Prevention and Treatment of Radiation-Induced Oral Mucositis in NPC With Houyanqing Oral Liquid

Официальное название

A Randomized Controlled Study of Houyanqing Oral Liquid Combined With Conventional Treatment Versus Conventional Treatment Alone for Preventing and Treating Radiation-Induced Oral Mucositis in Nasopharyngeal Carcinoma

Обзор

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.

Подробное описание

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.

Вмешательства

• Препарат Houyanqing Oral Liquid
  Houyanqing Oral Liquid is a Chinese herbal preparation formulated with Achyranthes aspera L., Kalimeris indica (L.) Sch.-Bip., Plantago asiatica L., and Carpesium abrotanoides L.. For this study, it is used in nasopharyngeal carcinoma patients receiving radical radiotherapy: the dosage is 10mL per administration, 4 times daily. The medication is initiated prior to radiotherapy and continued until the completion of radiotherapy, with the purpose of preventing and treating radiation-induced oral m
• Другое Conventional Treatment for Radiation-Induced Oral Mucositis
  This intervention refers to the conventional management measures for radiation-induced oral mucositis (RIOM) in nasopharyngeal carcinoma patients undergoing radical radiotherapy, including three modules: 1) Oral hygiene management; 2) Epithelial repair promotion; 3) Symptomatic support. These measures are implemented throughout the radiotherapy period to alleviate RIOM-related symptoms.
