Clinical Reviews of Patients with Carcinoid Tumor
Abstract
-
BACKGROUND AND AIMS: The term, carcinoid, is derived from Karznoid"" coined by Oherndorfer in 1907, which means carcinoma like lesion with no malignant potential. However, it is now generally accepted that these innocuous neoplasms potentially can produce widespread metastasis. Although the carcinoid tumor is relatievely rare, it continue to be of special clinical interest because of the endocrine potential, the malignant potential and the recent appearance of the composite carcinoma-carcinoid tumor.
METHODS
We reviewed the recorded clinical rnanifestations of twenty-two patients with carcinoid tumor, which had been treated from the Kang Book Samsung Hospital for l7 years frorn August 1979 to Septernher 1996.
RESULTS
The peak incidence was in the 5th decade occupying 9 cases (42%) and male predominence with a ratio of 2.1:1. The common site of the tumors was the rectum (8 cases) and appendix (5 cases). The incidence ot' carcinoid tumors according to the embryologic origin were foregut 6 cases (27%), midgut 7 cases (321o), hindgut 9 cases (41%). The hepatic metatasis was presented in 3 cases. There was no case with classic carcinoid syndrome. Thirty-two percent cases had carcinoma with carcinoid tumor, and nine percent cases had malignant carcinoid tumor.
CONCLUSIONS
Comparing the age and tumor location, some difference was observed between 22 cases carcinoid tumor experienced at our hospital and those of foreign studies, but other difference was not observed.
