Stereotactic Body Radiotherapy Versus Radiofrequency Ablation for Unresectable, Small (≤ 3 cm) HCC

"* Verify the setup position and respiration of patients as in the simulation CT image.~* To precisely align the tumor prior to each treatment, cone-beam CT and gated fluoroscopy using the On-board Imager mounted on the linear accelerator are performed.~* The Real-time Position Management system is used to monitor the accuracy of breathing phase during treatment."

\- RFA are performed under local anesthesia or monitored anesthesia care with either a 15-gause or 17-gause internally cooled electrode, depending on the size of the tumor.
