Risk and survival outcomes of secondary pelvic neoplasm after radiotherapy in female patients with genital neoplasms: A large Population-Based cohort study.

Background And Purpose: To investigate the impact of radiotherapy (RT) on the risk of secondary pelvic neoplasms (SPN) and the survival outcomes of patients following a diagnosis of female patients with genital neoplasm(FGN).

Materials And Methods: Utilizing SEER databases, this study involved 102,895 patients from nine oncology centers, spanning 1990 to 2015. We employed the Fine-Gray competing risks regression methodology to chart the trajectory of SPN development and used the Kaplan-Meier method to calculate the 10-year overall survival rates.
