Dysphagia in Head and Neck Cancer Patients: Pretreatment Evaluation, Predictive Factors, and Assessment during Radio-Chemotherapy, Recommendations

Swallowing Kinematics in Male Patients with Total Laryngectomy

OBJECTIVE

The present study aimed to investigate the symptomatic swallowing complaints in individuals with total laryngectomy (TL) and reveal how swallowing kinematics differs between those with and without symptomatic dysphagia complaints.

METHODS

A total of 34 subjects with TL were included in the study. Swallowing kinematics of those with symptomatic swallowing complaints (Group 1) were compared to those without (Group 2). Kinematic parameters including pharyngeal transit duration (PTD), maximum pharyngeal constriction ratio (MPCR), upper esophageal sphincter opening ratio (UESOR), upper esophageal sphincter opening duration (UESOD), and bolus clearance ratio (BCR) were investigated from Videofluoroscopic Swallowing Study (VFSS) records via ImageJ software.

RESULTS

Symptomatic swallowing complaints were determined in 47.1% of the subjects (n = 16). Difficulty while swallowing solid foods and pills, diminished pleasure of eating, food getting stuck in the throat, and increased level of stress during swallowing were among the major swallowing complaints in the present cohort. PTD, MPCR, and BCR parameters were significantly higher in subjects with symptomatic swallowing complaints than those without.

CONCLUSION

These preliminary findings indicate that almost half of individuals with TL may have symptomatic swallowing complaints. The underlying pathophysiology of this phenomenon may be the devianced kinematic parameters including PTD, MPCR, and BCR in this population. Therefore, it is recommended to include the kinematic measurements in the dysphagia evaluation protocol in individuals with TL, most notably in those with symptomatic swallowing complaints.

Speech and swallowing intervention following oral cancer treatment: A survey of speech-language pathologists in Australia and New Zealand

PURPOSE

Treatment for oral cancer has debilitating effects on speech and swallowing, however, little is known about current speech-language pathology practice.

METHOD

An online survey of speech-language pathologists (SLPs) was disseminated via emails to speech pathology departments, social media platforms, and professional online forums. Survey questions captured demographics, service delivery, type and timing of speech and swallowing interventions, and influences and barriers to practice.

RESULT

Forty-three SLPs working in Australia (n = 41) and New Zealand (n = 2) completed the survey. SLPs recommended speech and swallowing compensatory strategies significantly more frequently than active intervention. Swallowing outcomes measures were either instrumental (n = 31, 94%) or performance ratings (n = 25, 76%), whereas speech was measured informally with judgements of intelligibility (n = 30, 91%). SLPs used a range of supports for their decision making, particularly expert opinion (n = 81, 38.2%). They reported time and staffing limitations (n = 55, 55%) and a lack of relevant evidence (n = 35, 35%) as the largest barriers to evidence-based service delivery.

CONCLUSION

There is variability amongst SLPs in Australia and New Zealand regarding rehabilitation of speech and swallowing for people with oral cancer. This study highlights the need for evidence-based guidelines outlining best practice for screening processes, active rehabilitation protocols, and valid outcome measures with this population.

Impact of Frailty on Post-Treatment Dysphagia in Patients with Head and Neck Cancer

In the rising and frail head and neck cancer (HNC) population, geriatric assessments are crucial. Frail HNC patients often experience dysphagia. The coexistence of dysphagia and frailty presents complex health challenges, however, there is limited evidence on the prognostic value of frailty on post-treatment dysphagia. This study explores the relationship between pre-treatment frailty status and post-treatment dysphagia in HNC patients. A retrospective data analysis from the OncoLifeS data-biobank at the University Medical Center Groningen of 242 patients diagnosed with HNC between 2014 and 2016. The study involved several physical, functional and psychological pre-treatment geriatric assessments, and frailty screening using the Groningen Frailty Indicator (GFI) and the Geriatric-8 screening tool (G8). Outcome measures were swallowing-related quality of life (HNSW-QoL) and toxicity-related dysphagia evaluations (CTCAE-D) at 3, 6, 12 and 24 months. Linear mixed-effects models assessed factors associated with HNSW-QoL and CTCAE-D. Frail patients consistently reported worse HNSW-QoL and CTCAE-D than non-frail patients over time, with symptoms increasing at 3 months, but gradually decreasing by 24 months. Frailty status (G8 or GFI) was a significant predictor for lower HNSW-QoL (β = 11.770 and 10.936, both p < 0.001), and lower CTCAE-D (β = 0.245, p = 0.058; β = 0.331, p = 0.019), respectively. In this study, frailty was found to be associated with a worse of swallowing-related quality of life, and with increased toxicity-related dysphagia. These findings provide insights for the identification of HNC patients at higher risk of post-treatment swallowing-related issues, and offer opportunities for optimizing their post-treatment swallowing outcomes.

Effects of chemoradiation and tongue exercise on swallow biomechanics and bolus kinematics

BACKGROUND

Common treatments for head and neck cancer (radiation and chemotherapy) can lead to dysphagia; tongue exercise is a common intervention. This study aimed to assess swallow biomechanics and bolus kinematics using a well-established rat model of radiation or chemoradiation treatment to the tongue base, with or without tongue exercise intervention.

METHODS

Pre- and post-treatment videofluoroscopy was conducted on 32 male Sprague-Dawley rats treated with radiation/chemoradiation and exercise/no exercise. Rats in the exercise groups completed a progressive resistance tongue training paradigm. Swallow biomechanics, bolus kinematics, jaw opening, and post-swallow respiration were assessed.

RESULTS

Both treatments impacted outcome measures; the addition of exercise intervention showed benefit for some measures, particularly in rats treated with radiation, vs. chemoradiation.

CONCLUSIONS

Radiation and chemoradiation can significantly affect aspects of deglutition; combined treatment may result in worse outcomes. Tongue exercise intervention can mitigate deficits; more intensive intervention may be warranted in proportion to combined treatment.

Dysphagia in Head and Neck Cancer

Dysphagia is a common symptom in patients with head and neck cancer that can significantly impact health outcomes and quality of life. The origin of dysphagia in these patients is often multifactorial, making diagnosis and management especially complex. The evaluating otolaryngologist should be well versed with the patient's neoplasm, comorbidities, and treatment history alongside dysphagia-specific imaging modalities. Management is often dynamic, requiring frequent monitoring, interprofessional collaboration, and a variety of supportive and invasive measures to achieve optimal outcomes.

The risk factors for silent aspiration: A retrospective case series and literature review

AIM

Evidence shows that 20%-30% of patients who aspirate do so silently. Research to date has not demonstrated clear evidence to indicate which patients are at higher risk of silent aspiration. Our aim was to use univariate logistic regression analysis of retrospective case review to determine potential patterns of silent aspiration.

MATERIALS AND METHODS

We conducted a retrospective analysis of 455 fiberoptic endoscopic evaluation of swallowing (FEES) reports. The patients were divided into four groups: G1 - neurological diseases (n = 93), G2 - head and neck surgery (n = 200), G3 - gastroenterological diseases (n = 94) and G4 - other patients (n = 68). Data included the occurrence or absence of saliva penetration or aspiration, of silent fluid/solid food penetration or aspiration, type of penetration or aspiration, occurrence of cranial nerve paresis, radiotherapy and tracheostomy. Univariate logistic regression was used to evaluate independent risk factors of silent aspiration in the study population. Three models with different independent variables were considered.

RESULTS

There is a statistically significant difference in the frequency of occurrence of silent penetration and aspiration within the groups (p < 0.001), with intraglutative being most frequent. Fluid and food penetration and aspiration correlated with saliva penetration and aspiration in all groups (p < 0.001). Cranial nerve paresis (IX and X), radiotherapy and tracheostomy correlate with saliva penetration and aspiration (p = 0.020 for cranial nerve paresis; p = 0.004 for radiotherapy; p < 0.001 for tracheostomy). One hundred and fifteen patients (45.81%) in the subgroup of patients with intraglutative aspiration had cranial nerve paresis (IX, X or IX-X).

CONCLUSIONS

Patients who should be prioritised or considered to be at a higher need of instrumental swallowing evaluation are those with IX and X cranial nerve paresis, tracheostomy and those who have had radiotherapy, with saliva swallowing problems, especially after paraganglioma, thyroid and parathyroid glands and middle and posterior fossa tumour surgery.

WHAT THIS PAPER ADDS

What is already known on the subject Clinical signs of penetration or aspiration include coughing, throat clearing and voice changes, while silent penetration or aspiration patients aspirate without demonstrating any clinical symptoms. The most common consequences of silent aspiration include aspiration pneumonia, recurrent lower respiratory tract infections and respiratory failure. Additionally, malnutrition and dehydration can be indicators of silent aspiration. Patients may unknowingly reduce their oral intake and lose weight. Retrospective studies have shown that 20%-30% of patients aspirate silently (e.g. patients after stroke, acquired brain injury, head and neck cancer treatment, prolonged intubation). Clinical examination of swallowing can miss up to 50% of cases of silent aspiration. What this paper adds to existing knowledge Currently, silent aspiration is often discussed in neurological literature, but its applications to head and neck surgery are limited. In this study, we identify head and neck surgery patients who should be prioritised or considered to be in higher need of instrumental swallowing evaluation due to a higher risk of silent aspiration. What are the potential or actual clinical implications of this work? Post-treatment structural changes can result in lower cranial nerve paresis (IX, X, XII) and face injury, in which vagus and glossopharyngeal nerves are injured. After tracheostomy and radiotherapy, patients with problems swallowing saliva need careful clinical examination, particularly cranial nerve examination.

