Prevention and Management Tips for Radiation-Induced Oral Mucositis in Head and Neck Cancer

What is radiation-induced mucositis in head and neck cancer?

Radiation-induced mucositis in head and neck cancer​​, commonly referred to as ​​mucositis​​, is an acute mucosal injury caused by radiation therapy, encompassing conditions such as ​​oral mucositis​​, ​​pharyngeal mucositis​​, and ​​laryngeal mucositis​​.

2.Is this type of mucositis common?

Over 80% of head and neck cancer patients undergoing radiotherapy develop mucositis​​, with ​​oral mucositis being the most prevalent form​​. Approximately ​​half of these patients experience severe mucositis​​.

3.Who is at higher risk of developing mucositis?

The occurrence of mucositis is primarily influenced by:​​​​Radiation dose​​，​​Treatment site​​，Concurrent use of chemotherapy or targeted therapy​.

Additional High-Risk Groups:​​Malnourished patients, smokers, and individuals with poor oral hygiene not only ​​have a higher incidence of mucositis​​, but also tend to develop ​​more severe cases​​.

​​Clinical Manifestations:​​Mucositis typically manifests as ​​toothache, xerostomia (dry mouth), dysphagia, and taste dysfunction​​. Systemic symptoms such as ​​fever, fatigue, and inflammatory responses​​ may also occur. In severe cases, ​​oral mucositis can necessitate radiotherapy interruption​​, compromising treatment efficacy.

5.Since oral care helps reduce the incidence of mucositis, how should patients maintain proper oral hygiene during radiotherapy?

Recommended Oral Care Protocol:​​Gently brush teeth, gums, and tongue with a ​​soft-bristled toothbrush​​ after every meal and before bedtime, thoroughly rinse the toothbrush with water after each use

​​(1) During Radiotherapy: Contraindicated Oral Care Tools​​

• ​​Avoid dental floss, toothpicks, and oral irrigators​​

• Rationale: These may cause microtrauma to irradiated mucosa, increasing infection risks

​​(2) Denture Care During Radiotherapy​​

• Ensure ​​optimal denture fit​​ to prevent mucosal irritation

• ​​Post-meal care protocol​​: Rinse dentures thoroughly after every meal.Perform ​​deep cleaning​​ ≥2 times daily with denture-specific solutions

• Maintain ​​oral rinsing routine​​: Use plain water for post-meal rinsing (≥4 times/day), consider ​​alkaline rinses​​ (pH 8.0-8.5) for mucosal protection.

​​(3) Substance Cessation Mandate​​

• ​​Complete abstinence required​​:Tobacco products (including ​​e-cigarettes/vaping​​), all alcoholic beverages.

• Rationale:

Smoking ​​delays mucosal healing​​ by 40-60% (RTOG 0225 data)

Alcohol ​​potentiates radiation toxicity​​ to mucosa

6.Are there any dietary precautions to take?

(1) Good nutrition can help the body resist infections and enhance the repair of mucosal tissues.

(2) Avoid hot, rough, or hard foods, and refrain from eating spicy, overly salty, or highly acidic foods.

(3) Try to eat soft, small, and easy-to-swallow foods, and chew slowly.

(4) Consume light yet nutritious foods, opting for soft or liquid foods that are high in calories, protein, and vitamins, such as eggs, milk, meat, fresh vegetables, and fruits, to ensure adequate nutrition during treatment.
