Factors associated with weight loss during radiotherapy in patients with stage I or II head and neck cancer

Assessment of the Dietary Intake Changes in Patients with Head and Neck Cancer Treated with Radical Radiotherapy

BACKGROUND

Patients during radiotherapy due to head and neck cancers experience a lot of side effects which may have a considerable impact on the patients' ability to meet individual daily energy demands by means of oral diet.

METHODS

The study included 104 head and neck cancer patients who qualified for radical radiotherapy. Radical treatment takes 6 weeks and every week the patients were assessed for dietary intake. The subjects were covered with the constant care of a dietician, received FSMP (food for special medical purposes), and, if necessary, enteral nutrition.

RESULTS

In the first week of treatment, the patients, from the kitchen diet alone, met 91.5% of the energy demand, while in the last week of treatment, only 40.9%. After introducing the FSMP or enteral nutrition, the patients met 120% of the demand in the first week of therapy and 95% in the last week, respectively. The patients who followed the dietary recommendations were characterized by significantly lower weight loss (3.07 kg) compared to non-adherent patients (5.56 kg).

CONCLUSIONS

The used therapy significantly contributed to decreasing nutritional intake in the subsequent weeks of treatment. On the other hand, incorporating FSMP in the diet and enteral nutrition with industrial diets significantly increased the fulfilled energy demand of patients.

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

PURPOSE

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

METHODS

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

RESULTS

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

CONCLUSION

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

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.

Frailty is an independent factor for health-related quality of life in patients with head and neck cancer receiving definitive concurrent chemoradiotherapy

PURPOSE

Health-related quality of life (HRQoL) is associated with treatment-related complications and poor survival in patients with head and neck cancer (HNC). We investigated the effects of frailty on HRQoL in patients with HNC receiving definitive concurrent chemoradiotherapy (CCRT).

METHODS

A total of 461 consecutive patients with locally advanced HNC who received CCRT between 2017 and 2018 at three medical centers in Taiwan were included. Frailty and HRQoL were assessed using the Comprehensive Geriatric Assessment and QLQ-H&N35 before CCRT. The sum score was calculated based on the first 30 questions of QLQ-H&N35. Multivariate analysis was performed to evaluate the impact of frailty on HRQoL.

RESULTS

The overall sum score was 39 (34-49). The sum scores of patients with impairments in 0, 1, 2, 3, and ≥ 4 frailty domains were 34 (32-38), 40 (34-47), 46 (36-55), 48 (41-64), and 56 (50-60), respectively. Patients with impairments in more frailty domains had a higher symptom burden (p for trend < 0.001). Frail patients tended to experience symptoms across all QLQ-H&N35 subscales. Sex, body mass index, tumor type, tumor stage, Eastern Cooperative Oncology Group performance status, and frailty were determinants of HRQoL in the univariate analysis. Frailty was an independent determinant of HRQoL in the multivariate analysis.

CONCLUSION

Routine frailty assessment may serve as a surrogate for the selection of patients with HNC with poor HRQoL before CCRT. Further studies are needed to determine whether appropriate interventions in frail patients would improve their HRQoL during CCRT.

Symptoms of oropharyngeal dysphagia, efficiency, and safety of swallowing in patients after treatment for head and neck cancer

PURPOSE

The aim of this study is to investigate the relation between symptoms and signs of oropharyngeal dysphagia after treatment for head and neck cancer.

METHODS

An observational analytical study with retrospective and prospective components was carried out including 25 adult and elderly patients with head and neck cancer who had completed the treatment at least 3 months before data collection. Data from the Eating Assessment Tool (EAT-10) protocol were analyzed, as well as from the videofluoroscopic swallowing exams. Based on videofluoroscopy, the degree of oropharyngeal dysphagia was classified, as well as the safety and efficiency grade using the DIGEST (Dynamic Imaging Grade of Swallowing Toxicity) scale. Pearson's correlation test was applied, adopting a significance level of 5%.

RESULTS

There was a significant correlation between question 4 of the EAT-10 (swallowing solids takes extra effort) and the efficiency profile (p = 0.004), as well as between question 4 and the DIGEST score (p = 0.002). No significant relation was found between the DIGEST score and EAT-10 total score (p = 0.180) and not even between EAT-10 total score and efficiency (p = 0.129) or safety grade (p = 0.878).

