Oral Health Maintenance in Head and Neck Cancer Patients A Peer-Reviewed Publication Written by Kathryn Gilliam, RDH, BA Abstract Many head and neck cancer patients are not treated in large cancer centers that have dental oncologists as a part of the cancer care team. They are being treated in smaller cancer centers or private oncology practices where there may not be a focus on oral health. These people are coming to their regular dental offices for care, often with side effects of their cancer treatment. Standards and protocols are detailed for use in a general dental practice. This course consolidates current recommendations into specific protocols that are easily implemented in the general dental practice. The goal is to give dentists and dental hygienists the confidence to treat head and neck cancer patients effectively and with concern for the whole person who is in need of special care at this vulnerable time. Educational Objectives: At the conclusion of this educational activity participants will be able to: 1. Recognize common oral complications resulting from radiation therapy, chemotherapy, and other cancer treatments. 2. Identify when it is considered safe to treat a patient undergoing cancer treatment. 3. Develop an individual plan for treatment of various oral complications to assist in the supportive care of the patient undergoing cancer therapy. 4. Recognize the dental professional’s responsibility to protect the oral health of the patient undergoing treatment for head and neck cancer and the need to be an advocate for oral care during this critical time in the patient’s life.

Abstract Many head and neck cancer patients are not treated in large cancer centers that have dental oncologists as a part of the cancer care team. They are being treated in smaller cancer centers or private oncology practices where there may not be a focus on oral health. These people are coming to their regular dental offices for care, often with side effects of their cancer treatment. Standards and protocols are detailed for use in a general dental practice.

The goal is to give dentists and dental hygienists the confidence to treat head and neck cancer patients effectively and with concern for the whole person who is in need of special care at this vulnerable time. Introduction The majority of articles or continuing education courses dealing with cancer begin with statistics. Statistics certainly have a place, but they can also overshadow the fact that every number actually represents an individual person: a person who may be afraid, a person who may be in pain, or a person who may be looking to you, a healthcare provider, to offer relief. This course is intended to prepare you to offer aid to the people in your practice who are undergoing some of the most traumatic experiences of their lives and who are literally fighting for their lives. A few of those statistics Every year, 1.2 million Americans are diagnosed with some form of cancer. In 2013, there were 41,380 people diagnosed with oral and pharyngeal cancer and 7,890 people died of head and neck cancer.1 Head and neck squamous cell carcinomas, which include cancers of the oral cavity, oropharynx and larynx, are the sixth most common cancers worldwide with 633,000 cases diagnosed each year, resulting in 355,000 deaths annually.2 Although overall US cancer death rates continue to decline, the incidence of HPV-related oropharyngeal cancers are increasing according to a 2013 annual report on the status of cancer in the United States.3 Studies indicate that the majority of head and neck cancer patients will suffer from at least some oral complications of their radiation and chemotherapy treatments.4 Part of the team As dental healthcare providers, it is our obligation to provide assessment, prevention and treatment to minimize the negative effects of cancer therapy, improve the quality of life and possibly save the life of the head and neck oncology patient. The emotional impact of a cancer diagnosis and treatment options and decisions can overwhelm the cancer patient and family. It is natural to want to begin cancer treatment without delay. Dental concerns seem minimally important compared to the life and death magnitude of cancer. The dental team must become part of the cancer care team to assist the patient and family through the maze of treatment coordination so that dental concerns can be addressed and the potential negative oral effects of cancer treatment can be prevented or minimized. The prevention and management of oral complications of cancer therapy is a topic addressed in many articles but acknowledged to be lacking in evidence-based research.5 This course is intended to compile the best evidence-based information and present practical clinical knowledge for the dental healthcare provider who is increasingly being asked to care for head and neck cancer patients in the general dental setting. There is a tendency to defer to the oncologist, but not all oncologists are focused on the importance of a dental health evaluation before the start of cancer treatment, or the importance of supportive dental care during and after cancer treatment. That is why it is crucial for the general dental team to recognize its place on the cancer patient’s care team and to effectively care for the head and neck cancer patient and family before, during and after cancer therapy. Three phases of dental care of the head and neck cancer patient 1. Assessment before the start of cancer treatment 2. Supportive management during cancer treatment, including management of oral complications 3. Maintenance treatment following the conclusion of cancer treatment Pre-treatment assessment The most important dental visit for a patient diagnosed with any type of cancer is the pre-cancer treatment dental assessment. Poor oral health has been associated with an increased incidence and severity of oral complications. 