Abstract:

Objective To compare the difference of peripheral blood monocyte M2/M1 ratio between breast cancer patients and healthy subjects,and to investigate the role of peripheral blood monocyte M2/M1 ratio as a circulating tumor marker. Methods Flow cytometry was used to determine peripheral blood monocyte M2/M1 ratio in 89 patients with breast cancer and 53 healthy subjects. The results of carcinoembryonic antigen (CEA) and carbohydrate antigen15-3 (CA15-3) determinations were analyzed comparatively. Results The peripheral blood monocyte M2/M1 ratio in patients with breast cancer was higher than that in healthy subjects(P<0.001). The area under receiver operating characteristic (ROC)curve of peripheral blood monocyte M2/M1 ratio determination was bigger than those of CEA and CA15-3 determinations. Conclusions The application of flow cytometry in determining peripheral blood monocyte M2/M1 ratio for breast cancer patients is of high diagnostic significance. Peripheral blood monocyte M2/M1 ratio may become a new circulating tumor marker for the diagnosis of breast cancer.
