Ovarian clear cell carcinoma (OCCC) is one of the rare subtypes of ovarian cancer, yet its prognosis is extremely poor. Previous studies indicates that both bevacizumab and PD-1 inhibitor have clinical benefit for OCCC patients. And the combination of bevacizumab and PD-1 inhibitor has shown preliminary safety and clinical activity. Therefore, this study aims to investigate the protential benefit of combation therapy for patients with OCCC.
