[Hyperthermia and hyperglycemia in the radiation and combined treatment of locally disseminated and recurrent rectal cancer].

The results of the use of short-term induced hyperglycemia and local UHF-hyperthermia in radiation therapy of 27 rectal cancer patients aged 17 to 65 were analysed. A primary inoperable locally disseminated tumor process was noted in 8 patients, recurring cancer in 19. A noticeable tumor regression (over 50%) was observed in 7 out of 8 patients making a radical operation possible. With computerized tomography tumor regression was recorded by over 50% in 9 out of 19 nonoperated patients. The data obtained illustrate some potentialities of raising the efficacy of radiotherapy using radiomodifiers.
