Here, we present the clinical features of patients who developed delayed HCC recurrence after LT.Patients and Methods: We reviewed the data of eligible patients from February 1999 to December 2020 from medical records.Results: From among 195 (17%) HCC patients who received LT, 34 experienced HCC recurrence, with 5 (15%) delayed recurrence. These five explant tumors were staged T1b–T2, graded II–III, with two vascular invasion and four beyond the Milan criteria. The median time to recurrence was 6.1 years, with the longest interval being nearly 18 years. Recurrence patterns included two extrahepatic, one intrahepatic, and two mixed extrahepatic and intrahepatic recurrences. A drastic increase in serum alpha-fetoprotein levels was observed in four cases 1 year before recurrence. Management of recurrence included locoregional (surgssical resection in three, radiotherapy in three, transarterial chemoembolization in one, radiofrequency ablation in one) and systemic sorafenib use in three. Two patients died within 12– 18 months, one died within 18– 24 months, and two are still alive until the end of the study, with respective 13.5- and 16.5-month survival.Conclusion: Delayed HCC recurrence could occur over 10 years. Therefore, continual surveillance for recurrence is justified, but biomarkers and intervals or intensities specific for delayed recurrence are not validated, which warrants further validation to facilitate personalized medical care.Keywords: liver transplantation, hepatocellular carcinoma, recurrence, survival, case series
