Neoadjuvant of Axitinib Plus PD-1 to Improve Disease Free Survival of Patients With Renal Cell Carcinoma

A Multicenter Randomized Controlled Clinical Study of Neoadjuvant Combination of Axitinib Plus PD-1 Monoclonal Antibody to Improve Disease Free Survival of Patients With Renal Cell Carcinoma

The study included 298 RCC patients who were at high risk for recurrence after nephrectomy (T2G3-4 or T3-4 or N1). They were randomly divided to receive axitinib plus PD-1 + surgery or surgery alone at a ratio of 1:1, so as to determine the efficacy of the neoadjuvant combination of axitinib plus PD-1.

Given the good results of TKI plus PD-1 in our previous cases and its good effect on advanced RCC, we plan to eliminate tumor micrometastases and improve anti-tumor immunity with the neoadjuvant combination of axitinib plus PD-1, so as to improve patient outcomes. The study included 298 RCC patients who were at high risk for recurrence after nephrectomy (T2G3-4 or T3-4 or N1). They were randomly divided to receive axitinib plus PD-1 + surgery or surgery alone at a ratio of 1:1, so as to determine the efficacy of the neoadjuvant combination of axitinib plus PD-1 and provide evidence-based medical evidence for clinical perioperative treatment of these patients.
