腎盂尿管腫瘍109例について,予後因子に関する臨床病理的検討を行った.深達度,異型度,腫瘍長径,脈管浸潤の有無,浸潤様式,リンパ節転移の有無のいずれも有意な予後因子であると考えられたが,多変量解析では深達度及びリンパ節転移の有無が最も予後に影響を与える因子であったWe investigated the clinicopathological features of 109 patients with urothelial tumors of the renal pelvis and ureter who underwent surgery at four institute from April, 1975 to September, 1997. The patients consisted of 71 males and 38 females, and the mean age was 66.8 years, ranging from 41 to 92 years. Mean followup period was 43 months. The prognostic significance of the pathological factors; pT, Grade, INF, tumor size, pL, pV and pN were evaluated. All these factors affected the survival rates significantly in univariate analysis. Multivariate analysis showed the most influential prognostic factors to be pT and pN.
