To determine the effect on survival of excision of a solitary metastasis from renal cell carcinoma, the records of 29 patients seen at our institute within the last 15 years (1972 to 1986) who underwent such an operation were reviewed. Metastasis was present at diagnosis in 11 of the 29 patients, while 18 had metastasis 2 months to 11 years after nephrectomy, with an average interval free of disease of 38 months. There were 13 pulmonary metastases, 6 bone lesions and 10 other lesions. The estimated over-all survival rate for this group was 41 per cent at 2 years and 13 per cent at 5 years after excision of the metastasis. Only 2 of the 29 patients currently are alive with no evidence of disease 42 and 53 months since excision of the metastasis. Neither the presence nor absence of a metastasis at diagnosis nor the interval between nephrectomy and the development of a metastasis in patients without metastatic disease at diagnosis appeared to influence survival after excision of the metastasis. Unlike previous reports, these results suggest that the beneficial effects of excision of metastatic renal cell carcinoma are limited to improved short-term survival postoperatively and that surgical cure of patients with metastatic renal cell carcinoma is a relatively uncommon event.
