Experience with thermoradiotherapy of malignant tumors

: The authors analyzed immediate, short-term results of thermoradiotherapy of 112 patients and radiotherapy alone of 91 patients (control group). All had tumors of different sites. Local hyperthermia used as an adjuvant to radiotherapy made it possible to increase the frequency of complete tumor regression from 0 to 11% in rectal cancer patients, from 86 to 100% in head and neck cancer patients, from 0 to 14% in the patients with soft tissue sarcomas and from 40 to 71% in children with rhabdomyosarcomas. These results suggest a possibility of raising the efficacy of radiotherapy combined with local electromagnetic hyperthermia.
