Patient Perception of the Relevance of Quality-of-Life Questionnaires in Waldenström Macroglobulinaemia: An International Survey.

Waldenström Macroglobulinaemia is an indolent disease which is recognised as contributing to a diverse range of disabling symptoms which can impact quality of life. Little data are available in evaluating patient and healthcare professional views on quality-of-life questionnaires (QLQ) used to evaluate quality of life in Waldenström Macroglobulinaemia. We aimed to assess patient perception of their disease and the relevance of the currently employed QLQs in practice by patients and healthcare professionals. One-hundred-and-twenty patients (22% treatment-naïve) and thirty-four healthcare professionals completed an international survey to understand their perception of the relevance of the currently employed QLQ. Out of 415 questions, 257 questions were classified by patients as relevant. Five themes were discerned as relevant: fatigue, mobility, dyspnoea, paraesthesia, pain in the hands and feet, sleep (physical health limitations); contentment (psychological impact); social and family support. The following were considered irrelevant: lumps or swelling, dry mouth, trouble hearing, sexual dysfunction (physical symptoms); post-traumatic stress (psychological impact); education and training and financial support. Healthcare professionals identified EORTC QLQ-C30 as the most commonly used instruments for Waldenström Macroglobulinaemia trials.