2www.ineedce.com This has influenced an aggressive approach to stabilizing oral health as much as possible before the start of cancer treatment.6 According to the National Cancer Institute, most oncologists assert that delay in treatment is the main reason they do not refer their patients for a pre-treatment dental evaluation.7 It is crucial, therefore, that general dental teams commit to seeing newly diagnosed cancer patients as soon as possible. Since time is critical for these patients, and generally not as urgent for other patients in our practices, an office policy regarding immediate scheduling for pre-treatment assessment of cancer patients is recommended. The focus of the pre-treatment examination is to determine the oral health status and to initiate necessary interventions that may reduce oral complications during and after cancer therapy.8 Ideally, any dental treatment performed should be scheduled to allow a minimum of 14 days of healing before the start of oncology treatment. Goals of pre-treatment dental examination • Provide prompt identification of existing infections or other problems. • Improve the likelihood the patient will tolerate the optimal schedule and dosage of cancer treatment. • Prevent, eliminate or reduce oral pain. • Minimize oral infections that could lead to potentially fatal systemic infections. • Reduce the risk and severity of oral complications. • Prevent or minimize complications that compromise nutrition. • Prevent or reduce a later incidence of bone necrosis. • Preserve or improve oral health. • Improve quality of life. Pre-treatment assessment The pre-treatment assessment should include the following: • Identify and treat sites of low grade and acute oral infections – Caries – Periodontal disease – Endodontic infection – Mucosal lesions (If the patient has a history of recurrent herpetic ulcers, discuss with the oncologist the benefit of prescribing a prophylactic systemic antiviral regimen that the patient will continue throughout the oncology treatment.) • Establish a schedule for dental treatment and begin at least 14 days before the start of cancer therapy to allow for healing. Postpone elective procedures until after the cancer treatment is complete and the oncologist clears the patient. www.ineedce.com • • • • • • • • • • Perform necessary oral surgical procedures at least 14 days before the initiation of radiation treatment. Radiation patients, especially those with head and neck cancer, may only be able to have dental surgery during this pre-treatment phase due to the potential for osteoradionecrosis following irradiation of bone. In adults, extract teeth that may pose a future problem or are non-restorable to prevent later extraction-related osteoradionecrosis. In children, extract loose primary teeth and teeth that are expected to exfoliate during later treatment. Eliminate potential sources of oral trauma and irritation such as orthodontic bands and brackets, ill-fitting dentures, and other appliances. Orthodontic appliances should be removed before the start of cancer treatment if highly stomatotoxic chemotherapy is planned or if the appliances will be in the field of radiation. Before starting head and neck radiation, identify and treat all potential oral problems in the field of radiation. Request the planned area description and illustrations from the radiation oncologist. Common head and neck radiation fields are described and illustrated in the monograph, Oral Health in Cancer Therapy.9 Educate the patient regarding the critical nature of impeccable oral hygiene. –Establish a written home care plan for the patient and supply necessary implements, if possible. – Recommend a power toothbrush and demonstrate its proper usage. – Demonstrate proper flossing technique and the proper use of other interproximal cleaning devices. Fabricate custom fluoride trays and prescribe 1.1% neutral pH sodium fluoride gel aimed at prevention of demineralization and caries. –Be sure trays cover all tooth structures without irritating gingival or mucosal tissues. –Instruct the patient to use custom fluoride trays for five minutes a day beginning before the first radiation session and continuing indefinitely. Advise the patient to avoid alcohol and tobacco during cancer treatment. Schedule the patient for oral health maintenance procedures every 8 to 12 weeks during cancer treatment, as blood counts allow. –Following active radiation treatment, see the patient every 6 to 8 weeks for prophylaxis or periodontal maintenance procedures. –Gradually, as the patient’s health stabilizes, increase the time interval to three months. Advise the patient to report any adverse oral effects immediately so appropriate measures can be insti- 3 Table 1: Treatment with possible complication percentage 10 Treatment Regimen Anticipated Percentage of Complications Adjunctive chemotherapy 10 Primary chemotherapy 40 Hematopoietic stem cell transplantation* where myeloablative conditioning regimens** are used 80 Head and neck radiation therapy to fields involving the oral cavity 100 *Transplantation of blood cells that give rise to all other blood cells derived from bone marrow, peripheral blood or umbilical cord blood **Administration of high doses of chemotherapy or radiation therapy prior to bone marrow transplantation causing severe myelosuppression Table 2: Radiation induced oral complications Complication Acute Chronic Mucositis (mucosal inflammation and ulceration) X X Pain X X Xerostomia (salivary gland dysfunction/dry mouth) X X Dysgeusia (taste dysfunction) X X Infections X X Dental caries X X Dehydration and malnutrition (anorexia) X X Osteoradionecrosis (ORN) X X Dysphagia (swallowing difficulty) X X Trismus (mucosal fibrosis and atrophy) X Soft tissue necrosis X Dysphasia (speech disorders) X Psychosocial effects X tuted to ameliorate symptoms before they become so acute as to interfere with cancer treatment. Supportive