Neoadjuvant and Adjuvant Therapy in Resectable Pancreatic Adenocarcinoma.

While pancreatic adenocarcinoma requires surgical resection definitive cure, treatment paradigms are shifting toward a neoadjuvant approach to systemic therapy. Rationale is twofold: micro-metastatic disease is likely present in a majority of patients, reinforcing the importance of systemic therapy regardless of resectability; moreover, systemic therapy is well-tolerated and improves surgical outcomes when delivered preoperatively. Second, a neoadjuvant approach allows for selection of biology and patients most likely to benefit from potentially morbid surgery. This review examines the increasing body of evidence in support of empiric neoadjuvant therapy in pancreatic adenocarcinoma.
