Epithelial carcinoma of the ovary is a gynecological malignancy associated with high mortality
rate due to diagnosis in advanced stages, which occurs in more than 75% of the cases.
Recent strategies in reducing mortality have been studied, however screening tests have not
demonstrated to help in the diagnosis at early stages. Subjective impression of the examiner
using transvaginal ultrasound is considered the best method to discriminate between benign
and malignant adnexal tumors. The International Ovarian Tumor Analysis Group (IOTA) based
on ultrasound features of the adnexal masses, has developed robust rules and prediction
models that can be used by different examiners in various clinical settings.In Chile during
2012, national guidelines about epithelial ovarian cancer were published, establishing referral
and management criteria. Little mention about ultrasound exam was included: all “solid
tumors or complex adnexal masses” are sonographic criteria to refer patients to gynecologic
oncology units. Considering that many functional or benign pathologies can be classified as
“complex tumors”, it is important to use validated prediction models to improve accuracy of
ultrasonography and therefore optimize the referral to gynecological oncologists and avoid
surgeries of misclassified adnexal pathologies.
