Perceptions and experiences of post-irradiation swallowing difficulties in nasopharyngeal cancer survivors

Quality of life and swallowing outcomes after early proactive swallowing rehabilitation by either transcutaneous neuromuscular electrical stimulation or exercise-based swallowing training in patients with nasopharyngeal carcinoma after radiotherapy

Background

Exercise-based swallowing training (EBST) and transcutaneous neuromuscular electrical stimulation (TNMES) are common modalities used to treat late dysphagia after radiotherapy for nasopharyngeal carcinoma (NPC). We aimed to investigate and compare the efficacies of EBST and TNMES as proactive treatments administered early after radiotherapy.

Methods

Patients with early post-radiotherapy NPC (n = 120) underwent either TNMES or EBST. Flexible endoscopic evaluation of swallowing (FEES), quality of life (QOL), and swallowing function questionnaires were completed before the intervention as well as immediately, 6, and 12 months after the intervention. Outcome measures included the scores for the swallowing function score (SFS), penetration and aspiration scale (PAS), dynamic imaging grade of swallowing toxicity (DIGEST), functional oral intake scale (FOIS), swallowing performance status scale (SPSS), pharyngeal motor impairment (PMI), pharyngeal function impairment (PFI), and functional assessment after cancer therapy-nasopharyngeal (FACT-NP) questionnaire.

Results

Three months after radiotherapy, 31 and 34 patients underwent TNMES and EBST, respectively, and completed swallowing assessments at all four assessment timepoints. All patients showed post-radiotherapy impairments in the SFS, PAS, DIGEST, PMI, and PFI. Compared with the EBST group, the TNMES group showed significant improvements in the PFI and PMI scores, with small-to-medium effect sizes. Additionally, compared with the EBST group, the TNMES group demonstrated a trend toward slightly better improvements in the PAS, DIGEST, FOIS, and SPSS scores immediately and 6 months after the intervention. The SFS scores improved from baseline in both groups; however, the TNMES group showed an earlier improvement. Finally, the TNMES group showed better QOL according to the FACT-NP than the EBST group.

Conclusion

Proactive TMNES and EBST are safe and feasible modalities for improving swallowing in patients with NPC when administered early after radiotherapy. Although TNMES showed better results than EBST, these results should be interpreted with caution given the study limitations.

Stigma, self-efficacy and late toxicities among Chinese nasopharyngeal carcinoma survivors

OBJECTIVE

This study explores the level of stigma among Chinese nasopharyngeal carcinoma survivors, its influencing factors and relationship with self-efficacy.

METHODS

In total, 281 nasopharyngeal carcinoma survivors were recruited from China, who completed the demographic, disease-related and late toxicities questionnaire, as well as the General Self-Efficacy Scale and Social Impact Scale.

RESULTS

The mean scores for stigma and self-efficacy were 57.22 ± 9.58 and 28.06 ± 3.97, respectively, both showing a moderate level. The late toxicities with the highest incidence were xerostomia (91.8%), fatigue (78.3%) and hearing loss (63.0%). Stigma was significantly and negatively related to self-efficacy (r = -0.295, P < 0.001). Multivariable linear regression showed that self-efficacy, number of children, educational level, perceived support from spouse and other family members and some late toxicities (nasal obstruction and toothache) were influencing factors of stigma, accounting for 49.4% of the variance.

CONCLUSION

Medical staff should be more aware of stigma among Chinese nasopharyngeal carcinoma survivors, especially those with more children and weaker educational backgrounds who are at a higher risk of stigma. They should take effective measures to alleviate stigma by improving patients' self-efficacy, relieving late toxicities and encouraging spouses and family members to provide more support for them.

Experiences and perceptions of stroke patients living with dysphagia: A qualitative meta-synthesis

AIMS

To systematically review and synthesise the findings of qualitative research exploring experiences of dysphagia from stroke patients' perspectives.

