摘　　要：The study by López-Gómez et al,reports a significantly low prevalence(4.5%)of Helicobacter pylori(H.pylori)infection in esophageal cancer patients,contrasting sharply with the general population's infection rate.This finding challenges the established negative association between H.pylori and gastric malignancies,suggesting a potential protective role of H.pylori against esophageal carcinoma,particularly in the context of widespread proton pump inhibitor use.However,the study’s retrospective nature,single-center design,and small sample size limit the generalizability of the findings and raise concerns about selection bias and statistical power.Diagnostic methods primarily based on histology may not detect all cases,especially those with prior antibiotic or proton pump inhibitor use.Additionally,the study does not account for various confounding factors such as dietary habits,socio-economic status,and genetic predispositions that could affect the association between H.pylori and esophageal carcinoma.Further research with larger,more diverse cohorts and comprehensive data collection is necessary to clarify the complex relationship between H.pylori and esophageal carcinoma and substantiate these preliminary findings.
