OP29.09: Accuracy and reproducibility of ultrasonography for the diagnosis of ovarian cancer in operators with different degrees of experience

Abstract

according to the IOTA protocol. A proper counselling on a low ovarian cancer risk was given and an adequate informed consent was obtained. Sonographic follow-up was proposed at 3 and 9 months, than yearly. Surgery was proposed in case of changes of ovarian cyst volume (>50%) and/or sonographic parameters at TVS-CD. Demographic, medical, sonographic and pathologic data were recorded. Results: 98 post-menopausal patients with 106 ovarian cysts were enrolled. Median age (IR) was 69 years (59–74). Median years after menopause (IR) were 18 (8–24). Median BMI (IR) was 26 kg/m2 (24–29). Mean parity (±sd) was 2 ± 1.8 women reported bilateral cysts. 53 cysts were unilocular, 53 multilocular. Median cyst diameter (IR) of unilocular and multilocular ovarian cysts was 50 mm (34–56). At a median follow-up period of 36 months, surgery was performed in 28 cases: 14 patients required immediate removal, 5 drop-out, 9 volume changes. One successfully managed cardiac arrest occurred during laparoscopic procedure. No malignant lesions were reported at histology. Conclusions: Sonographic follow-up might be a useful option in the clinical management of incidental unilocular >5 cm and multilocular <7 cm ovarian cysts in post-menopausal women. Larger and longer multicentres studies with strict sonographic parameters are needed to support this potentially safe conservative management.
