Long-term prevalence of oropharyngeal dysphagia in head and neck cancer patients: Impact on quality of life

Swallowing Function Outcomes in Head and Neck Cancer Survivors Followed by a Long-Term Dysphagia Surveillance Protocol

BACKGROUND

This study aimed to evaluate swallow outcomes in head and neck cancer (HNC) survivors enrolled in a long-term dysphagia surveillance protocol following curative intent radiotherapy (RT).

METHODS

We conducted a retrospective review of videofluoroscopic swallow studies from 2015 to 2023 in HNC patients treated with RT. Swallow kinematics and function were assessed at baseline, 0-1, 1-2, 2-5, and 5+ years post-RT. Logistic regression models assessed kinematic deviations beyond 2SD from normative and dichotomized outcomes.

RESULTS

Among 638 patients with 1167 VFSS, 14.6% were 2 years post-RT, primarily oral cavity (29.6%) and oropharyngeal (46.7%) cancers treated with adjuvant (chemo) RT (53.3%). At 2 years, 51.3% exhibited abnormal hyolaryngeal movement, 27.5% had pharyngeal contraction abnormalities, and 9.0% had impaired pharyngoesophageal opening. Unsafe swallow was seen in 51.6% with moderate-to-profound dysphagia in 45%.

CONCLUSION

Dysphagia surveillance revealed significant swallowing impairments in HNC survivors, with unsafe swallowing prevalent in over half of cases 2 years post-RT.

Surgeon Perspectives on Addressing Mental Health Among Total Laryngectomy Patients

OBJECTIVE

Head and neck cancer patients, particularly those undergoing total laryngectomy, exhibit high rates of depression and suicide, even compared to other cancer patients. Thus, this study seeks to understand head and neck surgeons' perceived roles in and treatment patterns regarding mental health sequelae among total laryngectomy patients.

METHODS

An anonymous survey regarding provider perspectives about the mental health experiences of total laryngectomy patients was designed and distributed via email to American Head and Neck Society members and academic otolaryngology head and neck surgery departments. Descriptive statistics were utilized to describe results.

RESULTS

Respondents (n = 63) reported frequently seeing mental health issues among total laryngectomy patients (on average, 48% of patients) and believed otolaryngologists should frequently screen for these conditions (85%). However, a significant subset of the sample (39%) reported feeling uncomfortable addressing mental health issues and cited factors such as lack of expertise (73%) or lack of resources to address mental health (73%). Overall, most respondents agreed that this population could receive better mental healthcare (88%). Referral to speech-language pathologists (80%), community-based support groups (54%), and referral to a mental health provider (n = 35, 54%) were frequently recommended post-operative prophylactic measures.

CONCLUSION

This national cross-sectional survey of head and neck surgeons demonstrated that while physicians acknowledge and appreciate the need for mental health services among laryngectomy patients, a significant minority feel unprepared to address mental health due to a lack of training and resources. Additional research is needed to identify methods to effectively address this gap in care for laryngectomy patients.

Clinical aspects of oral cancer and potentially malignant disorders in South and Southeast Asia

BACKGROUND

Oral cancer and Oral Potentially Malignant Disorders (OPMD) are major health problems in South and Southeast Asia.

AIMS

To describe and discuss the clinical aspects of Oral Cancer and OPMD in South and Southeast Asia.

MATERIALS AND METHODS

Literature review of concepts and data over the last four decades.

DISCUSSION

Asian countries account for about two-thirds of new cases of oral cancer (OC) globally, with the highest burden in the South and Southeast Asian countries, including Pakistan and India. Habits, dietary patterns, socioeconomic status, and access to routine dental care play a crucial role in defining the demographics and clinical presentation of OC in these regions and significantly influence the morbidity and mortality of the disease. This region sees the use of different types of tobacco with or without areca nut (AN), such as pan masala, gutka, gul, snuff, mawa, and mishri. Tobacco use is high among men in Sri Lanka, Myanmar, Maldives, Bangladesh, Nepal, India and Bhutan. Areca nut is the fourth most common addictive substance globally and is frequently used in South and Southeast Asian countries, including Southeast China, Hainan Island, India, Taiwan, and the Pacific Islands, and immigrants from these regions in Africa, Europe, and North America. The use of these products results in mucosal alterations with varied clinical presentation of Oral Potentially Malignant Disorders (OPMDs) and OC. We discuss here the different types of OPMD and OC, the diagnostic aids and their relevance in clinical practice, and factors that influence their prognosis.

Novel Survivorship Paradigms in Head/Neck Cancer

Long-term care for head and neck cancer (HNC) survivors is complex. Despite an improvement in survival and the evolution of treatment paradigms (de-escalation, targeted therapy), notably in the context of human papillomavirus (HPV)-related oropharyngeal cancers, HNC survivors still experience a wide range of side effects and needs, which impact their functionality, quality of life, survival and require concerted, coordinated survivorship care. In this review, we perform an overview of existing HNC survivorship recommendations within the context of novel evidence, our current understanding of survivorship care, and incorporate them into the Nekhluydov Survivorship Care Framework. This framework provides a novel way to appreciate and comprehensively address all aspects of HNC survivorship care. Further research is crucial to develop evidence-based, patient-centered personalized approaches to survivorship care in different HNC populations and understand barriers to successful implementation.

The Impact of Home Enteral Tube-Feeding on the Intent and Experience of Going Out in Public: A Qualitative Study on Patients' and Caregivers' Perspectives

BACKGROUND

Individuals on tube-feeding experience significant lifestyle changes and social isolation, but the barriers and support for travelling out while on tube-feeding to reintegrate into the community have not been studied. This research explores the factors influencing the decisions of individuals on tube-feeding and their carers to travel outside of their homes, their experiences, and perceived barriers and support when performing tube-feeding in public settings.

METHODS

A qualitative design using purposive sampling explored the experiences of three individuals and five carers living at home on long-term tube-feeding. One-to-one semi-structured interviews were conducted and transcribed. Thematic analysis was conducted via open coding and merging of recurring codes to form themes.

RESULTS

Six themes emerged: (1) Motivators and deterrents to going out: Motivators include desire for social normalcy. Deterrents include physical health, logistics and psychosocial considerations, such as fear of negative public perception and the loss of travelling and dining as motivating social activities. (2) Going out requires meticulous preparation and planning. (3) Inadequate tube-feeding facilities in the community contribute to ambivalence and discomfort to tube-feeding outside. Participants must accept potential negative emotions when confronted with public reaction to tube-feeding. (4) Ideal tube-feeding facilities should be private and hygienic, in highly frequented locations. (5) Community support and awareness are needed to support tube-feeding. (6) Adaptability is crucial when satisfactory feeding locations are absent during local and overseas travel.

CONCLUSIONS

Carers and healthcare professionals are pivotal in encouraging patients to disregard public curiosity, planning tube-feeding logistics, and advocating for the right to tube feed in public spaces without shame. Public awareness, carer support, and availability of tube-feeding facilities should be improved for patients to live, work and engage meaningfully in the community.

Quality of life outcomes in patients receiving dental implants in vascularised bone flaps for mandibular reconstruction

Resection, reconstruction, and rehabilitation of the mandible impact function and health related quality of life (HRQOL). In this study, we aimed to understand the impact of delayed versus immediate dental implant placement. A cross-sectional and prospective study was conducted including patients who underwent reconstruction of the mandible via osseous vascularised bone flaps and dental implants. The FACE-Q Head and Neck Cancer module and the MD Anderson Dysphagia Inventory and Speech Handicap Index were used to evaluate HRQOL. A total of 187 implants were placed in 52 patients, of which 44 patients (85%) completed questionnaires. Immediate dental implant placement was associated with superior FACE-Q appearance (p = 0.02), oral competence (p = 0.004), smile distress (p = 0.03), and satisfaction with information (p = 0.004). Dentoalveolar rehabilitation through the placement of immediate dental implants at the time of surgery was found to be associated with higher HRQOL scores related to appearance, eating and drinking, oral competence, and smile.

Health-related quality of life assessment in head and neck cancer: A systematic review of phase II and III clinical trials

Background

Patients with head and neck cancer (HNC) bear a significant load, due to both disease-related symptoms and to toxicities associated with treatments. Evaluating quality of life (QoL) is crucial to gauge the physical and psychological impact on these patients. Our primary aim was to assess whether QoL has been incorporated as an endpoint in phase II and III clinical trials for HNC patients in the last 15 years.

