New sonographic morphology score for the differentiation of malignant from benign ovarian tumors

Combination of Sonographic Morphology Score and Tumor Markers for Detecting Postoperative Recurrent Pelvic Ovarian Carcinoma: Compared With MRI Assessment

To assess the efficacy of the combination of sonographic morphology score (SMS) with CA125 and HE4 for detecting recurrent pelvic ovarian carcinoma (OC). Data of 58 OC patients treated in our hospital between 2014 and 2016 were analyzed. After cytoreductive surgery and routine chemotherapy, all patients were followed up by transvaginal ultrasound examination (SMS for pelvic masses based on volume and structure scores) and tumor marker (serum CA125 and HE4) detection. Clinical diagnosis of recurrent OC was based on physical examination, magnetic resonance imaging, and punctured pathology for pelvic masses. Receiver operating characteristic (ROC) curves of SMS and the tumor markers were generated, and areas under the curve (AUC) values were assessed. There were 26 patients with tumor recurrence and 32 cases with no recurrence. Magnetic resonance imaging had 100% sensitivity and specificity. The areas under the ROC curves of SMS, CA125, HE4, and SMS-CA125-HE4 were 0.816, 0.825, 0.737, and 0.903, respectively. There was no significant difference in AUC values between SMS and CA125 or HE4. There were significant differences in AUC values between SMS-CA125-HE4 and SMS (Z = 2.48, P = 0.042), CA125 (Z = 2.38, P = 0.046), and HE4 (Z = 6.48, P = 0.016), respectively. With a cutoff value of SMS, 5; CA125, 35 U/mL; HE4, 105 pmol/L, the sensitivity, specificity, positive prognostic value, and negative prognostic value of SMS-CA125-HE4 for recurrent OC assessment were 0.9231, 0.8438, 0.8276, and 0.931, respectively. SMS-CA125-HE4 was correlated with recurrent OC (χ = 30.7428, P < 0.0001). Ultrasound combined with tumor markers may improve the diagnostic efficiency of recurrent OC.
