居民生活方式与胃癌的相关性研究

Correlation between Residents’ Lifestyle and Gastric Cancer

胃癌是发生于胃粘膜上皮细胞最常见的恶性肿瘤,在癌症病死率中位居第二位,其发病具有明显的地区差异性,我国农村人群胃癌发生率、病死率均高于城市人群,胃癌5年生存率亦是农村低于城市,严重威胁我国居民的生活质量和身体健康。胃癌的发生是多因素、多步骤进行性的过程。有研究证实幽门螺杆菌感染、进食高盐、霉变食物、油炸食物等行为因素是导致胃癌的高风险因素,因此早期预防、早期筛检是降低胃癌发生率的关键措施。本文就居民饮食及生活习惯与胃癌的关系作一综述,旨在为胃癌一级预防提供参考。

Gastric cancer is the most common malignant tumor that occurs in gastric epithelial cells.It ranks second in cancer mortality,and its pathogenesis has obvious regional differences.The incidence and mortality of gastric cancer in rural population in China are higher than those in urban population.The 5-year survival rate is also lower than that in rural areas,which seriously threatens the quality of life and physical health of Chinese residents.The occurrence of gastric cancer is a multi-factor,multi-step progressive process.Studies have confirmed that Helicobacter pylori infection,eating high salt,mildew food,fried food and other behavioral factors are high risk factors for gastric cancer,so early prevention and early screening are the key measures to reduce the incidence of gastric cancer.This article reviews the relationship between dietary and living habits and gastric cancer,and aims to provide a reference for primary prevention of gastric cancer.
