The effectiveness of music therapy for patients with cancer: a systematic review and meta-analysis.

AIMS
To assess the effectiveness of music therapy on the quality of life, anxiety, depression, and pain of patients with cancer.


DESIGN
Systematic review.


DATA SOURCES
Five electronic databases were searched in September 2018 for randomized controlled trials evaluating music therapy for patients with cancer.


REVIEW METHODS
The quality of the studies was assessed using the risk of bias tool recommended by the Cochrane Handbook Version 5.1.0 and the Revman version 5.3 software was used to perform the meta-analysis. The outcomes were overall quality of life, anxiety, depression and pain.


RESULTS
A total of 19 trials evaluating 1548 patients were included in this study, of which 765 were in the control group and 783 in the experimental group. Compared with standard care, music therapy can significant increase the score of overall quality of life in patients with cancer. In addition, music therapy was found to be more effective for decreasing the score of anxiety, depression, and pain.


CONCLUSION
Music therapy can improve the overall quality of life of patients with cancer, with an observed optimal intervention duration of 1-2 months. Meanwhile, anxiety, depression, and pain are improved as well. Nevertheless, high-quality trials are still needed to further determine the effects of music intervention in supportive cancer care.