dental care during cancer therapy During the course of cancer treatment, the dental team must maintain communication with the oncology team. Consult with the oncologist before any dental procedures, including routine prophylaxis or periodontal maintenance procedures. Ask the oncology team for the patient’s blood count after each appointment, which will determine when and if a patient can safely tolerate dental treatment. When the patient’s health is too fragile for dental procedures, supportive care can come in the form of home care recommendations and psychological and emotional support. The type of treatment the patient is receiving will determine the likelihood of experiencing oral complications (Table 1.) Radiation therapy Radiation therapy is used routinely in the treatment of head and neck cancers. It may be used as the primary treatment or as adjuvant therapy following surgery. It may be used alone or with chemotherapy. Radiation therapy is generally given once a day, five days a week. The radiation schedule is called “fractionation.” For advanced tumors, more aggressive schedules to intensify treatment are used and this is called accelerated fractionation or hyperfractionation. Most tumors of the head and neck are squamous cell carcinomas, which require high doses of radiation. Radiation doses for cancer treatment are measured in a unit called a gray (Gy), which is a measure of the amount of radiation energy absorbed by 1 kilogram of human tissue. Different doses of radiation are needed to kill different types of cancer cells. Oral complications of radiation therapy are related to the site radiated, the total radiation dose, the fractionation schedule, and integration with other therapies such as chemotherapy. Negative oral consequences of radiation treatment All patients who have undergone radiation therapy for cancer are at risk for oral complications, but head and neck cancer patients are a particular challenge regarding oral complications. The oral side effects of head and neck radiation are more predictable, more severe and can lead to permanent tissue changes. These changes can put the patient at a greater risk for serious chronic conditions than the oral complications typically associated with chemotherapy, which are usually of a shorter duration and usually less severe than those of radiation therapy.11 The effects of tumorcidal doses of radiation on oral tissues can cause a plethora of short and long term negative side effects that impair the quality of life. Radiation side effects are divided into acute and chronic types. Acute effects develop during the early phases of radiotherapy and continue into the immediate post-treatment period. Chronic effects can manifest from weeks to years after radiation treatment. The acute effects range from uncomfortable to intensely painful, but generally resolve in time. However, the severe and acute toxic effects on the oral mucosa can result in the need for treatment schedules to be modified so that oral lesions can resolve.12 In cases of severe oral involvement, the patient may no longer be able to continue with cancer treatment. Discontinuation of therapy can be life threatening. 4www.ineedce.com Chemotherapy The use of combined chemotherapy and radiation is now considered standard for most locally advanced tumors of the head and neck. The toxicities of the combined therapy are essentially the same as with radiation alone, but develop more rapidly and are typically more severe when they reach the maximum level of drug dosage.13 The goal of chemotherapy is to eradicate the rapidly growing tumor cells. Unfortunately, chemotherapy is also toxic to other rapidly growing cells, such as those of the bone marrow, hair and mucosa of the gastrointestinal tract, including the oral cavity. Negative oral consequences of chemotherapy • Direct cytotoxic effects of chemotherapy –Mucositis and ulceration of the lining of the oral mucosa. • Indirect cytotoxic effects of chemotherapy –Myelosuppression (condition in which bone marrow activity is decreased, resulting in fewer red blood cells, white blood cells and platelets) results in anemia (below normal red blood cell count), thrombocytopenia (below normal platelets), and leukopenia (below normal white blood cells). –Decreased platelet count is common in patients on chemotherapy. Patients are at risk for postoperative bleeding with dental surgery when the platelet count is below 75,000/mm3. Spontaneous mucosal bleeding can occur when the platelet count is below 20,000mm3. –Advise the oncologist of the potential for bacteremia and/or bleeding associated with proposed dental procedures during chemotherapy. • Infection –Infections in the oral cavity are associated with oral ulcers, periodontal disease, pulpal disease, pericoronal disease and sinus infections. –Fungal infections are also increased in these patients. Management of oral complications of head and neck cancer therapy Mucositis Oral mucositis is a common debilitating complication of cancer therapy, occurring in about 60% of patients. Oral mucositis describes inflammation of oral mucosa resulting from chemotherapeutic drugs or ionizing radiation. Mucositis typically manifests initially as erythema, with ulceration developing later. Acute mucositis results from the loss of squamous epithelial cells because of the radiation induced death of basal cells. This results in a decrease of epithelial cells. As therapy continues, cell regeneration often cannot keep up with the www.ineedce.com Table 3: Recommendation based on lab values 14 Lab Values Neutrophils (Absolute Neutrophil Count) Recommendation Obtain from CBC or from oncologist. >2,000/mm 3 No prophylactic antibiotics necessary for dental treatment. 1,000 mm 3 2,000/mm 3 AHA recommendations for prophylaxis with dental procedures. <1,000/mm 3 • IV Antibiotics before surgery. • Consult with oncologist. • No routine dental procedures.

