title: Oncological outcomes of renal pelvic and ureteral cancer patients registered in 2005: the first large population report from the Cancer Registration Committee of the Japanese Urological Association.
abstract: OBJECTIVE
  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.
