Interventional therapy is an important means of treating liver cancer, because of the direct injection of drugs into the tumor, or the tumor feeding vessels were embolized directly and plays a role in the treatment or tumor necrosis, widespread clinical application. A liver cancer patients who have been hospitalized ninth times of interventional treatment in patients with the doctor said: "I use interventional therapy for patients, you are one of the most times of treatment, is nine times of interventional treatment in patients with the first." However, the higher the frequency of intervention treatment, the higher the survival rate? In fact, interventional therapy is a minimally invasive treatment application of modern high-tech means, which is under the guidance of medical imaging equipment, the special catheter, guide wire and other precision instruments is introduced into the body, the diagnosis and treatment of local lesions in vivo. Most of the projects are carried out in interventional therapy of blood vessels, it does not need the surgery, only a small grain of rice to cut, the thin tube is inserted into the blood vessel can treat many past treatment, must be poor surgical treatment or medical treatment of the disease. Hepatocellular carcinoma (HCC) is one of the 10 most common malignant tumors in the world, with an annual incidence of 260 thousand cases, of which about 42.5% are in China, and the incidence is increasing in recent years. At present, although the early diagnosis rate of liver cancer has been raised, but still in the clinical stage of advanced liver cancer, the survival rate of patients with liver cancer is still not high. In general, the traditional treatment of liver cancer surgery, systemic chemotherapy or radiotherapy. Since the last century since 80s the use of interventional therapy for hepatocellular carcinoma, with small trauma, quick recovery and good curative effect, quickly became popular with lots of patients, the clinical results of 20 years show that interventional therapy is superior to the traditional method of treatment, has become the preferred method for the treatment of liver cancer. Some of the patients in the hospital for the treatment of the number of times as many as a dozen times, the purpose of liver cancer treatment is to reduce the pain of patients, prolong life, inhibit tumor metastasis and recurrence. Some scholars believe that the long-term curative effect of interventional therapy of liver cancer is not very ideal, mainly the problem of metastasis and recurrence. It was found that the original lesion was reduced and the embolic agent was filled in the clinical work, but after a period of time, there was a new lesion around the lesion. More than 3 times or too short interval can cause serious stenosis or occlusion of hepatic artery and gastrointestinal toxicity and other adverse reactions, which seriously affect the survival rate. In principle, it is possible to kill tumor cells as much as possible and to minimize the damage to normal hepatocytes, but their objective criteria are to be discussed and standardized. So the liver cancer is not more for the better, still need to be combined with personal condition analysis and judgment, and to achieve the best treatment effect.
