摘要
目的：总结乳腺导管原位癌的超声征象，探讨高频超声对其诊断价值。方法：分析经术后病理证实的40例乳腺导管原位癌和30例乳腺增生病的声像图特征，包括边界、内部回声、微钙化、后方回声、峰值血流速度、阻力指数以及血流分布等。结果：乳腺导管原位癌的声像图特征表现为肿块型、片状低回声型、导管扩张型、单纯微钙化型者分别占57.50%（23/40）、27.50%（11/40）、10.00%（4/40）、5.00%（2/40）。7例（17.50%）伴有微浸润，其中1例伴有腋窝淋巴结转移。术前超声正确诊断导管原位癌31例，乳腺增生病24例，其准确性、特异性和敏感性分别为78.57%、80.00%和77.50%。阳性预测值和阴性预测值分别为83.78%和72.73%。微钙化、阻力指数鉴别乳腺导管原位癌和乳腺增生病差异有统计学意义（P<0.05）。结论：乳腺导管原位癌的声像图特点具有一定特征性，高频超声对诊断乳腺导管原位癌有重要价值。
Abstract
Objective: To evaluate the diagnostic value of high frequency ultrasonography(HFUS) through summarizing the ultrasonic signs of ductal carcinoma in situ(DCIS). Methods: The ultrasonographic features in 40 cases of DCIS proved by post-operative pathology and 30 cases of hyperplastic disease of breast(HDB) including boundary, internal echogenicity, microcalcification, posterior echogenicity, peak systolic velocity(PSV), resistance index(RI) and blood distribution, were analyzed. Results: The ultrasonographic features of DCIS are mass-forming type, patchy hypoechoic type, duct dilatation type and microcalcification type, accounted for 57.50%(23/40), 27.50%(11/40), 10.00%(4/40) and 5.00%(2/40), respectively. There are 7 patients with microinvasion, including 1 patient with axillary lymph node metastasis. Thirty-one cases of DCIS and 24 cases of HDB were diagnosed correctly by preoperative ultrasonography, the accuracy, specificity and sensitivity were 78.57%, 80.00% and 77.50% respectively. The positive predictive value and negative predictive value were 83.78% and 72.73% respectively. Microcalcification and RI were statistically significant(P<0.05) in differential diagnosis between DCIS and HDB. Conclusion: The ultrasonic characteristics of DCIS has certain specific features, HFUS diagnosis for DCIS are of great value.
