The so-called “interventional” therapies refer to the treatments that are carried out by entering the body in a certain way, which can be generally categorized into radiological interventions and ultrasound interventions. Radiological intervention: chemotherapy + embolization Radiological intervention refers to the positioning of radiation irradiation, the catheter through the peripheral artery (usually the femoral artery at the root of the thigh or the radial artery at the wrist) into the blood vessels supplying the liver, and the catheter injection of drugs to carry out the treatment, which mainly includes chemotherapy and chemotherapy plus embolization. Embolization refers to an interventional procedure in which the blood vessels supplying the liver tumor are simultaneously occluded with special materials, causing the tumor to become ischemic and necrotic. At this point, chemotherapy is completed by means of intervention. Liver tumors are usually treated more often with chemotherapy after surgery, and the latter (chemotherapy + embolization) is used for those patients who require simultaneous embolization. Adverse effects are sometimes seen, usually fever, iodine allergy, bleeding, infection, broken blood vessels and chemotherapy-related side effects, but the incidence of these adverse effects is not high. Ultrasound intervention: not related to chemotherapy Ultrasound intervention refers to the treatment of intrahepatic tumors by percutaneous puncture under ultrasound localization, which may include injection of anhydrous alcohol into the tumor, cryotherapy, microwave therapy, radiofrequency therapy, etc. It is generally applicable to the patients who are unable to undergo surgery due to contraindications, some of the patients with small hepatocellular carcinomas or some of the patients with intrahepatic metastases, and the specific plan shall be decided by consulting with the liver surgeon specializing in liver surgery. In this case, “interventional” treatment is not related to chemotherapy.