BACKGROUND

Poststroke patients with dysphagia are suffering from impaired physical functions and heavy psychological burden, and they are living with compromised quality of life. Through synthesising qualitative studies to fully portrait the experiences of poststroke patients living with dysphagia, we can care better for this population.

DESIGN

A systematic review and synthesis of qualitative studies reported by following ENTREQ.

REVIEW METHODS

Five electronic databases (CINAHL, Embase, PubMed, Web of Science and Cochrane Library) and three Chinese databases (CNKI, VIP and Wanfang) were searched from inception until January 2021. Qualitative studies were included if they were related to the experiences of poststroke patients with dysphagia. The Joanna Briggs Institute Qualitative Assessment and Review Instrument (JBI-QARI) was used to appraise study quality. Data were synthesised using the Thomas and Harden method thematic and content analysis.

RESULTS

Five studies were included in the meta-synthesis. Four analytical themes were identified: life changes after dysphagia, coping with social events, rebuilding a normal life and limited professional services.

CONCLUSIONS

More attention should be given to psychological health and social interaction in poststroke dysphagia patients. Healthcare professionals, especially nurses, should make joint efforts to provide patients with dysphagia-related knowledge and long-term individualised support. To improve the quality of life of dysphagia patients, further research should implement high-quality interventions based on dysphagia experience and clinical treatment.

RELEVANCE TO CLINICAL PRACTICE

These findings outline the changes in poststroke patients with dysphagia. Nurses as the first-line force, should deliver comprehensive and individualised intervention for managing physiological and psychosocial symptoms of patients.

A qualitative systematic review of the social eating and drinking experiences of patients following treatment for head and neck cancer

PURPOSE

Patients living with and beyond head and neck cancer (HNC) often have long-term, functional challenges as a result of treatment. A key functional challenge relates to eating and drinking; often associated with physical, emotional, and social difficulties. Eating and drinking with family members and friends can become a struggle, increasing the risk of social isolation and loneliness. This systematic review aims to identify and synthesise the literature on the experiences of social eating and drinking for patients following treatment for HNC.

METHODS

Six electronic databases (Pubmed, Web of Science, CINAHL, EMBASE, PsychINFO, and Scopus) were systematically searched using subject headings and free-text word searches in February 2020. Citation chaining and Google Scholar were used to identify grey literature. PRISMA procedures were followed.

RESULTS

Of 6910 records identified, 24 studies met the inclusion criteria. Synthesis of the research findings results in two major themes: (1) the experience of loss associated with social eating and drinking, and (2) adjusting and support to promote social eating and drinking.

CONCLUSION

Losses associated with social eating affect a patient's psychological and emotional well-being and impact on close relationships. To promote positive participation in social eating, patients were more likely to seek and receive support from someone within their close social network, rather than a healthcare professional. Family and friends are an essential source of support and are integral in facilitating engagement with social eating following treatment for HNC. Future interventions should promote family orientated resources, incorporating self-management strategies.

Dysphagia after chemo-radiation for nasopharyngeal cancer: A scoping review

Objective

Nasopharyngeal cancer (NPC) has distinct characteristics regarding its global prevalence, initial presentation, management and patient outcomes compared to other subtypes of head and neck cancer (HNC). The mainstay of NPC treatment is chemo-radiation (C/RT) and while dysphagia is a known early and late toxicity of C/RT treatment, the nature of dysphagia post NPC treatment has had limited investigation. The objective of this review is to summarise the existing evidence regarding dysphagia following NPC to inform the future research agenda for this population. Dysphagia incidence, characteristic deficits observed across the phases of swallowing, efficacy of current dysphagia interventions, and effect on quality of life will be explored.

Data sources

Databases including MEDLINE, CINAHL, Embase, Scopus and Web of Science were included.

Methods

A scoping review was conducted according to PRISMA-ScR guidelines. Two independent reviewers screened selected full text articles.

