Analysis of incidence and mortality of stomach cancer in China from 2003 to 2007

Objective: To analyze the incidence and mortality of stomach cancer in China from 2003 to 2007. Methods: The registration data during 2003 to 2007 from 32 cities/ counties were used to estimate stomach cancer incidence and mortality and their changing trends in China. Results: The crude incidence rate of stomach cancer was 33.14/100 000 and the age-standardized rate (ASR) by world population was 23.09/100 000, ranked the second of all new cancer cases during 2003 to 2007 in China. A higher incidence rate was found in the males than in the females. In the same time period, the crude mortality rate of stomach cancer was 24.34/100 000, and the ASR by world population was 16.39/100 000, ranked the third of all cancer deaths, with a higher rate in the males than in the females. The age-specific incidence and mortality rates were increased with increasing age. The differences of ASR in the incidence and the mortality by world population among different regions were found as high as 16.3 and 19.1 folds in the males, and 17.5 and 27.0 folds in the females, respectively. Conclusion: The incidence and mortality of stomach cancer are still high in China from 2003 to 2007. There are substantial variations in the incidence and mortality rates of stomach cancer by age and region. DOI:10.3781/j.issn.1000-7431.2012.02.006
