title: [Epidemiologic investigation on incidences of urological malignant tumors for 10 years in eastern part of Yamaguchi prefecture].
abstract: OBJECTIVE
  In Japan, there is not enough information regarding the incidences of cancer, especially in the field of urology. In order to investigate the accurate occurrence of urological malignant tumors, an epidemiologic study was conducted in the eastern part of Yamaguchi prefecture over a period of 10 years.
  
  
  METHODS
  The target areas for this study were 8 cities (Yamaguchi city, Hofu city, Shin-nanyo city, Tokuyama city, Kudamatsu city, Hikari city, Yanai city and Iwakuni city), and 7 districts (Oshima Gun, Kuga Gun, Kumage Gun, Tsuno Gun, Saba Gun, Abu Gun and Yoshiki Gun) in eastern Yamaguchi prefecture. The investigation period was 10 years: i.e. 1994-2003. Urological malignant tumors in this study were bladder cancer, tumors of the renal pelvis and ureter, renal cell carcinoma, prostatic carcinoma and testicular tumor.
  
  
  RESULTS
  Age-adjusted incidence rates for bladder cancer per 100,000 per year by world population from 1994 to 2003 were 11.26-15.88 for male and 1.91-3.15 for female. The age-adjusted incidence rates for prostatic carcinoma were 10.57-41.78. The age-adjusted incidence rates for tumors of the renal pelvis and ureter were 0.76-1.81, for renal cell carcinoma 1.85-2.68 and for testicular tumor 1.85-2.68.
