Itoet al(47)and Nonakaet al(48)reported that an HLA-A2-restricted CTL line established from the tumor-infiltrating lymphocytes (TIL) of an HLA-A*02:07-positive patient showed significant cytotoxicities for HLA-A*02:01-, HLA-A*02:06- and HLA-A*02:07-positive cancer cells. This evidence concerns the gene HLA-A and cancer.
