Effects of music therapy on anxiety in patients with cancer: study protocol of a randomised controlled trial.

introductionAlthough music therapy (MT) has been found to reduce anxiety in patients with cancer and delay tumour progression to some extent, its mechanism of action has not been determined. MT may reduce anxiety by reducing the concentrations of proinflammatory cytokines. The present study was designed to evaluate the effects of MT on anxiety and cytokine levels in patients with cancer. METHODS AND ANALYSIS: This randomised, open, single-centre parallel-controlled trial will randomise 60 patients with malignant tumours who meet the inclusion criteria in a 1:1 ratio to either an MT group or a non-MT (NMT) group. Patients in the MT group will receive emotional nursing care and individualised receptive MT for 1 week, whereas patients in the NMT group will receive emotional nursing care alone. Primary outcomes will include scores on the State-Trait Anxiety Inventory, Distress Thermometer and Hamilton Anxiety Scale. Secondary outcomes will include scores on the Quality of Life Questionnaire C30, serum concentrations of the cytokines interleukin (IL)-1β, tumour necrosis factor-α, IL-2R, IL-4, IL-6, IL-8 and IL-10, serum concentrations of the neurotransmitters 5-hydroxytryptamine, dopamine, norepinephrine, adrenocorticotropic hormone and γ-aminobutyric acid, and determination of gut microbiota populations. ETHICS AND DISSEMINATION: On 5 August 2020, the study protocol was approved by the Research Ethics Committee of the Yueyang Hospital of Integrated Traditional Chinese and Western Medicine of the Shanghai University of Traditional Chinese Medicine. The findings of this study will be published in peer-reviewed publications and presented at appropriate conferences. TRIAL REGISTRATION NUMBER: CTR2000035244.
