Abstract
Pancreatic ductal adenocarcinoma (PDAC) is a lethal disease with a dismal prognosis; this is in part due to its late diagnosis at advanced stages. For many patients, medical treatment is the only practicable therapy. In recent years, the development of new technologies that investigate genomic biomarkers has improved the concept of precision medicine to treat patients with PDAC. Through endoscopic ultrasound-tissue acquisition (EUS-TA), tissue from pancreatic cancers can be collected; thus, it has the potential to advance personalized treatment by allowing the assessment of genomic alterations. In this review, we explore the role of EUS in genomic profiling and its strengths and pitfalls in obtaining samples for next-generation sequencing (NGS).