CONCLUSION

In conclusion, no relation was found between most of the dysphagia signs and symptoms investigated, demonstrating that the individual's perception of the swallowing function may not be consistent with the findings of the instrumental evaluation after long-term treatment for head and neck cancer.

Long-term monitoring and predictive factors of critical weight loss among patients with nasopharyngeal carcinoma in a curative treatment setting

PURPOSE

We aimed to determine weight change over time and identify risk factors of critical weight loss among patients with nasopharyngeal carcinoma (NPC).

MATERIALS AND METHODS

In this retrospective study, we investigated weight change over time in 445 patients with NPC who underwent curative treatment. Logistic regression analysis was used to identify possible predictors of critical weight loss.

RESULTS

The incidence of critical weight loss was 67.87%. The long-term monitoring demonstrated a rapid weight loss, especially in the first 2 months of treatment, which continued up to 5 months. Patients with critical weight loss did not regain weight until 3 years. Univariate analysis showed that the following factors were significantly associated with critical weight loss: lower pretreatment body mass index (BMI), tumor stage, subjective global assessment score, Eastern Cooperative Oncology Group (ECOG) score, and enteral tube feeding. Multivariate analysis showed four factors that were associated with a lower critical weight loss: pretreatment BMI < 18.5 kg/m² (p < 0.001, 95% confidence interval [CI] = 0.25 [0.12-0.52]), early tumor stage (p = 0.004, 95% CI = 0.46 [0.27-0.79]), ECOG grade II (p = 0.006, 95% CI = 0.15 [0.04-0.51]), and early prophylactic percutaneous gastrostomy (PEG) tube feeding (p = 0.001, 95% CI = 0.26 [0.12-0.59]).

CONCLUSION

Patients having NPC with critical weight loss showed a significantly rapid decline in their weight in the first 2 months; the weight was persistently less than the baseline value during a 36-month follow-up period. Patients with lower BMI, early-stage cancer, and early prophylactic PEG tube feeding had a significantly lower critical weight loss than those without the abovementioned characteristics.

Addressing symptoms that affect patients' eating according to the Head and Neck Patient Symptom Checklist©

PURPOSE

The purpose of this prospective study was to assess which nutritional impact symptoms (NIS) interfere with oral intake in patients with head and neck cancer (HNC) and how the symptoms interfere with body weight loss, up to 1 year after treatment.

METHODS

This was a prospective study of 197 patients with HNC planned for treatment with curative intention. Body weight was measured before the start of treatment, at 7 weeks after the start of treatment, and at 6 and 12 months after completion of treatment. NIS and NIS interfering with oral intake at each follow-up were examined with the Head and Neck Patient Symptom Checklist^© (HNSC^©).

RESULTS

At 7 weeks of follow-up, patients experienced the greatest symptom and interference burden, and 12 months after treatment the NIS scorings had not returned to baseline. One year after treatment, the highest scored NIS to interfere with oral intake was swallowing problems, chewing difficulties, and loss of appetite. At all 3 follow-ups, the total cumulative NIS and NIS interfering with oral intake were associated with body weight loss. Factors increasing the risk for a body weight loss of ≥ 10% at 12 months after treatment were pain, loss of appetite, feeling full, sore mouth, difficulty swallowing, taste changes, and dry mouth. Women scored higher than men in NIS and NIS interfering with oral intake. Furthermore, during the study period about half of the population had a body weight loss > 5%.

CONCLUSION

Because both nutritional and clinical factors may affect body weight, this study highlights the importance of a holistic approach when addressing the patients' nutritional issues.

