- Abstract
Objective: The purpose of this study was to evaluate overall survival (OS) outcomes by race, stratified by country of origin in patients diagnosed with NSCLC in California. Methods: We performed a retrospective analysis of nonsmall cell lung cancer (NSCLC) patients diagnosed between 2000 and 2012. Race/ethnicity was defined as White (W), Black (B), Hispanic (H), and Asian (A) and stratified by country of origin (US vs. non‐US [NUS]) creating the following patient cohorts: W‐US, W‐NUS, B‐US, B‐NUS, H‐US, H‐NUS, A‐US, and A‐NUS. Three multivariate models were created: model 1 adjusted for age, gender, stage, year of diagnosis and histology; model 2 included model 1 plus treatment modalities; and model 3 included model 2 with the addition of socioeconomic status, marital status, and insurance. Results: A total of 68,232 patients were included. Median OS from highest to lowest were: A‐NUS (15 months), W‐NUS (14 months), A‐US (13 months), B‐NUS (13 months), H‐US (11 months), W‐US (11 months), H‐NUS (10 months), and B‐US (10 months) (p < 0.001). In model 1, B‐US had worse OS, whereas A‐US, W‐NUS, B‐NUS, H‐NUS, and A‐NUS had better OS when compared to W‐US. In model 2 after adjusting for receipt of treatment, there was no difference in OS for B‐US when compared to W‐US. After adjusting for all variables (model 3), all race/ethnicity profiles had better OS when compared to W‐US; B‐NUS patients had similar OS to W‐US. Conclusion: Foreign‐born patients with NSCLC have decreased risk of mortality when compared to native‐born patients in California after accounting for treatments received and socioeconomic differences. Foreign‐born patients with NSCLC have decreased risk of mortality when compared to native born patients in California after accounting for treatments received and socioeconomic differences.
