Dysphagia Treatment for Patients With Head and Neck Cancer Undergoing Radiation Therapy: A Meta-analysis Review

Short- and Long-Term Swallowing Outcomes in Head and Neck Cancer Patients Receiving TORS and Adjuvant Therapy

BACKGROUND

Dysphagia (difficulty swallowing) is a common morbidity resulting from the treatment of head-and-neck squamous-cell carcinoma (HNSCC) due to surgery and chemoradiation. Transoral robotic surgery (TORS) is a minimally invasive surgical technique for the management of HNSCC, which ideally avoids many of the known complications of open surgery. Research describing physiologic swallowing impairment after surgery using videofluoroscopy is lacking.

METHODS

We evaluated videofluoroscopic swallowing studies of 37 patients who received TORS for head and neck cancer using a validated scoring tool, the Modified Barium Swallow Impairment Profile (MBSImP), at three time points including baseline.

RESULTS

Patients had worsened physiologic impairments in the immediate post-operative and late post-operative periods, particularly in components related to airway protection. Many patients also had baseline swallowing impairment.

CONCLUSIONS

Further research is required to elucidate dysphagia at discrete time points before and after treatment as well as with different and evolving adjuvant therapy protocols.

International consensus on laryngeal preservation strategies in laryngeal and hypopharyngeal cancer

This Policy Review summarises an expert Delphi consensus process on larynx-preservation treatments in patients affected by intermediate-to-advanced laryngeal or hypopharyngeal squamous cell carcinoma. The experts, who represented all perspectives involved in multidisciplinary management of these patients and included patient representatives, approved 137 consensus statements that cover several relevant areas in the field of larynx-preserving treatments. Statements are grouped in the following topics: granular indications for T2-T3 cancer, indications for T4a cancer, indications for salvage organ-preservation surgery after chemoradiation failure, laryngeal function at baseline, which comorbidities are contraindications and to what extent, organ preservation in older patients: selection criteria, post-treatment surveillance, prognostic and predictive factors, listening to the patient's preferences: tools and implementation, prehabilitation and rehabilitation protocols, and cost-effectiveness of different laryngeal preservation approaches. We present a high-level summary of the results of the consensus process, with detailed reference to the full list of statements and supporting literature.

Does swallow rehabilitation improve recovery of swallow function after treatment for advanced head and neck cancer

This study aimed to assess the prevalence, severity, and progression of swallowing impairments in head and neck cancer (HNC) patients before and after treatment, using videofluoroscopy with the Modified Barium Swallow Impairment Profile (MBSImP) protocol. We retrospect survey 90 HNC patients was divided into rehabilitation (receiving swallowing rehabilitation) and non-rehabilitation groups. All participants underwent a videofluoroscopic swallowing study with MBSImP, the Penetration-Aspiration Scale (PAS), and the Swallowing Performance Status (SPS) scale, along with assessments using the EAT-10 and Functional Oral Intake Scale (FOIS) at baseline, and at 1 and 3 months post-treatment. In all patients, MBSImP, PAS, and FOIS scores worsened one month after therapy. However, patients who performed swallow exercises demonstrated statistically significant improvements in swallowing function (FOIS and EAT-10) and related quality of life (EAT-10, Reflux Symptom Index) after three months of rehabilitation. High aspiration rates (poor PAS scores) were observed in all HNC patients post-treatment, peaking at 1 month and persisting over time. Notably, the rehabilitation group showed recovery of swallowing function to pre-treatment levels. Dysphagia is a significant and enduring side effect that impacts the quality of life in HNC patients undergoing multimodal treatment. The study suggests that a proactive swallowing rehabilitation program can positively influence outcomes, particularly after 3 months of rehabilitation.

Dysphagia, nutritional status, and quality of life in patients with head and neck cancer undergoing radiotherapy alone or combined with chemotherapy: an observational study

INTRODUCTION

Radiotherapy (RT) is the most common nonsurgical treatment for head and neck cancer (HNC) and may or may not be combined with chemotherapy (CT). Dysphagia, characterized by impaired swallowing function, is one of the most common side effects of RT, occurring during and after RT, and may persist long after treatment.

OBJECTIVE

To compare the evolution of dysphagia, nutritional status, and quality of life (QoL) in the periods immediately before and after RT for HNC in individuals who received only RT or combined RT/CT.

METHODS

Prospective longitudinal observational study performed in a hospital of the Brazilian public health system. The individuals were allocated into two groups: RG (n = 20), consisting of patients who received only RT for HNC, and RCG (n = 27), who received RT plus CT. The patients were evaluated before and after RT to identify and classify dysphagia (PARD protocol), anthropometric variables (BMI, triceps skinfold thickness, arm and calf circumferences, and manual dynamometry), and QoL (QLC-30 and H&N-35 questionnaires).

RESULTS

The groups were homogeneous in demographic characteristics and tumor stage. RCG showed a higher proportion of worsening dysphagia severity (p < 0.01) and worsening of anthropometric assessment (p < 0.05). A negative correlation was observed between the initial-final change in dysphagia and the change in BMI for the total sample (rho=-0.379, p < 0.05). QoL worsened in most domains evaluated, but RCG showed additional worsening in the domains of global health and nausea and vomiting (p < 0.05).

CONCLUSION

RT for HNC leads to the early development of dysphagia, which can adversely affect nutritional status and QoL. Including CT in the RT regimen leads to a more accentuated worsening of the evaluated parameters.

Impact of Transoral Robotic Surgery Versus Radiation on Swallowing Function in Oropharyngeal Cancer Patients: A Sub-Study From a Randomized Trial

BACKGROUND

This ORATOR sub-study evaluated swallowing physiology in patients treated with transoral robotic surgery (TORS) versus radiotherapy (RT) for early-stage oropharynx cancer.

METHODS

Swallowing physiology was evaluated using videofluoroscopy and outcomes were compared across treatment arms and correlated with MDADI scores.

RESULTS

Of the 68 patients in the ORATOR trial, 21 participated in this sub-study (30.8%), including 15 RT Arm and six TORS Arm patients. Swallowing profiles were not significantly different between the arms. MBSImP pharyngeal scores for RT Arm versus TORS Arm patients were 4.8 (±2.1) versus 4.3 (±1.5) at baseline, 6.2 (±1.2) versus 9.6 (±4.8) at 6 months and 5.9 (±1.8) versus 8.0 (±4.7) at 12 months. MBSImP pharyngeal scores demonstrated weak associations with several MDADI subscales and PAS scores.

CONCLUSIONS

To best describe swallowing outcomes in studies of RT and/or surgery, instrumental swallowing assessments should be strongly considered in addition to quality of life measures.

Development of a prediction model for tube feeding dependence in HPV-associated oropharyngeal cancer patients undergoing chemoradiotherapy

OBJECTIVES

This study aimed to develop a prediction model for feeding tube dependence in a large homogenous cohort of HPV-associated oropharyngeal squamous cell carcinoma (HPV + OPSCC) patients receiving chemoradiotherapy (CRT). We further aimed to externally validate three previously published feeding tube prediction models on this cohort.

MATERIALS AND METHODS

p16-confirmed HPV + OPSCC patients treated with definitive CRT at a tertiary cancer centre between April 2017 and February 2022 were identified. The primary endpoint was G-tube dependence, defined as enteral feeding for ≥ 4 weeks following CRT. Clinical and dosimetric data were extracted from electronic patient records. Multivariable analyses (MVA) assessed the associations of potential predictors with G-tube dependence. The discriminatory performance of three previously published models was assessed on this cohort using the area under the receiver operating curve (AUC), and calibration was evaluated with calibration plots.

RESULTS

A total of 291 patients were included (TNM8 stage I: 129; II:67; III: 95). MVA identified Dmean to the superior pharyngeal constrictor muscle, D70% to the middle pharyngeal constrictor muscle, and modified diet texture at baseline as predictive for G-tube dependence, with the AUC of 0.68. External validation of three existing models yielded an AUC of 0.60, 0.63, and 0.67, with no evidence of good calibration.

CONCLUSION

Despite a sizable cohort and comprehensive capture of dosimetric information, our prediction model, and external validation of previously published models, showed moderate performance. This suggests that additional factors beyond disease and treatment may need to be considered in future models to refine nutrition support decisions.

