The Efficacy and Safety of Traditional Chinese Medicine Qufenghuoxue Formula on Treating Peripheral Neuropathy Induced by Paclitaxel in Advanced Lung Cancer: A Randomized Clinical Trial
摘要
To assess the benefits of the traditional Chinese medicine (TCM) Qufenghuoxue formula, on the treatment of chemotherapy-induced peripheral neuropathy (CIPN) in patients with lung cancer receiving paclitaxel (PTX).
MethodsPatients with CIPN grading 2–3 were randomly assigned to three groups of TCM, vitamin B1, or warm water. The intervention duration consisted of four cycles, 3 weeks each, coinciding with the follow-up period. Primary efficacy endpoint was the proportion of patients achieving CIPN relief, defined by reduction in CIPN severity grade, while secondary endpoint evaluated completion of the recommended PTX dosing.
ResultsTCM significantly reduced grade 2–3 CIPN incidence and increased symptom relief (48.6% vs 12.0% vs 7.5%; P < 0.001) with a shorter median time to recovery compared with vitamin B1 and warm water, respectively. Additionally, it improved scores of the Functional Assessment of Cancer Therapy/Gynecologic Oncology Group–Neurotoxicity subscale (11.5 vs 20.4 vs 22.4), neuropathy pain scale (16.8 vs 27.7 vs 29.2) and quality of life (42.6 vs 36.0 vs 33.6; all P < 0.001) and also showed greater potential of completing the recommended dose level of PTX (83.8% vs 74.6% vs 59.7%; P = 0.0034) compared with vitamin B1 and warm water. With warm water as reference, the hazard ratio of PTX dose reductions/cessation due to CIPN was 0.34 (95% confidence interval [CI]: 0.168–0.67, P = 0.002) for TCM and 0.56 (95% CI: 0.314–1.008; P = 0.053) for vitamin B1.
ConclusionQufenghuoxue formula may be a promising strategy for the treatment of CIPN in patients receiving PTX.
