These data go along with another study, where it has been shown that radiotherapy stimulates tumor cells and stromal cells to produce chemokines, such as CXCL9, CXCL10, CXCL11 and CXCL16, which lead to the infiltration of DCs, macrophages and T cells, further promoting inflammatory tumor microenvironment. This evidence concerns the gene CXCL9 and neoplasm.