Impact of early swallowing rehabilitation on oral feeding in patients with dysphagia following traumatic brain injury

OBJECTIVE

This study aimed to evaluate the effects of early swallowing rehabilitation on safe oral feeding in dysphagia patients following traumatic brain injury.

METHODS

Sixty-nine patients were divided into intervention and control groups, with the intervention group receiving swallowing rehabilitation therapy. The severity of swallowing disorders, cognitive function, and level of consciousness were assessed using the Mann Assessment of Swallowing Ability (MASA), Rancho Los Amigos (RLA), and Glasgow Coma Scale (GCS) before and after the intervention. Additionally, data on ventilator use duration and hospital stay length were collected.

RESULT

The intervention group exhibited a significant improvement in MASA scores (68.58) compared to the control group (38.10). No significant differences were observed in GCS and RLA scores post-intervention, indicating similar levels of consciousness and cognitive function between groups. While the duration of ventilator use was comparable, the intervention group achieved safe oral swallowing 12.12 days earlier than the control group.

DISCUSSION

The findings demonstrate that early swallowing rehabilitation significantly enhances recovery dysphagia post-brain injury, as evidenced by improved MASA scores and earlier achievement of safe oral feeding, despite no notable changes in cognition or consciousness. This underscores the importance of implementing early rehabilitation strategies in clinical practice.

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.

Preventing radiation-induced dysphagia and trismus in head and neck cancer-A randomized controlled trial

BACKGROUND

Radiation-induced dysphagia and restricted mouth opening are common problems among patients with head and neck cancer. The aim of the present randomized controlled trial was to determine if an exercise protocol could prevent swallowing and mouth opening impairment.

METHODS

Eighty-nine participants were randomly assigned to either an active group performing preventive swallowing and mouth opening exercises (n = 45) or to a control group (n = 44). Outcome measures were collected at baseline before radiotherapy and approximately 1-month post-treatment. Primary endpoints were changes in swallowing function according to the Penetration Aspiration Scale and mouth opening ability measured in millimeters. Intention-to-treat analysis was used.

RESULTS

Swallowing function and mouth opening deteriorated in both groups, with no statistically significant positive effect of the protocol detected at follow-up. Among patients who completed >75% of exercises, there was a trend toward better outcomes.

CONCLUSIONS

Preventive exercises did not improve short-term swallowing function and mouth opening after radiotherapy.

Effects of Non-Pharmacological Interventions on the Swallowing Function of Patients With Post-Stroke Dysphagia: A Systematic Review and Network Meta-Analysis

BACKGROUND

Post-stroke dysphagia can lead to serious complications and appropriate rehabilitation can significantly improve swallowing function. However, the best rehabilitation method for post-stroke dysphagia patients is not clear at the present stage, so it is necessary to conduct a comprehensive network meta-analysis and systematic review of different interventions for dysphagia.

OBJECTIVE

To compare the effectiveness and ranking of different interventions for improving swallowing function, and feeding and daily function in patients with post-stroke dysphagia.

METHODS

Seven databases were searched from the date of inception to September 1, 2022. Two investigators independently conducted literature searches, selected randomized controlled trials on dysphagia interventions, and assessed study quality. Network meta-analysis was conducted by using Stata software.

RESULTS

A total of 33 studies involving 1,341 patients were included. According to the ranking probabilities, acupuncture was rated as the most effective of all interventions to enhance patients' swallowing function (surface under cumulative ranking curve values [SUCRCV]: 99.0%, standardized mean difference [SMD]: -2.40, 95% confidence interval [CI]: -3.38 to -1.43), followed by the chin tuck against resistance exercise (CTAR, SUCRA: 89.9%, SMD: -1.83, 95% CI: -2.69 to -0.97). Among all the interventions, acupuncture was the most effective for feeding and daily function (SUCRCV: 88.4%, SMD: -1.62, 95% CI: -2.94 to -0.30).

CONCLUSIONS

The results showed that acupuncture was the most effective in the rehabilitation of patients with post-stroke dysphagia, followed by CTAR. Considering that CTAR is a low-cost and highly feasible intervention, we suggest that CTAR should be selected as a rehabilitation measure for patients with post-stroke dysphagia to improve their swallowing function.

The Quantification of Radiation Fibrosis Using Clinically Indicated Magnetic Resonance Imaging for Head and Neck Cancer Patients

Currently, no objective method exists to measure the extent of fibrosis in swallowing musculature in head and neck cancer (HNC) patients. We developed and psychometrically tested a method of quantifying fibrosis volume using magnetic resonance imaging (MRI). The overall aim of this study was to determine if clinical MRI is a reliable tool to measure fibrosis of the pharyngeal musculature in patients with HNC managed with RT and to assess its potential to capture changes in fibrosis over time. Eligible participants were adults with HNC treated with radiation therapy (RT) who received minimally two MRIs and videofluoroscopic swallow (VFS) studies from baseline (pre-RT) up to 1-year post-RT. Two neuroradiologists independently contoured fibrosis volume in batches from MRIs using Vitrea™. Sufficient inter-rater reliability was set at Intraclass Correlation Coefficient (ICC) > 0.75. Two speech-language pathologists independently rated VFSs for swallowing impairment using standardized scales, with discrepancies resolved by consensus. MRI and VFS scores were correlated using Spearman's rank coefficient. Participants included 42 adults (male = 33); mean age 59 (SD = 8.8). ICC (95% Confidence Interval) for fibrosis volume was 0.34 (0, 0.76) for batch one and 0.43 (0, 0.82) for batch two. Consensus meetings were held after each batch. Sufficient reliability was reached by batch three (ICC = 0.95 (0.79, 0.99)). Fibrosis volume increased significantly from 3 to 12 months (mean change = 1.28 mL (SD = 5.21), p = 0.006), as did pharyngeal impairment from baseline to 12 months (mean score change = 3.05 (SD = 3.02), p = 0.003). Fibrosis volume moderately correlated with pharyngeal impairment at 3 and 12 months (0.49, p = 0.004 and 0.59, p = 0.005, respectively). We demonstrated a reliable measure of fibrosis volume in swallowing musculature from existing clinical MRIs and identified that larger fibrosis volume was associated with worse swallowing function. The reliable capture of fibrosis volume offers a pragmatic method for early detection of fibrosis and concomitant dysphagia.

Effect of nonpharmacological interventions on nutrition status, complications and quality of life in head and neck cancer patients undergoing radiotherapy: A systematic review and meta-analysis

PURPOSE

To evaluate the effect of nonpharmacological therapies on nutrition status, complications and quality of life in head and neck cancer patients and to provide a basis for clinical practice.

METHODS

This systematic review was reported in accordance with the Preferred Reporting Items for Systematic Review and Meta-analysis statement. Ten databases were systematically searched for all available articles from construction to November 2023. Two researchers independently conducted literature screening, data extraction and quality evaluation. Cochrane Review Manager 5.3 was used for meta-analysis.

RESULTS

Finally, 27 RCT studies including 2814 patients with head and neck cancer were included. Five categories of interventions were used: nutritional support, exercise, swallowing function training, psychological intervention and low-level laser therapy. Nonpharmacological interventions can improve body weight loss in patients with HNC at the end of treatment (MD: 1.66 kg; 95% CI: 0.80 to 2.51), and subgroup analysis showed that nutritional support, psychological intervention and low-level laser therapy were effective. Nonpharmacological interventions can also ameliorate decreases in BMI (MD: 0.71; 95% CI: 0.16 to 1.26) and reduce the incidence of malnutrition (RR: 0.76; 95% CI: 0.67 to 0.86), oral mucositis (RR: 0.54; 95% CI: 0.37 to 0.80) and gastrointestinal complications (RR: 0.61; 95% CI: 0.38 to 0.96) during radiotherapy; however, no significant differences were found in other complications and quality of life.

CONCLUSION

Nonpharmacological interventions can improve the nutrition status of patients with head and neck cancer and reduce the incidence of severe oral mucositis and gastrointestinal complications during radiotherapy but have no significant impact on quality of life.

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.

