Autoimmune pancreatitis, pancreatic and extrapancreatic cancer (AIPPEAR): a multicentre, retrospective study protocol.

ABSTRACT:

Introduction

Autoimmune pancreatitis (AIP) mainly manifests in two distinct forms with different clinical, serological and prognostic characteristics. Previous studies indicated a higher risk of malignancy in AIP patients compared with the general population. However, a direct comparison of cancer incidence in AIP patients with controls from the general population has not been conducted yet.

Methods and analysis

This is an international, multicentre, retrospective study on patients diagnosed with AIP after 2005. Retrospective data regarding demography, AIP characteristics and cancer incidence will be extracted from the medical files of AIP patients. The primary outcome is the standardised incidence ratio of any first invasive cancer after AIP diagnosis compared with the gene
