[Clinical studies on renal pelvic and ureteral tumors].
OBJECTIVE
We reviewed 77 patients of renal pelvic and ureteral tumor treated at Osaka Police Hospital between 1990 and 2003.


METHODS
The patients consisted of 55 males and 22 females. The median age was 69 years, ranging from 42 to 91 years. Median follow-up period was 42 months.


CONCLUSIONS
The overall 3, 5 and 10-year cause-specific survival rates were 87.9, 75.3%, 75.3%, respectively. Univariate analysis indicated age, tumor location, number, and shape, stage, grade, infiltrating pattern, lymphatic and venous involvement to be significant prognostic factors. Moreover, multivariate analysis with Cox's proportional hazard model revealed lymphatic involvement and tumor number to be independent prognosticators for cause-specific survival.