Pilot Study of Intensive Trismus Intervention Using Restorabite™ During Unilateral Adjuvant Radiation for Head and Neck Cancer

Trismus commonly arises after surgery for head and neck cancer (HNC) and its severity is potentiated by postoperative radiotherapy. While the benefit of trismus rehabilitation after surgery and radiotherapy is well established, the evidence during radiotherapy is less clear. This may be due to poor adherence to trismus exercises secondary to acute mucositis. This study assessed the feasibility of using a novel trismus device during adjuvant radiotherapy for HNC in patients with acute postoperative trismus. Prospective single-arm cohort feasibility study. Eligible patients had undergone surgery with curative intent for HNC, planned for adjuvant radiotherapy, and were suitable for trismus rehabilitation. Participants completed a 10-week exercise program using a novel jaw stretching device. Study outcomes were adherence, maximal incisal opening (MIO), and trismus-related function and quality of life scores, assessed at baseline, 10 weeks, and 6 months after commencing exercises. Nine patients diagnosed with trismus after primary surgery were recruited. The mean increase in MIO at 10 weeks was 7.8 mm (range -4 to 15 mm, p = 0.03), and at 6 months was 10.6 mm (range 1-26 mm, p = 0.03). Significant improvements were observed in trismus-related quality of life (Gothenburg Trismus Questionnaire; p = 0.04). Adherence to the exercises was 100% in week 1-2, 67% in weeks 3-6, and 100% at 10 weeks (1 month post radiation). This study demonstrates the feasibility of using a novel jaw stretching device during adjuvant radiotherapy. Further evaluation is warranted to assess the effectiveness of early intervention and prevention of trismus during HNC radiotherapy.Level of Evidence: IV.

Treatment of elderly patients with head and neck cancer in an aging society: Focus on geriatric assessment and surgical treatment

Previous studies of the treatment of elderly head and neck cancer (HNC) patients were very limited and sometimes controversial. Although conclusions differ across various reports, it is often concluded that advanced chronological age does not directly affect prognosis, but that comorbidities and declines in physical and cognitive functions promote the occurrence of adverse events, especially with surgical treatment. Geriatric assessment (GA) and its screening tools are keys to help us understand overall health status and problems, predict life expectancy and treatment tolerance, and to influence treatment choices and interventions to improve treatment compliance. In addition, personal beliefs and values play a large role in determining policies for HNC treatment for elderly patients, and a multidisciplinary approach is important to support this. In this review, past research on HNC in older adults is presented, and the current evidence is explained, focusing on the management of elderly HNC patients, with an emphasis on the existing reports on each treatment stage and modality, especially the surgical procedures.

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.

Exploring the Acceptability of Behavioral Swallowing Interventions for Head and Neck Cancer Patients During Radiotherapy: A Qualitative Study of Patients' Experience

The PRO-ACTIVE randomized clinical trial offers 3 swallowing therapies to Head and Neck Cancer (HNC) patients during radiotherapy namely: reactive, proactive low- ("EAT-RT" only), and high-intensity ("EAT-RT + exercises"). Understanding the perceived acceptability of these interventions is important to inform eventual implementation into clinical practice. This study explored patients' perspectives using qualitative methodology. At 2 Canadian PRO-ACTIVE trial sites, 24 trial participants were recruited for individual semi-structured interviews, representing each of the 3 trial arms. Data collection and thematic analysis were guided by the Theoretical Framework of Acceptability (TFA). Member checking was conducted through follow-up focus groups. Seven themes were derived reflecting the TFA constructs. Overall, regardless of trial arm, patients reported a positive experience with therapy. Patients identified benefits of EAT-RT therapy, reporting that it provided meaningful feedback on diet progress and supported goal setting for oral intake. Patients who received proactive therapies valued the opportunity to set expectations early, build mealtime routine iteratively over time, and have an extended engagement with the SLP. Regardless of trial arm, patients agreed proactive therapy aligned with what they think is best and that therapy intensity should accommodate individual needs. This study identified the value to HNC patients of receiving swallowing interventions during RT and setting realistic expectations around swallowing. Compared to reactive care, proactive therapies were perceived helpful in consolidating habits early, establishing realistic expectations around swallowing and building an extended rapport with the SLP. These findings will inform the implementation of proactive versus reactive swallowing therapies in clinical practice.

Post-Radiotherapy Dysphagia in Head and Neck Cancer: Current Management by Speech-Language Pathologists

OPINION STATEMENT

Dysphagia, difficulty in eating and drinking, remains the most common side effect of radiotherapy treatment for head and neck cancer (HNC) with devastating consequences for function and quality of life (QOL). Over the past decade, 5-year survival has improved due to multiple factors including treatment advances, reduction in smoking, introduction of the human papillomavirus (HPV) vaccine and more favourable prognosis of HPV-related cancers. Increased prevalence of HPV-positive disease, which tends to affect younger individuals, has led to an elevated number of people living for longer with the sequelae of cancer and its treatment. Symptoms are compounded by late effects of radiotherapy which may lead to worsening of dysphagia for some long-term survivors or new-onset dysphagia for others. Speech-language pathology (SLP) input remains core to the assessment and management of dysphagia following HNC treatment. In this article, we present current SLP management of dysphagia post-radiotherapy. We discuss conventional treatment approaches, the emergence of therapy adjuncts and current service delivery models. The impact of adherence on therapy outcomes is highlighted. Despite treatment advancements, patients continue to present with dysphagia which is resistant to existing intervention approaches. There is wide variation in treatment programmes, with a paucity of evidence to support optimal type, timing and intensity of treatment. We discuss the need for further research, including exploration of the impact of radiotherapy on the central nervous system (CNS), the link between sarcopenia and radiotherapy-induced dysphagia and the benefits of visual biofeedback in rehabilitation.

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.

Effect of voice training intervention on swallowing function in patients with head and neck cancer undergoing radiotherapy: A randomized controlled trial

PURPOSE

We aimed to evaluate the effect of voice training in patients with head and neck cancer who were undergoing radiotherapy.

METHOD

This study used a randomized controlled trial design. IBM SPSS 26.0 was used to randomly divide 74 patients into a control group and an experimental group. The control group followed a swallowing exercises program, and the experimental group additionally received ABCLOVE voice training. Both training programs continued throughout the entire radiotherapy cycle. We compared standardized swallowing assessment (SSA), maximum phonation time (MPT), the Voice Handicap Index-10, and incidence of complications such as difficulty opening the mouth, malnutrition, and aspiration between the two groups at T1 (0 radiotherapy sessions, before radiotherapy), T2 (15-16 radiotherapy sessions, middle of radiotherapy), and T3 (30-32 radiotherapy sessions, end of radiotherapy).

RESULTS

70 participants completed this study. Swallowing function and MPT intergroup and interaction effects were statistically significant between the two groups (P < 0.05). At the end of radiotherapy (T3), the SSA score (20.77 ± 1.96) and MPT (10.98 ± 1.75) s in the experimental group were superior to those in the control group (SSA: 22.06 ± 2.38 and MPT: 9.49±1.41 s), with statistical significance (P<0.05). Moreover, the incidence of malnutrition and aspiration in the experimental group was lower than that in the control group (P < 0.05).

CONCLUSION

Voice training can improve swallowing function and MPT and reduce complications related to swallowing disorders in patients with head and neck cancer.

Profiling of swallowing function in head and neck cancer patients prior to radiation therapy-Findings from a tertiary hospital in South India

Purpose

Head and neck cancer (HNC) patients often face difficulties with swallowing, which can be due to the cancer itself or the treatment modalities like radiation therapy. The presentation of HNC can vary between developing and developed countries due to socioeconomic factors. The current study aimed to profile the swallowing function of HNC patients before starting radiation therapy in a tertiary hospital in India.

Method

This cross-sectional observational study examined patients with HNC who were scheduled for radiation therapy. The Functional Oral Intake Scale (FOIS) and Karnofsky Performance Status Scale were used to assess the patients' swallowing status and functional abilities, respectively. The study also evaluated the relationship between swallowing function and clinical-demographic factors.

