摘要: 目的 探索乙型肝炎病毒(hepatitis B virus,HBV)相关肝硬化结节癌变磁共振(magnetic resonance,MR)动态增强特征与免疫组织化学标志物磷脂酰肌醇蛋白聚糖-3(glypican-3,GPC-3)及CD34表达量之间的对应关系。方法 收集44个乙型肝炎(以下简称乙肝)肝硬化患者中经病理证实的47个肝硬化结节纳入本研究,术前均行MR扫描,用软件将动态增强扫描序列自动生成时间-信号曲线,术后常规病理及免疫组织化学染色,观察GPC-3和CD34表达。结果 1)在47个结节中,GPC-3在早期肝癌(early hepatocellular carcinoma,eHCC),高级不典型增生结节(high grade dysplastic nodule,HGDN),低级不典型增生结节(low grade dysplastic nodule,LGDN)各组中的阳性率分别为78.9%、26.1%、0%,CD34强阳性表达在eHCC、HGDN及LGDN中分别为78.9%、56.5%、0%,差异均有统计学意义(P<0.05)。2)eHCC、HGDN、LGDN的MR动态灌注时间-信号曲线特点分别倾向为陡升型、缓升型、平行型。GPC-3阳性的结节和阴性的结节两者之间时间信号曲线差异有统计学意义(P<0.05)。CD34强阳性、弱阳性、阴性的eHCC之间时间-信号曲线差异有统计学意义(P<0.05)。结论 1)MR时间-信号曲线特点对eHCC及HGDN的鉴别诊断有一定的价值。2)GPC-3表达阳性具有提示结节良恶性的诊断价值,同时MR时间-信号曲线表现为陡升型。3)CD34表达量与MR增强时间-信号曲线呈正相关。

Abstract: Objective To study the correlation between MR(magnetic resonance) enhancement features and GPC-3 (glypican-3) and CD34 expression in hepatic B Virus (HBV)-related liver cirrhosis nodules. Methods This retrospective study collected 47 pathology proven nodules in 44 HBV-related liver cirrhosis patients, who underwent MRI and made the time-signal curve of dynamic enhancement, and we also evaluated the immunohistochemical biomarkers levels of GPC-3 and CD34. Results 1) In the 47 nodules, GPC-3 positive rate in early hepatocellular carcinoma (eHCC), high grade dysplastic nodule (HGDN), low grade dysplastic nodule(LGDN) were 78.9%, 26.1% and 0%, respectively (P=0.000), CD34 positive rates were respectively 78.9%, 56.5%, 0%, and the difference was statistically significant (P=0.005). 2) The MR time-signal features at different stage of nodules, GPC-3 positive and negative nodules, CD34 strongly positive and weakly positive and negative nodules, were statistically significant(P<0.05). Conclusion 1) MR time-signal curve has a certain differential diagnostic value for early stage of HCC. 2) GPC-3 is a highly specific biomarker for the malignance, while MR time-signal curve inclined to show rapid rise type. 3) CD34 expression was positively correlated with MR time-signal curve.
