目的:探讨超声对临床触诊阴性乳腺癌的诊断价值。方法:回顾性分析135个临床触诊阴性乳腺肿块(恶性33个,良性102个)超声直接和间接征象图特征,并与病理结果对照分析,计算超声诊断触诊阴性乳腺肿块灵敏性、特异性、阳性预测值、阴性预测值及准确性。结果:直接征象中微钙化、Ⅱ～Ⅲ级血流、穿支血管、阻力指数RI≥0.7和间接征象中浅筋膜的改变、腋窝淋巴结肿大具有较高诊断价值,良恶性组比较差异有统计学意义(P均<0.01)。超声诊断临床触诊阴性乳腺癌的灵敏性81.82%、特异性93.14%、阳性预测值79.41%、阴性预测值94.06%、准确性90.37%。结论:超声对临床触诊阴性乳腺癌的早期诊断具有重要价值。
Objective: To investigate the diagnostic value of ultrasound in clinical palpation-negative breast cancer. Methods: The characteristics of direct and indirect signs of 135 cases of clinical palpation-negative breast masses (33 malignant and 102 benign) were retrospectively analyzed. The sensitivity and specificity of sonographic diagnosis of palpation negative breast mass , Positive predictive value, negative predictive value and accuracy. Results: The direct signs of micro-calcification, grade Ⅱ ~ Ⅲ blood flow, perforating branches, resistance index RI ≥ 0.7 and changes in the indirect signs of shallow fascia, axillary lymph node enlargement has a higher diagnostic value, benign and malignant groups were Statistical significance (P <0.01). The sensitivity, specificity and accuracy of ultrasonic diagnosis of clinical palpation negative breast cancer were 81.82%, 93.14%, 79.41%, 94.06% and 90.37% respectively. Conclusion: Ultrasound is of great value in the early diagnosis of clinical palpation-negative breast cancer.
