Cancer cachexia syndrome in head and neck cancer patients: part I. Diagnosis, impact on quality of life and survival, and treatment

Local delivery of methotrexate/glycyrrhizin-loaded hyaluronic acid nanofiber for the management of oral cancer

The challenges in treating oral cancer include the limited effectiveness and systemic side effects of conventional chemotherapy and radiation therapy. Hyaluronic acid (HA) based Glycyrrhizin (GL) and Methotrexate (MT) loaded localized delivery systems, specifically nanofiber (NF) based platforms, were developed to address these challenges. The electrospinning method was used for the successful fabrication of a homogenous NF membrane and characterized for morphology, drug entrapment efficiency, tensile strength, and ex-vivo mucoadhesive study. Also, it was evaluated for in-vitro drug release profile, ex-vivo drug permeability, in-vitro anti-inflammatory, apoptosis assay by MTT and flow, and against specific cell lines in order to determine their potential for therapeutic use. Superior tensile breaking force (50 g), mucoadhesive strength of 153 gm/cm2, drug permeability, and releasing properties of designed NF, making them perfect requirements for oral cavity delivery. The anticancer potential of MT in the MTT assay and flow cytometry analysis was significantly increased in oral epidermal carcinoma cell (KB cell) for drug-loaded NF with 63.97 ± 1.99 % apoptosis, at 24 h. With these incorporated, GL with MT in NF had an anti-inflammatory potential, also demonstrated in-vitro and in-vivo. In the Ehrlich Ascites Carcinoma (EAC) induced mice model, the optimal formulation's shows better potential for tumor regression when comparing the developed NF formulation to the drugs. Experimental results show that by lowering mucositis-related inflammation and enhancing the effectiveness of oral cancer treatment, a developed nanofiber-based local drug delivery system offers a feasible strategy for managing oral cancer.

Restoring adiponectin via rosiglitazone ameliorates tissue wasting in mice with lung cancer

AIM

To investigate systemic regulators of the cancer-associated cachexia syndrome (CACS) in a pre-clinical model for lung cancer with the goal to identify therapeutic targets for tissue wasting.

METHODS

Using the Kras/Lkb1 (KL) mouse model, we found that CACS is associated with white adipose tissue (WAT) dysfunction that directly affects skeletal muscle homeostasis. WAT transcriptomes showed evidence of reduced adipogenesis, and, in agreement, we found low levels of circulating adiponectin. To preserve adipogenesis and restore adiponectin levels, we treated mice with the PPAR-γ agonist, rosiglitazone.

RESULTS

Rosiglitazone treatment increased serum adiponectin levels, delayed weight loss, and preserved skeletal muscle and adipose tissue mass, as compared to vehicle-treated mice. The preservation of muscle mass with rosiglitazone was associated with increases in AMPK and AKT activity. Similarly, activation of the adiponectin receptors in muscle cells increased AMPK activity, anabolic signaling, and protein synthesis.

CONCLUSION

Our data suggest that PPAR-γ agonists may be a useful adjuvant therapy to preserve tissue mass in lung cancer.

AMPK as a mediator of tissue preservation: time for a shift in dogma?

Ground-breaking discoveries have established 5'-AMP-activated protein kinase (AMPK) as a central sensor of metabolic stress in cells and tissues. AMPK is activated through cellular starvation, exercise and drugs by either directly or indirectly affecting the intracellular AMP (or ADP) to ATP ratio. In turn, AMPK regulates multiple processes of cell metabolism, such as the maintenance of cellular ATP levels, via the regulation of fatty acid oxidation, glucose uptake, glycolysis, autophagy, mitochondrial biogenesis and degradation, and insulin sensitivity. Moreover, AMPK inhibits anabolic processes, such as lipogenesis and protein synthesis. These findings support the notion that AMPK is a crucial regulator of cell catabolism. However, studies have revealed that AMPK's role in cell homeostasis might not be as unidirectional as originally thought. This Review explores emerging evidence for AMPK as a promoter of cell survival and an enhancer of anabolic capacity in skeletal muscle and adipose tissue during catabolic crises. We discuss AMPK-activating interventions for tissue preservation during tissue wasting in cancer-associated cachexia and explore the clinical potential of AMPK activation in wasting conditions. Overall, we provide arguments that call for a shift in the current dogma of AMPK as a mere regulator of cell catabolism, concluding that AMPK has an unexpected role in tissue preservation.

Cachexia and head and neck squamous cell carcinoma: A scoping review

OBJECTIVE

The objective of this paper was to provide an understanding of cachexia in relation to oral squamous cell carcinoma relevant to oral health care. The paper is a scoping review of aspects of the clinical presentation, aetiology and management of cachexia in relation to oral health and oral health care.

METHODS

A combined search of MEDLINE and EMBASE databases (via OVID) was conducted using the terms ([Head and Neck] OR [Oral Squamous Cell Carcinoma]) AND (Cachexia). Duplicates were removed and results were subsequently limited to studies published between 2000 and 2023, humans and English language. After screening and full-text assessment a total number of 87 studies were included in the review.

RESULTS

It is evident that cachexia is a not uncommon feature of patients with advanced malignancy of the head and neck driven by a multitude of mechanisms, induced by the tumour itself, that lead to reduced nutritional intake, increased metabolism and loss of adipose and skeletal tissue.

CONCLUSION

While a variety of nutritional, physical, psychological and pharmacological interventions may improve quality and duration of life, ultimately the diagnosis of cachexia in relation to head and neck cancer remains an indicator of poor life expectancy.

Impact of nutrition counseling on nutrition status in patients with head and neck cancer undergoing radio- or radiochemotherapy: a systematic review

PURPOSE

In this systematic review, we included randomized controlled trials from 2004 to 2021 to determine the effect of individual dietary counseling for patients with head and neck cancer, specifically, nutritional outcome, morbidity, and quality of life (QOL), during and after chemo- and chemoradiotherapy.

METHODS

In October 2023, a systematic search was conducted searching five electronic databases (Embase, Cochrane, PsychInfo, CINAHL, and Medline) to find studies concerning the use and effectiveness of intensive nutritional care on head and neck cancer patients.

RESULTS

From all 2565 search results, 6 studies with 685 head and neck cancer patients were included in this systematic review. The patients were treated with radiotherapy or radiochemotherapy. The therapy concepts include intensive nutritional support from a dietician. Outcomes were nutritional status, body composition, quality of life, and adverse effect. All studies had low quality, high risk of bias, and reported heterogeneous results: some studies reported significant improved nutrition status, body composition and quality of life, while other studies did not find any changes concerning these endpoints.

CONCLUSION

Due to the very heterogeneous results and methodical limitations of the included studies, a clear statement regarding the effectiveness of intensive nutritional therapy of head and neck cancer patients is not possible. Further well-planned studies are needed.

Mapping the global research landscape on nutritional support for patients with gastrointestinal malignancy: visualization analysis

BACKGROUND

Early nutritional treatment is crucial for the care of patients with operable and advanced gastrointestinal malignancies. Therefore, much research has focused on nutritional support for patients with gastrointestinal malignancies. Therefore, this study aimed to evaluate the global scientific output and activity with respect to nutritional support and gastrointestinal malignancy.

METHODS

We searched in Scopus for publications on gastrointestinal cancer and nutritional assistance published between January 2002 and December 2021. Then, using VOSviewer 1.6.18 and Microsoft Excel 2013, we conducted bibliometric analysis and visualization.

RESULTS

A total of 906 documents were published between 2002 and 2021, including 740 original articles (81.68%) and 107 reviews (11.81%). China ranked first (298 publications, 32.89%), Japan ranked second (86 publications, 9.49%) and the USA ranked third (84 publications, 9.27%). The organisation with the highest number of publications was the Chinese Academy of Medical Sciences & Peking Union Medical College from China, with 14 articles, followed by the Peking Union Medical College Hospital from China and the Hospital Universitari Vall d'Hebron from Spain (13 publications for each). Before 2016, most studies focused on 'nutrition support for patients undergoing gastrointestinal surgery'. However, the latest trends showed that 'nutrition support and clinical outcomes in gastrointestinal malignancies' and 'malnutrition in patients with gastrointestinal cancer' would be more widespread in the future.

CONCLUSIONS

This review is the first bibliometric study to provide a thorough and scientific analysis of gastrointestinal cancer and nutritional support trends worldwide over the last 20 years. This study can aid researchers in decision-making by helping them understand the frontiers and hotspots in nutrition support and gastrointestinal cancer research. Future institutional and international collaboration is expected to accelerate the advancement of gastrointestinal cancer and nutritional support research and investigate more efficient treatment methods.

