Impact Of Nab-Paclitaxel-Based Second-Line Chemotherapy On The Outcomes Of Pancreatic Cancer.

483Background: Pancreatic ductal adenocarcinoma (PDAC) is a lethal malignancy with no standard second line chemotherapies. We conducted a retrospective study with the primary aim to examine the effect of second line chemotherapy with nab-paclitaxel-based regimen on the overall survival (OS) and progression-free survival (PFS) of locally advanced and metastatic PDAC patients. Methods: Indiana University Simon Cancer Center (IUSCC) Cancer Registry was used to identify patients with locally advanced or metastatic PDAC between 2009 and 2015. Only patients who received second line chemotherapies were included in the study. These patients were divided in to two groups: a) nab-paclitaxel-based treatment and, b) non-nab-paclitaxel-based treatment. Demographic (age, race, gender, year of diagnosis, family history, comorbidity), clinical (histology, CA 19-9, bilirubin, tumor location, performance status, metastatic sites, chemotherapy, surgery or radiation) and outcome (OS, PFS) characteristics were obtained.
