Resection of pulmonary metastases from renal cell carcinoma.
Between 1980 and 1995, 77 patients underwent complete resection of pulmonary metastases from a renal cell carcinoma after exclusion of a primary tumor recurrence and other metastatic localizations. 30-day mortality was 3%. The Median follow-up was 34 months (M). Cumulative 5-year survival (5-YS) was 39%. Prognostic criteria are the duration of the disease-free interval (DFI) and the number of metastases. Patients with a DFI > or = 48 M had a 5-YS of 46% compared to 26% for a DFI of < 48 M. Patients with a solitary metastasis had a 5-YS of 49% compared to 19% for multiple metastases. There was no significant difference in terms of sex, kind of access, kind of operation, and unilateral or bilateral affection. Since metastases from renal cell carcinomas are almost resistant to chemotherapy and radiotherapy and immunotherapy at present does not considerably improve long-term survival, surgical resection currently is the only effective therapeutic access in renal cell cancer metastasized to the lung.
