【摘要】：目的比较超声国际卵巢肿瘤研究组(IOTA)简单法则与妇科影像报告与数据系统(GI-RADS)诊断卵巢肿瘤的价值。方法由高年资医师运用IOTA简单法则对463例卵巢肿瘤进行分类,将诊断为良性和恶性的卵巢肿瘤纳入研究。然后,由低年资和高年资医师在互不知道检查结果的情况下分别运用IOTA简单法则和GI-RADS分类进行诊断,定义低年资医师采用IOTA简单法则诊断为A1组,高年资医师采用IOTA简单法则诊断为B1组,低年资医师采用GI-RADS诊断为A2组,高年资医师采用GI-RADS诊断为B2组,比较两种方法的诊断效能。结果 463例病例中,高年资医师IOTA确认良性及恶性的卵巢肿瘤共411例(411/463,88.77%),不能确定性质的52例(52/463,11.23%)。A2与B2组间、A1与A2组间特异度、阳性预测值和诊断正确率差异均有统计学意义(P均0.05),敏感度与阴性预测值差异无统计学意义(P均0.05)。诊断效能各指标在A1与B1组间、B1与B2组间差异均无统计学意义(P均0.05)。结论 IOTA简单法则和GI-RADS分类对卵巢良恶性肿瘤的诊断效能相当且均较高。IOTA简单法则不存在经验依赖性,但不适合全部卵巢肿瘤的评价。
[Abstract]:Objective to compare the diagnostic value of simple rule of IOTAA and gynaecological imaging report and data system (GI-RADS) in the diagnosis of ovarian neoplasms. Methods 463 cases of ovarian neoplasms were classified by using IOTA's simple rule, and the benign and malignant ovarian tumors were included in the study. Then, using IOTA simple rule and GI-RADS classification, the junior and senior doctors were diagnosed by IOTA simple rule and GI-RADS classification without knowing the results of the examination, and the junior doctors were defined as A1 group by IOTA simple rule. Senior doctors were diagnosed as B1 group by IOTA simple rule, second group by GI-RADS and B2 group by GI-RADS. The diagnostic efficacy of the two methods was compared. Results among 463 cases, 411 cases of benign and malignant ovarian tumors were confirmed by IOTA, and 52 cases (52 / 463 / 463) of benign and malignant ovarian tumors were confirmed by IOTA. The specificity of A1 and A2 between group A2 and B2 was not determined. The difference of positive predictive value and diagnostic accuracy was statistically significant (P < 0.05), but there was no significant difference between sensitivity and negative predictive value (P < 0.05). There was no significant difference in diagnostic efficacy between group A1 and group B1 between group B 1 and group B2 (P < 0.05). Conclusion IOTA simple rule and GI-RADS classification have the same diagnostic efficacy for benign and malignant ovarian tumors. The simple rule of IOTA is not empirically dependent, but it is not suitable for the evaluation of all ovarian tumors.
