Background: Locally advanced head and neck cancer is managed either by combined surgery and (chemo) radiotherapy or definitive (chemo) radiotherapy, which may deteriorate nutritional status. Previous data have shown that intensive nutritional intervention by a dietician reduces radiation-induced adverse events including weight loss. Objective: To determine if on-demand nutritional counseling (ODC, control group) would be as efficacious as intensive nutritional counseling (INC, experimental group) in patients undergoing (chemo) radiotherapy. Methods: Fifty-eight patients were randomly assigned to receive INC (n = 26) or ODC (n = 32). Outcome measures were nutritional status (PG-SGA), weight loss, handgrip strength (HGS), body composition, and survival. Results: Weight loss and impaired nutritional parameters during oncological treatment were seen equally in both groups (NS). Leaner patients at baseline maintained their weight, while overweight patients lost both weight and handgrip strength during treatment. Disease-free survival (DFS) (median = 43 months) was not affected by weight loss during treatment. Lower baseline HGS and malnutrition were associated with worse DFS (low vs. normal HGS: 15 vs. 42 months; p = 0.05 and malnutrition vs. good nutrition status: 17 vs. 42 months; p = 0.014, respectively). Survival according to low vs. normal HGS in the INC group was 4 vs. 44 months (p = 0.007) and in the ODC group 28 vs. 40 months (p = 0.944). According to malnutrition vs. good nutritional status in the INC group, DFS was 21 vs. 43 months (p = 0.025) and in the ODC group 15 vs. 41 months (p = 0.03). Conclusions: As for our primary endpoint, individualized on-demand nutritional counseling was as efficacious as intensive counseling in preventing deterioration of nutritional status and incidence of malnutrition during (chemo) radiotherapy. This should be verified with larger number of patients. Additional findings were that overweight patients had more severe weight loss, but not poorer survival. Low HGS and malnutrition at baseline were associated with poor survival. Clinical Trial Registration: www.ClinicalTrials.gov, identifier NCT02159508.

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.

Background: Bioelectrical impedance analysis (BIA) is a method for estimating body composition. Clinically the most important parameter is the phase angle (PA), which decreases with progressing malnutrition and is highly predictive for impaired survival and mortality. Aim: To evaluate the association of low PA with the complication rate and length of hospital stay. Material and methods: A cohort of 61 head and neck cancer (HNC) patients underwent BIA prior to surgical treatment. Information on patient and tumour characteristics, treatment, and surgical complications were gathered from hospital records and correlated with BIA results. Results: The median PA was 4.5 (range, 2.7–6.5), and, in 67% of the patients, it was lower than expected. Low PA was associated with longer hospital stay (p = .002) in the whole cohort and in the patient group with radical neck dissections it correlated with a higher surgical complication rate (p = .014), but not with Clavien–Dindo scoring for surgical complications. Conclusions and significance: BIA is a feasible instrument for analysing body composition that reflects nutritional status in cancer patients. Our results show that HNC patients have a low PA at diagnosis. Low PA is associated with a long hospital stay and an increase in the complication rate. BIA can be of clinical value in preoperative risk evaluation.

Chemotherapy-induced mucosal injury of the small intestine may interfere with the enzymes and transporters responsible for the hydrolysis and absorption of dietary carbohydrates causing diarrhoea, abdominal discomfort and pain. The aim of this study was to investigate the association between the consumption of foods rich in FODMAPs (fermentable oligo-, di- and monosaccharides and polyols) and gastrointestinal symptoms in patients receiving adjuvant therapy for colorectal cancer. The patients (n = 52) filled in a 4-day food diary at baseline and during therapy and kept a symptom diary. The intakes of FODMAP-rich foods were calculated as portions and the intakes were divided into two consumption categories. Patients with high consumption of FODMAP-rich foods had diarrhoea more frequently than those with low consumption (for lactose-rich foods the odds ratio (OR) was 2.63, P = 0.03; and for other FODMAP-rich foods 1.82, P = 0.20). Patients with high consumption of both lactose-rich and other FODMAP-rich foods had an over 4-fold risk of developing diarrhoea as compared to those with low consumption of both (OR, 4.18; P = 0.02). These results were confirmed in multivariate models. Conclusion: Consumption of lactose-rich foods results in an increased risk of diarrhoea during adjuvant therapy for colorectal cancer, especially when the consumption of other FODMAP-rich foods is also high.

Nutritional risk is prevalent, and it develops negatively during hospital stay. The aim of this cohort study was to assess the association of nutritional risk with total costs of hospital care, length of stay, and in-hospital mortality. Cross-sectional study with hospitalized patients (n = 3053). Nutritional risk screening 2002 and outcome were investigated. Chi-square, Fisher, and Mann-Whitney tests, univariable and multivariable generalized linear and binary logistic regression models were used. Nutritional risk was detected in 18% (184/1024) of those patients assessed at admission while the number of patients at risk increased 3-fold (47%,152/265) in those screened 14 days after admission (odds ratio 6.25; 95% CI 4.58-8.53, p < 0.001). Nutritionally at-risk patients had 5.6 days longer length of stay (p < 0.001) and 9% higher adjusted total costs compared with non-risk patients (p < 0.001). Adjusted overall risk for in-hospital mortality was 4.4 (95% CI 2.44-7.92, p < 0.001) for patients at nutritional risk. The screening rate was between 52% and 68%, and only 4% of the nutritionally at-risk patients had dietitian consultation during their hospital stay. The number of patients with nutritional risk increased clearly during hospitalization associating with a four times higher in-hospital mortality and substantially increased hospital costs. The results demonstrate that the nutritional risk and its detrimental influence on the outcome increases during hospitalization emphasizing the importance to screen patients at admission and repeated weekly.
