[New aspects in the treatment of the hypernephroid carcinoma of the kidneys (author's transl)].

The nowadays best treatment of the hypernephroid carcinoma of the kidneys is the radical tumornephrectomy with following supervoltage-radiation. Recently before any surgical treatment a short radiation with a dose of 1 500 up to 2 000 R is recommended. Hereby a preoperative devitalization of tumor-cells should be achieved. An application of cytostatica would be useless. Sometimes in generalized cancers a recession of the metastases and a stagnation of the growth of the tumor for a long time can be achieved by the application of gestagens. The statistical analysis of results won in a clinic or by some defined modalities of treatment respectively the comparison of these results with the ones won by other authors is rather difficult. This would demand comparable collectives of patients. With the relative rarity of kidney cancers this would be only possible if many clinics would co-operate on a national and international base and if the modalities of treatment were equal. Not before the question for the best therapy of the hypernephroid carcinoma of the kidneys can be answered.
