225 Association between the gynecologic imaging reporting and data system in adnexal masses and the type of specialist: gynecologist vs gynecologic oncologist

Introduction The Gynecologic Imaging Reporting and Data System (GI-RADS) is a reporting system that offers a management protocol for adnexal masses and suggests the requirement of patient remision to a gynecologic-oncologist. The aim was to determine if there is an association between GI-RADS score and the specialist that performs the surgery. Methods Ambispective study that included 547 patients that underwent preoperative ultrasound. A total of 605 adnexal masses were evaluated by ultrasound between 2012 and 2018 in one center. This masses were classified according to GI-RADS by gynecologic ultrasound experts. For the analysis, we grouped GI-RADS 1, 2 and 3 as benign masses, and GI-RADS 4 and 5 as malignant masses. We also identified the type of specialist that performed the surgery and classified them in 2 categories: gynecologist and gynecologic oncologist. A descriptive analysis of the patients and the masses found was conducted. Additionally, a Chi2 test was used in order to determine a possible association with a 95% confidence interval. Results The median of age of the patients was 41 (range, 32–51) years, 148 (27%) were postmenopausal. Of the 605 masses, 140 (23.1%) were classified as malignant. The morphological characteristics of malignant masses included: multilocular-solid, with papillae and vascularization. A statistically significant association between GI-RADS and the specialist, and GI-RADS and the histopathology was found (p Conclusion In our center, GI-RADS classification can be used as a tool to decide the need of remission of a patient to gynecologic oncology.
