Clinicopathological Stratification and Long-term Follow-up of Patients with Periampullary Carcinomas.

Background: Periampullary carcinomas generally confer a poor outcome. Choosing the most effective treatment regimen for each sub-entity proves challenging and is usually based on experience from pancreatic adenocarcinoma (PDAC).

Patients And Methods: The long-term follow-up is presented of 472 patients with periampullary tumors [PDAC, distal cholangiocarcinoma (dCC) and ampullary carcinomas (AC)] who underwent radical resection considering clinical characteristics, paraclinical findings and histopathological features in order to define factors of prognostic relevance.
