Liquid Biopsy (ctDNA) Guided Treatment in Localized Pancreatic Cancer: Neoadjuvant CTX vs. Upfront Surgery

This study evaluates the clinical prognostic impact (on DFS and OS) of liquid biopsy guided treatment vs. standard of care (physicians choice) in localized pancreatic cancer (despite because of CA 19-9 levels and computed tomography, upfront surgery is recommended by tumor board). ctDNA positive patients will receive neoadjvuant chemotherapy at current gold standard physicians choice instead of upfront surgery, because of assumed high biological risk for early recurrence.
