Music interventions for improving psychological and physical outcomes in cancer patients

Having cancer may result in extensive emotional, physical and social suffering. Music interventions have been used to alleviate symptoms and treatment side effects in cancer patients.

To assess and compare the effects of music therapy and music medicine interventions for psychological and physical outcomes in people with cancer. SEARCH METHODS: We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (2016, Issue 1), MEDLINE, Embase, CINAHL, PsycINFO, LILACS, Science Citation Index, CancerLit, CAIRSS, Proquest Digital Dissertations, ClinicalTrials.gov, Current Controlled Trials, the RILM Abstracts of Music Literature, http://www.wfmt.info/Musictherapyworld/ and the National Research Register. We searched all databases, except for the last two, from their inception to January 2016; the other two are no longer functional, so we searched them until their termination date. We handsearched music therapy journals, reviewed reference lists and contacted experts. There was no language restriction. SELECTION CRITERIA: We included all randomized and quasi-randomized controlled trials of music interventions for improving psychological and physical outcomes in adult and pediatric patients with cancer. We excluded participants undergoing biopsy and aspiration for diagnostic purposes. DATA COLLECTION AND ANALYSIS: Two review authors independently extracted the data and assessed the risk of bias. Where possible, we presented results in meta-analyses using mean differences and standardized mean differences. We used post-test scores. In cases of significant baseline difference, we used change scores. MAIN RESULTS: We identified 22 new trials for inclusion in this update. In total, the evidence of this review rests on 52 trials with a total of 3731 participants. We included music therapy interventions offered by trained music therapists, as well as music medicine interventions, which are defined as listening to pre-recorded music, offered by medical staff. We categorized 23 trials as music therapy trials and 29 as music medicine trials.The results suggest that music interventions may have a beneficial effect on anxiety in people with cancer, with a reported average anxiety reduction of 8.54 units (95% confidence interval (CI) -12.04 to -5.05, P
