BACKGROUNDMucositis is a highly significant, and sometimes dose‐limiting, toxicity of cancer therapy. The goal of this systematic review was to update the Multinational Association of Supportive Care in Cancer and International Society of Oral Oncology (MASCC/ISOO) Clinical Practice Guidelines for mucositis.METHODSA literature search was conducted to identify eligible published articles, based on predefined inclusion/exclusion criteria. Each article was independently reviewed by 2 reviewers. Studies were rated according to the presence of major and minor flaws as per previously published criteria. The body of evidence for each intervention, in each treatment setting, was assigned a level of evidence, based on previously published criteria. Guidelines were developed based on the level of evidence, with 3 possible guideline determinations: recommendation, suggestion, or no guideline possible.RESULTSThe literature search identified 8279 papers, 1032 of which were retrieved for detailed evaluation based on titles and abstracts. Of these, 570 qualified for final inclusion in the systematic reviews. Sixteen new guidelines were developed for or against the use of various interventions in specific treatment settings. In total, the MASCC/ISOO Mucositis Guidelines now include 32 guidelines: 22 for oral mucositis and 10 for gastrointestinal mucositis. This article describes these updated guidelines.CONCLUSIONSThe updated MASCC/ISOO Clinical Practice Guidelines for mucositis will help clinicians provide evidence‐based management of mucositis secondary to cancer therapy.

Answer questions and earn CME/CNEOral complications resulting from cancer and cancer therapies cause acute and late toxicities that may be underreported, underrecognized, and undertreated. Recent advances in cancer treatment have led to changes in the incidence, nature, and severity of oral complications. As the number of survivors increases, it is becoming increasingly recognized that the aggressive management of oral toxicities is needed to ensure optimal long‐term oral health and general well‐being. Advances in care have had an impact on previously recognized oral complications and are leading to newly recognized adverse effects. Here, the authors briefly review advances in cancer therapy, including recent advances in surgery, oral care, radiation therapy, hematopoietic cell transplantation, and medical oncology; describe how these advances affect oral health; and discuss the frequent and/or severe oral health complications associated with cancer and cancer treatment and their effect upon long‐term health. Although some of the acute oral toxicities of cancer therapies may be reduced, they remain essentially unavoidable. The significant impact of long‐term complications requires increased awareness and recognition to promote prevention and appropriate intervention. It is therefore important for the primary oncologist to be aware of these complications so that appropriate measures can be implemented in a timely manner. Prevention and management is best provided via multidisciplinary health care teams, which must be integrated and communicate effectively in order to provide the best patient care in a coordinated manner at the appropriate time.

BACKGROUND. The risk, severity, and patient‐reported outcomes of radiation‐induced mucositis among head and neck cancer patients were prospectively estimated. METHODS. A validated, patient‐reported questionnaire (OMDQ), the FACT quality of life (QOL), and the Functional Assessment of Chronic Illness Therapy (FACIT) fatigue scales were used to measure mucositis (reported as mouth and throat soreness), daily functioning, and use of analgesics. Patients were studied before radiotherapy (RT), daily during RT, and for 4 weeks after RT. RESULTS. Contrary to previous reports, the risk of mucositis was virtually identical in the 126 patients with oral cavity or oropharynx tumors (99% overall; 85% grade 3‐4) compared with 65 patients with tumors of the larynx or hypopharynx (98% overall; 77% grade 3‐4). The mean QOL score decreased significantly during RT, from 85.1 at baseline to 69.0 at Week 6, corresponding with the peak of mucositis severity. The mean functional status score decreased by 33% from 18.3 at baseline to 12.3 at Week 6. The impact of mucositis on QOL was proportional to its severity, although even a score of 1 or 2 (mild or moderate) was associated with a significant reduction in QOL (from 93.6 at baseline to 74.7 at Week 6). Despite increases in analgesic use from 34% at baseline to 80% at Week 6, mean mucositis scores exceeded 2.5 at Week 6. CONCLUSIONS. Mucositis occurs among virtually all patients who are undergoing radiation treatment of head and neck cancers. The detrimental effects on QOL and functional status are significant, and opioid analgesia provides inadequate relief. Preventive rather than symptom palliation measures are needed.

Background Mucositis is a significant toxicity of cancer therapy with numerous systemic sequelae. The goal of this systematic review was to update the Multinational Association of Supportive Care in Cancer and International Society of Oral Oncology (MASCC/ISOO) Clinical Practice Guidelines for the management of mucositis. Methods The literature was reviewed systematically to identify interventions for mucositis. Studies were rated according to the presence of major and minor flaws according to previously published criteria. The body of evidence for each intervention and in each treatment setting was assigned a level of evidence based on previously published criteria. Guidelines were developed based on the level of evidence, with 3 possible guideline determinations: recommendation, suggestion, or no guideline possible. Results The guideline covers evidence from 1197 publications related to oral or gastrointestinal mucositis. Thirteen new guidelines were developed for or against the use of various interventions in specific treatment settings, and 11 previous guidelines were confirmed after aa review of new evidence. Thirteen previously established guidelines were carried over because there was no new evidence for these interventions. Conclusions The updated MASCC/ISOO Clinical Practice Guidelines for mucositis provide professional health caregivers with a clinical setting‐specific, evidence‐based tool to help with the management of mucositis in patients who have cancer.
