SMALL BOWEL NEOPLASM CHARACTERIZATION AND INFLAMMATORY-RELATED AND SPORADIC SMALL BOWEL ADENOCARCINOMA COMPARISON OF CLINICAL FEATURES

Small bowel cancer (SBC) represents 1 to 5 % of all gastrointestinal cancer and is a rare cancer with a bad prognosis often arising in a Crohn's disease context. Histopathologic types of small bowel cancer comprehend adenocarcinomas, gastrointestinal stromal tumors (GISTs), neuroendocrine tumors (NET), and lymphoma. This study first aims to assess if there are prognostic and clinical criteria to distinguish between adenocarcinoma, Net and Gist to create a possible algorithm for the diagnostic exams in patients with undefined small bowel neoplasm. This study second aims to assess the burden of small bowel cancer (SBC) in patients with Crohn's disease (CD) and in those without IBD, and to identify possible factors associated with morbidity and with a poor prognosis.
