Biopsies of the gastric body showed hallmark features of AMAG, including antralization with loss of oxyntic glands and the full spectrum of disordered enterochromaffin-like (ECL) cell proliferation from hyperplasia to dysplasia to microneuroendocrine tumor (1 mm, MIB1 < 3%) (Figure 3C). 7.

Finally, we illustrate the suggested diagnostic process with 4 cases that are fairly representative of the type of situations encountered in everyday practice.

However, in another patient treated by antrectomy, postoperatively gastrin levels remained higher than normal, and NET recurrence was reported 5 years after the antrectomy. 1988 Apr;183(2):143-54. doi: 10.1016/S0344-0338(88)80042-6.

A prospective study of gastric carcinoids and enterochromaffin-like cell changes in multiple endocrine neoplasia type 1 and Zollinger-Ellison syndrome: identification of risk factors. The cells were positive for chromogranin A, synaptophysin, gastrin and cluster of differentiation 56 (Fig. [1] Epithelial dysplasia of the stomach with gastric immunophenotype shows features of biological aggressiveness. Netazepide, a gastrin/cholecystokinin-2 receptor antagonist, can eradicate gastric neuroendocrine tumours in patients with autoimmune chronic atrophic gastritis. Surgical treatment is recommended for patients with type 2 g-NETs, primarily directed to underlying disease (removal of gastrinomas, in order to reduce the ECL cells stimulation).

Epithelial dysplasia of the stomach with gastric immunophenotype shows features of biological aggressiveness. The patient did not consent for surgical treatment of the tumor, and oncologic therapy was indicated. Immunohistochemical staining for CDX-2, PDX-1, NESP-55, and TTF-1 can help distinguish gastrointestinal carcinoid tumors from pancreatic endocrine and pulmonary carcinoid tumors.

Given the oncogenic potential of ECL cells changes, a regular endoscopic and histological follow-up of the patient is advisable when ECL cells hyperplastic and dysplastic proliferations are detected in gastric biopsy specimens. During Caduet drug therapy, a variety of unwanted effects may arise, among which the most common is peripheral edema. [33], The patient with antral tumor and liver metastases (case 3) declined surgical treatment and chose the medical therapy. The pancreatic tumor was a well-differentiated NET, with uniform cells, without nuclear pleomorphism, with Ki-67 proliferative index <2%, and 1 mitosis/10 HPF. Lyon: IARC Press; 2010. In the stomach, endocrine cells have an essential role in acid secretion. Careers. 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.
