高频彩色多普勒超声对早期乳腺癌的诊断价值分析

Analysis of diagnostic value of high frequency color Doppler ultrasound in early breast cancer

目的分析高频彩色多普勒超声对早期乳腺癌的诊断价值。方法106例接诊的疑似乳腺癌患者为研究对象,所有患者均接受X线钼靶检查与高频彩色多普勒超声。以病理检查结果为金标准,比较两种检查方法的特异度、灵敏度、准确度、漏诊率、误诊率及对乳腺癌患者影像特征的检出情况。结果106例疑似乳腺癌患者,经病理确诊49例,占比46.23%。X线钼靶检查出阳性53例,阴性53例,漏诊9例,误诊13例。高频彩色多普勒超声检查出阳性48例,阴性58例,漏诊2例,误诊1例。高频彩色多普勒超声的特异度、灵敏度、准确度分别为98.25%、95.92%、97.17%,均高于X线钼靶检查的77.19%、81.63%、79.25%(P<0.05)。高频彩色多普勒超声的漏诊率、误诊率分别为4.08%、1.75%,均低于X线钼靶检查的18.37%、22.81%(P<0.05)。高频彩色多普勒超声对乳腺癌患者血流信号异常、肿块、腋窝淋巴结转移、微小钙化的检出率分别为81.63%、95.92%、44.90%、38.78%,均高于X线钼靶检查的34.69%、65.31%、14.29%、61.22%(P<0.05)。结论高频彩色多普勒超声对早期乳腺癌的诊断特异度、灵敏度、准确率高,能够有效降低漏诊率、误诊率;高频彩色多普勒超声对早期乳腺癌检查影像特征明显,更有利于医生的诊疗。

Objective To analyze the diagnostic value of high frequency color Doppler ultrasound in early breast cancer.Methods 106 patients with suspected breast cancer were studied,and all of them received molybdenum target X-ray examination and high-frequency color Doppler ultrasound.The specificity,sensitivity,accuracy,missed diagnosis rate,misdiagnosis rate,and detection of breast cancer imaging features of the two methods were compared using the pathological findings as the gold standard.Results Among 106 suspected patients with breast cancer,49 cases were confirmed by pathology,accounting for 46.23%.Molybdenum target X-ray examination showed positive results in 53 cases,negative results in 53 cases,missed diagnosis in 9 cases,and misdiagnosis in 13 cases.High frequency color Doppler ultrasound showed positive results in 48 cases,negative results in 58 cases,missed diagnosis in 2 cases,and misdiagnosis in 1 case.The specificity,sensitivity and accuracy of high frequency color Doppler ultrasound were 98.25%,95.92% and 97.17%,which were higher than 77.19%,81.63% and 79.25% of molybdenum target X-ray examination(P<0.05).The missed diagnosis rate and misdiagnosis rate of high frequency color Doppler ultrasound were 4.08% and 1.75%,which were lower than 18.37%and 22.81%of molybdenum target X-ray examination(P<0.05).The detection rates of high-frequency color Doppler ultrasound for blood flow signal abnormality,mass,axillary lymph node metastasis,and microcalcifications were 81.63%,95.92%,44.90%,and 38.78%,which were higher than 34.69%,65.31%,14.29%,and 61.22% of molybdenum target X-ray examination(P<0.05).Conclusion High-frequency color Doppler ultrasound has high specificity,sensitivity and accuracy in the diagnosis of early breast cancer,which can effectively reduce the rate of missed diagnosis and misdiagnosis rate.High frequency color Doppler ultrasound has obvious image characteristics for early breast cancer examination,and is more conducive to doctors'diagnosis and treatment.
