Hepatectomy for metastatic renal cell carcinoma.

The experience with hepatectomy for metastatic renal cell carcinoma (RCC) has been very rarely reported, because multiple organ metastases ordinarily coexist when hepatic metastases are found out. Three patients who underwent hepatectomy for metastatic RCC are presented here. Radical nephrectomy was performed for the primary renal lesions in all the patients, and their hepatic metastases were resected simultaneously in one of them with a solitary tumor, and about one month later in two of them with multiple (3 and 6) tumors. These operations produced no distinct complications. The patients with 1 and 3 hepatic metastatic lesions survived without tumor recurrence for 12 and 21 months, respectively, while the patient with 6 hepatic metastatic lesions had tumor-free interval of only 2 months and died 10 months after hepatectomy due to lung metastasis. Hepatectomy may be the only promising treatment for hepatic metastases from RCC, but the indication for surgery should be evaluated according to the number of hepatic metastases.
