Sancai Fengsui Decoction for RTOM: A Multicenter RCT

3 de julho de 2026 atualizado por: Nanfang Hospital, Southern Medical University

A Multicenter Randomized Controlled Trial to Evaluate the Rehabilitative Efficacy of Sancai Fengsui Decoction on Radiation-Induced Oral Mucositis.

How to promote the prognosis and outcome of RTOM, restore oral function, and improve quality of life are key issues for improving the long-term outcomes of head and neck malignant tumor radiotherapy, and are also integral parts of the patient-centered Traditional Chinese Medicine "prevention-treatment-rehabilitation" system for RTOM. This project aims to thoroughly evaluate the efficacy and safety of Chinese herbal compounds in the rehabilitation phase of RTOM, targeting the long-term rehabilitation outcomes of RTOM, and to conduct a phase II clinical trial. In this project, Sancai Fengsui Decoction will be used as an oral medication to improve the rehabilitation status of RTOM, and will be compared with a placebo group. The efficacy of the oral medication will be evaluated by comparing outcome measures including the 2-week pain relief rate in the oral cavity/oropharynx, the RTOG grade remission rate for RTOM, and the relief rate of xerostomia. As an important extension of TCM prevention and treatment for RTOM, this project can provide a high-level evidence-based TCM protocol for the long-term rehabilitation of RTOM.

Medidas de resultados primários

Medida de resultado
Descrição da medida
Prazo
Pain relief rate in the oral cavity/oropharynx
Prazo: Proportion of patients with significant improvement in pain level from baseline at 2 weeks after enrollment, assessed using the Numeric Rating Scale (NRS).
The proportion of patients achieving a clinically significant improvement in pain intensity from baseline to 2 weeks post-enrollment, as assessed by the Numeric Rating Scale (NRS). Complete response (CR) was defined as a pain score of 0 (no pain), and partial response (PR) was defined as either a reduction of at least 2 points from baseline on the NRS or an improvement by one pain category, according to the following NRS classification: no pain (0), mild pain (1-3), moderate pain (4-6), and severe pain (7-10).
Proportion of patients with significant improvement in pain level from baseline at 2 weeks after enrollment, assessed using the Numeric Rating Scale (NRS).

Prazo
RTOG score remission rate of RTOM
Prazo: Evaluated at 2 weeks post-radiotherapy
The proportion of patients with a reduction of at least 1 grade in mucosal reaction at 2 weeks after radiotherapy, according to the RTOG acute radiation morbidity grading criteria (complete response defined as return to grade 0, partial response as reduction by at least 1 grade).
