Chemotherapy-Induced Oral Mucositis

Practice Essentials

Oral mucositis is a common complication of cancer chemotherapy. It begins 5-10 days after the initiation of chemotherapy and lasts 7-14 days. Chemotherapy-induced oral mucositis causes the mucosal lining of the mouth to atrophy and break down, forming ulcers. See the image below.

Signs and symptoms

Patients typically experience the following:

Oral pain and burning

Erythema and ulcerations

Difficulty eating, drinking, and speaking

Difficulty with mouth care regimens

See Clinical Presentation for more detail.

Diagnosis

The diagnosis of chemotherapy-induced oral mucositis is based on clinical findings and the chronology of the development of lesions.

Cultures should be performed if erythema and ulcers are located on the hard palate, attached gingiva, or dorsum of the tongue. Biopsy may be indicated, but it is not routinely necessary for diagnosis.

The two most commonly used scales for grading oral mucositis are the following:

World Health Organization (WHO) Oral Toxicity Scale: Combines both objective and functional elements into a single score

National Cancer Institute Common Toxicity Criteria (NCI CTC): Scores functional elements only

See Workup for more detail.

Management

The five main approaches to managing oral mucositis are as follows:

Oral debridement (eg, brushing, toothettes); mucolytic agents, such as Alkalol, help dislodge dried secretions

Oral decontamination, including antibacterial and antifungal rinses

Topical and systemic pain management, such as 2% viscous lidocaine, magic mouthwash preparations, and topical morphine solution may be considered

Prophylaxis, such as ice-chip cryotherapy or Palifermin (keratinocyte growth factor, FDA approved for mucositis prevention in hematopoietic cell transplantation)

Low-level laser therapy (photobiomodulation)

See Treatment and Medication for more detail.
