Median follow\u2010up was 4.6\u2009years (IQR 2.3\u20138.5). The tumor, which was deemed radiologically resectable before surgery, was found pathologically unresectable in two LT patients: viable tumor microembolism at sites where the tumor was present at diagnosis in one patient and severe tumor ossification close to the major vascular system in one patient. Four patients with tumor thrombus, unresectable radiologically, were pathologically resectable using LR with extracorporeal circulation. Among the four patients undergoing LR, two patients eventually received LT. One had a recurrence at the initial tumor site, and the other developed cirrhosis post\u2010LR. Surgical complications occurred in three LT patients and one LR patient. No complications related to long\u2010term immunosuppression have been observed in LT patients. However, one LT patient developed portal hypertension due to chronic rejection and is awaiting a deceased donor LT. One LT patient died due to recurrence.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n
