Objective: To assess the validity of transvaginal color Doppler how in
the prediction of malignancy in the uterine cervix, Study Design: Six
teen women with cervical pathology (14 with invasive carcinoma and 2 w
ith cervical intraepithelial neoplasia III) were examined using transv
aginal sonography as well as transvaginal color Doppler with measureme
nts of the resistance index of tumor blood flow. Twenty-four women wit
h histologically proven normal cervices served as a control group. Res
ults: Resistence index (RI) was significantly lower in the study group
[0.493; 0.475-0.511 (mean + 95% CI)] than in the control group [0.643
; 0.627-0.659] (P < 0.0001) (t'). There was no statistically significa
nt difference between the carcinoma group and the CIN III cases (P = 0
.067) (t'). Only two cases with cervical carcinoma showed dense vascul
arity with color Doppler. A RI cutoff less than or equal to 0.573 show
ed a sensitivity of 81% with a specificity of 93%, a positive predicti
ve value of 93%, and a negative predictive value of 81%. Conclusions:
Color Doppler flow evaluation of RI in cervis vessels may aid in the e
arly diagnosis and management of cervical carcinoma and in differentia
ting benign from malignant tumors, The validity of this technique as a
screening program for diagnosis is limited. (C) 1996 Academic Press,
