Abstract
BACKGROUND: This study aimed to determine whether patterns of tumor clonal origin in pluri-nodular hepatocellular carcinoma (PNHC) could serve as an indicator of tumor recurrence following liver transplantation.
MATERIAL AND METHODS: Tumor tissue samples from 60 PNHC patients who underwent liver transplantation were examined. The diagnosis of patients conformed to the University of California San Francisco (UCSF) standards for pluri-nodular hepatocellular carcinoma. We performed loss of heterozygosity tests at multiple microsatellite sites to determine the clonal origins of the tumors. Clinical information, pathological data, preoperative serum alpha-feto protein (AFP) and postoperative follow-ups were obtained and correlations between the clonal origin of the tumor, tumor-free survival, pathological characteristics, and AFP levels in serum were studied.
RESULTS: A total of 165 tumor nodules were collected. Tumor clonal origins were identified as intrahepatic metastasis (IM; 41.67%), multicentric occurrence (MO; 55%) or unidentified (3.33%). Three-year tumor-free survival for the IM group was 48% compared to 75.76% in the MO group (p<0.05), while the occurrence of microscopic tumor thrombus was 100% and 3.03% (p<0.05) for these groups, respectively. The degree of tumor differentiation was 80% for the IM group and 18.18% for the MO group (p<0.05), while the mean AFP concentration for these groups was 226.80 μg/L (2.78–3000 μg/L) and 24.59 μg/L (1.16–531. 30 μg/L; p<0.05), respectively.
CONCLUSIONS: Clonal origin patterns can serve as important indicators to predict the recurrence of PNHC following liver transplantation. Taken together with pathological characteristics and preoperative serum AFP levels, the risk of recurrence can be established in advance.