Results

Our assessment of 162 HNC patients found that the cancer site significantly affects swallowing. Although 92% of patients had an oral diet, 64% made dietary modifications. Patients with non-oral intake had either oral or pharyngeal cancer, and over 80% of oral cancer patients and 60% of those with pharyngeal cancer had already made changes to their diet. Patients with laryngeal cancer had a better oral intake, with 58% reporting no swallowing issues.

Conclusion

Patients with HNC scheduled for radiation therapy may experience varying degrees of swallowing difficulty. Early intervention and teaching of safe swallowing strategies are crucial to prepare for the potential worsening of swallowing difficulties resulting from the treatment. Advanced tumor stages and oral/pharyngeal cancers increase the risk of significant swallowing issues.

Revisiting Feeding Tube Utilization in Oropharynx Cancer: 6-Year Prospective Registry Analysis

OBJECTIVE

Patients treated for oropharyngeal cancer (OPC) have historically demonstrated high feeding tube rates for decreased oral intake and malnutrition. We re-examined feeding tube practices in these patients.

STUDY DESIGN

Retrospective analysis of prospective cohort from 2015 to 2021.

SETTING

Single-institution NCI-Designated Comprehensive Cancer Center.

METHODS

With IRB approval, patients with new oropharyngeal squamous cell cancer or (unknown primary with neck metastasis) were enrolled. Baseline swallowing was assessed via videofluoroscopy and Performance Status Scale for Head and Neck Cancer (PSSHN). G-tubes or nasogastric tubes (NGT) were placed for weight loss before, during, or after treatment. Prophylactic NGT were placed during transoral robotic surgery (TORS). Tube duration was censored at last disease-free follow-up. Multivariate regression was performed for G-tube placement (odds ratio [OR] [95% confidence interval [CI]) and removal (Cox hazard ratio, hazard ratio [HR] [95% CI]).

RESULTS

Of 924 patients, most had stage I to II (81%), p16+ (89%), node-positive (88%) disease. Median follow-up was 2.6 years (interquartile range 1.5-3.9). Most (91%) received radiation/chemoradiation, and 16% received TORS. G-tube rate was 27% (5% after TORS). G-tube risk was increased with chemoradiation (OR 2.78 [1.87-4.22]) and decreased with TORS (OR 0.31 [0.15-0.57]) and PSSHN-Diet score ≥60 (OR 0.26 [0.15-0.45]). G-tube removal probability over time was lower for T3 to T4 tumors (HR 0.52 [0.38-0.71]) and higher for PSSHN-Diet score ≥60 (HR 1.65 [1.03-2.66]).

CONCLUSIONS

In this modern cohort of patients treated for OPC, 27% received G-tubes-50% less than institutional rates 10 years ago. Patients with preserved baseline swallowing and/or those eligible for TORS may have lower G-tube risk and duration.

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.

The effects of Phoniatric PREhabilitation in Head and Neck Cancer patients on Aspiration and Preservation of Swallowing (PREHAPS): study protocol of a monocentric prospective randomized interventional outcome-blinded trial

BACKGROUND

Dysphagia, with its negative impact on life expectancy and quality of life, is a major side effect of head and neck squamous cell carcinoma (HNSCC). In a typical Head and Neck Cancer Center, more than half of patients are affected. Improving treatment, and ideally prevention respectively prehabilitation, therefore seems more than desirable.

METHODS

The study is planned as a monocentric, prospective, outcome-blinded, randomized interventional study comparing an advanced phoniatric-logopedic prehabilitation with a control (standard of care). Seventy patients (30 control group, 30 intervention group, 10 drop-out rate of 15%) with an initial diagnosis of invasive HNSCC and curative treatment intention will be included over a period of 17 months. In addition to the previous standard, both groups will undergo both detailed subjective assessment of swallowing function and quality of life by means of various questionnaires and objective analyses by bioelectrical impedance measurements and phoniatric endoscopic swallowing examinations. In the intervention group, risk-related nutritional counseling (face-to-face) and phoniatric-logopedic prehabilitation are provided: detailed counseling with video demonstration and exercises to strengthen and improve the range of motion of the oral, pharyngeal, and laryngeal muscles (guided by exercise diary). Controls are performed at 6 weeks, 3 and 6 months, and 9 or 12 months after the end of therapy during the regular tumor follow-up. Primary study endpoints are swallowing function and emotional distress at 6 weeks of control visit.

DISCUSSION

Prehabilitation measures have already proven successful in other patient groups, e.g., transplant patients. In the field of head and neck oncology, interest in such concepts has increased significantly in recent years. However, usually, only subgroups, e.g., patients with swallowing problems after radiochemotherapy alone, are in focus. Our study aims to investigate the general benefit of prehabilitation with regard to swallowing function, which is so important for protection of aspiration and quality of life.

Iterative Patient Testing of a Stimuli-Responsive Swallowing Activity Sensor to Promote Extended User Engagement During the First Year After Radiation: Multiphase Remote and In-Person Observational Cohort Study

BACKGROUND

Frequent sensor-assisted monitoring of changes in swallowing function may help improve detection of radiation-associated dysphagia before it becomes permanent. While our group has prototyped an epidermal strain/surface electromyography sensor that can detect minute changes in swallowing muscle movement, it is unknown whether patients with head and neck cancer would be willing to wear such a device at home after radiation for several months.

OBJECTIVE

We iteratively assessed patients' design preferences and perceived barriers to long-term use of the prototype sensor.

METHODS

In study 1 (questionnaire only), survivors of pharyngeal cancer who were 3-5 years post treatment and part of a larger prospective study were asked their design preferences for a hypothetical throat sensor and rated their willingness to use the sensor at home during the first year after radiation. In studies 2 and 3 (iterative user testing), patients with and survivors of head and neck cancer attending visits at MD Anderson's Head and Neck Cancer Center were recruited for two rounds of on-throat testing with prototype sensors while completing a series of swallowing tasks. Afterward, participants were asked about their willingness to use the sensor during the first year post radiation. In study 2, patients also rated the sensor's ease of use and comfort, whereas in study 3, preferences were elicited regarding haptic feedback.

RESULTS

The majority of respondents in study 1 (116/138, 84%) were willing to wear the sensor 9 months after radiation, and participant willingness rates were similar in studies 2 (10/14, 71.4%) and 3 (12/14, 85.7%). The most prevalent reasons for participants' unwillingness to wear the sensor were 9 months being excessive, unwanted increase in responsibility, and feeling self-conscious. Across all three studies, the sensor's ability to detect developing dysphagia increased willingness the most compared to its appearance and ability to increase adherence to preventive speech pathology exercises. Direct haptic signaling was also rated highly, especially to indicate correct sensor placement and swallowing exercise performance.

CONCLUSIONS

Patients and survivors were receptive to the idea of wearing a personalized risk sensor for an extended period during the first year after radiation, although this may have been limited to well-educated non-Hispanic participants. A significant minority of patients expressed concern with various aspects of the sensor's burden and its appearance.

Effectiveness of an evidence-based swallowing facilitation strategy for patients undergoing radiotherapy for head and neck cancer: a study protocol for a randomised controlled trial

INTRODUCTION

Dysphagia emerges as a frequent, persistent and enduring aftermath in individuals undergoing radiotherapy for head and neck cancer (HNC). Timely intervention becomes imperative to ameliorate prolonged dysphagia and curtail related complications. Among the evidence-grounded tactics, preventive swallowing training and proficient feeding management stand out as pivotal measures for precluding and mitigating dysphagia. However, past inquiries that amalgamated these dual interventions exhibited heterogeneous quality due to their restricted participant cohorts and a dearth of uniform, systematic and practicable procedural benchmarks.

METHOD/DESIGN

This randomised, parallel-controlled study enrols 94 patients diagnosed with HNC, who are undergoing radiotherapy either with or without concurrent chemotherapy. The patients will be randomly assigned to either the intervention group, which will receive a facilitation strategy to enhance swallowing function in conjunction with standard care, or the control group, which will receive typical radiotherapy care. Patient assessments will be conducted at three distinct time points: at the onset of radiotherapy (baseline), at the conclusion of radiotherapy and 3 months postradiotherapy. The primary outcome will revolve around measuring swallowing function, while secondary outcomes will encompass swallowing-related quality of life and nutritional status.