Material and methods

We investigated publications from 11 major journals to identify randomized and non-randomized phase II and phase III clinical trials assessing locoregional and systemic treatments as either single or multimodal strategies, published from 2008 to March 2023 in patients with HNC.

Results

We screened 2045 studies and we selected 158 articles that met the eligibility criteria including a total of 31.734 patients. Globally, QoL was the primary end point in 2 publications (1 %), secondary in 38 (24 %), and exploratory in 7 (4 %). The quota of primary publications with QoL among endpoints increased over time: 14 (17 %) publications between 2008 and 2015 and 33 (42 %) between 2016 and 2023. Notably, in phase III trials, QoL was included among endpoints in 30 (49 %) publications, whereas in phase II studies, QoL was present in 17 (17 %).

Conclusions

In HNC, the assessment of QoL as an endpoint in clinical trials is still missing, even in phase III trials. Efforts should be focused on the adoption of Patient-Reported Outcomes (PROs) in trials to improve the definition of treatment value in this vulnerable population.

Characterizing Physiologic Swallowing Impairment Profiles: A Large-Scale Exploratory Study of Head and Neck Cancer, Stroke, Chronic Obstructive Pulmonary Disease, Dementia, and Parkinson's Disease

PURPOSE

The purpose of the present study was to use a large swallowing database to explore and compare the swallow-physiology impairment profiles of five dysphagia-associated diagnoses: chronic obstructive pulmonary disease (COPD), dementia, head and neck cancer (HNC), Parkinson's disease (PD), and stroke.

METHOD

A total of 8,190 patients across five diagnoses were extracted from a de-identified swallowing database, that is, the Modified Barium Swallow Impairment Profile Swallowing Data Registry, for the present exploratory cross-sectional analysis. To identify the impairment profiles of the five diagnoses, we fit 18 partial proportional odds models, one for each of the 17 Modified Barium Swallow Impairment Profile components and the Penetration-Aspiration Scale, with impairment score as the dependent variable and diagnoses, age, sex, and race as the independent variables with interactions between age and diagnoses and between PD and dementia (in effect creating a PD with dementia [PDwDem] group). For components with > 5% missingness, we applied inverse probability weighting to correct for bias.

RESULTS

PD and COPD did not significantly differ on 13 of the 18 outcome variables (all ps > .02). Dementia, stroke, and PDwDem all showed worse impairments than COPD or PD on five of six oral components (all ps < .007). HNC had worse impairment than all diagnoses except PDwDem for nine of 10 pharyngeal components (all ps < .006). Stroke and HNC had worse penetration/aspiration than all other diagnoses (all ps < .003).

CONCLUSIONS

The present results show that there are both common and differing impairment profiles among these five diagnoses. These commonalities and differences in profiles provide a basis for the generation of hypotheses about the nature and severity of dysphagia in these populations. These results are also likely highly generalizable given the size and representativeness of the data set.

IGSF3 tissue expression in squamous cell carcinoma of the oropharynx: a novel tool for prognosis assessment in HPV-related and HPV-unrelated disease

Biomarkers are not broadly used in the management of head and neck cancers (HNCs). Biomarkers have been beneficial in the management of other cancers, however, not in HNCs. Therefore, we observed the immunopositivity of a novel biomarker called immunoglobulin superfamily member 3 (IGSF3) in tumor tissues in HPV-related and HPV-unrelated OPSCC. Two patient cohorts (C1 and C2) from separate time periods were available for this study (total N = 282). Both consisted of OPSCC patients treated at the Helsinki University Hospital (HUS, Helsinki, Finland) during 2000-2016. For HPV determination, HPV mRNA in situ hybridization was used. Immunohistochemistry was used to assess IGSF3 immunopositivity in cancer tissues. Overall survival (OS) was used as endpoint in the statistical analysis. In C1, stronger immunopositivity of IGSF3 in tumor-infiltrating lymphocytes (TILs) correlated with favorable OS (p = 0.005). Stronger IGSF3 immunopositivity in tumor cells (TCs) was associated with HPV negativity (p = 0.017). Stronger IGSF3 immunopositivity in TILs correlated with HPV positivity (p < 0.001). Elevated IGSF3 immunopositivity in TILs associates with HPV-related tumors and may signify favorable prognosis. The immunopositivity of IGSF3 differs between HPV-related and HPV-unrelated OPSCC.

MiR-22-3p as a promising predictor of nutritional deficiencies in patients with head and neck cancer subjected to intensity-modulated radiation therapy

Head and neck cancer (HNC) is the seventh most common cancer globally, with 20-60% of patients experiencing nutritional deficiencies. Recent studies indicate that microRNAs (miRNAs) may serve as molecular markers for malnutrition. This study evaluated miR-22-3p as a potential predictor of nutritional deficiencies and a prognostic factor in HNC patients undergoing intensity-modulated radiation therapy (IMRT). From 2014 to 2017, fifty-six advanced HNC patients at the Medical University of Lublin received IMRT, with miR-22-3p levels measured from peripheral blood before treatment. Statistical analysis using MedCalc 15.8 revealed that underweight patients had significantly lower miR-22-3p expression compared to non-underweight patients (0.89 vs. 2.47; p = 0.0233). Moderately or severely malnourished patients also showed reduced miR-22-3p levels compared to well-nourished individuals (1.42 vs. 11.04; p = 0.026). Additionally, patients with critical weight loss (CWL) had significantly lower miR-22-3p levels than those without CWL (0.96 vs. 4.91; p = 0.0015). Weak correlations were found between miR-22-3p levels, cancer stage, body mass index (BMI), and C-reactive protein (CRP), with lower miR-22-3p levels linked to advanced tumor stages and higher CRP levels. This study suggests miR-22-3p as a biomarker for nutritional deficiency risk in HNC patients, though further research is needed to validate its predictive capacity.

Swallowing outcomes after transoral robotic surgery and adjuvant treatment in unknown primary

OBJECTIVES

Robotic transoral mucosectomy of the base of tongue was introduced as a diagnostic procedure in patients treated for head and neck cancer with unknown primary (CUP), increasing the identification rate of the primary tumour. For the treatment of CUP, a considerable percentage of patients require adjuvant (chemo)radiation. The aim of this study was to investigate swallowing outcomes among CUP patients after TORS and adjuvant treatment.

SUBJECTS AND METHODS

A systematic review was carried out on studies investigating the impact of TORS and adjuvant treatment on swallowing-related outcomes among CUP patients In addition, a cross-sectional study was carried out on swallowing problems (measured using the SWAL-QOL questionnaire) among CUP patients in routine care who visited the outpatient clinic 1-5 years after TORS and adjuvant treatment.

RESULTS

The systematic review (6 studies; n = 98) showed that most patients returned to a full oral diet. The cross-sectional study (n = 12) showed that all patients were able to return to a full oral diet, nevertheless, 50% reported swallowing problems in daily life (SWAL-QOL total score ≥14).

CONCLUSION

Although after TORS and adjuvant treatment for CUP a full oral diet can be resumed, patients still experience problems with eating and drinking in daily life.

The Role of Oral Nutritional Supplements in Head and Neck Cancer Patients Undergoing Chemoradiotherapy

PURPOSE

This study aimed to assess the impact of oral nutritional supplements (ONS) on nutritional intake, body weight, and body composition in head and neck cancer (HNC) patients undergoing chemoradiotherapy. The study evaluated whether ONS could prevent treatment-related nutritional deterioration.

METHODS

This prospective observational pilot study included 30 HNC patients randomized into two groups: ONS (n = 15) and No ONS (n = 15). All participants underwent chemoradiotherapy, with the ONS group receiving 200 mL of a high-calorie, high-protein supplement twice daily. Nutritional status, including body weight, BMI, fat mass, fat-free mass, and bone mass, was assessed at three time points: baseline, mid-treatment, and end of treatment. Data were analyzed using the Mann-Whitney U test, with a p-value of ≤0.05 considered statistically significant.

RESULTS

At baseline, there were no significant differences between the two groups in body weight, BMI, or body composition. By the end of radiotherapy, the No ONS group showed significant reductions in body weight (p < 0.001), BMI (p < 0.001), fat mass (p < 0.001), and fat-free mass (p < 0.001), while the ONS group maintained more stable nutritional parameters. Acute radiotherapy toxicities, including nausea, dysphagia, and oral mucositis, were not significantly different between the two groups.

CONCLUSION

ONS effectively mitigates weight loss and preserves body composition in HNC patients undergoing chemoradiotherapy. While no significant reduction in radiation-induced toxicities was observed, the nutritional benefits of ONS support its use in preventing malnutrition in this patient population. Larger studies are needed to further validate these findings.

