超声引导穿刺活检对乳腺肿物的诊断价值

目的:探讨超声引导下穿刺活检（ultrasound guided-core needle biopsy，US-CNB）对乳腺肿物的诊断价值。方法:收集2014年1月至2014年12月在哈尔滨医科大学附属肿瘤医院门诊及住院期间进行超声引导下穿刺活检的乳腺肿物患者的病理诊断结果，并与其术后病理结果进行一致性分析，并将超声下病灶≤2 cm的单独列出，检验其一致性。结果:总体上，US-CNB病理诊断结果与术后病理诊断结果的一致率为96.8%，一致性极好，乳腺病灶≤2 cm的比例为54.5%，一致率为95.7%，较总体一致率相差不大，而在一致性方面极高。结论:US-CNB技术作为术前诊断方法之一，对超声下乳腺较小病灶具有较好的诊断价值。

Clinical value of ultrasound-guided biopsy in the diagnosis of breast tumor

Objective:To investigate the clinical value of ultrasound guided-core needle biopsy (US-CNB) in the diagnosis of breast tumor.Methods:The pathological diagnosis of patients undergoing ultrasound-guided percutaneous biopsy during the outpatient and inpatient period from January 2014 to December 2014 in Cancer Hospital of Harbin Medical University was retrospectively collected and compared with the postoperative pathological results.Results:Overall，the coincident rate of pathological diagnosis of US-CNB and postoperative pathological diagnosis was 96.8%.The consistency was excellent.The proportion of breast lesions ≤ 2 cm was 54.5%，and the coincidence rate was 95.7%，which was not different from the overall consistency rate，while the consistency is still high.Conclusion:As one of the preoperative diagnostic methods，US-CNB technique still has a good diagnostic value for the smaller breast lesions under ultrasound.
