摘　　要：目的探讨早期食管癌患者合并斑驳食管的相关危险因素及其与乙醇脱氢酶1B(ADH1B)和乙醛脱氢酶2(ALDH2)基因多态性之间的相关性。方法收集因早期食管癌拟行内镜黏膜下剥离术患者的临床资料并采集血样测定ADH1B和ALDH2的基因分型,依据其碘染后的内镜特征分为斑驳食管组和非斑驳食管组,采用SPSS 27.0对上述资料进行统计学分析。结果共纳入研究对象83例,23例存在斑驳食管,多见于男性、饮酒、吸烟指数≥1000者,多因素分析显示饮酒(OR=6.215,P=0.008)是其独立危险因素。ADH1B和ALDH2基因多态性及其交互作用与斑驳食管无显著相关性,但在饮酒者中,相对于携带ALDH2 GG基因型且每日饮酒量<50 g的患者,携带ALDH2 A等位基因且每日饮酒量≥50 g发生斑驳食管的风险增加了12倍(P=0.045)。结论饮酒是早期食管癌患者合并斑驳食管的独立危险因素,乙醛的蓄积在其发生机制中起着重要作用,携带ALDH2A等位基因者大量饮酒将显著增加斑驳食管的发生风险,对于此类患者应密切内镜随访。Objective To investigate the risk factors associated with the presence of multiple Lugol-voiding lesions(LVLs)in patients with early esophageal cancer and the correlation with alcohol dehy-drogenase 1B(ADH1B)and aldehyde dehydrogenase 2(ALDH2)polymorphisms.Methods Patients who underwent endoscopic submucosal dissection due to early esophageal cancer were divided into group with multiple LVLs and group without multiple LVLs based on their endoscopic features.Their clinical data and the genotype of ADH1B and ALDH2 were collected and SPSS 27.0 was used to statistically analyze the above data.Results A total of 83 subjects were included in the study,23 had multiple LVLs,most of them were seen in males,alcohol drinkers,and smokers with smoking index≥1000,and multivariate analysis showed that alcohol consumption was an independent risk factor for it(OR=6.215,P=0.008).The gene polymorphism of ADH1B and ALDH2 and their interactions did not have any significant correlation with multiple LVLs.However,among alcohol drinkers,there was a 12-fold increased risk of multiple LVLs in patients carrying the ALDH2 A allele and drinking≥50 g per day compared to those carrying the ALDH2 GG genotype and drinking<50 g per day(P=0.045).Conclusion Alcohol consumption is an independent risk factor of multiple LVLs of the esophageal mucosa in patients with early esophageal cancer,and heavy alcohol consumption in carriers of the ALDH2 A allele will significantly increase the risk of multiple LVLs,and such patients should be closely followed up with endoscopy.