The Acceptability of Behavioural Swallowing Interventions for Head and Neck Cancer Patients During Radiotherapy: A Qualitative Study Exploring Experiences of Clinical Trial Speech-Language Pathologists

The PRO-ACTIVE randomized clinical trial offers 3 swallowing therapies to Head and Neck Cancer (HNC) patients during radiotherapy (RT) namely: reactive, proactive low- ("EAT-RT" only) and high-intensity ("EAT-RT + exercises"). Understanding the experiences of the trial Speech-Language Pathologists (SLPs) will be useful to inform clinical implementation. This study assessed SLP opinions of acceptability and clinical feasibility of the 3 trial therapies. 8 SLPs from 3 Canadian PRO-ACTIVE trial sites participated in individual interviews. Using a qualitative approach, data collection and thematic analysis were guided by the Theoretical Framework of Acceptability. Member checking was conducted through a follow-up focus group with willing participants. Seven themes were derived: intervention coherence, burden, barriers/facilitators, self-efficacy, attitude, ethicality, and perceived effectiveness. SLPs felt all 3 therapies had potential benefit yet perceived more advantages of proactive therapies compared to reactive. Compared to exercises, SLPs particularly endorsed the EAT-RT component. A major barrier was keeping patients motivated, which was impacted by acute toxicity and sometimes conflicting instructions from the healthcare team. Strategies utilized by to overcome barriers included: scaling exercises and/or diet up/down according to the changing patient needs and communicating therapy goals with healthcare team. A model was derived describing the perceived acceptability of the swallowing therapies according to SLPs, based on the interconnection of main themes. Proactive therapies were perceived as more acceptable to trial SLPs, for facilitating patient engagement. The perceived acceptability of the swallowing therapies was related to seven interconnected aspects of providers' experience. These findings will inform the implementation and potential uptake of the PRO-ACTIVE swallowing therapies in clinical practice.

A core outcome set for patient-reported dysphagia for use in head and neck cancer clinical trials: An international multistakeholder Delphi study

BACKGROUND

Measuring dysphagia-related patient-reported outcomes (PROs) in Head and Neck Cancer (HNC) patients is challenging due to dysphagia's multidimensional impact, causing inconsistency in outcome reporting. To address this issue, this study derived a consensus-based core outcome set (COS) for patient-reported dysphagia in HNC clinical trials where swallowing is a primary or secondary endpoint.

METHODS

A sample of HNC clinicians, researchers, patients, and caregivers participated in a 2-Round Delphi technique. A Delphi survey, containing a comprehensive list of dysphagia-related PROs, was developed. In Round 1, participants rated item importance on a 5-point scale. Items rated ≥4 by >70% advanced to Round 2, where a consensus meeting addressed items with varied opinions, and the Delphi survey with remaining items was completed. Items rated ≥4 by >70% formed the final COS.

RESULTS

Forty-five participants from nine countries were recruited. After Round 1, 40 items were excluded and 64 advanced to Round 2. After Round 2, a 7-outcome COS was established, comprising the domains of dysphagia symptoms, health status and quality of life.

CONCLUSION

This study achieved consensus among HNC stakeholders on essential dysphagia PROs for HNC clinical trials. It is advisable to include these 7-core concepts in clinical trials involving people with HNC to facilitate treatment comparisons and data synthesis.

Screening oropharyngeal dysphagia in patients with head and neck cancer in a radiation oncology department

Background

Oropharyngeal dysphagia (OD) occurs in up to 40% of head and neck cancer (HNC) patients before treatment and remains a common symptom (23-60%) after oncological treatments, leading to several consequences. Early detection is essential for effective swallowing-rehabilitation and nutritional-support. The increased radiosensitivity of tumors associated with human papillomavirus (HPV) and advances in imaging techniques have stimulated research into deintensified strategies to minimize radiotherapy (RT) side effects. The purposes of the study are to establish the percentage of patients with HNC who are candidates to RT who are at risk of dysphagia [Eating Assessment Tool (EAT) score ≥ 3], determine if tumor location and previous surgery were related to a higher risk of dysphagia and if patients suffering severe toxicity during cancer therapy are at greater risk of posttreatment-dysphagia.

Materials and methods

Patients diagnosed of HNC who were referred to RT treatment at our Radiation Oncology Department were prospectively included. Questionnaire EAT-10 was filled in the first assessment used as a screening tool and repeated one month after treatment. Treatment toxicity was established according to common toxicity criteria adverse effects (CTCAE4.03).

Results

From November 2019 to January 2021, 72 patients were included. All completed pretreatment EAT-10 questionnaire. The mean (SD) score of the pretreatment EAT-10 was 7.26 ± 11.19 and 43.1% were at dysphagia risk. Patients with tumors located in the oral cavity, oropharynx and those that had received surgery prior to RT had higher risk than the rest of locations or those who had not previous surgery (p = 0.001 and p = 0.002, respectively). After oncological treatment 95.83% completed EAT-10 post-treatment and 45,6% showed positive EAT-10 score.

Conclusions

Patients with tumors in the oral cavity or oropharynx, presenting in advanced stage, and who previously received surgery are at higher risk of developing dysphagia. The EAT-10 is a simple tool that can help us identify those patients and refer them for an intensive evaluation to reduce dysphagia-consequences.

Early Improved Functional Outcomes in Head and Neck Cancer Patients with Primary Tumor Detection

OBJECTIVES

We characterize functional outcomes in head and neck cancer of unknown primary (CUP) based on primary site identification.

METHODS

In this retrospective study, CUP cases were categorized as known primaries (KP) if a tumor was localized after diagnostic workup or persisting unknown primaries (UP). Age, sex, HPV status, diagnostic methods, and treatments regimens were collected. Pretreatment and short-term posttreatment (3-6 months after completion of treatment) weights, PHQ-9, Eating Assessment Tool (EAT-10), and Voice Handicap Index (VHI-10) scores were compared between UP and KP.

RESULTS

Among 67 CUP patients, 35 (52.2%) had identified primaries (91.4% oropharyngeal and 8.6% nasopharyngeal). KP patients were younger (58 vs. 64, p = 0.04) and more likely to be HPV-positive (88.6% vs. 50%, p = 0.002). Overall detection rates were 16.7% for PET/CT, 34.7% for direct laryngoscopy, and 46.6% for transoral robotic oropharyngectomy. Diagnostic workup was not significantly different between groups. Patients with KP received smaller intermediate radiation dose volumes (436.5 vs. 278.9 cc, p = 0.03) and lower doses to the cricopharyngeal muscle (41.6 vs. 24.6 Gy, p = 0.03).Pretreatment weights, PHQ-9, EAT-10, and VHI-10 scores did not differ between groups. However, posttreatment, UP had greater relative weight loss (-14.1% vs. -7.6%, p = 0.032), higher EAT-10 scores (12.5 vs. 3, p = 0.004), and higher PHQ-9 scores (6 vs. 1.4, p = 0.017). Specifically, UP reported more stressful swallowing, difficulty swallowing solids and pills, and swallowing affecting public eating.

CONCLUSION

KP patients experienced less weight loss, depression, and reduced swallowing dysfunction, highlighting an early functional benefit of primary tumor identification likely driven by reduced radiation treatment volumes.

Feasibility of Achieving Dose Constraints for Dysphagia Aspiration-Related Structures and Its Clinical Significance in Intensity-Modulated Radiotherapy Planning of Head and Neck Cancer