Estimating the Incidence and Prevalence of Dysphagia in New Zealand

Dysphagia imposes a substantial economic burden on global healthcare systems due to its pervasive, high-cost nature. To comprehend this burden, we must first assess dysphagia's prevalence and incidence in the general population. Existing studies on dysphagia prevalence encompass minor symptoms, while it is the severe cases that drive significant healthcare costs. We address this knowledge gap by estimating dysphagia incidence and prevalence in the New Zealand population, projecting future demographics of affected individuals. Incidence and prevalence rates of dysphagia within specific underlying medical conditions are sourced from existing literature. Median projected population estimates from Statistics New Zealand, by age, sex, and ethnicity are used to calculate dysphagia projections. Where possible, projections by age and ethnicity are provided until 2038 and projections by age and sex until 2073. In 2020, 9300 New Zealanders are estimated to have newly developed dysphagia while 1.5% of the general New Zealand population are estimated to have been living with the effects of the condition. By 2073, the number of individuals newly diagnosed annually is projected to increase to 24,500 and the prevalence of dysphagia is projected to increase to 2.6%. These results indicate that a significant number of New Zealanders are impacted by dysphagia. This number is predicted to dramatically increase in the future, mostly due to population ageing, indicating an increased burden on society and healthcare systems. Our work provides a useful starting point for countries worldwide to assess future healthcare resource demands associated with dysphagia, assisting with healthcare provision planning.

Possible sarcopenia and its association with hospital-associated dysphagia and decline in physical function: Findings from a heart failure patients prospective cohort study

BACKGROUND & AIMS

There is limited evidence regarding the association of sarcopenia with dysphagia and physical function in patients with heart failure. This study examined the association between possible sarcopenia and both swallowing and physical function in individuals with acute heart failure (AHF).

METHODS

This prospective cohort study included hospitalized patients with AHF. Possible sarcopenia was assessed on admission using calf circumference and grip strength according to an international diagnostic criteria. The primary outcome was dysphagia at discharge using the Food Intake Level Scale (FILS), and the secondary outcome was physical function at discharge using the Barthel Index (BI). Multiple regression analysis and logistic regression, adjusted for potential confounders, were used to examine the association between possible sarcopenia at admission and FILS and BI at discharge.

RESULTS

A total of 320 patients (mean age 81.5 years; 170 women) were included in the analysis; 199 (59.4%) were diagnosed with possible sarcopenia. Multivariate analysis showed that possible sarcopenia at admission was significantly associated with FILS at discharge (β = -0.1204; p = 0.039). Possible sarcopenia at admission was not significantly associated with BI at discharge (OR = 2.066; 95% CI, 0.910-4.692, p = 0.083).

CONCLUSIONS

Possible sarcopenia was associated with decline in swallowing function during hospitalization in patients with AHF. These findings highlight the need for early detection and treatment of possible sarcopenia in this setting.

Systematic review of adherence to swallow and trismus exercises during radiation therapy for head and neck cancer

Understanding the barriers and facilitators for prophylactic swallowing and trismus exercises for patients undergoing radiation to the head and neck may help exercise adherence. The analysis reviews all published reports of exercise adherence with a critical appraisal following PRISMA guidelines. A total of 137 potential papers were identified; 20 studies met the inclusion criteria. The most commonly reported facilitators for swallowing and trismus exercises were regular clinician contact and online resources to reinforce instructions, set goals, and manage radiation toxicities. Social support and perceived benefit from exercises were also reported to be of help. The most common barriers to exercise were radiation toxicities, anxiety, feeling overwhelmed with information, and not understanding the reason for the exercises. Understanding facilitators and barriers to adherence is critical when designing exercise interventions for patients undergoing radiation for head and neck cancer.

Immunomodulatory extracellular matrix hydrogel induces tissue regeneration in a model of partial glossectomy

While oropharyngeal cancer treatment regimens, including surgical resection, irradiation, and chemotherapy, are effective at removing tumors, they lead to muscle atrophy, denervation, and fibrosis, contributing to the pathogenesis of oropharyngeal dysphagia - difficulty swallowing. Current standard of care of rehabilitative tongue strengthening and swallowing exercises is ineffective. Here, we evaluate an alternative approach utilizing an acellular and injectable biomaterial to preserve muscle content and reduce fibrosis of the tongue after injury. Skeletal muscle extracellular matrix (SKM) hydrogel is fabricated from decellularized porcine skeletal muscle tissue. A partial glossectomy injury in the rat is used to induce tongue fibrosis, and SKM hydrogels along with saline controls are injected into the site of scarring two weeks after injury. Tissues are harvested at 3 and 7 days post-injection for gene expression and immunohistochemical analyses, and at 4 weeks post-injection to evaluate histomorphological properties. SKM hydrogel reduces scar formation and improves muscle regeneration at the site of injury compared to saline. SKM additionally modulates the immune response towards an anti-inflammatory phenotype. This study demonstrates the immunomodulatory and tissue-regenerative capacity of an acellular and minimally invasive ECM hydrogel in a rodent model of tongue injury.

Clinical reasoning during dysphagia assessment and management in acute care: A longitudinal qualitative study

BACKGROUND

Competent clinical reasoning forms the foundation for effective and efficient clinical swallowing examination (CSE) and consequent dysphagia management decisions. While the nature of initial CSEs has been evaluated, it remains unclear how new information gathered by speech-language therapists (SLTs) throughout a patient's acute-care journey is integrated into their initial clinical reasoning and management processes and used to review and revise initial management recommendations.

AIMS

To understand how SLTs' clinical reasoning and decision-making regarding dysphagia assessment and management evolve as patients transition through acute hospital care from referral to discharge.

METHODS & PROCEDURES

A longitudinal, qualitative approach was employed to gather information from two SLTs who managed six patients at a metropolitan acute-care hospital. A retrospective 'think-aloud' protocol was utilized to prompt SLTs regarding their clinical reasoning and decision-making processes during initial and subsequent CSEs and patient interactions. Three types of concept maps were created based on these interviews: a descriptive concept map, a reasoning map and a hypothesis map. All concept maps were evaluated regarding their overall structure, facts gathered, types of reasoning engaged in (inductive versus deductive), types of hypotheses generated, and the diagnosis and management recommendations made following initial CSE and during subsequent dysphagia management.

OUTCOMES & RESULTS

Initial CSEs involved a rich process of fact-gathering, that was predominantly led by inductive reasoning (hypothesis generation) and some application of deductive reasoning (hypothesis testing), with the primary aims of determining the presence of dysphagia and identifying the safest diet and fluid recommendations. During follow-up assessments, SLTs engaged in increasingly more deductive testing of initial hypotheses, including fact-gathering aimed at determining the tolerance of current diet and fluid recommendations or the suitability for diet and/or fluid upgrade and less inductive reasoning. Consistent with this aim, SLTs' hypotheses were focused primarily on airway protection and medical status during the follow-up phase. Overall, both initial and follow-up swallowing assessments were targeted primarily at identifying suitable management recommendations, and less so on identifying and formulating diagnoses. None of the patients presented with adverse respiratory and/or swallowing outcomes during admission and following discharge from speech pathology.

CONCLUSIONS & IMPLICATIONS

Swallowing assessment and management across the acute-care journey was observed as a high-quality, patient-centred process characterized by iterative cycles of inductive and deductive reasoning. This approach appears to maximize efficiency without compromising the quality of care. The outcomes of this research encourage further investigation and translation to tertiary and post-professional education contexts as a clear understanding of the processes involved in reaching diagnoses and management recommendations can inform career-long refinement of clinical skills.

WHAT THIS PAPER ADDS

What is already known on the subject SLTs' clinical reasoning processes during initial CSE employ iterative cycles of inductive and deductive reasoning, reflecting a patient-centred assessment process. To date it is unknown how SLTs engage in clinical reasoning during follow-up assessments of swallowing function, how they assess the appropriateness of initial management recommendations and how this relates to patient outcomes. What this paper adds to the existing knowledge Our longitudinal evaluation of clinical reasoning and decision-making patterns related to swallowing management in acute care demonstrated that SLTs tailored their processes to each patient's presentation. There was an emphasis on monitoring the suitability of the initial management recommendations and the potential for upgrade of diet or compensatory swallowing strategies. The iterative cycles of inductive and deductive reasoning reflect efficient decision-making processes that maintain high-quality clinical care within the acute environment. What are the potential or actual clinical implications of this work? Employing efficient and high-quality clinical reasoning is a hallmark of good dysphagia practice in maximizing positive patient outcomes. Developing approaches to understanding and making explicit clinical reasoning processes of experienced clinicians may assist SLTs of all developmental stages to provide high standards of care.

