Liver cancer is one of the most common malignant tumors, and its incidence rate ranks third after stomach cancer and esophageal cancer. There are about 300,000 to 1 million new cases of liver cancer worldwide each year, and about 260,000 deaths annually, of which China accounts for 42.5%. Currently, the prevention and treatment of liver cancer has been included in the prevention priorities of China. Most of the patients in China have lost the opportunity of surgical resection when they are diagnosed with liver cancer. In the mentality of seeking medical help in an emergency and being deceived by bad advertisements, many patients have spent a lot of money but have not received proper treatment. In fact, the current treatment plan for liver cancer has been relatively standardized, and there are clear regulations on what treatment to be done in what period. Of course, with the development of medical technology level, many of the plans are continuously updated. The Chinese Medical Association has further revised the 2011 version of primary liver cancer treatment protocols and released the 2017 version of primary liver cancer treatment protocols in June this year, which includes three precise weapons that play an important role in liver cancer treatment! With the help of ultrasound, CT or DSA equipment, doctors can use special puncture needles to directly puncture through the skin to the liver lesion area to directly destroy and kill the lesion! This method can be divided into three ways. 2.Transcatheter hepatic artery embolization chemotherapy TACE treatment is currently recognized as one of the most common methods for non-surgical treatment of liver cancer. 3.Internal radiation therapy Internal radiation therapy refers to the implantation of radioactive particles into the lesion. Radioactive particles can continuously produce low-energy X-rays, γ-rays or β-rays, and after the radioactive particles are implanted in the tumor tissues or in the ductal lumen (portal vein, inferior vena cava or bile duct) invaded by the tumor, the tumor cells are killed to the maximum extent by continuous low-dose radiation. Particle implantation techniques include intertissue implantation, portal vein implantation, inferior vena cava implantation, and intra-biliary implantation to treat intrahepatic lesions, portal vein cancer thrombosis, inferior vena cava cancer thrombosis, and intra-biliary cancer or cancer thrombosis respectively.
