Nutritional challenges in head and neck cancer

The Relationship between miR-5682 and Nutritional Status of Radiotherapy-Treated Male Laryngeal Cancer Patients

BACKGROUND

Nutritional deficiencies are frequently observed in patients with head and neck cancer (HNC) undergoing radiation therapy. microRNAs (miRNAs) were found to play an important role in the development of metabolic disorders throughout regulation of genes involved in inflammatory responses. This study aimed to explore the correlation between pre-treatment miR-5682 expression and parameters reflecting nutritional deficits in laryngeal cancer (LC) patients subjected to radiotherapy (RT).

METHODS

Expression of miR-5682 was analyzed in plasma samples of 56 male LC individuals. Nutritional status of LC patients was assessed using anthropometric and laboratory parameters, bioelectrical impedance analysis (BIA) and clinical questionnaires.

RESULTS

A high expression of miR-5682 was associated with significantly lower values of BMI, fat mass, fat-free mass and plasma albumin at selected periods of RT course. miR-5682 allowed us to distinguish between patients classified with both SGA-C and low albumin level from other LC patients with 100% sensitivity and 69.6% specificity (AUC = 0.820; p < 0.0001). Higher expression of studied miRNA was significantly associated with shorter median overall survival (OS) in LC patients (HR = 2.26; p = 0.008).

CONCLUSIONS

analysis of miR-5682 expression demonstrates a potential clinical utility in selection of LC patients suffering from nutritional deficiencies developing as a consequence of RT-based therapy.

Needs assessment for a decision support tool in oral cancer requiring major resection and reconstruction: a mixed-methods study protocol

INTRODUCTION

Advanced oral cancer and its ensuing treatment engenders significant morbidity and mortality. Patients are often elderly with significant comorbidities. Toxicities associated with surgical resection can be devastating and they are often highlighted by patients as impactful. Given the potential for suboptimal oncological and functional outcomes in this vulnerable patient population, promotion and performance of shared decision making (SDM) is crucial.Decision aids (DAs) are useful instruments for facilitating the SDM process by presenting patients with up-to-date evidence regarding risks, benefits and the possible postoperative course. Importantly, DAs also help elicit and clarify patient values and preferences. The use of DAs in cancer treatment has been shown to reduce decisional conflict and increase SDM. No DAs for oral cavity cancer have yet been developed.This study endeavours to answer the question: Is there a patient or surgeon driven need for development and implementation of a DA for adult patients considering major surgery for oral cancer?

METHODS AND ANALYSIS

This study is the first step in a multiphase investigation of SDM during major head and neck surgery. It is a multi-institutional convergent parallel mixed-methods needs assessment study. Patients and surgeon dyads will be recruited to complete questionnaires related to their perception of the SDM process (nine-item Shared Decision-Making Questionnaire, SDM-Q-9 and SDM-Q-Doc) and to take part in semistructured interviews. Patients will also complete questionnaires examining decisional self-efficacy (Ottawa Decision Self-Efficacy Scale) and decisional conflict (Decisional Conflict Scale). Questionnaires will be completed at time of recruitment and will be used to assess the current level of SDM, self-efficacy and conflict in this setting. Thematic analysis will be used to analyse transcripts of interviews. Quantitative and qualitative components of the study will be integrated through triangulation, with matrix developed to promote visualisation of the data.

ETHICS AND DISSEMINATION

This study has been approved by the research ethics boards of the Nova Scotia Health Authority (Halifax, Nova Scotia) and the University Health Network (Toronto, Ontario). Dissemination to clinicians will be through traditional approaches and creation of a head and neck cancer SDM website. Dissemination to patients will include a section within the website, patient advocacy groups and postings within clinical environments.