Introduction Dysphagia is commonly seen in patients with head and neck cancers after undergoing chemoradiotherapy and is often under-reported and also not given clinical importance. The quality of life of the patients can be significantly improved if the required dose constraints to the dysphagia aspiration-related structures (DARS) are achieved. The present study was conducted in order to determine the feasibility of achieving the dose constraints to DARS between the standard intensity-modulated radiotherapy (st-IMRT) arm and the dysphagia-optimized IMRT (do-IMRT) arm. Material and methods Sixty patients with head and neck cancer were recruited and randomized into two groups: In one group called the st-IMRT, constraints were not given to DARS, and in the other group called the do-IMRT, constraints were given to DARS. Treatment was given in the form of chemoradiation with a dose of 70 Gy in 35 fractions by IMRT technique, over seven weeks, 2 Gy per fraction along with weekly concurrent Cisplatin (35 mg/m2) in both the groups. Step and shoot IMRT setup was used for planning, and the system used for planning was Eclipse 13.6 (Varian Medical System, Inc., Palo Alto, CA, US); progressive resolution optimizer algorithm was used for optimization, and Anisotropic Analytical Algorithm algorithm was used for dose calculation. Truebeam was used for treatment delivery. DARS dosimetric parameters assessed were Dmean, V30, V50, V60, V70, D50, and D80. Radiation-induced toxicities to the skin, mucosa, larynx, salivary gland, and dysphagia and hematological toxicities were assessed in between both the groups during and after radiotherapy up to six months based on Common Terminology Criteria for Adverse Effects v5.0. p-values were calculated using the unpaired T-test. Results In the cohort of 60 patients with head and neck cancers, 95% were males. Dosimetric parameters of the planning target volume (PTV) were compared but were not found to be significant. In the dosimetry of the organs at risk, a p-value of some structures was found to be significant although the doses received were well within the tolerable limits in both arms. DARS dosimetry V60 and V70 of the inferior constrictor muscle was found to be statistically significant (p=0.01 and 0.008, respectively). V60 and V70 of larynx were also statistically significant (p=0.009 and 0.000, respectively). V70 and D50 of cricopharyngeus were found to be statistically significant (p=0.01 and 0.03, respectively), V30 and V60 for combined pharyngeal constrictor muscles were found to be statistically significant (p=0.02 and 0.01), and lastly, V60 for combined DARS was also significant (p=0.004). Post-treatment 33.3% of patients in the st-IMRT arm required Ryle's tube placement. No grade 4 toxicities were seen in either arm regarding hematological toxicities, acute or chronic radiation-induced toxicities. In site-wise comparison of doses, the p-value was not found to be significant in patients with oropharyngeal and oral cavity carcinomas but was found to be statistically significant in the larynx and hypopharynx subsites. Conclusion The feasibility of achieving dose constraints to the DARS was seen in cases of laryngeal and hypopharyngeal cancers where the constrictor muscles were at a distance from the PTV. Further, the feasibility of achieving dose constraints may be seen in lower-dose prescriptions either in postoperative cases or in low-risk clinical target volume nodal volumes.

How age affects health-related-quality-of-life outcomes in maxillomandibular reconstructive surgery

INTRODUCTION

Maxillomandibular reconstruction has various functional, aesthetic, and psychosocial effects that can decrease patients' health-related quality of life (HRQOL). The aim of this study was to compare HRQOL outcomes in older and younger patients undergoing maxillomandibular reconstruction.

METHODS

A cross-sectional study of patients undergoing maxillomandibular reconstruction surgery between November 2008 and January 2021 was conducted. Participants completed the FACE-Q Head and Neck Cancer Module, M.D. Anderson Dysphagia Inventory (MDADI), and Speech Handicap Index (SHI). Results from these instruments were used to compare HRQOL outcomes in old (≥70 years) and young (<70 years) patients.

RESULTS

Ninety-nine patients who underwent maxillomandibular reconstruction completed the instruments (response rate 50%), of which 33 (33%) were aged ≥70 years. Older age was associated with improved FACE-Q speaking (+11.3, P = 0.045), FACE-Q cancer worry (-9.97, P = 0.050), and SHI score (-16.6, P = 0.013). After adjusting for the effect of radiotherapy, age was associated with improved FACE-Q speaking (+16.8, P = 0.012), FACE-Q smiling distress (+12.6, P = 0.040), FACE-Q worry (-11.0, P = 0.032), and SHI scores (-18.4, P = 0.004). Older age was associated with an increased likelihood of postoperative complications (odds ratio (OR) = 2.9, P = 0.02) and medical complications (OR = 4.6, P = 0.012).

CONCLUSION

In patients undergoing maxillomandibular reconstruction, older age (≥70 years) was associated with better HRQOL outcomes in domains relating to speech and cancer worry. In all other HRQOL outcomes, the two age groups performed similarly.

Head-and-neck Cancer in the Emergency Department: A Contemporary Review of Common Presentations and Management

Head-and-neck cancer (HNC) can present with life.threatening symptoms in the emergency department. Patients can sometimes be misdiagnosed with pulmonary disease due to similar signs and symptoms, ultimately leading to delayed diagnosis and potentially devastating consequences. Reasons for this include lack of awareness of patient risk factors and knowledge of the myriad of presenting complaints in the disease process among physicians working in primary care and in the emergency department. This article explores the contemporary risk factors and common presenting symptoms and discusses initial management for a patient with potential head-and-neck malignancy. Emergency presentations of HNC are wide ranging and can overlap with common respiratory pathologies. Clinician awareness of this can assist the team in deciding what appropriate examination and investigations are required to reduce the risk of delaying diagnosis and further treatment.

Swallowing in advanced oral cancers: A prospective observational study

BACKGROUND

Advanced head and neck cancers are known to cause swallowing dysfunction due to anatomical and post-treatment changes. Literature is sparse on post-surgical and/or multi-modality therapy-associated swallowing function in advanced oral cancers. We conducted this study to longitudinally assess and compare the pre- and post-therapy swallowing dysfunction associated with locally advanced oral cancers.

METHODS AND MATERIAL

A prospective observational longitudinal study was conducted at a tertiary cancer center from 2017 to 2018 including treatment-naive cT4a oral cancer patients (AJCC 7th edition). The assessment was done pre-surgery, post-surgery, and post-adjuvant setting as per the scales (Dysphagia score, Penetration aspiration scale, and Yale pharyngeal residue (vallecular and pyriform fossa).

RESULTS

Of the 30 patients in the study, 47.4%, 47.4%, 52.6%, and 47.4% experienced deterioration of Dysphagia score, Penetration-Aspiration Scale (PAS), vallecula residue, and pyriform residue scores in the postoperative period. And 52.6%, 47.4%, 68.4%, and 57.9% had inferior dysphagia score, PAS, vallecula, and pyriform residue scores even 6 months after completion of adjuvant therapy. The dysphagia score correlated well with other objective assessment scores at different time points.

CONCLUSION

Swallowing functions are significantly affected by surgery and adjuvant therapy and continue to be affected even 6 months after completion of treatment. Appropriate rehabilitation and intervention must be offered to patients to reduce this problem. Dysphagia scores can predict the swallowing status similar to other objective assessments.

Dysphagia at 1 Year is Associated With Mean Dose to the Inferior Section of the Brain Stem

PURPOSE

Dysphagia is a common toxicity after head and neck (HN) radiation therapy that negatively affects quality of life. We explored the relationship between radiation therapy dose to normal HN structures and dysphagia 1 year after treatment using image-based datamining (IBDM), a voxel-based analysis technique.

METHODS AND MATERIALS

We used data from 104 patients with oropharyngeal cancer treated with definitive (chemo)radiation therapy. Swallow function was assessed pretreatment and 1 year posttreatment using 3 validated measures: MD Anderson Dysphagia Inventory (MDADI), performance status scale for normalcy of diet (PSS-HN), and water swallowing test (WST). For IBDM, we spatially normalized all patients' planning dose matrices to 3 reference anatomies. Regions where the dose was associated with dysphagia measures at 1 year were found by performing voxel-wise statistics and permutation testing. Clinical factors, treatment variables, and pretreatment measures were used in multivariable analysis to predict each dysphagia measure at 1 year. Clinical baseline models were found using backward stepwise selection. Improvement in model discrimination after adding the mean dose to the identified region was quantified using the Akaike information criterion. We also compared the prediction performance of the identified region with a well-established association: mean doses to the pharyngeal constrictor muscles.

RESULTS

IBDM revealed highly significant associations between dose to distinct regions and the 3 outcomes. These regions overlapped around the inferior section of the brain stem. All clinical models were significantly improved by including mean dose to the overlap region (P ≤ .006). Including pharyngeal dosimetry significantly improved WST (P = .04) but not PSS-HN or MDADI (P ≥ .06).

CONCLUSIONS

In this hypothesis-generating study, we found that mean dose to the inferior section of the brain stem is strongly associated with dysphagia 1 year posttreatment. The identified region includes the swallowing centers in the medulla oblongata, providing a possible mechanistic explanation. Further work including validation in an independent cohort is required.

Decisional regret, symptom burden, and quality of life following transoral robotic surgery for oropharyngeal cancer

BACKGROUND

Transoral robotic surgery (TORS) has equivalent oncologic control to radiotherapy with potential for improved quality of life (QOL) and lower patient-reported decisional regret.

METHODS

Cross-sectional study between 2016 and 2021 of TORS patients with early-stage oropharyngeal squamous cell carcinoma who completed the Decision Regret Scale (DRS), M. D. Anderson Dysphagia Inventory (MDADI), and University of Washington Quality of Life (UW-QOL). The median time from treatment to questionnaire completion was 1.8 years (IQR 1.4-3.3, range 1.0-5.6).

RESULTS

Of 65 patients, 84.6% expressed no or mild decisional regret. Regret was not associated with clinical parameters or adjuvant treatment but was correlated with MDADI (τavg = -0.23, p < 0.001) and UW-QOL (τavg = -0.27, p < 0.001). Worse MDADI was associated with older age and worse UW-QOL was associated with multi-site operation and shorter time to survey.

CONCLUSIONS

Overall, the TORS cohort expressed very limited decisional regret. DRS scores were unaffected by clinicodemographics or additional adjuvant therapies, but decision regret was correlated with worse QOL and worse swallowing.

