Study Details
Study Description
Brief Summary
This study will document for the safety and efficacy of image guided multi-mode precision ablation system (the combination of cryoablation and radiofrequency ablation) for the treatment of liver malignant, as well as provide the indicator of antitumor immune response for liver malignant in China.

Detailed Description
Either Cryoablation or Radiofrequency Ablation has been well accepted and widely used in clinical practice for solid tumor treatments with various commercial systems. Previous studies have established that locally exerting great thermal and mechanical stress through alternating freezing and heating abruptly broke the tumor cells and micro-vasculature in situ, enabling complete damage of primary tumor. Large amount of biological stimuli was released during this process to enhance body anti-tumor immunological response. This method thus may inhibit distal metastases and increase the survival rate. The investigators hypothesized that multi-mode thermal method (the combination of cryoablation, radiofrequency ablation) might trigger a whole body anti-tumor immune response for malignant tumor basing on multi-scale bio-thermal responses at molecular, cellular, tumor angiogenesis and tissue levels. The purpose of this study was to prospectively investigate the safety and feasibility of multi-mode precision ablation system for the treatment of liver malignant.

Outcome Measures
Primary Outcome Measures
- Local control rate [From date of randomization until the date of progression of ablation lesion, assessed up to 5 years.]
Contrast enhanced CT or MRI was performed to evaluate Local tumor control
Secondary Outcome Measures
- Overall survival (OS) [From date of randomization until the date of death, assessed up to 5 years.]
Overall survival is defined as the time (in months) from the date of randomization to the death date.
- Progression free survival (PFS) [From date of randomization until the date of first documented progression, recurrence or date of death from any cause, whichever came first first documented progression or date of death from any cause, whichever came first, assessed up to 5 years.]
Progression-free survival is defined as the time (in months) from the date of randomization until the date of the Investigator-assessed radiological disease progression or death due to any cause.
- Complication rate [6 months]
Number of participants with adverse events and complication
