Vena caval resection in bulky metastatic germ cell tumors.

We describe the operative management and followup of vena caval resection in 12 patients with thrombosis of the inferior vena cava secondary to bulky metastatic (stage B3 or IIC) germ cell tumors. All patients received induction chemotherapy (10 platinum-based) followed by retroperitoneal lymph node dissection. The inferior vena cava was resected from just below the renal veins to the bifurcation of the iliac veins. Complete resection of retroperitoneal disease was accomplished in all patients. Five patients had postoperative complications, including 2 small bowel obstructions, 1 prolonged ileus and 2 persistent lymphatic leaks. Mean hospital stay was 37 days (range 27 to 49 days) versus 12 days (range 8 to 16 days) for noncomplicated recoveries. No long-term sequelae related to the vena caval resection have occurred with followup of 24 to 80 months. Seven patients are without disease, with a mean followup of 36 months (range 24 to 60 months). We conclude that en bloc vena caval resection for thrombosis of the vena cava allows for complete resection and simplifies the procedure with acceptable morbidity.
