Qutob, A.F., Gue, S., Revesz, T., Logan, R.M., & Keefe, D. (2013). Prevention of oral mucositis in children receiving cancer therapy: A systematic review and evidence-based analysis. Oral Oncology, 49, 102–107.

To investigate, critically appraise, and rate the evidence regarding agents used for the prevention of mucositis in children

Databases searched included CINAHL, Cochrane library, Ovid MEDLINE, PubMed, BioMed Central, and other internet-based sources. A total of 19 databases were searched.

Search keywords were mucositis, stomatitis, oral inflammation, mouth mucosal inflammation, prophylaxis, management, and prevent; in addition to keywords to identify children and all types of cancer therapy.

Studies were included in the search if they

• Involved English-speaking children.
• Were clinical trials conducted on the prevention of oral mucositis during cancer therapy.

Studies were excluded if they

• Were not in English
• Did not involve children
• Involved only gastrointestinal mucositis.
• Involved treatment of mucositis rather than prevention.
• Were case studies or pilot studies.
• Were commentaries or letters to the editor.
• Involved sample sizes of less than 20 patients.

• The total number of references retrieved was 16,471.
• The authors evaluated the references using the Canadian Task Force on Preventive Health Care evidence-based guidelines.

• The final number of studies was 27. The sample range across studies was not reported.
• Other than inclusion of pediatric cases, no other characteristics were described.

• Patients were undergoing the active antitumor treatment phase of care.
• The study has clinical applicability for pediatrics.

• The studies involved the following interventions.
  • Oral care protocols (n = 5)
  • Chlorhexidine mouthwash (n = 7) 
  • Benzydamine mouthwash (n = 1)
  • Iseganan mouthwash (n = 1),
  • Granulocyte macrophage-colony stimulating factor (GM-CSF) mouthwash (n = 2)
  • Oral glutamine (n = 2)
  • Enteral glutamine (n = 1)
  • Oral propantheline and cryotherapy (n = 1)
  • Oral cryotherapy (n = 1)
  • Oral sucralfate suspension (n = 1)
  • Prostaglandin E2 tablets (n = 1)
  • Chewing gum (n = 1)
  • Laser therapy (n = 3). 
• Good evidential support was found for the use of oral care protocols. Fair support was found for the use of chlorhexidine with some mixed results.
• Only one article was found that studied benzydamine, CSF, and iseganan. The evidence was deemed insufficient to make a recommendation. 
• Good evidential support was found against the use of sucralfate and prostaglandin E2 tablets.
• Evidence regarding laser use and oral and enteral glutamine were mixed.

The authors concluded that oral care protocols should be used; oral sucralfate suspension, prostaglandin E2, and GM-CSF mouthwash should not be considered based on current evidence; and chlorhexidine (without use as part of an oral care protocol), laser therapy, and glutamine should not be considered because of conflicting evidence.

• No disease or treatment factors were reported or considered in the analysis. 
• Some interventions were evaluated in only one study.
• The quality of the evidence in general was highly variable.
• No information was provided on how the outcome for mucositis was measured in the included studies.
• The authors recommendations suggest no use of a specific intervention if findings were conflicting, which assumes that insufficient evidence of effectiveness is equivalent to ineffectiveness.

Findings provide further support for use of oral care protocols. Results provided no other useful recommendations for preventive therapies but identified the need for further research in this area.
