Evaluation of a speech pathology service delivery model for patients at low dysphagia risk during radiotherapy for HNC.

PURPOSE: There are no evidence-based guidelines informing which patients with head and neck cancer (HNC) require regular speech pathology (SP) support during radiation treatment (RT). Hence, some services use a "one-size-fits-all" model, potentially over-servicing those patients at low risk for dysphagia. This study evaluated the clinical safety and efficiency of an interdisciplinary service model for patients identified prospectively as "low risk" for dysphagia during RT. METHODS: A prospective cohort of 65 patients with HNCs of the skin, thyroid, parotid, nose, and salivary glands, receiving curative RT, were managed on a low-risk pathway. Patients with baseline dysphagia (functional oral intake score ≤ 5) were excluded. The model involved dietitians conducting dysphagia screening at weeks 3, 5, and 6/7 within scheduled appointments. Patients at risk of dysphagia were referred to SP for assessment, then management if required. To validate the model, SP assessed swallow status/toxicities at week 5/6/7 during RT and confirmed dysphagia status at weeks 2 and 6 post RT. RESULTS: Most (89.3%) patients did not require dysphagia support from SP services. Of the 18 patients identified on screening, only 7 (10.7%) had sufficient issues to return to SP care. Week 5/6/7 SP review confirmed low levels of toxicity. No post-treatment dysphagia was observed. There was an incremental benefit of A$15.02 for SP staff costs and a recovery of 5.31 appointments per patient. CONCLUSION: The pathway is a safe and effective service model to manage patients with HNC at low risk for dysphagia during RT, avoiding unnecessary SP appointments for the patient and service.

Radiotherapy for cutaneous head and neck cancer and parotid tumours: a prospective investigation of treatment-related acute swallowing and toxicity patterns.

PURPOSE: Reports of acute treatment-related dysphagia and toxicities for patients with parotid tumours or cutaneous head and neck cancer (HNC) are limited. This study aimed to describe the severity and timing of dysphagia and related toxicities experienced during radiotherapy for cutaneous HNC and parotid tumours, to inform the nature of future speech pathology (SP) service models required during treatment. METHODS: Prospective study of 32 patients with parotid tumours and 36 with cutaneous HNC undergoing curative non-surgical management. Dysphagia and acute toxicity data was collected weekly during treatment and at 2, 4 and 12 weeks post-treatment using the Functional Oral Intake Scale, diet descriptors and CTCAE v4.0. RESULTS: In both groups, minimal treatment toxicities (grades 0-1) were observed. Xerostomia and dysgeusia were the most frequently reported grade 2 toxicities. Only 3% of parotid patients and 6% with cutaneous HNC experienced grade 3 dysphagia. Full or soft texture diets were maintained by > 70% of patients in both groups. Symptoms peaked in the final week of treatment and rapidly improved thereafter. Apart from xerostomia < 10% of patients had any grade 2 toxicity at 12 weeks post-treatment. CONCLUSION: Patients in these subgroups of HNC experienced minimal treatment-related toxicity during radiotherapy. As such, the need for supportive symptom management by SP is low. Models that involve interdisciplinary surveillance of symptoms with referral to SP only when required may be best suited for these individuals to ensure issues are identified whilst minimising patient burden created by unnecessary routine SP appointments.

Helical intensity-modulated radiotherapy with concurrent chemotherapy for oropharyngeal squamous cell carcinoma: A prospective investigation of acute swallowing and toxicity patterns.

BACKGROUND: Conformal radiotherapy modalities may minimize treatment toxicities. The purpose of this study was to document the extent and timing of dysphagia and related toxicities during helical intensity-modulated radiotherapy (IMRT) with chemotherapy for oropharyngeal squamous cell carcinoma (SCC). METHODS: We conducted a prospective study of 76 patients with oropharyngeal SCC undergoing helical IMRT with chemotherapy. Dysphagia and acute toxicity data were collected weekly during treatment and at 2, 4, and 12 weeks posttreatment using the Functional Oral Intake Scale, diet descriptors, and Common Terminology Criteria for Adverse Events (CTCAE) version 4.0. RESULTS: Patients experienced maximum incidence of grade 3 dysphagia (61%), mucositis (30%), and thick saliva (38%), with grade 2 xerostomia (87%) and dysgeusia (97%). Only 14.5% were nil-by-mouth. Symptoms peaked in week 7 and improved thereafter. Grade 3 dysphagia was twice as common for T3 to T4 tumors compared with T2. CONCLUSION: Results confirm that patients with oropharyngeal SCC undergoing helical IMRT with chemotherapy continue to experience incidences of acute toxicities comparable with other conformal techniques, and need supportive cares.

Patterns of dysphagia and acute toxicities in patients with head and neck cancer undergoing helical IMRT±concurrent chemotherapy.

