PURPOSE: Little qualitative research exploring the impact of multiple myeloma (MM) and its treatment on the health-related quality of life (HRQL) of patients has been published. This study aimed to explore the burden of MM symptoms and treatment and the impact of these on HRQL. A model was developed to illustrate key concepts and their interrelationships.

METHODS: Patients with MM were recruited to this cross-sectional, qualitative study through a patient panel and at two clinical sites in the USA. An interview discussion guide was developed using a review of published literature and interviews with experienced MM clinicians. In-depth, semistructured telephone interviews with MM patients were conducted to explore their experiences of the disease and its treatment. Data were analyzed using a thematic analysis approach.

RESULTS: Twenty MM patients at various stages of treatment participated in open-ended, semistructured interviews. Patients reported both current and previous MM symptoms; most had experienced fatigue and pain. Other commonly reported symptoms were fractures, anemia, neuropathy, aches, and infections. MM treatment was found to have a negative impact on patients’ HRQL; treatment-related adverse events included fatigue, neuropathy, insomnia, and gastrointestinal symptoms. MM treatment placed a substantial psychological and physical burden on patients, disrupting social activities, decreasing independence, and impacting on relationships. A model was developed to illustrate the relationship between these concepts.

CONCLUSION: The conceptual model developed in this study illustrates the many aspects of MM and its treatment and how they can have a negative impact on patients’ HRQL.
