The size of response after liver cancer intervention has nothing to do with the specific treatment efficacy, and it is not that the bigger the response is the better, as each patient’s physique is different and has different response to intervention. Intervention of liver cancer is a palliative treatment for patients with middle or late stage, which is a method of inserting a special catheter into a specific area of liver for treatment through imaging means. At present, the common reactions after intervention include: pain in liver area, infection symptoms, nausea and vomiting in some patients, and further liver function abnormality in severe cases, and the adverse reactions usually last for more than one week. After liver cancer intervention, active liver-protecting, anti-inflammatory and anti-infection treatments are needed. After liver cancer intervention, it is necessary to monitor the patient’s status regularly, and if any uncomfortable symptoms are found, it is necessary to consult a doctor in time to improve the relevant examination and treat actively under the doctor’s guidance.
