The efficacy can be determined by tumor markers and imaging examination after liver cancer intervention. 1. Review tumor marker, if there is elevation of alpha-fetoprotein or abnormal prothrombin, if it gradually decreases after intervention, it suggests that the effect is relatively good, but attention should be paid to exclude other possible causes of elevation of alpha-fetoprotein. 2. Imaging examination, which is the main method to evaluate the efficacy. If the tumor shrinks or even disappears, the necrotic area of the tumor increases, and the enhancement of the tumor is not obvious or the area of enhancement decreases in enhanced CT or enhanced MRI, it suggests that the treatment is effective. Generally speaking, if the lesion can no longer increase in size, reduce the load of the tumor, restore the function of the liver, and improve the quality of life of the patient, it can be considered that the therapeutic effect has been achieved, and it is recommended that the patient should follow the doctor’s instructions and undergo regular rechecks.
