Stereotaxis is a well-known technique allowing fine-needle aspiration cytology and preoperative localization of the nonpalpable breast lesions seen on mammograms, permitting early diagnosis and easy surgical ablation. The authors report on their experience (126 cases) with stereotactic aspiration (85 cases) and preoperative localization (41 cases) of nonpalpable lesions. The technique allowed to hit the lesion in 115/126 cases (91.3%). Cytology showed 24 cases of cancer and 38 benign lesions (3 of them were false negatives); in 8 cases cytology was suspect (7 cancers and 1 sclerosing adenosis) and in 15 inadequate (17.7%). Sensitivity and specificity were confirmed by histology or follow-up (6 months + 6 months); sensitivity was 91.2% and specificity 97.2% (excluding inadequate cases). The 41 needle localizers were useful to detect 37 malignancies. Fifty-one lesions were biopsied: 37 of them were malignant and 14 benign (benign/malignant ratio = 0.38/1).
立体定位是一种众所周知的技术，可用于乳腺钼靶检查中不可触及的乳腺病变的细针穿刺细胞学检查和术前定位，从而实现早期诊断和便于手术切除。作者报告了他们对126例不可触及病变进行立体定位穿刺（85例）和术前定位（41例）的经验。该技术在126例中有115例（91.3%）成功命中病变。细胞学检查显示24例为癌症，38例为良性病变（其中3例为假阴性）；8例细胞学检查结果可疑（7例为癌症，1例为硬化性腺病），15例不充分（占17.7%）。通过组织学检查或随访（6个月+6个月）证实了敏感性和特异性；敏感性为91.2%，特异性为97.2%（不包括不充分的病例）。41个针定位器有助于检测出37例恶性肿瘤。对51个病变进行了活检：其中37个为恶性，14个为良性（良性/恶性比例=0.38/1）。
