Malnutrition is highly prevalent in people with head and neck cancer (HCN) and is associated with poorer outcomes. However, variation in malnutrition diagnostic criteria has made translation of the most effective interventions into practice challenging. This study aimed to determine the prevalence of malnutrition in a HNC population according to the Global Leadership Initiative on Malnutrition (GLIM) criteria and assess inter-rater reliability and predictive validity. A secondary analysis of data available for 188 patients with HNC extracted from two cancer malnutrition point prevalence studies was conducted. A GLIM diagnosis of malnutrition was assigned when one phenotypic and one etiologic criterion were present. Phenotypic criteria were ≥5% unintentional loss of body weight, body mass index (BMI), and subjective evidence of muscle loss. Etiologic criteria were reduced food intake, and presence of metastatic disease as a proxy for inflammation. The prevalence of malnutrition was 22.6% (8.0% moderately malnourished; 13.3% severely malnourished). Inter-rater reliability was classified as excellent for the GLIM criteria overall, as well as for each individual criterion. A GLIM diagnosis of malnutrition was found to be significantly associated with BMI but was not predictive of 30 day hospital readmission. Further large, prospective cohort studies are required in this patient population to further validate the GLIM criteria.

Neuroendocrine tumors (NETs) have increased in incidence and prevalence over the past 2 decades and affect approximately 170,000 people in the United States alone. Gastroenteropancreatic (GEP) NETs (GEP NET) are a heterogeneous group of rare tumors that have distinct effects on the body due to their tumor location and potential to secrete hormones and peptides. Clinical practice guidelines and consensus guidelines for GEP NETs with regard to best practice for diagnosis, treatment, and medical management are available, but the supportive care needs and optimal nutritional management of patients affected by these unique tumors remain under-researched: evidence to guide clinical practice is lacking. The pathophysiology of the disease and its treatment can cause various symptoms that can have significant effects on vitamin synthesis and absorption, dietary habits, weight change, and appetite. Deficiency of fat-soluble vitamins and niacin exists amongst patients with GEP NET, particularly those on treatment with somatostatin analogs and with serotonin-secreting tumors, respectively. Malnutrition and dietary modification amongst patients with GEP NET is more prevalent than initially thought: up to 25% of inpatients with GEP NET are malnourished. Food intolerance is also reported in up to 40–90% of these patients, though its misdiagnosis is common. This review summarizes the evidence regarding the impact of GEP NET and its treatment on nutritional factors in these patients with emphasis on malnutrition, vitamin deficiencies, dietary intake, and quality of life. Recommendations for clinical practice and research approaches to address these nutritional issues are discussed.

Background: Patients undergoing (chemo) radiotherapy for oropharyngeal squamous cell carcinoma (OPSCC) are at high risk of malnutrition during and after treatment. Malnutrition can lead to poor tolerance to treatment, treatment interruptions, poor quality of life (QOL) and potentially reduced survival rate. Human papillomavirus (HPV) is now known as the major cause of OPSCC. However, research regarding its effect on nutritional outcomes is limited. The aim of this study was to examine the relationship between HPV status and nutritional outcomes, including malnutrition and weight loss during and after patients’ (chemo) radiotherapy treatment for OPSCC. Methods: This was a longitudinal cohort study comparing the nutritional outcomes of HPV-positive and negative OPSCC patients undergoing (chemo) radiotherapy. The primary outcome was nutritional status as measured using the Patient Generated-Subjective Global Assessment (PG-SGA). Secondary outcomes included loss of weight, depression, QOL and adverse events. Results: Although HPV-positive were less likely to be malnourished according to PG-SGA at the beginning of treatment, we found that the difference between malnutrition rates in response to treatment was not significantly different over the course of radiotherapy and 3 months post treatment. HPV-positive participants had significantly higher odds of experiencing >10% weight loss at three months post-treatment than HPV-negative participants (OR = 49.68, 95% CI (2.7, 912.86) p ≤ 0.01). Conclusions: The nutritional status of HPV positive and negative patients were both negatively affected by treatment and require similarly intense nutritional intervention. In acute recovery, HPV positive patients may require more intense intervention. At 3- months post treatment, both groups still showed nutritional symptoms that require nutritional intervention so ongoing nutritional support is essential.

