Endometrial cancer is the most common gynecological malignancy in developed countries. The management is primarily surgical, but adjuvant treatment may be indicated after surgery, according to the risk of recurrence. This review will focus on the prognostic risk groups presented in the 2020 ESGO/ESTRO/ESP guidelines and the ongoing trials based on new molecular markers that will help to get a more personalized cancer medicine.
