title: [Planning combined radiation therapy of rectal cancer taking into account the biological effect of the radiation].
abstract: Biologically equivalent doses with various single values, fractionation, irradiated areas, relative biological efficacy, the time of radiation therapy for schedules of intracavitary and gamma-beam radiotherapy were determined for concomitant radiotherapy of rectal cancer patients. A radiation effect implementation factor was introduced making it possible to sum up equivalent dose values in critical points and to obtain equivalent isodose distributions.
