    Abstract:
    BACKGROUND: Management of malignant renal tumors involving the inferior vena cava (IVC) depends on tumor extension within the cava. METHODS: Of 295 patients treated for renal cancer, propagation of tumor mass through the renal vein to IVC was seen in 22 (7%) patients. Cephalad extension of the tumor was suprarenal: infrahepatic in 12, retrohepatic in 6, and within the right atrium in 4 patients. All patients had radical nephrectomy, cavotomy, and complete resection of tumors except 1 with diffuse peritoneal metastasis. RESULTS: Twenty-one patients had curative resections. No operative deaths and no instances of pulmonary embolism or exsanguination occurred. Seventeen patients were alive at 2 years and 12 at 5 years, resulting in 77% and 55% survival rates, respectively. CONCLUSIONS: An aggressive approach for vena cava involvement from malignant renal neoplasms resulted in prevention of tumor embolus, minimization of blood loss, and maintenance of venous return to the heart.