Results

Of the initial 2495 articles found, 28 articles were included. Reports of penetration and aspiration varied widely (0%–91.6%), with high rates of silent aspiration identified in 2 studies (42%, 66%). Oral, pharyngeal and upper esophageal phase impairments were reported. Of these, upper esophageal stasis and multiple pharyngeal stage deficits were most prevalent. The pharyngeal constrictors were found to have a significant dose–effect relationship and shielding to the anterior neck field was effective to preserve swallowing function. Six treatment studies were identified with limited evidence supporting the use of neuromuscular electrical stimulation, dilatation and swallowing exercises. Quality of life was adversely affected.

Conclusions

Dysphagia is a prevalent early and late problem post NPC treatment, with impairments across all phases of the swallow. Studies on preventing dysphagia and treatment efficacy remain limited. More systematic study of the nature of dysphagia and the efficacy of treatment in this population is warranted.

To eat is to practice-managing eating problems after head and neck cancer

PURPOSE

The purpose of this qualitative study was twofold: (1) to explore head and neck cancer (HNC) survivors' experiences of everyday life with eating problems after cancer treatment and (2) to explore their experiences of participating in a multidisciplinary residential rehabilitation program with a primary focus on physical, psychological, and social aspects of eating problems after treatment.

METHODS

Semi-structured focus group interviews were conducted with 40 Danish HNC survivors who participated in a 5-day residential rehabilitation program with follow-up after 3 months. The transcribed interviews were analyzed through qualitative content analysis.

RESULTS

Physical nutrition impact symptoms and unmet needs for support were frequent. Participants experienced a feeling of loss due to impaired eating abilities. Eating had become an obligation or a training situation, and the eating problems challenged the relationship with their relatives when well-meaning encouragement was perceived as a pressure. Social eating was a challenge, and this often led to social withdrawal. The residential program was a safe and supportive environment to practice eating skills, and participants benefited from meeting peers. The program provided participants with knowledge and skills that many of them had been missing during and after treatment.

CONCLUSIONS

Eating problems after treatment have substantial effects on the everyday life of HNC survivors. A multidisciplinary residential rehabilitation program may be beneficial to meet their rehabilitation needs.

IMPLICATIONS FOR CANCER SURVIVORS

The results are useful for future planning of rehabilitation services and clinical studies that may contribute to improving current clinical practice and benefit HNC survivors.

Dying for a Meal: An Integrative Review of Characteristics of Choking Incidents and Recommendations to Prevent Fatal and Nonfatal Choking Across Populations

Purpose The purpose of this study was to conduct an integrative review of original research, across adult populations relating to fatal or nonfatal choking on food, to understand ways to respond to and prevent choking incidents. Method Four scientific databases (CINAHL, Medline, Web of Science, and EMBASE) were searched for original peer-reviewed research relating to fatal or nonfatal choking on foods. Data were extracted on study characteristics; factors leading up to, events at the time of, and actions taken after the choking incident; and impacts of choking incidents. An integrative review of the findings across studies identified several risk factors and recommendations to reduce the risk of choking. Results In total, 52 studies met the criteria for inclusion in this review, of which 31 were quantitative, 17 were qualitative, and 4 were of a mixed methods design. Studies reported the observations and narratives of bystanders or researchers, or else were large-scale autopsy studies, and included both the general public and people at risk of dysphagia. A range of food types were involved, and several actions were reported in response to food choking. Strategies to reduce the risk of choking were identified in the studies and are presented in 5 main categories. Conclusions Factors leading up to choking incidents extend well beyond the individual to the environment for mealtimes; the provision of appropriate mealtime assistance and oral care; and regular monitoring of general health, oral health, and medications. Bystanders' increased awareness and knowledge of how to respond to choking are vital. The results of this review could be used to inform service policy and training, for individuals at risk of choking, the people who support them, and the general public. Further research is needed to explore choking prevention and airway protection in individuals with dysphagia. Supplemental Material https://doi.org/10.23641/asha.8121131.

