About

Chemotherapy-induced peripheral neuropathy (CIPN) is a common and dose-limiting toxicity of taxane-based agents, with an incidence of 57%-83%. Patients frequently develop fingertip numbness, reduced tactile sensation, and other neuropathic symptoms, which significantly impair quality of life. The severity of CIPN is strongly associated with cumulative drug dosage. Current management strategies remain inadequate, and no high-level clinical recommendations are available.

Traditional Chinese medicine (TCM) hand and foot baths have been widely applied in clinical practice due to their convenience, low cost, and high patient acceptance. The formula "Yi-Qi Yang-Xue Tong-Luo Fang," developed by the TCM Department of our hospital. Preliminary clinical use has shown reliable efficacy and good tolerability, suggesting potential benefit for CIPN.

This randomized, controlled clinical trial aims to evaluate the efficacy and safety of the TCM hand and foot bath compared with methylcobalamin (a commonly used neurotrophic agent) for paclitaxel-induced CIPN. Peripheral neurotoxicity will be assessed using standardized measures, including the Common Terminology Criteria for Adverse Events (CTCAE), the Total Neuropathy Score-clinical version (TNSc), and the M. D. Anderson Symptom Inventory with TCM module (MDASI-TCM). Changes in scores between groups will be compared to determine relative effectiveness.

Quality of life will be evaluated using validated international scales, specifically the EORTC Quality of Life Questionnaire for Breast Cancer Patients (EORTC QLQ-BR23) and the core questionnaire (EORTC QLQ-C30). These tools will provide multidimensional evaluation of treatment impact on daily functioning and well-being.

The study is expected to generate evidence on both efficacy and safety of this TCM formula, clarify its potential role in preventing or reducing CIPN progression, and assess its influence on patients' quality of life. The findings will provide clinical data to support TCM-based interventions as complementary strategies for managing chemotherapy-induced neurotoxicity.
