摘要: 目的 研究超声造影(CEUS)技术诊断肝硬化结节(CN)癌变风险及微小肝细胞癌(sHCC)的应用价值。方法 选取收集2018年2月至2020年2月医院收治的127例肝硬化结节患者作为研究对象,随访记录127例病理结果。以超声引导穿刺病理活检结果为金标准,记录CN、低度增生不良结节(LGDN)、高度增生不良结节(HGDN)及sHCC。比较不同病理阶段患者CEUS特征,分析CEUS判断CN癌变病理类型和sHCC的准确性。结果 127例患者随访8~32个月,平均(16.6±5.4)个月。最后一次穿刺病理结果显示127例患者中,CN者38例,LGDN者32例,HGDN者26例,sHCC者31例。CN、LGDN、HGDN及sHCC组TTP分别为(44.6±13.2)s,(38.4±10.9)s,(30.5±9.0)s及(23.8±8.5)s,P<0.05;MTT分别为(141.0±35.4)s,(130.4±29.8)s,(117.3±30.2)s及(109.5±27.4)s,P<0.05;RT分别为(40.6±11.2)s,(35.4±7.7)s,(31.2±9.3)s及(22.1±8.7)s,P<0.05。CEUS检查显示CN灌注模式(Ⅳ期31例,Ⅴ期5例,Ⅵ期2例,Ⅶ期1例)、LGDN(Ⅴ期4例,Ⅵ期24例,Ⅶ期3例,Ⅷ期1例)、HGDN(Ⅵ期23例,Ⅶ期3例)及sHCC(Ⅰ期24例,Ⅱ期2例,Ⅲ期5例),各病理阶段患者CEUS灌注模式差异有统计学意义(P<0.05)。ROC分析结果显示TTP(AUC=0.642,95%CI=0.526~0.758)、MTT(AUC=0.651,95%CI=0.536~0.766)及RT(AUC=0.716,95%CI=0.606~0.826)对判断sHCC具有一定应用价值(P<0.05)。TTP、MTT及RT联合预测概率判断sHCC的AUC为0.802(SE=0.047,95%CI=0.710~0.895,P<0.05),敏感度为0.935,特异度为0.561。结论 CEUS能有效鉴别CN病理演变过程,CEUS检查有助于sHCC的早期检出。

Abstract: Objective To investigate the efficacy of contrast-enhanced ultrasound (CEUS) in diagnosing canceration nodules (CN) in cirrhotic liver and small hepatocellular carcinoma (sHCC). Methods One hundred and twenty-seven patients with liver cirrhotic nodules from February 2018 to February 2020 were included as the research objects. In all patients pathological evaluation of the liver nodules achieved by ultrasound-guided biopsy were recorded as the gold standard, including CN, low-grade dysplastic nodules (LGDN), high-grade dysplastic nodules (HGDN) and sHCC. The characteristics of CEUS in different pathological stages were compared. The accuracy of CEUS in judging the pathological type of CN canceration and sHCC were analyzed. Results The 127 patients were followed up for 8 to 32 months with an average period of time of (16.6±5.4) months. The liver biopsy results showed that there were 38 cases of CN, 32 cases of LGDN, 26 cases of HGDN and 31 cases of sHCC among the 127 patients. The time to peak (TTP)of CN, LGDN, HGDN and sHCC groups were (44.6±13.2)s, (38.4±10.9)s, (30.5±9.0)s and (23.8±8.5)s, respectively(P<0.05), the mean transit time (MTT) were (141.0±35.4)s, (130.4±29.8)s, (117.3±30.2)s and (109.5±27.4)s, P<0.05, the rise time (RT) were (40.6±11.2)s, (35.4±7.7)s, (31.2±9.3)s and (22.1±8.7)s, P<0.05. The CEUS examination showed that the CN perfusion mode (31 cases in stage IV, 5 cases in stage V, 2 cases in stage VI and 1 case in stage VII), LGDN (4 cases in stage V, 24 cases in stage VI, 3 cases in stage VII and 1 case in stage VIII), HGDN(23 cases in stage VI and 3 cases in stage VII), sHCC (24 cases in stage 1, 2 cases in stage II and 5 cases in stage III). The difference of CEUS perfusion mode were statistically significant in different pathological stages (P<0.05). The ROC analysis showed that the TTP (AUC=0.642, 95%CI=0.526~0.758), MTT (AUC=0.651, 95%CI=0.536~0.766) and RT (AUC=0.716, 95%CI=0.606~0.826) had certain application value in judging sHCC (P<0.05). The AUC of sHCC was 0.802 of joint prediction probability of TTP, MTT and RT (SE=0.047, 95%CI=0.710~0.895, P<0.05), the sensitivity was 0.935 and the specificity was 0.561. Conclusion The CEUS can effectively identify the pathological process of CN, and the CEUS examination is helpful for the early detection of sHCC.