Radiation-Associated Chronic Dysphagia Assessment by Flexible Endoscopic Evaluation of Swallowing (FEES) in Head and Neck Cancer Patients: Swallowing-Related Structures and Radiation Dose-Volume Effect

PURPOSE

We aimed to restore dose-volume parameters of swallowing-related structures (SRSs) by evaluating long-term swallowing dysfunctions after radiotherapy (RT) in head and neck cancer patients (HNCPs).

MATERIALS AND METHODS

Head and neck cancer patients whose pharyngeal region was involved in RT portal and treated with definitive RT/chemoradiotherapy (CRT) were included in the analyses. Patients underwent objective swallowing assessment by flexible endoscopic evaluation of swallowing (FEES). Volumes of SRSs that received 55 Gy (V₅₅) (mean dose [D_mean]) were evaluated according to the dose-volume histograms of each patient. For every SRS, optimal dose-volume cut-off values were determined by receiver operating characteristic curve analysis.

RESULTS

Fifty-five patients at a median 20 months (range, 12-26 months) after their treatments were evaluated. There was a strong negative correlation between FEES scores and dose-volume parameters of SRS ( r ⩽ -0.5, P < .0001). According to our results, middle pharyngeal constrictor (MPC) and inferior pharyngeal constrictor (IPC) had a D_mean > 57 Gy, base of tongue (BOT) D_mean > 50 Gy, supraglottic larynx (SGL) and glottic larynx (GL) D_mean > 55 Gy, and cervical esophagus (CE) D_mean > 45 Gy. MPC V₅₅ > 70%, IPC V₅₅ > 50%, BOT V₅₅ > 65%, CE V₅₅ > 40%, and SGL and GL V₅₅ > 50% were significant predictors for dysphagia.

CONCLUSION

It was found that dysphagia correlates strongly with dose-volume parameters of SRSs. IPC, SGL, and CE were found to be structures significantly associated with dysphagia.

Vastus Lateralis Muscle Free Flap for Skull Base Osteoradionecrosis in Nasopharyngeal Carcinoma

Objectives  To describe the first experience with a free vastus lateralis muscle-only flap to be used to cover and protect the exposed skull base and carotid artery from radiotherapy-induced skull base osteoradionecrosis (ORN). Design  Retrospective review of a case series. Setting  Tertiary academic medical center. Participants  Post treatment nasopharyngeal carcinoma patients with skull base ORN. Main Outcome Measures  Coverage of the internal carotid artery (ICA). Results  Four patients underwent the procedure. Following the procedure, all patients were documented to have adequate viable soft tissue covering their ICA. Topical nasal steroids were prescribed to all patients as florid granulation tissue was noted to occur overlying the muscle flap in the early postoperative period. There were no flap failures. All patients noted an improvement in speech, cacosmia, and nasal crusting. No significant epistaxis occurred following surgery. Choanal stenosis was noted in three patients. Conclusion  For skull base ORN resulting from the treatment of nasopharyngeal carcinoma (NPC) with radiotherapy that fails conservative management, an open approach to the nasopharynx, that allows debridement then placement of a vastus lateralis muscle-only free flap for coverage, offers a unique and viable approach to the management of this challenging condition.

Psychometric Properties of the Chinese Version of the M.D. Anderson Dysphagia Inventory for Head and Neck Cancer Patients

BACKGROUND

Dysphagia is a common side effect of anticancer treatments in patients with head and neck cancer (HNC) and can worsen patients' quality of life. A well-established measure is essential to evaluate dysphagia in HNC patients.

OBJECTIVES

The aim of this study is to determine the psychometric properties of the Chinese version of the M.D. Anderson Dysphagia Inventory (MDADI-C) for HNC patients.

METHODS

A total of 220 subjects were included in the study. Reliability was examined by internal consistency (Cronbach's α) and test-retest reliability (intraclass correlation coefficient). Validity was evaluated with Spearman correlations (r).