The anatomy and physiology of normal and abnormal swallowing in oropharyngeal dysphagia

BACKGROUND

Eating and drinking are enjoyable activities that positively impact on an individual's quality of life. The ability to swallow food and fluid is integral to the process of eating. Swallowing occupies a dual role being both part of the enjoyment of eating and being a critically important utilitarian activity to enable adequate nutrition and hydration. Any impairment to the process of swallowing can negatively affect a person's perception of their quality of life. The process of swallowing is highly complex and involves muscles in the mouth, pharynx, larynx, and esophagus. The oropharynx is the anatomical region encompassing the oral cavity and the pharynx. Food must be masticated, formed into a bolus and transported to the pharynx by the tongue whereas fluids are usually held within the mouth before being transported ab-orally. The bolus must then be transported through the pharynx to the esophagus without any matter entering the larynx. The muscles needed for all these steps are coordinated by swallowing centers within the brainstem which are supplied with sensory information by afferent nerve fibers from several cranial nerves. The swallowing centers also receive modulatory input from higher centers within the brain. Hence, a swallow has both voluntary and involuntary physiologic components and the term dysphagia is given to difficult swallowing while oropharyngeal dysphagia is difficult swallowing due to pathology within the oropharynx.

PURPOSE

Problems affecting any point along the complex swallowing pathway can result in dysphagia. This review focuses on the anatomy and physiology behind normal and abnormal oropharyngeal swallowing. It also details the common diseases and pathology causing oropharyngeal dysphagia.

Evidence-Based Support for Nutrition Therapy in Head and Neck Cancer

PURPOSE OF REVIEW

Patients diagnosed with head and neck (H&N) cancer often present in a malnourished state for varied reasons; nutritional optimization is therefore critical to the success of treatment for these complex patients. This article aims to review the current nutrition literature pertaining to H&N cancer patients and to present evidence-based strategies for nutritional support specific to this population.

RECENT FINDINGS

Aggressive nutritional intervention is frequently required in the H&N cancer patient population. Rehabilitating nutrition during operative and nonoperative treatment improves compliance with treatment, quality of life, and clinical outcomes. When and whether to establishing alternative enteral access are points of controversy, although recent evidence suggests prophylactic enteral feeding tube placement should not be universally applied. Perioperative nutritional optimization including preoperative carbohydrate loading and provision of arginine-supplemented immunonutrition has been shown to benefit at-risk H&N cancer patients.

SUMMARY

With multidisciplinary collaboration, H&N cancer patients can receive individualized nutritional support to withstand difficult cancer treatment regimens and return to acceptable states of nutritional health.

Efficacy of electrical stimulation and exercise for dysphagia in patients with head and neck cancer: A randomized clinical trial

BACKGROUND

Neuromuscular electrical stimulation (NMES) is a highly sought after but poorly studied treatment for dysphagia among patients with head and neck cancer with dysphagia. This study investigated the efficacy of NMES in this patient population.

METHODS

In this double-blinded, randomized controlled trial, 170 patients with head and neck cancer experiencing posttreatment dysphagia were randomized into active NMES + swallow exercise versus sham NMES + swallow exercise groups. Outcomes after a 12-week program included changes in fluoroscopy measures, diet, and quality of life.

RESULTS

After the 12-week program, the active NMES group had significantly worse Penetration Aspiration Scale scores than the sham group. Both groups reported significantly better diet and quality of life. No other measures were significant.

CONCLUSION

NMES did not add benefit to traditional swallow exercises. Unfortunately, swallow exercises were not effective by themselves either. For patients with head and neck cancer with moderate to severe dysphagia caused by radiation therapy, current behavioral therapies are of limited help in reversing long-term dysphagia. © 2015 Wiley Periodicals, Head Neck 38: E1221-E1231, 2016.

Dysphagia in the elderly

Dysphagia, or difficulty swallowing, is a common problem in the elderly. Based on the initial clinical history and physical examination, the dysphagia is assessed as either primarily oropharyngeal or esophageal in origin. Most oropharyngeal dysphagia is of neurologic origin, and management is coordinated with a clinical swallow specialist in conjunction with an ear, nose, and throat (ENT) physician if warning signs imply malignancy. Several structural and functional esophageal disorders can cause dysphagia. If a patient has likely esophageal dysphagia, a video barium esophagram is a good initial test, and referral to a gastroenterologist is generally warranted leading to appropriate treatment.

