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). The gastrointestinal tract has different types of endocrine cells that vary from 1 site to another, depending of the functional needs of each region. Before [52] In the case of metastatic liver disease, surgery, somatostatin analogues, chemotherapy (streptozocin, 5-fluorouracil with leucovorin, cyclophosphamide, doxorubicin, oxaplatin, dacarbazine), and locoregional control methods (targeted radionucleotide therapies, transarterial chemoembolization, radiofrequency ablation) are recommended.

The background gastric mucosa shows moderate chronic gastritis with pseudopyloric and intestinal metaplasia. ECL cells are found diffusely throughout the glands in the body of the stomach. Autoimmune metaplastic atrophic gastritis (AMAG) is a chronic inflammatory disease characterized by immune-mediated replacement of gastric parietal cells with atrophic and metaplastic mucosa.1 Patients with AMAG often present with dyspepsia or symptomatic anemia; however, many remain asymptomatic in the early stages of the disease. [9], Gastric NENs were classified using the 2010 WHO classification of digestive NENs, which consists of a grading system, independently of the immunoprofile of the proliferating cells: grade 1 neuroendocrine tumors (G1 NETs), grade 2 neuroendocrine tumors (G2 NETs), G3 neuroendocrine carcinomas (NECs), and mixed adenoneuroendocrine carcinomas.
