[Application and progress of ablation therapy for large liver cancer].

Primary liver cancer is one of the most common malignant tumors. A liver tumor is defined as a large cancer when its diameter is ≥5 cm. Resection surgical therapy can be performed only on a small portion of large cancers because of its own features. As a result, non-resection surgical therapy has become a hot and difficult issue of widespread concern. In recent years, with the development of ablation technology, research on the use of ablation alone and ablation combined with other modalities for the treatment of large liver cancer has continued to deepen, and good clinical results have been achieved. Although there are many reports on ablation treatment for large liver cancer, there are currently no standardized treatment guidelines, and there are still controversies about treatment strategies. This article reviews the development of ablation therapy, the current status of single and combined ablation therapy, the prevention of related complications, and other aspects of large liver cancer.
