RT directly or indirectly activates inflammatory cytokine, e.g., IL-1 and TNF, recruits immune cells, resulting in an intense CD8(+) T-cell tumor infiltrate and a loss of myeloid-derived suppressor cells (70), tumor cells are ablated and tumor antigens are substantially released under high dose radiation, leading to immunogenic cell death and further waterfall-like release of tumor necrosis antigens and adenosine triphosphatase (ATP). This evidence concerns the gene CD8A and neoplasm.
