Resumen

Background: Latino patients have a higher incidence of gastric cancer compared to non-Latino white patients nationwide, with greater disparities in South Texas. However, the impact of Latino ethnicity on mortality in gastric cancer is controversial. We evaluated clinicopathological characteristics and survival outcomes in Latino vs. non-Latino white patients at our National Cancer Institute (NCI)-designated cancer center and its affiliated hospital. Methods: We conducted a retrospective chart review of Latino and non-Latino white patients diagnosed with gastric cancer who were seen at Mays Cancer Center at the University of Texas Health in San Antonio, Texas, from 2000-2018. Median overall survival (mOS) was estimated from Kaplan-Meier curves and groups were compared with the log-rank test. Results: A total of 193 patients met inclusion criteria and 65% (n=126) were Latino. Median age for all patients was 61 years. Female patients represented almost 50% of Latinos vs. 36% of non-Latino whites. There were no differences in Eastern Cooperative Oncology Group (ECOG) performance status, primary tumor location, stage, Helicobacter pylori status, HER2 status, or histologic subtype at diagnosis. Median overall survival was 14 months (95% CI: 13-36) for Latinos vs. 33 months (95% CI: 14 to n/a) for non- Latino whites (P=0.36). Conclusions: Compared to non-Latino white patients, Latino patients with gastric cancer at a majority-minority cancer center in South Texas did not have significant differences in baseline clinicopathologic features or survival outcomes. Further prospective studies are needed to evaluate epidemiologic, pathogenetic, and molecular differences in gastric cancer in order to identify variables associated with treatment efficacy and survival.