Modifying dietary amino acids in cancer patients

Limiting nutrient utilization by cancer cells in order to disrupt their metabolism and suppress their growth represents a promising approach for anti-cancer therapy. Recently, studies demonstrating the anti-neoplastic effects of lowering amino acid (AA) availability have opened up an exciting and quickly growing field of study. Although intracellular synthesis can often provide the AAs necessary to support cancer cells, diet and the tumor microenvironment can also be important sources. In fact, studies carried out in vitro and in animal tumor models have supported the anti-cancer potential of restricting exogenous sources of AAs. However the potential benefit of reducing AA intake in cancer patients requires further investigation. Furthermore, implementation of such an approach clinically, even if proven useful, could be challenging. In the enclosed review, we (1) summarize the pre-clinical studies showing the anti-tumorigenic effects of restricting exogenously available AAs, including through reducing dietary protein, (2) consider the role of microbiota in this process, (3) report on current recommendations for protein intake in cancer patients and studies that applied these guidelines, and (4) propose considerations for studies to test the potential therapeutic benefit of reducing protein/AA consumption in patients with cancer.

Weight Loss in Post-Chemoradiotherapy Head and Neck Cancer Patients

Background: Weight loss is well-known among head and neck (HNC) patients during radiotherapy and could continue after the treatment is completed. Weight monitoring is essential for treatment outcomes and cancer surveillance. The purpose of the study is to evaluate the weight loss during and post-treatment among HNC patients. Methods: A total of 45 out of 50 patients post-treatment were included in this secondary treatment. Data were collected at baseline, at the completion of radiotherapy and one month after completion of radiotherapy. Results: The mean weight loss was 4.53 ± 2.87 kg (7.4%) during treatment and 1.38 ± 2.65 kg (2.1%) post-treatment. There were significant improvements one month after completion of radiotherapy in Patient-Generated Subjective Global Assessment (PGSGA), muscle mass, nutrition impact symptoms (NIS) score, energy and protein from oral intake (p < 0.0001). Energy and protein from oral nutritional supplements (ONS) decreased significantly (p < 0.0001). Conclusions: The results of this study underline the importance of early identification and monitoring post-treatment in HNC patients. The post-treatment recovery stage is very important for HNC patients to ensure a healing process.

Symptomatic Features and Factors Associated With Do-Not-Resuscitate Consent in Advanced Cancer Patients Admitted to Palliative Care Ward

This study aimed to conduct a retrospective cross-sectional study to investigate the prevalence of symptoms and symptom clusters on sociodemographic and disease characteristics, as well as factors associated with Do-Not-Resuscitate (DNR) consent. Advanced cancer patients were enrolled between 2018 and 2020 with available data. Demographic and clinical data were obtained for analysis from Hospital Information System (HIS) in China. Symptom clusters were extracted by hierarchical cluster analysis. Chi-square test and multiple logistic regression were conducted to investigate the prevalence characteristics of symptoms and influencing factors of DNR consent, respectively. 798 advanced cancer patients were enrolled. The most prevalent symptoms were pain (93%), anorexia (36.5%), and sleep disorders (34.2%). High heart rate was associated with poor performance status and more symptoms. Three clusters were extracted: fatigue-related, respiratory-circulatory system, and digestive system symptom clusters. The incidence of symptoms was statistically significant in age, gender, education level, residence, BMI, performance status, distress score, ADL, and primary pain level. The DNR signature rate was 15.5%. Female, distant metastasis, in-ward rescue, and appearance of dyspnea were independent influencing factors of DNR signature.Chinese hospitalized cancer patients had more symptoms burden that were influenced by various demographic characteristics, especially pain and fatigue-related symptoms. Concerning the trajectory of vital signs is important among advanced cancer patients. The DNR signature rate was lower and our finding indicating an urgency to accurately assess the prognosis and give more palliative care education to enhance DNR rates and early signing in Chinese context.

Understanding Cachexia in Head and Neck Cancer

One of the major comorbidities of cancer and cancer therapy is posing a global health problem in cancer cachexia. Cancer cachexia is now considered a multifactorial syndrome that presents with drastic loss of body weight, anorexia, asthenia, and anemia. Head and neck cancer (HNC) patients are at a greater risk for development and severity of cachexia syndrome as there is direct involvement of structures associated with nutritional intake. Yet, the scientific evidence, approach, and management of cachexia in HNCs are yet to be largely explored. The article aims to succinctly review the concepts of cancer cachexia with relevance to HNCs and summarizes the current findings from recent research.

