    Abstract:
    Hepatocellular carcinoma (HCC) nodules newly found in the explant liver have been observed, but the impact on patient prognosis is not known. Sixty HCC patients who underwent living donor liver transplantation were the subjects of the study. Radiologic findings prior to transplantation and pathologic findings of the explant liver were compared. Histologic characteristics of preoperatively overlooked tumors were examined. The influence of the discrepancy between these findings on tumor recurrence was evaluated. A total of 227 HCC nodules were found in the explant livers. Of these, 91 nodules (40%) were newly found by pathologic examination. They were smaller and more likely to be well differentiated than the others. The number and size of the tumors were underestimated in 50% (30/60) and 32% (19/60), respectively. There was no significant difference in the recurrence-free survival rate between patients who met the Milan criteria both in the pre- and post-transplant evaluation (n = 29) and those who met the Milan criteria preoperatively, but exceeded the criteria in the explant (n = 19). Nodules newly found in the explant liver had little impact on recurrence-free survival. A decision for liver transplantation according to the Milan criteria based on preoperative evaluation is valuable for securing an excellent outcome.
