To assess the contribution of mammography in the detection of cancer in the contralateral breast in women with bilateral breast cancer.
Mammograms and clinical records of 77 patients with bilateral breast cancer were reviewed in a retrospective study.
The contralateral cancer was detected at mammography in 68 of 77 patients (88%) and identified at mammography alone in 50 patients (65%). No statistically significant differences in either mammographic detection rates or stage of the contralateral cancer were noted in patients younger than 50 years (n = 25) compared with those 50 years of age or older (n = 52). Cancers detected at annual screening mammography were of lower stage than cancers in unscreened patients. In the screened group, 41% of tumors were ductal carcinoma in situ alone and 23% were stage II or III, compared with 22% and 50%, respectively, in the unscreened group.
Mammographic examination and follow-up in patients with unilateral breast cancer allow detection of the majority of contralateral breast cancers and earlier stage cancers.
评估乳腺钼靶摄影在双侧乳腺癌患者对侧乳腺癌检测中的作用。
在一项回顾性研究中，对77例双侧乳腺癌患者的乳腺钼靶片和临床记录进行了回顾。
77例患者中有68例（88%）在乳腺钼靶摄影时检测到对侧癌，其中50例（65%）仅通过乳腺钼靶摄影发现。与50岁及以上患者（n = 52）相比，50岁以下患者（n = 25）在乳腺钼靶检测率或对侧癌分期方面均未观察到统计学上的显著差异。年度筛查乳腺钼靶摄影检测出的癌症分期低于未进行筛查患者的癌症分期。在筛查组中，41%的肿瘤仅为导管原位癌，23%为II期或III期，而在未筛查组中分别为22%和50%。
对单侧乳腺癌患者进行乳腺钼靶检查及随访可检测出大多数对侧乳腺癌及早期癌症。
