Complete regression of multiple pulmonary metastases in a patient with advanced renal cell carcinoma treated by occlusion of the renal artery with subsequent radical nephrectomy and progesterone.

We report on a 51-year-old male patient who presented with a renal cell carcinoma of advanced stage including multiple pulmonary metastases. A complete regression of the pulmonary metastases was observed after embolisation of the tumor-bearing kidney with subsequent nephrectomy and progesterone treatment. 27 months after the operation the patient is in excellent health without recurrence of metastases.
