Abstract
Ovarian cancer is one of the most common gynecologic cancers that rank third after cervical and uterine cancer. It also has the worst prognosis and the highest mortality rate.
The frequency of this cancer varies according to countries and ethnicity.
Ovarian tumors are divided in epithelial, representing almost 90% of cases, germ cell (3%), and sex cord-stromal (2%).
Ovarian cancer continues to be diagnosed at advanced stage with high fatality rates. A significant contributing factor is lack of clear alarm symptoms.
There is a strong rationale for ovarian cancer screening because detection of asymptomatic preclinical disease at an earlier stage could reduce mortality by 10-30%.
The Aim of this study is to compare between the ADNEX model and the RMI as a screening model in cases with postmenopausal ovarian cysts.
A prospective observational cross-section diagnostic test accuracy study was conducted in Ain Shams University Maternity Hospital, faculty of medicine.
