This study aimed to evaluate and compare the diagnostic accuracy of two ultrasound scoring systems, Assessment of Different Neoplasias in the Adnexa (ADNEX) Model and Gynecology Imaging Reporting and Data System (GI-RADS), for the preoperative assessment of adnexal masses taking histopathology as gold standard.
This analytical study assessed 60 patients of age > 14 years with adnexal masses, planned for surgery. Ultrasound assessment and risk categorization according to ADNEX and GI-RADS were performed 2-3 days prior to surgery. Histopathology was used as a reference standard for the calculation of validity of two ultrasound scoring systems for diagnosis of adnexal masses.
Out of 60 women (mean age, 35.52 ± 13.86 years; range, 16-70 years) with adnexal masses, 24 were malignant and 36 were benign. The sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and accuracy for the ADNEX model were 87.50%, 91.7%, 87.50%, 91.7% and 90.0%, respectively. The sensitivity, specificity, PPV, NPV and accuracy of the GI-RADS category were 95.8%, 61.1%, 62.2%, 95.7% and 75.0%, respectively. The diagnostic performance of the ADNEX model was better as compared to GI-RADS in terms of specificity and positive predictive value with a significant difference ( < 0.05). The area under curve (AUC) was 0.957 and 0.919 for ADNEX and GI-RADS, respectively ( = 0.252).
Although both ADNEX and GI-RADS systems had satisfactory diagnostic performances and high negative predictive values, the ADNEX model showed better specificity and positive predictive value in comparison with GI-RADS.
本研究旨在以组织病理学为金标准，评估和比较两种超声评分系统——附件不同肿瘤评估（ADNEX）模型和妇科影像报告与数据系统（GI-RADS）——对附件包块术前评估的诊断准确性。
本分析性研究评估了60例年龄大于14岁、计划接受手术的附件包块患者。在手术前2-3天，根据ADNEX和GI-RADS进行超声评估和风险分类。组织病理学用作计算两种超声评分系统诊断附件包块有效性的参考标准。
60例附件包块女性患者（平均年龄35.52±13.86岁；范围16-70岁）中，24例为恶性，36例为良性。ADNEX模型的敏感性、特异性、阳性预测值（PPV）、阴性预测值（NPV）和准确性分别为87.50%、91.7%、87.50%、91.7%和90.0%。GI-RADS分类的敏感性、特异性、PPV、NPV和准确性分别为95.8%、61.1%、62.2%、95.7%和75.0%。在特异性和阳性预测值方面，ADNEX模型的诊断性能优于GI-RADS，差异有统计学意义（<0.05）。ADNEX和GI-RADS的曲线下面积（AUC）分别为0.957和0.919（P=0.252）。
虽然ADNEX和GI-RADS系统都具有令人满意的诊断性能和较高的阴性预测值，但与GI-RADS相比，ADNEX模型显示出更好的特异性和阳性预测值。
