Long-term Results of Resection of Renal Cell Cancer with Extension into Inferior Vena Cava

From July 2, 1971 to April 1, 1985, 47 patients (median age 63 years) with renal cell cancer extending into the renal vein or inferior vena cava were evaluated and treated. Two-thirds of the tumors occurred in men and three-fourths were found in the right kidney. Of the 44 patients operated on 35 had no evidence of preoperative metastatic disease at operation. The patients were divided into ideal, favorable and unfavorable subgroups. The adjusted 5 and 10-year survival rates in the former 2 groups (32 patients) were 68.8 and 60.2 per cent, respectively. In contrast, 12 patients with nodal involvement or metastases had an adjusted median survival time of 1.2 years with no survival extending beyond 4.8 years. We believe that an extended operation for renal cell cancer with involvement of the vena cava is warranted and provides reasonable long-term survival in properly selected patients.
