Chemotherapy-Induced Peripheral Neuropathy and its Impact on Health-Related Quality of Life among Multiple Myeloma Patients: A Single-Center Experience.

aimChemotherapy-induced peripheral neuropathy (CIPN) is a long-term neurological health issue in patients diagnosed with multiple myeloma (MM). The aim of this study was to assess CIPN symptoms and health-related quality of life (HRQOL) among MM patients.

methodsA cross-sectional survey was conducted among patients diagnosed with MM in a tertiary care hospital using a self-reported Arabic questionnaire, European Organization for Research and Treatment of Cancer Quality-of-Life Questionnaire for CIPN scale (QLQ-CIPN20). The HRQOL was assessed using EORTC multiple myeloma module (QLQ-MY20). Categorical variables were reported in frequency tables and percentages. Age and duration of MM diagnosis were reported as mean and standard deviation. Survey responses were presented using descriptive statistics.

resultsIn total, 62 patients had participated. Males were 60%. The average age was 58.74 ± 11.49 years. On sensory scale, 20% reported "quite a bit"/"very much" tingling in fingers/hands, 23% in toes/feet, 39% numbness in fingers/hands, 37% in toes/feet, and 43% reported trouble standing or walking. On motor scale, 40% reported trouble walking and 60% had difficulty in climbing stairs/standing up from chair. On autonomic scale, 27% reported orthostatic hypotension and only 13/37 (46%) males reported erectile dysfunction. For HRQOL, 50% reported bone aches/pain, 42% reported back pain, 57% reported feeling ill, 33% reported lost hair, 35% had been thinking about their illness, whereas 28% were worried about future health and 22% had reported being worried about dying.

conclusionMM patients encounter CIPN symptoms with impaired HRQOL. Capturing CIPN as a patient-reported outcome needs to be considered in routine clinical practice.
