Relationship of Time to First Therapy and Survival Outcomes of Neoadjuvant Chemotherapy Versus Upfront Surgery Approach in Resectable Pancreatic Ductal Adenocarcinoma.

Introduction: Evidence demonstrating overall survival benefit of neoadjuvant chemotherapy (NAC) followed by surgical resection over upfront surgical resection for resectable pancreatic ductal adenocarcinoma (PDAC) has been mixed. The time to first therapy (TTFT) variable has not been studied as a contributing factor.

Methods: A nationwide retrospective analysis using the National Cancer Database to evaluate patients with clinical stage T1 and T2 PDACs from 2010 to 2020.
