Intervention for recurrence of liver cancer after surgery is generally incurable because there is no radical cure for liver cancer at present. Liver cancer itself is a disease that cannot be completely cured, and interventional therapy is also carried out when surgery cannot be done. If it is in early stage, clinical cure may be achieved after timely surgery, while the chance of cure will be greatly reduced if interventional therapy is adopted when surgery cannot be performed. The main purpose of interventional therapy for recurrence of liver cancer after surgery is to prolong the survival time of patients, alleviate the related symptoms and improve the quality of life of patients, but it cannot completely cure liver cancer. Generally speaking, the 5-year survival rate can reach 10% after interventional therapy in early stage. If the cancer cells have metastasized to the distal part of the liver, the interventional therapy should be combined with other treatments to prolong the survival time of the patients, including targeted therapy, radiotherapy, chemotherapy, etc., in order to inhibit the cancer cells, and the specific treatments should be prescribed by the doctor. Patients with postoperative recurrence of liver cancer should also pay attention to diet, try to be light and nutritious, and prohibit spicy and stimulating food.