A European survey on the practice of nutritional interventions in head-neck cancer patients undergoing curative treatment with radio(chemo)therapy

PURPOSE

As the practice of nutritional support in patients with head and neck cancer (HNC) during curative radio(chemo)therapy is quite heterogeneous, we carried out a survey among European specialists.

METHODS

A 19-item questionnaire was drawn up and disseminated via the web by European scientific societies involved in HNC and nutrition.

RESULTS

Among 220 responses, the first choice was always for the enteral route; naso-enteral tube feeding was preferred to gastrostomy in the short term, while the opposite for period longer than 1 month. Indications were not solely related to the patient's nutritional status, but also to the potential burden of the therapy.

CONCLUSION

European HNC specialists contextualize the use of the nutritional support in a comprehensive plan of therapy. There is still uncertainty relating to the role of naso-enteral feeding versus gastrostomy feeding in patients requiring < 1 month nutritional support, an issue that should be further investigated.

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.

Nutritional Issues in Head and Neck Cancer Patients

The purpose of this paper is to update the oncologist on the correct approach to the nutritional care of the head and neck cancer patient. Recent scientific contributions on this issue, with a special emphasis on international guidelines and randomised clinical trials (RCTs), are reviewed. The following points are noteworthy: 1. Despite the advances in early diagnosis and modern treatment of head and neck cancer, this tumour still ranks first regarding frequency and severity of weight loss, both at the clinical presentation and during the therapy. 2. This is due to the combination of poor alimentation because of the tumour mass localization, as well as of the presence of an inflammatory response which furtherly drives catabolism. 3. Several studies have shown a very limited role for a dietary counselling unless it includes oral nutritional supplements which are protein or omega-3 fatty acid enriched. 4. A parental nutritional supplementation could represent an acceptable short-term alternative. 5. Long-term nutritional support relies on the use of percutaneous endoscopic gastrostomy (PEG), whereas the role of a prophylactic or "a la demande" PEG is still unsettled and requires further investigations. In conclusion, the nutritional approach using specific formulas and the appropriate route of administration should be part of the therapeutic armamentarium of the modern oncologist.

Nutritional status in patients with head and neck cancer undergoing radiotherapy: a longitudinal study

PURPOSE

Patients with head and neck cancers are susceptible to malnutrition during radiotherapy. This study aimed to determine the changes in the nutritional status and its determinants in patients with head and neck cancer during radiotherapy.

METHODS

This prospective observational study was performed in an outpatient Radiation Oncology clinic with a sample of 54 patients. An interview form (including anthropometric and laboratory parameters), the Patient-Generated Subjective Global Assessment to assess nutritional status, quality of life scales, and toxicity criteria were used for data collection at the baseline, the end of radiotherapy and 1 and 3 months after radiotherapy.

RESULTS

While the majority of the patients (90%) were well nourished at baseline, most of the patients (74%) were malnourished at the end of radiotherapy (p < 0.001). During radiotherapy, patients developed malnutrition, reflected in a decrease in food intake, approximately 5% loss of body weight, a reduction in mid-arm upper circumference and mid-arm muscle mass, and reduced serum protein and albumin levels. The nutritional status was worse in oropharyngeal cancers (p = 0.021), advanced stage (p = 0.004), use of concomitant chemotherapy (p = 0.041), and worse toxicity (p < 0.001). Furthermore, the nutritional status was strongly associated with the quality of life.

CONCLUSIONS

This study demonstrated negative impact of radiotherapy on the nutritional status of patients with head and neck cancer. The study also showed the association of the nutritional status and the quality of life. The nutritional status should be assessed during different periods in the trajectory of treatment due to its significant contribution to the quality of life.

Consensus and clinical recommendations for nutritional intervention for head and neck cancer patients undergoing chemoradiotherapy in Taiwan

Because of the anatomical location, patients with head and neck cancer (HNC) frequently experience dysphagia and malnutrition at the time of diagnosis and these conditions are often exacerbated after chemoradiotherapy. There is an emerging medical need to establish a consensus on nutritional intervention for these patients. A panel of 30 senior physicians and experts from multidisciplinary teams drafted clinical recommendations to improve the management of nutritional interventions in Taiwan and to provide updated treatment strategy recommendations in hope of improving the nutritional status of patients with HNC. This clinical review describes the resulting consensus document, including the impact of malnutrition on clinical outcomes, the role of prophylactic tube feeding, the choice of tube feeding, and the benefit of oral nutritional supplements in patients with HNC undergoing chemoradiotherapy. The outcomes of this review will support clinicians in their efforts to improve the nutritional status of patients with HNC.

