Specific survival nomograms based on SEER database for small intestine adenocarcinoma

Background: Small intestine cancers, as an extremely rare tumor type, account only for 3% of all gastrointestinal tumors. adenocarcinoma (SIA), representing approximately one-third small bowel has received relatively little attention, both in research efforts and clinical cognizance. Owing to anatomical proximity rarity, adenocarcinomas are frequently grouped with colorectal adenocarcinomas. Therefore, a large SIA patient cohort is needed develop validate new nomogram prognostic models specific patients.
