[Local irradiation planning in prostatic cancer with the use of optimized dosage field variants]

A method of dosimetric planning of multifield local irradiation of prostatic cancer using a file of optimized dose fields was proposed (the fields were computed for concrete patients). Basic charts were used to choose a necessary dose field, then the time of irradiation is computed in present directions for each concrete patient. The method was tested during the treatment of 19 patients who were given a course of radiotherapy in an outpatient setting. A continuous course of radiotherapy at a dose of 70-74 Gy was delivered. Radiation reactions of the rectum were insignificant, and they were eliminated without discontinuation of a course of irradiation.
