目的探讨乳腺导管内癌的诊断特点。方法对1999年6月至2007年1月收治的77例导管内癌(ductal carcinoma in situ,DCIS)患者的诊断特点进行回顾性研究。结果乳管内视镜诊断病例数占总数的53.25%,其中20例乳腺摄影及B超检查均无恶性病变;57.14%的患者乳腺X线摄影检查提示为导管内癌,其中8例其他两种检查无恶性病变;23.38%的患者乳腺B超提示有可疑病变,其中3例其他检查无恶性病变。结论乳腺X线摄影、乳管内视镜和乳腺B超检查联合应用可提高乳腺导管内癌的诊断率。
Objective To investigate the diagnostic characteristics of intraductal carcinoma. Methods The diagnostic characteristics of 77 patients with ductal carcinoma in situ (DCIS) admitted from June 1999 to January 2007 were retrospectively studied. Results The number of cases diagnosed by endoscopy was 53.25%. There were no malignant lesions in 20 cases of mammography and B-mode ultrasound examination. The mammography examination in 57.14% of cases showed intraductal carcinoma. Eight of the other 8 cases No malignant lesions; 23.38% of patients with breast ultrasound B-suspicious lesions, of which 3 other tests without malignant lesions. Conclusion The combined application of mammography, endoscopy and breast ultrasound can improve the diagnostic rate of ductal carcinoma in the breast.
