3 1. PRINCIPLES OF ORAL MUCOSITIS 1.1. Mucositis describes inflammation of the oral mucosa resulting from chemotherapeutic drugs or ionising radiation. It initially starts as erythema, progressing through to frank ulceration and necrosis as the severity of mucositis increases. It is commonly a dose limiting toxicity for cytotoxic agents and is a particular problem in the use of fluoropyrimidines, anthracyclines and folate-based drugs such as methotrexate. Radical radiotherapy treatments of the head and neck region that usually deliver a dose of Gray will result in significant mucositis, which starts to develop during the second week of radiotherapy and can last for 3-4 weeks once radiotherapy is completed Factors that increase the risk of mucositis include: Smoking throughout course of chemotherapy or radiotherapy Drinking alcohol throughout course of chemotherapy and radiotherapy Poor oral hygiene and pre-existing mouth damage Mucositis with previous cycle of treatment Previous gastritis Impaired immune status 1.3. Mucositis can be a difficult issue to manage as it causes significant pain, increases the risk of oral infections, can result in significant reductions in nutritional intake and may require delays or interruptions in a course of treatment. The National Cancer Institute Common Toxicity Criteria of Adverse Events (NCI CTCAE) grades mucositis according to its severity based on clinical examination findings and functional/symptom assessment. Grading for oral mucositis is shown in the table below. There are separate grading definitions for laryngeal, pharyngeal and tracheal mucositis. Page 3 of 8

4 NCI CTCAE Version 4 Grade 0 Grade 1 Grade 2 Grade 3 Grade 4 Grade 5 Normal mucosa, no symptoms Asymptomatic or mild symptoms; normal diet. Moderate pain; not interfering with oral intake; modified diet indicated. Severe pain; interfering with oral intake Life-threatening consequences; urgent intervention required Death 2. PREVENTION OF MUCOSITIS 2.1. General Advice. Patients can be directed to the appropriate Macmillan Cancer Support leaflets or the Side effects and symptoms section of the Macmillan website Patients should be encouraged to visit their dentist regularly. A visit before chemotherapy starts is advised to ensure that any oral hygiene issues have been addressed. Visits to a dental hygienist during treatment is not advised to avoid unnecessary trauma to the gums Prevention is based on good oral hygiene, use of non-alcohol based mouthwashes and simple analgesia. Ideally the aim is to reduce the risk of severe mucositis developing during chemotherapy. All patients should be advised on the need for good oral hygiene to stop smoking and reduce alcohol intake during their treatment. Patients should brush their teeth using a soft toothbrush and fluoride toothpaste twice daily. Toothbrushes should be replaced regularly to minimize infection risk. Patients should rinse their mouth with water after meals. Page 4 of 8

5 If conventional brushing of the teeth becomes too painful patients should use children s 6+ fluoride toothpaste or gel using a baby toothbrush. Dentures should be cleaned after each meal and left to soak in the patient s usual solution overnight. Patients may consider using normal saline or water mouthwashes regularly from the first day of their chemotherapy/radiotherapy as this may provide indirect benefits of reducing oral plaque and controlling the development of candidiasis and gingivitis. Patients should maintain adequate oral intake of fluids and ensure they remain well hydrated Guidance specifically related to fluorouracil (5FU) bolus chemotherapy. Cryotherapy can be used to try and reduce the incidence of 5- fluorouracil induced mucositis. Patients are advised to chew on ice cubes/chips for 30 minutes before their 5-fluorouracil bolus injection. It is thought this reduces the vascular delivery of the cytotoxic to the oral epithelium and thereby ameliorates its mucosal side effects. Its use must be discussed with the consultant in charge of the patient s care, prior to initiation Prevention of oral mucositis in radiotherapy patients. In addition to the above measures, for patients receiving radiotherapy to the head and neck consider caphosol four times a day, available as an oral rinse or dispersible tablets. This is to lubricate the mouth and tongue and maintains a healthy oral cavity by promoting mucosal repair. Directions for oral rinse: 15ml of the phosphate solution (Solution A) should be mixed with 15ml of the calcium solution (Solution B) and rinsed round the mouth for 1 minute and spat out. Directions for dispersible tablets: Place one tablet into 50 ml of water and wait for the complete dissolution of the tablet. Swish in the mouth thoroughly for 1 min with half of the solution and spit out. Repeat with the remaining half of the solution and spit out. Page 5 of 8

