Background: The U.S. foreign-born population is rapidly increasing, and cancer incidence/mortality rates have been shown to differ by nativity status. Our study aimed to characterize differences in gastric cancer presentation and survival among Hispanic patients in Texas by nativity status. Methods: We conducted a retrospective review of the Texas Cancer Registry to identify Hispanic patients diagnosed with gastric adenocarcinoma between 2004 and 2017. Existing indices applied to 2010 census tract-level data were utilized to measure neighborhood socioeconomic status (nSES) and Hispanic enclaves. Nativity status was imputed for patients with missing data. Multivariable Cox proportional hazard models were fit for overall survival adjusted for age, insurance status, diagnosis year, tumor location, stage, grade, reporting source, nativity status, nSES, and Hispanic enclave. Results: Our study cohort consisted of 6186 patients and 39% were foreign-born. A greater proportion of foreign-born patients were diagnosed at < 45 years old (16% vs. 11%, p < 0.0001) and had metastatic disease at presentation (47% vs. 34%, p < 0.0001). Foreign-born patients were more often uninsured, in the lowest nSES quintile, and the highest (most ethnically distinct) quintile for Hispanic enclave. Stage-specific overall survival was significantly higher among foreign-born patients. In our multivariate model, foreign-born Hispanic patients had improved survival versus US-born (hazard ratio [HR] 0.90, 95% confidence interval [CI] 0.82-0.99). Conclusions: The clinical presentation of gastric cancer differs significantly between foreign-born and U.S.-born Hispanic patients. Foreign-born Hispanic patients have improved survival after adjusting for socioeconomic, neighborhood, and clinical factors. Further studies are needed to identify specific causal mechanisms driving the observed survival difference by nativity status.
