The Progress of Radiofrequency Ablation for the Treatment of Liver Cancer

Liver cancer is one of the common malignant tumors in our country. So far, among several different theraputic methods of liver cancer, surgical treatment is still the first choice due to its better survival rate. However, many patients are in late period already when diagnosed with liver cancer, so they are no longer suitable for surgery as their residual liver tissue can't compensate or the because of the poor general condition. Based on the situation, now a lot of non-surgical treatments have been widely used in clinical. The radiofrequency ablation treatment for liver cancer, as a non-operative treatment, which is minimally invasive, has good curative effect, fewer complications, better security, and can be repeatedly used, has become a common means for the treatment of liver cancer in recent years.Radiofrequency ablation of liver cancer can be divided into open rf, rf cavity mirror, and imaging guided percutaneous radiofrequency,etc. Treatment can be radiofrequency therapy alone, or combined with interventional treatment, alcohol injection, or intravenous systemic chemotherapy, etc. Here we will review several aspects of the technology, from the principle of radiofrequency ablation treatment for liver cancer, to indications, way, complications, and prognosis.