Factors which modulate the rates of skeletal muscle mass loss in non-small cell lung cancer patients: a pilot study

PURPOSE

Advanced non-small cell lung cancer (NSCLC) is associated with weight loss which may reflect skeletal muscle mass (SMM) and/or total adipose tissue (TAT) depletion. This study aimed to describe changes in body composition (BC) parameters and to identify the factors unrelated to the tumor which modulate them.

METHODS

SMM, TAT, and the proportion of SMM to SMM + TAT were assessed with computed tomography. Estimates of each BC parameter at follow-up initiation and across time were derived from a mixed linear model of repeated measurements with a random intercept and a random slope. The same models were used to assess the independent effect of gender, age, body mass index (BMI), and initial values on changes in each BC parameter.

RESULTS

Sixty-four patients with stage III or IV NSCLC were reviewed. The mean ± SD decreases in body weight and SMM were respectively 59 ± 3 g/week (P < 0.03) and 7 mm²/m²/week (P = 0.0003). During follow-up, no changes were identified in TAT nor in muscle density or in the proportion of SMM to SMM + TAT, estimated at 37 ± 2% at baseline. SMM loss was influenced by initial BMI (P < 0.0001) and SMM values (P = 0.0002): the higher the initial BMI or SMM values, the greater the loss observed. Weight loss was greater when the initial weight was heavier (P < 0.0001).

CONCLUSION

Our results demonstrate that SMM wasting in NSCLC is lower when initial SMM and BMI values are low. These exploratory findings after our attempt to better understand the intrinsic factors associated with muscle mass depletion need to be confirmed in larger studies.

Association of Body Mass Index With Infectious Complications in Free Tissue Transfer for Head and Neck Reconstructive Surgery

Importance

Elevated body mass index (BMI) has been proposed as a risk factor for morbidity and mortality among patients undergoing surgery. Conversely, an elevated BMI may confer a protective effect on perioperative morbidity.

Objective

To examine whether an elevated BMI is an independent risk factor for perioperative and postoperative infectious complications after free tissue transfer in head and neck reconstructive surgery.

Design, Setting, and Participants

This cohort study included patients undergoing major head and neck surgery requiring free tissue transfer at a tertiary care center. Data were collected for 415 patients treated from January 1, 2007, through December 31, 2014.

Main Outcomes and Measures

The outcome of interest was postoperative infection and complications after head and neck surgery using free flaps. Covariates considered for adjustment in the statistical model included alcohol consumption (defined as >5 drinks per day [eg, 360 mL of beer, 150 mL of wine, or 45 mL of 80-proof spirits]), type 2 diabetes, prior radiotherapy, anesthesia time, hypothyroidism, smoking, American Society of Anesthesiologists classification, antibiotic regimen received (defined as a standard regimen of a first- or second-generation cephalosporin with or without metronidazole hydrochloride vs an alternative antibiotic regimen for patients allergic to penicillin), and primary surgeon. A multiple logistic regression model was developed for the incidence of the infection end point as a function of elevated BMI (>30.0).

Results

Among the 415 patients included in this study (277 men [66.7%] and 138 women [33.2%]; mean [SD] age, 61.5 [13.9] years), type 2 diabetes and use of an alternative antibiotic regimen were found to be independently associated with increased infectious complications after free flap surgery of the head and neck, with estimated odds ratios of 2.78 (95% CI, 1.27-6.09) and 2.67 (95% CI, 1.14-6.25), respectively, in the multiple logistic regression model. However, a high BMI was not found to be statistically significant as an independent risk factor for postoperative infectious complication (estimated odds ratio, 1.19; 95% CI, 0.48-2.92).

Conclusions and Relevance

Elevated BMI does not seem to play a role as an independent risk factor in postoperative complications in free tissue transfer in head and neck surgery.