RESULTS

The Cronbach's α and intraclass correlation coefficient of the MDADI-C were .923 and 0.942, respectively. The criterion validity of the MDADI-C was 0.777. The Spearman correlation coefficients of the MDADI-C with the European Organization for Research Into the Treatment of Cancer Quality of Life Questionnaire for Head and Neck Cancer (r = -0.851), Hospital Anxiety and Depression Scale (r = -0.424), radiotherapy dose (r = -0.553), and treatment regimens (r = -0.407) demonstrated good construct validity (all P < .01).

CONCLUSIONS

The MDADI-C demonstrated good psychometric properties and would be a valuable tool for clinicians to screen dysphagia rapidly and evaluate its impact on the quality of life of HNC patients.

IMPLICATIONS FOR PRACTICE

The MDADI-C could be used to document and monitor the dysphagia level of HNC patients for clinicians, nurses, and researchers. This validated questionnaire will help nurses and doctors to improve dysphagia management in HNC patients and will allow researchers to compare the study results across different countries.

The Value of Qualitative Research in Dysphagia in the Head and Neck Cancer Population: What Can We Learn From the Survivors' Perspective?

Dysphagia is a common acute and long-term side effect of curative, non-surgical treatment for head and neck cancer (HNC). Despite what is known about dysphagia associated with HNC treatment in terms of its prevalence, severity, physiological characteristics, and the associated effects on quality of life (QoL), our understanding of the key factors which impact on HNC survivors is only just emerging. Whilst quantitative research studies have demonstrated that most people experience dysphagia in the early post-treatment period, and that many people continue to have ongoing swallowing issues for months and years following treatment, emerging qualitative research in this field has provided insights into the extent to which the presence of dysphagia impacts on the everyday lives of people with HNC. By exploring issues from the perspectives of people living with dysphagia, qualitative research has highlighted those factors that have the greatest impact on oral intake, raised issues for service provision, and highlighted the need for additional professional involvement and better long term supportive care.

Study of the medial group retropharyngeal node metastasis from nasopharyngeal carcinoma based on 3100 newly diagnosed cases

PURPOSE

Patterns of metastases to the medial retropharyngeal lymph nodes (RPLN) from nasopharyngeal carcinoma (NPC) have gain little attention. Since the incidence of dysphagia was closely related to whether the medial RPLN was irradiated, we carried out a prospective study to explore the patterns of the medial RPLN involvement.

METHODS AND MATERIALS

Previously untreated NPC patients were required to receive MRI scan. MRI scanning sequences included pre-contrast T1WI, T2WI, and post-contrast T1WI with fat suppression. All images were evaluated by the multi-disciplinary treatment group of NPC.

RESULTS

3100 cases of NPC entered this study. 2679 (86.4%) cases had involved lymph nodes. The detailed distribution were: 2341 (87.4%) in level IIb, 1798 (67.1%) in level IIa, 1184 (44.2%) in level III, 350 (14.1%) in level IV, 995 (37.1%) in level V, 115(4.3%) in level Ib, 2012 (75.1%) in the retropharyngeal area. But only 6 (0.2%) were located at the medial group, accompanied with the lateral RPLN and other node metastasis. Only one medial RPLN can be identified in a patient, whereas the number of the lateral RPLNs per affected side varied between one and four. The average size of the medial and lateral RPLNs was 8±4 mm (range, 4-17 mm) and 16±9 mm (range, 5-53 mm), respectively.

CONCLUSIONS

① Involvement of the retropharyngeal nodes were mainly located at the lateral group, the medial RPLN was rarely seen. ② Metastasis to the medial RPLN was always accompanied with other node metastasis. ③ Only one medial RPLN can be identified in a patient, whereas the enlarged lateral RPLNs per affected side could be multiple. ④ The average size of the medial RPLN was smaller than the lateral RPLNs.

