Overview
Efficacy and Safety of Locoregional treatments Combined With PD-1 Inhibitor in Patients With Unresectable Hepatocellular Carcinoma.
Description
Hepatocellular carcinoma is the most frequent primary and ranked as the sixth most common neoplasm and the third leading cause of cancer death.
Percutaneous ablation and TACE are the effective locoregional treatments for the patient with HCC. Moreover, some studies suggested that TACE combined with ablation could further improve the survival rate and reduce the post-operation complication.
Although PD-1 inhibitor was approved by FDA for HCC, the latest RCT indicated that no significant difference was found in the ORR and PFS between the groups of PD-1 inhibitor and Sorafenib.
Therefore, this study aims to assess the efficacy and safety of microwave ablation combined with simultaneous TACE plus PD-1 inhibitor for the non-resectable HCC.