Exploration of risk factors for weight loss in head and neck cancer patients

Introduction

Head and neck cancer patients receiving radiotherapy can experience a number of toxicities, including weight loss and malnutrition, which can impact upon the quality of treatment. The purpose of this retrospective cohort study is to evaluate weight loss and identify predictive factors for this patient group.

Materials and methods

A total of 40 patients treated with radiotherapy since 2012 at the study centre were selected for analysis. Data were collected from patient records. The association between potential risk factors and weight loss was investigated.

Results

Mean weight loss was 5 kg (6%). In all, 24 patients lost >5% starting body weight. Age, T-stage, N-stage, chemotherapy and starting body weight were individually associated with significant differences in weight loss. On multiple linear regression analysis age and nodal status were predictive.

Conclusion

Younger patients and those with nodal disease were most at risk of weight loss. Other studies have identified the same risk factors along with several other variables. The relative significance of each along with a number of other potential factors is yet to be fully understood. Further research is required to help identify patients most at risk of weight loss; and assess interventions aimed at preventing weight loss and malnutrition.

The humanistic burden of head and neck cancer: a systematic literature review

BACKGROUND

Head and neck cancer (HNC) and its treatment can affect communication, nutrition, and physical appearance, and the global impact of this disease on patients' quality of life may be substantial.

OBJECTIVE

The aim of this systematic literature review was to describe the impact of HNC and its treatment on the physical, emotional, and social well-being of patients over time, by examining longitudinal studies of patient-reported outcomes (PRO) evaluating these domains.

METHODS

Databases (MEDLINE and Embase) were searched to identify studies published in English between January 2004 and January 2014 analyzing the humanistic aspects of HNC in adult patients. Additional relevant publications were identified through manual searches of abstracts from recent conference proceedings.

RESULTS

Of 1,566 studies initially identified, 130 met the inclusion criteria and were evaluated in the assessment. Investigations using a variety of PRO instruments in heterogeneous patient populations consistently reported that PRO scores decrease significantly from diagnosis through the treatment period, but generally recover to baseline in the first year post-treatment. This trend was observed for many functional domains, although some side effects, such as xerostomia, persisted well beyond 1 year. In addition, considerable evidence exists that baseline PRO scores can predict clinical endpoints such as overall and progression-free survival.

CONCLUSIONS

Many aspects of HNC, both disease and treatment specific, profoundly affect patients' quality of life. Improved knowledge of these effects on PRO may allow for more informed treatment decisions and can help physicians to better prepare patients for changes they may experience during therapy. Furthermore, the predictive value of baseline PRO data may enable healthcare providers to identify at-risk patients in need of more intensive intervention.

Nutri-jelly may improve quality of life and decrease tube feeding demand in head and neck cancer patients

Purpose

Eating difficulty is a critical and common problem in head and neck cancer patients undergoing radiotherapy (RT). It leads to poor quality of life and extensive tube feeding use. Nutri-jelly, a food gel with semisolid texture, water-releasing ability, and ready-to-eat by spoon, was recently developed to alleviate the trouble. However, its efficacy was unknown. This study investigated the potential effect of Nutri-jelly on health-related quality of life (HRQOL) and nasogastric tube feeding use.

Methods

A prospective quasi-randomized patients-preference controlled trial was conducted in 74 head and neck cancer patients. Subjects in study and control groups (37 each) had similar baseline HRQOL and body mass index and undergone definitive radiotherapy (25–35 RT fractions, 5,000–7,000 cGy). Only study group received a 200-ml box of Nutri-jelly as daily supplement throughout radiotherapy. HRQOL was scored by validated questionnaires. The use of tube feeding was collected from medical records.

Results

From 11 to 35 RT fractions, the study group maintained higher overall HRQOL score than that of control group (p < 0.0001). Multiple physiologic and psychological aspects of HRQOL especially swallowing difficulty and overall eating problems were significantly improved in study as compared to control group. Promisingly, the percentage of tube feeding use in study group (13.5 %) was dramatically lower than control group (48.6 %).