Comparing Homogenized Instantaneous Meals and Traditional Pureed Foods in Patients Affected by Dysphagia: A Pilot Study

Background: Institutionalized individuals with dysphagia are particularly at risk for malnutrition. This study investigated two texture-modified models for patients with dysphagia, as follows: (i) traditional homemade pureed food (PF) and (ii) homogenized meals obtained from dehydrated and rehydrated instantaneous preparations (IPs). Methods: A retrospective pilot study was performed. It included patients affected by medium-severity dysphagia admitted to the nursing home "Sacra Famiglia" Institute of Cocquio Trevisago, Varese. The patients were aged 41-81 years old and all had complex disabilities. They underwent anthropometric and biochemical parameter assessments at baseline, as well as at two months and four months follow-up. Results: The study involved 30 patients, 15 received the IP meal. The comparison between the baseline and the follow-up did not show significant anthropometric and biochemical parameter differences. Conversely, the IP group reported significantly higher levels of consumption and satisfaction, evaluated using a modified Chernoff scale based on three levels of smiles, than the PF group. Conclusions: The present findings provide promising indications to improve the diet of patients affected by dysphagia, since meal satisfaction is a relevant factor that has been shown to be associated with better patient mood, motivation to eat, and adherence to prescribed diet.

Conceptualizing Adult Dysphagia in the United States Within the International Classification of Functioning, Disability and Health (ICF)

Despite the well-documented safety concerns and effect on quality of life, there does not yet exist a wide-reaching framework that links the etiologies of swallowing disorders to the potential short- and long-term outcomes in the context of International Classification of Functioning, Disability and Health (ICF). This paper introduces an expert-reviewed conceptual framework to highlight common etiologies of dysphagia as well as integrate immediate outcomes of dysphagia with long-term outcomes of dysphagia in terms of medical problems, health-related quality of life, functional effect, and psychosocial features. It also outlines the potential cyclical nature of long-term dysphagia outcomes perpetuating the original dysphagia. This framework serves to inform clinicians of important dysphagic outcomes and to bring awareness to long-term outcomes that should be monitored by health care professionals, caregivers, or people with dysphagia.

Patient-reported outcome measures for dysphagia in head and neck cancer: A systematic review and appraisal of content validity and internal structure

Dysphagia is a major head and neck cancer (HNC) issue. Dysphagia-related patient-reported outcome measures (PROMs) are critical for patient-centred assessment and intervention tailoring. This systematic review aimed to derive a comprehensive inventory of HNC dysphagia PROMs and appraise their content validity and internal structure. Six electronic databases were searched to February 2023 for studies detailing PROM content validity or internal structure. Eligible PROMs were those developed or validated for HNC, with ≥20% of items related to swallowing. Two independent raters screened citations and full-text articles. Critical appraisal followed COSMIN guidelines. Overall, 114 studies were included, yielding 39 PROMs (17 dysphagia-specific and 22 generic). Of included studies, 33 addressed PROM content validity and 78 internal structure. Of all PROMs, only the SOAL met COSMIN standards for both sufficient content validity and internal structure. Notably, the development of 18 PROMs predated the publication of COSMIN standards. In conclusion, this review identified 39 PROMs addressing dysphagia in HNC, of which only one met COSMIN quality criteria. Given that half of PROMs were developed prior to COSMIN guidelines, future application of current standards is needed to establish their psychometric quality.

Pretreatment fat-free mass index correlates with early death in patients with head and neck squamous cell carcinoma

BACKGROUND

A significant proportion of patients with head and neck squamous cell carcinoma (HNSCC) are malnourished at diagnosis. In this study, we investigated how pretreatment body mass index (BMI) and fat-free mass index (FFMI) correlate with early death, and whether these measurements are useful markers of prognosis for risk stratification of head and neck cancer patients.

METHODS

Patients (n = 404) with newly diagnosed, curable HNSCC and WHO performance status 0-2 were prospectively included and met with a study representative before treatment initiation, as well as up to four follow-up visits. All patients provided an estimate of body weight at 6 months prior to diagnosis. Bioelectrical impedance analysis (BIA) was performed for all patients before treatment initiation.

RESULTS

Most patients had oropharyngeal (46%), oral cavity (28%), or laryngeal cancer (12%). Forty-five (11%) patients met the standardized criteria for malnutrition according to the Global Leadership Initiative on Malnutrition (GLIM) at diagnosis. FFMI at diagnosis was lower in patients who died within 6 and 12 months after the start of treatment than in patients who survived these time points (p = 0.035 and p = 0.005, respectively).

CONCLUSIONS

In this study, pretreatment FFMI was an independent prognostic factor for death within 6 and 12 months after the start of treatment in patients with HNSCC. Pretreatment BMI was not an independent risk factor for death within 6 and 12 months after treatment termination. Thus, FFMI may be useful for risk stratification of patients with head and neck cancer.

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.

Effect of topical steroid on soft tissue swelling following anterior cervical discectomy and fusion

Background

Anterior cervical discectomy and fusion is the most commonly used surgical approach for treating cervical spine conditions, but it can often lead to postoperative swallowing difficulties. To retrospectively assess the effects of topical triamcinolone acetonide in the anterior cervical surgery on swallowing function.

Methods

In this study, a retrospective design was used to select patients aged 18 years and older who were diagnosed with cervical spondylosis and required anterior cervical discectomy and fusion. Among them, the patients in the experimental group used triamcinolone acetonide topically in front of the plate during surgery, and the control group was the patients who did not use triamcinolone acetonide. The sex, age, operation time, operation segment, and preoperative soft tissue area were compared between the two groups.

Results

There were no significant differences in gender, age, operation time, and segment between the two groups. For the preoperative soft tissue area, triamcinolone acetonide was significantly lower than in the control group (P < 0.05).

Conclusion

The retrospective results of this study support that topical triamcinolone acetonide as a treatment in anterior cervical surgery can significantly reduce soft tissue swelling, and no effect was found on the operation time, postoperative blood loss, and segment. These findings provide an important basis for clinical care teams to make treatment decisions and confirm the effectiveness of triamcinolone acetonide in improving swallowing function. However, there was a possibility of information collection and selection bias due to the limitations of retrospective studies. To confirm and further advance the use of this treatment, more rigorous prospective randomized controlled trials are recommended to validate these preliminary results.

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.

Predictors of Swallowing-Related Quality of Life in United States Veterans with Dysphagia

While both dysphagia and poor health-related quality of life frequently occur in United States (US) Veterans, swallowing-related quality of life in this population has not been systematically examined. This retrospective clinical observation study aimed to determine the independent predictors of swallowing-related quality of life for a sample of US Veterans. We examined the following variables in a multivariate analysis to determine the predictors of Swallowing Quality of Life Questionnaire scores: demographic information, Modified Barium Swallow Impairment Profile (MBSImP) scores, Penetration-Aspiration Scale scores, anterior lingual pressures, and Functional Oral Intake Scale scores. MBSImP oral phase score was the only variable that reached statistical significance (p ≤ 0.01), demonstrating that a more severe physiologic impairment in the oral phase of swallowing was independently predictive of worse swallowing-related quality of life. These findings highlight the need for clinicians to consider how impairments in swallowing physiology may impact the quality of life more broadly for patients with dysphagia.

Adherence to commercial food thickener in patients with oropharyngeal dysphagia

BACKGROUND

Oropharyngeal dysphagia (OD), a common symptom in the elderly, uses commercial thickener (CT) as part of its treatment. This is often accompanied of dislike and poor compliance.

AIM

Describe adherence to CT and possible differences according to dwelling location in an area of influence of approximately 400.0000 inhabitants.

METHODS

Cohort prospective observational study. Randomized patients from Nutrition and Dietetic (NDU)-database (4 calls-interviews/year).

VARIABLES

Age, diagnostic, gender, dwelling/location: Home (H) / Nursing Home (NH), viscosity (nectar, honey, pudding), days with CT. Adherence measured with a questionnaire, considering implementation of treatment by combining CT use and consumption data, categorised in three groups good, moderate and poor. Change in patterns (improvement, maintenance, worsening) and non-adherence reasons.

