Renal cell carcinoma of extraordinarily large size: a case report.

ABSTRACT

One of our patients was a 66-year-old woman with a T2 renal cell carcinoma weighing 3900 g. Two years after radical nephrectomy the woman was alive and well. A survey of Japanese medical literature revealed that patients with renal cell carcinomas weighing more than 2000 g have an unexpectedly favorable prognosis with a 5-year survival rate of 76.9%.
