Study of SHR-1210 Combined With Apatinib in the Treatment of Sarcoma

To observe the effectiveness of SHR-1210 (Camrelizumab) combined with apatinib in the treatment of unresectable sarcoma patients with chemotherapy failure. The main observations were progression-free survival (PFS) and progression-free control rate (PFR), followed by objective response rate (ORR) (CR+PR), disease control rate (DCR) (CR+PR+SD), and overall survival (OS).

To observe the safety of SHR-1210 (Camrelizumab) combined with apatinib in the treatment of sarcoma