Conclusions

Continuous supplementation of Nutri-jelly throughout radiotherapy may improve HRQOL and reduce tube feeding demand in head and neck cancer patients who preferred to take them. Nutri-jelly could be an alternative for head and neck cancer patients who have eating difficulty during radiotherapy.

Factors associated with malnutrition in patients with head and neck cancer

CONCLUSIONS

Comorbidities as well as T classification were the primary determinants for the nutritional status of patients with head and neck cancer.

OBJECTIVES

We aimed to elucidate the underlying conditions of malnutrition in patients with head and neck cancer.

METHODS

We retrospectively reviewed 726 patients diagnosed with head and neck cancer between 2004 and 2013. Associations between malnutrition and clinical parameters were assessed using univariate and multivariate analyses.

RESULTS

Median body mass index was 21.5 (range 11.6-38.0). According to World Health Organization criteria, the nutritional status of these patients was classified into four groups: underweight (18%), normal (63%), overweight (17%), and obese (1%). Comorbidities were detected in 40% of patients. Multivariate analysis revealed the following factors to be independent factors associated with malnutrition: advanced T stage, metachronous cancer, collagen disease, gastrointestinal disease, and pulmonary disease.

Weight and body mass index in relation to irradiated volume and to overall survival in patients with oropharyngeal cancer: a retrospective cohort study

Background

Weight loss is a common problem in patients with Squamous Cell Carcinoma of the Head and Neck (SCCHN) treated with radiotherapy (RT). The aims of the present study were to determine if treated volume (TV), as a measure of the radiation dose burden, can predict weight loss in patients with oropharyngeal cancer and to analyze weight loss and body mass index (BMI) in the same patient group in relation to 5-year overall survival.

Methods

The ARTSCAN trial is a prospective, randomized, multicenter trial in patients with SCCHN. Nutritional data from the ARTSCAN trial were analyzed retrospectively using univariate and multivariate statistical methods based on information on percentage weight loss from the start of RT up to five months after the termination of RT (study cohort 1, n = 232) and information on patients’ BMI at the start of RT (study cohort 2, n = 203). TV was defined as the volume of the patient receiving at least 95% of the prescribed dose. TV_{64.6 Gy} encompasses macroscopic tumor and TV_{43.7 Gy} elective lymph nodes of the neck.

Results

TV_{64.6 Gy} and TV_{43.7 Gy} were both significantly correlated with higher weight loss up to five months after the termination of RT in study cohort 1 (p < 0.001 for both). BMI at the start of RT was shown to be a prognostic factor for 5-year overall survival in study cohort 2 but weight loss was not. The hazard ratios and 95% confidence intervals were 3.78 (1.46–9.75) and 2.57 (1.43–4.62) in patients with underweight and normal weight, respectively.

Conclusions

TV can predict weight loss during RT in patients with oropharyngeal cancer regardless of clinical stage. A high BMI (>25 kg/m²) at the start of RT is positively associated with survival in patients with oropharyngeal cancer.

Survivors' experiences of dysphagia-related services following head and neck cancer: implications for clinical practice

BACKGROUND

It is known that people with dysphagia experience a number of negative consequences as a result of their swallowing difficulties following head and neck cancer management (HNC). However their perceptions and experiences of adjusting to dysphagia in the post-treatment phase, and the services received to assist this process, has not been studied.

AIMS

To explore the lived experience of people with dysphagia following non-surgical treatment for HNC and examine their perceptions of service needs.

METHODS & PROCEDURES

A demographically diverse group of 24 people who had received radiotherapy for HNC in the past five years, and experienced dysphagia as a result of treatment, were recruited using maximum variation sampling. Each participant took part in a semi-structured, in-depth interview, where they reflected on their adjustment to, and recovery from dysphagia following treatment for HNC, as well as the dysphagia-related services they received during their treatment. Thematic analysis was used to analyse the transcripts and to identify key themes that emerged from the data.

RESULTS

The main integrative theme was the desire for ongoing access to dysphagia-related services in order to adequately manage dysphagia. Within this integrative theme were five additional themes including: (1) entering the unknown: life after treatment for HNC; (2) making practical adjustments to live with dysphagia; (3) making emotional adjustments to live with dysphagia; (4) accessing support outside the hospital services; and (5) perceptions of dysphagia-related services.

