萎缩性胃炎与胃癌的关系密切已引起普遍重视。在普查中有人对胃粘膜进行的检查表明胃癌高发区萎缩性胃炎的发病率比低发区明显要高,而且高发区人群中慢性萎缩性胃炎的检出率与胃癌的检出率有着平行的关系。在大体病理研究中证实萎缩性胃炎存在于70～97％的胃癌标本中。本省系胃癌高发区之一,本文特对兰州地区萎缩性胃炎500例作如下分析报道。一、检查对象:本文报道受查对象均为77年以来门诊和住院的消化科病人,其中男331人、女169人,男:女=1.96:1,男约为女之2倍,年龄20～79岁。二、诊断标准:本文诊断标准均以胃镜肉眼或活检病理证实。胃镜下以粘膜典
The close relationship between atrophic gastritis and gastric cancer has attracted widespread attention. In the census, examination of gastric mucosa showed that the incidence of atrophic gastritis in high-incidence areas of gastric cancer was significantly higher than that in low-prevalence areas, and the detection rate of chronic atrophic gastritis in populations with high incidence was parallel to the detection rate of gastric cancer. relationship. In gross pathological studies it was confirmed that atrophic gastritis is present in 70 to 97% of gastric cancer specimens. This province is one of the high-incidence areas of gastric cancer. This article specifically analyzes 500 cases of atrophic gastritis in Lanzhou as follows. I. Object of examination: This article reports that the subjects under investigation are both outpatients and inpatients of gastroenterology since 77 years ago. Among them, 331 males and 169 females, male: female = 1.96:1, male is about 2 times female, age 20 ~ 79 years old. Second, the diagnostic criteria: The diagnostic criteria of this article were confirmed by gastroscopy or biopsy pathology. Endoscopic mucosal cannula
