65例乳腺隐匿性病灶的诊断与治疗体会

目的探讨乳腺X线、超声立体定位细针活检技术对不可能触及的乳腺灶的诊断价值。方法对65例临床未触及乳腺病变（notaetic mammograpy needle localized biopsy, SNLB）,行超声立体定位活检，并进行组织病理学检查。结果65例乳腺病变中，恶性病变42例（64．6％），其中导管内癌12例，浸润性导管癌16例，单纯癌9例，髓样癌3例，大汗腺癌2例；良性病变23例（35．4％），其中乳腺导管内乳头状瘤8例，乳腺非典型增生8例，乳腺小叶增生7例。结论立体定位细针活检对不可触及的乳腺病变的定位定性诊断以及对早期乳腺癌诊断有重要价值。

65 ses nonpalpable breast lesions of diagnosis and treatment

Objective TO invesigate the stereotaxic mammography needle localization and color ultrasound-guided biopsy in the siagnosis of nonpalpable breast lesion （NPBL）. Methods During Oct. 1999 to Oct. 2004,SNLB and color ul- trasound-guided biopsy were performed on 65 cases with clinical nonpalpable breast lesion and analysed by pathological. Results In this 65 breas foic,42（64.6%）patients were proved malignant by pathology,Among them,12 intraductal carci- noma,16 infitration cancer, 9 simple cancer, 3 medullary cancer and 2 apocrine eancer; the lesion was benign in 23 （35.4 %）,of which the papilloma 8,atpical hyperplasaia 8 and mammary lobule hyperplasia 7. Conclusion SNLB is of great significance about location and qualitative determination for dingnosing nonpalpable breast lesion. It can play a sing- nificant role in clinical dingnosis of nonpalabe breast lesion.
