title: [An analysis of the prognostic factors in renal-cell carcinoma].
abstract: OBJECTIVE
  The study proposes the analysis of the influence of gross, microscopical and clinical pathoanatomical prognostic factors in the survival of patients with RCC through univariance and multivariance statistical analysis, and its global evaluation as a predictive model.
  
  
  METHODS
  The study involved 218 RCC cases operated on over 20 years, with a mean follow-up of 60 months.
  
  
  CONCLUSIONS
  All prognostic factors studied have a significant influence on the survival. When studied jointly, they include separately and in order of significance the metastatic involvement, mitotic index, cava vein involvement, nuclear grade and sarcomatoid histologic pattern. Also, we confirm that considered jointly they conform a valid predictive model.
