ABSTRACT
Primary liver cancer is the sixth most commonly diagnosed cancer and was the third leading cause of cancer deaths worldwide in 2020. It includes hepatocellular carcinoma (HCC) (representing 75%-85% of cases), intrahepatic cholangiocarcinoma (representing 10%-15% of cases), and other rare types. The survival rate of patients with HCC has risen with improved surgical technology and perioperative management in recent years; however, high tumor recurrence rates continue to limit long-term survival, even after radical surgical resection (exceeding 50% recurrence). For resectable recurrent liver cancer, surgical removal [either salvage liver transplantation (SLT) or repeat hepatic resection] remains the most effective therapy that is potentially curative for recurrent HCC. Thus, here, we introduce surgical treatment for recurrent HCC. Areas Covered: A literature search was performed for recurrent HCC using Medline and PubMed up to August 2022. Expert commentary: In general, long-term survival after the re-resection of recurrent liver cancer is usually beneficial. SLT has equivalent outcomes to primary liver transplantation for unresectable recurrent illness in a selected group of patients; however, SLT is constrained by the supply of liver grafts. SLT seems to be inferior to repeat liver resection when considering operative and postoperative results but has the major advantage of disease-free survival. When considering the similar overall survival rate and the current situation of donor shortages, repeat liver resection remains an important option for recurrent HCC.
