[Brachytherapy of prostatic carcinoma, 60Co high dose rate, remote after-loading methods]

Six patients with prostatic carcinoma, including 2 with Stage B, 2 with Stage C, 2 with Stage D1, received transurethral irradiation (TUI) using 60Co high dose rate, remote afterloading methods, in combination with external irradiation by 4 MV X-ray. Total tumor doses were 97.0 to 129.3 in TDF and needle biopsy performed 3 mo after the treatment proved to be free of cancer cell in 5 patients and almost no viable cancer cell in one patient. No adverse reactions were encountered in any patient. We believe that TUI is a useful treatment for prostatic carcinoma.
