Head and Neck Cancer Statistics • Cancers of the H&N: oral cavity/larynx/pharynx/salivary glands/nose • Standard tx include: RT, CT, a combo CRT, and surgery • • • • H&N Ca account for approx. 3% of all malignancies in US 5th most common Ca in US 50,000 new H&N Ca cases per year in US 20,000 deaths per year in US • Overall incidence began decreasing 30 years ago, stabilized in 2003 • Whereas overall mortality rates have steadily declined Head and Neck Ca Risk Factors • • • • Old Guard: Tobacco intake alone = increases risk Alcohol intake alone = mildly increases risk Tobacco and alcohol intake together = significant increased risk • New Guard: • Human papillomavirus (HPV P16+) > ½ of all oropharyngeal Ca cases • 225% increase in HPV P16+ oral pharyngeal Ca • HPV is sexually transmitted w increasing risk of: • # of sexual partners • First intercourse < or = 17 y/o • Reduced use of condoms Tumor Sites • A majority of H&N Ca tumors arise from squamous mucosa that lines the upper aerodigestive track and are predominantly squamous cell carcinomas. • Upper aerodigestive track anatomic subsites include: Oral cavity Tumor Sites Oropharynx Tumor Sites Hypopharynx Tumor Sites Larynx Tumor Sites Nasopharynx Tumor Sites Nose and Paranasal Sinuses Head and Neck Lymph Node System Head and Neck Lymph Node System Tumor Sites: Oral Cavity • Oral Cavity Sub-sites: lips, anterior tongue, floor of mouth, buccal mucosa, upper/lower alveolar ridges, hard palate and retromolar trigone • Lymph node spread: to lymph nodes of submandibular region and upper/middle jugular chain lymph nodes • Treatment: mandible and maxilla bone structures preclude using RT due to radionecrosis, primary tx is surgical • Positive surgical margins, and/or multiple lymph node involvement may call for postoperative CRT to improve local disease control. Take Home Message: Oral Cavity Ca= surgery w CRT only if unable to resect whole tumor • Tumor Sites: Oropharynx • Oropharynx Sub-sites: tonsil, base of tongue, soft palate, pharyngeal walls • Lymph node spread: metastasize to upper/middle jugular chain lymph nodes, but may also spread to retropharyngeal lymph nodes • • • • Treatment: complex depending on how advanced the disease is RT alone and/or CRT may be utilized NOTE: Some of these cancers are associated with HPV P16 +. Increased incidence of HPV 16+ in 30-50 y/o men, vaccine Gardisol. Tumor Sites: Hypopharynx • Hypopharynx Sub-sites: pyriform sinuses, post cricoid region, pharyngeal walls • • • Lymph node spread: metastasize to upper, middle, and lower jugular lymph nodes and retropharyngeal nodes often advanced and difficult to cure location can impact swallowing/speech • Treatment: surgery, CRT Tumor Sites: Larynx • Larynx Sub-sites: supraglottic, glottis, and subglottic areas • Lymph node spread: metastasize to the upper, middle, and lower jugular chain lymph nodes • • • • Treatment: tx for laryngeal cancers variesEarly stage lesions RT or transoral endoscopic excision are common Later stage lesions laryngectomy was standard for T3 and T4 larynx Ca.