Multi-Domain Screening: Identification of Patient's Risk Profile Prior to Head-and-Neck Cancer Treatment

BACKGROUND

Head-and-neck cancer (HNC) can give rise to oropharyngeal dysphagia (OD), malnutrition, sarcopenia, and frailty. Early identification of these phenomena in newly diagnosed HNC patients is important to reduce the risk of complications and to improve treatment outcomes. The aim of this study was (1) to determine the prevalence of the risk of OD, malnutrition, sarcopenia, and frailty; and (2) to investigate the relation between these phenomena and patients' age, performance status, and cancer group staging.

METHODS

Patients (N = 128) underwent multi-domain screening consisting of the Eating Assessment Tool-10 for OD, Short Nutritional Assessment Questionnaire and BMI for malnutrition, Short Physical Performance Battery and Hand Grip Strength for sarcopenia, and Distress Thermometer and Maastricht Frailty Screening Tool for frailty.

RESULTS

26.2%, 31.0%, 73.0%, and 46.4% of the patients were at risk for OD, malnutrition, sarcopenia, or frailty, respectively. Patients with an advanced cancer stage had a significantly higher risk of OD and high levels of distress prior to cancer treatment.

CONCLUSIONS

This study identified the risk profile of newly diagnosed HNC patients using a standardized 'quick and easy' multi-domain screening prior to cancer treatment.

Late laryngeal dysfunction in head and neck cancer survivors

Objectives

Head and neck cancer (HNC) survivorship issues are areas of increasing research interest. Laryngeal dysfunction in HNC patients is particularly important given the importance of the larynx in voice, swallowing, and airway protection. The objective of our study is to characterize late laryngeal dysfunction in a cohort of long-term HNC survivors.

Methods

HNC survivors who were at least 2 years post-treatment were recruited prospectively for standard collection of videolaryngoscopy findings, videofluoroscopic swallowing studies, and assessment of clinical outcomes. Descriptive statistics were performed and clinical presentation and outcomes were compared between survivors >10 years and <10 years post-treatment. Additional factor analysis to correlate clinical outcomes with clinical variables was performed.

Results

Thirty participants were analyzed with a mean age of 66 years. The majority were male (80%) patients treated for oropharyngeal squamous cell carcinoma (67%). Within the cohort, 43% underwent primary chemoradiation therapy and had 13% radiation alone. Common presenting symptoms included swallowing dysfunction (83%), voice change (67%), and chronic cough (17%). Laryngeal findings on video laryngoscopy include vocal fold motion abnormalities (VFMA) in over half of participants (61%) and mucosal changes in 20%. A weak correlation was found between time since treatment and laryngeal dysfunction (r = .182, p = .34), and no correlation was found between age, sex, time since treatment, or primary site and the presence or absence of VFMA, G-tube status, or tracheostomy-tube status.

Conclusion

Late laryngeal dysfunction in HNC survivors contributes to significant morbidity, is difficult to treat, and remains static decades after treatment for their original cancer.

Lay Summary

The voice-box, or the larynx, plays an important role in voice, swallowing and airway protection. It is particularly vulnerable to radiation-related damage and changes. This study demonstrates the sequelae of long-term damage of the larynx in head and cancer survivors.

Head and Neck Low Grade Chondrosarcoma-A Rare Entity

Chondrosarcoma represents approximately 0.1% of all neoplasms of the head and neck and is considered a rare disease with a relatively good prognosis. The 5-year overall survival (OS) rate is estimated at 70-80%, being considered a disease with a low growth rate. Approximately 13% of all cases of chondrosarcoma are located in the region of the head and neck. We present the case of a 30-year-old patient without a medical history who reported dysphagia, swallowing difficulty, neck mass sensation and dysphonia that started insidiously after an upper respiratory tract infection. Subsequently, the patient was diagnosed with a low-grade glosso-epiglottic region chondrosarcoma and was multimodally treated with surgery followed by chemotherapy and radiotherapy. The radiation treatment was delivered with a Rokus M40 former Soviet Union cobalt machine without any image guidance capabilities. The inability to obtain resection margin information justified an aggressive adjuvant treatment with chemotherapy and radiotherapy. The early loss from the oncological record without recurrence of the disease could be associated in this case with the consequence of a major complication, of which we could assume an aspiration pneumonia secondary to a dysphagia associated with an aggressive multidisciplinary treatment. Large tumor size and positive resection margins (R1 resection) are risk factors that support an intensive adjuvant approach in order to reduce the risk of recurrence, but the low grade of tumor associated with a lower risk of recurrence as well as the adverse events (AE) of adjuvant radiotherapy and chemotherapy justify a more reserved therapeutic approach. Taking into account the longer life expectancy of these patients, it is recommended to use a more conformal irradiation technique in order to reduce doses to radiosensitive structures as well as to omit elective neck irradiation, taking into account the lower risk of lymph node involvement. The lack of guidelines, which include very rare tumors including low grade chondrosarcoma of the head and neck, makes a unified approach difficult, but the data presented in case reports could contribute to choosing the regimen that offers the best therapeutic ratio.

Longitudinal changes in swallowing function after surgery and proactive swallowing therapy for oral cancer

BACKGROUND

This study aimed to describe and explore the longitudinal changes in swallowing function among patients with oral cancer who underwent surgery and proactive swallowing therapy from baseline to 1-year postoperation.

METHODS

We retrospectively studied 118 patients over a 4.5-year duration. Swallowing functional assessment including 10-item Eating Assessment Tool (EAT-10), Functional Oral Intake Scale (FOIS), M. D. Anderson Dysphagia Inventory, and Modified Barium Swallow Impairment Profile (MBSImP™) was performed at baseline, 1-month, 6-month, and 1-year postoperatively.

RESULTS

All swallowing parameters worsened 1-month postoperation. EAT-10, FOIS, and MBSImP™ oral and pharyngeal impairment scores improved significantly compared with 1-month postoperation at 6 months. Other swallowing parameters, except for weight, did not differ significantly from baseline at 6 months. The rate of tube-feeding dependency was 11.5% and 5.6% at 1 and 6 months postoperation, respectively.

CONCLUSIONS

Periodic swallowing functional assessments help delineate the longitudinal changes in swallowing functional outcomes.

Swallowing Function After Treatment of Laryngeal Cancer

Dysphagia is a common functional outcome following treatment of laryngeal cancer. Despite curative advances in both nonsurgical and surgical approaches, preserving and optimizing swallowing function is critical. Understanding the nature and severity of dysphagia depending on initial tumor staging and treatment modality and intensity is crucial. This chapter explores current evidence on the acute and chronic impacts of treatments for laryngeal cancer on swallow function, as well as the medical and nonmedical management of dysphagia in this population.

Expert Consensus Statement: Management of Dysphagia in Head and Neck Cancer Patients

OBJECTIVE

To develop an expert consensus statement (ECS) on the management of dysphagia in head and neck cancer (HNC) patients to address controversies and offer opportunities for quality improvement. Dysphagia in HNC was defined as swallowing impairment in patients with cancers of the nasal cavity, paranasal sinuses, nasopharynx, oral cavity, oropharynx, larynx, or hypopharynx.

METHODS

Development group members with expertise in dysphagia followed established guidelines for developing ECS. A professional search strategist systematically reviewed the literature, and the best available evidence was used to compose consensus statements targeted at providers managing dysphagia in adult HNC populations. The development group prioritized topics where there was significant practice variation and topics that would improve the quality of HNC patient care if consensus were possible.

RESULTS

The development group identified 60 candidate consensus statements, based on 75 initial proposed topics and questions, that focused on addressing the following high yield topics: (1) risk factors, (2) screening, (3) evaluation, (4) prevention, (5) interventions, and (6) surveillance. After 2 iterations of the Delphi survey and the removal of duplicative statements, 48 statements met the standardized definition for consensus; 12 statements were designated as no consensus.

CONCLUSION

Expert consensus was achieved for 48 statements pertaining to risk factors, screening, evaluation, prevention, intervention, and surveillance for dysphagia in HNC patients. Clinicians can use these statements to improve quality of care, inform policy and protocols, and appreciate areas where there is no consensus. Future research, ideally randomized controlled trials, is warranted to address additional controversies related to dysphagia in HNC patients.

Relationship Between Pharyngeal Residues Assessed by Bolus Residue Scale or Normalized Residue Ratio SCALE and Risk of Aspiration in Head and Neck Cancer Who Underwent Videofluoroscopy

Dysphagia affects 60-75% of patients treated for head and neck cancer (HNC). We aimed to evaluate the association between residue severity and airway invasion severity using a videofluoroscopic swallowing study and identify risk factors for poor penetration-aspiration outcomes in patients with dysphagia treated for HNC. Penetration-Aspiration Scale (PAS) was used to assess airway invasion severity, while residue severity was assessed using both the Bolus Residue Scale (BRS) for residue location and the Normalized Residue Ratio Scale (NRRS) for residue amount. Relevant covariates were adjusted in the logistic regression models to account for potential confounding. Significantly higher abnormal PAS was reported for increased piriform sinus NRRS (NRRSp) [odds ratio (OR), 4.81; p = 0.042] with liquid swallowing and increased BRS value (OR, 1.52; p = 0.014) for semi-liquid swallowing in multivariate analysis. Tumor location, older age, and poorer Functional Oral Intake Scale (FOIS) were significant factors for abnormal PAS in both texture swallowings. After adjusting for confounding factors (sex, age, and FOIS score), NRRS model in liquid swallowing (area under the curve [AUC], 0.83; standard error = 0.04, 95% confidence interval [CI]: 0.75, 0.91) and BRS in semi-liquid swallowing (AUC, 0.83; SE = 0.04; 95% CI: 0.76, 0.91) predicted abnormal PAS. The results indicate that while assessing residue and swallowing aspiration in patients with HNC, it is important to consider age, tumor location, and functional swallowing status. The good predictability of abnormal PAS with BRS and NRRS indicated that residue location and amount were both related to the aspiration event in patients with HNC.

