Cancer Cachexia: Underlying Mechanisms and Potential Therapeutic Interventions

Abstract

Cancer cachexia, a multifactorial metabolic syndrome developed during malignant tumor growth, is characterized by an accelerated loss of body weight accompanied by the depletion of skeletal muscle mass. This debilitating condition is associated with muscle degradation, impaired immune function, reduced functional capacity, compromised quality of life, and diminished survival in cancer patients. Despite the lack of the known capability of fully reversing or ameliorating this condition, ongoing research is shedding light on promising preclinical approaches that target the disrupted mechanisms in the pathophysiology of cancer cachexia. This comprehensive review delves into critical aspects of cancer cachexia, including its underlying pathophysiological mechanisms, preclinical models for studying the progression of cancer cachexia, methods for clinical assessment, relevant biomarkers, and potential therapeutic strategies. These discussions collectively aim to contribute to the evolving foundation for effective, multifaceted counteractive strategies against this challenging condition.

Molecular Mechanisms of Cachexia: A Review

“…This secretion has the capacity to activate NF-κB, which in turn may contribute to the development of cachexia. The modulation of these cytokines by the JAK-STAT pathway may be a potential therapeutic target for the mitigation of cachexia [45,[138][139][140][141].…”
