We found that as for the NSCLC patients who reached a good response, the frequencies of MDSCs and CD68+CD163+M2-like macrophages in RT were elevated, in comparison with those for the pre-RT group (Figures 5(a) and 5(b)), while as for the NSCLC patients who reached a poor response, the percentages of two kinds of cells did not have an obvious alteration (Figures 5(c) and 5(d)). The gene discussed is CD68; the disease is non-small cell lung carcinoma.