Intra and interobserver agreement of the Dynamic Imaging Grade of Swallowing Toxicity Scale (DIGEST) in fiberoptic endoscopic evaluation of swallowing (FEES): the importance of observer-tailored training

PURPOSE

The Dynamic Imaging Grade of Swallowing Toxicity (DIGEST) is a scale to quantify the severity of pharyngeal dysphagia in head and neck cancer (HNC) patients. This study (1) described the training process of the observers for DIGEST in fiberoptic endoscopic evaluation of swallowing (FEES), (2) determined observer agreement on the DIGEST in FEES, (3) explored the effect of bolus consistency on observer agreement, and 4) explored criterion validity of the DIGEST in FEES.

METHODS

Twenty-seven dysphagic HNC patients were enrolled. Two observers completed a training program for DIGEST in FEES. Observer agreement on the Penetration-Aspiration Scale (PAS), percentage of pharyngeal residue (PPR), and DIGEST grades was determined using linearly weighted Cohen's kappa coefficient (κ).

RESULTS

Due to insufficient observer agreement after the first measurement attempt, additional training was organized using an elaborated manual with descriptions of the visuoperceptual variables, thereby improving observer agreement. Intraobserver agreement was almost perfect on the PAS (κ = 0.86-0.88) and PPR (κ = 0.84-0.86). Interobserver agreement was substantial on the PAS (κ = 0.78), almost perfect on the PPR (κ = 0.82), substantial on the safety grade (κ = 0.64), almost perfect on the efficiency grade (κ = 0.85), and substantial on the summary grade (κ = 0.71). Bolus consistency had an effect on observer agreement. A significant correlation was found between DIGEST efficiency grade and EAT-10.

CONCLUSION

The DIGEST showed to be a reproducible measurement for FEES in terms of observer agreement. However, agreement between novice observers on the DIGEST was only reached after specific observer-tailored training. Observer agreement should be analyzed by taking bolus consistency into account during training, as this might affect the interpretation of the outcome. A manual with well-defined descriptions can optimize the reproducibility of DIGEST measurements.

Oral Somatosensory Alterations in Head and Neck Cancer Patients-An Overview of the Evidence and Causes

Food-related sensory alterations are prevalent among cancer patients and negatively impact their relationship with food, quality of life, and overall health outcome. In addition to taste and smell, food perception is also influenced by somatosensation comprising tactile, thermal, and chemesthetic sensations; yet studies on oral somatosensory perception of cancer patients are lacking to provide patients with tailored nutritional solutions. The present review aimed to summarise findings on the oral somatosensory perception of head and neck cancer (HNC) patients and the potential aetiologies of somatosensory alterations among this population. Subjective assessments demonstrated alterations in oral somatosensory perception such as sensitivity to certain textures, spices, and temperatures. Physiological changes in oral somatosensation have been observed through objective assessments of sensory function, showing reduced localised tactile function and thermal sensitivity. Changes in whole-mouth tactile sensation assessed using texture discrimination and stereognosis ability seem to be less evident. Available evidence indicated oral somatosensory alterations among HNC patients, which may affect their eating behaviour, but more studies with larger sample sizes and standardised assessment methods are needed. Unlike other types of cancers, sensory alterations in HNC patients are not only caused by the treatments, but also by the cancer itself, although the exact mechanism is not fully understood. Prevalent oral complications, such as xerostomia, dysphagia, mucositis, and chemosensory alterations, further modify their oral condition and food perception. Oral somatosensory perception of cancer patients is an under-investigated topic, which constitutes an important avenue for future research due to its potential significance on eating behaviour and quality of life.

Dysphagia in Solid Tumors Outside the Head, Neck or Upper GI Tract: Clinical Characteristics

CONTEXT

Dysphagia is common in cancer, but underlying pathophysiology and manifestations within patients are unknown.

OBJECTIVES

To examine dysphagia characteristics in those with solid malignancies outside the head, neck and upper gastrointestinal tract.

METHODS

Seventy-three individuals with dysphagia (46 male, 27 female, aged 37-91) were recruited from a parent trial conducted in two acute hospitals and one hospice. Cranial nerve function, Oral Health Assessment Tool (OHAT), Mann Assessment of Swallowing Ability (MASA) and Functional Oral Intake Scale (FOIS) evaluated swallow profile.

RESULTS

Only 9/73 (12%) had documented dysphagia prior to study enrollment. MASA risk ratings found n=61/73 (84%) with dysphagia risk and n=22/73 (30%) with aspiration risk. Food texture modification was required for n=34/73 (47%), fluid texture modification for n=1/73 (1%). Compensatory strategies for food were needed by n=13/73 (18%) and for fluids by n=24/73 (33%). Cranial nerve deficits were present in n=43/73 (59%). Oral health problems were common, with xerostomia in two-thirds. Worse dysphagia on MASA was associated with disease progression, affecting hospice, and palliative care the most. Worse performance status was indicative of poorer MASA raw score (P<0.001, OR 2.2, 95% CI 1.5-3.4), greater risk of aspiration (P=0.005, OR 2.1, 95% CI 1.3-3.6) and lower FOIS (P=0.004, OR 2.0, 95% CI 1.2-3.2).

CONCLUSION

Dysphagia management in those with cancer requires robust assessment to uncover clinically important needs like food texture modification and safe swallowing advice. Better assessment tools should be developed for this purpose. Oral health problems should be routinely screened in this population since they exacerbate dysphagia.

Flourishing in head and neck cancer survivors

Background

There is a growing cohort of head and neck cancer (HNC) patients affected by late‐ and long‐term posttreatment side effects. Our study evaluates the relationship between the demographics, clinical characteristics, and posttreatment symptom burden with the subjective sense of flourishing among HNC survivors.

Methods

A cross‐sectional, single‐center study of adult survivors of squamous cell cancer of the oral cavity, oropharynx, and larynx/hypopharynx who completed the Secure Flourishing Index (SFI) and patient‐reported outcomes related to depression, anxiety, swallowing dysfunction, neck disability, and insomnia between November 2020 and April 2021.

Results

A total of 100, predominantly male (86%), survivors with an average age of 63.0 ± 9.6 were included in the study. Univariable analysis showed a significant association between higher flourishing scores and advanced age (95% CI: [0.011, 0.84], p = 0.0441), normal diet (95% CI: [5.79, 31.18], p = 0.0149), employment (95% CI: [1.24, 17.20], p = 0.0239), higher income (95% CI: [7.30, 27.72], p = 0.0248), and decreased reported difficulty paying for needs (95% CI: [−33.46, −18.88], p < 0.001). Flourishing was inversely associated with higher symptoms of depression (95% CI: [−2.23, −1.15], p < 0.001), anxiety (95% CI: [−1.92,‐0.86], p < 0.001), swallowing dysfunction (95% CI: [−0.77, −0.26], p < 0.001), neck disability (95% CI: [−1.05, −0.35], p < 0.001), and insomnia (95% CI: [−1.12, −0.22], p = 0.004) in the multivariable analysis.

Conclusions

Common late‐ and long‐term side effects of HNC treatment and financial hardship are associated with lower levels of flourishing or a more negative perception of life after treatment. Results highlight the importance of symptom burden for survivors' overall evaluation of their quality of life.

Psychometric properties of patient-reported outcome measures for dysphagia in head and neck cancer: a systematic review protocol using COSMIN methodology

BACKGROUND

Dysphagia (swallowing difficulty) is one of the most common and debilitating sequelae of head and neck cancer (HNC). Patient-reported outcome measures (PROMs) are a fundamental component of dysphagia outcomes evaluation, as they inform treatment consequences that cannot be captured by objective clinician measures. Many PROMs for dysphagia in HNC are available, but their validity is unclear. As a consequence, the selection of the most appropriate PROM for dysphagia in HNC is complex and often based on the clinician's personal preferences, rather than on valid psychometric properties. This protocol describes a systematic review aiming at (1) identifying PROMs specific to dysphagia symptoms, swallowing functional status, swallowing-related health status, and swallowing-related quality of life in HNC, (2) mapping them to our conceptual framework of dysphagia-related PROs, and (3) appraising their psychometric properties using the Consensus Based Standards for the Selection of Health Measurement Instrument (COSMIN) methodology.

