✦ Synopsis

One hundred forty-seven patients with astrocytoma were treated between 1942 and 1967. There were 25 postoperative deaths. The 14 patients in whom the tumor was thought to have been completely removed were not irradiated and all survived 5 years or longer. Seventy-one of the 108 patients with incompletely excised lesions received radiation therapy. The 5-year survival rate for those with incomplete resection alone was 19%, compared to 46% when ir- radiation was given. Based on observations up to 20 years, after incomplete removal postoperative irradiation significantly prolonged useful life and may have lead to permanent control in some. There was no evidence of radiation damage. Most of these tumors were fibrillary astrocytomas, and the results apply particularly to this histologic type. Only 1 of 1 1 patients with gemistocytic astrocytoma survived 5 years. The survival rate for Grade I tumors was appreciably greater than for Grade I1 lesions; in both grades, it was improved by irradiation.

Superfractionation (SF) radiation therapy is the administration of three fractions per day. We have assessed the effect of SF in a prospective randomized clinical study of malignant astrocytomas from July 1978 to December 1980.

Radiation therapy has assumed an integral role in the treatment of rectal carcinoma. The major role is in the surgical adjuvant setting in which the addition of radiation therapy can decrease the risk of local failure from up to 50% for stages B2 and C, to approximately 20%.
