RFA and cryoablation expand treatment of hepatic tumors

Ablative techniques have greatly improved physicians' ability to definitively treat patients with primary and secondary hepatic tumors. These techniques include radiofrequency ablation (RFA) and cryoablation, as well as newer microwave and laser ablation methods. Ablation devices, used either alone or combined with hepatic resection, have made it feasible to treat patients with bilobar lesions and those who would not tolerate liver resection due to underlying comorbidities.
