Non‐small cell lung cancer disparities in stage at presentation and treatment for Asian American, Native Hawaiian, and Pacific Islander women

Abstract

AbstractBackground and ObjectivesAsian Americans, Native Hawaiians, and Pacific Islanders (AANHPI) represent the fastest‐growing group in the United States. While described in aggregate, great variations exist within the community. We aimed to determine whether there were differences in stage at presentation and treatment status among AANHPI women with non‐small cell lung cancer (NSCLC).MethodsBetween 2004 and 2016, we identified 522 361 female patients with newly diagnosed NSCLC from the National Cancer Database. Multivariable logistic regression models were used to define adjusted odds ratios (aORs) of presenting with stage IV disease and not receiving treatment.ResultsAANHPI women were more likely to present with stage IV disease compared to White (54.32% vs. 40.28%, p < 0.001). Aside from Hawaiian, Pakistani, and Hmong women, all other ethnic groups had greater odds of presenting with stage IV disease than White women. AANHPI women <65 years were more likely to present with stage IV disease (p = 0.030). Only Vietnamese women showed a significant difference (aOR = 1.30 [1.06–1.58], p = 0.010) for likelihood of receiving treatment compared to White.ConclusionsDifferences in stage at presentation and treatment status in women with NSCLC were observed among AANHPI ethnic groups when populations were disaggregated.