RESULTS

One hundred sixty-eight patients recruited with indicated viscosity: Nectar 39.7%, honey 29.3% and pudding 30.8%. Average age of 82.6 ± 11.1 years; 57.8% women (46.4% at H vs. 67% at NH, p < 0.01). Dwelling/location: 80 (47.6%) live at H and 88 (52.4%) at NH. Days with CT prior study were 509 ± 475.28. Implementation found in first call: good in 50%, moderate in 20.2% and poor in 29.8%. At first call, adherence parameters were more favourable in NH compared to H. However these parameters were reversed during the study period as there was an improvement at H vs. NH. Also in terms of change in patterns a significant improvement of implementation was found in patients living at H, 31.1% vs. those living at NH, 15.7%, p < 0.05. CT persistence throughout study was 89.7%.

CONCLUSIONS

Low adherence to CT found in our community. Telephone follow-up resulted in improved adherence, especially in the H population. Our data provides valuable insights into the variability and changes in CT adherence among patients with OD. Adherence is complex and subject to many factors and dwelling/location is one of them. This study reveals the need to approach CT treatment for OD differently in NH.

A Survey of Manual Therapy Techniques and Protocols Used to Prevent or Treat Dysphagia in Head and Neck Cancer Patients During and after Radiation Therapy

Background

Authoritative research demonstrating efficacy of traditional dysphagia therapy for Head & Neck Cancer (HNC) patients is limited. A 2019 survey reported speech-language-pathologists (SLPs) have started using Manual Therapy (MT) to prevent or rehabilitate dysphagia in HNC patients. This application of MT is supported theoretically but no research has established efficacy. Further, specific contents of MT protocols employed in this setting remain unknown.

Objectives

In the absence of HNC dysphagia specific MT protocols, this study aimed to better understand MT protocols employed by SLPs to prevent and treat dysphagia in HNC patients during and after Radiation Therapy (RT).

Methods

An internet-based questionnaire for SLPs who use MT with HNC patients was developed and tested for face/content validity. It was sent to SLPs practicing in the USA, twice, through three national listservs (ASHA-SIG13, ASHA-SIG3, University of Iowa Voiceserv).

Results

Of 64 respondents, 44 completed the survey. Of the 44, 15(34%) provided proactive MT during RT, 37(84%) provided proactive MT after RT (to prevent dysphagia), and 44(100%) provided reactive MT after RT (to treat dysphagia). 40(91%) were trained in MT through a CE course and 25(57%) had HNC-specific MT training. The most common MT techniques were laryngeal manipulation (LM) and myofascial release (MFR). During RT, MT protocols are gentler and highly tailored, with simple home programs of mild intensity. After RT, protocols are more regimented and aggressive, but still highly customized, with more diverse home programs of at least moderate intensity.

Conclusion

MT for HNC patients lacks a standard protocol or approach, but MFR and LM, or components of those techniques, are used most frequently. Given the frequency with which MFR and LM are employed to treat dysphagia during and post-RT, and the lack of empirical evidence supporting or refuting their use, a collaboratively designed RCT is warranted to establish the safety and efficacy of MT for HNC patients.

Oral somatosensory alterations and salivary dysfunction in head and neck cancer patients

PURPOSE

Patients with head and neck cancer (HNC) are at high risk of malnutrition due to eating difficulties partly mediated by sensory alterations and salivary dysfunction. Clinical studies have mostly focused on taste and smell alterations, while changes in oral somatosensory perception are largely understudied. The study aimed to investigate oral somatosensory (tactile, texture, chemesthetic, and thermal) responses and salivary functions of HNC patients in comparison to healthy controls.

METHODS

A cross-sectional study was conducted using psychophysical tests in HNC patients (n = 30) and in age- and gender-matched control subjects (n = 30). The tests included measurements of point-pressure tactile sensitivity, whole-mouth chemesthetic stimulation, food texture discrimination, and temperature discrimination. Salivary functions, including hydration, saliva consistency, pH, volume, and buffering capacity, were also evaluated.

RESULTS

HNC patients demonstrated significantly lower chemesthetic sensitivity (for medium and high concentrations, p < 0.05), thermal sensitivity (p = 0.038), and salivary functions (p = 0.001). There were indications of lower tactile sensitivity in the patient group (p = 0.101). Patients were also less sensitive to differences in food roughness (p = 0.003) and firmness (p = 0.025).

CONCLUSION

This study provided evidence that sensory alterations in HNC patients extend beyond their taste and smell. The measurements demonstrated lower somatosensory responses, in part associated with their reduced salivary function. Oral somatosensory alterations and salivary dysfunction may consequently impart the eating experience of HNC patients. Thus, further investigations on food adjustments for this patient group seem warranted.

Prevalence, Incidence, and Predictors of Self-reported Swallowing Difficulties in Community-Dwelling Adults: A Population-Based Study from the Canadian Longitudinal Study on Aging (CLSA)

There is a paucity of evidence from population-based studies identifying prevalence and incidence of dysphagia, as well as health and sociodemographic risk factors that may contribute to its development. As such, the current study aimed to determine prevalence, incidence, and associated predictors of dysphagia in adults. The Canadian Longitudinal Study on Aging is a nationally representative population study that follows 51,338 Canadians over 45 years of age. Biological, medical, psychological, social, lifestyle and economic data are collected. A secondary analysis of the data was conducted to determine prevalence, incidence, and the predictors of self-reported swallowing difficulty in adults between 45 and 85 years of age. Rates of swallowing difficulty by demographic risk factor, as well as lifestyle and health factors were analyzed using descriptive statistics. Associations between lifestyle and health variables with dysphagia were tested using Chi-square tests or t tests, as appropriate. Logistic regression was used to determine the predictors of self-reported swallowing difficulties. Overall prevalence of self-reported swallowing difficulties in adults over the age of 45 was 10.6% and increased to 13.7% after 3 years. Significant differences (p < 0.001) in self-reported swallowing difficulty at baseline were apparent across smoking status, requiring help to prepare meals, life satisfaction, social participation, all disease categories except dementia, number of medications, cognition, oral health status, and frailty. Incidence of dysphagia was 8.6%. Regression analyses suggested the following independent predictors of reports of swallowing difficulty: older age; non-white ethnicity; female sex; poor oral health; malnutrition; and frailty. These predictors should be carefully considered to ensure we are screening at-risk populations. Social determinants of health, such as ethnicity, must also be considered to ensure equitable care across the population.

The use of liquid formulation pentoxifylline and vitamin E in both established and as a prophylaxis for dental extractions "at risk" of osteoradionecrosis

BACKGROUND

Osteoradionecrosis (ORN) of the jaws remains one of the most debilitating complications of radiotherapy (RT) in patients with head and neck cancer (HNC). Liquid pentoxifylline and vitamin E (PVe) presents an alternative formulation to tablets for patients with dysphagia or enteric feeding.

OBJECTIVE

This study aimed to assess the clinical outcomes of using a liquid formulation of PVe for both established ORN and as a prophylaxis to avoid its occurrence after dental extractions. A secondary objective was to determine patient-reported side effects in relation to the liquid formulation of PVe.

STUDY DESIGN

The clinical records of 111 patients with HNC who were prescribed liquid PVe were reviewed retrospectively (66 with established ORN and 45 as prophylaxis before an invasive dental procedure).

RESULTS

In established ORN, 44% healed, and 41% were stable. In the prophylaxis group, 96% of surgical sites healed completely, with 4% (n = 2) developing ORN. Most patients (89%) were able to tolerate liquid PVe. Of the 11% (n = 12) who could not tolerate this regime, the most commonly reported side effect was gastric irritation (n = 5/12), whereas no more than 1 patient reported dizziness, malaise, and bleeding.

CONCLUSIONS

This retrospective review suggests that liquid PVe is efficacious for both established ORN and as a prophylaxis. Side effects reported were similar to those recognized for the tablet formulation.

Partners of persons with severe swallowing dysfunction have significantly reduced mental health

INTRODUCTION

Dysphagia can result in malnutrition, dehydration, social isolation, depression, pneumonia, pulmonary abscess, and death. The effect of dysphagia on the health and quality of life (QOL) of the life partners of persons with dysphagia is uncertain. We hypothesize that the partners of individuals with significant dysphagia will experience a significant reduction in quality of life.

PURPOSE

To evaluate the QOL of the significant others of persons with swallowing dysfunction.

METHODOLOGY

Persons with significant swallowing dysfunction (defined as EAT10® > 10) and their significant others were prospectively administered the 10-item Eating Assessment Tool (EAT10®) patient-reported outcome measure and the 12-item SF quality of life instrument (SF12). Summary data from the 8 mean health domains were compared between patients and their significant others. Mean scores for each domain are calibrated at 50, and a score below 47 implies significantly diminished QOL for a particular domain.

