Cancer Cachexia-Induced Muscle Atrophy
Cancer cachexia is a muscle wasting syndrome that is associated with certain cancers, but most commonly with advanced malignancies. This syndrome arises as a result of tumor-induced metabolic changes, causing the body to break down skeletal muscle and adipose tissue in response to nutritional deficiencies. These changes manifest as severe weight loss, anorexia, asthenia, and anemia, impairing the patient's capacity to tolerate infections, chemotherapy, and radiation treatments (Dhanapal et al., 2022). While research characterizing the multifactorial origins of this syndrome is still ongoing, three recent publications featuring our scientific equipment have made notable advances in the current understanding of this muscle wasting disease, and are discussed in this publication review.
