Pancreatic cancer and autoimmune diseases: An association sustained by computational and epidemiological case-control approaches

Autoimmune pancreatitis (AIP) is considered a pancreatic manifestation of a newly proposed disease condition, IgG4-related disease (IgG4-RD). Recent epidemiological studies have addressed the incidence of cancer in patients with AIP and/or IgG4-RD with conflicting results. In this review, we discuss an association with cancer in patients with type 1 AIP and IgG4-RD.
