Microwave Ablation: Principles and Techniques

Tumor ablation is defined as the direct application of chemical or thermal therapies to a tumor to achieve eradication or substantial tumor destruction. Currently, minimally invasive ablation techniques have become available for local destruction of focal tumors in multiple organ sites. Microwave ablation is based on biological response to tissue hyperthermia for solid tumor treatment with relatively low-risk procedure. Because of several advantages including higher thermal efficiency, higher capability of coagulating blood vessels, faster ablation time, and simultaneous application of multiple antennas, microwave ablation could be a promising minimally invasive ablation technique for the treatment of solid tumors. The aim of this chapter is to review the basic principles and the state of the art of different device technologies, approaches, treatment strategies, current therapeutic status, and future trends of microwave ablation for solid tumors.
