[Results of radical nephrectomy for XXXX . Report 1. Analysis according to the TNM staging system of the general rule for clinical and pathological studies on @entity1358 ].

@entity1 @entity2558 @entity1803 @entity5 @entity1358 @entity3
One hundred and six @entity1 with @entity1358 were treated with radical nephrectomy at our Department between 1970 to December, 1985. A retrospective analysis was performed with TNM staging system of The General Rule for Clinical and Pathological Studies on @entity1358 , which was established by the Japanese Urological Association in 1983. The 5-year survival rate according to pathological @entity5 was 100% for 2 @entity1 in @entity2558 , 67.5% for 58 @entity1 in pT2, 49.5% for 42 @entity1 in @entity1803 , 0% for 4 @entity1 in pT4. Two @entity1 in stage of @entity2558 had no venous involvement, lymph node @entity3 , or distant @entity3 . Twenty two @entity1 had positive venous involvement (21%), 4 (7%) in stage of pT2, 16 (38%) in @entity1803 , 2 (50%) in pT4. Twelve @entity1 had positive lymph nodes (11%), 0 (0%) in stage of pT2, 10 (24%) in @entity1803 , 2 (50%) in pT4. Twenty five @entity1 , (24%) had distant @entity3 at the time of nephrectomy, 8 (14%) in stage of pT2, 15 (38%) in @entity1803 , 2 (50%) in pT4. The 5-year survival of 22 @entity1 with venous involvement, 12 @entity1 with lymph nodes @entity3 , 25 @entity1 with distant @entity3 were 47%, 30%, 39% respectively. No significant difference of 5-year survival between 69% of 48 @entity1 in T1 _ 2VoNoMo (Robson-I) and 76% of 12 @entity1 in T3VoNoMo (Robson-II) were considered to need the establishment of new classification for early stage of @entity1358 . TNM staging system was thought to be better than Robson's Classification for analyzing the unique biological potential of @entity1358 .
