RESUMO
<p><b>OBJECTIVE</b>To investigate the expression of special AT-rich sequence binding protein 1 (SATB1) mRNA in hepatocellular carcinoma (HCC) and explore its correlation to the clinicopathological features, surgical outcomes and metastasis of HCC.</p><p><b>METHODS</b>The total RNA was extracted from 102 HCC tissues and the adjacent tissues, and the expression of SATB1 mRNA was detected using quantitative real-time PCR. The correlations of SATB1 mRNA expression to the clinicopathological features, postoperative recurrence and metastasis of the tumor were analyzed.</p><p><b>RESULTS</b>The expression of SATB1 mRNA in HCC tissues was 3.27 folds higher than that in the adjacent tissues (P<0.001). The expression of SATB1 mRNA in HCC was associated with liver cirrhosis, AFP level, tumor size, tumor thrombi, histological differentiation, TNM classification, postoperative recurrence and metastasis (P<0.05), but not to the patients' gender, age, HbsAg positivity, HCV-Ab positivity, tumor number, or the presence of tumor encapsulation (P>0.05). In patients with significant high expression, high expression, and low expression of SATB1 mRNA, the postoperative recurrence rates were 82.68%, 0, and 0, with the 3-year survival rate of 0, 52.63%, and 100%, respectively.</p><p><b>CONCLUSION</b>SATB1 mRNA expression is associated with the postoperative recurrence and metastasis of HCC, and can be used as an indicator for predicting the recurrence and metastasis of HCC.</p>
