Abstract:
Objective To explore the expression of CD14 and TLR4 ( Toll like receptor - 4) in peripheral blood monocytes during the different stage of cancer patients. Methods The expression of TLR4 and CD14 on peripheral blood monocytes was determined by flow cytometry in 50 healthy control group and 80 patients with malignant tumor who were divided into stable group and advanced group according to the change of the size of tumor measured by image and/or the outcome of tumor makers. Results No significant difference was found in the expression level of CD14 between the different stage of malignant tumor ( stable group and advanced group) and healthy controls [ (6. 1600% ? 2. 32217% ,5. 8629% ? 1. 91896% ) vs (5. 5580% ? 1. 42272% ) ]. The expression of TLR4 in stable group had no significant difference as compared with control group [ ( 10. 4444 ? 3. 16225 ) % vs (8. 8780 ? 5. 24612) % ]. The expression of TLR4 in advanced group was significantly higher than that in controls and stable group [ ( 14. 7286 ? 6. 95213 ) % vs ( (8. 8780 ? 5. 24612) % , ( 10. 4444 ? 3. 16225) % ) (P
