Objective:

To evaluate the influencing factors and diagnostic accuracy of transvaginal color Doppler sonography (TV-CDS) in judging the myometrial invasion of endometrial carcinoma.

Methods:

The data of 209 pathologically defined endometrial cancer cases were reviewed. The preoperative TV-CDS results were compared with the postoperative histopathological findings. Then the effects of pathological category

uterine size and patient age on the diagnostic accuracy of TV-CDS were analyzed.

Results:

Pathologic examination showed that 31 cases had no myometrial invasion

134 cases had superficial myometrial invasion

and 44 cases had deep invasion. The accuracy of TV-CDS in diagnosing deep myometrial invasion of endometrial carci

noma was 77.51%. There were no significant differences in pathological category

uterine size and patient age between accurate diagnosis group and misdiagnosis group (

P

0.05).

Conclusion:

TV-CDS has diagnostic value in judging myometrial invasion of endometrial cancer. The pathological category

uterine size and patient age have no significant influences on the diagnostic accuracy of TV-CDS.