ETHICS AND DISSEMINATION

This research initiative received endorsement from the Shanghai Proton Heavy Ion Hospital Ethics Committee on 2 December 2 (Approval Number 2210-59-01). Throughout the recruitment process, patients will be acquainted with the primary aims and scope of the study. Their participation will be a voluntary choice, demonstrated by their informed consent form signatures. The outcomes of this study will be disseminated through publication in a peer-reviewed journal.

Oral Cavity Squamous Cell Carcinoma: Review of Pathology, Diagnosis, and Management

Squamous cell carcinoma of the oral cavity presents a significant global health burden, primarily due to risk factors such as tobacco smoking, smokeless tobacco use, heavy alcohol consumption, and betel quid chewing. Common clinical manifestations of oral cavity cancer include visible lesions and sores, often accompanied by pain in advanced stages. Diagnosis relies on a comprehensive assessment involving detailed history, physical examination, and biopsy. Ancillary imaging studies and functional evaluations aid in accurate staging and facilitate treatment planning. Prognostic information is obtained from histopathological factors, such as tumor grade, depth of invasion, lymphovascular invasion, and perineural invasion. Notably, lymph node metastasis, found in approximately half of the patients, carries significant prognostic implications. Effective management necessitates a multidisciplinary approach to optimize patient outcomes. Surgical resection is the backbone of treatment, aimed at complete tumor removal while preserving functional outcomes. Adjuvant therapies, including radiation and chemotherapy, are tailored according to pathological factors. Further work in risk stratification and treatment is necessary to optimize outcomes in squamous cell carcinoma of the oral cavity.

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.

Prehabilitation of dysphagia in the therapy of head and neck cancer- a systematic review of the literature and evidence evaluation

Background

Prehabilitation is becoming increasingly important in oncology because of the significant survival benefits that the reduction of malnutrition provide. Specifically, tumor- and therapy-related dysphagia leads to malnutrition in more than half of head and neck tumor patients. Studies describe the positive effects of an early onset of swallow-specific prehabilitation on the protection of the swallowing function. This paper intents to evaluate the existing evidence on the efficacy of preventive forms of swallowing therapy.

Methods

A systematic literature search was performed in February 2022 in the Cochrane Library, MEDLINE via PubMed, and ClinicalTrials.gov databases for randomized controlled trials investigating preventive swallowing therapy in head and neck tumor patients. This Procedure complies with the PRISMA statement. The RCTs were evaluated by using the PEDro Scale and the Cochrane Risk of Bias tool RoB2.

Results

Five randomized-controlled trials with 423 participants were identified. Four Studies showed moderate to high quality in the PEDro analysis, one showed less. The risk of bias was high in all studies because there was no possibility for blinding and there were high dropout rates. Heterogeneity in interventions, measurement instruments, measurement time points, and outcomes limits a general statement about which swallowing exercises are suitable for the prevention of dysphagia in head and neck tumor patients. Evidence is provided for short-term effects (≤24 months) on functional aspects of swallowing and quality of life. Overall, a decreasing adherence over time was observed in the intervention groups.

Discussion

Initial studies describe swallowing-specific prehabilitation programs in head and neck tumor patients as effective, at least in the short term, whereas long-term effects need to be further investigated. At the current time the evidence base for clear recommendations does not appear to be sufficiently high and studies share a high risk of bias. Further well-designed research, especially considering the conditions in the national health care system, is needed.

Managing eating problems after cancer

Cancer treatment can cause food-limiting eating problems that persist or arise months or years after treatment, with negative consequences for the survivor's nutritional status, physical and social function, and quality of life. Hence, post-treatment follow-up and cancer rehabilitation services should aim to support the survivor in managing treatment-related eating problems. This narrative review summarizes the evidence on and provides an overview of interventions to manage eating problems after cancer. Interventions are grouped into four: 1) food-based interventions, including alternating food/fluids and experimenting through the trial-and-error strategy to find tolerated foods; 2) eating behavioral interventions, including instructions on swallowing techniques, posture, and utensils; 3) psychosocial support interventions, including group-based interventions and interventions including relatives; and 4) physical interventions, including exercises to improve dysphagia or trismus. While physical interventions are supported by evidence from several intervention studies, few studies evaluating the effect of other types of interventions in survivors were identified. Instead, qualitative and observational data providing insights on experiences of and coping strategies applied by survivors with eating problems underpin the need for the other types of interventions. Since existing research primarily focuses on survivors of head and neck cancer, future studies on the organization and effects of interventions aimed at managing eating problems among different groups of survivors are relevant.

A randomized controlled study evaluating the head-lift exercise in head and neck cancer patients with radiation-induced dysphagia: effect on swallowing function and health-related quality of life over 12 months

PURPOSE

Dysphagia is common after radiotherapy for head and neck cancer (HNC) and can affect health-related quality of life (HRQL). This randomized controlled trial aimed to evaluate the effect of the head-lift exercise (HLE) over 12 months in HNC patients with radiation-induced dysphagia.

METHODS

Sixty-one patients with dysphagia were randomized to intervention group (n = 30) and control group (n = 31) at 6-36 months after completion of radiotherapy for HNC. Dysphagia-specific HRQL was measured with the MD Anderson Dysphagia Inventory (MDADI); general and HNC-specific HRQL was measured with the European Organization for Research and Treatment of Cancer Quality of Life questionnaire Core 30 (EORTC QLQ-C30) and QLQ-H&N35. Measurements were made at baseline, and at 8 weeks and 12 months after start of intervention.

RESULTS

Adherence to the intervention was good throughout the year. When comparing change from baseline reports to each follow-up no statistically significant differences between the groups were found in any of the HRQL instruments. There were some statistically significant changes within groups compared to baseline. The intervention group improved self-rated swallowing function on the MDADI at 8 weeks (emotional domain, p = 0.03; functional domain, p = 0.007; total score, p = 0.01) and the control at twelve months (emotional domain, p = 0.03; functional domain, p = 0.02; physical domain, p = 0.004; total score, p = 0.002).

CONCLUSION

In this randomized control study, no effect was observed short term or at 12 months on HRQL after use of the HLE as rehabilitation for radiation-induced dysphagia.

Palliative oral care in terminal cancer patients: Integrated review

BACKGROUND

Palliative care (PC) aims to improve quality of life in patients and its families against life threatening diseases, through suffering's prevention and relief. It is the duty of the dental surgeon to possess the knowledge needed to treat a patient with little life span, in order to establish an adequate treatment plan for each situation.

AIM

To synthesize the published evidence on oral conditions, impact, management and challenges in managing oral conditions among palliative patients.

METHODS

Articles were selected from PubMed and Scopus electronic platforms, using a research strategy with diverse descriptors related to "palliative care", "cancer" and "oral health". The article's selection was done in two phases. The first one was performed by the main researcher through the reading of the abstracts. In the second phase two researchers selected eligible articles after reading in full those previous selected. Data was tabulated and analyzed, obtaining information about what is found in literature related to this subject and what is necessary to be approached in future researches about PC.

RESULTS

As results, the total of 15 articles were eligible, being one a qualitative analysis, 13 (92.8%) clinical trials and one observational study. Of the 15 articles, 8 (53.4%) involved questionnaires, while the rest involved: one systematic review about oral care in a hospital environment, 2 oral exams and oral sample collection, one investigation of terminal patient's (TP) oral assessment records, 2 collection of oral samples and their respective analysis and one treatment of the observed oral complications.

CONCLUSION

It can be concluded that the oral manifestations in oncologic patients in terminal stage are, oral candidiasis, dry mouth, dysphagia, dysgeusia, oral mucositis and orofacial pain. Determining a protocol for the care of these and other complications of cancer - or cancer therapy - based on scientific evidence with the latest cutting-edge research results is of fundamental importance for the multidisciplinary team that works in the care of patients in PC. To prevent complications and its needed to initial the dentist as early as possible as a multidisciplinary member. It has been suggested palliative care protocol based on the up to date literature available for some frequent oral complications in TP with cancer. Other complications in terminal patients and their treatments still need to have further studying.

