RESUMO
INTRODUCTION: Carcinoid tumors are the most common neuroendocrine tumors of the gastrointestinal tract. Surgical treatment and prognosis depend on the location of the tumor. METHOD: Between 01.01.1985 and 31.12.1999 25 patients with neuroendocrine tumors of the gastrointestinal tract or their metastases were treated in our institution. The records of these patients were reviewed retrospectively. Patients still alive were reexamined clinically. RESULTS AND CONCLUSIONS: The most frequent primary sites were the ileum and jejunum (36%), appendix (36%), stomach (12%), pancreas (8%), colon (4%) and bronchus with hepatic metastasis (4%). A malignant carcinoid syndrome was present in 8 patients. In patients with neuroendocrine tumors, curative, radical tumor removal should be attempted. Some patients with advanced disease needed some surgery for tumor debulking and resection of metastases. In non-resectable liver metastases hepatic arterial chemotherapy and chemoembolization after implantation of port catheters seem to be very beneficial therapeutic options. A fixed part of the therapeutic regime in progressive disease is adjuvant chemotherapy with 5-fluorouracil and streptozotocin and symptomatic therapy with octreotide.
