| 目的：探讨ROC曲线评价彩色多普勒超声血流成像(CDFI)收缩期与舒张末期流速比(S/D)值在鉴别卵巢良恶性肿瘤中的价值,以为临床诊断提供依据。方法：选取2015年12月至2018年12月我院确诊治疗的卵巢癌患者96例作为癌症组,同期选取卵巢良性病变患者96例作为对照组,所有患者均给予CDFI检查并测定血流分级、S/D值,以病理学检查为标准,采用ROC 曲线评估S/D值鉴别卵巢良恶性肿瘤的效能。结果：癌症组血流分级、S/D值明显高于对照组,差异有统计学意义(P<0.05)；在鉴别卵巢良恶性肿瘤敏感度、特异度、准确度中,血流分级以≥Ⅱ级为临界值时分别为81.25%、83.33%、82.29%,ROC曲线显示S/D值以≥2.20为临界值时分别为87.50%、81.25%、84.38%,两者联合时分别为95.83%、93.75%、94.79%,两者联合时明显高于两者单独时,差异有统计学意义(P<0.05),但两者单独时基本相同,差异无统计学意义(P>0.05)。结论：血流分级及ROC曲线评价S/D值对鉴别卵巢良恶性肿瘤具有良好的效能,联合应用时可进一步提高其鉴别效能。 |

| Abstract: |
| 【S】objective:To discuss the value of ROC curve evaluation of color doppler ultrasound blood flow imaging (CDFI) systolic and diastolic velocity ratio (S/D) in differentiating benign and malignant ovarian tumors,in order to provide a basis for clinical diagnosis.Methods: 96 patients with ovarian cancer were selected as cancer group from December 2015 to December 2018 in our Hospital,96 patients with ovarian benign lesions were selected as control group at the same period,the thrombolysis in myocardial infarction,S/D value were assessed by CDFI examination and determination in all patients,the S/D value in differentiating benign and malignant ovarian tumors was evaluated by ROC curve.Results:The thrombolysis in myocardial infarction,S/D value of cancer group were significantly higher than those of control group,the difference was statistically significant (P < 0.05).In terms of the sensitivity, specific, accuracy degree for differentiating benign and malignant ovarian tumors,when thrombolysis in myocardial infarction for ≥Ⅱlevel as the critical value,they were 81.25%,83.33%,82.29%,when S/D value by ROC curve for ≥2.20 as the critical value,they were 87.50%,81.25%,84.38%,when they joint,they were 95.83%,93.75%,94.79%,when they joint were significantly higher than those of when thrombolysis in myocardial infarction for and PSV separate identification, the difference was statistically significant (P < 0.05),but when they separate identification were basically the same , there was no statistically significant difference (P > 0.05).Conclusions:Thrombolysis in myocardial infarction and S/D value by ROC curve has good effectiveness in differentiating benign and malignant ovarian tumors,and when they joint can further improve the identification efficiency. |
