Goal: To study the feasibility of using repeat esophagogastroduodenoscopy (EGD) to screen for Helicobacter pylori infection and gastric cancer in an Asian immigrant cohort.
Background: Immigrants in the United States (US) from countries with high per capita rates of gastric cancer remain at higher risk for gastric cancer. The existence of the possibly modifiable risk factor of H. pylori infection and the poor outcomes associated with late-stage disease make screening higher-risk groups with EGD an appealing possibility. It is unknown whether Asian immigrants in the US would accept an EGD-based strategy for gastric cancer screening.
Study: Cross-sectional study of adult Chinese immigrants in New York City with dyspepsia who underwent EGD in an earlier gastric cancer detection study, who were offered a second EGD four years later. Our main outcome measure was acceptance or refusal of repeat EGD.
Results: Seventy-three of the 115 Chinese participants in the earlier study were successfully contacted for this current study. Twenty-three of 73 (32%) underwent repeat EGD. Leading reasons given for declining were lack of symptoms and lack of time. Significantly associated with acceptance of repeat EGD was the belief that EGD will find stomach cancer "nearly always" in someone who has it (P=0.0054; odds ratio=14.0, 2.1 to 94.2 95% confidence interval).
Conclusions: Acceptance of repeat EGD for gastric cancer detection in a cohort of Chinese immigrants was relatively low despite the mitigation of cost and language factors, 2 major barriers to healthcare access. Relocation seemed to be a factor as well. In this population, perceptions of the benefits of EGD may influence acceptance of testing for cancer detection purposes.