These problems led to developing one SPP for whole Sharp Healthcare system. • Question • This is the question we asked ourselves: • In the outpatient H&N CA population, is a standardized swallowing preservation protocol more effective in maintaining per oral intake and QOL outcomes than the current traditional process of evaluating and treating swallowing dysfunction after the pt experiences CRT? Creating A Swallow Preservation Protocol (SPP) • Where did we start? Description of Initiative • • • • • • • • Review of the literature Assessed traditional practice Retrospective data analysis Development of SPP Analysis of SPP pt data Presented information to sources Educated SLPs on SPP Created a competency Healthcare Professionals Involved: • Referring MD: primary MD, oncologist, ENT, Otolaryngologist, dentist • Radiologist: scans tumor (MRI, CT, PET, needle biopsy) Pt then referred to 1,2, or all of 3 MDs depending on TNM tumor staging, placement. • • • Radiation Oncologist: administers radiation Chemotherapy Oncologist: administers systemic chemotherapy Surgeon: excises tumor Healthcare Professionals Involved: • Other Related Professionals: • • Dentist: RT= referral for check up- dental work required prior to RT tooth extraction, deep cleaning, dental trays • GI Doc: PEG tube placement prior to CRT • Cancer Patient Navigator: coordinates pt care • • R.D. Board Certified Specialist in Oncology Nutrition: caloric intake via p.o./PEG tube • SLP: speech-language/swallow deficits/counseling • Palliative Care/Hospice Care MD/NSG: for end of life issues Tumor Rounds/Tumor Board: • • • • Participate in tumor rounds/board w Radiologists, Radiation/chemotherapy Oncologists, General Surgeons, Plastic Surgeons, and histopathologists Also attending: RD, Geneticists, Palliative/Hospice MDs/NSGs, Cancer Patient Navigator Role: report on pt’s tx/progress, evals completed (FEES, MBS, strobes) request consults/referrals for new pts Head and Neck Ca Screening Tool Head and Neck Ca Screening Tool • No standard/routine screening tests for H&N Ca • Studies show survival rates reduced secondary to Ca progression when first diagnosed. • Early detection = decreased mortality for H&N Ca pts • • • Problem: Most pts diagnosed at advanced stages when < 50% are curable Therefore, SLP completing screening appears appropriate. Head and Neck Ca Screening Tool When to screen: during OME Teach SLPs to recognize: s/s of H&N CA and refer • Swelling or sore that does not heal • Red or white patch in mouth • Lump/bump/mass in head/neck, w/w-out pain • Persistent sore throat • Foul mouth odor not explained by hygiene (halitosis) • Hoarseness /change in vocal quality • Nasal obstruction/persistent nasal congestion • Frequent nose bleeds /unusual discharge • Difficulty breathing • Double vision/hearing loss • Numbness/weakness of a body part in head/neck region • Odynophagia/difficulty w swallowing/change in diet • Blood in saliva/phlegm • Loosening of teeth/ tooth aches • Dentures that no longer fit • Unexplained weight loss • Fatigue Head and Neck Ca Screening Tool Overview • www.sixstepscreening.org/dentist-rdh/video-head-neck-exam/ • Detailed video of an intra/extra oral exam/six step screening • Neck Screening: Palpate neck for tenderness, new lumps on both sides with fingers. Head and Neck Ca Screening Tool Overview • Lips Screening: Palpate upper/lower lip inside and out looking for skin discoloration/changes, use thumb and index finger. Head and Neck Ca Screening Tool Overview • Buccal Cavity Screening: Visually assess cheeks looking in oral cavity for skin discoloration/changes/sores that have not healed. • Use fingers feeling for new lumps in both cheeks. Head and Neck Ca Screening Tool Overview • Lingual Screening: Visually assess tongue for discoloration/changes/sores, use finger feeling for new lumps. • Use 4x4 gauze to hold tongue left and right. Head and Neck Ca Screening Tool • Teeth/Gums Screening: Visually assess teeth, gums for discoloration/changes/sores, use fingers to feel for new lumps on lips and gums. Head and Neck Ca Screening Tool Hard Palate/Velum Screening: Visually assess hard and soft palate for discoloration/changes/sores. Have pt say “ah”. Head and Neck Ca Screening Tool • As SLP use screening only to assess risk - then refer. • SLPs do not diagnose - only refer. • • • • Screening results: Send report/telephone screening results to MD. Advise pt to follow-up with MD. SLP follows up with MD. Head and Neck Ca Screening Tool Dental hygienists use Toluidine Blue(metachromatic dye) to detect mucosal abnormalities • Four chemiluminescence diagnostic aids: • Vizilite System Plus with Toluidine Blue • Velscope (visually enhanced lesion) System • MicroLUX DL System • Orascoptic DK System **questionable if theses systems aid in detection and better outcomes. • Creating Swallow Preservation Protocol • Changing the culture of referral method is the first step. Swallow Preservation Protocol (SPP) • Original Referral Method: Obtain script from rad oncologist when pt shows overt s/s of dysphagia during/post CRT. • SPP Referral Method: Obtain script from rad/chemo oncologist prior to CRT. • Pts to consider for ed./tx: Pt with upcoming RT/CT/CRT or surgery. • Pre-RT Consult: Pre-RT SPP ed. prevents/lessens negative changes in swallowing.

