Analysis of the incidence of gastric cancer from 2008 to 2013 in Lianyungang city

目的分析连云港市2008—2013年胃癌发病情况及流行病学特点。方法胃癌发病病例来源于连云港市恶性肿瘤登记报告系统,计算连云港市居民胃癌的粗发病率、中国人口标化率(中标率)和年龄别发病率等指标。率的变化趋势采用变化百分比(PC)和年度变化百分比(APC)等指标。结果 2008—2013年连云港市居民胃癌年均粗发病率为22.41/10万,中标率为17.11/10万,发病率呈下降趋势(PC为-14.52%,APC为-3.75%,P<0.05)。胃癌发病率随年龄增长而上升,55岁后呈现明显增长趋势,在75~79岁年龄组达到高峰。结论当前连云港市胃癌发病率呈下降趋势,但仍需加强监测以探究其长期变化趋势。

Objective To describe the prevalence and epidemic characteristics of gastric cancer incidence in Lianyungang city from 2008 to 2013. Methods Based on data from Lianyungang municipal cancer registry system, crude incidence, China standardized incidence and age--standardized incidence were calculated. Trend of gastric cancer incidence were estimated by in- dices such as percent change（PC）and annual percentage change（APC）. Results From 2008 to 2013 in Lianyungang, the an- nual average crude incidence of gastric cancer was 22.41/10s , the China standardized incidence was 17.11/105 , demonstrating descending trend（PC=- 14.52% ,APC=- 3.75% ,P〈0. 05）. The gastric cancer incidence increased with age , showing a sig- nificant ascending trend after 55 years old. The incidence achieved peak at group of with age of 75-79 years old.