Muscle mass, quality, and strength; physical function and activity; and metabolic status in cachectic patients with head and neck cancer

BACKGROUND & AIMS

Cancer cachexia is commonly associated with poor prognosis in patients with head and neck cancer (HNC). However, its pathophysiology and treatment are not well established. The current study aimed to assess the muscle mass/quality/strength, physical function and activity, resting energy expenditure (REE), and respiratory quotient (RQ) in cachectic patients with HNC.

METHODS

This prospective cross-sectional study analyzed 64 patients with HNC. Body composition was measured via direct segmental multifrequency bioelectrical impedance analysis, and muscle quality was assessed using echo intensity on ultrasonography images. Muscle strength was investigated utilizing handgrip strength and isometric knee extension force (IKEF). Physical function was evaluated using the 10-m walking speed test and the five times sit-to-stand (5-STS) test. Physical activity was examined using a wearable triaxial accelerometer. REE and RQ were measured via indirect calorimetry. These parameters were compared between the cachectic and noncachectic groups.

RESULTS

In total, 23 (36%) patients were diagnosed with cachexia. The cachectic group had a significantly lower muscle mass than the noncachectic group. Nevertheless, there was no significant difference in terms of fat between the two groups. The cachectic group had a higher quadriceps echo intensity and a lower handgrip strength and IKEF than the noncachectic group. Moreover, they had a significantly slower normal and maximum walking speed and 5-STS speed. The number of steps, total activity time, and time of activity (<3 Mets) did not significantly differ between the two groups. The cachectic group had a shorter time of activity (≥3 Mets) than the noncachectic group. Furthermore, the cachectic group had a significantly higher REE/body weight and REE/fat free mass and a significantly lower RQ than the noncachectic group.

CONCLUSIONS

The cachectic group had a lower muscle mass/quality/strength and physical function and activity and a higher REE than the noncachectic group. Thus, REE and physical activity should be evaluated to determine energy requirements. The RQ was lower in the cachectic group than that in the noncachectic group, indicating changes in energy substrate. Further studies must be conducted to examine effective nutritional and exercise interventions for patients with cancer cachexia.

The Effects of Nutrition Intervention on Postoperative Patients with Tongue Cancer and Floor of Mouth Cancer

The aim of this study is to evaluate the effect of intensive nutrition support on patients with tongue cancer and floor of mouth cancer after surgery at K Hospital, Tan Trieu campus. Study the clinical intervention with a control group. We conducted the intensive nutrition intervention for our patients by giving counseling materials, sample menu and nutritional supplements, while the control group had only advice about dietary regimens. We evaluated a group before and after the intervention, at the same time compare the two groups before and after the intervention. After 1 mo, the intervention group increased 0.51±1.43 kg in comparison with their weight at the beginning; the weight of the control group lost -0.59±2.33 kg; the difference had statistical significance (p=0.025). After 1 and 2 mo of intervention, the rates of the participants without risk of malnutrition in the intervention group increased significantly in comparison with that in the control group; the difference has statistical significance with p=0.001 and p=0.003. In terms of quality of life, patients' problems related to areas including health status, functioning, symptoms of the intervention group improved more greatly than those of the control group. Especially, anorexia symptoms and financial impact were improved well in the intervention group (p=0.033, p=0.018). Nutrition intervention in patients with tongue cancer and floor of mouth cancer has shown a beneficial effect of nutrition counseling and intervention to improve patients' status in terms of nutrition and their quality of life.

Does Human Papillomavirus Infection Influence the Frequency and Severity of Nutritional Disorders in Head and Neck Cancer?

BACKGROUND

About 87% of head and neck cancer (HNC) patients (mostly oropharyngeal cancer-OPC) are infected with human papillomavirus (HPV). Recent studies have demonstrated a significant correlation between HPV infection and nutritional disorders in HNC patients. Therefore, we formed a hypothesis that nutritional disorders or their severity in HNC patients may be associated with the occurrence of HPV infection due to known molecular differences in involved tissue. This literature review aimed to evaluate the influence of HPV infection on the occurrence and severity of nutritional disorders in HNC patients.

MATERIALS AND METHODS

The PubMed database was used to search papers with the keywords "HPV", "HNC", and "nutritional disorders" in different variants and combinations.

CONCLUSIONS

The data available in the discussed papers indicate, among other things, that HPV-positive patients may be at higher risk of malnutrition, critical weight loss, and necessity for gastrostomy after radiotherapy or chemoradiotherapy (C-RT). It should be highlighted that despite some studies demonstrating positive results, currently available data regarding the influence of HPV infection on the occurrence and severity of nutritional disorders in HNC remain limited and inconclusive, and thus further research on this issue is warranted.

Inhibition of epidermal growth factor receptor suppresses parathyroid hormone-related protein expression in tumours and ameliorates cancer-associated cachexia

BACKGROUND

Lung cancer is the primary cause of cancer deaths worldwide. Activation of epidermal growth factor receptor (EGFR) leads to lung cancer progression and poor prognosis while involuntary weight loss remains a major problem. Tumour-derived parathyroid hormone-related protein (PTHrP) emerged as a potential mediator of cachexia. Here, we investigated the modulatory role of EGFR signalling in PTHrP (encoded by Pthlh) gene expression and the impact of this relationship on cancer cachexia.

METHODS

Global gene expression profiles of Lewis lung carcinoma (LLC) cells were analysed. Pthlh mRNA levels were measured by qRT-PCR in LLC cells treated with EGFR ligands and tyrosine kinase inhibitors (TKIs). LLC tumour-bearing mice received EGFR TKI erlotinib for 7 days via intraperitoneal injection or oral gavage. Tumour Pthlh mRNA, weight of fat/muscle tissue, and grip strength were assessed. RNA-seq data from The Cancer Genome Atlas and gene expression analysis tools were used to characterize expression profiles of PTHLH and EGFR along with correlation analysis of PTHLH with EGFR and transforming growth factor alpha (TGFA) in human lung cancer and head and neck squamous carcinoma (HNSC). Survival of lung squamous cell carcinoma (LUSC) and lung adenocarcinoma (LUAD) patients with EGFR gene alterations was analysed in regard to PTHLH expression.

RESULTS

Expression of EGFR ligands, EGFR itself, and PTHrP co-clusters in LLC cells. Activation of EGFR signalling with its ligands significantly increases (3.8-fold, P < 0.0005) while EGFR TKIs significantly decrease (90%, P < 0.0005) Pthlh mRNA levels in LLC cells. Pthlh mRNA drops 65-75% (P < 0.0005) in tumours upon treatment of LLC tumour-bearing mice with erlotinib while their muscle mass and grip strength increase (9.2% P < 0.05, 23% P < 0.005, respectively) compared with tumour-bearing control mice. PTHLH is overexpressed in tumours of LUSC (45.8-fold, P < 0.05) and HNSC (17.5-fold, P < 0.05) compared with normal tissue. PTHLH expression correlates with EGFR and its ligand TGFA in both cancers (LUSC: n = 745, R = 0.32, P < 0.0001 and R = 0.51, P < 0.0001; HNSC: n = 545, R = 0.34, P < 0.001 and R = 0.50, P < 0.001, respectively). High PTHLH mRNA associates with poor overall survival in LUAD patients with activating EGFR mutations (n = 40, log-rank test, P = 0.0451).

CONCLUSIONS

Epidermal growth factor receptor signalling regulates expression of cachexia mediator PTHrP. EGFR inhibition reduces PTHrP expression in LLC tumours and ameliorates cachexia in LLC tumour-bearing mice.

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.

