OVARIAN CANCER, CANCER
Ovarian cancer (OC) is one of the most lethal gynecological malignancies among women worldwide, with 81,584 new cases and 54,220 deaths in 2022 [Nomogram is a widely used tool, which is shown as a comprehensive and readable model to predict the prognosis of patients diagnosed with cancer [In this article, based on publicly available data from the Surveillance, Epidemiology, and End Results (SEER) database, we established and validated nomograms of overall survival (OS) and cancer-specific survival (CSS) in elderly EOC cases based on significant prognostic factors. Additionally, the C-statistic, calibration diagrams, and DCA curves were used to evaluate the discrimination and clinic utility of the nomograms. This study aimed to provide personalized survival predictions and optimize the clinical management of elderly EOC patients.
