Several factors contribute to inflammation in cancer cachexia, as eicosanoids (7), augmented fatty acid content in the circulation (8), and increased circulation of pro-inflammatory cytokines, among which tumor necrosis factor (TNF), interferon (IFN), interleukin-6 (IL6), and interleukin 1 beta (IL1B) play a prominent role (9). This evidence concerns the gene IL1B and cancer.
