PURPOSE OF REVIEW: Cancer cachexia (CC) is a paraneoplastic syndrome (PNS) that is characterised by anorexia, weight loss, fatigue and reduced function. This review explores the molecular drivers of CC and other PNS, identifying shared pathways and highlighting unexplored gaps in research.
RECENT FINDINGS: Recent studies have provided further evidence of pro-inflammatory cytokines, such as interleukin-6 and tumour necrosis factor-α, as central players in both CC and PNS, emphasising their role in systemic effects like muscle wasting, lipolysis and pyrexia. Despite these overlaps between syndromes, cytokine profiles vary across different cancer types with one study highlighting that the interplay between multiple cytokines likely plays a more significant role in cancer phenotypes than individual cytokines. Mediators, such as parathyroid hormone related peptide and vascular endothelial growth factor, which are typically associated with malignant hyperkalaemia and hypertrophic osteoarthropathy respectively, have also been linked to cachexia, suggesting a shared role.
SUMMARY: This review highlights the overlap between CC and other PNS. Exploring these shared mechanisms can bridge research gaps and improve CC treatment strategies. Similar insights may be gained by examining other conditions which overlap with CC such as eating disorders, bariatric surgery and sepsis.
