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.
