2011-2013年寿光市胃癌流行趋势调查

Epidemiological Survey of Gastric Cancer in Shouguang City from 2011 to 2013

目的：研究2011-2013年寿光市胃癌发病状况,分析胃癌恶性程度的相关因素。方法：选择山东省慢性病检测信息系统及本院内镜室工作站病理确诊的胃癌患者共407例作为研究对象。按照地下水盐碱度将本市分为南部地区（非盐碱地）和北部地区（盐碱地）;按照病理类型将胃癌分为高恶性程度和低恶性程度。分析判断性别、年龄、盐碱地环境与胃癌恶性程度的相关性。结果：（1）407名患者中,以男性居多,占75.4%（307例）,女性24.6%（100例）,平均年龄64.75岁（21~90岁）,男女之比3.07∶1,年发病率约为13.3/10万;（2）男性高恶性程度比例低于女性,60岁以上患者高恶性程度比例低于60岁以下患者,北部地区高恶性程度比例明显高于南部地区,比较差异均有统计学意义（P〈0.05）。结论：（1）本市胃癌发病率男性高于女性;（2）女性、中青年人、北部盐碱地区患者更容易患恶性程度高的胃癌。

Objective： To investigate the incidence status of gastric cancer in the population of Shouguang city from 2011 to 2013, to analyse the factors associated with the malignant degree of gastric cancer.Method： 407 gastric cancer patients from the chronic disease detection information system of Shandong and the endoscopy room workstation of our hospital who were diagnosed by pathology were selected as the research objects.Shouguang city was divided into the northern area （ saline-alkali soil ） and the southern area （ not saline-alkali soil ） according to the alkalinity of groundwater.Gastric cancer was divided into the high malignancy and the low malignancy according to the pathological type.The correlations between the malignant degree of gastric cancer and sex, age, saline environment were analyzed.Result： （ 1 ） Among the 407 patients, the majority was male, male and female accounted for 75.4% （ 307 cases ） and 24.6% （ 100 cases ） respectively.Their average age was 64.75 years old （ 21 to 90 years old ）, the ratio between male and female was 3.07： 1.The annual incidence rate is about 13.3/10 million. （ 2 ） The ratio of high malignant degree in the male was lower than that in the female, the ratio of high malignant degree in patients who were more than 60 years old was lower than that in patients who were less than 60 years old, the ratio of high malignant degree in the northern area was higher than that in the southern area, the differences were all statistically significant （ P〈0.05 ） Conclusion： （ 1 ） Male has a higher incidence rate of gastric cancer than female in Shougnang city. （ 2 ） Female, middle-young people and people in the north saline area are more likely to suffer from gastric cancer of high malignant.
