Number and frequency of circulating CD14⁺HLA-DR^-/low cells are significantly increased in NSCLC patients. a Absolute counts of monocytes in peripheral blood of healthy controls and NSCLC patients were analyzed by flow cytometry. b Representative dot plots of a healthy control and a NSCLC patient. Whole blood was stained for monocyte markers, including CD14 and HLA-DR. c The percentage of CD14⁺ cells in peripheral blood of healthy controls and NSCLC patients. d The percentage of CD14⁺HLA-DR^-/low cells in peripheral blood CD14⁺ cells in healthy controls and NSCLC patients. e Absolute number of CD14⁺HLA-DR^-/low cells in peripheral blood of healthy controls and NSCLC patients. f The correlation of the percentages of CD14⁺HLA-DR^-/low cells in NSCLC patients with absolute monocyte counts. Healthy controls, n = 35; NSCLC patients, n = 89. Each dot represents one individual. Horizontal bars indicate mean values. All data are shown as mean ±SD. *P < 0.05; **P < 0.01
