Abstract
AIM: To compare the significance of real-time tissue elastography and serological indexes with liver biopsy in liver fibrosis staging and diagnosis.
METHODS: Seventy-six hospitalized patients with liver fibrosis treated at the Second Affiliated Hospital of Kunming Medical University from March 2011 to February 2012 were included. All patients underwent the liver biopsy, real-time tissue elastography to quantify the degree of liver fibrosis, and measurement of serological indexes including hyaluronic acid (HA), collagen type Ⅳ (CⅣ), type Ⅲ procollagen (PCⅢ), laminin (LN), transforming growth factor-β1 (TGF-β1), and platelet derived growth factor (PDGF). The diagnostic accuracy of real-time tissue elastography and serological indexes was compared with that of liver biopsy.
RESULTS: The LF value of real-time tissue elastography, serological indexes and liver biopsy had significant differences in the staging of hepatic fibrosis (P < 0.05). All the values gradually increased with the degree of liver fibrosis. Significant correlations were noted between different methods (P < 0.05). When LF was 3.1 or less, liver fibrosis stage was mainly S1; when LF was > 3.1, liver fibrosis stage was mainly S2, 3 and 4. When HA, LN, CIV, PCⅢ, PDGF and TGF-β1 were equal to or lower than 66.5, 70.5, 59, 116.6, 28.3, and 665.4, respectively, liver fibrosis stage was mainly S1; when HA, LN, CIV, PCⅢ, PDGF and TGF-β1 were > 66.5, 70.5, 59, 116.6, 28.3, and 665.4, respectively, liver fibrosis stage was mainly S2, 3 and 4. The area under the ROC curve was > 0.9 for LF, between 0.7 and 0.9 for HA and PCⅢ, and between 0.5 and 0.7 for LN, CIV, PDGF and TGF-β1.
CONCLUSION: Real-time tissue elastography findings are positively correlated with the degree of liver fibrosis. Serological indexes of HA, LN, CIV, PCⅢ, PDGF and TGF-β1 increase with the increase of degree of hepatic fibrosis, and can be used to indirectly assess the degree of liver fibrosis. LF has high accuracy in the diagnosis of liver fibrosis, HA and PCⅢ have medium accuracy, and LN, CIV, PDGF and TGF-β1 have low accuracy. Real-time tissue elastography findings are coincident with the pathological results and can be used to assess the degree of liver fibrosis.
