Randomised controlled trial of early prophylactic feeding vs standard care in patients with head and neck cancer

A proposed framework for the implementation of head and neck cancer treatment at a new cancer center from a radiation oncology perspective

BACKGROUND

Establishing a new head and neck cancer (HNC) treatment center requires multidisciplinary team management and expertise. To our knowledge, there are no clear recommendations or guidelines in the literature for the commencement of HNC radiation therapy (RT) at a new cancer center. We propose a novel framework outlining the necessary components required to set-up a new radiation therapy HNC treatment.

METHODS

We reviewed the infrastructure and methodology in the commencement of HNC radiation therapy in our cancer care center and invited several external, experienced metropolitan head and neck radiation oncologists to develop a novel consensus guideline that may be used by new RT centers to treat HNC. Recommendations were presented to our internal and external staff specialists using a survey questionnaire with ratings utilized to determine consensus using pre-defined thresholds as per the American Society of Clinical Oncology Guidelines Methodology Manual.

CONCLUSION

This consensus recommendation aims to improve RT utilization whilst advocating for optimal patient outcomes by presenting a framework for new radiation therapy centers ready to step up and manage the treatment of head and neck cancer patients. We propose these evidence-based consensus guidelines endorsed by external HNC radiation oncologists.

The Effect of Hospital-Based Liquid Diet and Commercial Formulas on Laboratory Parameters and Postoperative Complications in Patients with Head and Neck Cancer

Background: Patients with head and neck cancer (HNC) are at high risk of malnutrition. The aim of this study was to compare the effect of polymeric formulas available commercially and a high-protein liquid diet prepared in the hospital on laboratory parameters and postoperative complications in patients undergoing surgery for HNC. Methods: This single-center retrospective study included 149 patients who underwent surgery for HNC between 2008 and 2017. The following data were collected: patient and tumor characteristics, postoperative complications, and laboratory parameters measured at baseline and after surgery, including creatinine, alanine transaminase (ALT), aspartate transaminase (AST), and blood glucose levels. Correlations between the duration of enteral nutrition and blood parameters were assessed. Results: After surgery, patients receiving commercial formulas had lower creatinine and blood glucose levels and higher ALT and ASP levels than those on the hospital-based diet. The longer duration of feeding with commercial formulas before surgery was associated with enhanced preoperative levels of ALT and ASP and with lower postoperative blood glucose. Patients on the hospital-based diet had a higher rate of postoperative complications than those receiving commercial formulas (16.1% vs. 3.3%). Conclusions: There were no clinically important differences in blood parameters among patients with HNC depending on the type of preparations used for enteral feeding. However, increased levels of liver enzymes in patients fed with commercial formulas were notable. The early initiation of enteral nutrition before surgery helped achieve normal blood glucose levels after surgery. The use of commercial preparations contributed to reducing the number and incidence of postoperative complications.

Nutrition outcomes and treatment toxicities in patients with head and neck cancer receiving helical intensity-modulated radiotherapy

BACKGROUND

Helical intensity-modulated radiotherapy (H-IMRT) provides excellent limitation of dose to tissues not requiring treatment, although acute toxicity still occurs. The present study aimed to determine how treatment-related acute toxicities affect nutrition outcomes in patients with head and neck cancer.

METHODS

A prospective observational study was conducted in 194 patients undergoing curative intent H-IMRT with or without other treatment modalities. Weight outcomes (kg) and acute toxicity and dysphagia data were collected during treatment using Common Toxicity Criteria for Adverse Effects (CTCAE), version 4.0.

RESULTS

Significant weight loss (> 10%) was observed in 30% of high nutritional risk patients and 7% of low nutritional risk patients. Nausea, adjusted for baseline dysphagia, in high nutritional risk patients and nausea, dysphagia and pharyngeal mucositis in low nutritional risk patients were significant factors in explaining the percentage loss in baseline weight to treatment completion.

CONCLUSIONS

Significant weight loss remains an issue during treatment, despite improvements in radiotherapy technology and high-level multidisciplinary care.

The Effect of Nasogastric Feeding after Surgery in Patients with Head and Neck Cancers - Retrospective Single Center Experience

This study aimed to assess clinical factors that could predict the need for nasogastric feeding after surgery in patients with head and neck cancer (HNC) and evaluate the effect of tube feeding on selected laboratory parameters.This single-center retrospective study included 153 patients who underwent surgery for HNC. Data on patient and tumor characteristics were collected, along with laboratory measurements. Logistic regression was used to identify the predictors of the need for nasogastric feeding. Laboratory parameters were compared between patients who required nasogastric feeding vs those who did not.Nasogastric feeding was required in 90 patients (59%). Significant predictors of nasogastric feeding in HNC patients after surgery, which were revealed by univariate regression analysis, included low body mass index (odds ratio [OR] = 0.84), squamous cell carcinoma histology (OR = 8.05), T2 tumor stage (OR = 2.27), red blood cell count (M/µL) (OR = 0.44), hemoglobin levels (g/dL) (OR = 0.80), and mean corpuscular volume (fL) (OR = 1.10). Multivariate analysis showed that low BMI (OR = 0.87) and red blood cell count (M/µL) (OR = 0.32) were prognostic factors for nasogastric feeding. A significant percentage increase in white blood cell count from admission to discharge was noted in patients who required nasogastric feeding vs those who did not (p = 0.003).Determining factors that predict the need for nasogastric feeding in HNC patients after surgery may support more personalized treatment planning to optimize clinical outcomes.

Clinical Practice Guidelines for Oropharyngeal Dysphagia

OBJECTIVE

Dysphagia is a common clinical condition characterized by difficulty in swallowing. It is sub-classified into oropharyngeal dysphagia, which refers to problems in the mouth and pharynx, and esophageal dysphagia, which refers to problems in the esophageal body and esophagogastric junction. Dysphagia can have a significant negative impact one's physical health and quality of life as its severity increases. Therefore, proper assessment and management of dysphagia are critical for improving swallowing function and preventing complications. Thus a guideline was developed to provide evidence-based recommendations for assessment and management in patients with dysphagia.

METHODS

Nineteen key questions on dysphagia were developed. These questions dealt with various aspects of problems related to dysphagia, including assessment, management, and complications. A literature search for relevant articles was conducted using Pubmed, Embase, the Cochrane Library, and one domestic database of KoreaMed, until April 2021. The level of evidence and recommendation grade were established according to the Grading of Recommendation Assessment, Development and Evaluation methodology.

RESULTS

Early screening and assessment of videofluoroscopic swallowing were recommended for assessing the presence of dysphagia. Therapeutic methods, such as tongue and pharyngeal muscle strengthening exercises and neuromuscular electrical stimulation with swallowing therapy, were effective in improving swallowing function and quality of life in patients with dysphagia. Nutritional intervention and an oral care program were also recommended.

CONCLUSION

This guideline presents recommendations for the assessment and management of patients with oropharyngeal dysphagia, including rehabilitative strategies.

Prophylactic versus reactive feeding approach in patients undergoing adjuvant radiation therapy for oral cavity squamous cell carcinoma: A propensity score matched-pair analysis

BACKGROUND

To assess the efficacy of prophylactic versus reactive feeding strategy in oral cavity squamous cell carcinoma (OCSCC) patients receiving adjuvant radiation therapy (RT).

METHODS

This was a post hoc analysis of patients of OCSCC enrolled in a randomized trial comparing three adjuvant strategies. In this trial, till 2010, a prophylactic feeding approach was followed for all patients. Since January 2011, a reactive feeding approach was followed.

RESULTS

Two hundred and sixty-eight in each cohort (total n = 526) were eligible for analysis after propensity score matching. At 6 weeks post-RT completion, the median weight loss in the prophylactic versus reactive cohort was 5 versus 3 kg, p = 0.002. At all other time points until 1 year, the median weight loss was lesser in reactive than in the prophylactic cohort.

CONCLUSIONS

A reactive feeding tube approach should be preferred for OCSCC receiving adjuvant RT.

Impact of sarcopenia and myosteatosis on survival outcomes for patients with head and neck cancer undergoing curative-intent treatment

Malnutrition and sarcopenia are prevalent in patients with head and neck squamous cell carcinoma (HNSCC). Pre-treatment sarcopenia and adverse oncological outcomes in this population are well described. The impact of myosteatosis and post-treatment sarcopenia is less well known. Patients with HNSCC (n = 125) undergoing chemoradiotherapy, radiotherapy alone and/or surgery were assessed for sarcopenia and myosteatosis, using cross-sectional computed tomography (CT) imaging at the third lumbar (L3) vertebra, at baseline and 3 months post-treatment. Outcomes were overall survival (OS) at 12 months and 5 years post-treatment. One hundred and one participants had a CT scan evaluable at one or two time points, of which sixty-seven (66 %) participants were sarcopenic on at least one time point. Reduced muscle attenuation affected 93 % (n = 92) pre-treatment compared with 97 % (n = 90) post-treatment. Five-year OS favoured those without post-treatment sarcopenia (hazard ratio, HR 0·37, 95 % CI 0·16, 0·88, P = 0·06) and those without both post-treatment myosteatosis and sarcopenia (HR 0·33, 95 % CI 0·13, 0·83, P = 0·06). Overall, rates of myosteatosis were high at both pre- and post-treatment time points. Post-treatment sarcopenia was associated with worse 5-year OS, as was post-treatment sarcopenia in those who had myosteatosis. Post-treatment sarcopenia should be evaluated as an independent risk factor for decreased long-term survival post-treatment containing radiotherapy (RT) for HNSCC.