Speech and Swallowing Rehabilitation Potentially Decreases Body Weight Loss and Improves Survival in Head and Neck Cancer Survivors

This retrospective observational cohort study aims to assess the outcomes and associated factors in head and neck cancer (HNC) survivors with dysphagia, and to investigate the relationship between outcomes and speech and swallowing rehabilitation (SSR). We enrolled patients who were diagnosed with HNC between October 2016 and July 2018; we included 393 patients who developed dysphagia after definite treatment and were referred to speech-language pathologists (SLPs). We then classified patients into groups according to whether they received SSR. We used the clinical variables-including age, sex, site of malignancy, cancer stage, treatment modality, SSR, initial ECOG score, initial KPS, initial body weight (BW), and initial BMI-to evaluate the association between the percentage of BW change and overall survival (OS). There were 152 (39%) and 241 (61%) patients who received and did not receive SSR, respectively. In multivariate linear regression, SSR was significantly associated with percentage change in BW at 3 months post-treatment. Having SSR was positively associated with the percentage change in BW and decreased the BW loss [β coefficient (95% CIs) = 2.53 (0.92 to 4.14)] compared to having no SSR. In the multivariate Cox regression, SSR was an independent factor for OS. Compared to no SSR, the hazard ratio (95% CIs) for patients who received SSR was 0.48 (0.31 to 0.74). SSR helps to avoid BW loss and increases overall survival. HNC patients who develop dysphagia after treatment should be encouraged to participate in SSR.

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.

Voice Outcomes Following Head-Lift Exercises in Head and Neck Cancer: A Randomized Controlled Study

OBJECTIVES

This prospective randomized study aimed to investigate whether patients with dysphagia after treatment for head and neck cancer improve their vocal function from doing head lift exercises (Shaker's exercise).

METHODS

Patients were randomized into an intervention group (n = 24) or a control group (n = 26). Patients in the intervention group performed the head lift exercise three times a day for 8 weeks. At baseline and at follow-up after 8 weeks, participants' voices were evaluated perceptually with the Grade-Roughness-Breathiness-Asthenia-Strain (GRBAS) scale. Vocal fry (VF) was also perceptually evaluated and patients filled in the Voice Handicap Index (VHI).

RESULTS

Patients in the intervention group were perceptually evaluated as having less roughness and vocal fry in their voices at follow-up compared to the control group. There were no statistically significant changes between baseline and follow-up neither in the intervention nor the control group regarding GRBAS, VF, or VHI. Neither were there any statistically significant differences within the groups when results on the perceptual evaluations at baseline and follow-up were compared.

CONCLUSIONS

The voices of the participants in the intervention group were slightly better than the voices of the participants in the control group with less roughness and VF at follow-up. However, no improvement in the VHI or the remaining GRBAS variables was found. Therefore, this study can only give cautious support to the head lift exercise as a method for improving the voice of patients with dysphagia after treatment for head and neck cancer.

Absent epiglottic inversion as seen on flexible endoscopic evaluations of swallowing (FEES) is associated with a gestalt reduction in swallowing mechanics

PURPOSE

Epiglottic inversion, which provides one layer of the requisite protection of the airway during swallowing, is dependent on a number of biomechanical forces. The aim of this study was to examine the association between swallowing mechanics, as visualized during a Modified Barium Swallow (MBS) exam, and the rating of epiglottic inversion as seen on Flexible Endoscopic Evaluation of Swallowing (FEES).

METHODS

This study analyzed twenty-five adult outpatients referred for a simultaneous FEES/MBS exams. Each participant swallowed a 5 mL thin liquid bolus, which was the bolus size analyzed for this study's question. Epiglottic inversion, as seen on FEES, was rated by three independent raters. Additionally, twelve swallowing landmarks tracked the shape change of each participant's swallow on the MBS video using a MatLab-specific tracking tool. Analyses were run to determine mean differences in swallowing shape change between the swallows across 3 groups: complete, reduced, and absent epiglottic inversion, as seen on FEES. Using a Computerized Analysis of Swallowing Mechanics (CASM), canonical variate analyses and discriminant function testing were carried out. Other swallowing mechanics were also analyzed for kinematic movements to isolate the function of the hyoid and larynx. A two-sample t-test was conducted to compare mean hyolaryngeal movement between complete and incomplete epiglottic inversion groups.

RESULTS

Overall swallowing shape changes were statistically significantly different between the absent, reduced, and complete epiglottic inversion groups on FEES. Canonical variate analyses revealed a significant overall effect of shape change between the groups (eigenvalue = 2.46, p < 0.0001). However, no statistically significant differences were found on hyoid excursion (p = 0.37) and laryngeal elevation (p = 0.06) kinematic measurements between patients with complete and incomplete epiglottic inversion on FEES.

CONCLUSION

Epiglottic inversion on FEES is a valuable rating that infers reduced range of motion of structures that cannot be seen on FEES. This small sample of patients suggests that FEES ratings of absent epiglottic inversion may represent gestalt reduction in swallowing mechanics.

Dysphagia Advances in Head and Neck Cancer

Purpose of Review

This review summarises the current literature regarding head and neck cancer-associated dysphagia. Up-to-date evidence for dysphagia outcome measurement for this population is provided, in addition to recent innovations that aim to prevent, reduce or remediate the common and debilitating side effects of treatment.

Recent Findings

Both patient-reported outcomes and clinical measures are necessary to capture the multi-dimensional nature of swallowing. A minimally important difference in scores has been calculated for some of these measures, to aid interpretation and powering of clinical trials. The number of dysphagia-related trials has increased, predominantly investigating optimal treatment for oropharyngeal HPV-positive disease, and speech and language pathology interventions using an impairment-based approach.

Summary

Although substantial progress has been made, further work is necessary to establish a consensus over outcome measures. Modifying treatments may improve outcomes. Several trials are underway to establish the effectiveness of speech and language pathology dysphagia interventions.

Quality of Life, Psychological Distress, and Nutritional Status of Polish Patients with Head and Neck Cancer Treated with Radiotherapy

INTRODUCTION

Head and neck cancer (HNC) is a global epidemiological and clinical problem. In 2020, it was the seventh most common type of cancer worldwide. In 2019, HNC was the fourth most common cause of cancer death among men in Poland. Radiotherapy plays an important role in the treatment of patients with HNC at all clinical stages. However, it is associated with a significant rate of early and late adverse effects. As head and neck cancers are located close to vital anatomical structures, both the local progression of the disease and the treatments used can cause serious problems for patients with HNC, reducing their health-related quality of life (HRQoL) as well as increasing the risk of depressive disorders. Despite this, the current literature lacks research on these aspects of the therapeutic process in the Polish population. The aim of this study was to assess the early impact of radiotherapy on HRQoL outcomes, psychological distress, nutritional status, and overall performance of patients with HNC.

METHODS

The study was carried out among 85 patients with HNC treated in the Inpatient Radiotherapy Unit of the Radiotherapy Department of the Lower Silesian Oncology Center in Wrocław. The patients were asked to complete a set of questionnaires, including the EORTC QLQ-H&N35, the BDI, the NRS-2002, and the ECOG scale, at two time points: before the initiation of radiotherapy treatment and after a course of radiotherapy. The period between the assessments was 7 to 8 weeks.

RESULTS

Our findings demonstrated a negative impact of radiotherapy on scores in all the cancer-specific symptom and functioning scales used in the study. As regards functioning scales, the largest differences were observed for senses and swallowing, whereas with symptoms scales, the largest differences were noted for "sticky saliva" and "dry mouth". Over half of the patients included in the study required nutritional support after radiotherapy treatment. We found statistically significant differences in the levels of depressive symptom severity before and after radiotherapy treatment.

CONCLUSION

The present study showed significant changes in the physical and psychological functioning and nutritional status of the patients with HNC studied after radiotherapy treatment, which may have an impact on the effectiveness of cancer treatment.

Treatment with head-lift exercise in head and neck cancer patients with dysphagia: results from a randomized, controlled trial with flexible endoscopic evaluation of swallowing (FEES)

BACKGROUND

This randomized study aimed to evaluate the effects of the Shaker head-lift exercise (HLE) to improve dysphagia following oncologic treatment for head and neck cancer (HNC).

