目的了解2014—2018年丽水市居民胃癌发病和死亡特征,为制定胃癌防制策略提供依据.方法通过浙江省慢性病监测信息管理系统收集2014—2018年丽水市居民胃癌发病、死亡资料,分析发病率、死亡率等指标;计算年度变化百分比(APC)分析胃癌发病和死亡变化趋势.结果 2014—2018年丽水市确诊新发胃癌5650例,年平均发病率为44.77/10万,标化率为26.93/10万,发病率的APC值为-0.79%,呈逐年下降趋势(P<0.05);胃癌死亡3205例,年平均死亡率为25.39/10万,标化率为14.21/10万,死亡率的APC值为-4.61%,未见明显变化趋势(P>0.05).男性胃癌标化发病率和标化死亡率分别为34.77/10万和18.35/10万,均高于女性的16.77/10万和8.52/10万.农村居民胃癌标化发病率和标化死亡率分别为46.07/10万和26.11/10万,均高于城市居民的38.49/10万和22.02/10万.居民胃癌发病率、死亡率均在15岁后随年龄增加呈上升趋势,80岁~组达到峰值.结论 2014—2018年丽水市胃癌发病率和死亡率处于较高水平,胃癌发病率呈下降趋势;胃癌发病率和死亡率均为男性高于女性,农村高于城市.

Objective To learn the characteristics of gastric cancer incidence and mortality in Lishui from 2014 to 2018,and to provide basis for prevention and control strategies for gastric cancer. Methods The data of gastric cancer in Lishui from 2014 to2018 was collected from Zhejiang Chronic Disease Surveillance Information Management System. The incidence and mortality rates of gastric cancer were calculated,and the trend of them was evaluated by annual percentage change(APC). Results The crude incidence rate of gastric cancer in Lishui was 44.77/100 000(5 650 cases) and the standardized one was 26.93/100 000. From2014 to 2018,the incidence rates of gastric cancer showed a decreasing trend(APC=-0.79%,P<0.05). The crude mortality rate of gastric cancer in Lishui was 25.39/100 000(3 205 cases) and the standardized one was 14.21/100 000. From 2014 to2018,the mortality rates of gastric cancer were stable(APC=-4.61%,P>0.05). The standardized incidence and mortality rates of gastric cancer in males were 34.77/100 000 and 18.35/100 000,which were higher than 16.77/100 000 and 8.52/100 000 in females(P<0.05). The standardized incidence and mortality rates of gastric cancer in rural residents were 46.07/100 000 and 26.11/100 000,which were higher than 38.49/100 000 and 22.02/100 000 in urban residents. The incidence and mortality rates increased with age after 15 years old, and reached the peak at the age group of 80-84 years old. Conclusion The incidence and mortality of gastric cancer in Lishui from 2014 to 2018 were at a high level,which were higher in males than in females and were higher in rural than in urban areas;while the incidence had a downward trend.
