Rapid fractionation technique and re-treatment of cerebral metastases by irradiation

Abstract

A total of 131 courses of treatment has been evaluated in 81 patients. Sixty-eight percent of the courses were given as a single dose of 1000 rads. The remainder were treated with a short course of less than 1 week. When symptoms recurred and patient status indicated the necessity, 35 patients were retreated for the second time, 12 for the third time, and 3 patients for a fourth course. Results were evaluated through survival and degree and duration of improvement.
