[目的]探讨中山市1970～2007年食管癌发病病理构成及其趋势,为食管癌防治提供科学依据。[方法]收集、整理中山市1970～2007年肿瘤登记资料中的食管癌发病资料,统计分析其不同病理类型的发病数、构成及其趋势等指标。[结果]1970～2007年中山市男性与男女性合计食管癌发病持续明显上升,但1990～2007年中山市男、女性食管鳞癌和腺癌发病构成相对稳定。鳞癌一直是中山市食管癌发病的主要病理类型,占同期食管癌发病总数的70.55%,腺癌仅占2.66%。[结论]1970～2007年中山市食管癌发病以鳞癌为主,且不同病理类型构成无明显升降趋势,提示中山市食管癌防治应针对男性及鳞癌发病相关因素。
[Objective] To explore the pathological constitution and trend of esophageal cancer from 1970 to 2007 in Zhongshan City, and to provide a scientific basis for the prevention and treatment of esophageal cancer. [Method] The data of esophageal cancer in Zhongshan City from 1970 to 2007 were collected and analyzed. The incidence, composition and trend of esophageal cancer in different pathological types were statistically analyzed. [Results] The incidence of esophageal cancer in males and females in Zhongshan increased steadily from 1970 to 2007, but the incidence of esophageal squamous cell carcinomas and adenocarcinomas was relatively stable between 1990 and 2007 in Zhongshan. Squamous cell carcinoma has always been the main pathological type of esophageal cancer in Zhongshan City, accounting for 70.55% of the total incidence of esophageal cancer in the same period, accounting for only 2.66% of adenocarcinoma. [Conclusion] The incidence of esophageal cancer in Zhongshan from 1970 to 2007 was mainly squamous cell carcinoma with no obvious increase and decrease trend in different pathological types, suggesting that the prevention and treatment of esophageal cancer in Zhongshan should be related to the incidence of male and squamous cell carcinoma.
