Angioinfarction plus nephrectomy for metastatic renal cell carcinoma--an update.
We treated 100 patients with metastatic renal cell carcinoma by angioinfarction of the primary tumor followed by radical nephrectomy. Of the patients 88 also received postoperative parenteral progesterones. We achieved an over-all response rate of 28 per cent (complete regression of all metastatic lesions in 7 patients, regression greater than 50 per cent in 8 and stabilization for at least 1 year in 13). Patients with parenchymal pulmonary metastases only have the best survival rate (64 per cent at 1 year) and are most likely to benefit from angioinfarction and nephrectomy. The presence of hilar or mediastinal adenopathy, pleural effusion or nonpulmonary metastases confers a worse prognosis. These patients do not appear to survive longer with preoperative angioinfarction than if treated by nephrectomy alone. Our data demonstrate that it is critically important to stratify patients by site and volume of disease when results are reported and compared for any patient undergoing treatment for metastatic renal cell carcinoma.
