摘　　要：食管癌在世界癌症发病中占第8位,位居全球癌症死因的第6位。食管癌预后较差,对人类健康的危害严重。我国是食管癌高发国家,也是世界上食管癌新发病例最多的国家。食管癌的组织学类型主要分为食管鳞癌和食管腺癌,从上世纪70代开始许多西方国家的食管鳞癌发病率呈下降趋势,与此相反食管腺癌的发病率迅速增加,成为增长速度最快的恶性肿瘤之一。中国人群食管癌的病理类型以鳞状上皮细胞癌为主,该组织学类型占我国食管癌发病的90%以上。我国食管癌发病率呈明显的地区差异,食管鳞癌和食管腺癌的发病水平、地理分布、时间变化趋势及发病危险因素存在较大差别。本文阐述食管癌发病水平及变化趋势,以期为我国食道癌预防和控制策略制定、实施与效果评估提供基础信息。Esophageal cancer is the eighth most common cancer in the world and is the sixth leading cause of cancer-related death. This disease has a poor prognosis and does serious harm to human health. China has the largest number of ne^yly reported cases of esophageal cancer in the world. The incidence of squamous cell carcinoma in many western countries showed a downward trend since the 1970s. However, the incidence of esophageal adenocarcinoma has increased rapidly and eventually become the fastest-grow- ing malignant tumor in the world, Esophageal squamous cell carcinoma remains the most common esophageal cancer in China and ac- counts for more than 90% of all the esophageal cancer cases in the country. The incidence trend of esophageal cancer significantly dif- fers across various cancer pathological types and geographical regions. This trend offers a helpful reference for developing a preven- tion and control strategy and understanding the incidence level and trend of esophageal cancer.
