We found that MDSCs were correlated positively with IL-1ra (r = 0.59, p = 0.0161), MIP-1β (r = 0.4939, p = 0.0516), TIMP-2 (r = 0.5575, p = 0.0248), and TNF RI (r = 0.504, p = 0.0465) in NSCLC patients of the RT group (Figures 8(a)–8(d)). This evidence concerns the gene TIMP2 and non-small cell lung carcinoma.
