Combination of SFRT, PD-L1 Inhibitor, and Anti-VEGF in Advanced Hepatocellular Carcinoma

Patients received intravenous PD-1 inhibitor 200mg(Camrelizumab, Tislelizumab, or Sintilimab) plus oral Apatinib 250 mg or Lenvatinib 12mg (for bodyweight ≥60 kg) or 8 mg/kg (for bodyweight \<60 kg) daily, and additional SFRT for primary liver tumor. PD-1 inhibitor is administered for 2 years or until disease progression or intolerance. Anti-VEGFR is continued until disease progression or intolerance. SFRT implementation plan is as follows: The GTV consists of 2-5 sub-target volumes, which are cylindrical shapes with a diameter of 1.6cm, a height of 2cm, and an interval of 3-5cm. The total volume of the GTV is about 8-20cc, and the distance between the GTV and the OARs is greater than 2cm. The prescribed dosage for each course of radiotherapy is 24 Gy in 3 daily fractions (8Gy x 3F), with a 3-week interval between courses (Q3W). The total courses of radiotherapy shall not be less than 2 (depending on the efficacy and cumulative dose of OARs).
