While NSCLC patient outcomes have improved over time, the influence of race and socioeconomic factors on these outcomes has historically not been well studied. By using data from the National Cancer Database on NSCLC incident cases from 2004-2013 in the U.S., Dr. Lou and her team sought to determine whether a correlation exists between patients' overall survival (OS) and various socioeconomic factors and race.
Of the more than 1.1 million cases studied, 86.4 percent were White, 10.6 percent were Black, and smaller proportions were Asian and Hispanic. Income was fairly evenly distributed. Additionally, a majority of the cases were individuals who were insured, lived in a metro area and received care at non-academic facilities.
