OBJECTIVE: To analyze the survival and the main prognostic factors in @entity1 with @entity1606 of the upper urinary tract. METHODS: From 1983 to 1996, we treated 50 @entity1 with @entity1606 of the upper urinary tract. Treatment was basically conservative except in those cases whose @entity5 stage or grade required a radical approach. Grading and staging were performed according to the 1992 TNM classification. Eighteen @entity1 had died at one year mean follow-up., At the time the study was completed (June, 1997), 32 @entity1 were alive with a mean follow-up of 4.9 years. Disease-free survival, overall and specific survival were analyzed according to sex, age, association with @entity150 , localization, type of treatment, @entity5 size, number, histological grade and stage. RESULTS: The male-to-female ratio was 5:1. @entity1 mean age was 65.7 years. Association with @entity150 was observed in 50%. Treatment was conservative in 40% and radical in 60%. The five- and ten-year disease-free survival rates were 69%, overall survival 61% and specific survival 71%. The univariate analysis showed the following to be unfavorable prognostic factors for survival: renal vs @entity5 , radical vs conservative treatment, high grade and stage @entity5 . The association of @entity189 in situ with other @entity5 of the upper urinary tract was also found to be an unfavorable factor for disease-free survival. The multivariate analysis associated T4 and G3 @entity5 with poor prognosis. CONCLUSIONS: @entity1606 of the upper urinary tract was associated with @entity150 in 50% of the cases. Low grade stage @entity5 demonstrated a high survival rate, therefore conservative treatment should be the first approach. High grade/ stage @entity5 were found to be unfavorable prognostic factors for survival.
