Ghrelin as a Promising Therapeutic Option for Cancer Cachexia

Cachexia is a devastating complication of cancer and an important cause of morbidity and mortality and can have a great effect on quality of life, and sense of self-esteem. Unfortunately; there is no standard cure available for cancer cachexia. Ghrelin; a 28 amino acid orexigenic gut hormone and its mimetics have shown potential benefits in reversing the breakdown of protein and weight loss in catabolic states like cancer cachexia. Ghrelin has effects on several vital pathways in the regulation of appetite, and composition of the body. It increases the secretion of growth hormone and reduces energy expenditure. It plays an important role in regulation of processes associated with cancer and antagonizing protein breakdown in catabolic conditions such as cancer cachexia. Additionally, ghrelin has anti-inflammatory, anti-apoptotic and anxiolytic effects. Administration of ghrelin for short-term has been found to be well-tolerated and safe. These versatile actions of ghrelin and its safety can render it as a potentially useful novel therapy for patients with cancer cachexia. However; there is a need to generate more evidence to support the use of ghrelin in the management of cancer cachexia.
