Several screening procedures have been proposed to detect ovarian and endometrial cancer. However, none of them is sensitive and specific enough to be used in population-based screening programs. During our 5 year long study, 5013 asymptomatic women (44% premenopausal and 56% postmenopausal women) were scanned by transvaginal color and pulsed Doppler ultrasonography in an attempt to detect malignancy. These women had 404 adnexal cysts; 70 had resolved spontaneously on follow-up scans and 18 persisted. Another 316 sonographically benign cysts are still in the procedure of follow-up second scans. Of 5013 women, four women had stage I ovarian carcinoma and six had stage I endometrial carcinoma. There was one false-positive case encountered with an endometrioma. Only 14 women were subjected to major operative intervention; others underwent minor procedures based on the benign scan findings. No medical or surgical complications were reported. Transvaginal color Doppler ultrasonography, a noninvasive procedure, can detect ovarian and endometrial carcinoma in asymptomatic women and may be used as a screening procedure for these diseases.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
