Hepatitis, liver cirrhosis and liver cancer is a high incidence area in china. Primary liver cancer is the third most common malignant tumor in china. As far as the radical treatment of liver cancer is concerned, there are a lot of problems in the medical field and the patients. Radiofrequency ablation for the treatment of primary liver cancer has been ten years of history, this technology has been widely used in the clinical treatment of liver tumors and research, has become a relatively mature technology for the clinical treatment of liver cancer.
Radiofrequency ablation is a minimally invasive tumor in situ treatment technology, with the help of image positioning technology and ultrasound or CT guided needle electrode is directly inserted into the tumor, the lesion tissue by RF energy to produce high temperature drying, the final solidification and inactivation of soft tissue and tumor. The principle is electronic generator to generate RF current, so that the surrounding tissue through the needle electrode to produce high speed ion vibration and friction, and then transformed into heat and outward over time conduction, thus local tissue coagulation necrosis and degeneration. The current technique uses a single electrode needle for radiofrequency ablation to produce a maximum diameter of 5cm coagulation necrosis. The clinical observation on radiofrequency ablation has a good effect in the treatment of liver tumor, according to a report in the treatment of primary liver cancer patients after treatment 1, 2, 3 and 5 year survival rates were 94%, 86%, 68% and 40%, the effect is similar to the surgical radical resection effect. At the same time, it achieves the goal of minimally invasive and radical treatment of liver cancer. The medical profession is now due to the treatment of radiofrequency treatment of liver cirrhosis patients with small hepatocellular carcinoma or some very serious patients have had some change and controversy, but these patients choose radiofrequency ablation therapy in the clinical treatment shows more and more advantages.
