Early stage hepatocellular carcinoma is mainly treated by surgical resection, however, the onset of hepatocellular carcinoma is insidious and the malignancy is high, and patients are mostly in the middle and late stages when they are diagnosed, so the success rate of surgical resection is low, and non-surgical treatment is mostly adopted. With the development of vascular interventional radiology, transcatheter hepatic artery chemoembolization (TACE), as the main method, has become the first choice of non-surgical treatment for hepatocellular carcinoma. Transcatheter hepatic artery chemoembolization is to selectively insert the blood supply artery of hepatocellular carcinoma through the femoral artery for embolization and infusion of chemotherapeutic drugs to embolize the main tumor vessels to block the blood supply of the tumor to cause ischemia and necrosis, and to infuse chemotherapeutic drugs to kill the tumor cells. Advantages: less invasive, less side effects, can be repeatedly treated, improve survival quality and prolong life. The efficacy of chemoembolization combined with radiofrequency ablation for early-stage hepatocellular carcinoma has shown that the long-term survival and disease-free survival rates are similar to those of surgical resection alone, and TACE combined with other treatments has the potential to become an alternative treatment to surgery, bringing new hope for patients with unresectable tumors. Indications: Applicable to primary hepatocellular carcinoma, recurrence of hepatocellular carcinoma after surgery (liver function Child classification of A, B-). Interventional efficacy of hepatocellular carcinoma: It is mainly related to the malignancy degree and biological behavior of the primary tumor. The survival period of untreated patients with middle or late stage of hepatocellular carcinoma is 3-6 months; interventional treatment enables patients to survive with tumor, and literature reports that the survival period of middle or late stage of hepatocellular carcinoma can be significantly prolonged after interventional treatment.
