Head and Neck Cancer Survivors' Experiences with Chronic Nutrition Impact Symptom Burden after Radiation: A Qualitative Study

Baseline weight recovery and mortality risk in head and neck cancer

BACKGROUND

As a surrogate of malnutrition, degree of weight loss and recovery from head and neck cancer (HNC) treatment is understudied. The influence of modifiable factors that affect weight, including speech/language pathology (SLP) and nutrition counseling, is also poorly defined. We characterize weight loss trends, baseline weight recovery (BWR), and the impact of interdisciplinary care on oncologic outcomes.

METHODS

Retrospective cohort study assessing 266 newly diagnosed patients with HNC who completed curative-intent radiation (definitive or adjuvant) between January 2016 to January 2022. Relevant treatment factors were analyzed using multivariable Cox regression models.

RESULTS

Altogether, 266 patients completed full-course radiation therapy (RT), encompassing definitive chemoRT (53.0%), surgery with chemoRT (18.4%), surgery with RT (17.7%), and RT alone (10.9%). Patient weight reached a nadir at median 3.0 months (IQR 3.0-11.3) after radiation, with a median weight loss of 12.6% (IQR 7.9-18.7). Notably, only 47.4% exhibited BWR. For those who recovered, median time to BWR was 10.5 months (IQR 3.0-24.0). On multivariable analysis, BWR by 6 months was significantly associated with overall survival (HR 0.28 [95% CI 0.10-0.76], p = 0.013), as was SLP consultation (HR 0.40 [95% CI 0.17-0.92], p = 0.031) and nutrition consultation (HR 0.34 [95% CI 0.13-0.89], p = 0.028).

CONCLUSION

A high proportion of patients with HNC fail to recover baseline weight after treatment; those that do can take longer than expected to return. Failure to recover baseline weight is associated with a notable decrease in survival. Similarly, SLP and nutrition consultation are independent, modifiable determinants correlated with outcomes, supporting the emphasis on multidisciplinary management. Measures to promote BWR may reduce mortality.

Postradiation trismus in head and neck cancer survivors: a qualitative study of effects on life, rehabilitation, used coping strategies and support from the healthcare system

PURPOSE

This study aimed to explore the experiences of head and neck cancer (HNC) survivors with postradiation trismus, specifically how oncological treatment affected their lives, rehabilitation, use of coping strategies, and healthcare experiences.

METHODS

A qualitative descriptive approach was used and semi-structured interviews of 10 HNC survivors with postradiation trismus were conducted 6-30 months after completing oncological treatment. The interviews were transcribed verbatim and analyzed by qualitative content analysis.

RESULTS

The analysis of interviews yielded four main categories: Bodily symptoms, Effects on life, Support from the healthcare system, and Strategies to handle life and symptoms. Participants reported ongoing problems with xerostomia, dysgeusia, eating, and limited physical fitness. Pain related to trismus was not a major issue in this cohort. Participants expressed limitations in their social lives due to their eating difficulties, yet a sense of thankfulness for life and overall satisfaction with the healthcare they received. Psychological and practical coping strategies developed by the participants were also revealed.

CONCLUSION

The results highlight areas of unmet need among HNC survivors that healthcare providers can target by establishing multi-professional teams dedicated to individualizing post-cancer rehabilitation care.

Investigating oral somatosensory perception and oral symptoms of head and neck cancer patients: insights on eating behaviour

PURPOSE

Sensory alterations and oral manifestations are prevalent among head and neck cancer (HNC) patients. While taste and smell alterations have been thoroughly investigated, studies on their oral somatosensory perception remain limited. Building upon our previous publication that primarily focused on objective somatosensory measurements, the present work examined self-reported sensory perception, including somatosensation and oral symptoms, in HNC patients and evaluated their link with eating behaviour.

METHODS

A cross-sectional study was conducted using self-reported questionnaires on sensory perception, oral symptoms, sensory-related food preference, and eating behaviour among HNC patients (n = 30). Hierarchical clustering analysis was performed to categorise patients based on their sensory perception. Correlations between oral symptoms score, sensory perception, sensory-related food preference, and eating behaviour were explored.

