Efficacy and safety of acupuncture for chemotherapy-induced leukopenia: A systematic review and meta-analysis

Leukopenia is one of most common types of myelosuppression secondary to chemotherapy. The main methods used to treat leukopenia after chemotherapy have various limitations. Several studies have reported the role of acupuncture in the prevention and treatment of leukopenia, but the quality of the study is uneven. Here, we used a systematic review and meta-analysis to evaluate the efficacy and safety of acupuncture in the treatment of leukopenia after chemotherapy. METHODS: We searched the databases of the Cochrane Central Register of Controlled Trials (CENTRAL), the Cochrane Library, Medline (via PubMed), EMBASE (via embase.com), the China National Knowledge Infrastructure Database (CNKI), the Chinese Biomedical Literature Database (CBM), the Chinese Scientific Journal Database (VIP database) and the Wanfang database to collect randomized clinical trials (RCTs) on acupuncture in the treatment of leukopenia after chemotherapy. Cochrane systematic reviewer manual 5.2 was used for bias risk assessment. RevMan5.3 statistical software was applied for statistical analysis. RESULTS: Fifteen RCTs were included in this study, with a total of 1130 patients. Meta-analysis results showed that acupuncture can increase white blood cell (WBC) count after chemotherapy [MD = 1.18, 95% CI (0.80, 1.57), P < .00001], reduce the incidence of myelosuppression [RR = 0.38, 95% CI (0.23, 0.63), P = .0002], and improve the clinical treatment effectiveness [RR = 1.20, 95% CI (1.00, 1.43), P = .05]. The differences were statistically significant. CONCLUSION: It is recommended to use acupuncture in the treatment of leukocytopenia after chemotherapy, but this result needs further research for verification.