Inflammation Status and Body Composition Predict Two-Year Mortality of Patients with Locally Advanced Head and Neck Squamous Cell Carcinoma under Provision of Recommended Energy Intake during Concurrent Chemoradiotherapy

Only few prospective cohort trials have evaluated the risk factors for the 2-year mortality rate between two patient subgroups with locally advanced head and neck squamous cell carcinoma (LAHNSCC): oral cavity cancer with adjuvant concurrent chemoradiotherapy (CCRT) (OCC) and non-oral cavity cancer with primary CCRT (NOCC), under the recommended calorie intake and investigated the interplay among calorie supply, nutrition–inflammation biomarkers (NIBs), and total body composition change (TBC), as assessed using dual-energy X-ray absorptiometry (DXA). Patients with LAHNSCC who consumed at least 25 kcal/kg/day during CCRT were prospectively recruited. Clinicopathological variables, blood NIBs, CCRT-related factors, and TBC data before and after treatment were collected. Factor analysis was performed to reduce the number of anthropometric and DXA-derived measurements. Cox proportional hazards models were used for analysis. We enrolled 123 patients with LAHNSCC (69 with OCC and 54 with NOCC). The mean daily calorie intake correlated with the treatment interval changes in total body muscle and fat. Patients consuming ≥30 kcal/kg/day had lower pretreatment levels but exhibited fewer treatment interval changes in anthropometric and DXA measurements than patients consuming <30 kcal/kg/day. In the multivariate analysis of the 2-year mortality rate, the prognostic influence of the recommended calorie intake could not be confirmed, but different risk factors (performance status, pretreatment platelet-to-lymphocyte ratio, and treatment interval body muscle changes in patients with OCC; age, pretreatment neutrophil-to-lymphocyte ratio, and body fat storage in patients with NOCC) showed independent effects. Therefore, the inflammation status and body composition, but not the recommended calorie supply, contribute to the 2-year mortality rate for patients with LAHNSCC receiving CCRT.

Nutritional Approach to Cancer Cachexia: A Proposal for Dietitians

Cachexia is one of the most common, related factors of malnutrition in cancer patients. Cancer cachexia is a multifactorial syndrome characterized by persistent loss of skeletal muscle mass and fat mass, resulting in irreversible and progressive functional impairment. The skeletal muscle loss cannot be reversed by conventional nutritional support, and a combination of anti-inflammatory agents and other nutrients is recommended. In this review, we reviewed the effects of nutrients that are expected to combat muscle loss caused by cancer cachexia (eicosapentaenoic acid, β-hydroxy-β-methylbutyrate, creatine, and carnitine) to propose nutritional approaches that can be taken at present. Current evidence is based on the intake of nutrients as supplements; however, the long-term and continuous intake of nutrients as food has the potential to be useful for the body. Therefore, in addition to conventional nutritional support, we believe that it is important for the dietitian to work with the clinical team to first fully assess the patient’s condition and then to safely incorporate nutrients that are expected to have specific functions for cancer cachexia from foods and supplements.

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.

Oral Equilibrium in Cachexia

Oral cancer, a part of head-and-neck cancer (HNC), is associated with a high risk of cancer-associated weight loss causing cachexia which is still an understudied illness. Cachexia is a host-phagocytic syndrome caused by the multiple factors, resulting in the severity of heterogenic fashion. For the current review, a bibliographic search was done in PubMed and other databases for the English articles published from the year 1980 to 2021. Recent studies have revealed that cachexia associated with 35%-60% of all the oral cancer patients is either due to the implication of the tumor or obstruction of food intake for which a strong need for nutritional assistance and hydration is desired. The health of cancer individuals undergoing chemotherapy or bone marrow transplant is negatively affected by poor oral health and reduced dentition status. The impact of a deficient oral condition is not clearly understood to date, possibly due to the limited number of studies and a lack of widely accepted clinical trials to prevent cachexia. The masticatory function of such patients is drastically affected thus contributing to the decreased nutritional status causing wasting of tissues. The aim of this article is to provide substantial evidence that poor oral hygiene with an altered dentition status negatively influences the energy balance of oral cancer patients who experience wasting.

Concurrent Chemoradiotherapy Induces Body Composition Changes in Locally Advanced Head and Neck Squamous Cell Carcinoma: Comparison between Oral Cavity and Non-Oral Cavity Cancer

Few prospective cohort trials have evaluated the difference in treatment-interval total body composition (TBC) changes assessed by dual-energy X-ray absorptiometry (DXA) between two patient subgroups with locally advanced head and neck squamous cell carcinoma (LAHNSCC) receiving concurrent chemoradiotherapy (CCRT): oral cavity cancer with adjuvant CCRT (OCC) and non-oral cavity with primary CCRT (NOCC). This study prospectively recruited patients with LAHNSCC. Clinicopathological variables, blood nutritional/inflammatory markers, CCRT-related factors, and TBC data assessed by DXA before and after treatment were collected. Multivariate linear regression analysis identified the factors associated with treatment-interval changes in body composition parameters, including lean body mass (LBM), total fat mass (TFM), and bone mineral content (BMC). A total of 127 patients (OCC (n = 69) and NOCC (n = 58)) were eligible. Body composition parameters were progressively lost during CCRT in both subgroups. Extremities lost more muscle mass than the trunk for LBM, whereas the trunk lost more fat mass than the extremities for TFM. BMC loss preferentially occurred in the trunk region. Different factors were independently correlated with the interval changes of each body composition parameter for both OCC and NOCC subgroups, particularly mean daily calorie intake for LBM and TFM loss, and total lymphocyte count for BMC loss. In conclusion, treatment-interval TBC changes and related contributing factors differ between the OCC and NOCC subgroups.

Drosophila Larval Models of Invasive Tumorigenesis for In Vivo Studies on Tumour/Peripheral Host Tissue Interactions during Cancer Cachexia

Cancer cachexia is a common deleterious paraneoplastic syndrome that represents an area of unmet clinical need, partly due to its poorly understood aetiology and complex multifactorial nature. We have interrogated multiple genetically defined larval Drosophila models of tumourigenesis against key features of human cancer cachexia. Our results indicate that cachectic tissue wasting is dependent on the genetic characteristics of the tumour and demonstrate that host malnutrition or tumour burden are not sufficient to drive wasting. We show that JAK/STAT and TNF-α/Egr signalling are elevated in cachectic muscle and promote tissue wasting. Furthermore, we introduce a dual driver system that allows independent genetic manipulation of tumour and host skeletal muscle. Overall, we present a novel Drosophila larval paradigm to study tumour/host tissue crosstalk in vivo, which may contribute to future research in cancer cachexia and impact the design of therapeutic approaches for this pathology.

Radiomics predicts risk of cachexia in advanced NSCLC patients treated with immune checkpoint inhibitors

BACKGROUND

Approximately 50% of cancer patients eventually develop a syndrome of prolonged weight loss (cachexia), which may contribute to primary resistance to immune checkpoint inhibitors (ICI). This study utilised radiomics analysis of ¹⁸F-FDG-PET/CT images to predict risk of cachexia that can be subsequently associated with clinical outcomes among advanced non-small cell lung cancer (NSCLC) patients treated with ICI.

METHODS

Baseline (pre-therapy) PET/CT images and clinical data were retrospectively curated from 210 ICI-treated NSCLC patients from two institutions. A radiomics signature was developed to predict the cachexia with PET/CT images, which was further used to predict durable clinical benefit (DCB), progression-free survival (PFS) and overall survival (OS) following ICI.

RESULTS

The radiomics signature predicted risk of cachexia with areas under receiver operating characteristics curves (AUCs) ≥ 0.74 in the training, test, and external test cohorts. Further, the radiomics signature could identify patients with DCB from ICI with AUCs≥0.66 in these three cohorts. PFS and OS were significantly shorter among patients with higher radiomics-based cachexia probability in all three cohorts, especially among those potentially immunotherapy sensitive patients with PD-L1-positive status (p < 0.05).

CONCLUSIONS

PET/CT radiomics analysis has the potential to predict the probability of developing cachexia before the start of ICI, triggering aggressive monitoring to improve potential to achieve more clinical benefit.

Malnutrition screening in head and neck cancer patients with oropharyngeal dysphagia

BACKGROUND & AIMS

Malnutrition in head and neck cancer (HNC) patients is associated with increased morbidity and mortality. The purpose of this study is two-fold: to identify the risk of malnutrition in patients with oropharyngeal dysphagia (OD) secondary to HNC, and to determine the relationship between the risk of malnutrition versus tumor characteristics, treatment modality, time interval (between the end of oncological treatment and swallowing assessment date), level of oral intake, body mass index (BMI), aspiration, pharyngeal pooling, and OD-related quality of life (QoL).

METHODS

The Short Nutritional Assessment Questionnaire (SNAQ) was used to screen patients for the risk of malnutrition. Patients underwent a standardized swallowing examination protocol including an endoscopic evaluation of swallowing.

RESULTS

Seventy-five dysphagic HNC patients were included. Forty-eight percent of the patients presented a high risk of malnutrition using SNAQ. The majority of the patients (81.3%) was on a total oral diet. Moreover, BMI did not appear to be a reliable measure to screen for malnutrition as a normal BMI was often associated with an increased risk of malnutrition on the SNAQ. In contrast, patients who were underweight or overweight did not show an association with a high risk of malnutrition. With the exception of BMI, no other patient and tumor characteristics were found to be associated with the risk of malnutrition.

