目的了解2004—2005年四川省居民胃癌死亡特征。方法按ICD-10的标准,对2004—2005年全国第三次死因回顾抽样调查四川省10个调查点居民胃癌死亡率进行分析。结果10个调查点胃癌年均粗死亡率为29.71/10万,标化死亡率22.60/10万,10个调查点胃癌死亡率在9.86/10万～64.22/10万之间,且各调查点间死亡率差别有统计学意义(χ2=918.57,P<0.0001),盐亭县和康定县的胃癌死亡率分别居第1、2位,标化死亡率分别为47.30/10万、40.21/10万。随着年龄的增大胃癌死亡率呈逐渐增加的趋势(P<0.0001);男、女性胃癌标化死亡率分别为28.88/10万、15.72/10万,男性高于女性(χ2=264.87,P<0.0001)。结论四川省居民胃癌死亡率较高,盐亭县和康定县达到国家胃癌高发县(区)的标准,胃癌是威胁中老年人健康的主要恶性肿瘤。
Objective To understand the characteristics of gastric cancer death in Sichuan Province from 2004 to 2005. Methods According to the standard of ICD-10, the mortality rate of gastric cancer in residents from 10 survey sites in Sichuan Province was analyzed from a retrospective sampling survey of the third national cause of death in 2004-2005. Results The average annual crude death rate of gastric cancer was 29.71 / 100 000 in 10 surveys, with a standardized mortality rate of 22.60 / 100 000. The gastric cancer death rates in 10 investigated sites ranged from 9.86 / 100 000 to 64.22 / 100 000, The difference between the two groups was statistically significant (χ2 = 918.57, P <0.0001). The mortality rates of gastric cancer in Yanting and Kangding ranked No.1 and No.2, respectively. The standardized death rates were 47.30 / 100000 and 40.21 / 10 Million The mortality of gastric cancer increased gradually with the increase of age (P <0.0001). The standardized mortality rates of gastric cancer in male and female were 28.88 / 100000 and 15.72 / 100000, respectively, higher in males than in females (χ2 = 264.87, P <0.0001). Conclusion The mortality rate of gastric cancer in Sichuan Province is high. Yanting County and Kangding County have reached the national standard of high incidence of gastric cancer in the country. Gastric cancer is a major malignant tumor that threatens the health of middle-aged and elderly people.
