INTRODUCTION: Outcomes in multiple myeloma (MM) have improved significantly over time. This is true overall for all patients as well as patient subgroups based on age and race/ethnicity. Despite this, disparities are noted in outcomes when looking at racial subgroups. MATERIALS AND METHODS: We performed an analysis from the population-based Surveillance, Epidemiology, and End Results (SEER) database to evaluate improvement in relative survival rates (RSRs) for young (≤ 40 years at the time of MM diagnosis) and older (> 40 years at the time of MM diagnosis) over time by race/ethnicity, specifically focusing on Hispanic patients with MM. Expected survival was estimated using the age- and gender-specific death rates from the United States population. RSR was provided as the ratio of the observed to expected survival at individual time points. Five-year and 10-year RSRs were calculated for patients based on treatments modalities available in various time periods. RESULTS: We identified a total of 89,451 patients with MM in SEER, of which 1460 patients formed the young patients with MM (≤ 40 years) cohort. Five- and 10-year RSR improved significantly over time for all patients and older patients (> 40 years) by race (all P < .001). Evaluating the younger patients, RSR improved significantly for non-Hispanic whites and non-Hispanic blacks, but not for Hispanics. This was true for the 5-year (P = .08) and 10-year (P = .13) RSRs. CONCLUSION: We report a lack of significant benefit in long-term outcomes for younger Hispanic patients with MM over time. This could be owing to multifactorial causes that need to be addressed to mitigate outcome disparities.
