    Abstract:
    OBJECTIVE: In this study we compared the potential roles of preoperative human-telomerase reverse transcriptase (h-TERT) mRNA versus alpha-fetoprotein (AFP) mRNA expression in the peripheral blood as a tool to predict prognosis and tumor recurrence after living donor liver transplantation (LDLT) in hepatocellular carcinoma (HCC) patients. PATIENTS AND METHODS: We examined 14 patients with unresectable HCC who underwent LDLT. Six patients displayed stage IVA HCC that deviated from the Milan criteria, while the rest of the patients fell within the limitations of the Milan criteria. We analyzed the relationship between preoperative h-TERT mRNA or AFP mRNA expression in the peripheral blood and survival without recurrence. RESULTS: There was no significant difference between the survival curves without recurrence of those patients who did versus did not meet the Milan criteria. There was also no significant difference between the survival curves without recurrence among patients with positive versus negative AFP mRNA expression. However, there was a significant difference (P = .005) between the survival curves without recurrence of those patients with positive preoperative h-TERT mRNA expression versus those who either had an initially negative preoperative h-TERT mRNA or who converted from positive to negative after neoadjuvant immunochemotherapy. CONCLUSIONS: h-TERT mRNA seemed to prove more valuable than AFP mRNA not only to assess preoperative treatment modalities and postoperative patient surveillance, but also to evaluate prospective LDLT patients with HCC. Moreover, use of h-TERT mRNA could potentially expand the indications for transplantation to patients outside the Milan criteria.
