乳腺癌的超声与X线钼靶对比及联合应用

目的:评价超声与X线钼靶检查及两者联合应用对乳腺癌的诊断价值.方法:分析159例(191个)乳腺肿块患者的术前超声与X线钼靶检查表现,观察其中47例乳腺癌伴患侧腋窝淋巴结转移情况,将2种检查方法及两者联合结果分别与手术病理结果进行对照分析,重点分析超声与X线钼靶及两者联合应用的误诊、漏诊病例.结果:超声和X线钼靶摄片检查诊断乳腺癌灵敏度、特异度、准确性差异无统计学意义(P＞0.05);两者联合应用的灵敏度与超声、X线钼靶比较有明显差异(P＜0.01),特异度无明显差异(P＞0.05),与单独X线钼靶比较准确性差异有统计学意义(P＜0.05);超声与X线钼靶比较诊断乳腺癌患侧腋窝淋巴结转移准确性差异有统计学意义(P＜0.01).结论:超声与X线钼靶摄片检查联合应用能提高乳腺癌的灵敏度和诊断准确性,降低乳腺癌的漏诊率,超声检出腋窝淋巴结转移的能力优于X线钼靶.

Comparative studies of Ultrasonography, Mammagraphy and Ultrasonography combined Mammagraphy in patients with Breast Carcinoma

Objective:To assess the value of Ultrasonography(US),mammography and combination of both modalities in diagnoses of breast carcinoma.Methods:191 breast lesions in 159 patients and axillary lymph metastasis in 47 patients with breast carcinoma were observed and analyzed by means of US,mammography and combination of both modalities preoperatively.All cases were confirmed by means of surgery and pathological examinations.The cases of omission and different diagnoses by the three modalities were especially discussed.Results:There was no statistical difference in the sensitivity,specificity and accuracy to breast carcinoma between US and mammography(P>0.05).The combination of both modalities shew very higher sensitivity than that of US and mammography(P<0.01) in diagnosing breast carcinoma.There was no statistical value in the specificity to tell breast carcinoma by means of US,mammography and combination of both modalities(P>0.05).The combination of both modalities provided higher accuracy than that of the single mammography(P<0.05) for diagnosing breast carcinoma.US shew very higher precision in the detection of axillary lymph metastasis in patients with breast carcinoma than that of mammography(P<0.01).Conclusion:The combination of US and mammography not only improved the diagnostic sensitivity and accuracy,but also decreased diagnoses of omission to breast carcinoma.Compared with mammography,US could easily detect the axillary lymph metastasis in patients with breast cancer.
