Background:Weight loss remains significant in patients with head and neck cancer, despite prophylactic gastrostomy and intensive dietary counseling. The aim of this study was to improve outcomes utilising an early nutrition intervention.Methods:Patients with head and neck cancer at a tertiary hospital in Australia referred for prophylactic gastrostomy prior to curative intent treatment were eligible for this single centre randomised controlled trial. Exclusions included severe malnutrition or dysphagia. Patients were assigned following computer-generated randomisation sequence with allocation concealment to either intervention or standard care. The intervention group commenced supplementary tube feeding immediately following tube placement. Primary outcome measure was percentage weight loss at three months post treatment.Results:Recruitment completed June 2015 with 70 patients randomised to standard care (66 complete cases) and 61 to intervention (56 complete cases). Following intention-to-treat analysis, linear regression found no effect of the intervention on weight loss (10.9±6.6% standard care vs 10.8±5.6% intervention, P=0.930) and this remained non-significant on multivariable analysis (P=0.624). No other differences were found for quality of life or clinical outcomes. No serious adverse events were reported.Conclusions:The early intervention did not improve outcomes, but poor adherence to nutrition recommendations impacted on potential outcomes.

Aims:The aim of this paper was to update the evidence-based practice guidelines for the nutritional management of patients receiving radiation therapy and broaden the scope to include chemotherapy. Methods: The following databases were searched using a range of keywords: Cochrane Database, CENTRAL, MEDLINE (via Ebscohost), EMBASE, CINAHL (Ebscohost), Web of Science, Health Source: Nursing/Academic Edition and PubMed. Relevant papers (n = 47) were reviewed by at least two members of the steering committee and assigned a level of evidence and a quality rating. Results: There were no new published randomised controlled trials (RCTs) of nutrition intervention in radiation therapy. Most statements in the previous radiation therapy guidelines have strong evidence supporting nutrition intervention. There were 12 studies in chemotherapy including five RCTs. While these studies provided strong evidence that simple nutrition intervention improves nutritional outcomes such as dietary intake and weight, they did not find an improvement in quality of life or survival. Several RCTs found no benefits of nutrition support in patients undergoing chemotherapy. None of the RCTs in chemotherapy used medical nutrition therapy (MNT) as the intervention, but rather simple dietary advice and/or supplements. Conclusions:The evidence to support nutrition intervention in patients receiving radiation therapy remains strong. However, the benefits of nutrition intervention in chemotherapy are less clear. Further studies are required to evaluate the impact of MNT as opposed to simple dietary advice in chemotherapy patients. This update contributes to a move towards comprehensive evidence-based guidelines for the nutritional management of patients with cancer.

Clinically significant weight loss was still prevalent in this population despite proactive interventions. Predictors of weight loss support the evidence-based guidelines' risk categories, and adherence was important to improve outcomes. Further research is required to determine the impact of significant weight loss in patients with high body mass index (BMI).

The risk categories in the guidelines are valid to assist early identification of swallowing and nutritional risk and guide decision-making on proactive gastrostomy tube insertion.

Prophylactic gastrostomy tubes in patients with high-risk head and neck cancer resulted in a significant decrease in hospital admissions and length of stay, and led to increased bed availability.

The results of this study confirm that the updated high-risk category in the protocol for the swallowing and nutrition management of patients with head and neck cancer remains valid to predict proactive gastrostomy in a mixed population receiving helical intensity-modulated radiotherapy and 3-D conformal radiotherapy. The protocol has an improved sensitivity and specificity and hence remains just as relevant for advanced techniques of radiation treatment delivery.

Cancer-related malnutrition and sarcopenia have severe negative consequences including reduced survival and reduced ability to complete treatment. This study aimed to determine the awareness, perceptions and practices of Australian oncology clinicians regarding malnutrition and sarcopenia in people with cancer. MethodsA national cross-sectional survey of Australian cancer clinicians was undertaken between November 2018 and January 2019. The 30-item online purpose-designed survey was circulated through professional organisations and health services. ResultsThe 111 participants represented dietetic (38%), nursing (34%), medical (14%) and other allied health (14%) clinicians. Overall, 86% and 88% clinicians were aware of accepted definitions of malnutrition and sarcopenia, respectively. Perception of responsibility for identification of these
