Simple Risk Score for Prediction of Early Recurrence of Hepatocellular Carcinoma within the Milan Criteria after Orthotopic Liver Transplantation.

ABSTRACT: Ten to twenty percent of the hepatocellular carcinoma (HCC) patients fulfilling the Milan criteria (MC) recurred within three years after orthotopic liver transplantation (OLT). We therefore utilize a training cohort to develop an improved prognostic model for predicting the recurrence in these patients. By univariate and multivariate analysis, AFP level [cut-off value: 321?ng/mL, area under the curve (AUC)?=?0.724, 95% confidence interval (CI)?=?0.604-0.843, P?

Project description:Introduction: Several attempts have been made to expand the indications of liver transplantation for hepatocellular carcinoma (HCC) beyond Milan criteria. We aimed to define genomic features that enable the identification of patients with HCC beyond Milan criteria who have acceptable transplant outcomes. Methods: Among 770 consecutive HCC patients transplanted at Mount Sinai Hospital and Mayo Clinic between 1990 and 2013, 132 had tumors exceeding Milan criteria on pathology and were enrolled in the study. Explant tumors were analyzed to assess genomic signatures of poor prognosis and immunohistochemical markers associated with tumor recurrence and overall survival. Results: Most of the patients were males (80%) and HCV positive (71%) with a median age of 56. HCC beyond Milan criteria was defined pre-operative in 67%. On pathology, 44% of the patients satisfied the ‘up-to-7 rule’. At a median follow-up of 88 months, 64 patients had died and 45 recurred; the 5-year overall survival (OS) and recurrence rates were 57% and 35%, respectively. CK19 gene signature was independently associated with recurrence (HR=2.95, p<0.001), along with tumor size >5 cm (HR=3.37, p=0.023) and presence of satellite lesions (HR=2.98, p=0.001). S2 subclass signature, which is known to be associated with progenitor cell markers, was independently associated with poor OS (HR=3.18, p=0.001), along with tumor size >5 cm (HR=5.06, p<0.001) and outside up-to-seven rule (HR=2.50, p=0.002). Using the presence of markers of progenitor cells (either CK19 or S2 subclass signatures) patients may be classified into poor-prognosis (n=58; 5-year recurrence 53%, survival 45%) and good-prognosis subgroups (n=74; 5-year recurrence 19%, survival 67%) (HR=3.16, p<0.001 for recurrence, and HR=1.72, p=0.04 for OS). Conclusion: Gene signatures associated with progenitor cell markers (CK19 and S2 subclass signatures) define outcome of HCC patients beyond Milan criteria after transplantation. Patients without these signatures achieve survival rates similar as those patients within Milan criteria. Once prospectively validated, these markers may provide the rationale for a limited expansion of liver transplantation indications.