RESULTS

Twenty-three couples were evaluated. The mean ± SD EAT10 score for persons with significant dysphagia was 21 ± 7; mean EAT10 for their significant others or for couples in the control group was 0.3 ± 0.8. The mean physical health composite score (PCS) was significantly lower for patients with dysphagia compared to their significant others (39.1 ± 10 and 46.2 ± 11, respectively) (p < 0.05). Both patients and their significant others had comparable mean mental health composite scores (MCS) of 46.6 ± 10 and 46.4 ± 10, respectively (p > 0.05).

CONCLUSION

Although significant others of persons with swallowing dysfunction have higher physical well-being than their partners, they exhibit the same reduction in mental well-being, which is significantly lower than the general population. The data suggest that clinicians should address the mental well-being of the partners of persons with severe swallowing dysfunction.

Transadaptation and Validation of the Telugu Version of the Dysphagia Handicap Index

Dysphagia Handicap Index (DHI) is a clinically effective, concise, and user-friendly tool for assessing the functional impact of dysphagia in clinical populations. The present study aims to trans-adapt the DHI in the Telugu language and assesses its psychometric properties. The present study was conducted in two phases. The first phase includes translating and adapting the DHI tool into Telugu (T-DHI). The second phase includes an analysis of the psychometric properties of the trans-adapted Telugu version of the DHI. The DHI was translated into the Telugu language using the forward-backward translation method. The psychometric analysis was done on 100 participants. All the participants underwent a detailed clinical swallow examination after filling the T-DHI. The overall internal consistency and Guttmann split-half reliability for the Telugu version of the DHI were good. The correlation between the T-DHI subscales and the self-perceived severity of dysphagia was found to be high. The comparison of the T-DHI scores of the control and experimental groups revealed a significant difference. The T-DHI is a reliable and valid tool to assess the quality of life of the Telugu-speaking dysphagia population.

Optimizing Function and Appearance After Head and Neck Reconstruction: Measurement and Intervention

Approximately 50% of head and neck cancer (HNC) survivors are left with dysphagia as a result of treatment sequele, and 25% of survivors experience clinically significant body image distress (BID). Both dysphagia and BID adversely affect quality of life and should be tracked using validated clinician- and patient-reported outcome measures such as the Performance Status Scale for Head and Neck Cancer, MD Anderson Dysphagia Inventory, and Inventory to Measure and Assess imaGe disturbancE-Head & Neck (IMAGE-HN). Subjective and objective evaluation measures are critical to dysphagia workup and management. Building a renewed image after head and neck cancer treatment, a brief telemedicine-based cognitive behavioral therapy, has become the first evidence-based treatment for BID among HNC survivors.

Impact of anxiety and depression on the swallowing process among patients with neurological disorders and head and neck neoplasia: systemic review

Background

Dysphagia is associated with depression and anxiety due to the severity, impact of symptoms itself or secondary to the underlying cause. This is more recognizable to brain diseases that has consequences common to the neural supply of the swallowing act and the cognition and behavior. Limited data are available to explore, quantitate and monitor these neurological outcomes. Our aim of this research to review the literature pertinent to depressive disorders, anxiety, and/or the quality of life (QoL) and psychological well-being. Search of Medline and Google Scholar databases for relevant articles had revealed a total of 1568 citations; 30 articles met the inclusion and exclusion criteria.

Results

Data about the direct effect of dysphagia on psychiatric aspects are limited. Studies of the relationship between severity of dysphagia and depressive symptoms demonstrated that several evaluation tools are available for objective and subjective assessment. The severity and progression of dysphagia was significantly associated with increased depressive symptoms.

Conclusion

Dysphagia is associated with and positively correlated to depression and anxiety scores observed in Parkinson disease (PD), multiple sclerosis (MS) and stroke. Similar association is observed in patients with head and neck cancer, tongue cancer and oral cancer. A bidirectional positive correlation exists with a vicious circle that loops between dysphagia and psychological disease. Moreover, the severity of dysphagia shows correlation with depression and/or anxiety scores (Fig. 1, Graphical abstract).

Graphical Abstract

Investigating Predictive Factors of Dysphagia and Treatment Prolongation in Patients with Oral Cavity or Oropharyngeal Cancer Receiving Radiation Therapy Concurrently with Chemotherapy

Radiation therapy (RT) treatment for head and neck cancer has been associated with dysphagia manifestation leading to worse outcomes and decrease in life quality. In this study, we investigated factors leading to dysphagia and treatment prolongation in patients with primaries arising from oral cavity or oropharynx that were submitted to radiation therapy concurrently with chemotherapy. The records of patients with oral cavity or oropharyngeal cancer that received RT treatment to the primary and bilateral neck lymph nodes concurrently with chemotherapy were retrospectively reviewed. Logistic regression models were used to analyze the potential correlation between explanatory variables and the primary (dysphagia ≥ 2) and secondary (prolongation of total treatment duration ≥ 7 days) outcomes of interest. The Toxicity Criteria of the Radiation Therapy Oncology Group (RTOG) and the European Organization for Research and Treatment of Cancer (EORTC) were used to evaluate dysphagia. A total of 160 patients were included in the study. Age mean was 63.31 (SD = 8.24). Dysphagia grade ≥ 2 was observed in 76 (47.5%) patients, while 32 (20%) experienced treatment prolongation ≥ 7 days. The logistic regression analysis showed that the volume in the primary site of disease that received dose ≥ 60 Gy (≥118.75 cc, p < 0.001, (OR = 8.43, 95% CI [3.51-20.26]) and mean dose to the pharyngeal constrictor muscles > 40.6 Gy (p < 0.001, OR = 11.58, 95% CI [4.84-27.71]) were significantly associated with dysphagia grade ≥ 2. Treatment prolongation ≥ 7 days was predicted by higher age (p = 0.007, OR = 1.079, 95% CI [1.021-1.140]) and development of grade ≥ 2 dysphagia (p = 0.005, OR = 4.02, 95% CI [1.53-10.53]). In patients with oral cavity or oropharyngeal cancer that receive bilateral neck irradiation concurrently with chemotherapy, constrictors mean dose and the volume in the primary site receiving ≥ 60 Gy should be kept below 40.6 Gy and 118.75 cc, respectively, whenever possible. Elderly patients or those that are considered at high risk for dysphagia manifestation are more likely to experience treatment prolongation ≥ 7 days and they should be closely monitored during treatment course for nutritional support and pain management.

Preliminary Study of the Effects of a Dysphagia Support Group on Quality of Life

PURPOSE

Dysphagia (swallowing difficulties) can greatly decrease quality of life for individuals with dysphagia and can lead to caregiver burden and third-party disability. Support groups have been shown to be effective in improving quality of life in a range of conditions, through allowing individuals to form connections with those with shared experiences and sharing and learning about relevant resources and coping skills. However, no research on the effects of dysphagia support groups on quality of life has been conducted. This preliminary study aimed to determine whether a virtual support group, facilitated by speech-language pathologists, could positively affect quality of life in similar ways for adults with dysphagia and their family caregivers.

METHOD

Pre- and postsupport group surveys were sent to participants to gain information about their dysphagia, demographics, and support group feedback (e.g., access to resources). Questions were mainly multiple choice, with three open-ended questions related to the support group.

RESULTS

Eight individuals participated in the surveys, with four completing both pre- and postsession surveys. Seven of eight individuals reported that they felt a support group could improve their quality of life, with the eighth being unsure. Qualitative data found the support group offered both informational (e.g., resource access) and psychosocial support (e.g., knowledge that they were not alone, emotional support).

CONCLUSION

These initial results suggest that a dysphagia support group could fill a gap in the health care system to offer more holistic support to individuals with dysphagia and their family caregivers.

