    Abstract:
    Twenty-one patients with carcinoid tumors have been analysed. Out of 18 patients the diagnostic was made at operation and out of 3 by autopsy. The most frequent sites of the primary tumors were the appendix (38.1%), ileum (23.8%) and colon (19.9%). Asymptomatic tumors were found incidentally in 10 patients (55.5%). The symptomatic neoplasms were more common in the ileum. No one patients in this series obtained the diagnostic of carcinoid tumors before operation or autopsy. It was not observed the malignant carcinoid syndrome. Sixteen patients (88.8%) were submitted to resection and the mean survival was 10.7 years. Two patients (11.1%) were submitted to palliative operations and the mean survival was 3.5 months. The incidence of metastases in cases with carcinoid greater than 2.0 cm in diameter was 71.4%; on the other hand, the patients with carcinoids 2.0 cm in diameter or smaller than this size disclosed metastases in 7.6%. No patients with appendix carcinoid showed metastases and all patients with metastases presented ileum or colon carcinoids. In this series, the prognostic was related with the lesion's size, the localization of the tumor in the gastrointestinal tract and with the resection or not of the primary neoplasm.
