Analysis of Mortality of Stomach Cancer in China from 1990-1992

OBJECTIVE To assess the impact of stom‘ach cancer on the Chinese population by epidemiological analysis of its distributional mortality.METHODS Data from 1990-1992 on stomach cancer mortality collected by a sampling survey involved one tenth of the total Chinese population.RESULTS The crude mortality rate of stomach cancer in China was 25.2per 10^5 (32.8 per 10^5for males and 17.0 per 10^5 for females), which comprised23.2% of the total cancer deaths from 1990 to 1992, making stomach cancerthe leading cause of cancer death. The stomach cancer mortality rate ofmales was 1.9 times of that of females. The Chinese mortality rates ofstomach cancer adjusted by the world standard population were 40.8 per105 and 18.6 per 105 for males and females, which were 4.2-7.9 (for males)and 3.8-8.0 (for females) times of those in developed countries. Age-adjusted mortality rates of stomach cancer in China have distinctgeographical differences: form the lowest of 2.5 per 10^5 to the highest of153.0 per 10^5 in the 263 selected sites, and 15.3 per 10^5 in urban areas and24.4 per 10^5 in rural areas, a difference of 1.6 times.CONCW$10N The prevention and treatment of stomach cancer in L;n~na,especially in the countryside and the under-developed areas in thenorthwest, should be a long-term focus in preventing of cancers of thedigestive system. Urgent measures for prevention and early detection of stomach cancer should be taken.

Analysis of mortality of stomach cancer in China from 1990–1992

Objective To assess the impact of stomach cancer on the Chinese population by epidemiological analysis of its distributional mortality. Methods Data from 1990–1992 on stomach cancer mortality collected by a sampling survey involved one tenth of the total Chinese population. Results The crude mortality rate of stomach cancer in China was 25.2 per 10⁵ (32.8 per 10⁵ for males and 17.0 per 10⁶ for females), which comprised 23.2% of the total cancer deaths from 1990 to 1992, making stomach cancer the leading cause of cancer death. The stomach cancer mortality rate of males was 1.9 times of that of females. The Chinese mortality rates of stomach cancer adjusted by the world standard population were 40.8 per 10⁵ and 18.6 per 10⁵ for males and females, which were 4.2–7.9 (formales) and 3.8–8.0 (for females) times of those in developed countries. Age adjusted mortality rates of stomach cancer in China have distinct geographical differences: form the lowest of 2.5 per 10⁵ to the highest of 153.0 per 10⁵ in the 263 selected sites, and 15.3 per 10⁵ in urban areas and 24.4 per10⁵ in rural areas, a difference of 1.6 times. Conclusion The prevention and treatment of stomach cancer in China, especially in the countryside and the underdeveloped areas in the northwest, should be a long-term focus in preventing of cancers of the digestive system. Urgent measures for prevention and early detection of stomach cancer should be taken. This work was supported by the National Important Medicine Technology “The Eighth Five-Years” Foundation.
