Several studies have reported the clonal expansion of tumor-infiltrating lymphocytes specific to TAAs, such as Melan-A, MART-1, and NY-ESO-1, in patients with solid tumors [30–32] and WT1-specific CD8+ T cells in the PB and BM of patients with AML [19, 33]. This evidence concerns the gene CD8A and acute myeloid leukemia.
