Gastric Type I Neuroendocrine Tumors Endoscopic Treatment Options

#1519

Introduction: From 1998 till 2014 in our institution we have identified 72 patients with type I gastric neuroendocrine tumors (NET), 42 of them, without regional or distant metastases, undergone different types of endoscopic treatment.

Aim(s): In patients (21) with type I flat G1 lesions 0,5 cm and smaller, located within mucosa, we have used argon-plasma coagulation (APC). Mean tumor amount, destructed with APC was 14, mean size – 0,4 cm. We have not observed any tumor recurrence at treatment sites, but in 28,5% patients new G1 NETs were developed within 1 year after treatment in different mucosal areas.

Materials and methods: Mean amount of de novo tumors was 4,4, mean size – 0,2 cm. In all cases second phase APC was implemented. Patients (18) with gastric type 1 G1 NETs sized 0,5 – 1 cm undergone endoscopic mucosal resection (EMR). In 72,2% of them we have diagnosed simultaneously small (less than 0,5 cm) and bigger (0,5 – 1 cm) tumors, so EMR was performed in parallel with APC.
