摘要
目的 评价超声引导下粗针活检术 (US CNB)对不可触及的乳腺病变 (NPBL )的诊断意义。方法 对 13 8例女性患者的 162处NPBL进行US CNB和切除活检 ,以切除活检病理结果为诊断标准。结果 NPBL大小为 3～ 2 4mm (平均 11.1mm )。在US CNB标本中 ,14 2处为良性 ,3处为可疑恶性 ,14处为恶性 ,3处取材不当。在手术切除标本中 ,18处为恶性 ,14 4处为良性。US CNB取材不当的 3处均为良性。US CNB诊断阳性率为 94.44% (17/18) ,特异性为 10 0 .0 0 % (14 1/14 1) ,正确率为 99.3 7% (15 8/15 9)。结论 US CNB诊断NPBL安全、创伤小、准确率高。
Objective To assess the accuracy of ultrasound-guided core-needle biopsy(US-CNB) to diagnose nonpalpable breast lesions(NPBL).Methods US-CNB was performed in 162 NPBL of 138 female patients.Subsequently,all patients underwent surgery.The histopathologic findings of all specimens(biopsy and surgery) were correlated.Results The sizes of NPBL were from 3 to 24 mm(mean,11.1 mm).The biopsy results of 142 NPBL were interpreted as benign,3 as suspicious malignancy,14 as malignant,3 as inadequate sample.In all,18 surgical specimens were malignant and 144 were benign.The inadequate samples all were benign.US-CNB had sensitivity of 94.44%(17/18),specificity of 100.00%(141/141) and accuracy 99.37%(158/159).Conclusion US-CNB is a safe and less traumatic accurate procedure and for diagnosis of NPBL.