RESULTS

Two distinct sensory profiles of patients were identified: no alteration (n = 14) and alteration (n = 16) group. The alteration group showed decreased preference towards several sensory modalities, especially the somatosensory. Concerning eating behaviour, more patients in the alteration group agreed to negatively connotated statements (e.g. having food aversion and eating smaller portions), demonstrating greater eating difficulties. In addition, several oral symptoms related to salivary dysfunction were reported. These oral symptoms were correlated with sensory perception, sensory-related food preference, and eating behaviour.

CONCLUSION

This study presented evidence demonstrating that sensory alterations in HNC patients are not limited to taste and smell but cover somatosensory perception and are linked to various aspects of eating. Moreover, patients reported experiencing several oral symptoms. Those with sensory alterations and oral symptoms experienced more eating difficulties.

Qualitative Research Methodology and Applications: A Primer for the Otolaryngologist

OBJECTIVE

Qualitative and mixed methods methodology is becoming more commonplace in otolaryngology as the field strives to understand more complex concepts of the ear, nose, and throat. This methodology can have tremendous utility in studies directed at patient-centered care by offering practical insights and granular detail-directly from patients-which may not be realized by quantitative approaches.

METHODS

Narrative Review.

RESULTS

This review focuses on what questions can be answered by qualitative research, the basics of the underlying principals and different methodologies utilized, and describes the pearls, pitfalls, and rigor of qualitative research.

CONCLUSIONS

This understanding of qualitative inquiry is critical for the otolaryngologist to stay current on what is published and have the ability to include this in their research repertoire. Laryngoscope, 134:27-31, 2024.

Mapping the impact of malnutrition as defined by the Global Leadership Initiative on Malnutrition and nutrition impact symptoms on the possibility of returning to work after treatment for head and neck cancer

PURPOSE

This study aimed to investigate whether malnutrition or nutrition impact symptoms (NIS) affect the possibility of returning to work after treatment for head and neck cancer.

METHODS

Patients of working age with head and neck cancer were followed up from treatment initiation to 3 months (n = 238), 1 year (n = 182), and 2 years (n = 130) after treatment completion. The observed decrease in the number of patients over time was due to retirement, lack of follow-up, or death. Returning to work was dichotomised as yes or no. Malnutrition was diagnosed 7 weeks after treatment initiation using the Global Leadership Initiative on Malnutrition (GLIM) criteria. This time-point corresponds to the end of chemoradiotherapy or radiotherapy (with or without prior surgery), except for patients who underwent exclusive surgery. NIS were scored on a Likert scale (1-5) at each follow-up using the Head and Neck Patient Symptom Checklist© (HNSC©). Nonparametric tests were used to analyse the ability of patients with/without malnutrition and high/low NIS scores to return to work.

RESULTS

At 3 months, 1 year, and 2 years after treatment completion, 135/238 (56.7%), 49/182 (26.9%), and 23/130 (17.7%) patients had not returned to work. Patients with malnutrition at 7 weeks after treatment initiation were more likely to not return to work at 3 months than those without malnutrition, 70.5% compared to 47.1% (p < 0.001). At all three follow-up time-points, patients reporting high scores for a number of NIS had more often not returned to work, with this pattern being most distinct at 2 years.

CONCLUSION

Malnutrition according to the GLIM criteria at 7 weeks after treatment initiation and NIS assessed by the HNSC© at subsequent follow-ups were predictors of the return-to-work process after treatment for up to 2 years.

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

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

Meat texture modification for dysphagia management and application of hydrocolloids: A review

Dysphagia is a medical condition that describes the difficulty of swallowing food, and texture modified food (TMF) is the best intervention for dysphagia. The relevant guidelines to identify dysphagia food are provided by the International Dysphagia Diet Standardization Initiative (IDDSI). Developing texture modified meat is a challenging task due to its fibrous microstructure and harder texture. Various meat tenderization attempts are therefore evaluated in the literature. Meat texture modification for dysphagia is not just limited to tenderization but should be focused on safe swallowing attributes as well. The application of hydrocolloids for designing TMF has a major research focus as it is a cost-effective method and offers an opportunity for careful control. The present review focuses on the meat texture modification attempts that have been used in the past and present, with special attention to the use of hydrocolloids. Several studies have shown improvements in texture upon the addition of various hydrocolloids; however, few studies have attempted to develop texture modified meat for people with dysphagia. This area has to be further developed along with the sensory evaluations conducted with the dysphagia population, to validate the industrial application of hydrocolloids to TMF.

