Clinical practice guidelines for the prevention and treatment of cancer therapy-induced oral and gastrointestinal mucositis.

Oral and gastrointestinal (GI) mucositis can affect up to 100% of patients undergoing high‐dose chemotherapy and hematopoietic stem cell transplantation, 80% of patients with malignancies of the head and neck receiving radiotherapy, and a wide range of patients receiving chemotherapy. Alimentary track mucositis increases mortality and morbidity and contributes to rising health care costs. Consequently, the Multinational Association of Supportive Care in Cancer and the International Society for Oral Oncology assembled an expert panel to evaluate the literature and to create evidence‐based guidelines for preventing, evaluating, and treating mucositis.

Updated clinical practice guidelines for the prevention and treatment of mucositis

Considerable progress in research and clinical application has been made since the original guidelines for managing mucositis in cancer patients were published in 2004, and the first active drug for the prevention and treatment of this condition has been approved by the United States Food and Drug Administration and other regulatory agencies in Europe and Australia. These changes necessitate an updated review of the literature and guidelines. Panel members reviewed the biomedical literature on mucositis published in English between January 2002 and May 2005 and reached a consensus based on the criteria of the American Society of Clinical Oncology. Changes in the guidelines included recommendations for the use of palifermin for oral mucositis associated with stem cell transplantation, amifostine for radiation proctitis, and cryotherapy for mucositis associated with high‐dose melphalan. Recommendations against specific practices were introduced: Systemic glutamine was not recommended for the prevention of gastrointestinal mucositis, and sucralfate and antimicrobial lozenges were not recommended for radiation‐induced oral mucositis. Furthermore, new guidelines suggested that granulocyte–macrophage‐colony stimulating factor mouthwashes not be used for oral mucositis prevention in the transplantation population. Advances in mucositis treatment and research have been complemented by an increased rate of publication on mucosal injury in cancer. However, additional and sustained efforts will be required to gain a fuller understanding of the pathobiology, impact on overall patient status, optimal therapeutic strategies, and improved educational programs for health professionals, patients, and caregivers. These efforts are likely to have significant clinical and economic impact on the treatment of cancer patients. Cancer 2007;109:820–31.

MASCC/ISOO clinical practice guidelines for the management of mucositis secondary to cancer therapy

Mucositis 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.

Validation of a new scoring system for the assessment of clinical trial research of oral mucositis induced by radiation or chemotherapy

An impediment to mucositis research has been the lack of an accepted, validated scoring system. The objective of this study was to design, test, and validate a new scoring system for mucositis that can be used easily, is reproducible, and provides an accurate system for research applications.

Low energy Helium-Neon laser in the prevention of oral mucositis in patients undergoing bone marrow transplant: Results of a double blind randomized trial

PURPOSE To evaluate the efficiency of Helium-Neon (He-Ne) laser in the prevention of oral mucositis induced by high dose chemoradiotherapy before autologous bone marrow transplantation (BMT). METHODS AND MATERIALS Between 1993 and 1995, 30 consecutive patients receiving an autologous peripheral stem-cell or bone marrow transplant (BMT) after high dose chemoradiotherapy were randomized to possibly receive prophylactic laser to the oral mucosa after giving informed consent. Chemotherapy consisted of cyclophosphamide, 60 mg/kg intravenously (I.V.) on day (d)-5 and d-4 in 27 cases, or melphalan 140 mg/kg I.V. on d-4 in three cases. Total body irradiation (TBI) consisted of 12 Gy midplane dose in six fractions (4 Gy/day for three days). He-Ne laser (632.8 nm wavelength, power 60 mW) applications were performed daily from d-5 to d-1 on five anatomic sites of the oral mucosa. Oral examination was performed daily from d0 to d + 20. Mucositis was scored according to an oral exam guide with a 16 item scale of which four were assessed by the patients themselves. Mean daily self assessment scores for oral pain, ability to swallow and oral dryness were measured. A daily mucositis index (DMI) and a cumulative oral mucositis score (COMS) were established. Requirement for narcotics and parenteral nutrition was recorded. RESULTS The COMS was significantly reduced among laser treated (L+) patients (p = 0.04). The improvement of DMI in L+ patients was also statistically significant (p < 0.05) from d + 2 to d + 7. Occurrence and duration of grade III oral mucositis were reduced in L+ patients (p = 0.01). Laser applications reduced oral pain as assessed by patients (p = 0.05) and L+ patients required less morphine (p = 0.05). Xerostomia and ability to swallow were improved among the L+ patients (p = 0.005 and p = 0.01, respectively). Requirement for parenteral nutrition was not reduced (p = NS). CONCLUSION Helium-Neon laser treatment was well tolerated, feasible in all cases, and reduced high dose chemoradiotherapy-induced oral mucositis. Optimal laser treatment schedules still needs to be defined.

Risk factors for ulcerative oral mucositis in cancer patients: unanswered questions

A multitude of laboratory and clinical research studies of ulcerative oral mucositis induced by cytotoxic cancer therapies have been reported during the past decade. However, a comprehensive understanding of oral mucositis pathogenesis, together with a clear definition of risk factors for development and severity of the lesion, remain under investigation. The literature presents sometimes divergent data regarding these issues, which in turn restrict efforts to develop a unified approach for management of this morbid condition. The current review summarizes these controversies and highlights the need for strategies for stratification of patients enrolled in clinical trials, in relation to both pathophysiologic and associated risk factors.

Benzydamine HCl for prophylaxis of radiation-induced oral mucositis

Benzydamine was evaluated in patients with head and neck carcinoma for treatment of radiation‐induced oral mucositis, a frequent complication of radiation therapy (RT) for which there is no predictable therapy or preventive treatment currently available.

Helium-neon laser effects on conditioning-induced oral mucositis in bone marrow transplantation patients

Background. Oral mucositis is a common complication of bone marrow transplantation (BMT) conditioning therapy. Sequelae consist of increased risk for infection, moderate to severe pain, compromised oral function, and bleeding. This study investigated helium‐neon laser treatment for prevention of conditioning‐induced oral mucositis in BMT patients. Patterns and severity of mucositis for specific conditioning drug regimens also were analyzed.

Management of oral and gastrointestinal mucositis: ESMO Clinical Practice Guidelines.

Oral and gastrointestinal mucositis due to cancer therapies such as high-dose chemotherapy and/or radiation continues to be an important clinical problem. Fortunately, there have been strategic advances over the past decade relative to understanding the molecular basis of the injury, opportunities for development of drugs and devices to prevent or treat the toxicity. The guidelines are almost unchanged from the version published in the 2010 Annals of Oncology.

Randomized, placebo-controlled trial of Saforis for prevention and treatment of oral mucositis in breast cancer patients receiving anthracycline-based chemotherapy.

Oral mucositis (OM) is a frequent complication of mucotoxic cancer therapy, causing significant oral pain, increased infection risk, and impaired functioning. The efficacy and safety of Saforis (glutamine) powder in UpTec for oral suspension was evaluated for the prevention and treatment of OM.
