About

1. To evaluate the preventive and therapeutic effects of Qibei Jiedu Formula on acute radiation dermatitis in breast cancer patients, including the incidence of grade 2 or higher radiation dermatitis, wound healing time, and symptom relief.
2. To observe the safety profile of Qibei Jiedu Formula.
3. To investigate the potential role of Qibei Jiedu Formula in improving patients' quality of life.
4. To explore the potential mechanism of action of Qibei Jiedu Formula in preventing and treating acute radiation dermatitis in breast cancer patients through exploratory indicators such as inflammatory cytokines and skin microbiota.
5. This study is a small-scale exploratory clinical trial. It aims to collect preliminary efficacy and safety data from 60 participants to assess the "add-on effect" of Qibei Jiedu Formula on top of "standard basic care". The results are intended for estimating effect sizes and generating hypotheses to inform future large-scale studies, not for drawing definitive conclusions.

Full description

Acute Radiation Dermatitis (ARD) following breast cancer radiotherapy has an incidence rate as high as 95%, with grade 3 or higher dermatitis leading to unplanned radiotherapy interruption in 15-20% of patients. This not only compromises treatment efficacy but also significantly impairs patients' quality of life. Current conventional Western medical management primarily relies on corticosteroids and moisturizers, yet faces limitations in efficacy and notable side effects. Developed based on the Fuzheng Quyu Jiedu (Strengthening Vital Qi, Removing Stasis, and Detoxifying) theory, the Qibei Jiedu Formula has shown promising anti-inflammatory, antipruritic, and wound-healing effects in preliminary clinical observations.

Led by Professor Feng Li's team from the Cancer Hospital of the Chinese Academy of Medical Sciences, this project adopts a multicenter, randomized, double-blind, placebo-controlled clinical trial design. It plans to enroll 60 breast cancer patients scheduled for radiotherapy to systematically evaluate the clinical efficacy and safety of Qibei Jiedu Formula in preventing and treating ARD. The study aims to provide high-level evidence-based medical data for the integrated Chinese and Western medicine prevention and management of ARD. Furthermore, it seeks to establish a safer and more effective treatment regimen, thereby reducing unplanned radiotherapy interruptions and improving oncologic outcomes. The findings are expected to offer an evidence-based rationale for the TCM-based prevention and treatment of radiation dermatitis, provide a new option for clinical practice, and contribute positively to enhancing the quality of life of cancer patients, holding significant social value.
