title: Surgical treatment of renal cell carcinoma metastases: prognostic significance.
abstract: Between January 1980 and March 1993, 166 patients with renal cell carcinoma were treated at Nagoya University Hospital. Among them 16 (9.6%) underwent surgical removal of 21 metastatic lesions: 12 patients had distant metastases at diagnosis and the other 4 demonstrated new distant metastases during their clinical course after nephrectomy. The metastatic lesions involved the brain in 6 patients, bone in 4, lung in 2, contralateral adrenal glands in 2, soft tissues in 2, lymph nodes in 2, pleura in 1, pancreas in 1, and contralateral renal pelvis in 1. All of the 16 patients underwent nephrectomy and 15 of them (93%) received interferon-alpha therapy. Patients with lesions which were completely resected had significantly longer survival than those with lesions which were palliatively treated and those with metastatic lesions at other sites (p = 0.02). Improvement of performance status was observed in 5 of 6 (83%) patients undergoing palliative surgical treatment. The present study suggests that surgical removal of metastatic lesions prolongs survival in a limited number of renal cell carcinoma patients and that it improves performance status in those symptoms related to metastasis.
