[Experiences with Depo-Provera (medroxyprogesterone) in the treatment of kidney tumors].

: 30 patients with renal tumours were treated with Depo-Provera (Medroxyprogesterone). Among the 21 patients operated on without metastases and with an parallel metastasis (fibrous capsule, adipose capsule, peritoneum) in the course of 6 to 15 months no one died of a tumour progression. Among the 9 patients with a distant metastasis in one case the regression of the metastasis could be achieved, whereas in another case progesterone stopped the progression of the intraoperatively observed liver metastasis.
