Small intestine cancers are uncommon but disproportionately delayed in diagnosis because their symptoms often resemble benign gastrointestinal disease and routine upper endoscopy and colonoscopy leave much of the small bowel unevaluated. From the AAVBC's perspective, value-based care begins with accountable diagnostic stewardship rather than repeated reassurance or empiric treatment. Persistent unexplained iron-deficiency anemia, occult gastrointestinal bleeding, abdominal pain, weight loss, or obstructive symptoms after negative conventional endoscopy should prompt dedicated small bowel evaluation with CT or MR enterography, capsule endoscopy, or specialist referral. The highest-value intervention is shortening the months-to-years diagnostic delay that commonly allows potentially treatable disease to present at an advanced stage.
Drawing from current NCCN Small Bowel Adenocarcinoma, NCCN Neuroendocrine and Gastrointestinal Stromal Tumor, and ENETS guidance, AAVBC's Small Intestine Cancer Quick Reference Guide focuses on the clinical decisions where primary care creates the greatest value. It highlights histology-specific ICD-10 coding, anatomic subsite documentation, MEAT standards, recognition of subtype-specific presentations, mandatory MMR/MSI testing for newly diagnosed small bowel adenocarcinoma, and coordinated nutritional pre-habilitation. The guide also emphasizes geriatric-informed shared care, recognizing that functional reserve—not chronological age alone—should guide treatment intensity while proactive symptom monitoring and nutrition support help reduce avoidable emergency visits and hospitalizations.
AAVBC’s Deep-Dive series offers a comprehensive, structured analysis of small intestine cancer — moving far beyond quick-reference essentials. These guides provide an integrated review of epidemiology, diagnostic strategy, staging, coding logic, MEAT-aligned documentation examples, treatment guidelines, review vulnerabilities, and cost-utilization considerations. The Deep-Dive combines evidence-informed clinical guidance with practical operational tools to support a deeper understanding of disease complexity and provide multidisciplinary teams with strategies to thrive within value-based frameworks.
