Overview
Brief Summary
To explore the efficacy of Houyanqing Oral Liquid combined with conventional treatment in preventing and treating radiation-induced oral mucositis, so as to improve the quality of life of nasopharyngeal carcinoma patients received radiotherapy.
Detailed Description
Nasopharyngeal carcinoma (NPC) is a highly prevalent malignant tumor in China. Radical radiotherapy serves as its core treatment modality, yet radiation-induced oral mucositis (RIOM) is the most common adverse reaction of radiotherapy, with an incidence rate as high as 85%-100%, among which 34% of patients develop grade 3-4 mucositis. RIOM can cause oral pain, ulcers, and dysphagia, which not only severely reduce patients' quality of life but also may lead to radiotherapy interruption, increased infection risk, and elevated treatment costs. Therefore, the prevention and treatment of RIOM are of great significance.
At present, conventional clinical prevention and treatment methods include oral hygiene maintenance, epithelial repair-promoting drugs (e.g., recombinant human epidermal growth factor spray, sodium aescinate for injection), and symptomatic supportive care, but there is no universally recognized standard regimen. Houyanqing Oral Liquid is a traditional Chinese medicine preparation composed of Achyranthes aspera L., Kalimeris indica (L.) Sch.-Bip., Plantago asiatica L., and Carpesium abrotanoides L. It possesses the effects of clearing heat and detoxifying, relieving sore throat and pain. Previous studies have confirmed that it exhibits significant efficacy in anti-inflammation, bacteriostasis, and mucosal injury repair, which can shorten the course of oral ulcers and reduce the recurrence rate.
This study intends to conduct a randomized controlled clinical trial to compare the efficacy of Houyanqing Oral Liquid combined with conventional treatment versus conventional treatment alone in preventing RIOM in NPC patients. It aims to verify the advantages of the combined regimen in reducing the incidence of ≥ grade II RIOM, delaying the onset time, alleviating the severity of injury, and improving patients' quality of life, so as to provide a more effective and safe prevention and treatment strategy for RIOM in clinical practice.

Arms & Interventions
Houyanqing Oral Liquid combined with Conventional Treatment
This arm involves Houyanqing Oral Liquid combined with conventional treatment for preventing radiation-induced oral mucositis (RIOM) in nasopharyngeal carcinoma patients receiving radical radiotherapy. Specific interventions include: 1) Houyanqing Oral Liquid administration before and during radiotherapy; 2) Conventional treatment (same as the control arm): oral hygiene management, epithelial repair promotion, and symptomatic support therapy; 3) Radical radiotherapy (conventional fractionation). The aim is to evaluate the effect of this combined regimen on reducing RIOM severity.
Intervention: Houyanqing Oral Liquid (Drug)

Conventional Treatment
This arm consists of conventional treatment for preventing radiation-induced oral mucositis (RIOM) in nasopharyngeal carcinoma patients undergoing radical radiotherapy. Specific interventions include: 1) Oral hygiene management; 2) Epithelial repair promotion; 3) Symptomatic support . Patients in this arm will receive radical radiotherapy (conventional fractionation) but will not be administered Houyanqing Oral Liquid.
Intervention: Conventional Treatment for Radiation-Induced Oral Mucositis (Other)
Outcomes
Primary Outcomes
Incidence of ≥ Grade II radiation-induced oral mucositis
Time Frame: From the start of radical radiotherapy to the 3 months after the completion of radiotherapy
The proportion of patients in the group who develop Grade II or above radiation-induced oral mucositis from the start of radiotherapy. The degree of oral mucosal damage is evaluated according to the Radiation Therapy Oncology Group/European Organization for Research and Treatment of Cancer (RTOG/EORTC) diagnostic and grading criteria for radiation-induced oral mucositis.
Secondary Outcomes
- Time to onset of Grade II or above radiation-induced oral mucositis(From the start of radical radiotherapy to the 3 months after the completion of radiotherapy.)
- Cumulative radiotherapy dose at onset of Grade II or above radiation-induced oral mucositis(From the start of radical radiotherapy to the 3 months after the completion of radiotherapy.)
- Remission rate of Grade II or above radiation-induced oral mucositis(From the first occurrence of Grade II or above radiation-induced oral mucositis to 3 months after the completion of radiotherapy)
- Complete remission rate of radiation-induced oral mucositis(From the first occurrence of Grade II or above radiation-induced oral mucositis to 3 months after the completion of radiotherapy)
- Remission time of Grade II or above radiation-induced oral mucositis(From the first occurrence of Grade II or above radiation-induced oral mucositis to 3 months after the completion of radiotherapy.)
- Complete remission time of radiation-induced oral mucositis(From the first occurrence of Grade II or above radiation-induced oral mucositis to 3 months after the completion of radiotherapy.)
