Measure
Patients Treated With Radiofrequency Ablation (RFA)
RFA treatment: Computed tomography (CT) was used to treat tumors under general anesthesia. Thoracic epidural anesthesia was administered in case of contraindication to general anesthesia mostly due to poor respiratory function. All patients were treated with the same multitine electrodes (LeVeen; Boston Scientific, Nattick. MA) measuring 3, 3.5, or 4 cm in diameter and at least 10 mm larger than the diameter of the target tumor. Multiple overlapping ablations were performed, when needed, in different parts of the tumor in order to cover the entire volume.

PRIMARY outcome

Timeframe: one year after percutaneous radiofrequency ablation (RFA)

Population: Patients alive at one year

local control is defined as the absence of progression of the ablated site. rate is defined as the number of alive patient without local progression divided by the number of patients alive at one year.

SECONDARY outcome

Timeframe: three years after percutaneous radiofrequency ablation (RFA)

Population: Patients alive at three years

local control is defined as the absence of progression of the ablated site. rate is defined as the number of alive patient without local progression divided by the number of patients alive at thee years.

Local Tumor Control Rate 3 Years After Percutaneous Radiofrequency Ablation (RFA)
3 Participants

SECONDARY outcome

Timeframe: 1 year after RFA

OS was defined as the time from RFA treatment to death, whatever the cause. If the patient was still alive at the end of study or lost to follow-up, the patient was censored at the date of last news. 1-year overall survival rate was estimated using the Kaplan-Meier estimator.
