小乳癌的数字化乳腺摄影与超声成像对比研究

目的探讨数字化乳腺摄影与彩色多普勒超声对小乳癌及腋淋巴结转移的诊断价值。方法60例≤2.0cm(包括未形成肿块的早期乳腺癌)乳腺结节的数字化影像和超声资料分别由影像和超声医师用双盲法分析,定性诊断,并与病理对照。结果60例中,乳腺癌36例,良性病变24例;发现腋淋巴结96个,45个有转移。数字化摄影和超声在诊断小乳癌的敏感性、准确性及腋淋巴结转移的敏感性方面,二者差异显著(P(0.05);对直径≤1.0cm的病灶,数字化摄影的准确性明显高于超声(P(0.05)。结论对小乳癌及其腋淋巴结的定性诊断方面,数字化摄影为首选,二者结合有利于发现更早期的乳腺癌。

Comparative Study on Small Breast Carcinoma Digital Mammography and Color Doppler Ultrasonography

Objective To study the diagnostic value of digital mammography(DM) and color Doppler ultrasonography (CDUS) for small breast carcinoma and axillary lymph nodes metastasis.Methods DM and ultrasonographic findings of 60 cases with breast nodules less than 2.0 cm in diameter were analyzed and diagnosed by experienced radiologists and ultrasonography doctors with double blind method and compared with pathological results.Results Among 60 cases, 60 breast nodules and 96 axillary lymph nodes (45/96 metastatic nodes) were both found by DM and CDUS,including 36 cases of breast cancer and 24 cases of benign lesions. The sensitivity and accuracy of DM in diagnosis of small breast cancer and axillary lymph nodes metastasis were significantly higher than that of CDUS, especially for the lesions were less than 1 cm in size (P<0.05).Conclusion DM can be used as the first diagnostic method for small breast cancer and axillary lymph node metastasis , but combining DM with CDUS can improve the assessment of early breast cancer .