Translation and Validation of the Tamil Version of the Dysphagia Handicap Index in Tamil-Speaking Patients

Introduction Dysphagia is one of the general symptoms encountered in clinical practice. The impact of dysphagia can be devastating to a patient's physical condition and quality of life (QOL). To evaluate the QOL of patients with dysphagia there are numerous self-reported questionnaires. The most commonly used one such questionnaire is the Swallowing Quality-of-Life Questionnaire (SWAL-QOL). However, it is not concise and is incomplete as it does not address all the aspects of dysphagia. To overcome this, the Dysphagia Handicap Index (DHI) was developed. It focuses on the functional and emotional aspects in addition to the physical aspects of dysphagia. Objective To develop a Tamil version of the DHI (DHI-T) and assess its reliability, cultural adaptability and validity. Materials and method This cross-sectional study was conducted from May 2021 to December 2022 on 140 participants consisting of 70 dysphagia patients and 70 healthy individuals. Results The reliability and validity of the DHI-T were good with a high correlation between DHI-T and self-perceived severity scales of dysphagia. The mean total score in the Dysphagia group was 59.77 with the mean physical, functional and emotional scores being 23.86, 17.46 and 18.46 respectively. These scores were less compared to the Healthy group (p-value <0.01). Conclusion This study shows that DHI-T can be used as a reliable and valid tool to grade and study the different domains of dysphagia in our study population. Among the various causes of dysphagia studied in our population, it was noted that coronavirus disease 2019 (COVID-19)-related dysphagia patients had higher mean score in the emotional domain. To the best of our knowledge, the DHI scores for COVID-19-related dysphagia have not been done before. As the application of DHI in routine clinical practice and research is increasing, we believe this DHI-T can be of aid to Tamil-speaking patients.

Position Statement of the Union of European Phoniatricians (UEP): Fees and Phoniatricians' Role in Multidisciplinary and Multiprofessional Dysphagia Management Team

The need for multidisciplinary and multiprofessional management of dysphagia is constantly increasing and creating a major challenge for healthcare professionals and society, especially in terms of professional expertise and human resources. The distribution of tasks among the dysphagia team members, which includes phoniatricians, otolaryngologists, and speech-language therapists, is flexible and overlapping. For assessing dysphagia, the (fibreoptic) flexible endoscopic evaluation of swallowing (FEES), with or without videofluoroscopy, is a pivotal diagnostic tool. This position paper aims to illustrate the phoniatrician's role in performing a FEES, which is an indispensable component of the diagnostic workup of patients suffering from oropharyngeal dysphagia. It is based on the current collaborative expert view of the Swallowing Committee of the Union of European Phoniatricians and a literature review. A FEES is one of the core competences of phoniatricians due to their endoscopic expertise and experience in the field of dysphagia and diseases of the upper aerodigestive tract. Therefore, the phoniatrician is an important member of the dysphagia team, for the medical diagnostics of the aerodigestive tract and dysphagia as well as for FEES. Phoniatric competence is especially important for head and neck cancer patients, infants, and complex cases.

Oropharyngeal dysphagia and cachexia: Intertwined in head and neck cancer

BACKGROUND

This study aims to investigate the relationship between cancer cachexia and oropharyngeal dysphagia (OD) in patients with head and neck cancer (HNC) prior to chemoradiotherapy or bioradiotherapy (CRT/BRT).

METHODS

A prospective cohort study with patients with HNC undergoing CRT/BRT (2018-2021) was conducted. Body composition and skeletal muscle function were evaluated using bioelectrical impedance analysis, handgrip strength, and the short physical performance battery (SPPB). The M. D. Anderson Dysphagia Inventory (MDADI), Eating Assessment Tool (EAT)-10 questionnaire, and patient characteristics were collected. A standardized videofluoroscopic swallowing study was offered to patients.

RESULTS

Sixty-six patients were included. Twenty-six patients scored EAT-10 ≥ 3 and seventeen were cachectic. ACE-27 score >1, cachexia, abnormal SPPB-derived repeated chair-stand test, lower MDADI scores, and higher overall stage grouping showed potential predictive value (p ≤ 0.10) for EAT-10 ≥ 3. Using multivariable regression analysis, only cachexia remained a significant predictor of EAT-10 ≥ 3 (HR 9.000 [95%CI 2.483-32.619], p = 0.001).

CONCLUSION

Cachexia independently predicted the presence of patient-reported OD.

How Valid and Reliable Is the International Dysphagia Diet Standardisation Initiative (IDDSI) When Translated into Another Language?

Swallowing difficulties are estimated to affect 590 million people worldwide and the modification of food and fluids is considered the cornerstone of dysphagia management. Contemporary practice uses the International Dysphagia Diet Standardisation Initiative (IDDSI), however, the validity and reliability of IDDSI when translated into another language has not been investigated. This study describes the translation process and confirms the validity and reliability of IDDSI when translated into another language (Swedish). The translation used a 12-step process based on the World Health Organization recommendations. Validity was tested using Content Validity Index (CVI) based on three ratings by a panel of 10-12 experts (Dietitians and Speech-Language Pathologists [SLPs]). The translation was rated for linguistic correlation as well as understandability and applicability in a Swedish context. Inter-rater reliability was calculated using Intraclass Correlation Coefficient (ICC) from 20 SLP assessments of 10 previously published patient cases. Significant improvement (p < 0.05) of CVI between Expert Panel assessments was shown for linguistic correlation (improvement from 0.74-0.98) and understandability/applicability (improvement from 0.79-0.93 across ratings). Excellent validity (Item-CVI > 0.78 and Scale-CVI/Average > 0.8) and very high inter-rater reliability (ICC > 0.9) were demonstrated. Results show that, when using a multi-step translation process, a translated version of IDDSI (into Swedish) demonstrates high validity and reliability. This further contributes to the evidence for use of IDDSI.

A Decision Guide for Assessing the Recently Extubated Patient's Readiness for Safe Oral Intake

BACKGROUND

Postextubation dysphagia is a known consequence of endotracheal intubation. Several risk factors for postextubation dysphagia have been identified that could be used to help determine which patients should undergo swallowing assessment by an appropriate professional.

LOCAL PROBLEM

At the authors' institution, critical care nurses, health care providers, and speech-language pathology professionals lacked a clear process for referring patients for swallowing assessment after extubation, resulting in inefficiency and confusion. Information to guide their decision-making in this area was needed. To address this need, a multidisciplinary group convened and developed a guide with specific indicators.

METHODS

A review of the literature on postextubation dysphagia was conducted to determine the most appropriate indicators for the guide, which was piloted in the medical intensive care unit. The utilization rate was calculated. Referrals to speech-language pathology professionals were tabulated before and after the project.

RESULTS

During the 11 months before implementation of the project, there were 994 speech-language pathology consultations for postextubation evaluation of swallowing. During the 11 months after implementation, there were 831 consultations, representing a 16.4% reduction. The decline in consultations resulted in cost savings in addition to preventing unnecessary testing before patients' resumption of oral intake. The utilization rate for the guide during the project was 58%.

CONCLUSION

The decision guide was an effective tool to help nurses and health care providers determine which patients should be referred to speech-language pathology professionals for swallowing assessment after extubation, facilitating the appropriate use of limited health care resources.

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.

Preventive measures for the progression of dysphagia in patients with cancer of head and neck subjected to radiotherapy: a systematic review with meta-analysis

PURPOSE

To identify the effects of prophylactic, non-pharmacological measures on the progression of dysphagia in patients with head and neck cancer undergoing radiotherapy.

RESEARCH STRATEGIES

The search was performed in Medline (via PubMed), Scopus, and Embase databases, as well as in the gray literature.

SELECTION CRITERIA

Randomized clinical trials were included, with adult patients (≥ 18 years old) and diagnosed with head and neck cancer, treated with radiotherapy (with or without surgery and chemotherapy), and submitted to non-pharmacological protocols for the prevention of dysphagia.

DATA ANALYSIS

The risk of bias was assessed using the PEDRO scale and the overall quality of evidence was assessed using the GRADE instrument.

RESULTS

Four studies were considered eligible, and of these, two were included in the meta-analysis. The result favored the intervention group, with a mean difference of 1.27 [95% CI: 0.74 to 1.80]. There was low heterogeneity and the mean score for risk of bias was 7.5 out of 11 points. The lack of detail in the care with selection, performance, detection, attrition, and reporting biases contributed to the judgment of the quality of the evidence, considered low.

CONCLUSION

Prophylactic measures to contain dysphagia can promote important benefits on the oral intake of patients with head and neck cancer when compared to those who did not undergo such a therapeutic measure during radiotherapy.

Translation and Validation of the Dysphagia Handicap Index in Polish-Speaking Patients

Dysphagia Handicap Index (DHI) is a self-assessment questionnaire which consists of 25 statements to examine three aspects of dysphagia patients’ quality of life (QoL): functional, physical, and emotional. The patient can get a maximum score of 100 points. The study goal was to validate and translate the Polish version of the DHI (PL-DHI). One hundred and seventy-eight (178) individuals with oropharyngeal dysphagia with different etiology and 35 (thirty-five) asymptomatic adults with no history of swallowing disorders filled out the PL-DHI. Internal consistency was determined using Cronbach alpha coefficient, which was high for the total PL-DHI score (0.962). The reproducibility was high (r-Spearman correlation coefficient was 0.97 for total PL-DHI score). The PL-DHI’s total score and its subscales were significantly higher in the dysphagia patients study group (SG) than in the healthy controls group (CG) (SG median: 36; CG median: 4). A strong correlation was observed between the PL-DHI score and the self-reported dysphagia severity measure (Spearman’s correlation coefficient was 0.859, p < 0.001). The Polish DHI is a reliable and valid questionnaire for assessing dysphagia patients’ QoL.