Enteral nutrition support and treatment toxicities in patients with head and neck cancer receiving definitive or adjuvant helical intensity-modulated radiotherapy with concurrent chemotherapy

BACKGROUND

Enteral nutrition (EN) is often required in patients with head and neck cancer (HNSCC); however, initiation criteria is limited or inconsistent. This study aimed to describe the relationship of treatment toxicities and requirement for EN and investigate toxicity and baseline characteristics association with EN duration.

METHODS

Acute toxicities and baseline characteristics were collected from patients with HNSCC (n = 110) undergoing H-IMRT. Percentage EN contributing to estimated requirements and EN duration were measured.

RESULTS

The threshold for patients needing ≥50% of estimated requirements via EN increased from week 3 to 4 for grade ≥2 oral/pharyngeal mucositis, dysgeusia, thick saliva and nausea, and for grade 3 dysphagia. Patients with grade 2-3 dysphagia had a reduced risk of ceasing EN compared to those with grade 0-1 dysphagia.

CONCLUSIONS

Using acute toxicities in clinical practice may be a useful tool to inform prompt initiation of EN prior to decline in nutritional status and anticipate EN duration.

Systematic Review of Nutrition Interventions to Improve Short Term Outcomes in Head and Neck Cancer Patients

Head and neck cancer (HNC) is associated with high rates of malnutrition. We conducted a systematic review and descriptive analysis to determine the effects of nutrition interventions on the nutrition status, quality of life (QOL), and treatment tolerance of HNC patients. PubMed, Web of Science, and Embase were searched to include all potentially relevant studies published between 2006-2022. Meta-analysis was not conducted due to heterogeneity of study designs and outcomes reported. Studies were categorized as nutrition interventions: (1) with oral nutrition supplements (ONS) and medical nutrition therapy (MNT) delivered by an RD; (2) with enteral nutrition (EN) support and MNT delivered by an RD; (3) with motivational interviewing and no ONS or EN; and (4) with ONS and no RD. Seven articles met inclusion criteria. Studies measured outcomes from immediately following treatment to 12 months post-treatment. Interventions resulted in benefits to lean mass/weight maintenance (three studies), QOL (two studies), nutrient intake adequacy (one study) and treatment tolerance (two studies). Nutrition counseling by a registered dietitian leads to improved nutrition status and QOL. Further research is needed to determine best practices related to timing of initiation, duration of nutrition intervention, as well as frequency of dietitian follow-up.

Prevalence and Impact of Computed Tomography-Defined Sarcopenia on Survival in Patients with Human Papillomavirus-Positive Oropharyngeal Cancer: A Systematic Review

Sarcopenia is a known independent prognostic factor for decreased survival in patients with head and neck cancer; yet, its importance for the growing number of younger patients diagnosed with human papillomavirus (HPV)-positive oropharyngeal carcinoma (OPC+) has not been established. This systematic literature review aimed to determine the prevalence and impact of computed tomography (CT)-defined sarcopenia on survival outcomes for adult OPC+ patients (>18 y) undergoing any treatment modality. Prospective studies were searched using PubMed, Embase, CENTRAL, CINAHL, and Web of Science up until and including February 2022. Bias was assessed using the Quality In Prognosis Studies (QUIPS) tool, and certainty of evidence using the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) system. In total, 9 studies (total pooled OPC+ patients, n  = 744) were identified and included in this review; 2 at low, 6 at moderate, and 1 at high risk of bias. All studies varied in sarcopenia assessment methods and skeletal muscle index threshold cutoff values. These studies demonstrated the cumulative prevalence of sarcopenia for OPC+ patients to be 42.9% (95% CI: 37.8%, 47.9%). While overall survival (3 studies, n = 253) and progression-free survival (1 study, n = 117) was lower in sarcopenic OPC+ patients, this was not statistically significant. GRADE certainty of evidence for impact of pretreatment sarcopenia on overall survival was low and progression-free survival was very low. Although these studies showed there to be a high prevalence of pretreatment sarcopenia in patients with OPC+, which may decrease survival, the impact on progression-free survival is very uncertain. Further, high-quality research utilizing consistent sarcopenia definitions and assessment methods that are conducted specifically in OPC+ is required to strengthen evidence certainty and determine if sarcopenia is an independent prognostic factor for this population.

Prophylactic feeding tube placement for squamous cell carcinoma of the head and neck

BACKGROUND

Percutaneous endoscopic gastronomy (PEG) tubes are commonly used to administer enteral nutrition during head and neck cancer (HNC) treatment. However, the benefits of placing a prophylactic feeding tube (PFT; prior to radiotherapy [RT]) or reactive feeding tube (RFT, after RT initiation) are unclear. We sought to compare survival, body mass trends, and hospitalization rates between strategies.

METHODS

We conducted a retrospective cohort study of 11,473 Veterans with stages III-IVC HNC treated with chemoradiotherapy. Patients with PEG tube placement within 30 days prior to treatment initiation (PFT) were compared to all other patients (non-PFT) or patients with PEG tube placement within 3 months after treatment initiation placement (RFT). We compared survival, longitudinal body mass changes, and hospitalization rates for PFT versus non-PFT or RFT patients in propensity score (PS)-matched Cox regression models.

RESULTS

3,186 (28 %) patients received PFT and 8,287 (72 %) were non-PFT, of which 1,874 (23 %) received RFT. After PS-matching, there were no significant differences in overall survival (HR 0.97, 95 % CI 0.92-1.02), HNC-specific survival (HR 0.98, 95 % CI 0.92-1.09), change in BMI (p = 0.24), or hospitalization rates between PFT and non-PFT groups. Significant differences in hospitalization rates between PFT and RFT groups persisted after PS-matching (-0.11 hospitalizations/month), but no differences were found for other outcomes.

CONCLUSION

Timing of PEG tube placement in Veterans with HNC was not associated with any significant survival or body mass advantage. However, patients who received PFT had a lower hospitalization rate than those who received RFT.

Sarcopenia in head and neck cancer: A scoping review

OBJECTIVES

In those undergoing treatment for head and neck cancer (HNC), sarcopenia is a strong prognostic factor for outcomes and mortality. This review identified working definitions and methods used to objectively assess sarcopenia in HNC.

METHOD

The scoping review was performed in accordance with Arksey and O'Malley's five-stage methodology and the Joanna Briggs Institute guidelines.

INFORMATION SOURCES

Eligible studies were identified using MEDLINE, Embase, Scopus, Cochrane Library, and CINAHL databases.

STUDY SELECTION

Inclusion criteria represented studies of adult HNC patients in which sarcopenia was listed as an outcome, full-text articles written in English, and empirical research studies with a quantitative design.

DATA EXTRACTION

Eligible studies were assessed using a proprietary data extraction form. General information, article details and characteristics, and details related to the concept of the scoping review were extracted in an iterative process.

RESULTS

Seventy-six studies published internationally from 2016 to 2021 on sarcopenia in HNC were included. The majority were retrospective (n = 56; 74%) and the prevalence of sarcopenia ranged from 3.8% to 78.7%. Approximately two-thirds of studies used computed tomography (CT) to assess sarcopenia. Skeletal muscle index (SMI) at the third lumbar vertebra (L3) (n = 53; 70%) was the most prevalent metric used to identify sarcopenia, followed by SMI at the third cervical vertebra (C3) (n = 4; 5%).

CONCLUSIONS

Currently, the most effective strategy to assess sarcopenia in HNC depends on several factors, including access to resources, patient and treatment characteristics, and the prognostic significance of outcomes used to represent sarcopenia. Skeletal muscle mass (SMM) measured at C3 may represent a practical, precise, and cost-effective biomarker for the detection of sarcopenia. However, combining SMM measurements at C3 with other sarcopenic parameters-including muscle strength and physical performance-may provide a more accurate risk profile for sarcopenia assessment and allow for a greater understanding of this condition in HNC.

Oral Dysfunction in Patients with Oral Cancer Could Occur Before Treatment and Require Early Nutritional Improvement: A Cross-Sectional Study

Patients with oral cancer have poor nutritional status before treatment. However, there have been no reports of the detailed evaluation of preoperative oral function in patients with oral squamous cell carcinoma (OSCC). Therefore, this study aimed to evaluate the preoperative oral function of patients with OSCC and examine the relationship with nutritional status. Oral function measurements (microorganisms, oral dryness, occlusal force, tongue pressure, masticatory function, Eating Assessment Tool, and Postoperative Oral Dysfunction Scale) and Mini Nutritional Assessment-Short Form (MNA-SF) data were collected from 51 patients with OSCC (men: 37, women: 14, mean age: 72.1 years) who visited the Shimane University Hospital, Department of Oral and Maxillofacial Surgery, from September 2019 to September 2021. The tongue was the most prevalent primary gingiva site [22 patients (43.1%)], and 36 patients (70.6%) had advanced cancer. Comparisons between nutritional status and each related factor revealed significant differences in the number of individuals in the household, cancer stage, presence of pulmonary disease, number of teeth, microorganisms (grade), and masticatory function (mg/dL) (p < 0.05). Multiple regression analysis using the total MNA-SF score as the dependent variable with adjustment for confounding factors showed significant association between oral dryness and tongue pressure (p < 0.05). No significant association was found for the Eating Assessment Tool or Postoperative Oral Dysfunction scale. Patients with OSCC may have decreased oral function because of the tumor at the time of diagnosis, which causes a decline in nutritional status. Preoperative interventions are necessary to improve nutrition based on the state of oral function.