CONCLUSIONS

This study emphasizes the importance of early nutritional screening in dysphagic HNC patients, as almost half of these patients presented a high risk of malnutrition. Malnutrition screening using SNAQ can identify HNC patients with OD who are at risk of malnutrition and subsequently need to be referred to a dietician for additional nutritional assessment, diagnosis of malnutrition, and nutritional support, even when their BMI is within normal range.

Bioelectrical Impedance Analysis in Patients Undergoing Major Head and Neck Surgery: A Prospective Observational Pilot Study

Background: Head and neck patients are prone to malnutrition. Perioperative fluids administration in this patient group may influence nutritional status. We aimed to investigate perioperative changes in patients undergoing major head and neck surgery and to examine the impact of perioperative fluid administration on body composition and metabolic changes using bioelectrical impedance. Furthermore, we sought to correlate these metabolic changes with postoperative complication rate. In this prospective observational pilot study, bioelectrical impedance analysis (BIA) was performed preoperatively and on postoperative days (POD) 2 and 10 on patients who underwent major head and neck surgeries. BIA was completed in 34/37 patients; mean total intraoperative and post-anesthesia fluid administration was 3682 ± 1910 mL and 1802 ± 1466 mL, respectively. Total perioperative fluid administration was associated with postoperative high extra-cellular water percentages (p = 0.038) and a low phase-angle score (p < 0.005), which indicates low nutritional status. Patients with phase angle below the 5th percentile at POD 2 had higher local complication rates (p = 0.035) and longer hospital length of stay (LOS) (p = 0.029). Multivariate analysis failed to demonstrate that high-volume fluid administration and phase angle are independent factors for postoperative complications. High-volume perioperative fluids administration impacts postoperative nutritional status with fluid shift toward the extra-cellular space and is associated with factors that increase the risk of postoperative complications and longer LOS. An adjusted, low-volume perioperative fluid regimen should be considered in patients with comorbidities in order to minimize postoperative morbidity.

Impact of early nutrition counseling in head and neck cancer patients with normal nutritional status

BACKGROUND

Nutritional counseling is frequently overlooked in cancer patients with normal nutritional status. This study aimed to evaluate the impact of nutritional counseling in head and neck cancer (HNC) patients with normal nutritional status prior to concurrent chemoradiotherapy (CCRT).

METHODS

A total of 243 patients with pretreatment normal nutritional status and locally advanced HNC receiving concurrent chemoradiotherapy (CCRT) at three medical centers were enrolled. All patients were retrospectively allocated into the early (≤ 2 weeks, n = 105, 43.2%), late (> 2 weeks, n = 102, 42.0%), and no nutritional counseling groups (n = 36, 14.8%) according to the time interval between the date of CCRT initiation and the first date of nutritional counseling for comparison.

RESULTS

The 1-year overall survival rates were 95.0%, 87.5%, and 81.3% in the early, late, and no nutritional counseling groups (p = 0.035), respectively. The median body weight changes at end of CCRT were - 4.8% (range, - 13.3 to 8.7%), - 5.6% (range, - 21.9 to 5.6%), and - 8.6% (range, - 20.3 to 2.4%) in patients in the early, late, and no nutritional counseling groups, respectively. The early termination of chemotherapy rates and the incompletion rates of planned radiotherapy were 1.9% and 1.9%, 2.9%, and 2.0%, 13.9%, and 19.4% in patients in the early, late, and no nutritional counseling groups, respectively.

CONCLUSIONS

Our findings strongly suggest that while some HNC patients may have pretreatment normal nutritional status, early nutritional counseling is nevertheless essential for the improvement of treatment tolerance and survival outcome.

Cachexia in Cancer Patients: Systematic Literature Review

Introduction Cachexia in cancer patients, especially in advanced stage, is recently known as an emerging problem. Cachexia occurs in about half of all patients with neoplastic disease. The diagnosis of cachexia needs comprehensive evaluation of body weight and body composition for several months. Cachexia will give negative impacts such as increased mortality, chemotoxicity, and decreased quality of life. Here, we review the current evidence describing the definition, stages, mechanisms, diagnosis and treatment of cachexia in cancer patients.

Methods We identified 75 studies and/or review articles evaluating cachexia and weight loss in cancer patients by searching PubMed and EMBASE databases.

Results Cachexia is reported across all stages and types of cancers. The most recent definition of cachexia is reported in a 2011 paper by International Consensus. The mechanism of cachexia in cancer is complex and involved many factors which elaborate together to produce cachexia. The diagnostic evaluation and cut-off measurement of cachexia, especially in cancer varied across studies. The loss of weight that happens during chemotherapy will make a poor prognosis. Cachexia can worsen chemotherapy toxicity. Combination of dietary modification and exercise with supplementation of medication that control appetite and inflammation are important in the management of cachexia in cancer patients.

Conclusion Patients with cancer are the population at risk for developing cachexia before and after chemotherapy. Cachexia diagnosis needs evaluation of body weight and body composition. Nonpharmacological treatments, such as dietary modification and physical exercise, are the best strategy to reduce cachexia in cancer patients.

Feasibility and Effects of a Supervised Exercise Program Suitable for Independent Training at Home on Physical Function and Quality of Life in Head and Neck Cancer Patients: A Pilot Study

Introduction: Head and neck cancer patients often suffer from physical and cognitive impairments after cancer treatment. During rehabilitation, exercise therapy can improve physical function and quality of life (QoL). Surveys demonstrated patients' preference for home training with low- to moderate-intensity. This study was conducted in order to develope a suitable home-based training program. Therefore, the feasibility and effects of a low- to moderate-intensity exercise intervention on physical functions and QoL were evaluated. Methods: Training was conducted as supervised group training and consisted of mobilization, coordination, resistance, stretching, and relaxation exercises. The intervention lasted 12 weeks with 2 training sessions per week. Feasibility, attendance rate, physical function (eg, range of motion, 6-minute walk test [6MWT]), and QoL (eg, EORTC QLQ-30) were analyzed. Results: Ten out of 12 participants completed the intervention (83%) with an average attendance rate of 83%. Participants showed significant improvements in selected physical functions. For example, head rotation increased by 11.2° (P = .042), walking distance in the 6MWT increased by an average of 43.3 m (P = .010), and the global QoL scale improved by 8.2 points (P = .059). Additionally, there were positive changes in the physical function scale (P = .008), cognitive function scale (P = .015), and social function scale (P = .031) of the EORTC QLQ-30. Conclusion: Data indicate that the exercise program was feasible and had positive effects on physical function and QoL. Future research will analyze the effects of a home-based exercise program on physical function and QoL in a large-scale study.

Yusop NB, Ibrahim Z, Abdul Rahman Z, Jamhuri N. Changes in Nutrition Impact Symptoms, Nutritional and Functional Status during Head and Neck Cancer Treatment

Background: The purpose of this study is to evaluate changes in nutrition impact symptoms (NIS) and nutritional and functional status that occur throughout radiotherapy in head and neck cancer (HNC) patients. Methods: A prospective observational study of HNC inpatients who underwent radiotherapy with or without chemotherapy were recruited to participate. Fifty patients were followed for the periods before, in the middle and at the end of radiotherapy. Nutritional parameters were collected throughout radiotherapy. Results: According to Patient-Generated Subjective Global Assessment (PG-SGA), there was an increase from a baseline of 56% malnourished HNC patients to 100% malnourished with mean weight loss of 4.53 ± 0.41kg (7.39%) at the end of radiotherapy. Nutritional parameters such as muscle mass, fat mass, body mass index, dietary energy and protein intake decrease significantly (p < 0.0001) while NIS score, energy and protein intake from oral nutritional supplements (ONS) increased significantly (p < 0.0001). Hand grip strength did not differ significantly. All HNC patients experienced taste changes and dry mouth that required ONS at the end of treatment. ONS compliance affected the percentage of weight loss (p = 0.013). Conclusions: The intensive nutritional care time point was the middle of RT. The PG-SGA and NIS checklist are useful for monitoring nutrition for HNC patients.

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.

Neuromuscular function and fatigability in people diagnosed with head and neck cancer before versus after treatment

PURPOSE

Treatment for head and neck cancer is associated with multiple side effects, including loss of body mass, impaired physical function and reduced health-related quality of life. This study aimed to investigate the impact of treatment (radiation therapy ± concurrent chemotherapy) on (i) muscle strength, muscle cross-sectional area and patient-reported outcomes, and (ii) central and peripheral alterations during a whole-body exercise task.

