Introduction Primary liver cancer is a significant health issue in China,where it ranks fourth in morbidity and second in mortality among all malignant tumors.[1-4]The 5-year overall survival rate of Chinese patients with liver cancer from 2012 to 2015 was only 12.2%for males and 13.1%for females.[5]Hepatocellular carcinoma(HCC)accounts for 75-85%of primary liver cancers.[6]Furthermore,most liver cancers are unresectable at diagnosis.To combat this,conversion therapy is used,which involves systematic treatments like anti-angiogenic drugs or molecular targeted therapy combined with immunotherapies,as well as locoregional treatments such as transcatheter arterial chemoembolization(TACE),hepatic artery infusion chemotherapy(HAIC),ablation therapy,and radiation therapy.The goal is to eliminate unresectable status and increase the chances of surgery.The reported 5-year survival rate after salvage surgery following tumor downstaging varied from 24.9-57%.