The changing face of head and neck cancer: are patients with human papillomavirus-positive disease at greater nutritional risk? A systematic review

PURPOSE

Human papillomavirus (HPV) is now the primary cause of oropharyngeal head and neck cancer (OPC) worldwide; yet limited research has examined the effect of HPV-positive status (OPC+) on nutrition outcomes. This study aims to determine the impact of HPV status on nutritional outcomes for adult patients with OPC undergoing any treatment modality.

METHODS

A systematic literature review was conducted up to and including July 2021 of PubMed, Embase, CENTRAL, CINAHL, and Web of Science to identify studies conducted in adults (>18 years) with known OPC reporting on any outcome(s) related to nutrition, according to HPV status (OPC+ versus OPC-). Bias was assessed using QUIPS tool, with certainty of evidence assessed using GRADE system.

RESULTS

Six studies (total n = 635) all at moderate-high risk of bias were included. Three studies reported on weight change (n = 255), three feeding tube dependency (n = 380), three feeding tube timing of placement (prophylactic or reactive) and/or utilisation (n = 255), two nutritional (energy and/or protein) intake (n = 230), and one nutritional status (n = 83). Patients with OPC+ may experience greater weight loss, may have higher utilisation of reactive feeding tubes (both GRADE low certainty, downgraded due to serious bias and imprecision), and may have lower feeding tube dependency rates (GRADE low certainty, downgraded due to serious bias and inconsistency) versus OPC- . It is uncertain whether nutritional intake and nutritional status differed between populations (GRADE very low certainty, downgraded due to serious bias and very serious imprecision).

CONCLUSION

Further, high-quality research is needed to understand optimal nutritional care practices for patients with OPC + to achieve positive health outcomes into survivorship.

Oral functional impairment may cause malnutrition following oral cancer treatment in a single-center cross-sectional study

Oral dysfunction and dysphagia after oral cancer treatment are linked to altered nutritional status. We aimed to identify specific oral functions related to nutritional status. We conducted a cross-sectional study from September 2019 to December 2021, recruited 75 participants (median age: 72.0 years), including 52 males and 23 females, collected background data, and evaluated oral function. The Mini Nutritional Assessment-Short Form (MNA-SF) scores were divided into three groups (normal nutritional status, at risk of malnutrition, and malnourished), and a multi-group comparison was conducted for each oral function measurement (microorganisms, oral dryness, occlusal force, tongue pressure, masticatory function, and Eating Assessment Tool [EAT-10]). The primary tumor site was the tongue in 31 patients (41.3%), gingiva in 30 (40.0%), and others in 14 (18.7%). Multiple comparisons revealed significant differences in occlusal force, tongue pressure, masticatory function, and EAT-10 levels, categorized as Type I (Transport type) and Type III (Occlusion type) postoperative oral dysfunctions, between each MNA-SF group. Multiple regression analysis showed a statistically significant association with MNA-SF in terms of masticatory function and EAT-10 levels, categorized as Type I. Type I and Type III are risk factors for malnutrition, confirming that different types of postoperative oral dysfunction require unique nutritional guidance.

Predictors of gastrostomy tube placement in patients with head and neck cancer undergoing resection and flap-based reconstruction: systematic review and meta-analysis

BACKGROUND

Nutritional status may be impaired in patients with head and neck cancer undergoing surgical treatment, often necessitating gastrostomy tube (G-tube) placement. Identifying which patients will require a G-tube remains a challenge. This study identifies predictors of G-tube requirement in patients undergoing tumor resection and reconstruction with pedicled or free flaps.

METHODS

Systematic review of the PubMed, Cochrane, and Scopus databases was performed of English language articles, discussing risk factors of perioperative G-tube placement among patients >18 years. Data on patient, tumor, and treatment factors, as well as need for G-tube, were collected. Univariable meta-analysis was conducted to identify predictors for G-tube placement.

RESULTS

Eleven studies (1,112 patients) met inclusion criteria. Overall pooled prevalence of postoperative G-tube placement was 25%. Patients with advanced cancer stage IV/recurrence were more likely to require a G-tube (OR 2.81 [CI 1.03-7.69]; p<0.05), as were those who had undergone preoperative radiation (OR 3.55 [CI 2.03-6.20], p<0.05). Reconstruction with a radial forearm free flap was associated with a lower need for G-tube versus rectus abdominis (OR 0.25 [CI 0.08-0.83], p=0.02) and latissimus dorsi flap (OR 0.21 [CI 0.04-1.09], p=0.06). There was no difference in G-tube placement between those receiving pedicled flaps versus free flaps (OR 1.54 [CI 0.38-6.20], p=0.54).

CONCLUSIONS

Among patients with head and neck cancer undergoing resection with immediate pedicled or free flap reconstruction, advanced tumor stage and history of prior radiation therapy are associated with increased likelihood of G-tube placement. More randomized controlled trials are needed to develop a decision-making algorithm.

Managing Cachexia in Head and Neck Cancer: a Systematic Scoping Review

Introduction

Patients with head and neck cancer (HNC) are usually confronted with functional changes due to the malignancy itself or its treatment. These factors typically affect important structures involved in speech, breathing, chewing, swallowing, and saliva production. Consequently, the intake of food will be limited, which further contributes to loss of body weight and muscle mass, anorexia, malnutrition, fatigue, and anemia. This multifactorial condition can ultimately lead to cancer cachexia syndrome. This study aims to examine the treatment of cachexia in HNC patients.

Methods

We systematically searched OvidMedline, PubMed, Scopus, and Web of Science for articles examining the treatment of cachexia in HNC.

Results

A total of nine studies were found, and these suggested interventions including nutritional, pharmacologic, therapeutic exercise, and multimodal approaches. The nutritional intervention includes essential components such as dietary counseling, oral nutritional supplements, and medical nutritional support. Individualized nutritional interventions include oral, enteral (feeding tubes i.e., percutaneous endoscopic gastrostomy [PEG], nasogastric tube [NGT]) and parenteral nutrition. The pharmacologic interventions aim at increasing the appetite and weight of cachectic patients. Therapeutic exercise and increased physical activity can help to enhance the synthesis of muscle protein, reducing inflammation and the catabolic effects of cachexia syndrome.

Conclusion

Owing to the multifactorial nature of this syndrome, it is expected that the management approach should be multi-interventional. Early implementation of these interventions may help to improve survival and quality of health and life of cachectic HNC patients.

Tube feeding in head and neck cancer patients undergoing chemoradiotherapy: a systematic review

BACKGROUND

Head and neck cancer patients are frequently malnourished at the time of diagnosis and prior to the beginning of treatment. In addition, chemo-radiotherapy (CRT) causes or exacerbates symptoms, such as alteration or loss of taste, mucositis, xerostomia, fatigue, nausea, and vomiting, with consequent worsening of malnutrition. If obstructing cancer and/or mucositis interfere with swallowing, enteral nutrition should be delivered by a nasogastric tube (NGT) or percutaneous endoscopic gastrostomy (PEG).

AIM

To revise the studies comparing NGT and PEG in terms of nutritional outcomes, survival, hospitalizations, number of interruptions of radiotherapy, quality of life, swallowing function.

RESULTS

A total of 250 publications were identified via electronic databases. After screening the titles, abstracts and full texts, 26 manuscripts that met the inclusion criteria were included for analysis. We divided the analysis in two sections: 1) comparison of enteral nutrition through NGT or PEG and 2) comparison of reactive PEG (R-PEG) and prophylactic PEG (P-PEG).

RESULTS

Both PEG and NGT are an effective method of providing nutritional support during chemoradiotherapy for head and neck cancer. They are essentially comparable in terms of nutritional outcomes, number of radiotherapy interruptions, survival, and quality of life, whereas swallow function seems better with NGT. PEG may be associated with major complications such as exit site infection, malfunction, leakage, pain, and pulmonary infection and higher costs. Nevertheless, NGT dislodged more often, patients find it more inconvenient, may cause aspiration pneumonia and PEG has advantages over NGT of enhanced mobility and improved cosmesis. P-PEG and R-PEG are essentially similar in terms of nutritional outcomes, number of interruptions of radiotherapy, and survival. Conflicting results have been reported about quality of life.

CONCLUSION

PEG is not better than NGT in terms of nutritional, oncologic, and quality of life outcomes. Prophylactic feeding through NGT or PEG, compared to reactive feeding, does not offer significant advantages in terms of nutritional outcomes, interruptions of radiotherapy and survival. However, the number of prospective randomized studies on this topic is much limited and consequently definitive conclusions cannot be drawn. Overall, it seems that further adequate prospective, randomized studies are needed to define the better nutritional intervention in head and neck cancer patients undergoing chemoradiotherapy.

