Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Liver enhanced MRI or CT and contrast-enhanced ultrasound were reviewed within 4 \~ 6 weeks after the first ablation treatment to evaluate the complete response rate of the tumor after treatment. Patients suspected of local incomplete ablation in either of the two examinations could receive a salvage ablation for once within 12 weeks of the first ablation, but no extra dose of PD-1 antibody would be given. Patients with residual viable tumor after re-ablation were defined as treatment failure.
The first six patients (stage I) underwent detailed physical examination on the 2nd, 7th, 14th and 21st days after receiving the first dose of study drug, and 30 days after the 2nd and 4th doses of study drugs. Blood tests and urine routine were performed on the 2nd day after treatment, as well as ECG examination. In the second stage, the patients underwent examinations on the second and 21st days after the dose of study drug, and on the 30 days after the last dose of study drug (the above examination can be carried out within ± 7 days). If there are clinically significant study related adverse events (including abnormal test results) in patients in stage I, necessary reexamination and visit would be added in patients in stage II.
Radiological evaluation arrangement: liver enhanced MRI or CT and contrast-enhanced ultrasound were performed within 4 \~ 6 weeks after the first ablation. The second imaging examination would be completed within 4 \~ 6 weeks after the end of the study treatment, and then examined according to the following schedule: CT / MRI was repeated every 3 months within the first year, then every 4 months within the next year, and every 6 months after 2 years. The investigators will evaluate the adverse events during the follow-up. After the patients have radiologically confirmed recurrence and/or metastasis, they will be treated according to the guideline without limitation. The information of all anti-cancer treatments they received need to be collected.
Follow-up by phone will be conducted at least every 6 months until death to find out the patient's survival data, as well as their physical condition and information about other anticancer treatment received.

Study Groups

Radiofrequency or microwave ablation combined with PD-1 monoclonal antibody
Patients who meet the inclusion criteria will receive 1 cycle of PD-1 antibody on the day before ablation, then 3 cycles of PD-1 antibody after primary radiofrequency or microwave ablation, on a schedule of per 3 weeks, then be followed until disease relapse or death.
PD-1 monoclonal antibody
The enrolled patients received intravenous injections of PD-1 monoclonal antibody (Tislelizumab 200mg) on the 1 day before radiofrequency or microwave ablation treatment, and 21(±7) days, 42(+7) and 63(+7) after ablation.
Radiofequencey or microwave ablation
The enrolled patients received primary radiofrequency or microwave ablation on the day after the first dose of PD-1 antibody treatment.
