Reduced clinical manifestations: patients’ original symptoms such as pain in liver area and fatigue can be reduced, and appetite can be increased. At the same time, the degree of jaundice will decrease. 2. Improvement of imaging results: if there is an effect after interventional therapy, it can be found that the volume of the original liver cancer lesion of the patient is reduced in CT examination. 3. Improvement of laboratory test results: after the improvement of interventional therapy, the level of laboratory tests such as tumor indexes can be decreased, for example, the level of alpha-fetoprotein can be decreased.
