Abstract

Lung cancer is a disease with a high mortality rate for the U.S. Black population. There had been considerable research done on different population demographics, necessary to achieve the Healthy People 2020 overarching goals to eliminate health disparities, gain health equity and maintain quality health. Yet, the African-born Black (AFBB) population has been understudied for nonsmall cell lung cancer (NSCLC). This study sought to determine whether within race differences in stage at diagnosis and treatment of NSCLC exists between AFBB and American-born Blacks (AMBB) populations in the United States. The study data is secondary data collected as part of the National Cancer Institute's Surveillance Epidemiologic and End Result (SEER) Program from 2004-2011. Athough no significant difference was found between AFBB (n = 119) and AMBB (n = 238) relative to NSCLC stage at diagnosis, differences in treatments were found. The proportion of AFBB patients with early stage (I and II) NSCLC who underwent surgery differed significantly from that of AMBB (p < 0.05); AFBB patients were more likely to receive surgical therapy. The proportion of AFBB patients with stages I-IV of the disease who received radiation treatment also differed significantly from that of AMBB patients (p < 0.05); the latter were more likely to receive radiation therapy. Results from logistic regression analysis indicate that AFBB patients were more likely to receive surgical treatment while AMBB patients were more likely to receive radiation treatment. This study outcome can inform other NSCLC research to provide better insights to the cause of the treatment differences within the race from differing birth places, and efficient planning, evaluation of control programs and management of the disease.