I N TRODUC TIONUpper gastrointestinal (UGI) cancers, specifically oesophageal and gastric cancers, account for almost 10% of new cancer cases globally and approximately 13% of cancer mortality. 1 Surgical resection, with or without neoadjuvant and adjuvant therapies, remains the basis of curative intent treatment for this cancer group. These procedures are significant and not without a high risk of complications, such as anastomotic leak and impacts on morbidity, mortality and quality of life (QOL), which are of significant concern to medical teams. [2][3][4][5] Post major UGI surgery, enteral or parenteral nutrition or the timing or type of oral diet, is a significant consideration known to affect postoperative recovery and the ability to tolerate adjuvant treatment. 5 Despite its importance, there

BackgroundGastroenteropancreatic neuroendocrine tumors (GEP NETs) are a heterogeneous group of tumors with distinct effects on the body due to their potential to secrete hormones and peptides. The incidence and prevalence of GEP NETs in Australia are rising. During 2000-2006, the annual incidence was approximately 3.3 per 100,000 population. To date, there has been development of clinical practice and consensus guidelines for NETs covering best practice for diagnosis, treatment, and medical management; however, the supportive care needs and optimal nutritional management of patients affected by NETs remains underresearched, and evidence to guide clinical practice is lacking. While there is emerging research describing the extent of morbidity in different types of GEP NET patients, little is known about the experience of people affected by these tumors and how nutritional status is impacted by either diagnosis or treatment.ObjectiveThe objective of this study was to explore nutrition-related complications and quality of life of patients diagnosed with a GEP NET and to generate evidence to inform future research and development of nutrition screening and management practices.MethodsPatients diagnosed with a GEP NET at two metropolitan recruitment sites will be invited to participate in a 6-month, mixed-methods longitudinal study. Participants recruited to the study will receive usual care and participate in data collection for the study at 4 time points (at recruitment and 2, 4, and 6 months postrecruitment). Study data will include nutritional status, body weight, fat-free mass, and patient-reported outcome measures (dietitian contact, disease-related symptom presence and severity, dietary habits, health-related quality of life, psychological morbidity, and financial impact). At recruitment and 6 months postrecruitment, complete nutrient testing, including relevant plasma vitamin levels, will also be undertaken. A purposive sample of participants will be invited to take part in semistructured interviews to explore the experience of living with a GEP NET and associated nutrition complications.ResultsEthics approval has been obtained, and study recruitment and data collection are underway.ConclusionsThis study will provide the first in-depth, comprehensive description of nutritional issues in patients with GEP NETs. Results will advance the knowledge of nutritional issues faced by patients with GEP NETs and help inform the development of screening tools and clinical practice guidelines.International Registered Report Identifier (IRRID)DERR1-10.2196/11228

Cross-sectional studies report that up to 25% of people with gastroenteropancreatic neuroendocrine tumours (GEP NET) are malnourished. However, the changes in nutritional status and dietary intake over time are unknown. The present study aimed to comprehensively describe the impact of a GEP NET on nutritional status and quality of life (QOL). Patients diagnosed with a GEP NET were recruited to this prospective longitudinal study on initial attendance to the NET Unit at two tertiary hospitals in Melbourne (VIC, Australia). Patient self-reported QOL measures (European Organisation for Research and Treatment Cancer QLC-C30 and QLC-GINET21) and nutritional outcomes (nutritional status, weight change, fat-free mass [FFM], dietary change, dietitian contact) were collected bi-monthly for six months. Sixty-one patients were recruited (66% male) with a mean ± SD age of 62 ± 12 years, predominantly diagnosed with small intestinal NET and Grade 1/2 disease. Commonly reported symptoms were fatigue (79%), abdominal discomfort (75%) and pain (68%).More patients were malnourished at baseline than at 6 months (29% vs. 13%). Over this 6 months, 48% lost weight, 20% lost ≥ 5% of their body weight, and 62% lost FFM with an average FFM loss of 2.8 kg (95% confidence interval = 2.0, 3.6), consistent with altered body composition. Dietary change was reported by 56% at baseline and 53% at six months, but only 21% consulted a dietitian at baseline and 18% at 6 months. Clinically significant loss of weight and FFM affected many patients with a GEP NET; however, few patients were referred to/or received a consultation with a dietitian. Valid screening practices are needed to identify weight loss and nutrition issues in GEP NET patients, and to facilitate referral to dietitian services.
