Circulating MDSC cells before and after CRT. PBMCs from 20 patients treated with CRT for lung or head and neck cancer were taken before CRT and 1 month after. HLA-DR^low Lineage⁻ CD33⁺CD14⁺CD11b⁺ MDSC were analyzed by flow cytometry. A and D Representative plots for MDSC (A) in two patients. B MDSC rates variation after CRT, lines in red representing significant increase (> 20%) from baseline (n = 20). C MDSC rates before and after CRT (n = 20). Results are shown as mean (standard deviation). ns, not significant (Wilcoxon test)
