Surgery: mainly for larger metastatic tumors, local resection through surgery can reduce compression and neurological symptoms. 2. Radiotherapy: through local radiotherapy, it can kill the tumor cells, promote the shrinkage of tumor cells and slow down the progress of lesions. 3. Chemotherapy: when brain metastasis of liver cancer occurs, regular application of chemotherapy drugs is needed to control it, commonly used drugs include cisplatin, fluorouracil and so on. 4. Symptomatic treatment: if there is increased intracranial pressure, mannitol can be applied to lower the cranial pressure; some patients will have epileptic symptoms, sodium valproate can be applied. The appearance of the brain metastasis accompanied by obvious headache, dizziness, vomiting and other symptoms, the need for timely medical observation, standardized treatment under the guidance of clinicians.
