临床未扪及肿块的乳腺病灶穿刺活检现状

对于影像学诊断发现的临床摸不到块的乳腺病灶 ,可以采用B超或者X线立体定位下进行活检。细针吸取细胞学检查 (FNA)和空心针穿刺活检 (CNB)是目前最常用的两种穿刺活检诊断方法。对于乳腺X线异常的病灶 ,X线立体定位穿刺活检不仅诊断敏感性高 ,而且可以使大量良性病变免于不必要的手术 ;另外它还有助于手术方案的制定。由于存在组织学低估以及漏检等情况 ,穿刺活检尚不能完全取代手术活检。因此 ,必须合理地选择穿刺对象及掌握再次活检的指征

Current status of needle biopsy for non-palpable breast lesion

Non palpable breast lesion can be biopsied with the guiding under the B Ultrasound and stereotactic system.Fine Needle Aspiration (FNA) and Core needle biopsy (CNB) are currently two of the most comman needle biopsy methods for those lesion.Stereotactic core needle biopsy is utilized as screening for mammographic abnormalities because of high diagnostic sensitivity and avoidance of open biopsy for benign lesion.Furthermore, they also allow treatment planning before surgery.But for the histologic underestimation and some missed case,needle breast biopsy could not completely replace excisional biopsy.More attention should be paid to patient selection and rebiopsy indication.
