Bachmann et al. examined EZH2 protein expression levels in a series of 316 endometrial tumor samples and found that higher EZH2 expression correlated with the aggressive serous papillary and clear cell carcinoma subtypes, high histologic and nuclear grade, and advanced clinical FIGO stage (International Federation of Gynecology and Obstetrics, explanation of FIGO staging in Explanation of staging and statistical terms section) [6]. Here, EZH2 is linked to clear cell adenocarcinoma.