BACKGROUND: There is limited prospective data reporting the extent of treatment related toxicities associated with helical Intensity Modulated Radiotherapy (H-IMRT) for head and neck cancer (HNC). The study aim was to investigate severity, peak incidence and recovery patterns of dysphagia and related toxicities in patients undergoing H-IMRT±chemotherapy to examine when patients are experiencing symptoms requiring supportive clinical care. METHODS: Prospective study of 212 patients undergoing H-IMRT. Dysphagia and associated acute toxicities were monitored weekly during treatment and at weeks 2, 4 and 12 post treatment using the CTCAE v4, Functional Oral Intake Score and National Dysphagia Diet Descriptors. RESULTS: 75% experienced Grade 2-3 dysphagia. Over 70% had grade 2-3 dysguesia, xerostomia, and thick saliva, and >50% experienced grade 2-3 pharyngeal mucositis, oral mucositis, and nausea. 13% patients declined to NBM requiring complete enteral nutrition, 25% required enteral nutrition but maintained some form of oral intake. Symptoms peaked in final week of treatment, consistently improving thereafter, with the majority better than baseline by 12 weeks post-treatment. Concurrent chemotherapy at least doubles the odds of experiencing most symptoms excepting xerostomia, taste and fluid level. CONCLUSION: Despite advancements in radiation techniques, results confirm a high proportion of HNC patients experience dysphagia and related toxicities requiring supportive care during H-IMRT. Patients receiving H-IMRT alone experience a lower incidence of symptoms compared with those receiving concurrent chemotherapy. The data confirms the ongoing need for active on treatment monitoring with implications for the timing and intensity of patient support services.

Improving guideline sensitivity and specificity for the identification of proactive gastrostomy placement in patients with head and neck cancer.

BACKGROUND: Swallowing and nutrition guidelines for patients with head and neck cancer are available for identification of proactive gastrostomy placement in patients with high nutritional risk. The purpose of this study was to investigate improvements to the validity of these guidelines. METHODS: A multivariate analysis was fitted to the original dataset (n = 501) to examine the variables that may predict gastrostomy placement (eg, tumor site, treatment, sex, and age). Using these factors, the high risk category was modified and retrospectively validated in the same cohort to provide new measures of sensitivity and specificity. RESULTS: The following were positive predictors of gastrostomy placement: T3 (p = .01), T4 (p < .001), and chemoradiotherapy (p < .001). Laryngeal (p = .02) and skin cancer (p < .001) were negative predictors. Modification of the high risk definition improved sensitivity to 58% and maintained specificity at 92%. CONCLUSION: Minor modifications to the high risk definition in the guidelines have improved the guideline sensitivity for future use. © 2015 Wiley Periodicals, Inc. Head Neck 38: E1163-E1171, 2016.

Swallowing outcomes and PEG dependence in head and neck cancer patients receiving definitive or adjuvant radiotherapy +/- chemotherapy with a proactive PEG: a prospective study with long term follow up.

OBJECTIVES: This study examined long term swallowing outcomes of a cohort of head and neck cancer (HNC) patients identified at high risk of experiencing significant side effects from cancer treatment and were provided with a proactive PEG. MATERIAL AND METHODS: Ninety-five HNC patients receiving definitive or adjuvant radiotherapy +/- chemotherapy were identified for proactive PEG placement using validated guidelines and followed for up to 3years. Functional swallowing status was recorded at regular time points and data were collected on PEG use and duration in situ. RESULTS: Mean duration of enteral feeding was 125days. PEGs remained in situ for approximately 7months. PEG removal was achieved by 52% by 6months and 86% by 1year. Only 3 (3%) remained PEG dependent at 3years. Over half (55%) had resumed a full non-texture modified diet by PEG removal. CONCLUSION: Proactive PEG placement did not lead to high proportion of long term tube dependence in this high risk group and the majority achieved good swallowing outcomes.

Validated swallowing and nutrition guidelines for patients with head and neck cancer: identification of high-risk patients for proactive gastrostomy.

BACKGROUND: The "Swallowing and Nutrition Guidelines for Patients with Head and Neck Cancer" were developed to guide early identification and management of dysphagia and nutritional risk before, during, and after cancer treatment. The purpose of this study was to validate these guidelines. METHODS: Patients attending a Combined Head and Neck Clinic at a major tertiary hospital in 2007 to 2008 were assessed using the guidelines, with high-risk category patients recommended for proactive gastrostomy. Data were collected on guideline adherence, gastrostomy tube insertion, and weight. Sensitivity, specificity, and positive predictive value were calculated for validation. RESULTS: Proactive gastrostomy tubes were inserted in 173 of 501 patients (25%). Overall guideline adherence was 87%. High-risk category adherence was 75%. Validation outcomes were sensitivity 54%, specificity 93%, and positive predictive value 82%. CONCLUSION: The risk categories in the guidelines are valid to assist early identification of swallowing and nutritional risk and guide decision-making on proactive gastrostomy tube insertion.

Assessment of communication and swallowing post-laryngectomy: a telerehabilitation trial.

Ten laryngectomy patients were assessed using a purpose-designed, multimedia videoconferencing system incorporating a freestanding, self-focusing camera. Swallowing, stoma and communication status were assessed simultaneously by a remote clinician and face-to-face, by a second clinician at the patient's site. The remote trial took place over a distance of approximately 1700 km using a commercial 3G phone network. A satisfaction questionnaire was also completed. There was excellent agreement between the two assessing clinicians. Image quality obtained via the freestanding camera was rated as lower than direct observation, but it was sufficient to assess the stoma and status of the voice prosthesis. During the trial, occasional difficulties with audio delays and image distortion were experienced, although these were manageable. Both patient and clinician satisfaction with remote assessment was high. The results provide further evidence to support the use of telerehabilitation for evaluating the speech and swallowing status of laryngectomy patients following discharge from acute care.
