Some authors advocate antrectomy in order to eliminate the gastrin stimulus that promotes tumor growth, and local resection of the largest tumors with subsequent endoscopic surveillance of the gastric remnant.[15,41,42] Vanoli et al reported in 1 patient with type A-CAG and type I gastric NET treated by antrectomy a decrease in gastrin levels to undetectable levels, and a regression of ECL cell hyperplasia postoperatively, without NET recurrence. Here, GAST is linked to gastric neuroendocrine tumor, well differentiated, low or intermediate grade.
