The goal of this observational study is to develop an exosome-based scoring model for post-treatment surveillance of recurrence in ovarian cancer. The main questions it aims to answer are:
1. Does this model have the potential for ovarian cancer recurrence monitoring?
2. Can this model demonstrate superior performance to CA125 for ovarian cancer recurrence monitoring?
Participants will :
1. Provide serial blood samples at predefined times
2. Undergo standardized imaging and clinical assessments during follow-up visits
