本文报告了我院从１９７９年１月～１９９４年５月检出本病１０例，占同期收治乳腺癌３３７例的２．７％。全组病例均行手术治疗。本病属临床可检出乳腺癌最早阶段，症状、体征较少，早期诊断有一定困难。本组误诊率达５０％。作者强调重视有乳腺癌危险因素的高危人群，注意发现乳房早期异常现象，经过Ｘ线摄片、乳导管造影、涂片细胞学检查等方法能检出更多的早期癌。从而提高乳腺癌的治愈率及生存率。 This article reports that 10 cases of this disease were detected in our hospital from January 1979 to May 1994, accounting for 2.7% of 337 cases of breast cancer treated in the same period. All groups of patients underwent surgical treatment. This disease is clinically detectable in the earliest stage of breast cancer, with fewer symptoms and signs, and it is difficult to diagnose early. The misdiagnosis rate in this group reached 50%. The authors emphasized the importance of high-risk groups with risk factors for breast cancer and noted that early abnormalities in the breasts were detected and that more early cancers could be detected by radiographs, ductal angiography, smear cytology, and other methods. In order to improve the cure rate and survival rate of breast cancer.
