Both sulfomucin-type intestinal metaplasia (ie, types II and III intestinal metaplasia, colonic-type intestinal metaplasia) and gastritis in Operative Link for Gastritis Assessment stages III and IV are associated with an increased risk of intestinal-type gastric cancer. This study aimed to verify the hypothesis that gastritis in Operative Link for Gastritis Assessment stages III and IV (both consistently associated with an increased cancer risk) is associated per se with types II and III intestinal metaplasia. Two hundred consecutive cases of atrophic gastritis (Operative Link for Gastritis Assessment stages I, II, III, and IV) were considered (50 cases for each stage). All cases were stained with high iron diamine, and intestinal metaplasia was subtyped accordingly (type I [ie, small-intestinal type] and types II and III). Helicobacter pylori status was also considered, distinguishing H pylori-positive versus H pylori-negative versus H pylori-eradicated patients. A significant association was found between intestinal metaplasia subtype and the Operative Link for Gastritis Assessment stage of gastritis (the higher the stage, the more the colonic-type of intestinal metaplasia, and vice versa; Wilcoxon, P = .001). The strength of the association between Operative Link for Gastritis Assessment stages and the 3 intestinal metaplasia subtypes was confirmed by logistic regression analysis (P < .001; odds ratio, 4.84; 95% confidence interval, 2.97-7.88). Intestinal metaplasia subtyping also correlated with the patient's age (Kruskal-Wallis, P = .001) and H pylori status (Fisher exact, P < .001). Operative Link for Gastritis Assessment staging incorporates the prognostic message obtainable from histochemical gastric mucin subtyping.
肠型化生(即 II 型和 III 型肠化生、结肠型肠化生)和 OperaLink 胃炎评估(Operative Link for Gastritis Assessment,OLGA)分期 III 和 IV 的胃炎均与肠型胃癌风险增加相关。本研究旨在验证假设,即 OperaLink 胃炎评估分期 III 和 IV(均与癌症风险增加相关)本身与 II 型和 III 型肠化生相关。考虑了 200 例连续的萎缩性胃炎病例(Operative Link for Gastritis Assessment 分期 I、II、III 和 IV,每个分期 50 例)。所有病例均用高铁二胺染色,并相应地对肠化生进行亚型分类(I 型[即小肠型]和 II 型和 III 型)。还考虑了幽门螺杆菌状态,区分 H. pylori 阳性、H. pylori 阴性和 H. pylori 根除患者。肠化生亚型与胃炎 OperaLink 胃炎评估分期之间存在显著相关性(分期越高,结肠型肠化生越多,反之亦然;Wilcoxon,P =.001)。逻辑回归分析证实了 OperaLink 胃炎评估分期与 3 种肠化生亚型之间的关联强度(P <.001;比值比,4.84;95%置信区间,2.97-7.88)。肠化生亚型也与患者年龄(Kruskal-Wallis,P =.001)和 H. pylori 状态(Fisher 精确检验,P <.001)相关。OperaLink 胃炎评估分期纳入了从组织化学胃黏蛋白亚型获得的预后信息。
