Intervention in the middle stage of liver cancer is incurable and the clinical cure rate is relatively low. The development of liver cancer to intermediate stage indicates that the condition is more serious, and the cancer cells may have already metastasized or spread to the surrounding tissues and organs, such as lymph nodes, bones, blood, etc. At this time, the difficulty of treatment will rise significantly, and it is not possible to cure it completely, and according to the current analysis, the clinical cure rate is also relatively low. However, at present, when liver cancer develops to the middle stage, choosing interventional therapy can effectively improve the survival rate of patients, and the survival rate can reach 70% within 5 years, and the survival rate will be even higher if the patients have a good mentality and are able to be treated early. If interventional therapy is ineffective in the middle stage of liver cancer, it should be combined with other ways that can inhibit cancer cells to control the condition, such as radiotherapy, chemotherapy, immunotherapy, targeted therapy, etc., which can prolong the survival time and improve the quality of life.
