Abstract

The purpose of this study was to investigate the potential of the blood levels of MIR-21 and PTEN as novel biomarkers for oral squamous cell carcinoma (OSCC). We initially detected MIR-21 and PTEN using real-time RT-PCR from 90 blood samples and then compared their results with expression in cancer tissues from 10 OSCC patients. Finally, we examined the relationship between these markers and clinical parameters. Blood MIR-21 and PTEN had significant diagnostic value for OSCC and, to an extent, correlated with the expression level of tumour MIR-21 and PTEN. In addition, they were associated with differentiation and nodal status. Thus circulating MIR-21 and PTEN might represent new complementary tumour markers for OSCC.

Keywords: Circulating biomarkers; MIR-21; OSCC; PTEN.