Pattern of nutritional status in node-negative versus node-positive head and neck cancer patients undergoing treatment: a prospective cohort study

PURPOSE

The aim of this study was to study the nutritional profile of node-negative and node-positive patients undergoing treatment for head and neck squamous cell cancer (HNSCC).

METHODS

This prospective cohort study was conducted between 2018 and 2020. Patients diagnosed with HNSCC, planned for treatment, were enrolled after written informed consent. In node-negative (N0) and node-positive (N +) cohorts of patients, nutritional status was determined using anthropometric measures and Subjective Global Assessment (SGA) scale pre-treatment, and during and after treatment. Statistical analysis was performed using SPSS version 22. Data was analyzed using parametric and non-parametric tests, and p value of 0.05 was considered significant.

RESULTS

In total, 161 patients were analyzed, 73 N0 and 88 N + cohorts. Pre-treatment, 9.6 to 20.4% patients in N0 and 23.9 to 32.8% patients in N + cohorts were malnourished. Incidence of malnutrition at completion of treatment was 40.8 to 52.5% overall, 20.5 to 41.1% N0, and 39.5 to 62.8% N + . Mean reduction in weight (11.1% ± 7.82 vs 6.26% ± 8.3, p = 0.000), mean reduction in BMI (2.57 ± 1.87 vs 1.29 ± 1.62, p = 0.000), median reduction in MUAC (2 cm vs 1 cm, p = 0.000), and median increase in SGA score (13 vs 6, p = 0.000) were higher in multi-modality as compared to those in a single-modality treatment. Similar findings were noted in N0 and N + cohorts.

CONCLUSION

As compared to N0, N + patients had higher burden of malnutrition at diagnosis, and more worsening of nutritional parameters during treatment. More decline in nutritional status was seen in patients receiving multi-modality as compared to single-modality treatment.

Pharyngeal tongue base augmentation for dysphagia therapy: A prospective case series in patients post head and neck cancer treatment

BACKGROUND

Dysphagia post head and neck cancer (HNC) multimodality treatment is attributed to reduced pharyngeal strength. We hypothesized that pharyngeal tongue base augmentation for dysphagia (PAD therapy) would increase pharyngeal pressures during swallowing thereby improving swallow symptoms.

METHODS

Adults with moderate-severe dysphagia post-HNC treatment had PAD therapy using a temporary filler (hyaluronic acid [HA]), with follow-up long-lasting lipofilling. Swallowing preprocedure and postprocedure was assessed with the Sydney Swallow Questionnaire (SSQ), High-Resolution Pharyngeal Manometry (HRPM), and Videofluoroscopic Swallowing Study (VFSS). Statistical comparison utilized paired tests.

RESULTS

Six participants (all male; median age 64 years [IQR 56, 71]) underwent PAD therapy at a median of 47 [IQR 8, 95] months post-treatment. SSQ scores reduced from baseline (mean 1069 [95%CI 703, 1434]) to post-HA (mean 579 [76, 1081], p > 0.05), and post-lipofilling (491 [95%CI 913, 789], p = 0.003, n = 4). Individual participants demonstrated reduced Swallow Risk Index, Bolus Presence Time, and increased Upper Esophageal Sphincter opening, but mesopharyngeal contractile pressures were unchanged. VFSS measures of aspiration, residue, and severity were unchanged.

CONCLUSIONS

Novel PAD therapy is safe and improves dysphagia symptoms. Biomechanical swallowing changes are suggestive of more efficacious bolus propulsion with conservative filler volume, but this was unable to resolve residue or aspiration measures.

Adherence to a priori-Defined Diet Quality Indices Throughout the Early Disease Course Is Associated With Survival in Head and Neck Cancer Survivors: An Application Involving Marginal Structural Models

