In order to evaluate the prognostic factors of @entity1358 ( @entity1358 ), a retrospective study was carried out on 215 @entity1 (150 @entity1 , 65 @entity1 ) who had undergone surgical treatment from March 1979 to December 1986. The average age of the @entity1 was 58 years (ranging from 15 to 85 years). The ratios of survival to @entity5 stage and grade, as well as to nodal and venous involvement, distant metastases at the time of diagnosis (as @entity2802 classification) were evaluated by means of the actuarial method (life table). Corrected 5-year survival rates for stage T1-T4 were 100, 81, 68.9 and 0%, respectively. Grade 1 and grade 2 @entity5 had a 5-year survival rate of 66.5 and 52.8%, respectively; grade 3 had a 3-year survival rate of 46.5%. Nodal involvement at the time of diagnosis had a prediction value for the 3- and 5-year survival rate of 39.8 and 34.5%, respectively. Metastases at time of diagnosis had a 14.1% prediction value for a 3-year survival rate. @entity5 extension to the vena cava (21 @entity1 ) affected survival in a significant way (55.8% at 3 years). A definite tendency towards lower stage and grade was observed in incidentally diagnosed @entity1358 (11%). In conclusion, stage, grade, nodal and venous involvement as well as metastases at the time of diagnosis have a significant prognostic value in @entity1358 . These data and the lack of early diagnostic methods for @entity1358 suggest the routine use of renal ultrasonography in clinically asymptomatic @entity1 during examination for suspected @entity1625 and in high-risk @entity1 ( @entity280 ).
