e20530 Background: Multiple myeloma (MM) accounts for nearly 17% of all hematological malignancies and 2% of all cancer-related deaths in 2018. Despite new treatment options, survival disparities among African Americans (AA) and other ethnic minorities still exist. Although cytogenetics and advanced age are high-risk features, equal healthcare access may also impact outcomes. We aim to investigate the social and biological factors which affect overall survival in patients with MM in a community setting with a predominantly AA population. Methods: We retrospectively identified MM cases diagnosed from January 1, 2013 and March 30, 2019, from our tumor registry. We collected demographic, clinical, histopathologic and treatment variables. Our primary endpoint was overall survival (OS). Overall and median survival with 95% confidence intervals were obtained using Kaplan Meier estimates. Results: We identified 73 patients with MM. Median age was 70 years (range, 42-88 years), 31 were female (42%) and 58 were AA (79%). Median household income in the AA group was $37,832 and $50,810 in the non-AA group ( p< 0.05). AA had a median overall survival (OS) of 15.9 months (95% CI, 8.2-23.7) compared to non-AA, 21.9 months (95% CI, 2.1-41.7). After a median follow-up of 20 months, the HR for death in AA was 1.32 (95% CI, 0.71-2.5); p= 0.37. None of the variables investigated were independently associated with an increased risk of mortality. Conclusions: Social determinants of health play a major role in community-based cancer centers, including access to care, income and social support. A difference in household income was found between both groups but was not independently associated with a survival advantage. Although, our results show AA patients with MM have a shorter OS compared to non-AA, this failed to reach statistical significance. The size of our sample limited the discovery of potential discrepancies in social determinants of health between both groups and their effect on outcomes. Larger-scale community-based studies are indispensable to investigate these differences further. [Table: see text]
