BACKGROUND: Multiple neoadjuvant therapy protocols have been proposed in the treatment of pancreatic adenocarcinoma, including chemotherapy (CT), chemoradiation (CRT), and total neoadjuvant therapy (TNT), defined as a CT plus CRT. A pathologic complete response (pCR) can be achieved in a minority of cases. We hypothesize that TNT is more likely to confer pCR than other neoadjuvant therapies, which may improve overall survival (OS). METHODS: A retrospective review of the National Cancer Database (NCDB) from 2006-2016 was performed, identifying patients who underwent any neoadjuvant therapy followed by definitive pancreatic resection for locally advanced or borderline resectable pancreatic adenocarcinoma. A pathologic complete response was defined as down-staging from any clinical stage to pathologic stage 0. RESULTS: A total of 5,402 patients who received neoadjuvant therapy followed by resection were identified. 177 patients (3.3%) achieved a pCR. Of the patients who achieved a pCR, 57 received CT, 41 CRT and 79 received TNT. On multivariate analysis, TNT was more likely to confer a pCR than CRT (OR 1.67, CI 1.13-2.46, p=0.0103) or CT (OR 2.61, CI 1.83-3.71, p
