    Abstract:
    The objective of this study is to evaluate the prognostic factors and the role of nephrectomy in metastatic renal cell carcinoma. We reviewed 62 cases of metastatic renal cell carcinoma to document the factors influencing survival and to evaluate the role of nephrectomy. Sex and age of patients, size of primary tumor, site and number of metastases, nephrectomy, cell type and grade of tumor and medical treatment were analyzed as prognostic factors. Age and sex, cell type and type of medical treatment cannot be considered reliable predicting factors. However, improved survival was correlated with tumor size < or = 7 cm in diameter, low grade histology, metastasis limited to single organ and removal of the primary tumor. When these parameters were analyzed in a multivariate model, the presence of nephrectomy was the sole significant parameter. We therefore suggest that nephrectomy should be considered in all patients with metastatic renal cell carcinoma, as long as the morbidity of the operation is acceptable.