Dental management before radiotherapy of the head and neck region: 4-year single-center experience

OBJECTIVE

To review our experience with a standardized dental management approach in patients with planned radiotherapy of the head and neck region based on preradiation and follow-up data.

MATERIAL AND METHODS

Records of patients who underwent radiotherapy between June 2016 and November 2020 were reviewed. Data on dental findings and therapeutic recommendations were extracted from a prospectively managed database. Hospital records were used to obtain follow-up data.

RESULTS

Two hundred eighty-one patient records were identified. After the exclusion of 81 patients because of incomplete data, 200 patients were included in the study. Dental findings relevant to radiotherapy were found in 144 cases (72.0%). Teeth extractions were recommended in 112 (56.0%) patients. Follow-up data were available for 172 (86.0%) patients (mean follow-up: 16.8 ± 10.7 months). Radiodermatitis was the most frequently observed sequela of radiotherapy (42.4%), followed by dysphagia (38.4%) and stomatitis (36.6%). Osteoradionecrosis was observed in only 2.3% of the patients.

CONCLUSION

Dental findings relevant to planned radiotherapy were frequent and in many cases resulted in recommendations for teeth extraction. Based on our standardized dental management protocol, we observed low rates of late oral complications after radiotherapy of the head and neck region.

Cross-cultural Adaption, Validation and Factor Analysis of the Persian Version of the Eating Assessment Tool: EAT-10

The eating assessment tool (EAT-10) is a self-reported questionnaire to assess the patient's perception of swallowing difficulties. The aim of this study was to cross-culturally adapt and determine validity and reliability of the Persian version of the EAT-10 (P-EAT-10) in patients with oropharyngeal dysphagia. The EAT-10 was translated into Persian language and cross-culturally adapted. One hundred patients with dysphagia (mean age ± SD = 44.44 ± 14.69 years) participated. The test-retest reliability (time interval = 7 days) was assessed in 50 patients. Intraclass correlation coefficient (ICC), standard error of measurement (SEM) and smallest detectable change (SDC) were analyzed. The Persian version of functional oral intake scale (FOIS-P) was also recorded to assess construct validity. One hundred healthy subjects completed the P-EAT-10 for clinical validity. Factor analysis was performed to determine the P-EAT-10 structure. There were no missing responses and floor or ceiling effects. Internal consistency was high (Cronbach's α 0.91). Item-total correlations exceeded acceptable standard of 0.3 for the all items (0.62-0.83). The test-retest reliability was excellent [(ICC)agreement 0.96]. The SEM and SDC were 2.61 and 7.23, respectively. Construct validity was confirmed by a significant correlation between the P-EAT-10 and FOIS-P scores (r = 0.84). Clinical validity was supported by a significant discrimination between patients and healthy subjects (t = 29.97, P < 0.001). Factor analysis indicated 2 components for the P-EAT-10. The P-EAT-10 is a valid and reliable tool and can be used in clinic and research for the assessment of oropharyngeal dysphagia in Persian-speaking patients.

Investigation of the Effect of Radiotherapy Dose on Chewing and Swallowing Structures in Head and Neck Cancer Patients Treated with Concomitant Chemoradiotherapy

Intensity-modulated radiotherapy (IMRT) is a treatment method that is used in the treatment of head and neck cancers. Impairment of chewing and swallowing functions in the early and late periods of radiotherapy is frequent. Therefore, revealing the dose-effect relationship is important. The main purpose of this study is to investigate the dose-effect relationship between chewing and swallowing structures objectively via a standardized videofluoroscopy protocol. The study included 35 participants treated with chemo-IMRT. A videofluoroscopic swallowing study (VFSS) was performed before IMRT, and 3 and 6 months after IMRT. VFSS results were scored according to the Modified Barium Swallow Impairment Profile (MBSImP) and the Penetration-Aspiration Scale (PAS). Maximum interincisor mouth opening, body mass index (BMI), and Functional Oral Intake Scale levels were determined in these cases. The quality of life of participants was evaluated. There was a significant increase in PAS and MBSImP scores and a significant decrease in BMI scores of the patients after treatment. Xerotomy and sticky saliva complaints increased after treatment. The dose to the mastication muscles (> 40 Gy) and the temporomandibular joint (> 46 Gy) were found to be associated with a decrease in BMI; the dose to the superior pharyngeal constructor muscle (> 58 Gy) was found to be associated with pharyngeal stripping wave. The presence of aspiration was associated with the inferior pharyngeal constructor muscle, glottic larynx, supraglottic larynx, and upper esophageal sphincter. Important findings to emerge from this study include detected toxic dose limits. These findings may guide physicians to minimize the side effects of IMRT.

Impact of Swallowing Impairment on Quality of Life of Individuals with Dysphagia

To explore oral intake and quality of life measures among individuals with dysphagia. This cross-sectional study with purposive sampling included 15 individuals with dysphagia. Functional oral intake scale (FOIS) and Dysphagia Quality of Life questionnaire in Marathi (DQOL-QM) were administered on individuals with dysphagia to evaluate oral intake levels and swallow related quality of life respectively. Data was collected using the interview method via tele-mode. Statistical analysis using Spearman's rank correlation revealed significant negative correlation (ρ = - 0.87) between oral intake and overall quality of life of the individuals with dysphagia. This negative impact was observed across all the domains of their quality of life. A considerable negative impact on quality of life was observed with declining oral intake of the individual with dysphagia. As oral intake plays an important role in the quality of life, decisions regarding the mode of feeding must be guided by the preferences of the individual and their family. strategies that enhance oral intake improves quality of life of dysphagic individual.

Dietary and Nutritional Support in Gastrointestinal Diseases of the Upper Gastrointestinal Tract (I): Esophagus

The esophagus is the centerpiece of the digestive system of individuals and plays an essential role in transporting swallowed nutrients to the stomach. Diseases of the esophagus can alter this mechanism either by causing anatomical damage that obstructs the lumen of the organ (e.g., peptic, or eosinophilic stricture) or by generating severe motility disorders that impair the progression of the alimentary bolus (e.g., severe dysphagia of neurological origin or achalasia). In all cases, nutrient assimilation may be compromised. In some cases (e.g., ingestion of corrosive agents), a hypercatabolic state is generated, which increases resting energy expenditure. This manuscript reviews current clinical guidelines on the dietary and nutritional management of esophageal disorders such as severe oropharyngeal dysphagia, achalasia, eosinophilic esophagitis, lesions by caustics, and gastroesophageal reflux disease and its complications (Barrett's esophagus and adenocarcinoma). The importance of nutritional support in improving outcomes is also highlighted.

Cross-Cultural Adaptation and Validation of the European Portuguese Dysphagia Handicap Index

The Dysphagia Handicap Index (DHI) is a valid Health-related Quality of Life (HRQoL) 25-item questionnaire assessing the physical, functional, and emotional aspects of patients with oropharyngeal dysphagia (OD), of heterogeneous etiologies. The purpose of this study is to translate and validate the European Portuguese-DHI (EP-DHI). This is a prospective study that was carried out at Centro Hospitalar Universitário do Porto (CHUPorto). The generated EP-DHI was administered to 132 patients with OD and 112 healthy control subjects. 132 patients undergoing fiberoptic endoscopic examination of swallowing (FEES). 15 patients were contacted by phone, 2 or 3 weeks later after the first interview to repeat the questionnaire. The validity of concurrent criteria was evaluated by comparing the results of the EP-DHI score with the score attributed to the pathological findings found in FEES and, consequently, Functional Oral Intake Scale (FOIS). The internal consistency of EP-DHI was successful: Cronbach's alpha coefficient for total EP-DHI was 0.874. The test-retest reliability for the total and the three EP-DHI subscales obtained a Pearson's correlation coefficient ranged from 0.990 to 0.712. This study demonstrates that EP-DHI is a valid tool for self-assessment of the handicapping effect of dysphagia on physical, functional, and emotional aspects of patient's quality of life, among an European Portuguese sample.
