Stereotactic breast biopsy has been developed as a less invasive means of performing biopsy for mammographic abnormalities.
From July 1994 through June 1995, 103 women with mammographic abnormalities requiring biopsy were prospectively evaluated.
Fifty-one women had open biopsy, and 52 women had stereotactic biopsy. The average age in both groups was 60 years. Pathology revealed malignancy in 12% of stereotactic biopsies and 13% of open biopsies. Complications occurred in 6% of the open biopsies and 4% of the stereotactic biopsies and were limited to hematomas or seromas. The average cost was $2400 for open biopsy and $650 for stereotactic biopsy (P < 0.01). One hundred and one patients returned for a follow-up mammogram within 6 months, and 1 patient in each group required a second biopsy, which revealed benign pathology. A Patient Satisfaction Survey revealed no significant differences in patient satisfaction between the two types of procedures.
There were no differences between open and stereotactic biopsies in regards to diagnostic accuracy, complications, or patient satisfaction. A significant difference was noted in charges during the time frame of our study.
立体定向乳腺活检已发展成为一种对乳腺钼靶异常进行活检的侵入性较小的方法。
从1994年7月至1995年6月，对103例需要活检的乳腺钼靶异常女性进行前瞻性评估。
51例女性接受了开放活检，52例女性接受了立体定向活检。两组的平均年龄均为60岁。病理检查显示，立体定向活检中有12%为恶性，开放活检中有13%为恶性。开放活检中有6%发生并发症，立体定向活检中有4%发生并发症，且均局限于血肿或血清肿。开放活检的平均费用为2400美元，立体定向活检的平均费用为650美元（P < 0.01）。101例患者在6个月内返回进行随访乳腺钼靶检查，每组各有1例患者需要进行第二次活检，结果显示为良性病理。患者满意度调查显示，两种手术方式在患者满意度方面没有显著差异。
开放活检和立体定向活检在诊断准确性、并发症或患者满意度方面没有差异。在我们的研究时间段内，费用方面存在显著差异。