METHODS

Ten people with head and neck cancer (4 female; 50 ± 9 years) completed a lab visit before and after (56 ± 30 days) completion of treatment. Participants performed a neuromuscular assessment (involving maximal isometric voluntary contractions in the knee extensors and electrical stimulation of the femoral nerve) before and during intermittent cycling to volitional exhaustion. Anthropometrics and patient-reported outcomes were also assessed.

RESULTS

From before to after treatment, maximal isometric muscle strength was reduced (P = 0.002, d = 0.73), as was potentiated twitch force (P < 0.001, d = 0.62), and muscle cross-sectional area (e.g., vastus lateralis: P = 0.010, d = 0.64). Exercise time was reduced (P = 0.008, d = 0.62) and peripheral processes contributed to a reduction in maximal force due to cycling. After treatment, the severity of self-reported fatigue increased (P = 0.041, r = - 0.65) and health-related quality of life decreased (P = 0.012, r = - 0.79).

CONCLUSION

Neuromuscular function was impaired in patients with head and neck cancer after treatment. Whole-body exercise tolerance was reduced and resulted in predominantly peripheral, rather than central, disturbances to the neuromuscular system. Future research should evaluate strength training after treatment for head and neck cancer, with the overall aim of reducing fatigue and improving health-related quality of life.

Combined Effect of Sarcopenia and Systemic Inflammation on Survival in Patients with Advanced Stage Cancer Treated with Immunotherapy

Background

Sarcopenia and inflammation have been associated with poor survival in patients with cancer. We explored the combined effects of these variables on survival in patients with cancer treated with immunotherapy.

Methods

We performed a retrospective review of 90 patients enrolled on immunotherapy‐based phase I clinical trials at Emory University from 2009 to 2017. Baseline neutrophil‐to‐lymphocyte ratio, monocyte‐to‐lymphocyte ratio, and platelet‐to‐lymphocyte ratio (PLR) were used as surrogates of inflammation. The skeletal muscle index (SMI) was derived from the skeletal muscle density calculated from baseline abdominal computed tomography images. Optimal cutoffs for continuous inflammation biomarkers and SMI were determined by bias‐adjusted log‐rank test. A four‐level risk stratification was used to create low‐risk (PLR <242 and nonsarcopenic), intermediate‐risk (PLR <242 and sarcopenic), high‐risk (PLR ≥242 and nonsarcopenic), and very‐high‐risk (PLR ≥242 and sarcopenic) groups with subsequent association with survival.

Results

Most patients (59%) were male, and the most common cancers were melanoma (33%) and gastrointestinal (22%). Very high‐risk, high‐risk, and intermediate‐risk patients had significantly shorter overall survival (hazard ratio [HR], 8.46; 95% confidence interval [CI], 2.65–27.01; p < .001; HR, 5.32; CI, 1.96–14.43; p = .001; and HR, 4.01; CI, 1.66–9.68; p = .002, respectively) and progression‐free survival (HR, 12.29; CI, 5.15–29.32; p < .001; HR, 3.51; CI, 1.37–9.02; p = .009; and HR, 2.14; CI, 1.12–4.10; p = .022, respectively) compared with low‐risk patients.

Conclusion

Baseline sarcopenia and elevated inflammatory biomarkers may have a combined effect on decreasing survival in immunotherapy‐treated patients in phase I trials. These data may be immediately applicable for medical oncologists for the risk stratification of patients beginning immunotherapeutic agents.

Implications for Practice

Sarcopenia and inflammation have been associated with poor survival in patients with cancer, but it is unclear how to apply this information to patient care. The authors created a risk‐stratification system that combined sarcopenia and platelet‐to‐lymphocyte ratio as a marker of systemic inflammation. The presence of sarcopenia and systemic inflammation decreased progression‐free survival and overall survival in our cohort of 90 patients who received immunotherapy in phase I clinical trials. The data presented in this study may be immediately applicable for medical oncologists as a way to risk‐stratify patients who are beginning treatment with immunotherapy.

The interaction between chronic inflammation and body composition is particularly important in the era of immunotherapy, considering that immune checkpoint inhibitors rely on the host immune system for their efficacy. This article reports on the combined effects of inflammation and sarcopenia on clinical outcomes in patients with solid tumors treated with immunotherapy‐based regimens.

Immunonutrition vs Standard Nutrition for Cancer Patients: A Systematic Review and Meta-Analysis (Part 1)

The aim of this study was to determine the efficacy of immunonutrition vs standard nutrition in cancer patients treated with surgery. Cochrane Central Register of Controlled Trials, EMBASE, MEDLINE, EBSCOhost, and Web of Science were searched. Sixty-one randomized controlled trials were included. Immunonutrition was associated with a significantly reduced risk of postoperative infectious complications (risk ratio [RR] 0.71 [95% CI, 0.64-0.79]), including a reduced risk of wound infection (RR 0.72 [95% CI, 0.60-0.87]), respiratory tract infection (RR 0.70 [95% CI, 0.59-0.84]), and urinary tract infection (RR 0.69 [95% CI, 0.51-0.94]) as well as a decreased risk of anastomotic leakage (RR 0.70 [95% CI, 0.53-0.91]) and a reduced hospital stay (MD -2.12 days [95% CI -2.72 to -1.52]). No differences were found between the 2 groups with regard to sepsis or all-cause mortality. Subgroup analyses revealed that receiving arginine + nucleotides + ω-3 fatty acids and receiving enteral immunonutrition reduced the rates of wound infection and respiratory tract infection. The application of immunonutrition at 25-30 kcal/kg/d for 5-7 days reduced the rate of respiratory tract infection. Perioperative immunonutrition reduced the rate of wound infection. For malnourished patients, immunonutrition shortened the hospitalization time. Therefore, immunonutrition reduces postoperative infection complications and shortens hospital stays but does not reduce all-cause mortality. Patients who are malnourished before surgery who receive arginine + nucleotides + ω-3 fatty acids (25-30 kcal/kg/d) via the gastrointestinal tract during the perioperative period (5-7 days) may show better clinical efficacy.

Efficacy of EPA-enriched supplement compared with standard formula on body weight changes in malnourished patients with head and neck cancer undergone surgery: a randomized study

BACKGROUND

Eicosapentaenoic acid (EPA) containing nutritional supplement can reverse weight loss and increase lean body mass in a perioperative period of patients with head and neck cancer. To study effects of an EPA-enriched supplement compared with a conventional supplement in malnourished patients with head and neck cancer following surgery is primary objective.

METHODS

The patients were randomized into EPA-enriched and standard formula group. The supplements were prescribed 7 days preoperative through 14 days postoperative. Body weight and composition including serum parameters were measured from 7 days preoperative until 4 months postoperative. The hospitalized courses were recorded.

RESULTS

Thirty-one patients in each group consumed EPA-enriched and standard formula supplements. There was no significant body weight or composition changes perioperative. No significant differences in the hospitalized days and postoperative complications was observed.

CONCLUSIONS

Body weight changes in malnourished patients with head and neck cancer following surgery were not influenced by EPA additives to perioperative nutritional supplements.

The association between the Nutrition-Related index and morbidity following head and neck microsurgery

OBJECTIVES/HYPOTHESIS

Despite consensus that preoperative nutritional assessment is of importance in the head and neck surgical oncology population, it remains unclear how exactly malnutrition is associated with perioperative morbidity especially among those undergoing microvascular surgery. We aimed to study this association to help inform preoperative risk stratification, guide the use of nutritional interventions, and ultimately help prevent malnutrition related morbidity.

STUDY DESIGN

Database analysis.

METHODS

Retrospective, linked analysis of the 2011 to 2016 National Surgical Quality Improvement Program. After identifying eligible patients and stratifying according to the Nutrition-Related Index, a univariate screen of preoperative demographic and clinical covariates was performed. Subsequently, propensity score matching was utilized to control for differences in baseline covariates. Perioperative complications and mortality were then analyzed using the propensity score-matched cohorts.

RESULTS

Among 977 identified patients, 276 (28.2%) were malnourished. Malnourished patients had higher rates of comorbidity, were more likely to actively smoke, and were more likely to have primaries in the oropharynx or hypopharynx/larynx. After propensity score matching to control for confounders, malnourished patients had higher rates of pulmonary complications (21.5% vs. 11.6%, P < .01), higher rates of bleeding or need for transfusion (56.6% vs. 43.0%, P < .01), higher rates of venous thromboembolism (3.7% vs. 0.8%, P = .03), and a higher 30-day mortality rates (3.7% vs. 0.0%, P < .01).

