e21117 Background: Non-small cell lung cancer (NSCLC) is the most prevalent form of lung cancer. Many studies have evaluated the association of social determinants with outcomes in early-stage NSCLC. These studies have shown statistically and clinically significant associations between overall survival (OS) and other social factors (e.g marital status, educational attainment). The aim of our study was to better understand the role of various social determinants of health (SDH) on OS in advanced-stage NSCLC patients in a community oncology practice in Florida. Methods: In this retrospective study, 125 patients with stage III and IV NSCLC were recruited between January 1st, 2014 until December 31st, 2018. We performed both categorical and continuous analyses (Pearson’s chi-square and Kruskal-Wallis test, respectively) to evaluate the association between median OS and several independent variables, including; gender, race, marital status, insurance status, living status, receiving financial assistance (FA), alcohol use, and smoking histories. OS is defined as the date of diagnosis up to the date of death. Other confounders that were analyzed included histology, treatment modality, comorbidities, and performance status of the patients. Results: Of the total study population (n = 125), 60% identified as male with a mean age of 73 years for the study population. The majority of patients (89%) identified as white; 56% were married, and 81% lived with someone. 66% of patients had an HMO insurance plan, and 51% of patients obtained FA to help with treatment care costs. 47% of patients identified as former smokers and 54% denied any alcohol use. The median OS for the patient population was 0.756 years. Chi-square analyses revealed that patients who received FA were more likely to live longer than median OS as opposed to patients that did not receive FA (OR = 2.41, 95% CI [1.18, 4.96], p = 0.050). Kruskal-Wallis analyses demonstrated that patients receiving FA had nearly a two-fold increase in median OS compared to patients without financial assistance (median OS = 1.01 years vs. 0.545 years, respectively; p = 0.013). However, other social determinants evaluated did not have a significant impact on relative OS in advanced-stage NSCLC. Conclusions: Ultimately, our study concludes that receiving FA has a significant association with increased OS in advanced-stage NSCLC patients. This study highlights the importance of reducing the financial burden of advanced-stage NSCLC patients and how FA impacts patient outcomes. Future prospective cohort studies with a larger sample size are warranted to identify other SDH, as well as the underlying mechanisms affecting median OS, in patients with advanced-stage NSCLC.
