[Clinical results of pre-operative irradiation in case of adenocarcinoma of the kidney (author's transl)].

145 patients with adenocarcinomas of the kidney were submitted to tumor resection and irradiation. The irradiation was executed before the operation (in most cases with a focal dose of 1200 to 1600 rd in two days or 2400 to 3500 rd in 2 1/2 to 3 1/2 weeks) and/or after the operation. The survival rates of the different therapy groups were examined with regard to the tumor extension and to its degree of differentiation. It was found out that the pre-operative short term irradiation was somewhat superior to the pre-operative long term irradiation except in case of very extensive, hardly operable tumors. On the whole, the combined pre- and post-operative irradiation seems to be more advantageous than the post-operative irradiation alone.