CONCLUSIONS

This nationwide analysis finds that 28.2% of patients undergoing surgery for head and neck cancers with free flap reconstruction are malnourished. Malnourishment was found to be independently associated with postoperative pulmonary complications, bleeding or need for transfusion, and 30-day mortality.

Feasibility Outcomes of a Pilot Randomized Clinical Trial to Increase Cruciferous and Green Leafy Vegetable Intake in Posttreatment Head and Neck Cancer Survivors

BACKGROUND

Higher intakes of cruciferous vegetables (CVs) and green leafy vegetables (GLVs) in observational studies are associated with improvements in survival and cancer-related biomarkers in patients diagnosed with head and neck cancer (HNC). These results have yet to be corroborated in a randomized clinical trial (RCT).

OBJECTIVE

Determine the feasibility of implementing a 12-week RCT to increase CV and GLV intake in posttreatment HNC survivors.

DESIGN AND PARTICIPANTS

This was a two-arm RCT conducted among 24 posttreatment HNC survivors. Survivors were recruited from a southeastern, National Cancer Institute-designated Comprehensive Cancer Center between January 2015 and September 2016.

INTERVENTION

There were two groups: (1) an experimental group (n=12) receiving weekly 15- to 30-minute telephone dietary counseling from a registered dietitian nutritionist stressing 2.5 cups per week CVs and 3.5 cups per week GLVs, and (2) an attention control group (n=12) receiving weekly 15- to 30-minute telephone dietary counseling from a registered dietitian nutritionist focusing on general healthy eating for cancer survivors. Participants completed a baseline survey, three 24-hour dietary recalls, phlebotomy, and anthropometric measures prior to randomization and at the end of the 12-week study period. The experimental group also completed weekly vegetable record recalls.

MAIN OUTCOME MEASURES

Primary outcomes included feasibility, recruitment, retention, adherence, and safety. Secondary outcomes included inflammatory markers and carotenoids.

STATISTICAL ANALYSES PERFORMED

Descriptive statistics were generated for demographic, epidemiological, and clinical variables as well as the primary feasibility outcomes. Between- and within-group comparisons of mean serum cytokine and carotenoid levels were performed using appropriate statistical tests depending on their respective distributions for the purpose of generating preliminary effect sizes.

RESULTS

Overall, 350 incident HNC cases were screened for eligibility, and 98 were eligible for study participation. Reasons for ineligibility and exclusion included deceased (n=93); wrong or inactive telephone numbers, or unable to be reached, or lost to follow-up (n=93); not meeting inclusion criteria (n=39); and too ill to participate (n=27). Of the 98 eligible HNC cases, 24 agreed to participate, for an enrollment rate of 25%. The most common reason for nonparticipation was distance (n=48), as participants were asked to report for two on-site assignments. The retention rate was 96%. Mean intervention adherence rates for weekly goals were 67% CV, 74% GLV, and 71% overall. Completion rate of weekly counseling calls was 90%. The experimental group reported an overall mean increase of 5.5 cups GLV and 3.5 cups CV per week from baseline intake, respectively. No significant between- or within-arm differences were observed for inflammatory markers or carotenoids.

CONCLUSION

A posttreatment intervention aimed at increasing CV and GLV intake in HNC survivors is feasible. A larger RCT is needed to assess the efficacy of this intervention on disease outcomes.

Prognostic value of C-reactive protein/albumin ratio for patients with hypopharyngeal and laryngeal cancer undergoing invasive surgery involving laryngectomy

BACKGROUND

The C-reactive protein/albumin (CRP/Alb) ratio has been recently established as a prognostic indicator in various cancer types. However, few reports regarding the prognostic value of the CRP/Alb ratio in head and neck cancer exist. This study aimed to investigate the significance of the CRP/Alb ratio in clinical outcomes after invasive surgery involving laryngectomy for hypopharyngeal and laryngeal cancer.

METHODS

We evaluated 56 patients who underwent total laryngectomy or total pharyngolaryngectomy between 2003 and 2012. Univariate and multivariate analyses were retrospectively performed to examine the prognostic value of the CRP/Alb ratio in these patients.

RESULTS

The optimal cutoff value of the CRP/Alb ratio was 0.32. Multivariate analysis showed that the CRP/Alb ratio was a significant and independent predictor of poor overall and disease-free survival.

CONCLUSION

The CRP/Alb ratio may be a novel and useful indicator for predicting postoperative outcomes in patients with hypopharyngeal and laryngeal cancer.

Local and Systemic Cytokine Profiling for Pancreatic Ductal Adenocarcinoma to Study Cancer Cachexia in an Era of Precision Medicine

Cancer cachexia is a debilitating condition seen frequently in patients with pancreatic ductal adenocarcinoma (PDAC). The underlying mechanisms driving cancer cachexia are not fully understood but are related, at least in part, to the immune response to the tumor both locally and systemically. We hypothesize that there are unique differences in cytokine levels in the tumor microenvironment and systemic circulation between PDAC tumors and that these varying profiles affect the degree of cancer cachexia observed. Patient demographics, operative factors, oncologic factors, and perioperative data were collected for the two patients in the patient derived xenograft (PDX) model. Human pancreatic cancer PDX were created by implanting fresh surgical pancreatic cancer tissues directly into immunodeficient mice. At PDX end point, mouse tumor, spleen and muscle tissues were collected and weighed, muscle atrophy related gene expression measured, and tumor and splenic soluble proteins were analyzed. PDX models were created from surgically resected patients who presented with different degrees of cachexia. Tumor free body weight and triceps surae weight differed significantly between the PDX models and control (P < 0.05). Both PDX groups had increased atrophy related gene expression in muscle compared to control (FoxO1, Socs3, STAT3, Acvr2b, Atrogin-1, MuRF1; P < 0.05). Significant differences were noted in splenic soluble protein concentrations in 14 of 15 detected proteins in tumor bearing mice when compared to controls. Eight splenic soluble proteins were significantly different between PDX groups (P < 0.05). Tumor soluble proteins were significantly different between the two PDX groups in 15 of 24 detected proteins (P < 0.05). PDX models preserve the cachectic heterogeneity found in patients and are associated with unique cytokine profiles in both the spleen and tumor between different PDX. These data support the use of PDX as a strategy to study soluble cachexia protein markers and also further efforts to elucidate which cytokines are most related to cachexia in order to provide potential targets for immunotherapy.

Progressive resistance training in cachectic head and neck cancer patients undergoing radiotherapy: a randomized controlled pilot feasibility trial

BACKGROUND

Cancer cachexia is a prevalent symptom of head and neck neoplasms. The reduction in skeletal muscle mass is one of the main characteristics which can lead to poor physical functioning. The purposes of this pilot randomized controlled trial were to determine the feasibility of progressive resistance training in cachectic head and neck cancer patients during radiotherapy and to explore possible risks and benefits.

METHODS

Twenty cachectic participants with head and neck cancer receiving radiation were randomized to obtain either a machine supported progressive resistance training (n = 10) or usual care (n = 10). The training took place 3 times weekly for 30 min. Intervention included 3 exercises for major muscle groups with 8-12 repetition maximum for 3 sets each. Bioelectrical impedance analysis, hand-held dynamometry, Six-Minute Walk Test and standardized questionnaires for fatigue and quality of life were used for evaluating outcomes at baseline before radiotherapy (t1), after 7 weeks of radiotherapy (t2) and 8 weeks after the end of radiotherapy (t3).

RESULTS

All participants (n = 20) completed the trial. No serious adverse events occurred. At the initial assessment the cachectic patients had already lost 7.1 ± 5.2% of their body weight. General fatigue (score 10.7 ± 3.3) and reduced quality of life (score 71.3 ± 20.6) were prevalent in cachectic head and neck cancer patients even before radiotherapy. An average improvement of weight loading for leg press (+ 19.0%), chest press (+ 29.8%) and latissimus pull-down (+ 22.8%) was possible in the intervention group. Participants had at least 13 training sessions. The outcome measures showed nonsignificant changes at t2 and t3, but a trend for a better course of general fatigue and quality of life at t2 in the intervention group.

CONCLUSIONS

Despite advanced tumor stage and burdensome treatment the intervention adherence is excellent. Progressive resistance training in cachectic head and neck cancer patients during radiotherapy seems to be safe and feasible and may have beneficial effects of general fatigue and quality of life.

Push versus pull gastrostomy in cancer patients: A single center retrospective analysis of complications and technical success rates

PURPOSE

To compare the technical success and complication rates of push versus pull gastrostomy tubes in cancer patients, and to examine their dependence on operator experience.

