Abstract
BACKGROUND: Buyang Huanwu Decoction (BYHWD) is a traditional Chinese prescription, originally derived from Yi Lin Gai Cuo during the Qing Dynasty. This study aimed to evaluate the efficacy and safety of BYHWD in the prevention of taxane-induced peripheral neuropathy (TIPN) in patients with breast cancer. METHODS: This single-center, statistician-blinded, parallel-group, simple randomized, no-treatment controlled study was conducted at the China-Japan Friendship Hospital in Beijing. Sixty breast cancer patients scheduled to receive nab-paclitaxel-based chemotherapy were randomly assigned to either the BYHWD group (N = 30) or the control group (N = 30) using simple randomization procedures. The data analysts were unaware of the treatment allocation. The primary efficacy endpoints were the incidence and severity of TIPN in the 2 groups, assessed using the Common Terminology Criteria for Adverse Events (CTCAE) and Patients' Neurotoxicity Questionnaire (PNQ). The secondary efficacy endpoint was the score of Functional Assessment of Cancer Therapy-Breast for both groups. The primary safety endpoints were routine blood test results and liver and renal functions. Both groups were subjected to 4 chemotherapy cycles. Efficacy and safety analyses were conducted on an intention-to-treat basis. RESULTS: The incidence of TIPN in the BYHWD group was 50.0%, which was lower than the 80.0% incidence in the control group (β = -1.881 [95%CI -3.274, -.488]; P = .008, adjusted). The probability of TIPN in the BYHWD group was 15.2% of that in the control group, representing a significant reduction in incidence (odds ratio = .152, [95%CI .038, 0.614]; P = .008, adjusted). The CTCAE and PNQ grades of the BYHWD group were 1.527 and 1.495 points lower than those of the control group at the same cycle, respectively (CTCAE: β = -1.527 [95%CI -2.522, -.533]; P = .003, adjusted; PNQ: β = -1.495 [95%CI -2.501, -.489]; P = .004, adjusted, respectively). After treatment, the Functional Assessment of Cancer Therapy-Breast scores in the BYHWD group were significantly better than those in the control group (P = .003), especially in the physiological, functional, and additional concerns domains. CONCLUSION: Buyang Huanwu decoction (BYHWD) can effectively prevent TIPN and improve the quality of life in patients with breast cancer.