In addition to direct tissue injury, the oral microbial flora is thought to contribute to radiation induced mucositis. Symptoms of radiation induced mucositis include intense pain, difficulty swallowing (dysphagia) and resulting anorexia and difficulty speaking. Chemotherapy induced mucositis results from the direct cytotoxic effects of the chemotherapeutic agents on the epithelial cells. Mucositis is common when chemotherapy is given in high doses and repeating schedules or when combined with radiation. Mucositis is the primary reason patients may need to stop chemotherapy. Clinical signs of oral mucositis are generally seen 5-10 days following the initiation of chemotherapy and last 7-14 days. Severity of mucositis coincides with the degree of neutropenia (low white blood cell count) and is typically most severe at the lowest value of the neutrophil count. Mucositis is usually self-limiting and heals within 2-3 weeks. Resolution of mucositis correlates with recovery of white blood cells, specifically the neutrophils. A patient may safely receive dental treatment when blood counts have begun to recover, usually just before the next round of chemotherapy. Dental care during cancer treatment is based on neutrophil and platelet counts. The absolute minimum blood counts for safe dental care are 1,000mm3 neutrophils and 50,000mm3 platelets.

Management of oral mucositis Thorough bacterial plaque control and consistent hydration can help minimize the severity of mucositis. Recommendations include the following: • Brush three times daily: –Extra soft toothbrush • • • • May delay wound healing • Causes demineralization • May promote emesis • Causes dry mouth, thirst, and discomfort • Promotes fungal growth • Unpleasant taste • Increased stinging /burning • Unpleasant taste • Drowsiness –Sponge brush dipped in chlorhexidine is effective in reducing plaque and oral microorganisms. Due to alcohol content, burning may be a problem. Use 1.1% neutral sodium fluoride toothpaste. Floss with a waxed or coated floss to prevent damage to the soft tissues. Supervision of floss technique is important, especially during periods of myelosuppression. Rinse with water or a simple saline solution (1/2 tsp. salt in 8 oz. water) while brushing and between meals. 6www.ineedce.com • • Over the counter mouthrinses are not recommended due to alcohol content. (See Table 4 for additional mouthrinse information.) Instruct patients not to wear dental prostheses while receiving chemotherapy. If they must, they should limit their use and they should not be worn during times of significant oral soreness. –Prostheses should be cleaned twice daily with a soft brush, rinsed well and soaked in an antimicrobial solution for 30 minutes after cleaning. –Patients should use sodium hypochlorite diluted 1:25 with water or chlorhexidine for soaking. Chapped lips are a common complication of cancer chemotherapy. The use of lanolin cream or ointment can provide better lip protection and soothing of cracked and split lips than a petroleum based product. Management of mucositis induced pain It is estimated that 45% - 80% of all cancer patients have inadequate pain management. Pain may be present in up to 85% of patients with head and neck cancers at diagnosis. Orofacial pain associated with cancer therapy is a well recognized adverse effect of treatment and pain due to oral mucositis is the most frequently reported complaint during cancer therapy.17 The impact of mucositis pain is profound because it can interfere with therapy by necessitating treatment