MATERIALS AND METHODS

A retrospective review was performed of 304 cancer patients (170 men, 134 women; mean age 60.3±12.6 [SD], range: 19-102 years) referred for primary gastrostomy tube placement, 88 (29%) of whom had a previously unsuccessful attempt at percutaneous endoscopic gastrostomy (PEG) placement. Analyzed variables included method of insertion (push versus pull), indication for gastrostomy, technical success, operator experience, and procedure-related complications within 30 days of placement.

RESULTS

Gastrostomy tubes were placed for feeding in 189 patients and palliative decompression in 115 patients. Technical success was 91%: 78% after endoscopy had previously been unsuccessful and 97% when excluding failures associated with prior endoscopy. In the first 30 days, there were 29 minor complications (17.2%) associated with push gastrostomies, and only 8 minor complications (7.5%) with pull gastrostomies (P<0.05). There was no significant difference in major complications (push gastrostomy 5.3%, pull gastrostomy 5.6%). For decompressive gastrostomy tubes, the pull technique resulted in lower rates of both minor and major complications. There was no difference in complications or technical success rates for more versus less experienced operators.

CONCLUSION

Pull gastrostomy tube placement had a lower rate of complications than push gastrostomy tube placement, especially when the indication was decompression. The technical success rate was high, even after a failed attempt at endoscopic placement. Both the rates of success and complications were independent of operator experience.

Drosophila as a Model System to Study Nonautonomous Mechanisms Affecting Tumour Growth and Cell Death

The study of cancer has represented a central focus in medical research for over a century. The great complexity and constant evolution of the pathology require the use of multiple research model systems and interdisciplinary approaches. This is necessary in order to achieve a comprehensive understanding into the mechanisms driving disease initiation and progression, to aid the development of appropriate therapies. In recent decades, the fruit fly Drosophila melanogaster and its associated powerful genetic tools have become a very attractive model system to study tumour-intrinsic and non-tumour-derived processes that mediate tumour development in vivo. In this review, we will summarize recent work on Drosophila as a model system to study cancer biology. We will focus on the interactions between tumours and their microenvironment, including extrinsic mechanisms affecting tumour growth and how tumours impact systemic host physiology.

A turning point: Head and neck cancer patients' exercise preferences and barriers before and after participation in an exercise intervention

This study examined the exercise barriers and preferences of head and neck cancer (HNC) survivors in relation to exercise experience. Participants (n = 22; 46.8% response rate) completed retrospective self-report questionnaires on demographic and medical information, exercise barriers and preferences. A subset of participants then completed semi-structured interviews (n = 18). Participants had previously engaged in the ENHANCE trial during, or immediately following, radiation treatment, an average of 22.1 ± 5.8 months before. Retrospective questionnaires revealed that before ENHANCE participation, lack of interest and time were the primary exercise barriers. After participation, there was a significant decrease in typical barriers including lack of interest (p = .008), exercise not a priority (p = .039) and exercise not in routine (p = .004). Number of barriers experienced after ENHANCE participation was negatively correlated with age, quality of life and minutes of resistance exercise training per week. After ENHANCE participation, significant increases were found in preference for exercising at a cancer centre (p = .031) and with other cancer survivors (p = .016). Four higher order themes emerged inductively from interview data analysis pertaining to preferences (i.e., class format) and three higher order themes regarding barriers (physical, psychological and external). By investigating participants' perspectives after ENHANCE participation, key factors for effective HNC exercise programme design were identified.

Progesterone analogues reduce plasma Epstein-Barr virus DNA load and improve pain control in recurrent/metastatic nasopharyngeal carcinoma patients under supportive care

BACKGROUND

Progesterone analogues, such as megestrol acetate (MA) and medroxyprogesterone (MPA), have been used for the palliative care of cancer cachexia for decades and have proven to increase body weight and improve quality of life and performance status. The objective of this study was to determine the effect of progesterone analogue use on quality of life in terms of pain control, performance status, body weight gain, and Epstein-Barr virus (EBV) DNA load in recurrent/metastatic nasopharyngeal carcinoma (NPC) patients.

METHODS

We retrospectively enrolled 41 patients with locally recurrent or metastatic NPC who received MA or MPA for cachexia management between January 2007 and February 2014. Patients who underwent aggressive treatment with intravenous chemotherapy were excluded. Body weight, performance status, pain score, and plasma EBV DNA load were used to assess quality of life before and after MA/MPA treatment.

RESULTS

Of the 41 patients, 33 patients (80.5%) experienced body weight gain after progesterone analogue intervention. A significant reduction in plasma EBV DNA load was noted after progesterone analogue use (p < 0.001). In addition, median pain and Karnofsky performance scores were also significantly improved in progesterone analogue responders compared with non-responders (4 vs. 1 and 70 vs. 80, respectively; p = 0.004 and p < 0.001, respectively).

CONCLUSION

Progesterone analogues improve quality of life in terms of performance status, pain control, and plasma EBV DNA load in patients with locally recurrent/metastatic NPC under palliative care.

Cachexia at diagnosis is associated with poor survival in head and neck cancer patients

CONCLUSIONS

One third of the patients had cachexia with an association of significantly shorter survival. These results suggest that combining HGS and MAMA seems to be a practical method to screen cachexia in patients with head and neck cancer and may also be used when assessing their prognosis.

OBJECTIVES

The aim of this study was to analyze the hypothesis that cachexia defined as both low mid-arm muscle area (MAMA) and handgrip strength (HGS) is associated with decreased survival in patients with head and neck squamous cell carcinoma (HNSCC).

METHODS

Sixty-five consecutive patients with primary HNSCC were enrolled prior to cancer therapy. Cachexia was defined as low handgrip strength (HGS) and low mid-arm muscle area (MAMA). Nutritional status was assessed by patient-generated subjective global assessment (PG-SGA) and sarcopenia by low MAMA. Biochemical parameters reflecting nutritional status and S-25-OHD were measured.

RESULTS

Cachexia was seen in 31% and sarcopenia in 46% of patients. Altogether, 34% of patients were malnourished. Disease-free survival was 13 months (3-62) in cachectic patients, compared with 66 months (31-78) in non-cachectic patients (p = 0.009). S-25-OHD was 28 nmol/l in cachectic patients, compared with 46 nmol/l in non-cachectic patients (p = 0.009) and prealbumin 187 mg/l and 269 mg/l, respectively (p < 0.001).

Comparison of orofacial pain of patients with different stages of precancer and oral cancer

Orofacial pain impairs a patient's speech, swallowing, eating and interpersonal relations. Thirty-seven patients with a premalignant oral lesion, 124 patients with oral squamous cell carcinoma (OSSC), and 21 patients with a recurrence of OSSC were evaluated for their orofacial pain. The University of California San Francisco Oral Cancer Pain Questionnaire was administered to these patients at their initial visit, before they were prescribed analgesics for pain and before any treatment. Significant differences with respect to orofacial pain between the groups could be evaluatedwere observed. Patients with recurrence had the highest facial pain and patients with precancer had the lowest. Patients with OSSC and recurrence of OSSC reported significant levels of orofacial pain and functional restriction because of pain. Moreover, patients with recurrence of OSSC experienced significantly higher function-related pain, rather than pain qualities. These findings suggest that an important predictor for recurrence of OSSC may be the onset of orofacial pain that is exacerbated during function. The present study examined orofacial pain depending on the disease severity of precancer and oral cancer patients. Earlier recognition of symptoms of OSSC may improve early detection of its recurrence.

Relationship Between the Comprehensive Nutritional Index and the EORTC QLQ-H&N35 in Nasopharyngeal Carcinoma Patients Treated with Intensity-Modulated Radiation Therapy

This study aimed to explore the relationship between the comprehensive nutritional index (CNI) and quality of life in nasopharyngeal carcinoma (NPC) patients receiving intensity-modulated radiation therapy (IMRT). The nutritional index, which includes total lymphocyte count, hemoglobin and albumin levels, body mass index, and usual body weight percentage, was evaluated pre-treatment and post-treatment in patients who underwent IMRT. The quality of life of NPC patients was measured by the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Head and Neck Cancer Module (EORTC QLQ-H&N35) at four time points: pre-treatment, post-treatment, and 3 and 6 mo after IMRT. A comprehensive nutritional model was used to assess the correlation with QLQ-H&N35. The nutritional index decreased significantly post-treatment. The CNI was associated with immunotherapy; the International Union Against Cancer (UICC) stage; concurrent chemotherapy; speech problems, trouble with social contact, feeling ill and having dental problems at pre-treatment; sexuality at 3 mos post-treatment; and sensory problems and xerostomia at 6 mo post-treatment (P < 0.05). The nutritional status and QLQ-H&N35 scores in NPC patients decreased during IMRT. Our study provides an alternative measure of the CNI to improve the QLQ-H&N35 evaluation system for patients with NPC.