METHODS

Patients with dysphagia following oncologic treatment for HNC were randomly assigned to intervention (n = 23) or control (standard dysphagia management, n = 24) groups. Swallowing was evaluated at baseline and at 8-week follow-up using flexible endoscopic evaluation of swallowing (FEES) and self-perceived swallowing with the Eating Assessment Tool (EAT-10). Analysis was performed regarding secretion, initiation of swallow, residue after swallowing, and penetration/aspiration.

RESULTS

Few statistically significant differences were found in the FEES analysis. Some improvement of self-perceived swallowing function was found in both groups. Adherence to training was high.

CONCLUSIONS

This randomized study regarding the effect of the HLE demonstrated that swallowing outcome measures used in assessment of FEES did not improve in patients treated with radiotherapy for patients with dysphagia following HNC.

A Systematic Review of Swallowing Training Measures for Postoperative Oral Cancer Patients

Swallowing disorder is one of the most common postoperative complications for oral cancer patients and seriously influences quality of life. Limited attention has been paid to evaluating swallowing training measures in postoperative oral cancer patients. This study systematically reviewed swallowing training measures for these patients. A comprehensive search strategy was undertaken across various databases for studies published between database inception and 15 June 2021. Raters independently judged titles, abstracts and full articles for selection according to inclusion and exclusion criteria. The included literature was evaluated for quality and data were extracted. Meta-analyses were conducted using RevMan 5.3. Ten intervention studies (four randomized controlled trials and six quasi-experimental studies) involving 588 patients were identified. Across the studies, most started in the early postoperative stage; however, there were differences in starting time, training time and duration, and type of training. We summarized four training methods: oral exercise, oral sensory stimulation, compensatory strategies and protective airway manoeuvres. The meta-analysis indicated that swallowing training could improve patients' swallowing function and quality of life in the short term, but the long-term effects were not obvious. Swallowing training mostly occurred in the early postoperative period and training measures were often used in combination. The timing, frequency and content of interventions varied between studies, and the effectiveness of any single measure was unclear. High-quality randomized controlled trials are necessary to study the efficacy and clinical applicability of various training measures, to provide a theoretical basis for their optimal selection and to develop a standardized training programme for postoperative oral cancer patients.

Changes in oral function, swallowing function, and quality of life in patients with head and neck cancer: a prospective cohort study

Background

Head and neck cancer (HNC) treatment can cause oral morbidities, such as oral dryness and dysphagia, affecting the patient’s quality of life (QOL). The relationship between oral functions and QOL in patients with early-stage HNC remains poorly studied. This study aimed to evaluate changes in the QOL of patients with early-stage HNC and identify factors that affect the QOL of these patients.

Methods

In this prospective cohort study, 37 patients who underwent early-stage (Stage I/Stage II) HNC treatment were evaluated for their oral function, swallowing function, and the QOL score at baseline (BL) and 12 months after surgical treatment (12 M). The participants were divided into two groups: patients who returned to the BL QOL score at 12 M (RE; n = 26) and those who did not (NR; n = 11).

Results

In total, 29.7% (11/37) patients with early-stage HNC did not return to the BL QOL score at 12 M. There was no significant difference between the RE and NR groups regarding the oral and swallowing function. Moreover, oral and swallowing function of all patients returned to the BL at 12 M. The NR group showed lower QOL scores than the RE group in the global health status, and “sticky saliva” parameters in the questionnaires.

Conclusion

Restoration of the oral function is insufficient to improve the QOL of patients with early-stage HNC. The treatment of these patients should instead consider several factors that affect their QOL.

Adhering to Eat and Exercise Status During Radiotherapy for Oropharyngeal Cancer for Prevention and Mitigation of Radiotherapy-Associated Dysphagia

Importance

Previously published work reported independent benefit of maintenance of oral intake (eat) and swallowing exercise adherence (exercise) during radiotherapy (RT) on diet and functional outcomes. The current study seeks to validate the authors' previously published findings in a large contemporary cohort of patients with oropharynx cancer (OPC) and address limitations of the prior retrospective study using prospective, validated outcome measures.

Objective

To examine the longitudinal association of oral intake and swallowing exercise using validated, clinician-graded and patient-reported outcomes.

Design, Setting, and Participants

Secondary analysis of a prospective OPC registry including patients who underwent primary RT/chemoradiotherapy (CRT) or primary transoral robotic surgery plus RT/CRT for OPC at a single-institution comprehensive cancer center.

Exposures

Adherence to speech pathology swallowing intervention during RT coded as (1) eat: oral intake at end of RT (nothing by mouth [NPO]; partial oral intake [PO], with feeding tube [FT] supplement; full PO); and (2) exercise: swallowing exercise adherence (nonadherent vs partial/full adherence).

Main Outcomes and Measures

Feeding tube and diet (Performance Status Scale for Head and Neck Cancer) patient-reported swallowing-related quality of life (MD Anderson Dysphagia Inventory; MDADI) and clinician-graded dysphagia severity grade (videofluoroscopic Dynamic Imaging Grade of Swallowing Toxicity; DIGEST) were collected at baseline, 3 to 6 months, and 18 to 24 months post-RT.

Results

A total of 595 patients (mean [SD] age, 65 [10] years; 532 [89%] male) who underwent primary RT (111 of 595 [19%]), CRT (434 of 595 [73%]), or primary transoral robotic surgery plus RT/CRT (50 of 595 [8%]) were included in this cohort study. At the end of RT, 55 (9%) patients were NPO, 115 (19%) were partial PO, 425 (71%) were full PO, and 340 (57%) reported exercise adherence. After multivariate adjustment, subacute return to solid diet and FT were independently associated with oral intake (odds ratio [OR], 2.0; 95% CI, 1.0-4.1; OR, 0.1; 95% CI, 0.0-0.2, respectively) and exercise (OR, 2.9; 95% CI, 1.9-4.5; OR, 0.3; 95% CI, 0.1-0.5, respectively). Subacute MDADI (β = 6.5; 95% CI, 1.8-11.2), FT duration (days; β = -123.4; 95% CI, -148.5 to -98.4), and less severe dysphagia per DIGEST (OR, 0.6; 95% CI, 0.3-1.0) were independently associated with oral intake, while exercise was independently associated with less severe laryngeal penetration/aspiration per DIGEST-safety (OR, 0.7; 95% CI, 0.4-1.0). DIGEST grade associations with oral intake were not preserved long-term; however, exercise was associated with a higher likelihood of solid diet intake and better swallow safety per DIGEST.

Conclusions and Relevance

The findings of this cohort study extend the authors' previously published findings that oral intake and swallowing exercise during RT are associated with favorable functional outcomes, now demonstrated with broader domains of function using validated measures. Patterns of benefit differed in this study. Specifically, better subacute recovery of swallow-related quality of life and less severe dysphagia were found among patients who maintained oral intake independent of exercise adherence, and shorter FT utilization and better long-term diet and swallowing safety were found among those who exercised independent of oral intake.

Evaluation of Candidiasis in Upper-Aerodigestive Squamous Cell Carcinoma Patients—A Clinico-Mycological Aspect

Candida is a commensal yeast. It can be infective when the host’s defense mechanism is weakened, as in the case of squamous cell carcinoma patients. We aimed to evaluate the prevalence and clinical mycological manifestation of candidiasis in 150 cancer cases comprised of preoperative and post-operative (with or without radiotherapy) upper aerodigestive squamous cell carcinoma. A total of 150 patients suffering from squamous cell carcinoma of the Upper Aero-Digestive Tract (UADT) were divided into preoperative (n = 48), post-operative without radiotherapy (n = 29) and post-operative with radiotherapy (n = 73). Samples were collected using cotton swabs and cultured. Candida species were identified according to color pigmentation on Candida Differential Agar (CDA) plate. The clinico-mycological association of patients was evaluated by the chi-square test, and 98 out of 150 patients showed the presence of various Candida species. The major species isolated was Candida albicans (53%), followed by Candida tropicalis (16%). There was a significant statistical difference between patients who showed mycological associations and patients who did not have any such association (p = 0.0008). The prevalence of oral candidiasis was found to be 65.33% among total cases of upper aero-digestive squamous cell carcinoma. Chronic erythematous cases of candidiasis were mainly seen in preoperative squamous cell carcinoma cases, whereas the acute erythematous type of candidiasis was mainly seen in post-operative cases who received radiotherapy. The clinicomycological assessment can help to correlate the signs and symptoms with the presence of candidiasis in upper aerodigestive squamous cell carcinoma patients. Meticulous testing and examination can help in the early detection of candidiasis. Future studies are needed to develop advance scientific preventive strategies for high-risk cases.

