title: [Carcinoid tumors and neuroendocrine carcinomas of the stomach. Prognosis and therapeutic management. Study of 6 cases].
abstract: The six reported cases were separated into 2 groups: 1) the tumors of sporadic type, carcinoids (n = 2) and neuro-endocrine carcinomas (n = 2); 2) the gastrin-promoted tumors (n = 2). The purpose of this retrospective study was to review for each group of tumors, the clinicopathologic characteristics, prognosis factors and optimal management. In the first group, patients with a small and well differentiated tumor revealed by digestive bleeding, were treated by wedge excision and are alive and well 24 and 22 years later; the patients with large, invasive and poorly differentiated tumors were treated by subtotal (n = 1) and total (n = 1) gastrectomy, and died 1 year and 3 years later with metastases. In the second group, one patient with a small asymptomatic carcinoid tumor revealing chronic atrophic gastritis, was treated by endoscopic resection, without recurrence 3 years later; another patient with asymptomatic multifocal carcinoid tumors (about 100) associated with Zollinger-Ellison syndrome and multiple endocrine neoplasia type 1, was treated by total gastrectomy and is alive and well 7 years later. No patient had carcinoid syndrome. Synaptophysin was the most sensitive marker and secretion of serotonine was detected in 2 tumors.
  
  
  CONCLUSIONS
  Sporadic carcinoids serotonin and neuro-endocrine carcinomas are life-threatening tumors and need aggressive surgical therapy: their prognosis depends on tumors size, histological differentiation and mostly on tumor extension. In contrast, gastrin-promoted carcinoids do not result in disseminated disease and death, and a rather conservative approach seems appropriate.
