The aim of this study was to investigate recent characteristics and alterations of upper @entity3484 based on experience at a single institution over the past decade. Ninety-nine @entity1 with @entity703 resected at the Jikei University Hospital from January 1991 through December 2000 were retrospectively analyzed. Cancer-specific survival by pathologic stage, grade, and various clinical parameters were calculated by the Kaplan-Meier method. Prognostic factors for survival were examined with univariate and multivariate analysis. Cox regression analysis was used for multivariate analysis. Twenty-eight percent of @entity5 had been detected incidentally without having caused any symptoms. The overall 3-year and 5-year @entity5 -specific survival rates were 78% and 70%, respectively. The 5-year survival rate was 100% in @entity1 with G1 @entity5 and 38% in those with G3 @entity5 . The 5-year survival rate was significantly higher in @entity1 with @entity5 of lower grade (p = 0.0089), and was also higher in @entity1 with @entity5 of stage @entity2558 or lower than in @entity1 with @entity5 of stage pT2 and higher (p = 0.0038). The survival of @entity1 with recurrence in the bladder was significantly longer than that of @entity1 with recurrence in other organs. Multivariate analysis indicated that @entity1 age and pT were the most important prognostic factors, followed by the presence of symptoms at diagnosis. The incidence of @entity3484 is increasing at institutions in Japan. We conclude that the @entity5 grade and stage still have classical predictive value, but that the presence of symptoms at the time of diagnosis is also an important prognostic factor.
