Abstract

Background: Stereotactic breast biopsies have become the gold standard for tissue diagnosis in non-palpable, sonographically occult breast abnormalities seen on mammogram. Only limited data exist in South Africa on the correlation between imaging findings and stereotactic biopsy histology.

Objectives: To describe the mammographic findings and histological diagnosis in patients who underwent stereotactic breast biopsy at a referral hospital. In addition, to evaluate the proportion of malignancy in each Breast Imaging Reporting and Data System (BI-RADS) category.

Method: A retrospective review of stereotactic breast biopsies was performed. Imaging characteristics (including BI-RADS category) and histological diagnosis were recorded. Using histopathology, cases were classified as benign, high-risk or malignant.

Results: A total of 131 biopsies, from 123 patients, were included in the study. Most biopsies were performed on asymptomatic patients (79.3%, 104/131). The majority were categorised as BI-RADS 4 and demonstrated calcifications. Histology revealed a malignant diagnosis in 40 (30.5%) patients, a high-risk lesion in 8 (6.1%) patients and a benign diagnosis in 83 (63.4%) patients. There was a stepwise increase in the proportion of malignancy from BI-RADS category 3 to 5. When compared with surgical histology, the stereotactic biopsies demonstrated an overall ductal carcinoma in situ (DCIS) underestimation rate of 10.3%.

Conclusion: Despite resource restrictions, stereotactic breast biopsies performed in a South African context produce radiological-pathological concordance in keeping with BI-RADS guidelines, as well as with local and international studies.

立体定向乳房活检:在南非转诊单位放射病理学一致性。
背景:乳房立体定向活检已成为乳房x光检查中不可触及、超声隐匿性乳房异常组织诊断的金标准。只有有限的数据存在于南非的影像发现和立体定向活检组织学之间的相关性。目的:描述在转诊医院行立体定向乳腺活检患者的乳房x线摄影表现和组织学诊断。此外,评估乳腺成像报告和数据系统(BI-RADS)各类别中恶性肿瘤的比例。方法:回顾性回顾立体定向乳房活检。记录影像学特征(包括BI-RADS分类)和组织学诊断。根据组织病理学将病例分为良性、高危和恶性。结果:123例患者共131例活检纳入研究。大多数活检是在无症状患者中进行的(79.3%,104/131)。大多数被归类为BI-RADS 4,并表现出钙化。组织学诊断为恶性病变40例(30.5%),高危病变8例(6.1%),良性病变83例(63.4%)。恶性肿瘤的比例从BI-RADS 3级逐步增加到5级。与手术组织学相比,立体定向活检显示整体导管原位癌(DCIS)低估率为10.3%。结论:尽管资源有限,在南非背景下进行立体定向乳房活检产生符合BI-RADS指南的放射-病理一致性,以及当地和国际研究。
