小乳腺癌超声直接及间接征象的诊断价值

摘要

Objective To explore the value of direct and indirect ultrasonographic signs in diagnosis of small breast cancer. Methods The sonographic features of 103 small breast lesions (47 malignant, 56 benign) were retrospectively analyzed and divided into direct and indirect signs according to the pathology.The results of ultrasonography were compared with pathology. Agreement was measured with K statistics between ultrasonographie signs and pathology. Results Compared with the malignant and benign small breast noplasms, there was statistical significance of the direact signs of micro calcifications, grade Ⅱ- Ⅲ flow,resistance index (RI)≥0.7 and the indireact signs of changes of superficial fascia (P<0.01).Agreement was moderate for micro calcifications, grade Ⅱ-Ⅲ flow, RI≥0.7, changes of superficial fascia (0.7> K≥0.4) ,and substantial for the combination of direct and indirect signs(K=0.726). Conclusions Combination of direct and indirect ultrasonographie signs was significant in diagnosis of small breast cancer.%目的 探讨小乳腺癌超声直接征象及间接征象的诊断价值.方法 回顾性分析103个乳腺小肿块(恶性47个,良性56个)声像图特征,将其按病理改变分为直接征象及间接征象,并与病理结果对照分析,用K系数检验超声征象和病理的吻合度.结果 直接征象中微钙化、Ⅱ～Ⅲ级血流、阻力指数(RI≥0.7),及间接征象中浅筋膜的改变恶性与良性小肿块相比差异有统计学意义(P<0.01),与病理吻合度一般(0.7>K≥0.4),综合分析直接及间接征象与病理吻合度较强(K=0.726).结论 综合分析超声直接征象与间接征象对诊断小乳腺癌具有重要价值.
