Comparison Between Radiofrequency Ablation and Hypofractionated Proton Beam Radiation for Recurrent/Residual HCC

"\* RFA(radiofrequency ablation )~* RFA electrode: Cool-tip RF ablation system (Covidien plc, 20 Lower Hatch Street Dublin 2, Ireland) and Well-Point RF Electrode (STARmed, Koea)~* performed using either the manufacturer's standard algorithm or an interactive algorithm, with the latter being used when the impedance did not begin to increase at the midinterval of the standard algorithm~* the duration of a single RFA session was 10 min to 15 min."

"\* Proton~66 GyE /10 fx, 6.6 GyE fraction dose, 5 days/week, for HCC free from the alimentary tract (i.e., stomach, duodenum, esophagus, small and large bowel) (more than 2cm from clinical target volume),TLV30\<40%,and/orRLV30\<30%)"
