Abstract
Purpose
Novel multiple myeloma (MM) therapies have increased patient longevity but are often associated with notable symptom burden. This study quantified the effect of general symptom level, specific symptoms, and treatment-related adverse events (AEs) on MM patients’ health-related quality of life (HRQoL).
Methods
The European Organization for Research and Treatment of Cancer (EORTC) generic cancer questionnaire (Quality of Life Questionnaire Core 30) and MM-specific questionnaire (QLQ-MY20) were used in this study to assess patients’ HRQoL. Data were collected on sociodemographics, disease and treatment history, and the presence/severity of MM-related symptoms or treatment-related AEs from patients with MM in 11 UK and German centers. Multiple regression analyses were conducted.
Results
Of 154 patients (63 % male; mean age, 66.4 years; mean time since diagnosis, 3.7 years; 52 % currently on treatment; and 43 % with ≥1 prior MM therapy), 25, 32, 31, and 11 % were severely symptomatic, moderately symptomatic, mildly symptomatic, and asymptomatic, respectively. Fatigue (59 %), bone pain (51 %), sleepiness (36 %), hypoesthesia or paresthesia (33 %), and muscle cramps (31 %) were most commonly reported. Moderate and severe general symptom levels, bone symptoms, depression, and mental status changes were identified as strong determinants of HRQoL.
Conclusions
Severity, type of disease symptoms, and treatment-related AEs are important HRQoL determinants in patients with MM, allowing for targeted treatment.