Quality of Life of Cancer Patients Receiving Enteral Nutrition: A Systematic Review of Randomized Controlled Trials

Most studies confirm the beneficial effects of enteral nutrition on the quality of life, but some studies indicate an inverse association and its detrimental impacts. However, there are insufficient data on the effects of enteral nutrition on the quality of life of cancer patients. This systematic review aimed to describe the influence of applied enteral nutrition on the quality of life of cancer patients, based on the results of randomized controlled trials. It was registered in the PROSPERO database (CRD42021261226) and conducted based on the PRISMA guidelines. The searching procedure was conducted using the PubMed and Web of Science databases, as well as Cochrane Library, and it included studies published until June 2021. It was conducted to select randomized controlled trials assessing the influence of enteral nutrition (compared with the other model of nutrition) on the quality of life of cancer patients. A general number of 761 records were screened and a final number of 16 studies were included in the systematic review. The studies were included and assessed by two independent researchers, while the risk of bias was analyzed using the Newcastle–Ottawa Scale (NOS). Studies compared patients treated with and without enteral nutrition, patients treated with various methods of enteral nutrition or with enteral diets of various content, as well as patients treated with enteral and parenteral nutrition. Within the included studies, the majority were conducted in patients with cancers located in various parts of the body, or diverse areas within the gastrointestinal system, while some studies were conducted in specific populations of patients with a defined cancer location—esophagus, stomach, or ovary. The duration of applied enteral nutrition within the included studies was diversified—from two weeks or less to half a year or even more. The vast majority of studies used well-known and validated tools to assess the quality of life, either developed for a specific group of head/neck, esophagus/stomach, and ovary cancer patients or developed for more general patient populations. Most studies concerning patients treated with and without enteral nutrition supported applying enteral nutrition, which was concluded in seven studies out of ten (including four studies with a low risk of bias). The other important observations to be emphasized—formulated based on the studies with a low risk of bias—presented the role of oral supportive nutrition guided by a dietitian, as well as the beneficial role of enteral and parenteral nutrition, combined. In spite of a relatively low number of randomized controlled trials assessing the influence of enteral nutrition on the quality of life of cancer patients, which should be considered as a limitation, the results were promising. Most studies supported the positive influence of enteral nutrition on the quality of life, either assessed based on the psychological measures of the quality of life or by considering the other potential determinants (e.g., malnutrition, complications, etc.). Taking this into account, enteral nutrition should be applied whenever possible, both to prevent and treat malnutrition in cancer patients. However, considering the limited number of studies conducted so far, further research conducted in homogenic populations of patients is necessary.

Comparison of prophylactic percutaneous endoscopic gastrostomy with reactive enteral nutrition in patients with head and neck cancer undergoing radiotherapy or chemoradiotherapy: A systematic review

BACKGROUND & AIMS

Nutrition support is frequently indicated in patients with head and neck cancer (HNC). However, the optimal timing of enteral tube placement and feeding commencement is unknown. This review aims to compare the outcomes for patients with HNC undergoing curative intent radiotherapy (RT) or chemoradiotherapy (CRT) receiving either prophylactic percutaneous endoscopic gastrostomy (pPEG) tube placement/feeding or reactive enteral nutrition (rEN).

METHODS

A literature search was conducted in March 2020 across PubMed, CINAHL, Embase, Web of Science, and Scopus. Randomized controlled trials (RCTs) of patients (≥18 years) with HNC who had received either pPEG or rEN were included. Outcomes examined were weight change, nutritional status, body mass index, treatment interruptions, quality of life (QoL), disease-free survival and overall survival. Study quality and certainty of evidence were assessed using the Cochrane Risk-of-bias Tool for Randomized Trials Version 2 and the Grading of Recommendations Assessment, Development and Evaluation system, respectively.

RESULTS

Five studies (three RCTs) (n = 298) were included and definitions of pPEG and rEN were heterogenous. pPEG was associated with a clinically important reduction in short-term critical weight loss (>10% weight loss), and significantly improved short-term QoL in patients with HNC. The timing of nutrition support commencement had no effect on all other outcomes. The overall certainty of evidence was 'moderate' for: nutritional status; treatment interruptions; short-term QoL; disease-free survival; and 'low' for all other outcomes.

CONCLUSIONS

Patients with HNC undergoing RT or CRT receiving pPEG tube feeding/placement were less likely to experience short-term critical weight loss and have improved short-term QoL compared to rEN. Further well-designed RCTs with consistent definitions of tube feeding protocols and the use of validated tools to evaluate nutritional status, will assist to increase the certainty of evidence and confirm the beneficial effects observed.

Evaluation of a novel pre-treatment model of nutrition care for patients with head and neck cancer receiving chemoradiotherapy

AIMS

Weight loss and malnutrition occur frequently in patients with head and neck cancer and are associated with reduced survival. This pragmatic study aimed to determine the effect of a novel pre-treatment model of nutrition care on nutrition outcomes for patients with head and neck cancer receiving chemoradiotherapy.

METHODS

This health service evaluation consisted of an evaluation of the new model of care implementation (Phase 1) and an evaluation of patient outcomes (Phase 2) in pre- and post-implementation cohorts (n = 64 and n = 47, respectively). All Phase 2 patients received a prophylactic gastrostomy. The new model of care consisted of dietary counselling and commencement of proactive supplementary enteral nutrition via a prophylactic gastrostomy, in addition to normal oral intake, prior to treatment commencement. Nutrition outcomes were collected at baseline (pre-treatment) and 3 months post-radiotherapy completion.

RESULTS

The new model of care was successfully incorporated into practice with high referral (96.5%) and attendance (91.5%) rates to the counselling session, and high adherence rates to proactive tube feeding (80.9%). Patients in the post-implementation cohort had less weight-loss (1.2%; p = 0.338) and saw less of a decline in nutritional status compared to patients in the pre-implementation cohort (23% vs. 30%, respectively; p = 0.572), deemed clinically important. However, patients still experienced critical weight loss overall (mean 9.9%).

CONCLUSION

Pre-treatment nutrition care was feasible in standard clinical practice and demonstrated clinically relevant outcome improvements for patients. Future high-quality research is warranted to investigate further multidisciplinary strategies to attenuate weight-loss further, inclusive of patient-reported barriers and enablers to nutrition interventions.

The association of pretreatment low skeletal muscle mass with chemotherapy dose-limiting toxicity in patients with head and neck cancer undergoing primary chemoradiotherapy with high-dose cisplatin

Background

Low skeletal muscle mass (SMM) is an adverse prognostic factor for chemotherapy dose‐limiting toxicity (CDLT). In patients with locally advanced head and neck squamous cell carcinoma (HNSCC) undergoing chemoradiotherapy (CRT), low SMM is a predictor for CDLT. We aimed to validate these findings.

Methods

Consecutive LA‐HNSCC patients treated with primary CRT with high‐dose cisplatin were retrospectively included. SMM was measured on pre‐treatment CT‐imaging. A cumulative cisplatin dose below 200 mg/m² was defined as CDLT.

Results

One hundred and fifty three patients were included; 37 (24.2%) experienced CDLT, and 84 had low SMM (54.9%). Patients with low SMM experienced more CDLT than patients with normal SMM (35.7% vs. 10.1%, p < 0.01). Low SMM (OR 3.99 [95% CI 1.56–10.23], p = 0.01) and an eGFR of 60–70 ml/min (OR 5.40 [95% CI 1.57–18.65], p < 0.01) were predictors for CDLT.

Conclusion

Pre‐treatment low SMM is associated with CDLT in LA‐HNSCC patients treated with primary CRT. Routine SMM assessment may allow for CDLT risk assessment and treatment optimization.

Nutritional interventions in patients with head and neck cancer undergoing chemoradiotherapy: Current practice at the Dutch Head and Neck Oncology centres

Objective

To assess variations in nutritional interventions during chemoradiotherapy (CRT) among the Dutch Head and Neck Oncology centres (HNOCs).

Methods

An online questionnaire about nutritional interventions and dietetic practices was sent to 14 oncology dietitians of the HNOCs.

Results

The response rate was 93%. The number of scheduled dietetic consultations varied from two to seven during CRT. Most centres (77%) reported using a gastrostomy for tube feeding in the majority of patients. Gastrostomies were placed prophylactically upon indication (39%) or in all patients (15%), reactive (15%), or both (31%). For calculating energy requirements, 54% of the dietitians used the Food and Agriculture Organization/World Health Organization and United Nations University (FAO/WHO/UNU) formula and 77% uses 1.2–1.5 g/kg body weight for calculating protein requirements. Almost half of the centres (46%) reported to remove the gastrostomy between 8 and 12 weeks after CR. Most centres (92%) reported to end dietary treatment within 6 months after CRT.

Conclusion

This study shows substantial variation in dietetic practice, especially in the use of a gastrostomy for tube feeding, between the HNOCs. There is a need for concise dietetic guidelines.

