超声造影对宫颈癌不同分期的诊断价值

The Values of Contrast-enhanced Ultrasonography in the Diagnosis of Different Staging of Different Cervical Cancer

目的探讨超声造影对宫颈癌不同分期的诊断价值。方法选择诊治的162例宫颈癌患者,所有患者都给予常规超声、超声造影与病理检查,记录超声特征,同时进行临床病理分期与超声造影分期,判定分期诊断价值。结果在162例宫颈癌患者中,病理学确诊为早期组100例,晚期组62例,其中Ⅰ期64例,Ⅱ期36例,Ⅲ期40例,Ⅳ期22例。晚期组患者的年龄、体重指数、病程、病灶直径等与早期组患者对比差异无统计学意义(P>0.05)。晚期组患者的常规超声病灶形态、晕环、钙化、边界、内部回声等特征与早期组患者对比差异有统计学意义(P<0.05)。晚期组患者的PI值高于早期组患者(P<0.05),2组TP与AUC值对比差异无统计学意义(P>0.05)。在162例宫颈癌患者中,超声造影诊断为Ⅰ期67例,Ⅱ期35例,Ⅲ期38例,Ⅳ期22例,检出正确率为96.3%。结论超声造影在宫颈癌的鉴别诊断中具有重要意义,有助于提高临床分期的准确性。

Objective To investigate the diagnostic values of contrast-enhanced ultrasonography in the diagnosis of different staging of cervical cancers.Methods 162 patients with cervical cancer were selected.All patients were given conventional ultrasound,contrast-enhanced ultrasonography and pathological examination.The ultrasonographic features were recorded,and the clinical pathological staging,ultrasound contrast staging were recorded,and to determine the values of staging diagnosis.Results The pathology were confirmed as 100 patients in the early group and 62 patients in the advanced group in the 162 patients with cervical cancers that included 64 patients in stageⅠ,36 patients in stageⅡ,40 patients in stageⅢ,and 22 patients in stageⅣ.There were no significant differences in age,body mass index,duration of disease,and lesion diameter compared between the advanced group and the early group(P>0.05).The characteristics of conventional ultrasound lesions,halo,calcification,border,internal echo,etc.in the advanced group were significantly different from those of the early group(P<0.05).The PI value of patients in the advanced group were higher than that of the early group(P<0.05).There were no significant difference compared between the 2 groups in TP and AUC(P>0.05).In 162 patients with cervical cancer,the diagnosis of contrast-enhanced ultrasound were 67 patients in stageⅠ,35 patients in stageⅡ,38 patients in stageⅢ,and 22 patients in stageⅣ,so that the correct rates were 96.3%.Conclusion Contrast-enhanced ultrasonography is of great significance in the differential diagnosis of cervical cancer,which helps to improve the accuracy of clinical pathological staging.
