Aside from the natural role of immune system in controlling tumor growth, ultimate cancer cells hijack the immune system to produce specific cytokines promoting tumor growth, survival and progression.13 Chronic inflammation is also a major driver of cachexia (Table 1), as it affects the function of several tissues such as skeletal muscle, fat, brain and liver.14 Indeed, several pro-inflammatory cytokines promote cachexia: tumor necrosis factor alpha (TNFα), interleukin-6 and -1 (IL-6/IL-1) and interferon gamma.15 Here, IL16 is linked to neoplasm.