The psychological experience of living with head and neck cancer: a systematic review and meta-synthesis

OBJECTIVE

To summarise patients' experiences of head and neck cancer (HNC) by examining the findings of existing qualitative studies

METHODS

We undertook a systematic review and meta-synthesis of qualitative studies in 29 published articles using Noblit and Hare's 'meta-ethnography' approach to synthesise findings. The inclusion criteria were primary qualitative studies, focusing on HNC patients' experience and an English abstract. Seven databases were systematically searched.

RESULTS

The articles focused on the experience of having HNC, the experience of treatments and the role of information. Our synthesis identified six core concepts-uncertainty and waiting, disruption to daily life, the diminished self, making sense of the experience, sharing the burden and finding a path. People experienced significant disruption to normal daily activities, because of the physical and emotional effects of HNC and its treatment. Day-to-day challenges were compounded by social and existential changes and a palpable loss of the individual's sense of self and future. In order to find a way through the considerable uncertainty and daily challenge of living with and beyond HNC, patients made continual efforts to make sense of their experience. Supportive relationships with their social network, HNC peers and healthcare professionals were particularly important, but support following treatment completion was sometimes limited. Perceptions of the future were affected by whether they saw life as diminished, merely changed or even enhanced by the experience of cancer.

CONCLUSIONS

This review supports further specific research into these emerging themes and provides a context for future work, informing interventions to improve patients' experiences.

Symptom experience and regaining normality in the first year following a diagnosis of head and neck cancer: a qualitative longitudinal study

INTRODUCTION

Symptom experiences and their interference with life are not well-researched in head and neck cancer patients. The aim of the study was to explore and understand the experience of receiving treatment for head and neck cancer with particular focus on symptom experiences over a one year period from diagnosis.

METHODS

A qualitative study design was used with a heterogeneous sample of 16 patients with head and neck cancer. Interviews, conducted at four time points over 12 months, provided a total of 50 interview datasets.

RESULTS

Key themes derived include nutritional concerns, tiredness, and experiences related to the radiotherapy mask and regaining normality. These data highlight issues of importance in the first year of living with head and neck cancer: impact of nutritional changes on the lives of patients, including weight loss, dysphagia, xerostomia and taste changes; debilitation from ongoing fatigue; unpreparedness for and distress from the radiotherapy mask; and attempts to maintain a normal life amidst the interference of symptoms.

CONCLUSION

Multitude of symptoms impact the patients' life, particularly nutritional symptoms and fatigue, and interfere with the patients' survivorship and quality of life. The changing nature of symptoms over the first year from diagnosis in head and neck cancer patients and the identified issues in the attempt to normalize their lives need to be incorporated more fully into the supportive care of head and neck cancer patients in order to improve their experience and enhance their survivorship.

Head and neck cancer patients' experiences of percutaneous endoscopic gastrostomy feeding: a Q-methodology study

Head and neck cancer patients are at high risk of malnutrition and its complications and therefore often undergo non-oral nasogastric or percutaneous endoscopic gastrostomy (PEG) nutrition support. However, there is little evidence that either approach is effective in this group. While one possible explanation for these findings relates to the relationship between artificial tube feeding and poor quality of life, there is little research that examines the patient's subjective experience of nutrition support. This study investigated the experiences of PEG tube feeding in head and neck cancer patients undergoing radical treatment. Conventional Q-methodology was used with 15 head and neck cancer patients, who rank-ordered 36 statements according to the extent to which these reflected their experiences of PEG tube feeding. The sorted statements were factor-analysed case-wise to provide clusters of similar experiences. Three perspectives emerged. Factor 1, labelled 'Constructive cognitive appraisal', focused around positive adaptation to, and acceptance of, PEG feeding. Factor 2, labelled 'Cognitive-affective dissonance', reflected ambivalence between cognitive acceptance and affective rejection of the PEG tube. Factor 3, labelled 'Emotion-focused appraisal', was characterised by tube-focused anxiety and fear. The findings broadly confirm Levanthal et al.'s Self-Regulatory Model of coping and support the need for genuine and individualised patient-centred nutritional care.
