Small Renal Cell Carcinoma Associated with Inferior Vena Cava Thrombus / 대한비뇨기과학회지

ABSTRACT

Renal cell Carcinoma is an unusual cancer with the propensity to invade not only the renal vein but to propagate into the inferior vena cava(IVC) as a tumor thrombus. No tumor thrombus extending to the IVC was seen in a renal cell carcinoma less than 4.5 cm in the greatest diameter among 431 consecutive patients in the Mayo Clinic from January 1976 to January 1992. The present case was a 3.5 cm in size small renal cell carcinoma on the right upper pole which had a tumor thrombus which extended to the inferior vena cava.
