慢性萎缩性胃炎、胃粘膜上皮不典型增生与胃癌的相关性研究
STUDY ON RELATIONSHIP BETWEEN CHRONIC ATROPHIC GASTRITIS,EPITHELIAL HYPERPLASIA OF GASTRIC MUCOSA AND MALIGNANT CHANGE
【摘要】 研究慢性萎缩性胃炎(CAG)、胃粘膜上皮不典型增生(ATP)与胃癌的相关性。方法:所有350例中~重度CAG患者均经内镜活检病理确诊,按队列研究,病例组160例系CAG伴中~重度ATP患者,对照组190例则为单纯CAG患者,经1~9年(平均5.5年)的内镜和活检病理随访,观察两组癌变率。结果:共发生胃癌29例,其中病例组癌变率16.2%(26/160),对照组1.6%(3/190)(RR=10.29,P<0.001),与对照组比较,伴中度ATP癌变率7.5%(7/93)(RR=4.76,P<0.05),伴重度ATP癌变率28.4%(19/67)(RR=17.96,P<0.001)。结论:CAG、胃粘膜上皮ATP均与胃癌相关,当两者合并存在时,较单纯CAG癌变危险性增加10倍之多,且CAG伴ATP程度越重,癌变危险性越大
【Abstract】 350 patients with moderate to severe chronic atrophic gastritis(CAG) underwent gastroscopic and histopathologic examinations to estimate the relationship between CAG±atypical epithelial hyperplasia(ATP) and malignant alteration.After “the factorcontrol study”160 cases with CAG+ATP entered the test group,the rest,190 cases with simple CAG,as control.During the followup periods of 1~9 years (mean 55 years),29 gastric cancers were identified.The incidence of malignant change was 163%(26/160) with test group and 16%(3/190) in the control respectively (RR=1029,P<0001)The incidence of gastric carcinoma in cases with CAG+moderate ATP was 75%(7/93),(RR=476,P<005);that with CAG+severe ATP increased to 284%(19/67),(RR=1796,P<0001)Both CAG and ATP correlated with gastric cancer,while the risk of malignant change augmented in CAG with ATP than that without.The severer the CAG and ATP was,the higher the risk would be.
