Outcome Measures

Primary Outcome Measures

  1. safety rate [The period to evaluate DLT is for 28 days after completion of SBRT.]

    In stage 0 and stage I interim analysis DLT will be assessed after 3 patients for each stage are accrued to the study. In stage II interim analysis for 6 (from stage 0 and I) + 6 (from stage II) patients, ≤4 patients with DLT and ≥6 patients with CR/PR are the criteria for stage III patient accrual.

  2. objective response rate [From date of study intervention to 2.5 years]

    Tumor measurements and response evaluations are conducted by an independent radiologist based on liver dynamic CT or MRI images at screening and every follow-up image after allocation. A second radiologist will perform an independent blinded image review at the end of the study without interfering with the primary judgment concerning disease progression and treatment decision. The response evaluation criteria are according to mRECIST.

Secondary Outcome Measures

  1. Progression-free survival and overall survival [From date of study intervention to 2.5 years]

    Survival outcomes are calculated from date of allocation. Progression is defined as progressive disease by mRECIST or death from any cause. Overall survival is the time from allocation to death from any cause. Survival curves are determined by the Kaplan-Meier method.

Other Outcome Measures

  1. Immune biomarkers [From date of study intervention to 2.5 years]

    Pre-treatment tumor tissue (i.e., biopsy or prior surgery) or blood sample is mandatory for biomarker study accompanying the clinical trial. The collected biomarkers will be analyzed for the correlation with the response of portal vein tumor thrombosis, progression-free survival, and overall survival.
