Value analysis of conventional ultrasound combined with contrast-enhanced ultrasound in diagnosis and staging ofcervical cancer

目的研究常规超声结合超声造影检查宫颈癌的价值与分期效果。方法选取54例宫颈癌患者,将手术病理诊断作为金标准,对全部患者实施常规超声检查结合超声造影检查,观察检查价值。结果常规超声诊断敏感度为0.889,特异度为0.444,准确率为0.815,误诊率为0.556,漏诊率为0.111,阳性预测值为0.889,阴性预测值为0.444,假阳性率为0.556,假阴性率为0.111,正确指数为0.333;超声造影诊断敏感度为0.933,特异度为0.556,准确率为0.870,误诊率为0.444,漏诊率为0.067,阳性预测值为0.913,阴性预测值为0.625,假阳性率为0.444,假阴性率为0.067,正确指数为0.489;联合诊断敏感度为0.980,特异度为0.800,准确率为0.963,误诊率为0.200,漏诊率为0.020,阳性预测值为0.980,阴性预测值为0.800,假阳性率为0.020,假阴性率为0.020,正确指数为0.780。联合诊断效能高于常规超声诊断、超声造影诊断,其中特异度、阴性预测值与单一诊断对比,差异有统计学意义(P<0.05),联合诊断不同分期诊断准确率均高于单一诊断,但差异无统计学意义(P>0.05)。结论常规超声结合超声造影检查方式对宫颈癌诊断价值较高,可实施分期诊断。

Objective To study the value and staging effect of conventional ultrasound combined with contrast-enhanced ultrasound in cervical cancer.Methods 54 patients with cervical cancer were selected,surgical pathology diagnosis was taken as the gold standard,and routine ultrasound combined with contrast-enhanced ultrasound was performed in all patients to observe the value of examination.Results The sensitivity of conventional ultrasound diagnosis was 0.889,the specificity was 0.444,the accuracy was 0.815,the misdiagnosis rate was 0.556,the missed diagnosis rate was 0.111,the positive predictive value was 0.889,the negative predictive value was 0.444,the false positive rate was 0.556,the false negative rate was 0.11l,the correct index was 0.333.The diagnostic sensitivity of CEUS was 0.933,the specificity 0.556,the accuracy was 0.870,the misdiagnosis rate was 0.444,the missed diagnosis rate was 0.067,the positive predictive value was 0.913,the negative predictive value was 0.625,the false positive rate was 0.444,the false negative rate was 0.067,and the correct index was 0.489.Combined diagnostic sensitivity was 0.980,specificity was 0.800,accuracy was 0.963,misdiagnosis rate was 0.200,missed diagnosis rate was 0.020,positive predictive value was 0.980,negative predictive value was 0.800,false positive rate was 0.020,false negative rate was 0.020,correct index was 0.780.The effectiveness of combined diagnosis was higher than that of conventional ultrasound diagnosis and contrast-enhanced ultrasound diagnosis,and the difference of specificity and negative predictive value was statistically significant compared with single diagnosis(P<0.05).The diagnostic accuracy of combined diagnosis at different stages was higher than that of single diagnosis,but the difference was not statistically significant(P>0.05).Conclusion Conventional ultrasonography combined with contrast-enhanced ultrasonography is valuable in the diagnosis of cervical cancer and can be used for staging diagnosis.
