目的

探讨超声造影定量灌注（Q-CEUS）分析评估术前肝细胞癌（肝癌）组织分化程度的可行性和应用价值。

方法

回顾性分析2015年1月至2016年6月在中山大学附属第一医院接受超声造影检查的91例肝癌患者临床资料。其中男78例，女13例；平均年龄（52±12）岁。患者均签署知情同意书，符合医学伦理学规定。对患者进行Q-CEUS灌注分析，检测峰值强度上升时间（RT）、达峰时间（TTP）等参数。RT、TTP与肝癌组织分化程度关系分析采用单因素方差分析，采用受试者工作特征（ROC）曲线评价灌注参数对肝癌组织分化程度的诊断价值。

结果

高、中、低分化肝癌患者分别为22、53和16例。Q-CEUS分析显示肿瘤和瘤内最高增强区（TER）的RT、TTP与分化程度相关，随分化程度降低而变小（F=21.374，10.575和14.629，17.432；P<0.05）。肿瘤和TER的RT、TTP在高、中分化组间差异有统计学意义（HSD-t=13.317，13.136和15.003，14.473；P<0.05），高、低分化组间差异亦有统计学意义（HSD-t=11.425，10.754和12.741，12.145；P<0.05）。肿瘤RT、TTP诊断高分化肝癌的ROC曲线下面积分别为0.835、0.696，TER的RT、TTP诊断高分化肝癌的ROC曲线下面积为0.805、0.783，且肿瘤RT的ROC曲线下面积明显大于肿瘤TTP（Z =2.855，P<0.05）。

结论

Q-CEUS灌注参数RT、RT可用于高分化肝癌的鉴别诊断，诊断价值中等，且RT的诊断价值优于TTP。

Objective

To explore the feasibility and application value of quantitative contrast-enhanced ultrasound perfusion (Q-CEUS) in the preoperative evaluation of differentiation degree of hepatocellular carcinoma (HCC).

Methods

Clinical data of 91 patients with HCC undergoing contrast-enhanced ultrasound in the First Affiliated Hospital of Sun Yat-sen University from January 2015 to June 2016 were retrospectively analyzed. Among them, 78 patients were male and 13 were female, with an average age of (52±12) years. The informed consents of all patients were obtained and the local ethical committee approval was received. Q-CEUS analysis was performed in all patients. Related data such as the rise time (RT) of peak intensity and time to peak (TTP) were recorded. The relationship among RT, TTP and the differentiation of HCC was analyzed by one-way ANOVA. The diagnostic value of perfusion parameters on the HCC differentiation was evaluated by receiver operating characteristic (ROC) curve.

Results

In total,22, 53 and 16 patients were respectively diagnosed with highly-, moderately- and lowly-differentiated HCC. Q-CEUS analysis indicated that RT and TTP in the tumor and tip-enhanced region (TER) were significantly correlated with the HCC differentiation, they decreased along with the decrease of differentiation degree (F=21.374, 10.575 and 14.629, 17.432; P<0.05). The RT and TTP in the tumor and TER significantly differed between the highly- and moderately-differentiated groups (HSD-t=13.317, 13.136 and 15.003, 14.473; P<0.05), and between the highly- and lowly-differentiated groups (HSD-t=11.425, 10.754 and 12.741, 12.145; P<0.05). The area under the ROC curve of RT and TTP in the tumor was respectively 0.835 and 0.696 for diagnosing highly-differentiated HCC, and was respectively 0.805 and 0.783 in TER. The area under the ROC curve of RT in the tumor was significantly larger than that of TTP (Z=2.855, P<0.05).

Conclusions

Q-CEUS parameters, such as RT and TTP, can be used in the differential diagnosis of highly-differentiated HCC with moderate diagnostic value. The diagnostic value of RT is better than that of TTP.
