[Prognostic-factor-related survival in a series of patients with renal cell carcinoma].

Objectives: To analyze the survival rate in a series of patients with the diagnosis of renal cell carcinoma over a 19 year period based on prognostic factors usually employed in clinical practice.

Methods: Retrospective study of 259 consecutive patients with the diagnosis of renal cell carcinoma undergoing surgery in our department between 1988 and 2006. From clinical, pathological, and follow-up data we performed a survival study comparing the impact of usual prognostic factors: stage, tumor size, nuclear grade, etc.

Results: 264 surgical procedures were performed in 259 patients, with a mean age of 6 1.91 yr. The most frequent way of diagnosis was incidental finding (52.12% of the cases); radical nephrectomy was performed in 72.97% of the cases in comparison with 26.25% partial nephrectomies. Clear cell carcinoma was the most frequent histological diagnosis (69.88%). Patients with clear cell carcinoma, symptomatic tumors, bigger size, and greater Fuhrman nuclear grade presented worse survivals, mainly in tumors with stage >pT3a. The presence of involved lymph nodes or distant metastases is associated with a much lower cancer-specific survival. Global five-year cancer-specific survival was over 80%.

Conclusions: The classical prognostic factors used to predict survival in renal cancer are still useful, mainly pathological stage pT. We observed a better survival in comparison with older series, but this kind of tumors continue generating important morbidity-mortality.
