Incidence and long-term prognosis of papillary renal cell carcinoma.

Objectives: Papillary renal cell carcinoma (pRCC) represents the largest subgroup of non-clear-cell kidney cancer. In this study, we assessed tumour characteristics and long-term prognosis of patients with pRCC in comparison with conventional clear-cell cancer (ccRCC).

Methods: We evaluated 744 patients who had undergone renal surgery for RCC between 1990 and 2005.
