NEJM:幽门螺杆菌根除可大幅降低异时性胃癌风险

研究认为对于早期胃癌患者接受幽门螺杆菌根除可大幅降低异时性胃癌发生率并改善胃体萎缩症状

仅限于胃黏膜或粘膜下层的早期胃癌患者常存在粘膜腺组织(腺体萎缩)病变,并伴有继发性胃癌风险升高,目前幽门螺杆菌根除对早期胃癌患者组织学改善和异时性胃癌的长期防治效果仍不清楚。

近日研究人员开展前瞻性、双盲、安慰剂对照随机试验,470名因早期胃癌或高级别腺瘤接受内镜下切除患者参与,患者随机接受抗生素幽门螺杆菌根除或安慰剂。主要终点包括异时性胃癌的发生率,以及胃腺体萎缩改善。

总计396名患者接受意向分析,其中治疗组194人,安慰剂组202人。平均随访5.9年,治疗组14人(7.2%)以及安慰剂组27人(13.4%)发展为胃癌(HR,0.50; 95% CI, 0.26-0.94; P=0.03)。对327名患者进行组织学分析发现,48.4%的治疗组以及15.0%的对照组患者存在胃腺体萎缩改善(P<0.001)。未发生严重的不良事件,治疗组中度不良事件率较高(42.0% vs. 10.2%, P<0.001)。
