Surveillance programs and widespread use of medical imaging have increased the detection of hepatic tumors. When feasible, surgical resection is widely accepted as the curative treatment of choice, but surgical morbidity and mortality has spurred the development of minimally invasive ablative technologies over the last 2 decades. Microwave ablation has emerged as a promising thermal ablation modality with improving oncologic efficacy due to technical improvements and image guidance strategies. This article provides an overview of microwave application in liver tumors, and we discuss currently available equipment, clinical efficacy, and safety and provide comparisons with other commonly used therapies. This article also introduces advanced ablative techniques and combination therapies that may help achieve precise ablation and further enhance the efficacy of microwave ablation.
