On the other hand, pancreatic cancers with wild-type KRAS, although rare, account for only about 5% of all cases; BRAF and EGFR gene mutations and some fusion genes (FGFR, ALK, NTRK, NRG1, etc.)have also been reported to be detected at a relatively high frequency [83]. This evidence concerns the gene KRAS and pancreatic neoplasm.