METHODS

Six electronic databases will be searched from inception to December 2020 for all primary studies in any language and design detailing PROM development, reliability, validity, feasibility, interpretability, and/or cross-cultural adaptation. Eligibility criteria will target PROMs for patients with HNC (≥ 90% of the study sample) with ≥ 20% of their items pertaining to swallowing. Two independent raters will screen abstract and full texts and a third rater will resolve discrepancies. Data will be extracted on study, sample and PROM characteristics, and results of psychometric testing. PROMs will be mapped to our conceptual framework. The methodological quality of included PROMs and their psychometric properties will be appraised using the COSMIN risk of bias checklist and evidence will be summarized using a modified Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach.

DISCUSSION

This systematic review will provide a summary of existing dysphagia-related PROMs for people with HNC and a comprehensive account of their psychometric properties. We will provide recommendations on PROMs selection which will aid healthcare professionals to the most appropriate PROM based on its validity, reliability, feasibility, interpretability and suitability for clinical and research settings. Further recommendations will be made on areas of measurement property requiring further testing.

Evaluation of Objective and Subjective Swallowing Outcomes in Patients with Dysphagia Treated for Head and Neck Cancer

We evaluated objective and subjective swallowing function outcomes in patients with dysphagia treated for head and neck cancer (HNC) and identified risk factors for poor swallowing outcomes. Patients undergoing videofluoroscopic swallowing studies (VFSS) between January 2016 and March 2021 were divided into four groups according to primary tumor sites; post-treatment dysphagia was assessed. The penetration–aspiration scale (PAS) and bolus residue scale (BRS) were used to objectively assess swallowing function through VFSS. The Functional Oral Intake Scale (FOIS) was used for subjective analyses of swallowing statuses. To account for potential confounding, important covariates were adjusted for in logistic regression models. Oropharyngeal tumors were significantly more likely to have poor PAS and BRS scores than oral cavity tumors, and the patients with nasopharyngeal tumors were significantly less likely to have poor FOIS scores. Old age, having multiple HNCs, and a history of radiotherapy were associated with an increased odds of poor PAS scores (for all types of swallows), poor BRS scores (for semiliquid and solid swallows), and poor FOIS scores, respectively. This indicates using only subjective assessments may not allow for accurate evaluations of swallowing function in patients treated for HNC. Using both objective and subjective assessments may allow for comprehensive evaluations.

Functional swallowing outcomes related to radiation exposure to dysphagia and aspiration-related structures in patients with head and neck cancer undergoing definitive and postoperative intensity-modulated radiotherapy

BACKGROUND

The relationship between swallowing outcomes and radiotherapy dose to dysphagia and aspiration-related structures (DARS) may be different following definitive versus postoperative radiotherapy (PORT) for mucosal head and neck cancer (HNC) and has not been well-studied.

METHOD

Patient- and clinician-reported swallowing measures were prospectively collected at six time points from baseline to 24 months postradiotherapy HNC. Radiotherapy plans were retrospectively analyzed to assess dose delivered to DARS. The association between swallowing outcomes and participant demographics, tumor characteristics, and radiotherapy dose in definitive and postoperative treatment cohorts was assessed.

RESULTS

Ninety-three participants who received radiotherapy for HNC were included in the analysis (n = 49 definitive radiotherapy for laryngeal/pharyngeal primary tumors and n = 44 postoperative PORT for predominantly oral cavity/salivary gland tumors). Participants undergoing PORT had lower doses to DARS than those undergoing definitive RT. High dose to the pharyngeal constrictors and base of tongue for definitive RT and the esophageal inlet, supraglottic larynx and cervical esophagus for the PORT group were associated with worse swallowing function.

CONCLUSION

Radiation dose to DARS is associated with post-treatment swallowing outcomes. These dose/outcome relationships may vary between the definitive and postoperative settings.

Translation and Validation of the Indonesian MD Anderson Dysphagia Inventory (MDADI) in Head and Neck Cancer Patients with Swallowing Disorders

Introduction  Dysphagia is common in head and neck cancer patients; it is associated with significant morbidity, including quality of life. Several instruments can be used to assess the quality of life of dysphagia patients, including the M.D Anderson dysphagia inventory (MDADI) questionnaire, which is sufficiently valid and reliable to improve the quality of life of patients with neurological disorders and head and neck cancer.

Objective  The purpose of the present study is to perform adaptation, cultural translation, and validation of the MDADI questionnaire for the Indonesian language.

Methods  This cross-sectional study assessed the validity and reliability of the MDADI Indonesian adaptation instrument in head and neck cancer patients with swallowing disorders in the Otorhinolaryngology clinic of the Dr. Sardjito hospital, Yogyakarta, from May to August 2019.

Results  There were 40 study subjects, including 31 men and 9 women. The MDADI instrument adapted to Indonesian is valid and reliable as an instrument for assessing the quality of life of patients with head and neck cancer with swallowing disorders, with r-values ranging from 0.314 to 0.939. Internal consistency shows that Cronbach's α is 0.915, and test-retest reliability (intra-class correlation) ranges from 0.919 to 0.985.

Conclusion  The translation and validation of the Indonesian MDADI instrument were performed as an instrument for assessing the quality of life of head and neck cancer patients with swallowing disorders.

The PRO-ACTIVE trial protocol: a randomized study comparing the effectiveness of PROphylACTic swallow InterVEntion for patients receiving radiotherapy for head and neck cancer

BACKGROUND

Swallowing therapy is commonly provided as a treatment to lessen the risk or severity of dysphagia secondary to radiotherapy (RT) for head and neck cancer (HNC); however, best practice is not yet established. This trial will compare the effectiveness of prophylactic (high and low intensity) versus reactive interventions for swallowing in patients with HNC undergoing RT.

METHODS

This multi-site, international randomized clinical trial (RCT) will include 952 adult patients receiving radiotherapy for HNC and who are at high risk for post-RT dysphagia. Participants will be randomized to receive one of three interventions for swallowing during RT: RE-ACTIVE, started promptly if/when dysphagia is identified; PRO-ACTIVE EAT, low intensity prophylactic intervention started before RT commences; or, PRO-ACTIVE EAT+EXERCISE, high intensity prophylactic intervention also started before RT commences. We hypothesize that the PRO-ACTIVE therapies are more effective than late RE-ACTIVE therapy; and, that the more intensive PRO-ACTIVE (EAT + EXERCISE) is superior to the low intensive PRO-ACTIVE (EAT). The primary endpoint of effectiveness is duration of feeding tube dependency one year post radiation therapy, selected as a pragmatic outcome valued equally by diverse stakeholders (e.g., patients, caregivers and clinicians). Secondary outcomes will include objective measures of swallow physiology and function, pneumonia and weight loss, along with various patient-reported swallowing-related outcomes, such as quality of life, symptom burden, and self-efficacy.

DISCUSSION

Dysphagia is a common and potentially life-threatening chronic toxicity of radiotherapy, and a priority issue for HNC survivors. Yet, the optimal timing and intensity of swallowing therapy provided by a speech-language pathologist is not known. With no clearly preferred strategy, current practice is fraught with substantial variation. The pragmatic PRO-ACTIVE trial aims to specifically address the decisional dilemma of when swallowing therapy should begin (i.e., before or after a swallowing problem develops). The critical impact of this dilemma is heightened by the growing number of young HNC patients in healthcare systems that need to allocate resources most effectively. The results of the PRO-ACTIVE trial will address the global uncertainty regarding best practice for dysphagia management in HNC patients receiving radiotherapy.

TRIAL REGISTRATION

The protocol is registered with the US Patient Centered Outcomes Research Institute, and the PRO-ACTIVE trial was prospectively registered at ClinicalTrials.gov , under the identifier NCT03455608 ; First posted: Mar 6, 2018; Last verified: Jun 17, 2021. Protocol Version: 1.3 (January 27, 2020).

Pretreatment Adherence to a Priori-Defined Dietary Patterns Is Associated with Decreased Nutrition Impact Symptom Burden in Head and Neck Cancer Survivors

Dietary intake is understood to contribute to nutrition impact symptoms (NIS) in patients with head and neck squamous cell carcinoma (HNSCC). The purpose of this study was to evaluate the performance of four a priori-defined diet quality indices on the presence of NIS 1 year following diagnosis using data on 323 participants from the University of Michigan Head and Neck Specialized Program of Research Excellence (UM-SPORE). Pretreatment dietary intake was measured before treatment initiation using a food frequency questionnaire. NIS were measured along seven subdomains. Multivariable binary logistic regression models were constructed to evaluate relationships between pretreatment scores on a priori-defined diet quality indices (AHEI-2010, aMED, DASH, and a low-carbohydrate score) and the presence of individual symptoms in addition to a composite “symptom summary score” 1-year postdiagnosis. There were several significant associations between different indices and individual NIS. For the symptom summary score, there were significant inverse associations observed for aMED (OR_Q5-Q1: 0.36, 95% CI: 0.14–0.88, p_trend = 0.04) and DASH (OR_Q5-Q1: 0.38, 95% CI: 0.15–0.91, p_trend = 0.02) and the presence of NIS 1-year postdiagnosis. Higher adherence to the aMED and DASH diet quality indices before treatment may reduce NIS burden at 1-year postdiagnosis.

