What is the choice of interventional therapy for different stages of liver cancer? Since the 1980s, interventional therapy has been widely used in the treatment of liver cancer in our country, and our understanding of this area has been very profound and the technology is quite mature. Although there are still many academic differences in the understanding of the period and stage of interventional treatment for liver cancer patients, the general trend now is that interventional treatment should be preferred for primary liver cancer that cannot be removed surgically. It does not matter whether the patient is in early, middle or late stage, as long as the patient cannot be resected surgically, interventional treatment can be performed. This is because the view of most scholars is that hepatocellular carcinoma that can be surgically resected should be surgically resected. However, many studies in the past have shown that interventional treatment for small hepatocellular carcinoma is very effective, and the five-year survival rate can reach more than 60%. For patients who can be surgically resected, because surgical resection is a radical treatment, most scholars believe that surgical resection should be preferred. Will metastatic liver cancer be treated by interventional therapy? Yes, the vast majority of our interventions in daily work are in patients with liver metastases, most commonly lung cancer, breast cancer and liver metastases from gastrointestinal tumors, in addition to female genital tumors and urinary tract tumors. These tumors are prone to liver metastasis, especially digestive tract tumors are prone to liver metastasis. Liver metastasis from digestive tract tumors and breast cancer is very effective with interventional treatment, which is better than systemic chemotherapy. What is the difference between interventional treatment and primary liver cancer? There is no difference in terms of technology, but there is a difference in terms of drugs. In terms of drug selection, it is based on the origin of the primary lesion, what kind of tumor is the original tumor, what drugs are used, and what drugs are still selected for metastasis to the liver. But there is no difference from the operation technique.
