First-line treatments
GI disease management
Treatment options should be discussed with a qualified healthcare provider.
Surgical resection
Complete surgical removal of the primary tumor in the ileum, which is often the first-line curative approach for localized disease. May include regional lymph node dissection.
Somatostatin analog therapy
Long-acting somatostatin analogs administered to control hormone-related symptoms and potentially slow tumor progression in both localized and metastatic disease.
Additional treatment options
Surveillance imaging and biomarkers
Regular monitoring with imaging studies and tumor markers to detect recurrence or assess treatment response. Follow-up schedules are individualized based on disease stage.
monitoringLiver-directed therapy
Targeted therapies such as hepatic artery embolization or radiofrequency ablation for liver metastases to control tumor burden and symptoms.
procedureSpecialized nutritional support
Dietary modifications to manage symptoms such as carcinoid syndrome, including recommendations for small frequent meals and trigger avoidance.
