CCNE1 amplification is associated with aggressive potential in endometrioid endometrial carcinomas.

CCNE1 amplification is associated with aggressive potential in endometrioid endometrial carcinomas. Int J Oncol. 2015 Nov 26; Authors: Nakayama K, Rahman MT, Rahman M, Nakamura K, Ishikawa M, Katagiri H, Sato E, Ishibashi T, Iida K, Ishikawa N, Kyo S Abstract The clinicopathological significance of amplification was investigated of the gene encoding cyclin E (CCNE1) and we assessed whether CCNE1 was a potential target in endometrioid endometrial carcinomas. CCNE1 amplification and CCNE1 or F-box and WD repeat domain-containing 7 (FBXW7) expression in endometrial endometrioid carcinoma was assessed by immunohistochemistry and fluorescence in situ hybridization. CCNE1 knockdown by small interfering RNA (siRNA) was used to assess the CCNE1 function. The results showed that CCNE1 amplification was present in 9 (8.3%) of 108 endometrial carcinomas. CCNE1 amplification was correlated with high histological grade (Grade 3; p=0.0087) and lymphovascular space invasion (p=0.0258). No significant association was observed between CCNE1 amplification and FIGO stage (p=0.851), lymph node metastasis (p=0.078), body mass index (p=0.265), deep myometrial invasion (p=0.256), menopausal status (p=0.289) or patient age (p=0.0817). CCNE1 amplification was significantly correlated with shorter progression-free and overall survival (p=0.0081 and 0.0073, respectively). CCNE1 protein expression or loss of FBXW7 expression in endometrial endometrioid carcino...
