Time trends of age-standardized rate (ASR) of gallbladder cancer incidence (ICD-10: C23–C24) were compared among 18 selected cancer registries and ethnic/racial groups in East Asia, Europe and the USA. Data source was the Cancer Incidence in Five Continents Vols IV–VIII (years at diagnosis: 1973–77, 1978–82, 1983–87, 1988–92 and 1993–97, respectively). World population was used for age-standardization.
Figure 1 shows time trends of ASR of gallbladder cancer incidence for males. When all the areas including Asia, Europe and the USA were compared, age-adjusted incidence rates (ASRs) of gallbladder cancer were comparatively higher in three Japanese registries (Miyagi,
