简要总结
This is a prospective cohort study aimed at clarifying the predictive value of MRD for postoperative DFS and OS in high-risk recurrent renal cell carcinoma patients who have undergone radical nephrectomy and received adjuvant treatment with Toripalimab. Further differentiating patients who need adjuvant immunotherapy.
详细描述
The study population is high-risk recurrent renal cell carcinoma patients who have undergone radical nephrectomy and meet the criteria of ECOG Score 0-1, no residual tumor on imaging. The study subjects will undergo MRD testing about 3 weeks after surgery, and the drug will be started within 4 weeks of surgery. Imaging (CT, MRI) will be performed from the first dose of Toripalimab, every 12 weeks, and DFS will be evaluated. Survival will be recorded every 3 months. The study aims to investigate the predictive value of MRD technology for DFS and OS in these patients after surgery and provide reference for distinguishing patients who need adjuvant immunotherapy.