Head And Neck Stretching Exercises • Head Forward/Backward: • This exercise is great for stretching out your neck and getting loose. Stand or sit with your feet about shoulder width apart and simply nod your head forward and down as far as possible. From there, rock your head up and back as far as possible. Head And Neck Stretching Exercises • Head Circular Motion: • This exercise is great for stretching out your neck and getting loose. Stand or sit with your feet about shoulder width apart and simply roll your head around in a large circular motion. Do this for 5 repetitions then reverse directions and repeat in the opposite direction. Head And Neck Stretching Exercises • Head Side to Side: • This exercise is great for stretching out your neck and getting loose. Stand or sit with your feet about shoulder width apart and simply move your head from side to side so as to try and touch your left ear to your left shoulder and your right ear to your right shoulder. Head And Neck Stretching Exercises • Head Turn: • This exercise is great for stretching out your neck and getting loose. Stand or sit with your feet about shoulder width apart and simply turn your head from side to side as far as you can each way. Head And Neck Stretching Exercises • • • Isometric Neck Exercises: FRONT and BACK For the front exercise, place your hands flat on your forehead. Next, firmly push your forehead forward against your hands. The key to this exercise is to not allow your forehead to move forward so as to create and maintain constant tension on your neck muscles. Continue pushing forward for a 10 second count and then relax. Now switch to the back or rear part of this exercise. For the rear exercise, begin by clasping your hands behind your head. Next, firmly push the back of your head against your hands. The key to this exercise is to not allow your forehead to move backward so as to create and maintain constant tension on your neck muscles. Continue pushing backwards for a 10 second count and then relax. Now alternate front and back parts of this exercise. Head And Neck Stretching Exercises • Isometric neck exercises: SIDES Place your right hand flat on the side of your head. Next, firmly push your head against your right hand. The key to this exercise is not to allow your head to move so as to create and maintain constant tension on your neck muscles. Continue pushing against your right hand for a 10 second count and then switch to the left side and repeat the exercise. • Taken from: www.shapefit.com Pre- Ed.

