Overlapping microwave ablation has been widely used in treating large liver tumors, and more and more researchers are focusing on this therapy strategy to expand its clinical application. This paper reviewed the therapeutic schemes, simulation techniques, in vitro experimental results and coagulation zone evaluation techniques for large tumor overlapping microwave ablation, to evaluate the effectiveness of different multi-antenna treatment schemes. The prospect and challenge of overlapping microwave ablation in the clinical treatment of large tumors were further discussed.