delays and dose reductions that can interfere with cancer cures; increase cost of care; interfere with oral function, making it difficult or impossible to eat, drink or swallow; affect mood or behavior and dramatically diminish the quality of life. Mucosal pain may persist long after the mucositis resolves, suggesting that chronic symptoms may be related to tissue changes, including epithelial atrophy and/or neuropathy.18 Topical anesthetics have a limited duration, may sting on application to damaged mucosa, and may affect taste. The flavor of topical anesthetics may cause gagging or emesis. One of the most frequently prescribed treatments for mucositis pain is “magic mouthwash.” These rinses are combinations of anesthetics with an antacid coating agent, an antifungal agent, and sometimes a steroid. A compounded rinse may provide palliative pain control due to the anesthetic but there is no evidence that they are more effective than the topical agents used alone. Many commercial products are marketed for oral mucositis pain but have not been proven clinically effective. These include mucosal covering agents. Film forming agents provide a thick adherent barrier over ulcerated mucosa and may reduce pain. Systemic medications used for mucositis include opioids and non-steroidal anti-inflammatory medications (NSAIDS). Opioids have been shown to be very effective www.ineedce.com Table 5: Topical anesthetics for mucositis pain management 20 Agent Formulations True Topical Anesthetics Lidocaine Viscous gel, jelly, ointment, solution, patches Benzocaine Gel, ointment, spray Tetracaine/Chirocaine Anesthetic tabs EMLA Cream “Magic Mouth Rinse” Compounded rinse (Lidocaine, diphenhydramine, Amphogel ± Nystatin) Antihistamines Diphenhydramine Elixir, IV solution Other agents Doxepin Elixir Benzydamine Rinse (not available in US) Benzonatate Gel caps (open and coat mouth) Cocaine Compound 10% solution Table 6: Non-steroidal anti-inflammatory 21 Drug Common Name Paracetaol Acetaminophen Propionic acids Ibuprophen, Naproxen, Naproxen Sodium, Fenoprophen, Ketoprophen, Flurbiprophen, Oxaprozin Meclofenamic acid Meclomen Acetic acids Diclofenac potassium, ,Sulinda, Ketorolac, Etodolac Nonselective COX-1 and COX-2 inhibitors Aspirin, Diflunisal, Choline magnesium trisalicylate Selective COX-2 inhibitors Celecoxib (see FDA alert) Cox/Lox inhibitor Lilofelone (under development) Oxicams Piroxicam, Tenoxicam, Droxicam, Lomoxicam, Meloxicam Table 7: Opioid medications for mild to moderate mucositis pain 22 Drug Dosage Codeine phosphate* 15 mg – 60 mg PO/SC/IM q4-6h Codeine sulphate* 15 mg – 60 mg PO q4-6h Oxycodone* 15 mg – 30 mg PO q4h Oxycodone extended release tabs* 10 mg – 160 mg PO q12h Hydrocodone* 5 mg – 10 mg PO q4-6h * Combined with acetaminophen, aspirin, or Ibuprophen, which can be dose limiting 7 Table 8: Opioid medications for moderate to severe mucositis pain Drug Dosage Morphine Oral 10 mg – 60 mg PO Morphine extended release 15 mg – 30 mg PO q8-12h Morphine IV, IM Varies Hydromorphone 2 mg – 8 mg PO q3-4h; 1 mg - 4 mg SC/IM/IV Oxycodone* 15 mg – 30 mg PO q4h Oxycodone extended release* 10 mg – 160 mg PO q12h Oxymorphone* 10 mg – 20 mg PO q4h Oxymorphone extended release* 5 mg – 40 mg PO q12h Oxymorphone* 1 mg – 1.5 mg SC/2.5-5mg SC/ IM/IV q8-12h Methadone 2.5 mg – 10 mg PO b.i.d. or t.i.d./10 mg IM Levorphanol 2mg PO q6-8h Fentanyl transdermal patch 12 mg – 1,000 mcg/h patch q72h Fentanyl Intravenous 50 mg – 100 mcg/kg IV q1-2h Fentanyl transmucosal** 100 mg – 200 mcg per dose (titrate q15 min. p.r.n.)

