      Background:
      Disparities exist in cancer outcomes. NSCLC outcomes have improved in recent years but effects of socioeconomic factors have not been reported.

      Method:
      The National Cancer Database with NSCLC incident cases between 2004-2013 was analyzed. Overall survival (OS) was explored by several available factors with a focus on race and socioeconomic factors.

      Result:
      A total of 1,150,722 NSCLC patients were included with majority White (86.4%) followed by Black (10.6%) and a smaller proportion of Asians and Hispanics. Patients were evenly distributed among income quartiles and majority were insured (96.7%), lived in a metro area (81.7%) and treated at non-academic facilities (68.5%). Overall median OS was 13.1 months and significantly better for Asians (18.2 months) and Hispanics (16.6 months) as compared to Whites (13.2 months) and Blacks (11.5 months). (Figure 1, p<0.001) Outcomes were worse with higher comorbidity score, TNM stage and treatment at community or high-volume facility. Socioeconomic factors other than race associated with worse outcome included lower education and median income, uninsured status and Central geographic region. (Table 1) Figure 1 Figure 2





      Conclusion:
      In this largest analysis thus far, patient race and socioeconomic factors were found to significantly influence NSCLC survival. These must be addressed for equitable healthcare benefit and outcomes.

      OA 06.07 - Survival Trends Among Non-Small Cell Lung Cancer (NSCLC) Patients Over A Decade: Impact of Initial Therapy at Academic Centers (ID 10149)

      Background:
      Treatment of NSCLC is rapidly advancing and academic centers are considered equipped with better expertise. NSCLC outcome trends in novel therapeutic era and impact of initial treatment at academic centers have not been reported.

      Method:
      The National Cancer Database (NCDB) with NSCLC incident cases between 2004-2013 was used. Overall survival (OS) was plotted by year of diagnosis and type of treatment facility, accounting for several available factors in NCDB.

      Result:
      A total of 1,150,722 NSCLC patients were included and separated by initial treatment facility type (academic: 31.5%, non-academic: 68.5%). Several characteristics were significantly different between the two cohorts (Table 1). Median OS for all patients was 13.1 months and improved significantly for those diagnosed in 2010-2013 (14.8 months) as compared to 2004-2009 (12.4 months) (p<0.001). Treatment at academic centers was associated with reduced risk of death [Multivariate HR=0.91 (95% CI 0.906-0.919), P<0.001]. Four-year OS for academic and non-academic cohorts was 25% and 19%, respectively (p<0.001), the difference more pronounced in stage 1-3. (Figure 1) Figure 1 Figure 2





      Conclusion:
      In this largest analysis thus far, NSCLC survival has improved over time and type of treatment facility significantly influences survival. Factors influencing treatment facility choice should be addressed for easier access to academic centers.
