[Restriction of indications and first results with the high-dose rate-afterloading technic (iridium-192)].

First experiences with high-dose-afterloading technique (Iridium-192) at the Department for Radiotherapy of the Gynecologic-University-Clinics in Vienna are reported. 1300 applications in about 500 patients were performed. With the one-sound Buchler-apparatus theoretically all forms of isodoses are possible, but in practice we have restricted the indications. Only Radium uterine sounds as well as radium vaginal applications were replaced by high-dose-afterloading technique. Generally only primary or postoperative treatment of endometrial carcinoma was performed. The easy sounding of the uterine cavum is another reason for this restriction of indications. The first results of radiotherapy of endometrial cancer yet shows little better survival rates without any increase of side effects.