An overview of percutaneous endoscopic gastrostomy tube placement in the intensive care unit

Critically ill patients are at increased risk for malnutrition as they often have underlying acute and chronic illness, stress related catabolism, decreased appetite, trauma and ongoing inflammation. Malnutrition is recognized as a leading cause of adverse outcomes, higher mortality, and increased hospital costs. Percutaneous endoscopic gastrostomy (PEG) tubes provide a safe and effective route to provide supplemental enteral nutrition to these patients. PEG placement has essentially replaced surgical gastrostomy as the modality of choice for longer term feeding in patients. This is a highly prevalent procedure with 160,000 to 200,000 PEG procedures performed each year in the United States. The purpose of this review is to provide an overview of current knowledge and practice standards with regards to placement of PEG tube in the Intensive Care Unit (ICU). When a patient is considered for a PEG tube, it is important to evaluate the treatment alternatives and identify the best option for each patient. In this review, we provide the advantages and disadvantages of various feeding modalities and devices. We review the indications and contraindications for PEG tube placement as well as the risks of this procedure. We then describe in detail the per-oral pull, per-oral push, and direct percutaneous techniques for PEG tube placement. Additionally, we review the feasibility of having interventional pulmonologists place PEG tubes in the ICU.

Evaluation of the agreement, adoption, and adherence to the evidence-based guidelines for the nutritional management of adult patients with head and neck cancer among Australian dietitians

AIM

Evidence-based guideline translation to practice can improve outcomes but is often impaired by poor implementation. This project aimed to evaluate the implementation of the Evidence-based guidelines for the nutritional management of adult patients with head and neck cancer among Australian dietitians providing clinical care to this population.

METHODS

A questionnaire was developed, with face and content validity confirmed by an expert panel (n = 13), to gauge participant perceptions of the guidelines against an implementation evaluation framework. Dietitians were identified through Dietitians Australia and by contacting experts in the field. Eligibility was determined by questionnaire completion and prior guideline awareness. Responses were provided using a 5-point Likert scale. Results were analysed using descriptive statistics; with inferential analysis to determine if demographic information could reveal trends in guideline use and perception.

RESULTS

Of the 43 initial respondents, n = 28 completed the questionnaire, with n = 24/28 (86%) meeting full eligibility criteria for analysis. Median (range) scores for all four domains were high: awareness (4.0 [3.2-4.8]), agreement (4.4 [4.1-4.7]), adoption (3.5 [3.1-3.9]), and adherence (4.3 [4.1-4.9]). However, perception of guideline awareness and use among multidisciplinary team colleagues was low (mean 3.2/5.0 and 3.1/5.0, respectively). Dietitians with <10 years' experience had significantly higher perceptions of the guidelines' ability to positively influence practice; support evidence-based practice; and enhance dietitian credibility (P = 0.04) vs dietitians with ≥10 years' experience.

CONCLUSION

Dietitians demonstrated high rates of guideline implementation and positive perceptions for its use in clinical practice. Future implementation strategies and evaluation should expand to engage the wider multidisciplinary team and more experienced clinicians.

Blenderized food tube feeding in patients with head and neck cancer

Background

Patients with headand neck cancer (HNC) are at high risk for malnutrition before and during chemoradiation treatment. Many will also require tube feeding to address declines in energy intake, weight, and quality of life (QOL) caused by the impact of treatment on gastrointestinal (GI) symptoms. Blenderized tube feeding (BTF) may ameliorate these adverse conditions.

Methods

In this open‐label, prospective pilot study, 30 patients with HNC who required feeding tube placement were recruited to switch from standard commercial formula after 2 weeks to a commercially prepared BTF formula. Weight, body mass index (BMI), GI symptoms, and QOL scores were tracked for 6 weeks from the first week of feeding tube placement.

Results

Of the 16 patients who completed the 6‐week assessment period, weights and BMI scores for 15 patients trended upward. For most patients, QOL and oral intake increased and GI symptoms decreased over the 6‐week period, particularly during weeks 3 and 4, when the impact of treatment is particularly exacting on patients with HNC.

Conclusion

BTF effectively mitigated weight loss, GI symptoms, QOL scores, and total energy intake in this group of patients with HNC who received tube feeding for 6 weeks.

Intensity Modulated Proton Beam Therapy versus Volumetric Modulated Arc Therapy for Patients with Nasopharyngeal Cancer: A Propensity Score-Matched Study

(1) Background: We compared the outcomes of patients with nasopharyngeal carcinoma treated with IMPT and VMAT. (2) Methods: We performed a retrospective propensity score matching analysis (1:1) of patients treated with IMPT (years: 2016-2018) and VMAT (2014-2018). Survival was estimated using the Kaplan-Meier method. Multivariate Cox proportional hazards regression analysis was used to identify the independent predictors of survival. Binary toxicity endpoint analyses were performed using a Cox model and logistic regression. (3) Results: Eighty patients who received IMPT and VMAT were included. The median follow-up time was 24.1 months in the IMPT group. Progression-free survival (PFS) and overall survival (OS) were not statistically different between the two groups but potentially better in IMPT group. In multivariate analysis, advanced N-stage and body weight loss (BWL; >7%) during radiotherapy were associated with decreased PFS. The IMPT group had significantly less requirement for nasogastric (NG) tube placement and BWL during treatment. The mean oral cavity dose was the only predictive factor in stepwise regression analysis, and IMPT required a significantly lower mean dose. However, IMPT increased the grade 3 radiation dermatitis. (4) Conclusions: IMPT is associated with reduced rates of NG tube insertion and BWL through reducing oral mean dose, potentially producing better oncologic outcomes.

Digestion-Specific Acupuncture Effect on Feeding Intolerance in Critically Ill Post-Operative Oral and Hypopharyngeal Cancer Patients: A Single-Blind Randomized Control Trial

Malnourishment is prevalent in patients suffering from head and neck cancer. The postoperative period is crucial in terms of nutritional support, especially after composite resection and reconstruction surgery. These patients present with a number of risk factors that aggravate feeding intolerance, including postoperative status, prolonged immobility, decreased head elevation, mechanical ventilation, and applied sedative agents. Routine management protocols for feeding intolerance include prokinetic drug use and post-pyloric tube insertion, which could be both limited and accompanied by detrimental adverse events. This single-blind clinical trial aimed to investigate the effects of acupuncture in postoperative feeding intolerance in critically ill oral and hypopharyngeal cancer patients. Twenty-eight patients were randomized into two groups: Intervention group and Control group. Interventions were administered daily over three consecutive postoperative days. The primary outcome revealed that the intervention group reached 70% and 80% of target energy expenditure (EE) significantly earlier than the control group (4.00 ± 1.22 versus 6.69 ± 3.50 days, p = 0.012), accompanied by higher total calorie intake within the first postoperative week (10263.62 ± 1086.11 kcals versus 8384.69 ± 2120.05 kcals, p = 0.004). Furthermore, the intervention group also needed less of the prokinetic drug (Metoclopramide, 20.77 ± 48.73 mg versus 68.46 ± 66.56 mg, p = 0.010). In conclusion, digestion-specific acupuncture facilitated reduced postoperative feeding intolerance in oral and hypopharyngeal cancer patients.

Reducing outpatient gastrostomy tube complications

OBJECTIVE

To monitor the effectiveness of a multidisciplinary education protocol for gastrostomy tube (GT) use and care for patients to reduce complications postplacement.

METHODS

Baseline assessment included a preintervention/intervention design through quantitative measures to determine reduction in the number of GT complications postprocedure following implementation of a patient education protocol for 16 patients in the study.

INTERVENTION

A multidisciplinary approach was used in protocol development for standardizing patient education. Verbal, written, and hands-on demonstration methods for GT care were used to provide multiple education pathways to increase patient knowledge. Over the progression of 8 months (July 2019 to March 2020), patients with a new GT were followed postprocedure (1-2 weeks prior to starting radiation treatments) and throughout their course of radiation treatments (typically 6-7 weeks).

RESULTS

All 16 patients (100%) in the intervention group were included in the final analysis. GT complications were reduced from 91% in the preintervention group (n = 11) to 37% in the intervention group (n = 16). The most significant reduction occurred in technique issues, which decreased from 36% (n = 4) to 0%.

CONCLUSIONS

Implementation of a multidisciplinary approach with multiple educational sessions prior to GT placement and use led to increased patient knowledge and reduced GT complications.

The effect of timing of enteral nutrition support on feeding outcomes and dysphagia in patients with head and neck cancer undergoing radiotherapy or chemoradiotherapy: A systematic review

BACKGROUND & AIMS

Patients with head and neck cancer (HNC) often require enteral nutrition (EN). This systematic review reports the effect of EN timing in patients with HNC undergoing curative-intent and definitive or adjuvant radiotherapy or chemoradiotherapy on tube feeding duration, tube-related complications and dysphagia.

METHODS

Randomised controlled trials (RCTs) published between January 2015-April 2020 were obtained from Medline, CINAHL and Embase. Study quality and certainty of evidence were assessed with Cochrane Risk-of-Bias and Grading of Recommendations Assessment, Development and Evaluation (GRADE).

RESULTS

Two RCTs (n = 265) in five manuscripts were included. The risk of bias was moderate in one RCT and low in the other RCT. Timing of EN (prophylactic vs. reactive) may have little or no effect on tube feeding duration or complications, however, the effect on dysphagia was uncertain. Certainty of evidence was low for short-term and moderate for long-term tube feeding duration, low for tube-related complications and very low for dysphagia. There was imprecision due to small sample sizes, heterogeneity in the definitions and protocols for prophylactic and reactive EN, variations in time points for outcome assessment and indirect dysphagia measures.

CONCLUSION

Larger well-designed trials are warranted to increase certainty of evidence regarding EN timing in patients with HNC.

