Liver cancer is one of the common malignant tumors. The development of liver cancer is closely related to chronic hepatitis (hepatitis B), and also related to aflatoxin, nitrosamines, parasitic infections, environmental pollution, genetic factors and so on. The symptoms of liver cancer can be manifested as: swelling and pain in liver area, enlargement of liver, loss of appetite, nausea, vomiting, jaundice, wasting, etc. Common treatment methods of liver cancer include surgery, radiotherapy and traditional Chinese medicine. The early symptoms of liver cancer are not obvious, and usually patients and friends with liver cancer are found in the middle and late stages of liver cancer. At present, in China, interventional therapy has become the first choice for the treatment of middle and late stage liver cancer (especially for patients who have lost the chance of surgery) because of its minimally invasive and high efficiency, and has been well received by patients and friends. It is simple and easy to operate, safe and reliable. The skin incision is only about 2mm, and the patient suffers less pain. It can be performed especially for the old and frail patients and those with certain diseases, without general anesthesia, and the patient remains awake during the whole treatment. The therapeutic effect is precise. Interventional treatment for advanced hepatocellular carcinoma is not restricted by the metabolic cycle of tumor cells, and can be performed in stages, multiple times and repeatedly against multiple or recurring tumor nodules according to the condition and treatment needs; successful treatment can see rapid decrease of AFP, shrinkage of tumor and pain relief, etc. The local drug concentration of interventional therapy is tens of times higher than that of systemic chemotherapy, and there is no problem of drug resistance, and the side effects are small; interventional therapy for advanced liver cancer can achieve precise localization and accurate treatment, directly cut off the blood supply of tumor and “starve” the tumor cells to death, with little damage to normal tissues. Interventional treatment for liver cancer is under the monitoring of modern imaging equipment (DSA), which can accurately evaluate the efficacy in real time. Recovery is fast: normal activities are usually possible 24 hours after surgery; for some liver cancers, they can be resected in two steps after volume reduction. The survival period of patients with intermediate and advanced hepatocellular carcinoma is significantly prolonged and the quality of life is significantly improved after interventional treatment.
