病人和方法对全组61例女性病人进行彩色多普勒血流显象,其中乳腺癌28例,乳房纤维腺瘤33例.乳腺癌病人平均年龄54岁,病灶直径8～37mm;乳房纤维腺瘤病人平均年龄38岁,病灶直径5～31mm.结果28例乳腺癌中的21例有血流显像,而在33例乳房纤维腺瘤中仅11例有血流显像,且只有当病灶大于13mm时才出现血流显像.由此可见,乳房恶性肿瘤的血流显像比例明显高于良性病变(P<0.01).乳腺癌病人的动脉收缩期血流速率的均值为1.0kHz,而乳房纤维腺瘤病人动脉收缩期血流速率的均值为0.5kHz.尽管良、恶性病变之间在动脉血流速率上有很大重叠,但5例动脉血流速率超过1.25kHz的均为恶性病变.7例病灶直径小于13mm乳腺癌中有5例监测到血流,且血管数量及动脉收缩期血流速率与病灶直径成正比,而8例直径小于13mm的乳房纤维腺瘤均未出现血流显像.对17例乳腺癌病人进行腋窝扫描,其中5例提示淋巴结周围有血流,但病理检查仅证实3例有腋窝淋巴结转移.12
Patients and Methods 61 cases of female patients in the whole group were subjected to color Doppler flow imaging, including 28 cases of breast cancer and 33 cases of breast fibroadenoma. The average age of breast cancer patients was 54 years old, and the lesion diameter was 8 to 37 mm; breast fibroids The average age of tumor patients was 38 years old and the lesion diameter was 5 to 31 mm. Results The blood flow imaging was performed in 21 of 28 breast cancers, and only 11 of 33 breast fibroadenomas had blood flow imaging, and only when the lesions Only when the blood flow was larger than 13mm, blood flow imaging was observed. This shows that the proportion of blood flow imaging of breast cancer is significantly higher than that of benign lesions (P<0.01). The mean arterial systolic blood flow velocity of breast cancer patients is 1.0 kHz. The mean arterial systolic blood flow rate in patients with breast fibroadenoma was 0.5 kHz. Although there was a large overlap between arterial blood flow rates between benign and malignant lesions, the arterial blood flow rates in excess of 1.25 kHz were malignant in 5 patients. Lesions. 7 cases of lesions less than 13mm in breast cancer were detected in 5 cases of blood flow, and the number of blood vessels and artery systolic blood flow rate is proportional to the diameter of the lesion, and 8 cases of breast fibroadenoma less than 13mm in diameter did not appear blood Flow imaging. Axillary scans were performed on 17 breast cancer patients, 5 of which There was blood flow around the lymph nodes, but pathological examination confirmed only 3 cases of axillary lymph node metastases.12
