In the case of treating a metastatic colorectal cancer with adoptive transfer of expanded TILs specific for KRAS (KRAS-G12D) neoantigen presented by HLA-C*08:02, the transferred CD8+ T cells consists of four clonotypes, bearing TCR9a, 9b, 9c and TCR10, at abundance of 49.5%, 6.9%, 0.04% and 19.1% of the total transferred T cells, respectively. This evidence concerns the gene KRAS and metastatic colorectal cancer.