Quality of life and supportive care for patients with metastatic renal cell carcinoma

In recent years, a key issue in the management of patients with metastatic renal cell carcinoma (mRCC) has been the assessment of health-related quality of life (HRQoL), particularly following the introduction of targeted therapies that have brought significant improvements in progression-free survival and quality of life in these patients. HRQoL is becoming one of the main factors influencing choice of therapy, and HRQoL experienced during first-line treatment may affect the choice of the second-line therapy. Consequently, several trials have been conducted to evaluate the impact of approved targeted therapies for mRCC on HRQoL, and this measure is being introduced with increasing frequency in the trial design. With respect to agents used after progression on cytokines, sunitinib and temsirolimus have yielded better HRQoL scores, and sorafenib and pazopanib have shown stable HRQoL scores compared with placebo. Regarding targeted agents approved for patients who progress on a first-line tyrosine kinase inhibitor, everolimus has shown to delay and reduce the degree of Karnofsky performance status deterioration compared with placebo. Moreover, evidence obtained from these trials shows that tumor response and delay in disease progression affect HRQoL. In this article, we review the different HRQoL scales used to evaluate patients with mRCC along with the results obtained in clinical trials. Given that HRQoL is determined not only by treatment-related effects but also by mRCC symptoms and its clinical complications, the characteristics and appropriate treatment of the most commonly experienced symptoms, including anorexia, fatigue, pain, anemia, and venous thromboembolism, are also reviewed.

Nutrition support for head and neck squamous cell carcinoma patients treated with chemoradiotherapy: how often and how long?

Background. Oral intake of many patients with locally advanced head and neck cancer (LAHNC) decrease during chemoradiotherapy (CRT). Although prophylactic percutaneous endoscopic gastrostomy (PEG) is recommended, not a few patients complete CRT without using PEG tube. Patients and Methods. The subjects were patients with LAHNC who received CRT. We retrospectively investigated the incidence and duration of nutritional support during and after CRT, and predicting factors of nutritional support. For patients who required nutritional support, we also checked the day of initiation and the duration of nutritional support. Results. Of 53 patients, 29 patients (55%) required nutritional support during and/or after CRT. While no clear relation between requirement of nutritional support and variables including age, T stage, N stage, clinical stage and chemotherapy regimen, there could be some relationships between tumor primary sites and the requirement and duration of nutritional support. 17 (77%) of 22 patients with oropharynx cancer(OP) required nutritional support and prolonged for 4.4 months, and 11 (46%) of 24 patients with hypopharynx cancer(HP) required nutritional support and prolonged for 21.9 months. Conclusion. Nutritional support is indicated many HNC patients treated with CRT and primary sites may have some relation to its indication and duration.

Weight changes in oncology patients during the first year after diagnosis: a qualitative investigation of the patients' experiences

BACKGROUND

Weight changes are one of the most common symptoms experienced by patients with cancer. However, limited empirical data are available on how cancer patients react to changes in their weight following their diagnosis and treatment.

OBJECTIVE

The present study aims to acquire a deeper understanding of cancer patients' experiences with the physical manifestations of weight loss or gain, the consequence of these changes on their psychosocial life, and their self-management strategies.

METHODS

Semistructured interviews with 54 cancer patients were conducted longitudinally 2 to 3 weeks after their diagnosis. Follow-up interviews were carried out at 3, 6, and 12 months after diagnosis.

RESULTS

From the 54 patients recruited, 34 patients disclosed weight gain, whereas 37 experienced weight loss, suggesting that 17 patients experienced weight fluctuation. Analysis generated 4 themes that reflected the complex dynamics of weight change. Themes were "experiences with the physical manifestations of weight loss or gain," "psychological effects," "self-management," and "social consequences."

CONCLUSION

This study confirms that weight changes have far more complicated implications for patients with cancer, extending beyond physical problems into psychosocial issues. Changes are a constant reminder of the diagnosis and treatment and are persistent across all stages.

IMPLICATIONS FOR PRACTICE

These findings highlight the importance of nutritional psychosocial rehabilitation programs during the cancer trajectory.

