BACKGROUND AND METHODS: Bipedal lymphography and percutaneous @entity400 ( @entity400 ) of pelvic lymph node was done in 200 @entity1 with @entity150 . RESULTS: A diagnosis of @entity3 to the pelvic lymph node was obtained by this method in 34 @entity1 . Of these 34 @entity1 , only 12 (35%) were positive or suspected of having pelvic lymph node @entity3 by computed tomography. Sixteen @entity1 (47%) had unequivocally positive or highly suspicious lymphogram and 18 @entity1 (53%) had normal lymphogram. Seventy-eight cases, including eight @entity400 -positive cases, were treated by radical cystectomy and regional lymph node dissection. Sensitivity, specificity, positive predictive value and negative predictive value of @entity400 were 57, 100, 100 and 91%, respectively. Thirteen @entity400 @entity1 could be treated by multimodality therapy and evaluated after neoadjuvant therapy by repeated lymphography and @entity400 . All were changed to N0 by @entity400 after neoadjuvant therapy. In eight @entity1 treated by total cystectomy and lymph node dissection, four had down staged to pN0 but four had one positive node. In five follow-up cases without surgery, one had recurrent pelvic lymph node @entity3 35 months later. Cause-specific survival of these @entity1 was 76% at 5 years and 57% at 8 years. CONCLUSIONS: Pretreatment diagnosis of pelvic lymph node @entity3 and multimodality therapy may improve the prognosis of regional lymph node-positive @entity150 . Because it is difficult to diagnose @entity3121 using @entity400 , radical operation should be performed even if neoadjuvant therapy is effective and down staging is obtained.