[Pre-treatment dysphagia in head-and-neck cancer patients]

BACKGROUND

The swallowing and nutritional status of head-and-neck cancer patients after oncological therapy have been extensively researched. However, the same topics are seldom scrutinized before the onset of oncological therapy, although they can influence treatment success in the long term.

OBJECTIVE

This study focusses on a systematic assessment of swallowing function and nutritional status in head-and-neck cancer patients prior to oncological therapy.

MATERIALS AND METHODS

In 102 patients, penetration/aspiration (PA scale), limitations of oral intake (Functional Oral Intake Scale, FOIS), and the need for further intervention (NFI) were endoscopically assessed to objectively quantify swallowing function. The subjective evaluation of swallowing function was carried out with the gEAT-10 (German EAT-10) questionnaire, nutritional status was assessed by body mass index (BMI). Possible impact factors for swallowing function and BMI were analyzed by univariate and multivariate methods.

RESULTS

PAS, FOIS, and NFI values were abnormal in ≤ 15% of patients. BMI was more often too high than too low. Objectively assessed swallowing functions depended predominantly on tumor stage and showed moderate correlations with gEAT-10. The latter mostly yielded a "fail" result. The nutritional status depended on the patients' biological sex and NFI.

CONCLUSION

In the pre-treatment setting, neither dysphagia nor malnutrition were found in most patients. Impaired swallowing was associated with higher tumor stages, malnutrition with female sex and NFI. A systematic pre-treatment assessment of swallowing and nutritional status in head-and-neck cancer patients appears necessary for modern oncological therapy and optimal patient outcome.

Supplementation with Cod Liver Oil Capsules Reduces Weight Loss and Mucositis in Head and Neck Cancer Patients Undergoing Curative Radiotherapy without Affecting the Treatment Response

Background Weight loss is a common observation in head and neck cancer (HNC) patients and the severity depends on the modalities used. The purpose of this study was to evaluate the effectiveness of providing two capsules of fish oil supplement each day during the course of curative radiotherapy for HNC patients.

Materials and Methods This was a retrospective single-center study, and files of HNC patients treated with radiotherapy between the months of January 2015 and March 2015 were evaluated. Data on gender, age, tumor, treatment details, adverse effects, weight before and at the end of the treatment, and treatment response were obtained from the patient files. The data collected were entered into Excel sheet and subjected to statistical analysis using chi-square tests, unpaired t-test, and analysis of variance with post hoc Tukey test. A p-value of <0.05 was considered significant.

Results Records of 68 patients treated during the study period with radiation for HNC and admitted to the inpatient facility throughout the treatment period were retrospectively reviewed. Majority of the patients had advanced stage tumors. There was no difference in the initial weight of the patients in the two groups while a significant difference was seen in the final weight (p = 0.007). The number of patients with severe weight loss (>5 kg) was more in the control than in the fish oil cohort (68.89 vs. 43.48) and was significant (p = 0.042). In addition to this, the incidence of mucositis was delayed and also lesser in severity in the cohorts that had received fish oil. At the dose used, fish oil capsules did not have any adverse effects and importantly there was no significant difference in treatment response.

Conclusion The results of the study indicate that administering fish oil capsules was effective in arresting weight loss and delaying and mitigating mucositis in HNC patients undergoing curative radiotherapy. Fish oil capsule has good safety profile, was devoid of any toxic effects, and has a good clinical application value.

A prediction model for xerostomia in locoregionally advanced nasopharyngeal carcinoma patients receiving radical radiotherapy

Background

This study was to evaluate the predictors of xerostomia and Grade 3 xerostomia in locoregionally advanced nasopharyngeal carcinoma (NPC) patients receiving radical radiotherapy and establish prediction models for xerostomia and Grade 3 xerostomia based on the predictors.

Methods

Totally, 365 patients with locoregionally advanced NPC who underwent radical radiotherapy were randomly divided into the training set (n = 255) and the testing set (n = 110) at a ratio of 7:3. All variables were included in the least absolute shrinkage and selection operator regression to screen out the potential predictors for xerostomia as well as the Grade 3 xerostomia in locoregionally advanced NPC patients receiving radical radiotherapy. The random forest (RF), a decision tree classifier (DTC), and extreme-gradient boosting (XGB) models were constructed. The sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), area under the curve (AUC) and accuracy were analyzed to evaluate the predictive performance of the models.

Results

In the RF model for predicting xerostomia, the sensitivity was 1.000 (95%CI 1.000–1.000), the PPV was 0.990 (95%CI 0.975–1.000), the NPV was 1.000 (95%CI 1.000–1.000), the AUC was 0.999 (95%CI 0.997–1.000) and the accuracy was 0.992 (95%CI 0.981–1.000) in the training set. The sensitivity was 0.933 (95%CI 0.880–0.985), the PPV was 0.933 (95%CI 0.880–0.985), and the AUC was 0.915 (95%CI 0.860–0.970) in the testing set. Hypertension, age, total radiotherapy dose, dose at 50% of the left parotid volume, mean dose to right parotid gland, mean dose to oral cavity, and course of induction chemotherapy were important variables associated with the risk of xerostomia in locoregionally advanced NPC patients receiving radical radiotherapy. The AUC of DTC model for predicting xerostomia was 0.769 (95%CI 0.666–0.872) in the testing set. The AUC of the XGB model for predicting xerostomia was 0.834 (0.753–0.916) in the testing set. The RF model showed the good predictive ability with the AUC of 0.986 (95%CI 0.972–1.000) in the training set, and 0.766 (95%CI 0.626–0.905) in the testing set for identifying patients who at high risk of Grade 3 xerostomia in those with high risk of xerostomia.

Conclusions

An RF model for predicting xerostomia in locoregionally advanced NPC patients receiving radical radiotherapy and an RF model for predicting Grade 3 xerostomia in those with high risk of xerostomia showed good predictive ability.

Management of elderly patients with head and neck cancer

There are no established guidelines for managing older patients with head and neck cancer. Most clinical trials that define current standard therapy included few elderly patients. On the other hand, there is great variability in patients' comorbidities, physical functions, cognitive function, familial and financial background and values. The key point appears to be appropriate geriatric assessment, clarifying the patients' outcomes and a multidisciplinary team approach, including the treatment decision-making policy. Although these processes should be scientific in nature, the evidence for the treatment of elderly head and neck patients is very limited. This review summarizes the evidence available regarding the management of geriatric assessment, each treatment modality and the multidisciplinary team approach for older patients with head and neck cancers.

State of Rehabilitation Research in the Head and Neck Cancer Population: Functional Impact vs. Impairment-Focused Outcomes

PURPOSE OF REVIEW

Management of head and neck cancer (HNC) typically involves a morbid combination of surgery, radiation, and systemic therapy. As the number of HNC survivors grows, there is growing interest in rehabilitation strategies to manage HNC-related comorbidity. In this review, we summarize the current state of HNC rehabilitation research.

RECENT FINDINGS

We have organized our review using the World Health Organization's International Classification of Function (ICF) model of impairment, activity, and participation. Specifically, we describe the current research on rehabilitation strategies to prevent and treat impairments including dysphagia, xerostomia, dysgeusia, dysosmia, odynophagia, trismus, first bite syndrome, dysarthria, dysphonia, lymphedema, shoulder syndrome, cervicalgia, cervical dystonia and dropped head syndrome, deconditioning, and fatigue. We also discuss the broader impact of HNC-related impairment by exploring the state of rehabilitation literature on activity, participation, psychosocial distress, and suicidality in HNC survivors. We demonstrate that research in HNC rehabilitation continues to focus primarily on impairment-driven interventions. There remains a dearth of HNC rehabilitation studies directly examining the impact of rehabilitation interventions on outcomes related to activity and participation. More high-quality interventional studies and reviews are needed to guide prevention and treatment of functional loss in HNC survivors.
