A baseline core tumor biopsy and peripheral venous blood will be collected from eligible participants at screening, and sample tumor tissue from the surgical specimen and PBMC (peripheral blood mononuclear cell) will be snap-frozen and stored for the future relevant studies.~Eligible patients will receive SBRT (8 Gy × 3 fractions, every other day) on day 1, day 3 and day 5; the first dose of Tislelizumab will be administrated concurrently on day 1, then the second on day 22 (the first day of week 4, ± 3 days). Then on day 50 (the first day of week 8, ± 7 days), curative liver resection of HCC will be scheduled.~Patients will be reviewed following completion of SBRT and tislelizumab treatment (Follow-up visit 1; FU1) prior to surgery.~Response Evaluation Criteria in Solid Tumors, version 1.1 (RECIST v1.1) and HCC-Specific mRECIST criteria will be used to determine patient response to treatment, including CR (complete response), PR (partial response) and ORR (objective response rate). PBMC will be collected again and stored.~Hepatic resection will be performed as per standard of care. The safety FU2 will be conducted after the first dose of the post-resection tislelizumab. All AEs that occur prior to the visit will be recorded. Participants with on-going AEs at the visit will be followed up by principal investigator (PI) or delegate until resolution or stabilization of the event. Following FU2, participants will be assessed every 3 months (±7 days) thereafter to collect information regarding disease status and survival. Long-term follow-up will continue, for each patient, for a total of 5 years.
Notable-HCC is a phase Ib study of neoadjuvant stereotactic body radiotherapy (SBRT) plus Programmed cell death-1 (PD-1, Tislelizumab, BeiGene) prior to hepatic resection in patients with resectable HCC.