Validity and Reliability of an Arabic Version of MD Anderson Dysphagia Inventory (MDADI)

Dysphagia is a common adverse event among head and neck (H&N) cancer patients. We aimed, for the first time, to validate the Arabic version of the MD Anderson Dysphagia Inventory (MDADI) among 82 Saudi Arabian patients with H&N cancer. We followed established validation guidelines and translated the 20-item MDADI using the forward-backward method. Our results revealed 100% feasibility. Test-retest reliability demonstrated acceptable interclass correlation coefficients (ICC) for the subscale domains (emotional = 0.973, physical = 0.971, and functional = 0.956) and composite score (ICC = 0.984). The Cronbach's alpha coefficients for the emotional, functional, and physical subscales were 0.937, 0.825, and 0.945, respectively (composite score = 0.975). We confirmed concurrent validity by demonstrating significant correlations between the domains of the Arabic MDADI and European Organization for Research and Treatment of Cancer (EORTC) Quality-of-Life Head and Neck Module (QLQ-H&N35). Our study validated the Arabic version of the MDADI among H&N cancer patients from Saudi Arabia.

Level of Awareness, Knowledge, and Involvement of Malaysian Medical and Dental Practitioners in Dysphagia Management of Head and Neck Cancer Patients

Head and neck cancer patients are at high risk of developing dysphagia from undergoing cancer treatment. It is essential for medical and dental practitioners to recognize speech-language pathologists' role and dysphagia symptoms to provide a timely referral to speech-language pathologists. This study aims to determine the level of awareness, knowledge, and involvement of medical and dental practitioners in dysphagia management. A total of 391 medical and dental practitioners from 22 government hospitals across Malaysia participated in this cross-sectional study. Participants completed the questionnaire specifically on the level of involvement, knowledge, awareness regarding the role of SLP and dysphagia symptoms. The results revealed a statistically significant relationship between the level of awareness of the role of SLP, χ² (4, 391) = 9.87, p = 0.043 and the level of involvement of medical and dental practitioners, χ² (8, 391) = 27.68, p = 0.001 and percentage of referring head and neck cancer patients. The odds of referring head and neck cancer patients for pre-treatment assessment increased three times for each one unit of the participation of medical and dental practitioners [OR] 3.65 (1.56, 8.51) p = 0.003 among those who are already highly involved in dysphagia management. These findings compel healthcare practitioners in head and neck cancer to revisit their collaborative practices. Head and neck cancer patients should receive swallowing management from speech-language pathologists to improve their swallowing function and avoid further complications such as dehydration, malnutrition, and death.

Asymptomatic swallowing disorders may be present in individuals with laryngeal and hypopharyngeal cancer treated with chemo-radiotherapy

PURPOSE

Patients with advanced laryngeal and hypopharyngeal cancer are often treated with chemo-radiotherapy to avoid total laryngectomy. Subclinical swallowing disorders could be present in these patients even though patients do not complain of any symptoms. We sought to evaluate the impact of chemoradiation on swallowing and quality of life.

METHODS

We studied 21 patients undergoing chemo-radiotherapy for advanced laryngeal and hypopharyngeal cancer. All patients were tumor-free and none reported symptoms related to dysphagia during follow-up or showed altered routine screening tests (EAT-10) to detect it. Swallowing functions were assessed using volume-viscosity swallow test (V-VST) and fiberoptic endoscopic evaluation of swallowing (FEES). Quality of life was assessed with the EORT-H&N35, and SWAL-QOL scales.

RESULTS

Frequent alterations in swallowing efficacy (100%) and safety (85.5%) were detected with V-VST and FEES. Quality-of-life scales showed a reduction in their scores between 12 and 17%, mainly in the areas of symptoms.

CONCLUSION

Swallowing disorders are common after chemo-radiotherapy, even in patients who do not clinically manifest these disorders, contributing to a decrease in patients' quality of life. FEES and V-VST are useful procedures to detect asymptomatic swallowing disorders.

Functional results of swallowing and aspiration after oral cancer treatment and microvascular free flap reconstruction: A retrospective observational assessment

This study aimed to assess the functional swallowing outcomes in cohort of oral cancer patients treated with tumor resection and reconstruction by means of microvascular free flaps. Duration from onset to the last examination was classified into three periods: less than 12 months, from 13 to 24 months, and more than 24 months. Type of feeding, dysphagia, and laryngeal aspiration were the dependent variables, and the study was mainly focused on the data from the multivariate analysis. Fifty-one patients were included in the study. Twenty-one patients had dysphagia, 11 showed stasis in vallecula and pyriform sinuses, 9 experienced laryngeal penetration, and 8 aspirations. Surgery combined with radiochemotherapy was associated with a higher prevalence of dysphagia (p = 0.03). Frequency of dysphagia was higher in the first year after treatment and less frequent after 24 months (p = 0.003). Dysphagia was associated with laryngeal penetration (p = 0.001), and this with aspiration (p < 0.0005). In conclusion, as it seems that the method of reconstruction has a major influence on swallowing, when there are relevant alternatives in the way the reconstruction is done, always the approach should be chosen that reduces dysphagia to a minimum.

Determining the Impact of Thickened Liquids on Swallowing in Patients Undergoing Irradiation for Oropharynx Cancer

The current standard for the treatment of oropharynx cancers is radiation therapy. However, patients are frequently left with dysphagia characterized by penetration-aspiration (impaired safety) and residue (impaired efficiency). Although thickened liquids are commonly used to manage dysphagia, we lack evidence to guide the modification of liquids for clinical benefit in the head and neck cancer population. The objective of this study was to assess the impact of slightly and mildly thick liquids on penetration-aspiration and residue in 12 patients with oropharyngeal cancer who displayed penetration-aspiration on thin liquid within 3 to 6 months after completion of radiotherapy. Significantly fewer instances of penetration-aspiration were seen with slightly and mildly thick liquids as compared with thin (P < .05). No differences were found across stimuli in the frequency of residue. Patients with oropharyngeal cancers who present with post-radiation therapy dysphagia involving penetration-aspiration on thin liquids may benefit from slightly and mildly thick liquids without risk of worse residue.

Swallowing and communication outcomes following primary transoral robotic surgery

BACKGROUND

Heterogeneity within studies examining transoral robotic surgery (TORS) for oropharyngeal cancer (OPC) has made it challenging to make clear conclusions on functional outcomes. Infrequent use of instrumental swallow examinations compounds uncertainty surrounding the proposed functional advantage to TORS.

METHODS

A prospective cohort of 49 patients underwent speech and swallowing assessment 12 months following treatment for OPC. Patients were assessed using fibreoptic endoscopic evaluation of swallowing (FEES), clinician- and patient-reported outcomes. Participants were matched according to tumor site, T category, and age. Speech and swallowing outcomes were compared for those receiving TORS versus chemoradiation.

RESULTS

When adjuvant radiotherapy to the primary site could be avoided, TORS demonstrated an advantage for feeding tube duration, secretion severity, penetration/aspiration, M. D. Anderson Dysphagia Inventory (MDADI), and airway protection.

CONCLUSION

This explorative study suggests that a treatment philosophy of selecting patients for TORS where adjuvant therapy can be omitted or confined to the neck warrants further evaluation.

European white paper: oropharyngeal dysphagia in head and neck cancer

PURPOSE

To develop a European White Paper document on oropharyngeal dysphagia (OD) in head and neck cancer (HNC). There are wide variations in the management of OD associated with HNC across Europe.

METHODS

Experts in the management of specific aspects of OD in HNC across Europe were delegated by their professional medical and multidisciplinary societies to contribute to this document. Evidence is based on systematic reviews, consensus-based position statements, and expert opinion.

RESULTS

Twenty-four sections on HNC-specific OD topics.

CONCLUSION

This European White Paper summarizes current best practice on management of OD in HNC, providing recommendations to support patients and health professionals. The body of literature and its level of evidence on diagnostics and treatment for OD in HNC remain poor. This is in the context of an expected increase in the prevalence of OD due to HNC in the near future. Contributing factors to increased prevalence include aging of our European population (including HNC patients) and an increase in human papillomavirus (HPV) related cancer, despite the introduction of HPV vaccination in various countries. We recommend timely implementation of OD screening in HNC patients while emphasizing the need for robust scientific research on the treatment of OD in HNC. Meanwhile, its management remains a challenge for European professional associations and policymakers.

Seeding of Gastrostomy Tube Site in Patient With Squamous Cell Carcinoma of the Tongue: A Case Report

Enteral nutrition (EN) is a widely used therapeutic tool to provide nutrition support for patients with various clinical conditions, including different types of cancer. Head and neck cancers, often complicated by dysphagia, are among leading indications for enteral feeding. Percutaneous endoscopic gastrostomy (PEG) and percutaneous endoscopic jejunostomy (PEJ) tubes are typically used to deliver EN. This article presents a case report of a young male with squamous cell carcinoma of the tongue. Unfortunately, he developed metastasis of his cancer at the right lateral side of the PEG placement site, requiring surgical resection of seeded growth at the PEG site. This rare complication can be challenging, as it requires a high index of suspicion to diagnose and can potentially limit nutrition support options. A number of theories have been proposed to explain seeding during PEG/PEJ placement, including direct repositioning of malignant cells during instrumentation. A specific placement technique has not been shown to be superior, as seeding was reported with all placement techniques. However, given the lack of statistically powerful studies to describe this entity, there are still gaps we need to explore to better understand seeding of feeding tubes and best practices around diagnosis and early treatment. EN continues to be an important part of caring for patients with cancer during active or palliative treatments. Understanding potential risks in the setting of cancer metastasis is beneficial to the patients and multidisciplinary teams involved. Early recognition of possible seeding of feeding tube sites is necessary to ensure subsequent timely surgical intervention.