A prospective investigation of swallowing, nutrition, and patient-rated functional impact following altered fractionation radiotherapy with concomitant boost for oropharyngeal cancer

Altered fractionation radiotherapy for head and neck cancer has been associated with improved locoregional control, overall survival, and heightened toxicity compared with conventional treatment. Swallowing, nutrition, and patient-perceived function for altered fractionation radiotherapy with concomitant boost (AFRT-CB) for T1-T3 oropharyngeal squamous cell carcinoma (SCC) have not been previously reported. Fourteen consecutive patients treated with AFRT-CB for oropharyngeal SCC were recruited from November 2006 to August 2009 in a tertiary hospital in Brisbane, Australia. Swallowing, nutrition, and patient-perceived functional impact assessments were conducted pretreatment, at 4-6 weeks post-treatment, and at 6 months post-treatment. Deterioration from pretreatment to 4-6 weeks post-treatment in swallowing, nutrition, and functional impact was evident, likely due to the heightened toxicity associated with AFRT-CB. There was significant improvement at 6 months post-treatment in functional swallowing, nutritional status, patient-perceived swallowing, and overall function, consistent with recovery from acute toxicity. However, weight and patient perception of physical function and side effects remained significantly worse than pretreatment scores. The ongoing deficits related to weight and patient-perceived outcomes at 6 months revealed that this treatment has a long-term impact on function possibly related to the chronic effects of AFRT-CB.

Pretreatment organ function in patients with advanced head and neck cancer: clinical outcome measures and patients' views

BACKGROUND

Aim of this study is to thoroughly assess pretreatment organ function in advanced head and neck cancer through various clinical outcome measures and patients' views.

METHODS

A comprehensive, multidimensional assessment was used, that included quality of life, swallowing, mouth opening, and weight changes. Fifty-five patients with stage III-IV disease were entered in this study prior to organ preserving (chemoradiation) treatment.

RESULTS

All patients showed pretreatment abnormalities or problems, identified by one or more of the outcome measures. Most frequent problems concerned swallowing, pain, and weight loss. Interestingly, clinical outcome measures and patients' perception did no always concur. E.g. videofluoroscopy identified aspiration and laryngeal penetration in 18% of the patients, whereas only 7 patients (13%) perceived this as problematic; only 2 out of 7 patients with objective trismus actually perceived trismus.

CONCLUSION

The assessment identified several problems already pre-treatment, in this patient population. A thorough assessment of both clinical measures and patients' views appears to be necessary to gain insight in all (perceived) pre-existing functional and quality of life problems.

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

BACKGROUND & AIMS

To determine the prevalence of dysphagia in head and neck cancer patients treated with surgery and radiotherapy or chemoradiotherapy. To study the impact of dysphagia on food habits, nutritional status, and quality of life.

METHODS

Retrospective cross-sectional study of 87 head and neck cancer patients treated with surgery and radiotherapy or chemoradiotherapy from January 2000 through May 2005. Time since surgery was 28.5+/-17.8 months. A clinical test was used to detect dysphagia. A nutritional assessment was performed in all patients. A questionnaire was used to evaluate quality of life.

RESULTS

Oropharyngeal dysphagia was present in 50.6% of patients, mostly to solid foods (72.4%). Patients with total glossectomy and chemoradiotherapy had the highest rate of dysphagia. Nutritional support was necessary in 57.1% of patients. Malnutrition was present in 20.3% of patients, mainly marasmus (81%). Fifty-one percent of patients reported a decrease in their quality of life due to dysphagia.

CONCLUSIONS

We found a high prevalence of dysphagia in head and neck cancer patients treated with surgery and coadjuvant treatment. This problem negatively affects their quality of life. It is important that nutritional surveillance be provided to detect it and to prevent malnutrition.

Relation between nutritional state and postoperative complications in patients with oral and maxillofacial malignancy

PURPOSE

To evaluate the role of nutrition in the development of postoperative complications in patients with oral and maxillofacial malignancy.

PATIENTS AND METHODS

Ninety-six patients treated surgically for oral and maxillofacial malignancy, 27 of whom developed postoperative complications; the remaining 69 recovered uneventfully. Nutritional state and clinical variables in the two groups were compared.

RESULTS

The incidence of poor nutrition was greater in the complication group (56%) than in the uncomplicated group (20%) (p<0.001); the values for body weight, triceps skinfold thickness, arm circumference, arm muscle circumference, and creatinine-height index decreased more in the complicated than in the uncomplicated group (p<0.001); nitrogen and calorie intake during the first postoperative week was less in the complicated than in the uncomplicated group (p<0.001).

CONCLUSIONS

Poor nutrition plays an important part in the development of postoperative complications, and perioperative nutritional support of patients with oral and maxillofacial cancer must be properly managed.

