我国为胃癌高发国家之一,其死亡率占所有癌肿的首位。胃癌高发地区慢性萎缩性胃炎在成年人群中发生率亦高(50～60%),这与世界上胃癌高发国家报道相似。我国曾报道分析胃癌切除的胃标本伴发慢性萎缩性胃炎病变与肠化者达90%左右,其中以分化型胃癌者尤为明显。由于慢性萎缩性胃炎与胃癌的发生率呈明显正相关,而引起关注,重点是要弄清慢性 China is one of the countries with high incidence of gastric cancer, and its mortality rate is the highest among all cancers. The incidence of chronic atrophic gastritis in high incidence areas of gastric cancer is also high in adults (50 to 60%), which is similar to the high incidence of gastric cancer in the world. In China, it has been reported that gastric specimens with gastrectomy associated with chronic atrophic gastritis lesions and intestinal metaplasia are up to 90%, of which differentiated gastric cancer is particularly evident. Because the incidence of chronic atrophic gastritis is positively related to the incidence of gastric cancer, it has attracted attention and the focus is to find out
