<jats:sec> <jats:title>Objectives:</jats:title> <jats:p>To describe the survival outcome of patients with borderline resectable or locally advanced pancreatic ductal adenocarcinoma (BR/LA-PDAC) who have a pathologic complete response (pCR) following neoadjuvant chemoradiation.</jats:p> </jats:sec> <jats:sec> <jats:title>Background:</jats:title> <jats:p>Patients with BR/LA-PDAC are often treated with neoadjuvant chemoradiation in an attempt to downstage the tumor. Uncommonly, a pCR may result.</jats:p> </jats:sec> <jats:sec> <jats:title>Methods:</jats:title> <jats:p>A retrospective review of a prospectively maintained database was performed at a single institution. pCR was defined as no viable tumor identified in the pancreas or lymph nodes by pathology. A near complete response (nCR) was defined as a primary tumor less than 1 cm, without nodal metastasis. Overall survival (OS) and disease-free survival (DFS) were reported.</jats:p> </jats:sec> <jats:sec> <jats:title>Results:</jats:title> <jats:p>One hundred eighty-six patients with BR/LA-PDAC underwent neoadjuvant chemoradiation and subsequent pancreatectomy. Nineteen patients (10%) had a pCR, 29 (16%) had an nCR, and the remaining 138 (74%) had a limited response. Median DFS was 26 months in patients with pCR, which was superior to nCR (12 months, <jats:italic toggle="yes">P</jats:italic> = 0.019) and limited response (12 months, <jats:italic toggle="yes">P</jats:italic> < 0.001). The median OS of nCR (27 months, <jats:italic toggle="yes">P</jats:italic> = 0.003) or limited response (26 months, <jats:italic toggle="yes">P</jats:italic> = 0.001) was less than that of pCR (more than 60 months). In multivariable analyses pCR was an independent prognostic factor for DFS (HR = 0.45; 0.22–0.93, <jats:italic toggle="yes">P</jats:italic> = 0.030) and OS (HR=0.41; 0.17–0.97, <jats:italic toggle="yes">P</jats:italic> = 0.044). Neoadjuvant FOLFIRINOX (HR=0.47; 0.26–0.87, <jats:italic toggle="yes">P</jats:italic> = 0.015) and negative lymph node status (HR=0.57; 0.36–0.90, <jats:italic toggle="yes">P</jats:italic> = 0.018) were also associated with improved survival.</jats:p> </jats:sec> <jats:sec> <jats:title>Conclusions:</jats:title> <jats:p>Patients with BR/LA-PDAC who had a pCR after neoadjuvant chemoradiation had a significantly prolonged survival compared with those who had nCR or a limited response.</jats:p> </jats:sec>
