Abstract
Small intestinal neuroendocrine tumors (SI-NET) are rare tumors, often with distant metastases at diagnosis. The objective of this review is to provide an overview of the latest literature regarding surgical management of the primary tumor in stage IV SI-NET. Primary tumor resection (PTR) seems to be associated with improved survival in patients with stage IV SI-NET, independent of treatment of distant metastases. A watch and wait approach of the primary tumor increases the risk of needing an emergency resection. PTR improves survival in patients with stage IV SI-NET, decreases the risk of emergency surgery, and should be considered in all patients with stage IV disease and unresectable liver metastasis.
