ABSTRACT

Objective To explore the expression of calcium binding protein (S100A11) and its clinical significances in human hepatocellular carcinoma (HCC) tissue and blood plasma. Methods The expressions of S100A11 in 46 cases of HCC tissues and their paracancerous tissues were detected by immunohistochemistry. The relationship between S100A11 expression level in HCC tissues and clinical parameters was analyzed. The S100A11 expression levels in blood plasma of HCC patients (62 cases), liver cirrhosis patients (32 cases), chronic hepatitis patients (30 cases) and healthy subjects (30 cases) were detected. The sensitivity and specificity of S100A11, alpha fetoprotein (AFP) and γ-glutamyl transpeptidase Ⅱ (GGT-Ⅱ ) in HCC diagnosis were compared. Results The positive rate of S100A11 in HCC tissue (78. 3%) was significantly higher than that in paracancerous tissues (19. 6%) (P<0. 05). The expression level was correlated with the degree of differentiation, the lower differentiation degree with the higher expression level. According to ROC curve, if the cutoff points for diagnosis was set at 7. 3 μg/L, the positive rate of S100A11 in HCC patients blood plasma was 30. 6% , which was significantly higher than that in the blood plasma of patients with liver cirrhosis, patients with chronic hepatitis and healthy persons (P<0. 05). There was no correlation between S100A11 and AFP or GGT-Ⅱ in the blood plasma of HCC patients. These three indicators were complementary in HCC diagnosis, and the diagnostic sensitivity increased to 84.5% with combined detection. Conclusions S100All may be related to HCC genesis and development. The HCC diagnostic sensitivity may be increased with combined detection of S100All ,AFP and GOT- Ⅱ.