There are two categories of opioid medications: those used for mild to moderate pain and those used for moderate to severe pain. Continuous time based dosing is more effective than pain contingent dosing. Extended release formulations are the most popular.19 The use of NSAIDS is contraindicated where concerns for bleeding due to low platelet counts are present. Adjuvant medications and therapies may be beneficial in controlling mucositis pain. These include muscle relaxants, anti-inflammatories, antianxiety medications, antidepressants, anticonvulsants, relaxation, meditation, transcutaneous nerve stimulation, cold/moist heat applications, ice chips, hypnosis, acupuncture and counseling. A modified diet consisting of soft and moist foods is beneficial. Xerostomia (salivary gland dysfunction/ dry mouth) Radiation of the salivary glands results in atrophy of the secretory cells and subsequent dry mouth or xerostomia. The degree of xerostomia is related to the dose of radiation and the amount of salivary gland tissue in the radiation field. Although Intensity-Modulated Radiation Therapy (IMRT) has reduced the severity of xerostomia, it still occurs to some degree in most patients.23 Radiation doses as low as 25 Gy can result in hypofunction of salivary glands and permanent xerostomia results at doses greater than 35-52 Gy. Serous glands degenerate faster than mucous glands, resulting in thicker and more acidic saliva. Multiple abnormalities can occur following degeneration of salivary glands, including impaired antimicrobial capacity and mouth cleansing, taste alterations, and difficulties in oral functions such as chewing, swallowing and speaking.24 Loss of salivary function also leads to esophageal dysfunction, including chronic esophagitis, nutritional compromise, higher frequency of intolerance to oral medications, increased infections, loss of buffering capacity, reduction in remineralizing capacity leading to dental sensitivity and increased susceptibility to dental caries, increased loss of tooth structure due to attrition, abrasion, and erosion and increased susceptibility to mucosal injury. Xerostomia also results in difficulty sleeping due to oral dryness. It can contribute to emotional challenges such as social withdrawal and depression. Management of xerostomia Managing the oral health of a patient with radiation induced xerostomia is enormously challenging. It requires a lifelong commitment to impeccable oral care. It is imperative to educate the patient regarding the potentially devastating effects of radiation on the dentition and the mucous membranes. Topical management of xerostomia Unfiltered fluoride containing tap water is the most recommended mouth moisturizer because it is inexpensive and it delivers some fluoride to help protect the teeth with each sip. Bottled water doesn’t contain fluoride and should be discouraged. The moisturizing effect of water is short lived. Patients are encouraged to carry water with them at all times and sip frequently throughout the day and night. Commercially available salivary substitutes can also be used to moisten the mouth. It is preferable to use one with a pH over 5.1 to prevent demineralization of tooth enamel. Most commercial salivary substitutes are expensive and have a short duration of action. Some saliva substitutes are formulated as viscous gels or are made with a silicone molecule that has an affinity for mucosa. These products can be used to coat the oral soft tissues to protect and lubricate them for a longer duration. They may be beneficial at bedtime. Over the counter sugar free gums and mints are safe to use to stimulate any remaining salivary function; however, xylitol containing items are preferable because xylitol inhibits the growth of cariogenic bacteria (mutans 8www.ineedce.com streptococci).25 For those patients with no residual salivary function, these items will not be tolerated well as they tend to stick to the tissues and can even irritate or tear the fragile, dry mucosa. Systemic management of xerostomia A systemic sialagogue can be prescribed to stimulate salivary flow in a patient who has reduced salivary flow. Sialagogues are available as tablets, capsules, and an ophthalmic solution that can be placed under the tongue. If there is no residual salivary function, a sialagogue will be ineffective.26 Prevention of xerostomia induced dental caries The following requirements must be followed to maintain the patient’s dentition: • Avoid moistening the mouth with cariogenic liquids such as sodas, citrus flavored or carbonated water, juices, teas, or any other liquid containing sugar. • Avoid using any liquid with an acidic pH to moisten the mouth. • Avoid using foods with sugar to stimulate salivary flow such as gums, mints, candies, lemon drops, etc. • Brush teeth after every meal or snack. • Perform thorough oral hygiene procedures at least twice a day with a soft toothbrush and fluoride toothpaste that contains 1,100 ppm – 5,000 ppm fluoride ion. • Avoid 0.05% sodium fluoride rinses and 0.63% stannous fluoride rinses for head and neck cancer patients because low concentration products have not been shown to be effective in xerostomic patients. • Use a 1.1% topical fluoride gel daily in custom trays 1. The optimal time to use fluoride trays is immediately before bedtime. 2. Insert both upper and lower trays and bite gently a few times to “pump” gel between the teeth. 3. Leave the fluoride trays in the mouth for 5-10 minutes. 4. Remove and expectorate the gel several times but do not rinse. 