No studies, to date, have scrutinized the role of a priori dietary patterns on prognosis following a head and neck squamous cell carcinoma (HNSCC) diagnosis. The purpose of this analysis was to evaluate the associations between adherence to six a priori defined diet quality indices (including AHEI-2010, aMED, DASH, and three low-carbohydrate indices) throughout the first 3 years of observation and all-cause and cancer-specific mortalities in 468 newly diagnosed HNSCC patients from the University of Michigan Head and Neck Specialized Program of Research Excellence (UM-SPORE). The dietary intake data were measured using a food frequency questionnaire administered at three annual time points commencing at study entry. Deaths and their causes were documented throughout the study using various data sources. Marginal structural Cox proportional hazards models were used to evaluate the role of diet quality, as a time-varying covariate, on mortality. There were 93 deaths from all causes and 74 cancer-related deaths adjudicated throughout the observation period. There was a strong inverse association between adherence to the AHEI-2010, all-cause mortality (HR_Q5–Q1:0.07, 95% CI:0.01–0.43, p_trend:0.04), and cancer-specific mortality (HR_Q5–Q1:0.15, 95% CI:0.02–1.07, p_trend:0.04). Other more modest associations were noted for the low-carbohydrate indices. In sum, higher adherence to the AHEI-2010 and a plant-based low-carbohydrate index throughout the first 3 years since diagnosis may bolster survival and prognosis in newly diagnosed patients with HNSCC.

Dietary Carotenoids in Head and Neck Cancer-Molecular and Clinical Implications

Head and neck cancer (HNC) is one of the most common cancers in the world according to GLOBCAN. In 2018, it was reported that HNC accounts for approximately 3% of all human cancers (51,540 new cases) and is the cause of nearly 1.5% of all cancer deaths (10,030 deaths). Despite great advances in treatment, HNC is indicated as a leading cause of death worldwide. In addition to having a positive impact on general health, a diet rich in carotenoids can regulate stages in the course of carcinogenesis; indeed, strong epidemiological associations exist between dietary carotenoids and HNS, and it is presumed that diets with carotenoids can even reduce cancer risk. They have also been proposed as potential chemotherapeutic agents and substances used in chemoprevention of HNC. The present review discusses the links between dietary carotenoids and HNC. It examines the prospective anticancer effect of dietary carotenoids against intracellular cell signalling and mechanisms, oxidative stress regulation, as well as their impact on apoptosis, cell cycle progression, cell proliferation, angiogenesis, metastasis, and chemoprevention; it also provides an overview of the limited preclinical and clinical research published in this arena. Recent epidemiological, key opinion-forming systematic reviews, cross-sectional, longitudinal, prospective, and interventional studies based on in vitro and animal models of HNC also indicate that high carotenoid content obtained from daily supplementation has positive effects on the initiation, promotion, and progression of HNC. This article presents these results according to their increasing clinical credibility.

The health risks of dysphagia for patients with head and neck cancer: a multicentre prospective observational study

It is well known that malnutrition is a frequent co-morbidity in cancer patients, especially in those with head and neck neoplasms. This may be due both to the presence of dysphagia symptoms and to the appearance of adverse effects on chemotherapy and / or radiotherapy. The aim of this retrospective observational multicentric study is to evaluate the nutritional status between dysphagia cancer patients and non-dysphagia cancer patients. Data from 60 patients were analysed, 31 of which without dysphagia and 29 with dysphagia. Results highlight that patients with dysphagia had higher involuntary body weight loss than non-dysphagia ones (p < 0.001). By analysing the entire population, it stands out a weight loss rate of 12 ± 9% compared to the usual weight was observed and a prevalence of moderate / severe malnutrition diagnosis of 53%. Furthermore, 76% of the population who manifested the symptom of dysphagia presented severe malnutrition already at the first visit, compared to 32% of non-dysphagia subjects.

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

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

Chronic Nutrition Impact Symptoms Are Associated with Decreased Functional Status, Quality of Life, and Diet Quality in a Pilot Study of Long-Term Post-Radiation Head and Neck Cancer Survivors

BACKGROUND

As a result of tumor location and treatment that is aggressive, head and neck cancer (HNC) survivors experience an array of symptoms impacting the ability and desire to eat termed nutrition impact symptoms (NISs). Despite increasing cancer survival time, the majority of research studies examining the impact of NISs have been based on clinical samples of HNC patients during the acute phase of treatment. NISs are often chronic and persist beyond the completion of treatment or may develop as late side effects. Therefore, our research team examined chronic NIS complications on HNC survivors' functional status, quality of life, and diet quality.

