[Combined effect of UHF-hyperthermia and x-irradiation on the growth of sarcoma 45].

Repeated local exposure (6 sessions) of rat sarcoma 45 to ultrahigh-frequency hyperthermia (41.5--42.5 degrees C in the tumor for 30 minutes per session) and x-ray radiation (a single dose of 8 Gy) irrespective of the succession of their application enables complete resolution of the tumor to be attained at the logarithmic stage of its growth.
