PG - 265-70 LID - 10.1159/000350309 [doi] AB - OBJECTIVE: The insulin-like growth factor (IGF) system has been known to play a critical role in tumor development and progression in many human cancers. However, the role of the IGF system in small intestinal carcinoma (SIC) has not been studied yet. METHODS: We evaluated the expression of IGF1 and IGF1 receptor (IFG1R) in a total of 194 cases of SIC. RESULTS: IGF1 expression was associated with well/moderate differentiation, better survival, lower pT, lower stage and no lymph node metastasis. IGF1R was more diffusely and strongly expressed in tumors with lower pT and lower stage. CONCLUSIONS: IGF1 and IGF1R expression is associated with favorable clinicopathologic parameters and may involve early carcinogenesis of SICs. Target therapy for the IGF1R signaling pathway may not have a major therapeutic role in treating SIC. CI - Copyright (c) 2013 S. Karger AG, Basel.
