Abstract

Objectives: To describe the clinical and pathological characteristics and the outcomes of renal pelvic and ureteral cancer patients diagnosed in 2005 in Japan. Methods: In 2011, data were collected from renal pelvic and ureteral cancer patients diagnosed in 2005. A total of 1509 registered patients from 348 institutions were analyzed. Epidemiology and survival were analyzed based on each cancer location and on cancer multiplicity. Results: The 5-year overall survival of the 1509 patients was estimated at 0.64. Open surgery was carried out in 409 renal pelvic cancer cases (66.9%) and 315 ureteral cancer cases (63.0%). The retroperitoneal approach was common, and lymph node dissection was carried out in approximately one-third of open surgery cases and one-fifth of laparoscopic cases. Approximately 60% of the operated unilateral renal pelvic or ureteral cancer was diagnosed as invasive, and just 14.6% was diagnosed as stage pTa. Distribution of the estimated worst tumor grade was significantly different for renal pelvic cancer and ureteral cancer. Conclusions: This article presents the first large population report of survival data in Japanese renal pelvic and ureteral cancer patients. In comparison with the Japanese bladder cancer database report in 1999-2001 from the Cancer Registration Committee of the Japanese Urological Association, the pathological characteristics of renal pelvic and ureteral cancer were diagnosed as aggressive.
