title: [A clinical study of renal pelvic and ureteral cancer].
abstract: We investigated the clinicopathological features of 52 patients with transitional cell carcinoma of renal pelvic and/or ureter who underwent surgical treatment at Tokyo Medical University Hachioji Medical Center from April, 1992 to June, 2005. The patitents consisted of 38 males and 14 females, ranging from 29 to 86 years old with a median age of 68 years old. The mean follow-up period was 39 months. Pathologicaly, 32 cases were less than pT2 and 20 cases were pT3. Findings of lymphatic and venous invasion were present in 10 and 8 cases, respectively. The infiltration pattern (INF) of gamma was observed in 9 cases. The overall cause-specific survival rate was 95.8% at 1 year, 87.7% at 3 years and 80.6% at 5 years, respectively. According to univariate analysis, the high stage of tumor, the presence of lymphatic and/or venous invasion, the inclusion of infiltration pattern of gamma and positive reginonal lymph nodes indicated a significantly poor prognosis. On the other hand, multivariate analysis using Cox proportional hazards regression revealed the presence of infiltration pattern of gamma as the most significant predictor of survival.
