Term | Definition |
---|---|
Technical success | Ablation protocol completed and tumor covered (on immediately post-ablation CT) |
Complete ablation(Technique effectiveness) | Ablation defect covering the entire tumor on the 4–6 week post- ablation CT |
Local Tumor Progression | Evidence of tumor recurrence (progression) in the previously ablated area by CT criteria
|
Primary LTP-free survival | Time period between the initial RF Ablation and the first radiologic evidence of LTP |
Assisted LTP-free survival | Cumulative time interval between the first RF ablation and the latest radiologic follow-up showing evidence of LTP (local tumor recurrence); includes all the ablations performed for the treatment of the same target tumor to treat LTP |
Overall Survival | Time period between the initial RF ablation and patient’s death from any cause, or most recent follow-up |
Clinical Risk Score (CRS) modified for Ablation Patients with 0-2 points: low risk Patients with 3–4 points: high risk |
