stage of malignant involvement intermediate between in situ carcinoma and frank infiltrative cancer that invades the muscularis mucosae. Metastases to regional lymphatics were not observed. Local removal of such lesions without regional lymphadenectomy is adequate treatment.
