A cross-sectional observational study of health-related quality of life in adults with multiple myeloma

Background The purpose of this manuscript is to describe health-related quality of life (HRQoL) outcomes in a United States (US)-based sample of multiple myeloma (MM) patients and identify characteristics associated with poor HRQoL. Patients and methods MM patients identified through the Tumor Registry of a Southeastern US medical center were mailed surveys assessing patient characteristics and HRQoL outcomes. HRQoL outcomes were measured using PROMIS short form instruments which included measures of global health (global physical health and global mental health), physical function, and ability to participate in social roles and activities (social function). HRQoL domain scores were summarized, and best subset linear regression was used to identify predictors of HRQoL. Results A total of 690 patients completed and returned surveys for a response rate of 64.7%. Respondents reported global physical health (44.9), global mental health (47.5), and physical function (44.1) significantly worse than the general population mean of 50 (p < .0001). Social function (49.5) did not differ significantly (p = .09). Worse socioeconomic status, higher comorbidities, not being in remission, and past receipt of radiation therapy were significantly associated with worse HRQoL. Treatment status and time since diagnosis were not associated with HRQoL outcomes. Conclusions Patients with MM have significantly worse HRQoL than the general population. These findings warrant increased attention from clinicians and researchers. More research is needed to better describe the relationship between treatment patterns and HRQoL in patients with MM, and to identify effective interventions.
