乳腺癌的彩色多普勒血流分布特征与组织病理学对照研究

Control study of flow imaging and histological features of color Doppler for breast cancer

目的探讨乳腺癌的彩色多普勒血流分布特征与组织病理学的相关性。方法回顾性研究203例患者的210个乳腺病变部位的彩色多普勒血流分布特征，分析血流分布特征与组织病理学问的关系。结果210个乳腺癌病灶中有周边型血流118个（56．1％），穿入型46个（21．9％），内部型37个（17．6％），9个（4．2％）无血流；导管内癌、高、中分化的浸润性导管癌、浸润性小叶癌主要以周边型血流为主，而低分化的浸润性导管癌以穿入型血流为主；血流分布为内部型的肿瘤多数表现为血流丰富（P〈0．05）。结论血流分布类型、血管数量与乳腺癌的生长、分化存在一定的关系。

Objective To investigate the correlation between the color Doppler ultrasound flow imaging and histological features of breast cancers. Methods The color Doppler flow imaging of 210 ca- ses of breast cancers were studied retrospectively. The relationship between the blood flow distribution features and histopathology was analyzed. Results In 210 breast lesions, the peripheral vascular was detected in 118 （56. 1% ）, penetrating vascular in 46 （21.9%）, central vascular in 37 （ 17.6% ）, and avascular in 9 （4. 2% ）. Besides, peripheral vascular was more common in ductal carcinomas in situ, and in the invasive ductal carcinoma grade Ⅰ / Ⅱ , while grade m often showed penetrating vessels. The tumor which was central vascular showed rich blood mostly （ P 〈 O. 05 ）. Conclusions The location of tumor vessels is an important feature to breast cancers, which related to the cancer＇ s histopathology.
