Study of PD-1 Antibody and Bevacizumab in the Treatment of High-risk GTN After Combined Chemotherapy

Summary

Gestational trophoblastic Neoplasia（GTN） is a kind of malignant tumor in women of childbearing age. It is easy to metastasized through the blood system in the early stage, so it is a relatively malignant tumor. The tumor is highly sensitive to chemotherapy, and low-risk patients have good prognosis, with survival rate and cure rate approaching 100%, but high-risk patients are prone to drug resistance, or relapse after remission. For relapsed, refractory, high-risk GTN, multiple remedies have been reported in the literature, but the remission rate is only 75-80%. For relapsed or refractory high-risk GTN, multiple remedies have been reported in the literature, but the remission rate is only 75-80%. Currently, targeted therapy and immunotherapy are widely used in various refractory solid tumors. For GTN, there are also a number of related studies. In this study, PD-1 inhibitors combined with bevacizumab were used to treat refractory high-risk GTN with relapse or drug resistance after receiving previous second-line or above multidrug combination therapy, to study the efficacy and safety of the treatment regimen.
