Summary

Increasing ablative zone is an essential part to improve technical success and long term outcome in patient treated with radiofrequency ablation (RFA).

A combination of dual switching system and separable clustered electrode has been reported to create large ablative zone in preclinical study.

Based on preclinical study, the investigators conducted a preliminary study in eligible 60 patients to measure whether this combination (dual switching system and separable clustered electrode) improves technical success rate and local tumor progression rate over a year, in comparison with historical control group.

Monopolar RFA using dual switching mode (DSM)

DEVICE

separable clustered electrode

A separable clustered electrode is similar to a clustered electrode, although it differs from a conventional clustered electrode in that each individual electrode is separable.
