Various studies have reported elevations in granulocyte colony-stimulating factor (G-CSF), granulocyte-macrophage colony-stimulating factor (GM-CSF), and interleukin-6 (IL-6) in tumors of the cervix, pancreatic cancer, hepatocellular carcinoma, and lung cancer [4, 6–8]. Here, IL6 is linked to familial pancreatic carcinoma.
