Survival after Resection for Invasive Intraductal Papillary Mucinous Neoplasm and for Pancreatic Adenocarcinoma: A Multi-Institutional Comparison According to American Joint Committee on Cancer Stage

Abstract

When matched by stage, inv-IPMN has superior survival after resection compared with PDAC. This disparity is greatest in node-negative and least in node-positive disease. These findings suggest the behaviors of inv-IPMN and PDAC, although different, converge with advancing American Joint Committee on Cancer stage because of a greater proportion of tubular subtype.
