[Thermoradiotherapy of the late stages of cancer of the oral mucosa and oropharynx].

Local UHF-hyperthermia (915 MHz) of cancer of the oral mucosa at advanced stages ensures higher immediate cure rates (48.9 +/- 7.5%) as compared to radiotherapy (26.8 +/- 6.9%). 30-min. hyperthermia before irradiation turned out more effective than 60-min. hyperthermia. Hyperthermia was attended by side-effects (fatigue and sweating, vertigo and pain in the zone of heating). Hyperthermia was not tolerated by 10.7% of patients. Fixed metal prostheses and crowns in the zone of planned hyperthermia should be removed.
