PURPOSE OF REVIEW Cachexia is a complex metabolic syndrome characterized by skeletal muscle and adipose tissue loss and is frequently associated with emaciation, anorexia, systemic inflammation, and metabolic dysfunction. Lack of a clear understanding of the cause of cancer cachexia has impeded progress in identifying effective therapeutic agents. This review summarizes recent publications on t...

The influence of cancer cachexia and chemotherapy and subsequent recovery of skeletal muscle protein mass and turnover was investigated in mice. Cancer cachexia was induced using colon 26 adenocarcinoma, which is characteristic of the human condition, and can be cured with 100% efficacy using an experimental nitrosourea, cystemustine (C(6)H(12)CIN(3)O(4)S). Reduced food intake was not a factor ...

BACKGROUND Current research into the mechanisms of organ atrophy associated with cancer cachexia have centred on the loss of skeletal muscle, as it is one of the most profound physical changes of the disease. However, many patients with cancer cachexia also experience significant atrophy of the heart. The mechanisms causing cardiac tissue wastage in cancer cachexia are largely unknown. However,...

This letter to the editor remarks on recent article by Bouleuc et al. parenteral nutrition for patients with advanced cancer cachexia.

Diabetic neuropathic cachexia is an uncommon peripheral neuropathy associated with diabetes mellitus and characterised by profound weight loss and painful dysaesthesias over the limbs and trunk. The pathophysiological basis of this disorder remains unknown and there have been no published cases of recurrent episodes. A hispanic man who experienced two episodes of diabetic neuropathic cachexia o...

Physical exercise has important effects on secondary prevention or intervention against several diseases. Although there are good reasons to recommend regular physical activity in patient populations, recommending exercise is not a straightforward endeavor in patients with chronic diseases. Cachexia, a severe skeletal muscle wasting syndrome, is often associated with numerous chronic diseases, ...

PURPOSE Ghrelin, a novel growth hormone-releasing peptide,has been shown to cause a positive energy balance by stimulating food intake and inducing adiposity. We sought to investigate the pathophysiology of ghrelin in cachexia associated with lung cancer. EXPERIMENTAL DESIGN Plasma ghrelin level was measured in 43 patients with lung cancer and 21 control subjects. Patients with lung cancer we...

BACKGROUND: Cancer cachexia is the progressive loss of skeletal muscle protein that contributes significantly to cancer morbidity and mortality. Evidence of antioxidant attenuation and the presence of oxidised proteins in patients with cancer cachexia indicate a role for oxidative stress. The level of oxidative stress in tissues is determined by an imbalance between reactive oxygen species prod...

Cancer cachexia/anorexia is a complex syndrome that involves profound metabolic imbalances and is directly implicated as a cause of death in at least 20% to 30% of all cancers. Brown adipose tissue (BAT) plays a key role in thermogenesis and energy balance and potentially contributes to the physiologic perturbations associated with cachexia. In this study, we investigated the impact of cachexia...

In this report we describe an experimental model of cachexia that fulfills the criteria of an early effect with a small tumor mass not related to the growth rate of the tumor, and progressive wasting of muscle and fat without a detectable loss of appetite. C-26.IVX is a cell line derived from murine colon-26 adenocarcinoma which retains the transplantability of the original tumor and induces tr...
