Abstract

In comparison to traditional cancer treatment methods, such as surgery and chemotherapy, the radiofrequency ablation (RFA) provides great advantages of minimally invasive and cost-effective therapy with a short hospital stay. In addition, RFA also can be used for patients inoperable for surgery or chemotherapy. In the last century, scientists have dedicated themselves to enlarging the ablation size by designing various electrode shapes and combining conventional treatments. This mini-review aims to illustrate the history of RFA technology, the structural design of the electrode geometries, the auxiliary method to enhance the ablation lesion size and minimize cancer reoccurrence, and the current challenges to RFA and their potential solutions.