CONCLUSIONS & IMPLICATIONS

The interviews revealed the need for both greater access to services and a desire for services which address the multitude of issues faced by people with dysphagia following HNC in the post-treatment period. Speech and language therapists managing this caseload need to ensure post-treatment services are available and address not only the physical but also the emotional and psychosocial changes impacting people with dysphagia in order to assist them to adjust to, and live successfully with dysphagia. Further research should be conducted to support the development of innovative services and to highlight dysphagia-related survivorship issues to governing bodies/policy makers.

Predictors of weight loss during conformal radiotherapy for head and neck cancers - how important are planning target volumes?

AIMS

Nutritional compromise is common during high dose radiotherapy (RT) or chemoradiotherapy (CRT) for head and neck cancers. We aimed to identify the factors that determine nutritional outcome for head and neck cancer patients during radiotherapy.

METHODS

Data from 103 patients with head and neck cancer treated with highly conformal radiotherapy to doses of 60 Gy or more in 30-33 fractions in the adjuvant or definitive setting was analyzed. All patients received complex 3D conformal radiotherapy (3DCRT) or intensity modulated radiotherapy (IMRT). Patients received regular nutritional counseling and need-based interventions. Their weight was recorded at the beginning and end of radiotherapy. Using univariate and multivariate models we tested possible predictors of weight loss of >5% and NG tube requirement.

RESULTS

The mean weight loss was 3.8%. The incidence of weight loss >5% was 37.9% and NG tube placement was 24.3%. The factors significantly associated with >5% weight loss in the univariate analysis were tumor site (oro-hypopharyngeal vs. others), definitive vs. adjuvant RT; prescription dose of >60 Gy vs. 60 Gy; CRT vs. RT alone; prescription dose planning target volume (PTV) volume >235 cc and total PTV volume >615 cc. Age, sex, T stage, N stage and modality (3DCRT/IMRT) were not significant. In multivariate analysis, the total PTV volume, prescription dose PTV volume and use of chemotherapy were significant after controlling for other factors. Patients could be risk stratified based on the use of CRT and large PTV volumes. Patients with none, one or both factors had a likelihood of >5% weight loss of 0%, 30.3%, and 56.9% (p < 0.001) and likelihood of NG tube placement of 5.3%, 15.2% and 37.3% (p = 0.007).

CONCLUSIONS

It is possible to predict weight loss and NG tube requirements from disease and treatment related factors. PTV volumes are important predictors of nutritional compromise. Risk stratification may enable more focused counseling and identification of patients who require preventive interventions.

Pretreatment body mass index as an independent prognostic factor in patients with locoregionally advanced nasopharyngeal carcinoma treated with chemoradiotherapy: findings from a randomised trial

OBJECTIVE

To investigate the relationship between the pretreatment body mass index (BMI) and the clinical outcomes in patients with locoregionally advanced nasopharyngeal carcinoma treated with combination of chemotherapy and radiotherapy.

METHODS

From August 2002 to April 2005, 400 patients with stage III or stage IVa nasopharyngeal carcinoma were recruited for a randomised clinical trial of induction chemotherapy combined with radiotherapy or concurrent chemoradiotherapy. The patients were divided into four groups of underweight (BMI<18.5kg/m(2)), normal weight (BMI 18.5-22.9kg/m(2)), overweight (BMI 23.0-27.4kg/m(2)) or obese (BMI≥27.5kg/m(2)) according to the World Health Organization classifications for Asian populations. The differences in the long-term survival, of these four BMI groups were analysed.

RESULTS

The 5-year failure-free survival rates for the underweight, normal weight, overweight and obese groups were 44%, 61%, 68% and 73%, respectively (p=0.014), and the 5-year overall survival rates were 51%, 68%, 80% and 72% (p=0.001), respectively. BMI was a strongly favoured prognostic factor of overall survival and failure-free survival in a Cox regression model.

CONCLUSIONS

Pretreatment body mass index was a simple, reliable independent prognostic factor for patients with locoregionally advanced nasopharyngeal carcinoma treated with chemoradiotherapy.
