Pancreatic cancer (PC) remains an incurable disease with few treatment options Recently, promising targets have been identified and novel therapeutic drugs are currently under development in KRAS wild-type PC. It has been reported that KRAS wild-type PC has the genomic alterations such as oncogenic derivers and kinase fusions. NRG1 fusion, which encodes the neuregulin 1 and is the main ligands for ERRB3, has been identified in approximately half of younger patients with PC with KRAS wild-type tumors by RNA sequencing. There are several promising targeted therapies for NRG1 fusion-positive tumors, such as EGFR-tyrosine kinase inhibitor, HER3, HER2 antibodies. BRAF, NTRK, and ALK fusion are also potentially actionable alterations in KRAS wild-type PC and novel therapies targeting certain aberrations have shown activity in clinical trials.
