METHODS: Levels of liver ANXA2 gene transcription or protein expression were analyzed in HCC-, their self- controlled precancerous-, and distant cancerous- tissues from 30 HCC. Serum levels of ANXA2 expression in 115 patients with HCC, 25 with metastatic liver can cer, 35 with chronic hepatitis, 28 with acute hepatitis, 38 with cirrhosis, and 30 healthy controls were deter- mined. Clinicopathological characteristics of circulating ANXA2 expression were analyzed, and its diagnostic efficiency and clinical values in HCC were evaluated. RESULTS: ANXA2 expression was localized in both cell membrane and cytoplasm in HCC tissue, mainly in the cytoplasm of matched adjacent cancerous tissue, and there was almost no positive staining in matched distant cancerous tissue. Abnormal expression of liver ANXA2 was present in HCC tissues compared with self-con- trolled adjacent- and distant-cancerous tissues at pro- tein or mRNA level. Circulating ANXA2 in HCC patients was significantly higher than that of other liver diseases (P 〈 0.01) except metastatic liver cancer. If the diag- nostic cutoff value of ANXA2 level was more than 18 ng/ mL, the incidence of serum ANXA2 was 86.96% in the HCC group, 80% in the metastatic liver cancer group, 31.58% in the liver cirrhosis group, none in the chronic hepatitis or acute hepatitis or normal control group, respectively. Serum ANXA2 expression in HCC patients was correlated with HBV infection (27.38 ± 5.67 ng/mL vs 18.58 ± 7.83 ng/mL, P 〈 0.01), extrahepatic metas- tasis (26.11±5.43 ng/mL ys 22.79 ± 5.64 ng/mL, P 〈 0.01), and portal vein thrombus (26.03 ± 5.99 ng/mL vs 23.06 ± 5.03 ng/mL, P 〈 0.01), and was significantly higher (P 〈 0.01) in the moderately- (26.19±5.34 ng/ mL) or the poorly- differentiated group (27.05 ± 5.13 展开更多
