Granulocyte-Colony Stimulating Factor (G-CSF) and Macrophage-Colony Stimulating Factor (M-CSF) in Colorectal Cancer Patients
We have investigated the serum level of granulocytecolony stimulating factor (G-CSF) and macrophagecolony stimulating factor (M-CSF) and the commonly accepted tumor markers, such as carcinoembryonic antigen (CEA) and carbohydrate antigen 19–9 (CA 19–9) in colorectal cancer. Additionally, we have defined the diagnostic sensitivity, specificity, positive predictive value, negative predictive value and receiver-operating characteristics (ROC) curve for G-CSF and M-CSF. The serum levels of cytokines were measured in 49 patients with colorectal cancer and in 40 healthy subjects. G-CSF and M-CSF were determined using enzyme-linked immunosorbent assay (ELISA). CEA and CA 19–9 were measured by microparticle enzyme immunoassay. There were significant increases in the level of circulating G-CSF and M-CSF in the colorectal cancer patients compared to the control group. Moreover, the diagnostic sensitivity of M-CSF was higher (65%) than the sensitivity of CEA (31%) and CA 19–9 (20%). The diagnostic specificities of M-CSF and G-CSF were 95%, and the M-CSF predictive value was higher compared with the predictive value of G-CSF. These results suggest a potential role for M-CSF as a tumor
