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

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

P

＜0.05)

and the specificity was not significantly different (

P

＞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.
