And up to 80% of people with advanced cancer have weight loss and cachexia. Cachexia is Many side effects of cancer or its treatment may cause appetite loss: Changes to It helps meet the patient's physical, emotional, and social needs. Weight loss and cachexia impair quality of life and prognosis. relationship between health-related quality of life and loss of weight . (such as the small -cell lung cancer patient with rapid weight loss who is eating well). Keywords included qualitative, cancer cachexia, weight loss, anorexia, appetite, albeit the evidence supporting their effectiveness in relation to body weight and .. Due to the significant meaning of food in patients' survival, some family.
Knowledge about the underlying pathophysiology has also increased substantially, particularly with regard to the central role of systemic mediators of inflammation [ 5—8 ]. To sound a caution, we must have the results of large, randomized trials some nearing completion demonstrating safety, efficacy and cost-effectiveness before any of these agents can be considered for clinical practice [ 9 ].
Even so, in anticipation of effective novel therapies, and with our more sophisticated use of existing nutritional support, the early assessment of malnutrition and detection of cachexia is increasingly important. With timely use, there is hope that these developments will alter both patient-centered and oncological outcomes.
As an encouraging model, a recent randomized trial by Temel et al.
Although this study did not involve nutritional support specifically, some of the benefit may have been through improved management of pain and constipation which affect nutritional status.
But how do we best identify patients at risk of malnutrition, weight loss and functional decline? Do we need to add variables to the classification systems already developed? Are particular groups more likely than others to benefit from earlier intervention?
In this context, a group of clinicians with a background in cancer nursing, dietetics, surgery, medical oncology or palliative care and with a publication record in cancer nutrition or cachexia convened in December under the auspices of the European School of Oncology to pool their experience, review the literature and make recommendations summarised in Table 1 as the basis for further discussion.
There was no attempt formally to assign levels of evidence to these recommendations. Footnotes Conflict of Interest: Dietary intake and resting energy expenditure in relation to weight loss in unselected cancer patients.

Cancer cachexia, Weight loss, Malnutrition, Food, Caregiver, Cancer care, Qualitative Introduction Cachexia is a severe medical complication of cancer and considered to be a significant cause of morbidity and mortality affecting up to two-thirds of cancer patients. Cachexia appears to be associated with disease-mediated metabolic disorders, inflammatory responses, and insulin resistance. It is these patients that are often judged by clinicians as being in a cachectic status.
Research in the area of cancer cachexia remains in its infancy, and in particular, evidence of the experience of weight loss and anorexia is limited.
A comprehensive support care model of cancer cachexia should take into account patients' experience and adjustment to the impact of this syndrome.
Focusing on the subjective experience of individuals affected by cachexia would provide insights into an additional layer of the complexity of this syndrome, which is vital for developing interventions for cachexia management. A systematic review of qualitative literature enables to enhance our understanding of this clinical phenomenon through drawing on and analyzing individual qualitative studies. This was undertaken to form the basis of recommendations for use in clinical practice.
Literature search and selection A systematic literature search was undertaken using five electronic databases:
