Abstract
Conclusions Local treatment of carcinomain situ of the rectum is the procedure of choice. It is also preferable when there is a focal malignant change in a polyp with a pedicle that is not invaded by the cancer, and when a sessile carcinoma of low grade is less than 2 cm. in diameter. These indications may be extended in some cases when the general condition of the patient precludes a radical surgical procedure, when the patient, because of a poor mental condition, would not be able to manage the colostomy himself, and when a colostomy is refused. When a carcinoma of the rectum is inoperable, or when there is distant metastasis, local treatment may provide gratifying palliation.