Swallowing exercises for head and neck cancer patients: A systematic review and meta-analysis of randomized control trials

BACKGROUND

Extensive surgery and chemo/radiation therapy (C/RT) to manage head and neck cancer (HNC) patients affects their ability to swallow food and liquids, risk of aspiration and greatly influences their quality of life (QOL).

OBJECTIVES

Ascertain the effectiveness of swallowing exercises on improving swallowing function, performance status, mouth opening, risk of aspiration/penetration and QOL in HNC patients.

DESIGN

Systematic review and meta-analysis of randomized controlled trials DATA SOURCES: PubMed, Ovid-Medline, Embase, Cochrane Library, CINAHL and Web of Science and included all available RCTs.

REVIEW METHODS

We followed the PRISMA guidelines and standard methods for conducting a systematic review and meta-analysis. Comprehensive Meta-analysis 3.0 using the random effects model was used for data analysis.

RESULTS

In total, 19 RCTs with 1100 participants were identified and included in the current review. Swallowing exercises had significant small effect on swallowing function 0.33 (95%CI = 0.00-0.65) and moderate effect on mouth opening 0.60 (95%CI = 0.21-0.99) immediately after intervention and small effect at 6-month follow-up 0.46 (95%CI = 0.11-0.81). However, non-significant effects were observed on risk of aspiration/penetration, performance status and all domains of QOL.

CONCLUSION

Swallowing exercises demonstrated effectiveness in improving swallowing function and mouth opening in HNC patients undergoing multimodal treatment. This is the first comprehensive systematic review and meta-analysis of RCTs to assess the effect of swallowing exercises in HNC patients undergoing multimodal treatment. Nurses can play an important role in assisting the delivery of oropharyngeal swallowing exercises including jaw exercises, tongue exercises and swallowing maneuvers with assistance and guidance from speech pathologists to help improve HNC complications and QOL for HNC survivors.

Results of pretreatment swallowing evaluation in patients with stage III/IV laryngeal and hypopharyngeal carcinoma

INTRODUCTION

Laryngeal and hypopharyngeal carcinoma are among the common head and neck cancers causing considerable swallowing dysfunction. The functional status of the organ (larynx) is an important point of contention while considering the patients for organ preservation protocol.

METHODOLOGY

The aim of this retrospective study was to assess the swallowing status in stage III/IV laryngeal and hypopharyngeal carcinoma and its influence on treatment decision. We evaluated all treatment naïve patients who were referred to the swallowing clinic in 2017 (Jan-Dec) for assessment of swallowing prior to treatment initiation.

RESULTS

One hundred patients satisfied the eligibility criteria and were included in the study. The site and stage of laryngeal and hypopharyngeal cancer cases were almost equal in number. Their median age was 58 years. Fiberoptic endoscopic evaluation of swallowing (FEES) was done in all patients. 30% of the patients only had swallowing difficulties. Only advanced T-stage (p = 0.04) had an influence on the pretreatment swallowing status. Thirty-seven patients required nasogastric tube (NGT) for feeding. By 2 month post-treatment completion, most patients on NGT could resume oral feeding.

CONCLUSIONS

Pretreatment swallowing assessment alone did not significantly seem to influence our decisions for organ preservation treatment. However, patients with aspiration could be identified and managed appropriately. Most patients on NGT could resume oral feeds post-treatment completion.

Head and neck cancer therapy-related oral manifestation management in the COVID-19 pandemic: a critical review

With the onset of the new coronavirus disease (COVID-19) pandemic, the dental treatment of patients at risk of infection has become quite challenging. In view of this, patients with head and neck cancer may present with oral complications due to anticancer therapy, making dental assistance necessary. Thus, the objective of the study was to review the literature and critically discuss important concerns about the treatment of patients with head and neck cancer during the COVID-19 pandemic. Because dental professionals are in close contact with the main viral transmission routes, this study presents recommendations for management and protection during clinical dental care. The main characteristics and transmission routes of COVID-19 are also discussed. Dental professionals should control pain and the side effects of antineoplastic treatment and use preventive measures for infection control. During this pandemic, patients with head and neck cancer should not undergo elective procedures, even if they do not have symptoms or a history of COVID-19; therefore, in asymptomatic or painless cases, only preventive actions are recommended. In symptomatic or painful cases, precautions for safe interventional treatments must be implemented by following the hygiene measures recommended by health agencies and using personal protective equipment. During health crises, new protocols emerge for cancer treatment, and professionals must act with greater attention toward biosafety and updated knowledge. It is important to offer adequate individualized treatment based on the recommendations of preventative and interventional treatments so that patients can face this difficult period with optimized quality of life.

Sarcopenia as an early complication of patients with head and neck cancer with dysphagia

OBJECTIVE

To evaluate the relationship between dysphagia and sarcopenia in patients with head and neck cancer (HNC).

METHODS

A cross-sectional, prospective study, sample by convenience, including men with HNC during their initial oncologic evaluation. Patients answered questionnaires (demographic data, lifestyle habits, disease characteristics and the Short International Physical Activity Questionnaire). Swallowing capacity, bioelectrical impedance (BIA), handgrip strength (HGS) and physical performance test (Timed Up and Go test) were evaluated. Sarcopenia was diagnosed following the European Working Group on Sarcopenia and Foundation for the National Institute of Health criterion.

RESULTS

71 men, elderly (66.9 ± 6.25 years) and adults (53.17 ± 3.66 years), were divided into the dysphagic group (DG, 44) and the non-dysphagic group (NDG, 27). The DG presented lower body mass index (BMI), lower skeletal muscle mass and a higher number of sarcopenic individuals than the NDG (p < 0.05). The degree of dysphagia was associated with weight loss (p = 0.006) but not with sarcopenia (p = 0.084) in the DG. The multivariate analysis showed that age, percentage of weight loss and BMI interfered with pre-sarcopenia, and only age influenced sarcopenia (p < 0.005).

CONCLUSION

Patients with dysphagia had a high prevalence of sarcopenia in the pre-treatment phase, related to age.

MRI- and CT-determined changes of dysphagia / aspiration-related structures (DARS) during and after radiotherapy

Purpose

The concept of dysphagia/aspiration-related structures (DARS) was developed against the background of severe late side effects of radiotherapy (RT) for head and neck cancer (HNC). DARS can be delineated on CT scans, but with a better morphological discrimination on magnetic resonance imaging (MRI). Swallowing function was analyzed by use of patient charts and prospective investigations and questionnaires.

Method

Seventeen HNC patients treated with intensity-modulated radiotherapy (IMRT) ± chemotherapy between 5/2012 – 8/2015 were included. Planning CT (computed tomography) scans and MRIs (magnetic resonance imaging) prior, during 40 Gray (Gy) radiotherapy and posttreatment were available and co-registered to delineate DARS. The RT dose of each DARS was calculated. Five patients were investigated posttreatment for swallowing function and assessed by means of various questionnaires for quality of life (QoL), swallowing, and voice function.

Results

By retrospective comparison of DARS volume, a significant change in four of eight DARS was detected over time. Three increased and one diminished. The risk of posttreatment dysphagia rose by every 1Gy above the mean dose (D mean) of RT to DARS. 7.5 was the risk factor for dysphagia in the first 6 months, reducing to 4.7 for months 6-12 posttreatment. For all five patients of the prospective part of swallowing investigations, a function disturbance was detected. These results were in contrast to the self-assessment of patients by questionnaires. There was neither a dose dependency of D mean DARS volume changes over time nor of dysphonia and no correlation between volume changes, dysphagia or dysphonia.

Conclusion

Delineation of DARS on MRI co-registered to planning CT gave the opportunity to differentiate morphology better than by CT alone. Due to the small number of patients with complete MRI scans over time, we failed to detect a dose dependency of DARS and swallowing and voice disorder posttreatment.

Toxicity syndrome and early competing deaths in head-and-neck cancer undergoing radiation therapy: Observation and hypothesis

Radiotherapy (RT) and/or concurrent chemoradiation (CRT) is the mainstay for the treatment of locally advanced head-and-neck cancer (LAHNC). Sepsis remains a poorly understood and unrecognized event in head-and-neck cancer. The study aims to hypothesize a 'toxicity syndrome' leading to sepsis and subsequent sepsis-related deaths. A retrospective audit of all 125 LAHNC patients treated radically from January 2013 to June 2017 was conducted. A total of fifteen toxic deaths were reported. Thirteen deaths were attributed to sepsis. Individual toxicity for death was ascertained only for three cases. A toxicity syndrome namely 'mucositis-dysphagia-aspiration-sepsis (MDAS) complex' was proposed as the cause of death in the rest ten cases. The authors recommend the surveillance of the 'MDAS complex' for the prevention of early toxicity-related deaths in patients with LAHNC undergoing RT or CRT.
