ABSTRACT
BACKGROUND:
Social determinants of health thoroughly explored in the literature include insurance status, race, and ethnicity. There are over 50 million self-identifying Hispanics in the United States. This, however, represents a heterogeneous population. We used a national registry to investigate for significant differences in outcomes of Hispanic patients with non-small cell lung cancer (NSCLC) in the Unites states, by geographic region of origin. MATERIALS ANDMETHODS:
We identified a cohort of Hispanic patients in the Unites states with NSCLC for which region of origin was documented within the 2004 to 2016 National Cancer Database (NCDB) registry. This included patients from Cuba, Puerto Rico, Mexico, South and Central America, and the Dominican Republic. We performed multivariate logistic regression modeling to determine whether origin was a significant predictor of cancer staging at diagnosis, adjusting for age, sex, histology, grade, insurance status, and facility type. Race was not included due to a nonsignificant association with stage at diagnosis at the bivariate level in this cohort. Subsequently, we used Kaplan-Meier modeling to identify whether overall survival (OS) of Hispanic patients differed by origin.RESULTS:
A total of 12,557 Hispanic patients with NSCLC were included in this analysis. The breakdown by origin was as follows n = 2071 (16.5%) Cuban, n = 2360 (18.8%) Puerto Rican, n = 4950 (39.4%) Mexican, n = 2329 (18.5%) from South or Central America, and n = 847 (6.7%) from the Dominican Republic. After controlling for age, sex, histology, grade, insurance status and treating facility type, we found that geographic origin was a significant predictor of advanced stage at diagnosis (P = .015). Compared to Cubans, patients of Puerto Rican origin were less likely to present with advanced disease (68.4% vs. 71.9%; OR 0.82; 95%CI 0.69-0.98; P = .026). We also identified a significant (log-rank P-value<.001) difference in OS by geographic origin, even at early-stages of diagnosis. Dominican patients with NSCLC exhibited the highest 5-year OS rate (63.3%), followed by patients from South/Central America (59.7%), Puerto Rico (52.3%), Mexico (45.9%), and Cuba (43.8%).CONCLUSION:
This study showed that for Hispanic individuals living in the Unites states, region/country of origin is significantly associated with outcomes, even after accounting for other known determinants of health. We suggest that region of origin should be studied further as a potential determinant of outcomes in patients with cancer.Palabras clave