Prospective Evaluation of Sarcopenia in Head and Neck Cancer Patients Treated with Radiotherapy or Radiochemotherapy

Simple Summary

Radiation therapy (RT) is a key treatment for head and neck squamous cell carcinoma (HNSCC) patients. RT generates acute toxicity and weight loss, especially when combined with chemotherapy. Frail patients (malnourished or with poor performance status) have poor outcomes and increased toxicity when treated by RT. Among non-frail patients, predicting RT outcome is a challenge. Loss of muscle mass, also known as sarcopenia, is associated with poor outcome in HNSCC patients treated by RT and chemotherapy, but the level of evidence remains weak. Conflicting results exist regarding the impact of sarcopenia on acute RT toxicity. This prospective study confirmed that in non-frail HNSCC patients baseline sarcopenia is frequent (37%) and is associated with decreased overall and disease-free survival, but not with acute toxicity. Interestingly, a worse impact of sarcopenia occurred despite optimal nutritional support and even when patients were treated by RT without chemotherapy. Sarcopenia should be regarded as an independent prognostic factor in that setting.

Abstract

Highlights: Sarcopenia is frequent in patients treated with radiation therapy (RT) or radiochemotherapy (RTCT) for head and neck squamous cell carcinomas. Sarcopenia is associated with poor disease-free survival and overall survival outcomes. Sarcopenia is not associated with a higher rate of treatment-related toxicity. Background: Sarcopenia occurs frequently with the diagnosis of head and neck squamous cell carcinoma (HNSCC). We aimed to assess the impact of sarcopenia on survival among HNSCC patients treated with radiotherapy (RT) or radiochemotherapy (RTCT). Methods: Patients treated between 2014 and 2018 by RT or RTCT with curative intent were prospectively included (NCT02900963). Optimal nutritional support follow-up, including weekly consultation with a dietician and an oncologist and daily weight monitoring, was performed. Sarcopenia was determined by measuring the skeletal muscles at the L3 vertebra on the planning CT scan for radiotherapy. For each treatment group (RT or RTCT), we assessed the prognostic value of sarcopenia for disease-free survival (DFS) and overall survival (OS) and its impact on treatment-related toxicity. Results: Two hundred forty-three HNSCC patients were included: 116 were treated by RT and 127 were treated by RTCT. Before radiotherapy, eight (3.3%) patients were considered malnourished according to albumin, whereas 88 (36.7%) patients were sarcopenic. Overall, sarcopenia was associated with OS and DFS in a multivariate analysis (HR 1.9 [1.1–3.25] and 1.7 [1.06–2.71], respectively). It was similar for patients treated with RT (HR 2.49 [1.26–4.9] for DFS and 2.24 [1.03–4.86] for OS), whereas for patients treated with RTCT sarcopenia was significantly associated with OS and DFS in univariate analysis only. Sarcopenia was not related to higher treatment-related toxicity. Conclusions: Pretherapeutic sarcopenia remains frequent and predicts OS and DFS for non-frail patients treated with curative intent and adequate nutritional support.

Cancer Cachexia Affects Patients with Head and Neck Cancer in All Stages of Disease: A Prospective Cross-Sectional Study

The aim of the study was to determine the prevalence of cancer cachexia according to the clinical stage and determine differences in body composition, usual energy intake, and pro-inflammatory profile between cachectic and non-cachectic patients newly diagnosed with head and neck squamous cell carcinoma (HNSCC). A cross-sectional study was conducted in adult patients diagnosed with HNSCC admitted to the oncology unit before starting cancer treatment. Cancer cachexia was assessed according to Fearon criteria, and patients were divided into two groups: cachectic and non-cachectic patients. Body composition measured by bioelectrical impedance, energy intake, and biochemical and inflammatory markers were assessed. Comparative analyses were performed Student's-T test, using one-way ANOVA, chi-square and Mann Whitney-U test. Of the 79 consecutive patients included in the analysis, 72% (n = 57; 61 ± 15 years) were classified as cachectic and 28% (n = 22;59 ± 10 years) as non-cachectic. According to clinical stage, the prevalence of cachexia was stage I = 8.8%, stage II = 15.8%, stage III = 33.3% and stage IV = 42.1% (P = 0.564) and phase angle showed to be different between these groups (P < 0.05). Body composition showed that fat-free mass and total body water were significantly lower in patients with cachexia (p < 0.05). No differences were observed in phase angle, food intake or inflammatory markers between cachectic and non-cachectic patients. Cancer-cachexia is prevalent in all clinical stages in newly diagnosed patients with HNSCC. Early identification of cancer cachexia will allow initiate specialized nutrition support in a timely manner.

Enteral tube feeding of head and neck cancer patients undergoing definitive chemoradiotherapy in the Nordic Countries: Survey of the Scandinavian Society for Head and Neck Oncology

PURPOSE

We assessed current policies and perceptions of enteral tube feeding in head and neck cancer (HNC) patients undergoing chemoradiotherapy (CRT). A web-based survey was used to compare the timing and method of tube feeding within and between the five Nordic countries, covering a population of 27 million.

METHODS

From each of the 21 Nordic university hospitals, one oncologist and one otorhinolaryngology-head and neck (ORL-HN) surgeon responded to a survey. The respondents were asked whether tube insertion before the onset of CRT, or during CRT as required (prophylactic vs. reactive) was preferred. The use of a pretreatment nutritional screening tool and the choice of feeding route (nasogastric vs. gastrostomy tube) were assessed. In total, we analyzed responses from 21 oncologists and 21 ORL-HN surgeons.

RESULTS

A tendency was observed towards decreasing the use of a PEG tube. Of the 21 university hospitals, only 2 (10%) reported using a prophylactic PEG tube in over half of HNC patients undergoing definitive CRT. The preferred method for reactive tube feeding was by a NG tube in 14 of 21 (67%), and by a PEG in 7 of 21 (33%). In general, both oncologists and ORL-HN surgeons were content with their current policy.

CONCLUSIONS

The practices for enteral tube feeding in HNC management vary within and between the Nordic countries. We suggest that unified protocols for tube feeding should be developed for this patient population.

Nutritional Support in Head and Neck Radiotherapy Patients Considering HPV Status

Malnutrition is a common problem in patients with head and neck cancer (HNC), including oropharyngeal cancer (OPC). It is caused by insufficient food intake due to dysphagia, odynophagia, and a lack of appetite caused by the tumor. It is also secondary to the oncological treatment of the basic disease, such as radiotherapy (RT) and chemoradiotherapy (CRT), as a consequence of mucositis with the dry mouth, loss of taste, and dysphagia. The severe dysphagia leads to a definitive total impossibility of eating through the mouth in 20–30% of patients. These patients usually require enteral nutritional support. Feeding tubes are a commonly used nutritional intervention during radiotherapy, most frequently percutaneous gastrostomy tube. Recently, a novel HPV-related type of OPC has been described. Patients with HPV-associated OPC are different from the HPV− ones. Typical HPV− OPC is associated with smoking and alcohol abuse. Patients with HPV+ OPC are younger and healthy (without comorbidities) at diagnosis compared to HPV− ones. Patients with OPC are at high nutritional risk, and therefore, they require nutritional support in order to improve the treatment results and quality of life. Some authors noted the high incidence of critical weight loss (CWL) in patients with HPV-related OPC. Other authors have observed the increased acute toxicities during oncological treatment in HPV+ OPC patients compared to HPV− ones. The aim of this paper is to review and discuss the indications for nutritional support and the kinds of nutrition, including immunonutrition (IN), in HNC, particularly OPC patients, undergoing RT/CRT, considering HPV status.

European white paper: oropharyngeal dysphagia in head and neck cancer

Purpose

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

Methods

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

Results

Twenty-four sections on HNC-specific OD topics.

Conclusion

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

A prospective randomized controlled trial on the value of prophylactic oral nutritional supplementation in locally advanced nasopharyngeal carcinoma patients receiving chemo-radiotherapy

OBJECTIVES

We investigated the effect of prophylactic oral nutrition supplements (ONS) in locally advanced nasopharyngeal carcinoma patients receiving neoadjuvant chemotherapy and concurrent chemoradiotherapy (CCRT).

METHODS

Eligible patients were randomly assigned to an intervention or control group. Patients in the intervention group were supported with prophylactic ONS from the beginning of CCRT. The control group received nutritional support only when necessary. Bodyweight, hematological indexes, nutritional status, and quality of life were measured at baseline and before, during, and after RT.

RESULTS

We evaluated 114 patients from October 2016 to May 2018. More than half of patients experienced significant weight loss during CCRT, which continued for three months after radiotherapy (RT). Compared to baseline, the rate of weight loss ≥ 5% before, during, at the end of RT, and one and three months after RT were 3.5%, 28.9%, 51.8%, 61.4%, and 61.4%, respectively. Nutritional status and global health status scores progressively decreased during treatment. The rate of RT interruption was higher in the control group than in the intervention group (7.14% vs. 0%, χ² = 4.29, P = 0.04). More patients experienced concurrent chemotherapy interruption in the control group than in the intervention group (28.57% vs 10.34%, χ² = 6.08, P = 0.01). There were no significant differences in weight loss, nutritional status, quality of life, and global health status between two groups.

CONCLUSIONS

Malnutrition and weight loss progressively increased during treatment. Prophylactic ONS can improve tolerance to CCRT, but it offers no advantage on short-term weight loss or nutritional assessment scores.

