The Dynamics of Financial Toxicity in Multiple Myeloma.

INTRODUCTION/BACKGROUND: People with multiple myeloma are at risk for financial toxicity due to the high cost of treatment and prolonged treatment duration. However, little data exist regarding financial toxicity among people with myeloma.

PATIENTS AND METHODS

In this study, a cohort of 135 patients were recruited from an ongoing observational trial to complete the Comprehensive Score for financial Toxicity (COST). Participants were sent follow-up surveys at 3, 6, and 12 months.

RESULTS

The median age was 68 years; the majority were non-Hispanic whites (88%), male (63%), held a college degree (61%), and had left the workforce (70%). The median time from myeloma diagnosis was 28 months. The median COST score was 27; 48% of participants had a score below 27 and considered to have financial toxicity. The only characteristic associated with financial toxicity was a college degree. After controlling for other covariates, those with a college education were 69% less likely to have financial toxicity. Of the 108 participants who completed a follow-up survey, 34% reported changes in their financial toxicity status at a subsequent time point. Transitioning from not having financial toxicity to having financial toxicity was more common than the reverse.

CONCLUSION

Because financial toxicity is a dynamic process, which patients are experiencing it at any given time is difficult to predict. Focusing the research agenda on improved detection and intervention may be warranted.
