摘要
回顾性分析2015年1月-2021年5月该院471例行ESD治疗,术后病理证实为早期胃癌及癌前病变的患者的临床资料。根据患者Hp感染及根除情况分为3组,Hp阳性且根除转阴者为Hp根除成功组,Hp未根除及根除未转阴者为Hp根除失败组,Hp阴性者为Hp阴性组,对3组患者ESD术后MGC的发生情况及其危险因素进行统计分析。
早期胃癌患者ESD术后MGC 39例(8.3%),Kaplan-Meier分析结果显示:Hp根除成功可明显降低早期胃癌ESD术后MGC风险(
胃癌是世界第五大常见肿瘤。消化内镜技术的迅速发展使胃癌可早期被检出,日本内镜检出病例中有50.0%为早期胃癌,我国发达地区早期胃癌诊断率达20.0
回顾性分析2015年1月-2021年5月本院471例行ESD治疗,术后病理证实为早期胃癌及癌前病变的患者的临床资料。根据患者Hp感染及根除情况分为3组,Hp阳性且根除转阴者为Hp根除成功组(n = 139,29.5%),Hp未根除及根除未转阴者为Hp根除失败组(n = 77,16.4%),Hp阴性者为Hp阴性组(n = 255,54.1%)。471例患者中,男353例(75.0%),女118例(25.0%),年龄27~85岁,平均(61.49±8.41)岁。3组患者基线资料比较,差异无统计学意义(P > 0.05),具有可比性。见

纳入标准:①符合ESD手术适应证;②术后病理诊断为早期胃癌或癌前病变;③首次行胃部ESD,且既往无胃部外科手术史;④Hp感染状态明确且相关资料完整;⑤患者知情同意。排除标准:①随访时间 < 1年;②非治愈性切除;③ESD术后1年内追加外科手术或放化疗。本研究获盐城市第一人民医院伦理委员会审核通过(No:IACUC-D2103043),患者及家属均知情同意。
通过医院诊疗系统收集患者临床资料,通过电话随访完善,重点关注术后Hp根除治疗及MGC发生情况,统计数据并进行回顾性分析。早期胃癌患者于ESD术后3、6和12个月复查内镜,往后每年复查内镜。MGC指:早期胃癌治疗1年后的新发病灶,多出现在原发病灶附

本研究中,早期胃癌ESD术后发生MGC 39例(8.3%)。其中,Hp根除成功组9例(9/139,6.5%),Hp根除失败组20例(20/77,26.0%),Hp阴性组10例(10/255,3.9%)。
Kaplan-Meier分析结果显示:Hp根除成功组MGC的发生率明显低于Hp根除失败组(
Hp根除情况、年龄、吸烟史、饮酒史、平坦型和浸润深度比较,差异均有统计学意义(P < 0.05)。见
将单因素分析提示差异有统计学意义的指标纳入Cox多因素分析,结果显示:Hp根除失败(HR^ = 4.884,95%CI:2.170~10.992,P = 0.000)、年龄 ≥ 60岁(HR^ = 1.050,95%CI:1.006~1.096,P = 0.025)和饮酒(HR^ = 3.629,95%CI:1.769~7.444,P = 0.000)为早癌胃癌ESD术后发生MGC的独立危险因素。见

本研究结果显示,相比于Hp根除成功,Hp根除失败患者的MGC风险明显增高(HR^ = 4.884,95%CI:2.170~10.992,P = 0.000),Kaplan-Meier表明:Hp根除成功可降低MGC发生率约19.5%(Hp根除成功组MGC发生率6.5%,Hp根除失败组MGC发生率26.0%),与既往研
本研究中,Cox多因素分析结果显示:年龄 ≥ 60岁(HR^ = 1.050,95%CI:1.006~1.096,P = 0.025)和饮酒(HR^ = 3.629,95%CI:1.769~7.444,P = 0.000)均为早期胃癌ESD术后发生MGC的独立危险因素。既往研
有文
综上所述,Hp持续感染(包括根除失败)、年龄和饮酒是早期胃癌ESD术后发生MGC的独立危险因素,Hp有效根除可明显降低早期胃癌ESD术后MGC发生风险,医师可基于互联网途径加强患者术后管理,以提高患者Hp根除治疗依从性,养成良好的生活习惯。
