Abstract

Objective: To prospectively evaluate the accuracy of a multiparameter, ultrasound-based triage and its impact on surgical management of adnexal masses. Methods: Masses evaluated as normal according to Ferrazzi's sonographic morphological score were considered as being at low risk of malignancy and eligible for laparoscopic treatment without further evaluation. Masses evaluated as abnormal, but without additional risk factors such as ascites, diameter ≤ 10 cm, bilaterality, immobility, resistance index ≥ 0.6 and serum CA 125 <35 IU/mL were considered at moderate risk and eligible for laparoscopic evaluation and treatment. Masses with abnormal morphological score and any of these additional risk factors were considered at high risk and treated by laparotomy. The results of pathological examination were obtained for each mass. Results: Two hundred and four (87%) masses were benign and 30 (13%) were malignant. Among 182 low-risk, 19 moderate-risk and 33 high-risk masses, the odds of malignancy were 1:90, 1:18 and 4.5:1, respectively. To calculate the diagnostic accuracy of this algorithm, low- and moderate-risk groups were considered together: the sensitivity was 90%, specificity 97%, positive predictive value 82% and negative predictive value 99%. The new algorithm was significantly more accurate than was morphological score alone (P = 0.0002). Ninety-six percent of benign masses were treated by laparoscopy. All three patients with malignant masses that were incorrectly assigned to laparoscopy underwent laparoscopic adnexectomy and frozen section. Conclusions: The accuracy of this new algorithm was higher than that of the sonographic morphological scoring system alone. In the present series, it allowed the treatment by laparoscopy of 96% of benign adnexal masses without mismanagement of any cases of ovarian cancer.
