Hepatocellular carcinoma is one of the common malignant tumors in clinical practice. It starts insidiously and often reaches advanced stage when patients have symptoms. According to statistics, the average survival time of liver cancer patients without treatment is about 3 months, which is why it is called “the king of cancer”. In the past, systemic chemotherapy was mainly used for liver cancer that could not be treated surgically, but liver cancer is not highly sensitive to chemotherapy and is prone to systemic side effects such as vomiting, hair loss and bone marrow suppression, which are difficult for patients to tolerate and have poor efficacy. Interventional therapy is a treatment method for hepatocellular carcinoma that emerged in the 1980s. Its main method is to insert a thin special catheter of about 2mm in diameter from the femoral artery to the hepatic artery under fluoroscopic surveillance and slowly infuse chemotherapeutic drugs into the tumor vessels. The incidence of systemic side effects is extremely low. After local chemotherapy, if the patient’s condition allows, iodine oil and gelatin sponge particles can be injected into the tumor blood vessels to block the tumor blood vessels and make the tumor ischemic and necrotic. When embolizing the tumor vessels of liver cancer with iodine oil, doctors often mix chemotherapeutic drugs with iodine oil to form an emulsion. Some people wonder if hepatic artery embolization will damage the liver function of patients? Generally speaking, the effect is not significant, because firstly, there are two sources of blood supply to liver, one is hepatic artery and the other is portal vein, and more than 90% of blood supply to most hepatocellular carcinoma comes from hepatic artery, while 70% of blood supply to normal liver tissue comes from portal vein and only 30% from hepatic artery. Secondly, in the process of embolization, the doctor usually tries to insert the catheter into the artery supplying the tumor, so as to avoid embolization of normal liver tissue. After the above treatment, the catheter is removed, the femoral artery puncture site is compressed for about 10 minutes to stop bleeding, and then pressure bandaged. The patient can be released from the gauze and bandage and out of bed after 24 hours of lying flat, leaving no surgical incision and minimal pain. Most of the patients will experience pain and fever in the liver area within 1 week after the operation, which is due to tumor necrosis and can be improved with anti-inflammatory and analgesic drugs. The above interventional treatments are applicable to liver cancer, liver metastases, and other solid tumors such as kidney cancer, gastric cancer, lung cancer, bone tumors and pelvic tumors that cannot be removed surgically. For recurrent liver cancer after surgery, interventional therapy is also the preferred treatment method. The emergence of this treatment method has greatly prolonged the survival period of liver cancer that cannot be surgically resected. Current statistics show that the 5-year survival rate is about 60%, the 3-year survival rate is about 30%, and a few cases can survive for 5 years or even be cured. For small hepatocellular carcinoma, its therapeutic effect is also very good, and its therapeutic effect can be comparable to that of surgical resection, which can save patients from the pain of surgical treatment. It should be noted that the key to liver cancer treatment is early detection and early treatment. For early stage liver cancer, both surgical and interventional treatment have good effects. People with high risk of liver cancer, such as patients with cirrhosis and hepatitis, should undergo ultrasound examination every six months to a year to detect the occurrence of liver cancer as early as possible. In addition, to prevent the occurrence of tumor, it is also a good habit to drink less alcohol, combine work and rest, have a regular life and do not overwork.
