Abstract
To understand the current epidemiological characteristics as well as the trends of stomach cancer deaths in China. The data of stomach cancer mortalities in 2004 - 2005, from 158 sampling areas in the Third National Retrospective Sampling Survey of Death Causes in China, were analyzed and compared with the results from previous two national surveys. The crude and age-standardized death rates of stomach cancer were 24.71/100 000 (35 250/142 660 482) and 16.16/100 000, respectively, accounted for 18.19% (35 250/193 841) and ranking third of cancer causes in the national sampling areas of China in 2004 - 2005. Those crude death rate increased by 42.01% while the age-standardized death rate decreased by 8.70% compared to the results in 1973 - 1975 (17.40/100 000 and 17.70/100 000), and both decreased 1.79% and 25.74% from 1990 - 1992 (25.16/100 000 and 21.76/100 000), respectively. For urban residents of the sampling areas, the crude and age-standardized death rates of stomach cancer were 22.98/100 000 (11 005/47 899 806) and 13.63/100 000, accounted for 15.03% (11 005/71 936) of cancer causes in 2004 - 2005, which increased by 18.21% and decreased by 31.16% from 1973 - 1975 (19.44/100 000 and 19.80/100 000), and increased by 18.21% and decreased by 11.15% from 1990 - 1992 (19.44/100 000 and 15.34/100 000), respectively. While for rural residents in the sampling areas, the crude and age-standardized death rates were 25.59/100 000 (24 245/94 760 676) and 17.64/100 000, accounted for 19.89% (24 245/121 905) of cancer causes, both increased by 53.97% and 3.76% from 1973 - 1975 (16.62/100 000 and 17.00/100 000), and both decreased by 5.78% and 27.59% from 1990 - 1992 (27.16/100 000 and 24.36/100 000), respectively. The current stomach cancer is still one of predominant cancers in China. The consistently substantial decreases in age-standardized death rates of stomach cancer might prompt the beneficial impact on reducing the risks for that cancer by the social economical development during recent decades in China.
