Sancai Fengsui Decoction for RTOM: A Multicenter RCT

July 3, 2026 updated by: 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.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Sancai Fengshui Tang group
Sancai Fengsui Decoction group: Orally administered Sancai Fengsui Decoction, 30 mL per dose, three times daily, with a treatment course of two weeks.
Drug: Sancai Fengsui Decoction
To investigate the efficacy of Sancai Fengsui Decoction in the treatment of RTOM，orally administered Sancai Fengsui Decoction, 30 mL per dose, three times daily, with a treatment course of two weeks.
Placebo Comparator: Placebo control group
Placebo group: The control group received a placebo that matched the color, odor, and taste of the Sancai Fengsui Decoction but contained no active ingredients of the decoction. The usage and dosage were the same as those in the Sancai Fengsui Decoction group.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Pain relief rate in the oral cavity/oropharynx
Time Frame: 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).

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
RTOG score remission rate of RTOM
Time Frame: 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).
Evaluated at 2 weeks post-radiotherapy
3-month xerostomia relief rate
Time Frame: From enrollment (Day 0) through Month 3, spanning the entire radiotherapy treatment period.
To evaluate the proportion of patients who achieve a clinically significant improvement in subjectively reported xerostomia severity over the 3-month period, as assessed by the xerostomia questionnaire.
From enrollment (Day 0) through Month 3, spanning the entire radiotherapy treatment period.