5. Rinse the trays and allow to air dry. 6. Do not eat or brush teeth for at least 30 minutes. • Initiate antimicrobial therapy using a 0.12% chlorhexidine rinse. The normal recommendation is to use ½ oz. for one minute twice daily for two weeks. This will reduce the number of mutans streptococci below the pathological level for 12-36 weeks for non-cancer patients. For head and neck cancer patients, however, rapid recolonization occurs when chlorhexidine is discontinued. Continuing use of chlorhexidine rinses is recommended.27 • Use fluoride varnish to protect the teeth against demineralization and promote remineralization. www.ineedce.com Table 9: Management and medications for HSV infections associated with mucositis 33,34 Management Culture all lip, palate, and tongue lesions in HSV-antibody positive patients unless patient is already taking acyclovir. Medication Serological results are not helpful in confirming the diagnosis of HSV-1 during immunosuppression. Topical ointments are not appropriate, as extent of disease requires systemic therapy. IV route of medication is preferred in cases where chemotherapy-induced or radiation-induced Mucositis impedes oral intake. Outpatient treatment for less severe outbreak. • Rx: Acyclovir 400 mg capsules • Disp: 21 capsules • Sig: Take one capsule three times per day for seven days Inpatient treatment for more severe disease. • Rx: Acyclovir IV • Sig: 5mg/kg every eight hours for seven days Options with better compliance but higher cost. • Rx: Famciclovir or Valacyclovir 500 mg. capsules • Disp: 14 capsules • Sig: Take one capsule two times per day for seven days Option for acyclovir-resistant viruses. • Rx: Foscarnet • Sig: 60 mg/kg IV every 12 hours or 40 mg/kg every 8 hours for 7 days – 21 days or until complete healing • • Use products that contain calcium and phosphate as studies show their presence is required in order to reduce demineralization and promote remineralization. Commit to professional dental examination every three months the first year and at three to six month intervals thereafter depending on the oral condition. Candidiasis In patients with head and neck cancer who have received radiation therapy and have resulting xerostomia, the oral tissues become dry, rough, sticky, and more susceptible to infection. The most common infection found in patients with hypo-salivation is candidiasis. Candidiasis may present as a pseudomembranous form (thrush), as an atrophic (erythematous) form, often associated with removable dental appliances or less commonly, as a hypertrophic (white) form. Candidiasis should be suspected when xerostomic patients complain of a burning mouth or tongue. This infection may spread to involve the commissures of the mouth, which is described as angular cheilitis or cheilosis. 9 Management of candidiasis Several antifungal agents are effective against candida albicans. Nystatin solutions are high in sucrose and should be avoided in dentate dry mouth patients. Antifungal agents often come in the form of troches or pastilles but neither is tolerated well by patients with hyposalivation because they lack sufficient saliva to dissolve them and because they may cause mucosal abrasion. Topical creams, lozenges or rinses are preferable. Systemic antifungal agents are effective and do not require dosing as often as topical agents, which is important because compliance can be a significant problem for patients with fungal infections. possibility of interfering with or termination of the planned chemotherapy regimen. Taste alterations caused by chemotherapy usually resolve in three to four weeks following treatment. Dysgeusia resulting from radiation to the head and neck may begin to improve in three to eight weeks following radiation treatment and improvement may continue slowly over the course of a year. If the radiation resulted in damaged salivary glands, taste sensation may never recover. Taste alterations and nutritional deficiencies Management of taste alterations and nutritional deficiencies • Keep mouth clean and healthy as much as possible as a clean mouth may improve taste in some people. • Ask the oncologist about zinc sulfate supplements, which may improve taste in some people. • Rinse with salt and baking soda solution (½ tsp. salt and ½ tsp. baking soda in 1 cup warm water) before meals. May help neutralize bad tastes in the mouth. • Do not eat one to two hours before chemotherapy and up to three hours following chemotherapy to prevent food aversions caused by nausea and vomiting. • Choose foods that smell and taste good, whenever possible, even if the food is unfamiliar. • Marinate meats in fruit juices, sweet wines, salad dressings, or other sauces. This helps with xerostomia as well*. • Flavor foods with spices, herbs, citrus fruits, sugar, and other sauces*. • Eat a variety of protein sources such as poultry, eggs, fish, peanut or other nut butters, beans and dairy products in addition to red meats. • Use protein drinks to supplement diet when taste aversions limit nutritional intake. Various flavorings may be added to these drinks. • Try sugar free gum, mints and other hard candies to mask a metallic or bitter taste. Use products with xylitol to prevent tooth decay. * It is imperative to advise patients that if they use sauces and other flavorings and marinades with sugar, they must be impeccable with their home care techniques, including the twice daily use of 5,000ppm neutral sodium fluoride toothpaste and daily use of 1.1% neutral sodium fluoride gel in custom trays. The risk for dental