Patients experience with long-term percutaneous endoscopic gastrostomy feeding following primary surgery for oral and oropharyngeal cancer

Percutaneous endoscopic gastrostomy feeding (PEG) has an important role in providing nutritional support in selected patients undergoing treatment for oral and oropharyngeal cancer. Although morbidity data have been published there is very little from the patient perspective. The aim of this project was to devise, pilot and survey a PEG specific questionnaire and relate outcomes to health-related quality of life. A cross-sectional survey was conducted in April 2005 of patients who were alive and disease free and treated by primary surgery for oral and oropharyngeal squamous cell carcinoma between 1992 and June 2004. The survey comprised the University of Washington Quality of Life questionnaire and a 24 item PEG questionnaire. Of 344 alive and disease free patients, 243 (71%) responded. Clinical characteristics of responders and non responders were similar. Mean age of responders was 65 (SD 12) and 59% were male. There were 193 (79%) patients who never had a PEG as part of their treatment, 30 (12%) who had their PEG removed (median 7 months), and 20 (8%) who still had a PEG (median 34 months). Patients with PEGs reported significant deficits in all UW-QOL domains compared to non-PEG or PEG-removed patients and also reported a much poorer quality of life. The major PEG related problems were not those of discomfort, leakage or blockage, but interference with family life, intimate relationships, social activities, and hobbies. More can be done to counsel and support patients with long-term PEG placement.

A prospective study on C-reactive protein as a prognostic factor for survival time of terminally ill cancer patients

GOALS OF WORK

C-reactive protein (CRP) has been investigated as a predictor of life expectancy in terminal cancer in one previous study. However, the other variables such as patient's symptom or physical examination findings were not considered. The aim of this study is to prove serum CRP level as a predictor of survival time, considering patient's symptoms, physical examination findings, and various serological variables in terminally ill cancer patients with a prospective cohort design.

PATIENTS AND METHODS

Forty-four terminally ill cancer patients were divided into two groups by serum CRP levels and followed up until death. We adjusted the influence of some clinical and laboratory variables on survival by use of Cox's proportional hazard model. Using the stepwise variable selection method, we found the final model. For 19 patients, CRP levels at 2 weeks and a week before death were compared by Wilcoxon signed ranks test.

MAIN RESULTS

All 44 study subjects died during the study period, and the median survival time was 17 days. Survival time of the elevated CRP group (> or =2.2 mg/dl) was found to be significantly shorter than the lower CRP group in univariate analysis (hazard rate = 3.221, P = 0.001). In multivariate analysis, elevated CRP level (> or =2.2 mg/dl) was selected as one of the unfavorable indicators regarding survival. Dyspnea and hyperbilirubinemia were also found significant predictors of shorter life expectancy in the final model. Serum CRP levels were significantly increased between the first and the second week before death.

CONCLUSIONS

Our results showed that serum CRP level can be a useful indicator predictive of survival time of terminally ill cancer patients.

Care of head and neck cancer patients with swallowing difficulties

Cancers of the head and neck include oral cavity, oropharynx, hypopharynx, nasopharynx, larynx, nasal fossa, paranasal sinuses, thyroid, salivary glands and vermilion surfaces (Parker et al, 2004). Incidence of these cancers has risen in the past 30 years, particularly in people under the age of 65 years. Risk factors include cigarette smoking and excessive alcohol abuse. At time of diagnosis patients often present with swallowing difficulties due to tumour location and size. Further oncological treatments such as surgery and radiotherapy can exacerbate these difficulties and cause major nutritional problems. Dietary management in relation to texture modification and nutritional content of meals needs to be addressed as well as feeding strategies recommended by the speech and language therapist. Good communication between all members of the multidisciplinary team is paramount in ensuring that patients have the necessary support, education and quality of life they need.

Cachexia: pathophysiology and clinical relevance

Cachexia causes weight loss and increased mortality. It affects more than 5 million persons in the United States. Other causes of weight loss include anorexia, sarcopenia, and dehydration. The pathophysiology of cachexia is reviewed in this article. The major cause appears to be cytokine excess. Other potential mediators include testosterone and insulin-like growth factor I deficiency, excess myostatin, and excess glucocorticoids. Numerous diseases can result in cachexia, each by a slightly different mechanism. Both nutritional support and orexigenic agents play a role in the management of cachexia.