METHODS

This was a cross-sectional study of 42 HNC survivors who were at least 6 months post-radiation. Self-reported data on demographics, NISs, quality of life, and usual diet over the past year were obtained. Objective measures of functional status included the short physical performance battery and InBody© 270 body composition testing. NISs were coded so a lower score indicated lower symptom burden, (range 4-17) and dichotomized as ≤10 vs. >10, the median in the dataset. Wilcoxon rank sum tests were performed between the dichotomized NIS summary score and continuous quality of life and functional status outcomes. Diet quality for HNC survivors was calculated using the Healthy Eating Index 2015 (HEI-2015). Wilcoxon rank sum tests examined the difference between the HNC HEI-2015 as compared to the National Health and Nutrition Examination Survey (NHANES) data calculated using the population ratio method.

RESULTS

A lower NIS score was statistically associated with higher posttreatment lean muscle mass (p = 0.002). A lower NIS score was associated with higher functional (p = 0.0006), physical (p = 0.0007), emotional (p = 0.007), and total (p < 0.0001) quality of life. Compared to NHANES controls, HNC survivors reported a significantly lower HEI-2015 diet quality score (p = 0.0001).

CONCLUSIONS

Lower NIS burden was associated with higher lean muscle mass and functional, physical, emotional, and total quality of life in post-radiation HNC survivors. HNC survivors reported a significantly lower total HEI-2015 as compared to healthy NHANES controls, providing support for the hypothesis that chronic NIS burden impacts the desire and ability to eat. The effects of this pilot study were strong enough to be detected by straight forward statistical approaches and warrant a larger longitudinal study. For survivors most impacted by NIS burden, multidisciplinary post-radiation exercise and nutrition-based interventions to manage NISs and improve functional status, quality of life, and diet quality in this survivor population are needed.

Taste and Smell Function in Head and Neck Cancer Survivors

Survivors of head and neck squamous cell cancers (HNSCC) frequently complain of taste dysfunction long after radiation therapy is completed, which contradicts findings from most sensory evaluation studies that predict dysfunction should resolve few months after treatment. Therefore, it remains unclear whether taste and smell function fully recovers in HNSCC survivors. We evaluated HNSCC survivors (n = 40; age 63 ± 12 years, mean ± standard deviation) who received radiation therapy between 6 months and 10 years before recruitment and compared their responses to those of a healthy control group (n = 20) equivalent in age, sex, race, smoking history, and body mass index. We assessed regional (tongue tip) and whole-mouth taste intensity perception using the general Labeled Magnitude Scale and smell function using the University of Pennsylvania Smell Identification Test (UPSIT). To determine possible differences between groups in retronasal smell perception, we used solutions of sucrose with strawberry extract, citric acid with lemon extract, sodium chloride in vegetable broth, and caffeine in coffee and asked participants to rate perceived smell and taste intensities with and without nose clips. We found groups had similar UPSIT and taste intensity scores when solutions were experienced in the whole mouth. However, HNSCC survivors were less likely to identify low concentrations of bitter, sweet, or salty stimuli in the tongue tip relative to healthy controls. Our findings suggest persistent and subtle localized damage to the chorda tympani or to the taste buds in the fungiform papillae of HNSCC survivors, which could explain their sensory complaints long after completion of radiotherapy.

Patient and carer experiences of nutrition in cancer care: a mixed-methods study

PURPOSE

Evidence-based guidelines exist to guide health professionals and services about cancer nutrition care; however, the views of cancer patients and carers are not well understood. This study aimed to understand the experience and needs of cancer patients and carers regarding nutrition care across the care continuum.

METHODS

Using a mixed-methods approach, cancer patients and carers completed a cross-sectional online survey and focus groups. Participants were recruited through health services and cancer organisation consumer networks via email distribution lists, e-newsletters, and social media. Focus groups were audio-recorded, transcribed, and analysed using content analysis.

RESULTS

Of 165 survey respondents, only 51% (n=84) reported they talked to a health professional about their nutrition care at any time-point, and only 32% with a dietitian. The majority (84%) of patients and carers felt nutrition was important at one or more time-points in their cancer path, indicating during and after cancer treatment the most important. However, perceived support from health professionals for nutrition care was deemed low at all time-points. Five focus groups were held (n=20; 16 patients, 2 carers, 2 both patients/carers) and five themes emerged: nutrition information, experiences and need; control over diet and nutrition; importance and value of nutrition; access to support; what optimal nutrition care looks like.

CONCLUSION

Patients and carers felt nutrition was important during their cancer path, but perceived support from health professionals for nutrition care was low. This study has highlighted patient and carer nutrition experiences that will inform development of a co-designed optimal cancer nutrition care pathway.
