An Analysis of Incidence and Mortality of Stomach Cancer in China,2009

[Purpose] To evaluate stomach cancer incidence and mortality in China in 2009. [Methods] On basis of the criteria of data quality from NCCR, data submitted from 104 registries were checked and evaluated. There were 72 registries’ data qualified and accepted for cancer registry annual report in 2009. Descriptive analysis included incidence and mortality stratified by area (urban/rural), gender, age group and cancer site. Chinese population census in 1982 and Segi’s population were used for age-standardized incidence/mortality rates. [Results] The total new stomach cancer incident cases and cancer deaths were 30 949 and 22 120 respectively in 2009. The morphology verified cases accounted for 76.14%. About 2.95% of incident cases only had information from death certifications and mortality/incidence ratio was 0.71. The crude incidence rate of stomach cancer in registration areas was 36.21/105 (49.61/105 for male,22.50/105 for female), age-standardized incidence rates by Chinese standard population (ASR China) and by world standard population (ASR World) were 17.85/105 and 23.93/105 with the cumulative incidence rate (0～74 years old) of 2.94%. The stomach cancer incidence and ASR China were 30.20/105 and 14.15/105 in urban area while in rural area they were 48.57/105 and 26.31/105 respectively. The stomach cancer mortality in Chinese cancer registration areas was 25.88/105 (34.64/105 for male and 16.91/105 for female), ASR China and ASR World were 11.86/105 and 16.38/105 , and the cumulative mortality rate (0～74 years old) was 1.89%. The stomach cancer mortality and ASR China were 21.15/105 and 9.07/105 in urban area, while in rural area they were 35.60/105 and 18.25/105 respectively. [Conclusion] Stomach cancer is one of the major threats to the health of our residents, which is different between urban and rural areas in China. Prevention and treatment should be carried out according to the practical situation.
