Popis: Pancreatic ductal adenocarcinoma (PDAC) is one of the most lethal cancers, with a 5-year survival of 8%. Current therapeutic regimens are largely ineffective and underscore the need for novel treatment strategies. Chromosomal rearrangements involving the anaplastic lymphoma kinase (ALK) gene have been identified in several neoplasms. In addition, ALK protein inhibitors have proven efficacy in patients with ALK-rearranged tumors. However, ALK translocations in PDAC have not been described. Through comprehensive genomic profiling of 3,170 PDACs, we identified 5 cases (0.16%) that harbored an ALK fusion gene: an exon 6 EML4-exon 20 ALK translocation (n=3), an exon 13 EML4-exon 20 ALK translocation (n=1), and an exon 3 STRN-exon 20 ALK translocation (n=1). Among the most prevalent PDAC-related genes, activating KRAS mutations were absent in all 5 cases, who were
