“…Aksorn et al also recognized novel potential biomarkers that are associated with these events in CCA. These candidates include immunoglobulin heavy chain, translocated in liposarcoma (TLS) and visual system homeobox 2 (VSX2) [ 61 ]. There are many typical and classic markers in CCA, including KRAS , TP53 , PROM1 , CTGF , VIM , DKK1 , SOX2 , SOX17 , MUC1 , PTEN , PTPN14 , c-Met , EGFR , VEGR , CD44 and CDH1 [ 62 , 63 , 64 , 65 , 66 , 67 , 68 , 69 , 70 , 71 , 72 ], but this review specifically focuses on novel evidence from the past five years.…”
