Answer

For gastric tumors, the NCCN recommendations are as follows [7] :

  • With hypergastrinemia and tumors ≤2 cm: Endoscopic resection with biopsy or observation; or octreotide or lanreotide for patients with Zollinger-Ellison syndrome.

  • With hypergastrinemia and tumors >2 cm: Endoscopic resection, if possible, or surgical resection

  • With normal gastrin levels: Radical gastric resection and regional lymphadenectomy; endoscopic or wedge resection can be considered for tumors ≤2 cm
