Clinical Trial Summary

To explore the efficacy and safety of toripalimab plus stereotactic body radiotherapy for hepatocellular carcinom with portal vein tumor thrombus.

Description:

Programmed Cell Death Protein-1 (PD-1) was effective and tolerable in patients with advanced hepatocellular carcinoma. Additionally, previous studies showed that stereotactic body radiotherapy (SBRT) was effective for hepatocellular carcinoma with portal vein tumor thrombus (PVTT). No study has evaluated the efficacy and safety of toripalimab plus SBRT for hepatocellular carcinoma with PVTT. Thus, the investigators carried out this prospective study to find out it.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Progression free survival (PFS)	PFS was defined as the time from the date of randomization to the date of first documentation of disease progression based on iRECIST, or date of death, whichever occurred first	6 months
Secondary	Overall survival (OS)	OS was defined as the duration from the date of randomization until the date of death from any cause. Participants who were lost to follow-up were censored at the last date the participant was known to be alive, and participants who remained alive were censored at the time of data cutoff.	6 months
Secondary	Objective Response Rate (ORR)	ORR was defined as the percentage of participants with a best overall response of complete response (CR) or partial response (PR) based on iRECIST. CR was defined as disappearance of any intratumoral arterial enhancement in all target lesions. PR was defined as at least a 30% decrease in the sum of diameters of viable (enhancement of arterial phase) target lesions taking as reference to the baseline sum of the diameters of target lesions.	6 months
Secondary	Adverse Events	Number of adverse events. Postoperative adverse events were graded based on CTCAE v4.03	6 months
