The data of patients whose treatment with gynecologic malignancies was initiated in 2023 were analyzed retrospectively.

This clinicopathological information was summarized as the Patient Annual Report. The 5\u2010year survival rates of the patients who initiated treatment in 2018 were as follows. For cervical cancer, the rates were 92.6%, 75.7%, 57.3%, and 25.9% for Stages I, II, III, and IV, respectively. For endometrial cancer, the rates were 94.3%, 88.3%, 75.2%, and 32.1% for Stages I, II, III, and IV, respectively.
