CD68 and non-small cell lung carcinoma: We found that the percentages of peripheral MDSCs and CD68+CD163+M2-like macrophages were significantly elevated in NSCLC patients of the pre-RT and RT groups compared to the HC group, while the proportions of MDSCs and CD68+CD163+M2-like macrophages were decreased in NSCLC patients of the post-RT group, in comparison with the RT group.
