摘要

目的：

评估高分辨率经阴道超声（transvaginal ultrasonography，TVS）在宫颈癌宫旁浸润诊断中的临床价值。

方法：

根据国际妇产科联合会（Federation International of Gynecology and Obstetrics，FIGO）的分期标准，对纳入研究的47例宫颈癌患者进行分期，在治疗前对所有患者行TVS和计算机体层成像（computed tomography，CT）检查，检查结果与手术后病理学检查结果进行比较，计算两种检查方法诊断的灵敏度、特异度、准确度、阳性预测值和阴性预测值，使用统计学方法分析两种方法的优劣。

结果：

按照FIGO分期标准常规划分后，47例宫颈癌患者中，ⅡA期及之前患者为24例，ⅡB期及之后患者为23例。CT诊断宫旁浸润的灵敏度、特异度、准确度、阳性预测值、阴性预测值分别为42.1%、64.3%、55.3%、44.4%、62.1%；TVS诊断结果的灵敏度、特异度、准确度、阳性预测值、阴性预测值分别为89.5%、82.1%、85.1%、77.3%、92.0%。TVS对宫旁浸润的诊断相较于CT其灵敏度、准确度、阳性预测值和阴性预测值更高（

均＜0.05），两者特异度差异无统计学意义（

＞0.05）。

结论：

TVS对宫颈癌宫旁浸润的诊断相较于CT其灵敏度、准确度、阳性预测值和阴性预测值更高，在临床中应多加运用TVS代替CT。

Abstract

Objective:

To evaluate the clinical value of transvaginal sonography (TVS) in the detection of parametrial invasion of cervical cancer.

Methods:

According to the standards of the Federation International of Gynecology and Obstetrics (FIGO)

47 patients included in this study were staged for cervical cancer

and all patients were diagnosed with TVS imaging and com

puted tomography (CT) before treatment. Compared with the histopathological results after surgery

calculated the sensitivity

specificity

accuracy

positive predictive value and negative predictive value of the two methods

and used statistical methods to analyze the pros and cons of the two methods.

Results:

According to the routine division of FIGO

there are 24 patients with stage ⅡA and below ⅡA

and 23 patients with stage ⅡB and above ⅡB. The sensitivity

specificity

accuracy

positive predictive value

negative predictive value of CT were 42.1%

64.3%

55.3%

44.4%

and 62.1%; the sensitivity

specificity

accuracy

positive predictive value

negative predictive value of TVS were 89.5%

82.1 %

85.1%

77.3%

92.0%. Compared with CT

TVS had higher sensitivity

accuracy

positive predictive value and negative predictive value in the diagnosis of cervical cancer parametrial invasion (all

＜0.05)

and the specificity was not significantly different (

＞0.05).

Conclusion:

TVS imaging has higher sensitivity

accuracy and positive predictive value in the diagnosis of parametrial invasion in cervical cancer than CT. TVS imaging should be used instead of CT in clinical practice.