6 3. TREATMENT OF MUCOSITIS Check if there is any evidence of infection if infection is present see section below on oral infection. Assess severity of mucositis and treat accordingly Grade 1-2 mucositis Consider regular normal saline or water mouthwashes 10ml QDS. It is important to encourage vigorous rinsing using a ballooning and sucking motion of the cheeks for at least 30 seconds; this action removes loose debris from the teeth. There is no clinical benefit in using a commercial product, however if the patient prefers this an alcohol free preparation should be used. In chemotherapy patients there is no reliable evidence to show that chlorhexidine mouthwash is superior to saline or water mouthwashes, and therefore should be avoided. Apply Bonjela PRN or Orabase to mouth ulcers, if not contraindicated. Ensure patient is receiving regular systemic analgesia such as paracetamol 1g four times a day; oral opioid analgesia may be necessary. Consider benzdyamine mouthwash (Difflam ), 10ml QDS or antacid and oxcetacaine suspension or 5-10ml, sipped slowly, QDS before meals to improve local analgesia within the oral cavity and pharynx. Patients should be advised oxcetacaine and antacid contains a local anaesthetic and therefore should avoid hot food immediately following its use. Consider increasing folinic acid rescue for methotrexate induced mucositis. Closely monitor nutritional status and hydration and consider hospital admission for symptom management if mucositis worsening or patient not able to maintain oral intake Grade 2 mucositis In addition to the measures above Caphosol and either Gelclair or Episil may be used: o Caphosol.four to ten times daily. Available as an oral rinse and dispersible tablets. Directions for oral rinse: 15ml of the phosphate solution (Solution A) should be mixed with 15ml of the calcium solution (Solution B) and rinsed round the mouth for 1 minute and spat out.

7 Directions for dispersible tablets: Place one tablet into 50 ml of water and wait for the complete dissolution of the tablet. Swish in the mouth thoroughly for 1 min with half of the solution and spit out. Repeat with the remaining half of the solution and spit out. o Gelclair. One sachet used TDS, or as needed, from the onset of symptoms until resolution. Gelclair may be mixed with 40ml of water and rinsed around mouth or applied neat, directly to the oral mucosa. Gelclair forms a bioprotective barrier that adheres to the oropharyngeal mucosa and covers exposed nerve endings and reduces pain. o Episil Spray on affected areas of the mucosa 2-3 times a day, or as needed, from the onset of symptoms until resolution. Episil adheres to the oral mucosa and forms a protective film that acts as a mechanical barrier to provide pain relief. Local application of lidocaine and chlorhexidine gel (Instillagel ) to the anterior oral cavity (i.e. local tongue ulceration and lips) can be used in head and neck patients on consultant recommendation only. It should be applied directly to the affected area. This is an unlicensed indication for Instillagel. Barrier and local application preparations should be applied following other mouthwashes to ensure that they are in contact with the affected area for the greatest amount of time possible Grade 3 mucositis and above Consider admitting the patient to hospital if pain control, hydration and nutritional support cannot be adequately managed as an outpatient. Review compliance with oral medication. If patient is unable to swallow capsules/tablets, consider liquid/soluble preparations where possible. Discuss whether to make changes to treatment schedules and chemotherapy doses with a registrar or consultant. Consider dose reduction for the next cycle of chemotherapy. Assess for oral candidiasis, as high risk of infection. If candida is present, treat with systemic therapies as outlined below, as topical therapies are not effective. Mouthcare as for grade 1-2 mucositis. Discuss with a senior regarding appropriateness of enteral or parenteral feeding and patient to be reviewed by dietician. Page 7 of 8

8 3.4. Treatment of oral infection Continue mouthwashes and analgesia Fungal infection: Initiate fluconazole 50mg OD orally for 7-14 days, increase to 100mg OD if immunocompromised. Consider syrup formulation if patient unable to swallow capsules. Seek microbiology advice if fluconazole not effective. Consider prophylactic antifungals if repeated oral candidiasis. Monitor liver function tests while patient on fluconazole Herpes infection: Initiate aciclovir 200mg 5 times a day, orally for 5 days, increase dose to 400mg if immunocompromised. Consider prophylactic antivirals in repeated herpes infection In grade 3 mucositis treat according to type of infection with: Fluconazole 100mg OD, orally (or 100mg OD IV) for candidiasis. For resistant oral candidiasis seek advice from microbiology. Aciclovir 200mg 5 times a day orally (or 5mg/kg TDS IV) for viral infections, increasing to 400mg 5 times a day orally (or 10mg/kg TDS IV) if immunocompromised. Metronidazole 400mg TDS, orally (or 500mg TDS IV) for anaerobic bacterial infections. Page 8 of 8
