NCIt definition : A recombinant therapeutic agent which is chemically identical to or similar to the
endogenous cytokine tumor necrosis factor-alpha with antineoplastic properties. Tumor
necrosis factor-alpha binds to and activates death receptors on the cell surface,
resulting in apoptosis and cell death by the p53-independent extrinsic pathway. This
agent also disrupts tumor vascularization. (NCI04);
