a. Comparison of local tumor progression (LTP) after ablation under local anesthesia (LA) and general anesthesia (GA). The mean LTP was 33.434 months (95% CI: 31.133, 35.734) in GA versus 31.132 months (95% CI: 28.535, 33.730) in LA (p = 0.230, log-rank test). The 12-, 24-, and 36-month LTP rates in GA were 94.1, 87.9 and 74.4%, respectively, and the 12-, 24-, and 36-month LTP rates in LA were 94.7,84.2 and 62.1%, respectively. b. Comparison of different anesthesia methods on LTP of tumor in challenging locations. The mean LTP was 32.055 months (95% CI: 28.973, 35.138) in GA versus 26.551 months (95% CI: 22.049, 31.053) in LA (p = 0.180, log-rank test). The 12-, 24-, and 36-month LTP rates in GA were 100.0, 76.0 and 48.4%, respectively, and the 12-, 24-, and 36-month LTP rates in LA were 88.9,66.7 and 35.4%, respectively.(Note: challenging locations--Hepatic dome, close to the heart/diaphragm/hepatic hilum)
