Recent studies have suggested that local destruction of tumor tissue by cryoablation induced activation and maturation of dendritic cells and tumor-specific T cells by cross-presentation of tumor antigens. While pd-1 blocking antibody interferes with PD-1 mediated T-cell regulatory signaling. And combination of pd-1 blocking antibody plus lenvatinib showed increased ORR in many type of human cancers, including advanced intrahepatic cholangiocarcinoma. Therefore, the objective of this study is to evaluate the efficacy and safety of cryoablation combined with Sintilimab plus lenvatinib in patients with advanced intrahepatic cholangiocarcinoma.
The objective of this study is to evaluate the efficacy and safety of cryoablation combined with Sintilimab plus lenvatinib in patients with advanced intrahepatic Cholangiocarcinoma after progression on first line systemic therapy.