Disease-induced and treatment-induced alterations in body composition in locally advanced head and neck squamous cell carcinoma

BACKGROUND

Chemoradiation or bioradiation treatment (CRT/BRT) of locally advanced head and neck squamous cell carcinoma (LAHNSCC) comes with high toxicity rates, often leading to temporary tube feeding (TF) dependency. Cachexia is a common problem in LAHNSCC. Yet changes in body composition and muscle weakness during CRT/BRT are underexplored. Strong evidence on the effect of TF on body composition during treatment is lacking. The aim of this cohort study was to assess (i) the relationship of fat-free mass index (FFMI) and handgrip strength (HGS) with CRT/BRT toxicity and outcome, (ii) body composition in patients treated with chemoradiation (cisplatin) vs. bioradiation (cetuximab), and (iii) the effect of the current TF regime on body composition and muscle strength.

METHODS

Locally advanced head and neck squamous cell carcinoma patients treated with CRT/BRT between January 2013 and December 2016 were included (n = 137). Baseline measurements of body composition (bioelectrical impedance analysis) and HGS were performed. Toxicity grades (Common Terminology Criteria for Adverse Events) were scored. In a subset of 69 patients, weight loss, body composition, and HGS were additionally assessed during and after CRT/BRT. TF was initiated according to the Dutch guidelines for malnutrition.

RESULTS

In this cohort (68% male, mean age 59 ± 8 years), the incidence of baseline muscle wasting, defined as FFMI < P₁₀ , was 29%. Muscle wasting was present in 23 of 100 (23%) chemoradiation patients and 17 of 37 (46%) bioradiation patients (P = 0.009). Muscle-wasted patients required more unplanned hospitalizations during CRT (P = 0.035). In the chemoradiation subset, dose-limiting toxicity was significantly higher in wasted vs. non-wasted patients (57% vs. 25%, P = 0.004). Median follow-up was 32 months. Multivariate Cox regression analysis identified muscle wasting as independent unfavourable prognostic factor for overall survival [hazard ratio 2.1 (95% CI 1.1-4.1), P = 0.022] and cisplatin as favourable prognostic factor [hazard ratio 0.3 (95% CI 0.2-0.6), P = 0.001]. Weight and HGS significantly decreased during CRT/BRT, -3.7 ± 3.5 kg (P < 0.001) and -3.1 ± 6.0 kg (P < 0.001), respectively. Sixty-four per cent of the patients required TF 21 days (range 0-59) after CRT/BRT initiation. Total weight loss during CRT/BRT was significantly (P = 0.007) higher in the total oral diet group (5.5 ± 3.7 kg) compared with the TF group (3.0 ± 3.2 kg). Loss of FFM and HGS was similar in both groups.

CONCLUSIONS

In LAHNSCC patients undergoing CRT/BRT, FFMI < P₁₀ is an unfavourable prognostic factor for overall survival, treatment toxicity, and tolerance. Patients experience significant weight and FFM loss during treatment. Current TF regime attenuates weight loss but does not overcome loss of muscle mass and function during therapy. Future interventions should consider nutritional intake and additional strategies specifically targeting metabolism, loss of muscle mass, and function.

Compliance and Adherence to Enteral Nutrition Treatment in Adults: A Systematic Review

OBJECTIVE

To review the scientific literature that has verified and/or assessed compliance and adherence to enteral nutrition (EN) in adult patients.

METHOD

This study involved a critical analysis of articles retrieved from MEDLINE (PubMed), The Cochrane Library, Embase, Scopus and Web of Science using the terms "Treatment Adherence and Compliance" and "Enteral Nutrition", applying the filters "Comparative Study" or "Clinical Trial", "Humans" and "Adults". Date of the search: 25 October 2018.

RESULTS

A total of 512 references were retrieved, of which 23 documents were selected after applying the inclusion and exclusion criteria. The techniques measuring adherence to EN were determined by dietary intake, self-reporting, counts of leftover containers or presence of complications; however, in no case were validated questionnaires used. The time and periodicity of the assessment presented very heterogeneous results, with measurement predominantly being done at the beginning and at the end of the study. The best adherence rates were obtained in hospitalized patients (approximately 80%).

CONCLUSIONS

Frequent and regular monitoring of the adherence of patients under prolonged treatment with EN is necessary, and the use of measurement techniques that allow obtaining information on the causes of non-adherence facilitates early interventions to optimize treatment outcomes. Patient and/or caregiver education in the management of EN and the intervention of the community pharmacy in monitoring patients can be key to improving the adherence to EN.

Nutritional support dependence after curative chemoradiotherapy in head and neck cancer: supplementary analysis of a phase II trial (JCOG0706S1)

Objectives

To explore the risk factors of laryngo-esophageal dysfunction-free survival and nutritional support dependence over 12 months in patients with unresectable locally advanced head and neck carcinomas who received chemoradiotherapy in a phase II trial of JCOG0706 (UMIN000001272).

Methods

Forty-five patients received radiation therapy for a total of 70 Gy/35fr concurrently with S-1 and cisplatin. Risk factors of laryngo-esophageal dysfunction-free survival and nutritional support dependence over 12 months were analyzed using Cox regression models and logistic regression models, respectively, with consideration to patient laboratory data just before chemoradiotherapy. Radiation fields were reviewed to analyze the relationship between the extent of the irradiated field and functional outcome.

Results

With a median follow-up period of 3.5 years, 3-year laryngo-esophageal dysfunction-free survival was 48.9%. For laryngo-esophageal dysfunction-free survival, hazards ratio of 2.35 in patients with nutritional support at registration (vs. without nutritional support; 95% confidence interval 0.96–5.76). For nutritional support dependence over 12 months, odds ratio was 6.77 in patients with hemoglobin less than the median of 13.4 g/dl (vs. higher than or equal to the median; 95% confidence interval 1.24–36.85) and was 6.00 in patients with albumin less than the median of 3.9 g/dl (vs. higher than or equal to the median; 95% confidence interval 1.11–32.54). Primary sites in disease-free patients with nutritional support dependence over 12 months were the oropharynx (N = 2) or hypopharynx (N = 1), and all pharyngeal constrictor muscles were included in irradiated fields with a curative dose.

Conclusions

This supplementary analysis showed that pretreatment severe dysphagia requiring nutritional support, anemia and hypoalbuminemia might have a negative prognostic impact on long-term functional outcomes after curative chemoradiotherapy in head and neck cancer.

Selection of systemic therapy in patients with locally advanced and recurrent/metastatic head and neck cancer: RAND-based expert opinion by an Italian multidisciplinary panel

BACKGROUND

Head and neck squamous cell carcinoma (HNSCC) is a heterogeneous disease often presenting at an already advanced stage. Cisplatin chemoradiotherapy is the standard treatment for locally advanced disease, although its efficacy varies according to different studies. Thus, treatment selection is a challenge, especially in older patients, who frequently have several comorbidities. Moreover, the majority of patients with recurrent and/or metastatic disease are unsuitable for local treatment, either surgery or radiation therapy. The only treatment option for them is systemic therapy, but prognosis remains poor, with a median overall survival of less than 12 months.

METHODS

A group of Italian key opinion leaders in the field of HNSCC gathered several times in 2018 in order to retrieve a set of statements to help clinicians in their daily decision-making process for the treatment of patients with different scenarios of HNSCC.

RESULTS AND CONCLUSION

The panel agreed on 22 statements that were identified as "good clinical points" based on the available literature or after discussion of the most relevant aspect of the underlying diseases when no international consensus was available. The panel identified a number of possible scenarios (namely 71) in which these statements may be helpful to guide decision-making for the best treatment selection.

Enteral Nutrition in Pediatric High-risk Head and Neck Cancer Patients Receiving Proton Therapy: Identifying Risk Factors and Quality of Life Concerns to Optimize Care

BACKGROUND

Radiotherapy for pediatric head and neck tumors often results in mucositis and pain, limiting oral intake and compromising patients' nutrition. There are little pediatric data available regarding enteral tube use and risk factors. Our objective was to estimate nutrition needs, identify risk factors contributing to nutritional decline and explore quality of life measures regarding enteral nutrition during proton radiotherapy.

PROCEDURE

Nutritional metrics and status were collected throughout radiation treatment for 32 patients. We surveyed patients/caregivers about their perceptions of enteral nutrition. Risk factors for progression to non-oral nutrition or >5% weight loss were evaluated using univariate analysis.

RESULTS

Patients who received any esophageal radiation or >30 Gy mean dose to the pharyngeal constrictors were more likely to experience >5% weight loss. These patients, as well as those who received a mean dose >30 Gy to the oropharynx or concurrent chemotherapy, were also more likely to require non-oral supplementation. Patients expressed the importance of maximizing nutrition and feared pain associated with a tube placement.

CONCLUSIONS

Pediatric patients with head and neck cancer can be risk-stratified based on clinical and dosimetric factors. This data, combined with parent and patient perceptions, is key to the development of rational guidelines.

Risk of Unplanned Hospital Encounters in Patients Treated With Radiotherapy for Head and Neck Squamous Cell Carcinoma

CONTEXT

Radiotherapy is highly effective for treating squamous cell carcinoma of the head and neck but is often associated with significant toxicities and severe morbidity. Unplanned emergency department (ED) visits and hospitalizations are common during treatment and come with a substantial financial and health burden as well as the potential for impaired long-term outcomes due to treatment disruption.