Taste cells are also cells which grow rapidly. This means that chemotherapy drugs end up targeting the taste cells along with the cancer cells. When chemotherapy medications are injected into the bloodstream, they also get into saliva, and most medications have a very bitter taste, causing a bitter taste in your mouth. Chemotherapy can also cause foods to not taste the same, for example, foods may often seem too sweet, too salty, too bitter or without taste at all. Suggestions to Help Enjoy Foods During Chemotherapy: Introduce new spices like cumin, cinnamon, and coriander. If water or food tastes like metal add a little acid such as lemons, limes, or oranges. If foods taste bitter or harsh add a very small drop of Grade B organic maple syrup. Add good fats to your cooking, as fat is a natural flavor carrier, such as olive oil, coconut oil, nuts and seeds. Holding On To Your Favorite Foods: Many patients discover that the food eaten during chemotherapy is nearly impossible to consume after treatment is over due to strong memories and associations of bad tastes of those foods . Therefore, you may want to avoid eating your favorite foods during chemotherapy so that when treatment is over, you can still enjoy the food you once loved. Two Chemotherapy Cook Books: The Cancer-Fighting Kitchen by Rebecca Katz One Bite At A Time by Rebecca Katz Lastly, prior to making any changes with your diet during chemotherapy, please consult your physician and dietitian. Pre- Ed. Swallow Preservation Protocol • • • • • • • • • • Discuss: Reduce intake of drying agents during/post RT - caffeine-coffee-chocolate-tea mint-peppermints-menthol Oral hygiene- brush 3 times daily-reduce bacteria buildup-directly linked to aspiration PNA Dental trays throughout RT (SLP reinforces use) Increasing dental cleanings to 3-4 times per year post RT (decreased saliva production = damage to dentition over time) Voice changes (e.g. harsh, hoarse, breathy voice during/post RT) options for tx Late effects of RT 7-12 years tissue fibrosis, late effects change swallowing Above structural/functional changes are rare, are only possible effects of RT Pre- Ed. Swallow Preservation Protocol B) Aspiration Risk During /Post RT: Define Aspiration PNA: • Aspiration pneumonia is often caused by an incompetent swallowing mechanism, such as occurs in some forms of neurological disease (a common cause being strokes) or when there is structural or physiological changes post radiation therapy impeding the swallowing mechanism. Generally the right middle and lower lung lobes are most common sites of infiltrate formation due to the larger caliber and more vertical orientation of the right mainstem bronchus. Patients who aspirate while standing can have bilateral lower lung lobe infiltrates. • Aspiration pneumonia is typically diagnosed by a combination of clinical circumstances (debilitated or neurologically impaired patient), radiologic findings (right lower lobe pneumonia) and microbiologic cultures. Some cases of aspiration pneumonia are caused by aspiration of food particles or other particulate substances like pill fragments; these can be diagnosed by pathologists on lung biopsy specimens.

Therefore a RSI > 13 may be indicative of significant reflux disease. Swallow Preservation Protocol Laryngeal Pharyngeal Reflux/Gastro Esophageal Reflux Handout Definition of Laryngopharyngeal Reflux or LPR: • LPR is when stomach acid refluxes into the voice box and throat which may or may not cause the patient heartburn or indigestion. Symptoms of LPR/GER: • Patient may experience coughing, throat clearing, sore throat, voice changes, difficulty swallowing, feeling of food sticking in throat, or acidic taste in mouth. Treatment For LPR/GER: • Treatment may include a pairing of both medication and changes in diet and lifestyle. Severe cases of LPR/GER that are persistent may require Fundoplication (Nissen Fundoplication) surgery. The procedure essentially tightens the lower esophageal sphincter around the lower portion of the esophagus to reduce backflow of stomach acids into the esophagus. Dietary Restrictions: Food Changes: • Bland diet • Reduce high acid content foods such as spicy foods, tomato-based foods. • Reduce food with mint or menthol. • Reduce breath mints, throat lozenges. • Reduce or avoid altogether fatty foods, caffeine, sugary foods, chocolate, onions. Beverage Changes: • Reduce caffeine intake. • Reduce citrus fruits or fruit juice intake. • Reduce alcohol intake. • Reduce carbonated drinks such as soft drinks, sodas. Lifestyle Changes: • Elevate head of bed four to eight inches with books or blocks or use wedge pillows (do not use soft pillows as it will constrict your stomach). This will help keep stomach acid from flowing into your esophagus when you are sleeping. • Avoid eating one to three hours prior to bedtime. • Stay upright at 90 degrees for 60-90 minutes post meals. • Avoid overeating. • Avoid heavy meals that promote large amounts of acid production. • Avoid or reduce pressure on your stomach, avoid tight constrictive clothing including belts, etc. • Lose weight if you are overweight. Being overweight puts additional pressure on your stomach and increases the likelihood of LPR/GER occurring. Even losing a few pounds can help. • Stop smoking. • Reduce stress. • Incorporate an exercise program regularly.

