Clinic, Pathologic and Genetic Characterization of Patients With Familial Carcinoid Tumors (Study From the GTE, Groupe d'étude Des Tumeurs Endocrines)

August 17, 2018 updated by: CHU de Reims

Small intestine carcinoid tumors are rare. Small intestine Familial Carcinoid Tumors (FCT) are defined by the occurrence of at least 2 cases of this tumor type in first- or second-degree relatives. The estimated prevalence of FCT is 2.6%-3.7% in patients with small intestine carcinoid tumors. Because of its rarity, epidemiologic, clinic and pathologic features of FCT have been scarcely described. Molecular abnormalities associated with FCT have been poorly explored. Constitutional genetic factors predisposing to FCT have not been discovered to date. Only one abnormality (mutation of the IPMK gene) has been reported in one FCT family only, but not found in other series.

The main objective of this study is to identify the constitutional factors predisposing to small-intestine FCT (and other midgut localizations: ascending colon and appendix). The secondary objectives are to describe the clinic and pathologic features associated with FCT.
