摘要
目的:探讨数字化x线立体定位真空辅助活检术对临床触诊阴性乳腺癌的早期诊断价值。方法:2007年10月至2009年9月南方医科大学附属深圳市妇幼保健院应用Lorad数字化钼靶机和Lorad Multicare俯卧式活检系统引导Vacora对243例临床不可触及的可疑病灶(BI-RADS评级为Ⅳ级及以上)行真空辅助活检术。结果:活检成功率为99.6%(242/243),手术时间20～60min,中位时间32min。术后病理:乳腺导管内癌21例、导管内癌伴微浸润7例、浸润性导管癌2例、浸润性小叶癌1例:病理分期:0期21例、Ⅰ期9例、ⅡA期1例;乳腺导管上皮不典型增生22例,占活检总数的9.1%。术后出现皮下瘀斑15例、血肿形成11例,未见其他严重手术并发症。结论:数字化俯卧式穿刺活检定位系统引导Vacora真空负压辅助活检系统(10G)对钼靶下的乳腺微小病灶的活检术,具有活检定位精准、手术成功率高、创伤小等特点,对T_0期乳腺癌的早期诊断有较高的临床应用价值。
Objective： T0 evaluate the advantages of stereotactic biopsy with vacuum-assisted biopsy device in early diagnosis of Stage-T0 breast cancer patients. Methods： From October 2007 to September 2009, The Vacora vacuum-assisted biopsy device was conducted in 243 cases with clinically non-palpable suspicious lesions （Stage-Ⅳ and above by BI-RADS rating） in our hospital. Stereotactic biopsy was performed with Lorad Multicare Prone Breast Biopsy System with digital imaging capabilities （StereoGuide with Digital Spot Mammography; LoRad, US）. Results： The success rate of biopsy was 99.6% （242/ 243）. The time of surgery ranged from 20 to 60 minutes, with the median time of 32. Post-operative pathological examination demonstrated that ductal carcinoma in situ occurred in 21 of the cases, ductal carcinoma in situ with micro-invasion in 7 cases, infiltrating duct carcinoma in 2 cases, and invasive Iobular carcinoma in 1 case. Based on the pathologic TNM staging, there were 21 cases with Stage-0, 9 cases with Stage-I, and 1 case with Stage-IIA. Atypical hyperplasia was found in 21 cases, accounting for 9.1% of the total undergoing the biopsy. Postoperative complications included subcutaneous ecchymosis in 15 cases and hematoma in 11 cases. No other severe complications were found. Conclusion： The MultiCare digital intervention system guided Vacura vacuum biopsy is valuable in assessing the impalpable breast lesions in early diagnosis of Stage-T0 breast cancer patients.
