This study investigated the clinicopathological significance of estrogen receptor 1 (ESR1) gene amplification and its relationship to phosphatase and tensin homolog (PTEN), human epidermal growth factor receptor 2 (HER2), MutL homolog 1 (MLH1), p53, and AT rich interactive domain 1A (ARID1A) expression in endometrial carcinomas. ESR1 amplification and expression were assessed by fluorescence in situ hybridization and immunohistochemistry. Clinical data were collected by retrospective chart review. ESR1 amplification was identified in 13 out of 111 (11.7%) endometrial carcinomas. No significant association was observed between ESR1 amplification and International Federation of Gynecology and Obstetrics (FIGO) stage (p=0.17), histological grade (p=0.35), lymph node metastasis (p=0.51), or deep myometrial invasion (p=0.46). ESR1 amplification was independent of PTEN, p53, HER2, MLH1, and ARID1A protein expression. Patients without estrogen receptor (ER) or progesterone receptor (PR) expression had shorter progression-free and overall survival than those with ER or PR expression (p<0.01). ESR1 amplification is independent of known clinicopathological factors related to poor prognosis and PTEN, p53, HER2, MLH1, and ARID1A protein expression, suggesting ESR1 amplification may be an early event in endometrial carcinoma development.