SPP Post Test Example Questions What does SPP stand for? • • • Swallow Preservation Protocol Swallowing Per Person Swallowing Preserved Practicum The Functional Oral Intake Scale measures? • Reliability in swallowing • Amount and consistency of oral intake • Amount of tube feeding The EAT-10 measures? • How many meals eaten in a week • Pounds of food eaten per meal • Ounces of liquid intake per meal • Quality of life A standardized swallow treatment plan entails? • Periodic f/u during and throughout CRT/recovery • Periodic assessments/regimented exercises • All of the above Does the swallow preservation protocol reduce? • Rate of dysphagia • Aspiration risk/rate secondary to aspiration PNA • Hospital admissions secondary to dehydration/aspiration PNA • Time/needed for alternate nutrition (PEG tube) • All of the above Internal Study: The Impact of a SPP on Pts with H&N Ca Internal Study: The Impact of a SPP on Pts with H&N Ca • • Methods: This project is a pre-post interventional design. • Patients with H&N CA completed a pre-post functional oral intake scale (FOIS) and QOL index (EAT-10). • Oral intake and QOL outcome measures for the SPP group were compared to traditional swallow therapy group using mixed Analysis of Variance (ANOVA). Participants • Three licensed SLPs from Sharp Grossmont Hospital, Sharp Chula Vista Medical Center, and Sharp Memorial Hospital 16 SPP patients: • Performed standardized exercises throughout CRT • Periodic f/u during treatment and through recovery 16 traditional swallow treatment patients: • Assessed retrospective data analysis from 2012-2014 • Performed non-standardized exercises post onset of dysphagia Outcomes Functional Oral Intake Scale (FOIS) 6.1 7 6 5 3.4 4 3.5 2.9 3 2 1 0 Initial SPP DC SPP Initial Traditional DC Traditional • SPP: FOIS mean scores increased by 3.2, F(1,30)=29.83, p<.0001 • Traditional: FOIS scores increased by only 0.1, F<1 Interpretation: • SPP: increased from tube supplements with consistent oral intake to total oral intake with avoiding specific food/liquids only • Traditional: no significant change Outcomes Continued EAT-10 Quality of Life Scale 40 35 30 24.4 22.7 24.7 25 20 15 6.2 10 5 0 Initial SPP DC SPP Initial Traditional DC Traditional SPP: EAT-10 mean scores decreased by 16.5, F(1,24)=44.91, p<.0001 Traditional: EAT-10 scores increased by 0.3, F<1, lower scores = improved perceived swallowing function Interpretation: • SPP: reported statistically significant perceived improvement in swallowing comfort/ease and QOL • Traditional: reported no significant change • • Conclusion • • • • SPP made statically significant improvement in swallow function and QOL post treatment. SPP increased from tube supplements with consistent oral intake to total oral intake with avoiding specific food/liquids only. SPP reported perceived improvement in ease of swallowing and QOL. Traditional reported no significant change in functional eating and QOL. Implications Direct Outcomes: • Standardization of swallow treatment for patients with H&N Ca across all Sharp Healthcare entities • Preservation of swallow function during/post CRT • Enhanced QOL during/post CRT • Empowerment for patients in healing process during/post treatment • Enhanced oncology team List benefits to MDs • Less chance of pts requiring alternate feeding (PEG tube) for long periods of time post CRT. • Maintain weight - good nutrition throughout CRT via p.o. /PEG • Pt feels like she is actively participating in own outcome of tx. • Reduced cost with reduced re-hospitalizations for aspiration PNA/dehydration. • Pt feels more informed - outcomes are better- pt happier with overall experience. Where Do We Go From Here? • Continue to forge relationships with MDs to ensure pre CRT/surgery referrals • Ed. incoming SLPs/new hires • Complete yearly competency for all SLPs • Continue to stay current with H&N Ca literature • Integrate new literature findings into protocol • Continue to gather data and monitor strength of SPP with pts Thoughts?
