[Clinical x-ray and morphological changes in breast carcinomas during radiothermotherapy].

Clinico-roentgeno-morphological investigation established a marked regression of tumor in as many as 86.1% out of 230 patients with stage IIB and III breast cancer who had undergone radiothermotherapy. Morphologically confirmed complete regression was observed in 12.6% of patients with lesions smaller than 3 cm in diameter at presentation. Treatment was followed by massive necrosis, dystrophic changes and inhibition of mitotic activity of tumor cells in patients with stage III cancer and those with stage IIB who had presented with tumors larger than 3 cm in diameter. However, in all these cases viable tumor cells were still observed at the periphery of tumor.
