HCC is a common disease worldwide [1]. Since HCC is associated with intrahepatic metastasis and multicentricity, recurrence is often a problem. Therefore, risk assessment of HCC recurrence is useful for selection of the treatment method and follow-up after treatment. A high α-fetoprotein (AFP) level, non-simple nodular (SN) type, multiple tumors and pathological microvascular invasion (MVI) have been identified as risk factors for early recurrence in surgical cases [2–5]. It was also reported that postoperative extrahepatic metastasis recurrence tends to occur more frequently in cases with portal invasion and advanced stage [6].

Preoperative PET-CT is useful for predicting recurrent extrahepatic metastasis of hepatocellular carcinoma after resection
