    Abstract:
    OBJECTIVE: To identify certain prognostic factors of renal cell carcinoma in a retrospective series of 233 patients. PATIENTS AND METHODS: 233 patients (162 males and 71 females with a mean age of 60 years) were operated for renal cell carcinoma between January 1980 and December 1991. sith a mean follow-up of 41.7 months. Statistical analysis was performed according to the Kaplan-Meier method for survival curves, according to the Mantel-Cox model for univariate or multivariate analysis and according to Student's t test and Chi-square test for comparison of quantitative and qualitative variables. RESULTS: The operative and global mortality was 2.2% and 28%, respectively. The following prognostic factors were identified: visceral metastases (p = 0.0001), lymph node invasion (p = 0.001), symptomatic nature of the tumour (p = 0.0004), local pathological stage (p = 0.0001) and nuclear grade (p = 0.0001). Multivariate analysis showed that the first 3 factors were the most pejorative (relative risk (RR) = 6.7, 4.6, and 1.7, respectively). Venous invation, multifocal tumours, and cell type were not studied in our series. CONCLUSION: This study confirmed that metastases, lymph node invasion and symptomatic tumours were the most pejorative prognostic factors.
