| 目的 探讨超声与数字钼靶X线摄影及两者联合对不同级别乳腺导管原位癌(DCIS)的诊断价值。 方法 收集我院经手术病理确诊的DCIS患者38例,比较超声与数字钼靶X线摄影及两者联合对不同级别DCIS的诊断符合率及微钙化特征。 结果 高级别DCIS 20例,低级别和中级别DCIS 18例;单纯DCIS 28例,DCIS伴微浸润10例。超声对DCIS、高级别DCIS、低级别和中级别DCIS诊断符合率分别为73.68%(28/38)、90.00%(18/20)和55.56%(10/18)。数字钼靶X线摄影对DCIS、高级别DCIS、低级别和中级别DCIS诊断符合率分别为76.32%(29/38)、90.00%(18/20)、61.11%(11/18)。两者联合对DCIS、高级别DCIS、低级别和中级别DCIS诊断符合率分别为78.95%(30/38)、90.00%(18/20)、66.67%(12/18)。超声与数字钼靶X线摄影对DCIS的微钙化检出率均为57.89%(22/38)。 结论 超声与数字钼靶X线摄影对DCIS的诊断符合率与微钙化发现率相似,直径>20 mm的DCIS常伴有微浸润,直径<10 mm无钙化的DCIS易于漏误诊。 |

| Objective To assess the diagnostic value of ultrasonography (US), digital mammography (DM) and the combination of them (US+DM) in ductal carcinoma in situ (DCIS) of breast. Methods Thirty-eight patients of DCIS diagnosed with pathology were selected. The diagnostic yield and the microcalcification characteristics of different grades DCIS with US, DM and US+DM were compared. Results Twenty patients had high-grade DCIS, 18 were low-intermediate-grade DCIS. Lesions in 28 patients were pure DCIS and 10 with microinvasion. The diagnostic yield for US to DCIS, high-grade DCIS, low-intermediate-grade DCIS was 73.68% (28/38), 90.00% (18/20) and 55.56% (10/18), respectively. The diagnostic yields for DM to DCIS, high-grade DCIS, low-intermediate-grade DCIS was 76.32% (29/38), 90.00% (18/20) and 61.11% (11/18), respectively. The diagnostic yield for US+DM to DCIS, high-grade DCIS, low-intermediate-grade DCIS was 78.95% (30/38), 90.00% (18/20), 66.67% (12/18), respectively. Detection yield of microcalcification on both US and DM was 57.89% (22/38). Conclusion The diagnostic yield and detection yield of microcalcification for US and DM to DCIS are similar, high-grade DCIS in diameter larger than 20 mm is associated with microinvasion and those smaller than 10 mm without microcalcification are often skipped over or misdiagnosed. |
