The study herein successfully developed a new immunotherapeutic approach combined with radiotherapy, and tried to proved it to be more effective and safe.

Hepatocellular carcinoma (HCC) is the fifth most common cancer and the third leading cause of cancer-related death worldwide. The resection rate for HCC is approximately 10%-30% and the overall prognosis is very poor with a 5-year survival rate of 5%-6%. The recurrence rate is high after radical resection. In addition to surgery, radiofrequency ablation, transcatheter arterial chemoembolization (TACE), microwave ablation, cryoablation, radioactive seeds implantation, high-intensity-focused ultrasound, radiation therapy, chemotherapy and targeted drugs are available for patients with unresectable tumors; however, the efficacy of these treatments are limited and long-term prognosis in the patients is still poor. Moreover, due to serious side effects induced by treatments such as TACE, chemotherapy and targeted drugs, it may not be possible for patients to continue receiving these therapies. The study herein successfully developed a new immunotherapeutic approach combined with radiotherapy, and tried to proved it to be more effective and safe.
