Kind of blue - a systematic review and meta-analysis of music interventions in cancer treatment

ABSTRACT

Objectives

Music may be a valuable and low-cost coping strategy for cancer patients. We conducted a systematic review and meta-analysis to identify the psychological and physical effects of music interventions in cancer treatment.

Methods

We included randomized, controlled trials with adult patients in active cancer treatment exposed to different music interventions versus control conditions. Qualitative studies and systematic reviews were excluded. We identified a total of 2624 records through two systematic searches (June 2015, September 2016) in PubMed, Scopus, EMBASE, Cinahl, Web of Science, Cochrane and PsycINFO and used Risk of Bias Assessment, GRADE and Checklist for Reporting Music-Based Interventions to evaluate the music applied and quality of the studies. We conducted meta-analyses using Review Manager (version 5.3). PROSPERO reg. no. CRD42015026024.

Results

We included 25 RCT´s (N=1784) of which 20 were eligible for the meta-analysis (N=1565). Music reduced anxiety (SMD -0·80 [95% CI -1·35 to -0·25]), pain (SMD -0·88 [95% CI -1·45 to -0.32]), and improved mood (SMD -0·55 [95% CI -0·98 to -0·13]). However, studies were hampered by heterogeneity with I² varying between 54% and 96%. Quality of the studies ranged from very low to low. The most effective mode of music intervention appeared to be passive listening to self-selected, recorded music in a single session design.

Conclusions

Music may be a tool in reducing anxiety, pain and improving mood among cancer patients in active treatment. However, methodological limitations in the studies carried out so far prevent firm conclusions.