OBJECTIVES

The objective of this study was to identify patient, disease, and treatment characteristics that were associated with ED encounters and admissions.

METHODS

A cohort of 462 patients with cancer of the head and neck treated with radiotherapy at UT Southwestern between 2010 and 2015 was retrospectively analyzed. The risks of ED visits, admissions, multiple admissions, and extended admissions were determined. Risk factors for an unplanned hospital encounter were analyzed using univariate and multivariate logistic regression.

RESULTS

Overall, 36% of patients had an unplanned hospital encounter during the treatment window. Patients with advanced disease, those with high comorbidity score, and those treated with concurrent chemotherapy were more likely to have unplanned admissions/ED visits. Social factors such as marital status, smoking status, and registration in the public hospital system were also strongly associated with admissions and multiple encounters.

CONCLUSION

The high rate of admissions and ED visits emphasizes the importance of anticipating and managing toxicities during treatment. Social factors have a strong association with unplanned encounters and may present opportunities for targeted interventions to reduce admissions for patients at highest risk.

Malnutrition in head and neck cancer patients: Impacts and indications of a prophylactic percutaneous endoscopic gastrostomy

INTRODUCTION

Head and neck cancer (HNC) patients often experience malnutrition before and during treatment. Prophylactic gastrostomy has emerged as an efficient tool for ensuring adequate nutrition. However, there is no suitable algorithm able to identify patients at high risk of malnutrition. The aim of this study was to describe the nutritional management, to assess the impact of prophylactic gastrostomy, and to identify predictors of malnutrition.

METHODS

This retrospective study included 152 patients treated with surgery, radiotherapy, or chemotherapy for HNC. The patients were classified according to their gastrostomy status (prophylactic or non-prophylactic). Nutritional, tumoral and treatment characteristics were reported. Clinical and nutritional outcomes were measured 6 weeks after the beginning of treatment. In order to describe the nutritional management and the impact of prophylactic gastrostomy on patients, univariate analysis was generated using chi-square test and Mann-Whitney test or Student's t-test. Logistic regression was performed to identify factors associated with malnutrition.

RESULTS

Forty-one patients received prophylactic gastrostomy whereas 111 patients had no nutritional support. Prophylactic gastrostomy placement was associated with a lower initial body mass index, with severe malnutrition, and with initial oral intake disorder. Patients who did not experienced prophylactic gastrostomy had much worse outcomes such as hospital readmissions (P=0.042), relative weight loss at 6 weeks (P<0.0001), dysphagia, severe malnutrition, and poor state of health (P=0.001). Our complication rates (4.9%) were lower than the usual range (5.9-9.3%) and no life-threatening complication was reported. Positive N status, oral intake disorder, concomitant radiochemotherapy, nasopharyngeal, and hypopharyngeal tumor site were significant predictive factors for malnutrition.

CONCLUSIONS

Prophylactic percutaneous endoscopic gastrostomy showed advantages in terms of hospital readmissions, relative weight loss at 6 weeks, dysphagia, severe malnutrition, and poor state of health. Tumoral, nutritional and treatment characteristics seem to be predictors for malnutrition. Hence, physicians should integrate these factors in their nutrition algorithm approach.

Preoperative low skeletal muscle mass as a risk factor for pharyngocutaneous fistula and decreased overall survival in patients undergoing total laryngectomy

Background

Low skeletal muscle mass (SMM) is associated with postoperative complications, prolonged hospital stay, and short overall survival (OS) in surgical oncology. We aimed to investigate this association in patients undergoing total laryngectomy (TL).

Methods

A retrospective study was performed of patients undergoing TL. SMM was measured using CT or MRI scans at the level of the third cervical vertebra (C3).

Results

In all, 235 patients were included. Low SMM was observed in 109 patients (46.4%). Patients with low SMM had more pharyngocutaneous fistulas (PCFs) than patients with normal SMM (34.9% vs 20.6%; P = .02) and prolonged hospital stay (median, 17 vs 14 days; P < .001). In multivariate analysis, low SMM (hazards ratio, 1.849; 95% confidence interval, 1.202‐2.843) and high N stage were significant prognosticators of decreased OS.

Conclusion

Low SMM is associated with PCF and prolonged hospital stay in patients undergoing TL. Low SMM is an independent prognostic factor for shorter OS.

Benefits of Oral Nutritional Supplements in Patients with Locally Advanced Nasopharyngeal Cancer during Concurrent Chemoradiotherapy: An Exploratory Prospective Randomized Trial

BACKGROUND

Weight loss during chemoradiotherapy is a major problem in patients with head and neck cancer. The aim of this study was to evaluate the effect of ONS on weight, nutritional status and quality of life (QOL) in patients with loco-regionally advanced nasopharyngeal cancer (NPC) undergoing chemoradiotherapy.

METHODS

Patients with locally advanced NPC treated at a tertiary hospital in China prior to curative chemoradiotherapy were eligible for this exploratory randomized study. Patients were assigned to either the intervention or the control group based on a computer-generated randomization sequence. The intervention group commenced ONS at the start of chemoradiotherapy. Outcomes included body weight, BMI, nutritional status and QOL.

RESULTS

From June 2015 to June 2016, 50 patients with NPC were randomized to intervention and 50 to the control group. Patients in the ONS group had a higher body weight at the end of chemoradiotherapy (59.11 kg vs 58.14 kg, p = 0.036). A higher BMI and prealbumin were observed in the ONS group (p = 0.021 and p = 0.048, respectively). No other differences were found for nutritional status, QOL or clinical outcomes.

CONCLUSION

ONS had beneficial outcomes in terms of reducing weight loss, minimizing BMI decrease and increasing protein intake in loco-regionally advanced NPC patients during chemoradiotherapy.

The impact of HPV status on weight loss and feeding tube use in oropharyngeal carcinoma

OBJECTIVES

It has been well established that patients with oropharyngeal carcinoma are at high nutritional risk, with significant weight loss and tube feeding common. Human papillomavirus (HPV)-associated disease has led to a change in the "typical" presentation and nutritional profile of this population. The aim of our study was to determine whether the need for a feeding tube, and weight loss during radiotherapy (RT) in patients with oropharyngeal carcinoma differed with HPV status.

MATERIALS AND METHODS

Patients who received curative RT ± chemotherapy from January 2011 to January 2016 were included (n = 100). We retrospectively evaluated feeding tube use and timing of insertion (prophylactic vs reactive), percentage weight loss during RT and the prevalence of critical weight loss (CWL) ≥5%.

RESULTS

HPV-positive patients had significantly higher weight loss during RT compared to the rest of the cohort (8.4% vs 6.1%, 95%CI 0.8-3.9, p = 0.003). CWL was observed in 86% and in a higher proportion with HPV-positive disease (93%, p = 0.011). Conditional probability modelling analysis revealed, with 74% accuracy, concurrent chemoradiotherapy and HPV-positive status were predictors of CWL when comparing HPV-positive patients to HPV-negative (96%, p = 0.001 and 98%, p = 0.012 respectively). More HPV-positive patients required feeding tubes (n = 43, 63%, p = 0.05), most being reactive (n = 27, 63%). All patients with reactive tubes experienced CWL.

CONCLUSION

The high incidence of CWL in patients with HPV-positive oropharyngeal carcinoma is of concern. Tube feeding continues to be a necessary nutritional intervention in this population and predicting who will require a tube is challenging. Larger, prospective cohort studies are required.

Nutritional counseling with or without systematic use of oral nutritional supplements in head and neck cancer patients undergoing radiotherapy

BACKGROUND

To evaluate the benefit of oral nutritional supplements (ONS) in addition to nutritional counseling in head and neck cancer (HNC) patients undergoing radiotherapy (RT).

METHODS

In a single-center, randomized, pragmatic, parallel-group controlled trial (ClinicalTrials.gov: NCT02055833; February 2014-August 2016), 159 newly diagnosed HNC patients suitable for to RT regardless of previous surgery and induction chemotherapy were randomly assigned to nutritional counseling in combination with ONS (N = 78) or without ONS (N = 81) from the start of RT and continuing for up to 3 months after its end. Primary endpoint was the change in body weight at the end of RT. Secondary endpoints included changes in protein-calorie intake, muscle strength, phase angle and quality of life and anti-cancer treatment tolerance.

RESULTS

In patients with the primary endpoint assessed (modified intention-to-treat population), counseling plus ONS (N = 67) resulted in smaller loss of body weight than nutritional counseling alone (N = 69; mean difference, 1.6 kg [95%CI, 0.5-2.7]; P = 0.006). Imputation of missing outcomes provided consistent findings. In the ONS-supplemented group, higher protein-calorie intake and improvement in quality of life over time were also observed (P < 0.001 for all). The use of ONS reduced the need for changes in scheduled anti-cancer treatments (i.e. for RT and/or systemic treatment dose reduction or complete suspension, HR=0.40 [95%CI, 0.18-0.91], P = 0.029).

CONCLUSION

In HNC patients undergoing RT or RT plus systemic treatment, and receiving nutritional counseling, the use of ONS resulted in better weight maintenance, increased protein-calorie intake, improved quality of life and was associated with better anti-cancer treatment tolerance.
