[Thermoradiotherapy in locally extensive soft tissue sarcoma].

The report discusses 138 cases of soft-tissue sarcoma: 92 patients initially received thermoradiotherapy, 46-radiotherapy. Local electromagnetic hyperthermia was found to potentiate the antitumor effect of ionizing radiation and to be followed by a significant increase in the frequency of complete and considerable regression of tumor, as compared with exposure to total doses of 30-32 Gy (66-70 Units). As a result, 5-year survival rate in cases of post-thermoradiotherapy conservative surgery rose to 54 +/- 5.2%, as compared with 26 +/- 6.8% after conservative surgery + radiotherapy. The percentage of patients who survived more than 5 years after conservative surgery + thermoradiotherapy or radiotherapy was 37 +/- 7 and 23 +/- 7.8, respectively.
