Compared to IPMN alone, E6 levels Clinical Signifi cance of Serum COL6A3 Isoforms in were signifi cantly higher in PDA (p = 0.0036). There were Pancreatic Ductal Adenocarcinoma no signifi cant differences between E6 levels in IPMN and Christopher Y. Kang, Dierdre Axell-House, Pranay Soni, Normal sera (p = 0.59). Using a logistic regression model, Galina Chipitsyna, Konrad Sarosiek, Mazhar Al-Zoubi, Hwyda A. we found that for each increasing unit of log E6 COL6A3, Arafat, Charles J. Yeo patients are 9.5 times more likely to harbor a cancer rather Surgery, Thomas Jefferson University, Philadelphia, PA than a benign lesion, 95% CI (2.4, 38.1), p = 0.002.

Knocking down E3 INTRODUCTION: Type VI collagen (COL6) forms a or E4 or E6 with isoform-specifi c siRNA resulted in reduced microfi brillar network associated with type I collagen fi brils PDA cell migration and invasion and concomitant reduc- and constitutes a major component of the prominent des- tion of the expression of several infl ammation and angio- moplastic reaction in pancreatic ductal adenocarcinoma genesis-related genes, such as MMP-9, OPN, MCP-1 and (PDA). We have demonstrated recently that a subunit of VEGF. Interestingly, knocking down any of the 3 isoforms COL6, COL6A3, is expressed in high levels in PDA tissue. resulted in increased expression of TNF-alpha. We also showed that COL6A3 gene undergoes tumor-spe- cifi c alternative splicing to produce 3 isoforms E3, E4 and CONCLUSIONS: Our data show for the fi rst time the E6 that are tumor tissue-specifi c. The aim of this study is to potential clinical signifi cance of circulating E6 COL6A3 lev- investigate the diagnostic value and clinical signifi cance of els in the diagnosis of pancreatic malignancy. Our in vitro circulating COL6A3 isoforms mRNA in PDA. data suggests a role for COL6A3 isoforms in PDA progres- sion and metastatic potential. METHODS: Serum samples were obtained from patients that underwent pancreatic resection at a single institution between 2006 and 2009. COL6A3 levels in the sera from 200 patients with pathologically confi rmed PDA (n = = 40), Treatment Sequencing for Resectable Pancreatic intraductal papillary mucinous neoplasms (IPMN) (n = 20), Cancer: Infl uence of Early Metastases and Surgical and chronic pancreatitis (n = 10) were analyzed by real time Complications on Multimodality Therapy Completion PCR using isoform-specifi c primers for E3, E4 and E6.
