To determine the mammographic, histologic, and clinical features of bilateral breast cancer.
Pre-biopsy mammograms of 67 patients with bilateral carcinoma were reviewed. Lesions were synchronous in 35 patients and metachronous in 32. Mammographic appearance, lesion size and location, and bilateral similarities were evaluated. Axillary nodal status was noted. These characteristics were compared with those of unilateral cancers.
Of 58 mammographically evident lesion pairs, 31 involved the same quadrant. Of the total 67 lesion pairs, 24 pairs were similar in appearance, and 15 had both mirror image location and a similar appearance. Of 17 lesion pairs considered to represent a single primary carcinoma with metastases to the contralateral breast, eight had a similar mirror image appearance and five had mirror image location and a similar mirror image appearance. The second cancer of metachronous pairs was smaller, with less frequent axillary nodal involvement.
The appearance of bilateral breast cancer does not differ from that of unilateral carcinoma. Bilateral breast carcinomas frequently demonstrate a similar mammographic appearance and mirror image location.
确定双侧乳腺癌的乳腺X线摄影、组织学和临床特征。
回顾了67例双侧癌患者活检前的乳腺X线片。35例患者的病变为同时性，32例为异时性。评估乳腺X线表现、病变大小和位置以及双侧的相似性。记录腋窝淋巴结状态。将这些特征与单侧癌的特征进行比较。
在58对乳腺X线可见病变中，31对累及同一象限。在总共67对病变中，24对外观相似，15对具有镜像位置且外观相似。在17对被认为代表单一原发性癌并转移至对侧乳腺的病变中，8对具有相似的镜像外观，5对具有镜像位置和相似的镜像外观。异时性病变对中的第二个癌较小，腋窝淋巴结受累频率较低。
双侧乳腺癌的表现与单侧癌无异。双侧乳腺癌常表现出相似的乳腺X线外观和镜像位置。
