Nephron-sparing surgery for renal cell carcinoma with venous involvement.
A nephron-sparing operation recently has been shown to provide extended survival free of disease in selected patients with localized renal cell carcinoma, particularly for tumors of lower stage. To define better the role of conservative surgical treatment in more locally advanced renal cell carcinoma we reviewed 9 patients with venous tumor involvement in solitary functioning kidneys who underwent a nephron-sparing operation. Complete tumor resection with adequate preservation of renal function was accomplished in all cases. Of the 9 patients 5 had no evidence of disease 7 to 93 months (mean 33.2 months) postoperatively. The remaining 4 patients died of metastatic renal cell carcinoma 17 to 47 months (mean 35.5 months) postoperatively, 2 of whom had concomitant local recurrences in the renal remnant. Based on previously reported results of total nephrectomy for renal cell carcinoma with venous involvement and the morbidity associated with renal replacement therapy, we believe that a nephron-sparing operation is a viable option in the management of these patients.
