The treatment of postoperative recurrence of liver cancer should be combined with the patient's general condition, liver function, tumor size, location, whether there is distant metastasis and economic conditions to determine the specific individualized treatment program. Surgical resection, interventional therapy, radiofrequency ablation and administration of antineoplastic drugs such as sorafenib can also be carried out. Chinese patent medicine treatment, such as Huaier Granules, can also be considered for immunomodulation treatment. In short, it is a comprehensive treatment and individual treatment. Liver cancer is a kind of tumor with a high recurrence rate. Even if it is completely resected by surgery, it also needs regular reexamination of alpha fetoprotein and liver color ultrasound. If necessary, liver CT and liver MRI should be performed. Evaluate the change of the condition and whether it occurs in the recurrence of the tumor, and actively deal with it once it occurs.
