RADIATION-THERAPY OF CAPOSIS SARCOMA WITH FAST ELECTRONES

Kaposi's sarcoma and AIDS-associated KaPosi's sarcoma resistant to che motherapy were irradiated locally in 14 and 1 patient, respectively, a nd followed up for 1-6 years. The energy (10 MeV) in the total focal d ose of 24-40 Gy was emitted as high-speed electrons from a medical acc elerator. An immediate response was obtained in all the patients. The recurrence occurred in AIDS-associated sarcoma only. It is recommended that Kaposi's sarcoma should be treated by high-speed electron radiat ion covering the lesion and adjacent sites of the intact skin. Total f ocal dose must not exceed 30 Gy, in case of circulatory disturbances i n the low limbs the dose is to be reduced to 20 Gy.
