2021, Article / Letter to editor (Clinical Nutrition, vol. 40, iss. 5, (2021), pp. 2898-2913)Background: This practical guideline is based on the current scientific ESPEN guidelines on nutrition in cancer patients. Methods: ESPEN guidelines have been shortened and transformed into flow charts for easier use in clinical practice. The practical guideline is dedicated to all professionals including physicians, dieticians, nutritionists and nurses working with patients with cancer. Results: A total of 43 recommendations are presented with short commentaries for the nutritional and metabolic management of patients with neoplastic diseases. The disease-related recommendations are preceded by general recommendations on the diagnostics of nutritional status in cancer patients. Conclusion: This practical guideline gives guidance to health care providers involved in the management of cancer patients to offer optimal nutritional care.

2021, Article / Letter to editor (Journal of Human Nutrition and Dietetics, vol. 34, iss. 1, (2021), pp. 243-254)Background: Cancer cachexia (CC) is a multifactorial syndrome characterised by ongoing skeletal muscle loss that leads to progressive functional impairment driven by reduced food intake and abnormal metabolism. Despite the traditional use of non-volitional weight loss as the primary marker of CC, there is no consensus on how to diagnose and manage CC.
Methods: The aim of this narrative review was to describe and discuss diagnostic criteria and therapeutic approaches for the accredited practicing dietitian with respect to identifying and managing CC.
Results: Available diagnostic criteria for cachexia include the cancer-specific (Fearon and Cachexia Score) and general criteria (Evans and Global Leadership Initiative on Malnutrition). These include phenotypic criteria [weight loss, body mass index, (objective) muscle mass assessments, quality of life] and aetiological criteria (disease burden, inflammation, energy expenditure, anorexia and inadequate food intake) and can be incorporated into the nutrition care process (NCP). This informs the nutrition diagnosis of 'chronic disease- or condition-related malnutrition (undernutrition) as related to increased nutrient needs, anorexia or diminished intake due to CC'. Optimal nutrition care and management of CC is multidisciplinary, corrects for increased energy expenditure (via immunonutrition/eicosapentaenoic acid), suboptimal protein/energy intake and poor nutrition quality of life, and includes a physical exercise intervention. Monitoring of intervention efficacy should focus on maintaining or slowing the loss of muscle mass, with weight change as an alternative gross indicator.
Conclusions: Dietitians and the NCP can play an essential role with respect to identifying and managing CC, focusing on aspects of nutrition screening, assessment and intervention.
2021, Article / Letter to editor (Clinical Nutrition, vol. 40, iss. 6, (2021), pp. 3815-3826)Background & aims: Omega-3 polyunsaturated fatty acid (PUFA) supplementation has been proposed as a potential therapy for cancer-related malnutrition, which affects up to 70% of patients with cancer. The aim of this systematic review and meta-analysis was to examine the effects of oral omega-3 PUFA supplementation on muscle maintenance, quality of life, body weight and treatment-related toxicities in patients with cancer. Methods: Randomised controlled trials in patients with cancer aged 18 years were retrieved from 5 electronic databases: MEDLINE (via PubMed), EMBASE, CENTRAL, CINAHL (via EBSCOhost), and Web of Science, from database inception until 31st of December 2019. The quality of included studies was assessed using the Cochrane risk of bias tool. Trials supplementing >600 mg/d omega-3 PUFA (oral capsules, pure fish oil or oral nutritional supplements) compared with a control intervention for >3 weeks were included. Meta-analyses were performed in RevMan to determine the mean differences (MD) in muscle mass, quality of life and body weight, and odds ratio (OR) for the incidence of treatmentrelated toxicities between omega-3 PUFA and control groups with 95% confidence intervals (CI) and I2 for heterogeneity. Results: We included 31 publications in patients with various types of cancers and degrees of malnutrition. The Cochrane risk of bias tool graded most trials as 'unclear' or 'high' risk of bias. Meta-analyses showed no significant difference between omega-3 PUFA supplements and control intervention on muscle mass, quality of life and body weight. Oral omega-3 PUFA supplements reduced the likelihood of developing chemotherapy-induced peripheral neuropathy (OR: 0.20; 95% CI: 0.10-0.40; p < 0.001; I2 1/4 0%). Conclusion: This systematic review and meta-analysis indicates that oral omega-3 PUFA supplementation does not improve muscle maintenance, quality of life or body weight in patients with cancer, but may reduce the incidence of chemotherapy-induced peripheral neuropathy. Well-designed large-scale randomised controlled trials in homogenous patient cohorts are required to confirm these findings.

2020, Article / Letter to editor (Nutrition & Dietetics: Journal of Dietitians Australia, vol. 77, iss. 4, (2020), pp. 416-425)This position statement describes the recommendations of the Clinical Oncology Society of Australia (COSA) regarding management of cancer-related malnutrition and sarcopenia. A multidisciplinary working group completed a review of the literature, focused on evidence-based guidelines, systematic reviews and meta-analyses, to develop recommendations for the position statement. National consultation of the position statement content was undertaken through COSA members. All people with cancer should be screened for malnutrition and sarcopenia in all health settings at diagnosis and as the clinical situation changes throughout treatment and recovery. People identified as "at risk" of malnutrition or with a high-risk cancer diagnosis or treatment plan should have a comprehensive nutrition assessment; people identified as "at risk" of sarcopenia should have a comprehensive evaluation of muscle status using a combination of assessments for muscle mass, muscle strength and function. All people with cancer-related malnutrition and sarcopenia should have access to the core components of treatment, including medical nutrition therapy, targeted exercise prescription and physical and psychological symptom management. Treatment for cancer-related malnutrition and sarcopenia should be individualised, in collaboration with the multidisciplinary team (MDT), and tailored to meet needs at each stage of cancer treatment. Health services should ensure a broad range of health care professionals across the MDT have the skills and confidence to recognise malnutrition and sarcopenia to facilitate timely referrals and treatment. The position statement is expected to provide guidance at a national level to improve the multidisciplinary management of cancer-related malnutrition and sarcopenia.
