Current concepts on gastric carcinoid tumors.

摘要: Gastric carcinoid tumors (GCs) are rare lesions representing less than 10% of and 1% all stomach neoplasms. There three distinct types gastric carcinoids; type I includes the vast majority (70–85%) these neoplasms that closely linked to chronic atrophic gastritis. Type II which accounts for 5–10 %, is associated with Zollinger-Ellison syndrome often occurs in context multiple endocrine neoplasia 1. III, finally, represents 15–25% carcinoids characterized by a far more aggressive course. The optimal clinical approach GCs remains be elucidated, depending upon type, size, number carcinoids. While there universal agreement about surgical treatment III GCs, current options include simple surveillance, endoscopic polypectomy, excision or without antrectomy, total gastrectomy. Moreover, introduction somatostatin analogues could represent another therapeutic option.
