Mj. Ballester et al., DIAGNOSIS OF ENDOMETRIAL CARCINOMA - PREDICTIVE VALUE OF TRANSVAGINALCOLOR DOPPLER, Journal of gynecologic surgery, 10(3), 1994, pp. 173-183
The objective of this study was to determine whether transvaginal ultr
asound plus color Doppler flow improve the ability to diagnose endomet
rial carcinoma and allow better discrimination between benign and mali
gnant endometrial lesions. One hundred thirty women with abnormal uter
ine bleeding were evaluated with transvaginal color Doppler before fra
ctional dilatation and curettage (D&C). The endometrial line thickness
and endometrical characteristics were evaluated by endosonography. Th
e resistive and pulsatile indices of the uterine arteries and of the e
ndometrium were evaluated with transvaginal color Doppler. Following D
&C and tissue diagnosis, women were divided into two groups, 62 with a
histologic diagnosis of endometrial adenocarcinoma and 68 with benign
endometrial tissue. All women with endometrial carcinoma underwent TA
H and BSO. A complete histopathologic study was done an all surgical s
pecimens. The International Federation of Gynecology and Obstetrics (F
IGO) stage and tissue grading were determined in all cases. The histop
athologic findings were correlated with ultrasound and transvaginal co
lor Doppler results. Patients with adenocarcinoma had an average endom
etrial thickness of 26.13 mm (range 8-87 mm). The average thickness fo
r functional endometrium (proliferative) was 10.5 mm (range 6-23 mm).
The was no case of carcinoma where the endometrial thickness was less
than 8 mm. Intraendometrial neovascularization was not observed in any
case with functional or atrophic endometrium. The flow indices in pat
ients with endometrial adenocarcinoma are significantly different from
the flow indices of patients with benign endometrial tissue. Transvag
inal color Doppler increases the sensitivity of endometrial malignancy
diagnosis. The method is capable of detecting important differences i
n flow indices and endometrial line characteristics between benign and
malignant endometrial tissue.
