Transitional cell carcinoma of the kidney with tumor thrombus into the vena cava.

Transitional cell carcinoma of the upper urinary tract with inferior vena cava tumor thrombus is an unusual entity. We report the 16th such case and review the previous cases in the world literature. Preoperative diagnosis was correct in only 5 of the cases. This type of condition can be easily presumed to be renal cell carcinoma. Fifteen of the cases were managed with radical nephrectomy; 8 patients were managed with partial or complete resection of the vena cava due to adherence of the tumor thrombus to the vessel wall. Overall outcome was poor, with short postoperative survival. Correct preoperative diagnosis, although difficult, could allow more complete preoperative planning or appropriate nonoperative management.
