We detected several preliminary cytokines and growth factors using BD CBA technology and observed that both pro-inflammatory and anti-inflammatory cytokines, including IL-1β, IL-2, IL-4, IL-6, IL-8, IL-10, IL-17A, TNF, VEGF, and TGF-β, were expressed at higher levels in tumour sera. This evidence concerns the gene CXCL8 and neoplasm.
