目的探讨上海市松江区1988—2012年胃癌发病情况及规律,为制定松江区胃癌防治策略提供科学依据。方法收集1988—2012年松江区胃癌发病资料,描述其性别、年龄分布,运用年度变化百分比(annual percent change,APC)对松江区1988—2012年胃癌发病率的时间趋势进行分析。结果松江区胃癌发病率随年龄增长而增加,男女性发病率均在50岁以后进入加速增长期,男性年龄别发病率增速明显高于女性。结果显示,1988—2012年,松江区胃癌标化发病率总体呈下降趋势,年下降率为3.44%,下降主要出现在1988—2000年。男性发病率下降略快于女性;45~64岁组呈持续下降态势,65~74岁组显著下降出现在1998—2000年。结论松江区胃癌发病率呈逐年下降态势,但随着年龄增长而上升。应加强胃癌相关环境、行为危险因素研究,并在此基础上采取具有针对性的公共卫生预防措施。
Objective To investigate the incidence and patterns of gastric cancer in Songjiang District of Shanghai from 1988 to 2012 and provide scientific evidence for the prevention and treatment of gastric cancer in Songjiang District. Methods The incidence of gastric cancer in Songjiang District from 1988 to 2012 was collected to describe its gender and age distribution. The annual trend of gastric cancer incidence in Songjiang District from 1988 to 2012 was analyzed by annual percent change (APC). Results The incidence of gastric cancer in Songjiang District increased with age. The incidence rates of both men and women entered the accelerated growth stage after the age of 50, and the incidence rate of male age was significantly higher than that of women. The results showed that from 1988 to 2012, Songjiang District, the overall incidence of gastric cancer showed a downward trend, the annual decline was 3.44%, the decline occurred mainly in 1988-2000. Male incidence decreased slightly faster than women; 45 to 64-year-old group continued downward trend, 65-74 year-old group decreased significantly from 1998 to 2000. Conclusion The incidence of gastric cancer in Songjiang District showed a declining trend year by year, but rose with age. Should be strengthened gastric cancer-related environment, behavioral risk factors, and on this basis to take targeted public health preventive measures.
