[目的]探讨中山市1970~2009年胃癌发病概况及规律,为中山市胃癌防治提供科学依据。[方法]收集1970~2009年中山市胃癌发病资料,计算其发病例数、发病粗率、中国标化发病率(中标率)与世界标化发病率(世标率)等指标。[结果]1970~2009年中山市男、女性与男女合计胃癌世标率分别为11.01/10万、5.00/10万和7.79/10万,呈先升后相对稳定的趋势,总体无明显升降趋势(P>0.05)。1988~2009年中山市男性和男女合计贲门癌世标率均呈上升趋势(P<0.05)。中山市男性胃癌发病率是女性的2.2倍,男、女不同年龄发病率有所不同,但不同时段胃癌年龄别发病模式基本相同。[结论]中山市胃癌发病水平处于国内较低水平,且相对稳定,但应加强贲门癌的防治。
[Objective] To investigate the general situation and regularity of gastric cancer incidence in Zhongshan City from 1970 to 2009, and to provide a scientific basis for prevention and treatment of gastric cancer in Zhongshan City. [Methods] The incidence of gastric cancer in Zhongshan was collected from 1970 to 2009, and the incidence of gastric cancer was calculated. The incidence of cases, the crude incidence rate, the incidence rate of standardization in China (the successful rate) and the world standardization rate (World standard rate) were calculated. [Results] The total rates of gastric mucosa of men, women and men in Zhongshan from 1970 to 2009 were 11.01 / 100000, 5.00 / 100000 and 7.79 / 100000, respectively, which showed a relatively stable trend after first rising but no obvious trend of ascending and descending (P> 0.05). From 1988 to 2009, Zhongshan City, men and women combined cardia cancer world standard rates showed an upward trend (P <0.05). Zhongshan City, the incidence of gastric cancer in men is 2.2 times that of women, men and women of different ages have different rates of incidence, but at different periods of age gastric cancer incidence patterns are basically the same. [Conclusion] The incidence of gastric cancer in Zhongshan is at a relatively low level in China, and is relatively stable. However, the prevention and treatment of gastric cardia cancer should be strengthened.
