Effect of music therapy on chemotherapy-induced nausea and vomiting in gastrointestinal cancer: A systematic review and meta-analysis.

BACKGROUND

Chemotherapy is the primary treatment for patients with advanced gastrointestinal cancer, but it has many adverse reactions, particularly nausea and vomiting. Music therapy can reduce anxiety symptoms, avoid the response to the human body under various stress conditions through psychological adjustment, and improve the adverse reactions of chemotherapy.

AIM: To investigate the impact of music therapy on relieving gastrointestinal adverse reactions in chemotherapy for patients with digestive tract cancer by meta-analysis.

METHODS

EMBASE, PubMed, OVID, WoS, CNKI, CBM, and VIP database were all used for searching relevant literature, and the efficacy after treatment was combined for analysis and evaluation.

RESULTS

This study included seven articles. The results of meta-analysis indicated that music therapy could reduce the nausea symptom score of patients after chemotherapy [mean difference (MD) = -3.15, 95% confidence interval (CI): -4.62 to -1.68, Z = -4.20, P < 0.0001]. Music therapy could reduce the vomiting symptom score of patients after chemotherapy (MD = -2.28, 95%CI: -2.46 to -2.11, Z = -25.15, P < 0.0001). Furthermore, music therapy could minimize the incidence of grade I and above nausea or vomiting in patients after chemotherapy (odds ratio = 0.38, 95%CI: 0.26-0.56, Z = -4.88, P < 0.0001). Meta-regression analysis found that publication year was not a specific factor affecting the combined results. There was no significant publication bias (P > 0.05).

CONCLUSION

Music therapy can significantly improve the scores of nausea and vomiting symptoms in patients with digestive system cancer during chemotherapy and reduce the incidence of grade I and above nausea and vomiting after chemotherapy, making it an effective psychological intervention method worthy of clinical promotion.
