Cachexia progression differs among mouse models of metastatic triple-negative breast cancer.

Cancer-associated cachexia decreases quality of life, reduces therapy response, and diminishes survival prospects. Effective cachexia countermeasures remain a significant unmet need. Research into cancer cachexia has made extensive use of models of colon, lung and pancreatic cancers. However, while cachexia...

Muscle-Specific Strength Better Predicts Physical Performance Decline Than Conventional Metrics: The I-Lan Longitudinal Aging Study.

Muscle-specific strength (MSS), defined as grip strength normalized to arm muscle mass, may better reflect muscle efficiency than grip strength. Despite its potential utility in diagnosing sarcopenia, longitudinal studies evaluating MSS as a predictor of sarcopenia-related outcomes remain limited. This...

Muscle Wasting Disease (MWD) in Cachexia and Sarcopenia

Weight loss is the hallmark of any progressive acute or chronic disease state. In its extreme form, it involves a significant lean body mass (including skeletal muscle), and fat loss. Skeletal muscle provides a fundamental basis for human function, enabling locomotion and respiration. Muscle wasting is related to a poor quality of life and increased morbidity/ mortality.

Two common but distinct conditions characterized by a loss of skeletal muscle mass are sarcopenia and cachexia. Sarcopenia, cachexia, and anorexic disorders (protein-energy malnutrition) represent the major causes of muscle-wasting disorders.

It has been known for millennia that muscle and fat wasting leads to poor outcomes including deaths in chronic disease states.

It is usually accompanied by physical inactivity, decreased mobility, slow gait, and poor physical endurance which are also common features of the frailty syndrome.

Fig. 1 โ€“ Framework for the suggested classification of MWD by disease etiology and disease progression.

Both cachexia and sarcopenia are characterized by an important muscle dysfunction that leads to increased morbidity and mortality.
