Core Tip: Endometrial cancer is the most common gynecological cancer in developed countries, and its incidence has increased. A significant proportion of endometrial cancer, which mainly comprises high-grade or type II endometrial cancer, including serous carcinoma and carcinosarcoma, shows a dismal prognosis. Recent molecular analyses revealed human epidermal growth factor receptor 2 (HER2) overexpression/ gene amplification in 20%-40% of patients with type II endometrial cancer. Notably, HER2 targeted therapy for type II endometrial cancer has been dramatically developed. We review the recent findings on endometrial cancer, current treatment, optimized HER2 testing, key clinical trials on HER2 targeted therapy, and future directions in these aggressive endometrial cancers.
