Liver cancer is one of the common malignant tumors in China, which is highly malignant and progresses rapidly. Therefore, the treatment of liver cancer is difficult and ineffective. The development of interventional radiology has provided many new and effective treatment methods for liver cancer. Since the 1990s, the Department of Interventional Oncology has carried out transcatheter hepatic artery embolization chemotherapy (TACE) for the treatment of hepatocellular carcinoma, and has treated more than 3000 patients so far with good results. The vast majority of treated patients can survive for more than 2 years, and some can even live for 5-6 years. tACE involves inserting a catheter into the blood supply artery of liver tumor, performing chemotherapy and embolization to block the nutrition of the tumor. In recent years, after TACE of liver cancer, sequential treatments such as percutaneous puncture anhydrous alcohol injection ablation (PEI), 125I radioactive particle implantation, microwave, argon helium knife and other local ablation are performed. 125I radioactive particle implantation is performed by puncturing the liver with a special needle through the skin under CT scan to reach the tumor tissue, and implanting a 125I radioactive particle as large as a grain of rice evenly into the tumor. Hepatic artery embolization chemotherapy combined with 125I radioactive particle implantation and local ablation such as microwave and argon helium knife can receive better treatment effect. Lung cancer has a high incidence and mortality rate. According to the different stages, physical conditions and age of patients, the department formulates appropriate treatment plans for each patient according to the principles of evidence-based medicine, and adopts various minimally invasive treatment techniques such as bronchial artery chemotherapy or embolization, 125I radioactive particle implantation, radiofrequency, microwave or argon helium knife and immunotherapy, which have achieved excellent treatment results. achieve the purpose of radical treatment.
