[Our experience regarding biologically inactive gastroenteropancreatic neuroendocrine tumors]

The Authors present 9 cases of gastro-enteropancreatic neuro-endocrine biologically inactive tumors. In 5 cases the tumor site was appendicular. In 4 patients an appendectomy was performed, in one patient a right hemicolectomy and the patients after a period of 3-9 years are well and disease free. In a patient with a gastric carcinoid and a single hepatic metastasis a total gastrectomy with an hepatic metastasectomy were performed but the patient died 16 months thereafter. In a case localized to the right colon with a single hepatic metastasis a right hemicolectomy was performed with a metastasectomy but the patient died after 12 months. In a case localized to an ileal loop a segmental resection was performed followed by a medical therapy with octreotide and the patient is well and disease free after 3 years. In a case localized to the pancreas with widespread lymphatic metastasis it was performed a simple biliary diversion (coledocho-duodenostomy) followed by medical therapy with octreotide. Surprisingly after 4 years the patient is alive and a TC control shows a decrease of the pancreatic tumor and of the lympho glandular tumefactions.
