Patients with hepatocellular carcinoma can choose interventional treatment to control tumor development with relatively very good results, especially for patients with intermediate to advanced stage and progressive liver malignancies. Because patients in this period have lost the best chance of surgical treatment, choosing interventional treatment is relatively simple, inexpensive and easy to operate. Hepatic artery cannulation with perfusion chemotherapy is usually performed, radiofrequency ablation is also an option, and interventional therapy can be performed multiple times. During the treatment period and interval, attention should also be paid to monitoring the changes of liver function indexes and giving symptomatic treatment such as liver protection. Patients with liver malignancy usually have liver function abnormalities, such as increased bilirubin and transaminases.
