A combination therapy of ethanol injection and radiofrequency ablation under general anesthesia for the treatment of hepatocellular carcinoma

Figure 1 Relationship between the volume of coagulated necrosis induced and the amounts of ethanol injected or total applied energy or the product of the amounts of ethanol and the total applied energy. All the amounts of ethanol, total applied energy, or the products of the amount of ethanol and total applied energy showed a significant positive correlation with the volume of coagulated necrosis. (Ethanol vs volume, r = 0.54, P = 0.018; energy vs volume, r = 0.61, P = 0.0057; ethanol × energy vs volume, r = 0.61, P = 0.0078).
