Different interventional treatment plans suitable for each patient are formulated according to the type and size of tumor, the presence or absence of portal vein cancer embolism, the degree of cirrhosis, liver function status, age and systemic condition. For example, for elderly patients with hepatocellular carcinoma (≥65 years old) or those with severe cirrhosis, they should choose to be cannulated in the tumor feeding artery and given simple chemoembolization; while for patients with hepatocellular carcinoma who are found to have dense iodine oil deposition in most of the lesions with only small marginal iodine oil defects during the follow-up after TAE, radiofrequency ablation can be performed under ultrasound guidance or CT guidance. The interval of interventional treatment depends on the follow-up. Usually, the interval between each intervention is 50 days to 3 months, and in principle, it is at least 3 weeks from the recovery of the patient after the last intervention. If there is dense iodine oil deposition in the liver tumor lesions, necrosis of tumor tissues and no new lesions or new progress, then interventional treatment is not allowed for the time being. Comprehensive treatment in the interval of interventional therapy: it is appropriate to adopt liver protection, improve immunity and Chinese medicine to support the root. 1. Traditional Chinese medicine: 2 weeks after intervention, the application can be started. The principle is to support and consolidate the essence, replenish qi, improve immunity and regulate. Forbid the use of poison against poison, softening and dispersion, activating blood stasis, clearing heat and detoxifying drugs. 2, measures to improve immunity: interferon, thymidine, interleukin II, tumor necrosis factor, LAK cells, mushroom polysaccharide, etc. Can be used alone or in combination with 2 to 3 drugs.