Association Between Preoperative Nutritional Status and Postoperative Outcome in Head and Neck Cancer Patients

Head and neck cancer patients treated with surgery often experience significant postoperative morbidities. Administering preoperative nutritional intervention may improve surgical outcomes, but there is currently a paucity of data reviewing the association between preoperative nutritional status and postoperative outcome. It is therefore of importance to investigate this association among head and neck cancer patients. To assess the association between preoperative nutritional status and postoperative outcome in head and neck cancer patients treated with surgery, a retrospective study of 70 head and neck cancer patients who were surgically treated between 2013 and 2014 in a tertiary referral head and neck surgery center in Hong Kong was conducted. Clinical data regarding preoperative nutritional status and postoperative outcome were retrieved from a computer record system. Logistic and linear regressions were used to analyze the appropriate parameters. A higher preoperative albumin level was associated with lower rates of postoperative complications and better wound healing (P < 0.05). In contrast, preoperative body mass index, hemoglobin level, and absolute lymphocyte count did not demonstrate significant associations with postoperative outcome. As high albumin levels are associated with better surgical outcome in head and neck cancer patients, preoperative intervention strategies that boost albumin levels could be considered for improving surgical outcome.

Prevalence and clinical significance of cancer cachexia based on time from treatment in advanced-stage head and neck squamous cell carcinoma

BACKGROUND

The purpose of this study was to identify the prevalence of cancer cachexia and its prognostic impact in patients with advanced head and neck squamous cell carcinoma (HNSCC).

METHODS

The prevalence of cancer cachexia was analyzed according to the follow-up periods during the first year after curative initial treatment. Recurrences, noncancer health events (NCHEs), and cause-specific survival outcomes were also analyzed according to the incidence of cancer cachexia during follow-up.

RESULTS

Cancer cachexia was identified in 22 (6.1%), 148 (41%), 66 (18.4%), and 65 (18.7%) of 361 enrolled patients at pretreatment, immediately after treatment, 6-months after treatment, and 12-months after treatment, respectively. Sustained or newly developed cachexia at 6 and 12 months showed a significant association with recurrence and NCHE occurrence (p < .05). In cause-specific survival analysis, patients with cachexia had a higher probability of cancer-specific death, noncancerous death, and overall death (p < .05).

CONCLUSION

Cachexia prevalence at 6 and 12 months after treatment for HNSCC indicates a higher chance of recurrence, NCHE, and death. © 2016 Wiley Periodicals, Inc. Head Neck 39: 716-723, 2017.

A review of weight loss and sarcopenia in patients with head and neck cancer treated with chemoradiation

Background

Concurrent chemotherapy and radiation (CTRT) improves disease-free survival in locally advanced head and neck cancer but is associated with numerous acute and chronic toxicities resulting in substantial alterations in body mass and composition. We aim to summarize the current evidence on body composition changes experienced by patients undergoing CTRT, examine the impact of these changes on clinical outcomes and address potential interventions aimed at mitigating the loss.

Main Body

Loss of 20 % of pre-CTRT weight predicts poorer treatment tolerance and 30-day mortality. While clinical practice focuses on body weight, emerging data indicates that CTRT causes profound adverse changes in lean body mass (sarcopenia). Higher prevalence of sarcopenia predicts poorer disease-free survival as well as overall survival, lower quality of life and functional performance. The magnitude of CTRT-induced sarcopenia is the equivalent to that observed in a decade of aging in a healthy adult. Alterations in body composition are only explained, in part, by decreased caloric intake; other significant predictors include body mass index, stage, and dysphagia. Lifestyle interventions aimed at preventing loss of whole-body and especially lean mass include nutritional counseling, nutritional supplements, dietary supplements and exercise training. Personalized nutritional counseling has been associated with improvement in quality of life, while the benefits of feeding tube placement are inconsistent. There are inconsistently reported benefits of resistance training in this population.

Conclusion

Patients with head and neck cancer undergoing CTRT therapy experience dramatic shifts in body composition, including sarcopenia, which can negatively impact clinical outcomes. Efforts to understand the magnitude, clinical importance and mechanisms of sarcopenia are needed to inform a more personalized approach to mitigating the body composition changes associated with CTRT.

Overweight/obese status associates with favorable outcome in patients with metastatic nasopharyngeal carcinoma: a 10-year retrospective study

Background

Although the prognostic impact of body mass index (BMI) in patients with non-metastatic nasopharyngeal carcinoma (NPC) had been extensively studied, its effect among metastatic NPC patients remains unknown. The purpose of this study was to evaluate the prognostic effect of BMI in patients with metastatic NPC.

Methods

We retrospectively studied 819 patients who were diagnosed with distant metastasis from NPC and received treatment between 1998 and 2007. The patients were divided into three subgroups according to the World Health Organization classifications for Asian populations: underweight (BMI <18.5 kg/m²), normal weight (BMI 18.5–22.9 kg/m²), and overweight/obese (BMI ≥23.0 kg/m²). The associations of BMI with overall survival (OS) and progression-free survival (PFS) were determined by Cox regression analysis.

Results

Of the 819 patients, 168 (20.5%) were underweight, 431 (52.6%) were normal weight, and 220 (26.9%) were overweight/obese. Multivariate analysis adjusted for covariates showed that overweight/obese patients had a longer OS than underweight patients [hazard ratio (HR), 0.64; 95% confidence interval (CI), 0.49–0.84] and normal weight patients (HR, 0.72; 95% CI, 0.57–0.90); no significant difference in PFS was observed among these three groups (P = 0.407). Moreover, in stratified analysis, no statistically significant differences in the effect of overweight/obese status among different subgroups were observed.

Conclusion

For patients with metastatic NPC, overweight/obese status was associated with longer OS but not longer PFS compared with underweight or normal weight status.

Comparison of the pull and introducer percutaneous endoscopic gastrostomy techniques in patients with head and neck cancer

BACKGROUND AND STUDY AIMS

Percutaneous endoscopic gastrostomy (PEG) in head and neck cancer (HNC) patients is associated with higher complication and mortality rates when compared to a general patient population. The pull technique is still the preferred technique worldwide but it has some limitations. The aim of this study is to compare the pull and introducer PEG techniques in patients with HNC.

PATIENTS AND METHODS

This study is based on a retrospective analysis of a prospectively collected database of 309 patients with HNC who underwent PEG in the Cancer Institute of São Paulo.

RESULTS

The procedure was performed with the standard endoscope in 205 patients and the introducer technique was used in 137 patients. There was one procedure-related mortality. Age, sex and albumin level were similar in both groups. However in the introducer technique group, patients had a higher tumor stage, a lower Karnofsky status, and presented more frequently with tracheostomy and trismus. Overall, major, minor, immediate and late complications and 30-day mortality rates were similar but the introducer technique group presented more minor bleeding and tube dysfunctions.

CONCLUSION

The push and introducer PEG techniques seem to be both safe and effective but present different complication profiles. The choice of PEG technique in patients with HNC should be made individually.

Investigating the clinical significance of body composition changes in patients undergoing chemoradiation for oropharyngeal cancer using analytic morphomics

Background

The purpose is to investigate the clinical significance of body morphomics changes in stage III–IV oropharyngeal cancer patients during concurrent chemoradiotherapy (CRT).

Methods

Fifty patients who underwent CRT were selected for body composition analyses by either availability of pre/post treatment DEXA scans or a novel CT-based approach of body morphomics analysis (BMA). BMA changes (lean psoas and total psoas area) were compared to total lean body mass changes by DEXA scans using two-sample t tests. Pearson correlation was used to compare the BMA measures to head and neck specific quality of life outcomes. Cox hazards model was used to predict mortality and tumor recurrence.

Results

Clinically significant declines in total psoas area and lean body mass of similar magnitude were observed in both BMA and DEXA cohorts after CRT. Loss of psoas area (P < 0.05) was associated with greater frailty and mobility issues (3 out of 15 UWQOL domains). Total psoas area is more sensitive for local recurrence than weight changes and T-stage on multivariate analyses.

Conclusions

BMA specifically evaluating psoas area appears to correlate with head and neck cancer quality of life physical domains. Pre- and post-treatment total psoas area at L4 appears prognostic for tumor recurrence.
