Abstract

PURPOSE: EZH2 is a member of the polycomb group of genes and important in cell cycle regulation. Increased expression of EZH2 has been associated previously with invasive growth and aggressive clinical behavior in prostate and breast cancer, but the relationship with tumor cell proliferation has not been examined in human tumors. The purpose of this study was to validate previous findings in a population-based setting, also including tumors that have not been studied previously. PATIENTS AND METHODS: In our study of nearly 700 patients, we examined EZH2 expression and its association with tumor cell proliferation and other tumor markers, clinical features, and prognosis in cutaneous melanoma and cancers of the…