caries is high and must be considered when choosing ways to make foods more palatable and easier to swallow. Taste alteration (dysgeusia) is a common side effect of cancer chemotherapy.36 Food may taste differently than before therapy or may have no taste at all. Commonly, patients complain of a metallic or chemical taste, all food tasting the same or food tasting like cardboard. Dysgeusia may reduce the patient’s appetite, leading to poor oral intake, poor nutrition, poor hydration and the Osteoradionecrosis Osteoradionecrosis (ORN) is a rare late effect that occurs after radiation therapy has been completed. ORN is the most serious potential complication for the head and neck cancer patient.37 ORN is irreversible, progressive devitalization of irradiated bone. This condition causes necrotic Viral infections Herpes simplex virus type 1 (HSV-1) reactivation happens most commonly in conjunction with chemotherapy induced mucositis. Since patients receiving chemotherapy are expected to develop mucositis, the caregiver may overlook HSV-1 reactivation as an etiologic factor in the oral ulcerations. Mucositis complicated by HSV-1 reactivation is more severe and longer lasting and has serious local implications. The ulcerations may appear in multiple locations involving any intraoral and perioral soft tissue surfaces. HSV-1 reactivation can cause severe pain and impaired nutrition and hydration. The systemic consequence of HSV-1 reactivation is the disruption of the mucosal barrier, creating a site of entry for oral microorganisms, which can lead to sepsis. In leukemia and bone marrow transplant patients, prophylactic acyclovir is effective in controlling HSV reactivation and is used commonly in bone marrow transplant patients. It is not used routinely for patients undergoing chemotherapy. Those patients should be monitored for HSV-1 reactivation and treated quickly with acyclovir if HSV-1 reactivation is suspected. Other viral infections are problematic during cancer chemotherapy, including herpes varicella zoster virus (VZV), cytomegalovirus (CMV), Epstein-Barr virus (EBV), human herpes viruses (HHV-6, 7, 8) and respiratory viruses. Management of viral infections Table 9 contains detailed information on the management and medication of viral infections. 10www.ineedce.com soft tissue and bone that fails to heal following surgery or injury. Most cases of ORN occur in the mandible where vascularization is poor and bone density is high. Very rarely, ORN can start in the maxilla.38 Because radiation destroys cancer cells through the deprivation of oxygen and vital nutrients, it inevitably destroys normal cells as well, damaging blood vessels and reducing circulation to the area of the bone. Insufficient blood supply to the irradiated areas decreases the ability to heal. Any subsequent infections or injury to the bone can pose a major risk to the patient. ORN happens most often following an insult to the bone in the irradiated area such as; surgery, biopsy, tooth extractions or irritation from dental appliances.39 Clinically, ORN may manifest as pain, swelling, reduced mobility of the jaw (trismus), orofacial fistulas, exposed necrotic bone (sequestrum), fracture and suppuration (exudate). Many factors can contribute to the development of ORN. Any patient receiving more than 40 Gy radiation is at risk for ORN, but it occurs more often at doses over 60 Gy. Many head and neck cancer patients receive more than 70 Gy radiation therapies. There is increased risk associated with a combination of radiation and chemotherapy. The location and size of the tumor are also contributing factors. The immunologic and nutritional health of the patient at the time of treatment and smoking at the time of treatment all factor into the risk for ORN.40 Treatment of osteoradionecrosis of the bone is difficult; therefore, prevention of ORN should be the focus of the pretreatment assessment. Most cases of ORN respond to conservative treatment for pain control and long term oral antibiotic therapy.41 In cases that do not respond well to antibiotic therapy, local debridement of the infected bone is an option. Hyperbaric oxygen therapy (HBO) has proven to be effective by increasing tissue oxygen levels.42 Other adjunctive therapies to manage ORN such as; ozone therapy, laser therapy, tetracycline-guided debridement and parathyroid hormone supplementation have been proposed. Further study is necessary to develop specific recommendations. Conclusion The best treatment for the side effects of cancer treatment is prevention. The pre-cancer treatment assessment and dental care appointment are crucial in the prevention of possible negative oral sequelae of cancer care. The negative consequences that occur despite the best efforts of the cancer care team can range from mild to severe, acute to chronic. They can affect the patient physically as well as emotionally and they can interrupt and even stop the course of cancer treatment. Negative side effects can affect the quality of the patient’s life and put that life at greater risk. Customized treatment plans must be developed to address the various side effects the patient is experiencwww.ineedce.com ing and coordination with the oncology team is critical in managing these negative oral consequences. The overview presented in this course will make the practitioner aware of the variety of negative consequences that can occur as a result of cancer treatment and the recommended management strategies available to care for these patients during times of pain and suffering.
