This study aimed to evaluate the efficacy and safety of camrelizumab plus apatinib with or without stereotactic body radiotherapy (SBRT) as first-line therapy for patients with hepatocellular carcinoma (HCC) with portal vein tumor thrombus (PVTT).

Patients and Methods:

This is a multicenter, open-label, noncomparative, randomized trial that recruited patients with HCC with type II/III/IV PVTT, who had not previously received systemic therapy. Patients were randomly assigned (2:1) to receive camrelizumab (200 mg, every 3 weeks) and apatinib (250 mg, every day) with or without SBRT [95% planning target volume (PTV), 36–40 Gy/6–8 Gy]. The primary endpoint was overall survival (OS), and the secondary endpoints were progression-free survival (PFS), objective response rate (ORR), disease control rate (DCR), duration of response, time to progression, and safety.


Sixty patients were enrolled and randomly assigned to two prospective cohorts. Median OS were 12.7 months [95% confidence interval (CI), 10.2–not available (NA)] and 8.6 months (95% CI, 5.6–NA), and median PFS were 4.6 months (95% CI, 3.3–7.0) and 2.5 months (95% CI, 2.0–7.6) for the SBRT and non-SBRT cohorts, respectively. The ORR and DCR were 47.5% and 72.5% in the SBRT cohort, and 20.0% and 40.0% in the non-SBRT cohort. The most common treatment-related adverse events of any grade were hypertension (55.0%), hand-foot syndrome (51.7%), and leukopenia (50.0%). Grade ≥ 3 was reported in 13 (21.7%) patients.


First-line treatment with camrelizumab–apatinib combined with or without SBRT showed clinical benefits in patients with HCC with PVTT, with an acceptable safety profile. Thus, these combination regimens may be potential options for such patients.
