Application of MRD Combined With Personalized Vaccine in the Adjuvant Treatment of Postoperative Recurrence Prevention of Epithelial Ovarian Cancer
The goal of this clinical trial is as follows:(1) Establish a clinical technical system for ctDNA dynamic monitoring of MRD in postoperative EOC patients, providing a new technical means for postoperative recurrence prevention and monitoring of EOC patients.(2) Establish a clinical technical system for adjuvant treatment of postoperative recurrence prevention for EOC patients with conventional protocols combined with personalized vaccines, so as to provide a new treatment method for postoperative recurrence prevention for EOC patients, with a view to obtaining a better survival prognosis.(3) To establish and improve the prediction process of Neoantigen for ovarian cancer and the in vitro evaluation system of the effectiveness of neoantigen vaccine, achieve independent innovation of tumor neoantigen vaccine treatment technology, and cultivate a group of technical forces to master the development of modern tumor vaccine drugs.(4) The new technology system has been promoted and applied in 5 hospitals in the province.
