Expression and prognostic significance of CIP2A mRNA in hepatocellular carcinoma and nontumoral liver tissues

Biomarkers. 2012 Aug;17(5):422-9. doi: 10.3109/1354750X.2012.680608. Epub 2012 Apr 27.

Abstract

Objective: This study was undertaken to determine the role of cancerous inhibitor of protein phosphatase 2A (CIP2A) in predicting prognosis of hepatocellular carcinoma (HCC).

Methods: CIP2A mRNA level of 136 pairs of tumor and nontumoral liver tissues of HCC patients after hepatectomy were investigated by quantitative real-time reverse transcription polymerase chain reaction.

Results: Intratumoral CIP2A mRNA was not associated with patients' prognosis. However, nontumoral CIP2A mRNA, which was correlated with lack of tumor encapsulation, poor tumor differentiation, intrahepatic metastasis, and high tumor-node-metastasis stage was an independent risk factor for overall survival and recurrence-free survival.

Conclusions: Nontumoral CIP2A mRNA expression might serve as a novel biomarker for HCC patients undergoing resection.
