经阴道彩色多普勒超声检查在早期宫颈癌诊治中的应用分析

Application of Transvaginal Color Doppler Ultrasonography in the Diagnosis of Early Cervical Cancer

目的探讨早期宫颈癌诊治中经阴道彩色多普勒超声检查的应用效果。方法选取疑似宫颈癌患者125例,均行经阴道彩色多普勒超声检查,并以病理组织活检结果为金标准进行对比。结果经病理组织活检检查,早期宫颈癌80例,癌前病变45例。经阴道彩色多普勒超声诊断准确性为84. 00%,敏感性为93. 75%,特异性为66. 67%,阳性预测值为83. 33%,阴性预测值为85. 71%。早期宫颈癌患者左右径、前后径均高于非宫颈癌患者,差异有统计学意义(P <0. 05);早期宫颈癌患者收缩期峰值血流速度(PSV)指数均高于非宫颈癌患者,差异有统计学意义(P <0. 05)。结论经阴道彩色多普勒超声检查可快速显示宫颈大小及血流变化情况,为早期宫颈癌诊断提供依据。

Objective To investigate the application effect of transvaginal color Doppler ultrasonography( CDUS) in the diagnosis of early cervical cancer. Methods 125 patients with suspected cervical cancer were selected for transvaginal CDUS. The results of CDUS were compared with the results of pathological biopsy as the gold standard. Results The pathological biopsy revealed that there were 80 cases of early-middle cervical cancer and 45 cases of precancerous lesions in 125 suspected cases. The accuracy of transvaginal CDUS was84. 00%,the sensitivity was 93. 75%,the specificity was 66. 67%,the positive predictive value was 83. 33%,and the negative predictive value was 85. 71%. The left-right diameter and anteroposterior diameter of patients with early cervical cancer were higher than those of non-cervical cancer patients,and the difference was statistically significant( P < 0. 05). The peak systolic velocity( PSV) of patients with early cervical cancer were higher than those of non-cervical cancer patients,and the difference was statistically significant( P < 0. 05). Conclusion Transvaginal CDUS can quickly display the size of the cervix and changes of blood flow,and provide a basis for the diagnosis of early cervical cancer.
