摘要乳腺导管原位癌又称导管内癌,属于乳腺癌前期病变,其治疗方式与乳腺癌治疗方式相似.由于乳腺导管原位癌患者的病死率较低,所以乳腺导管原位癌的治疗重点是提高患者的生命质量,但在其治疗方式上存在过度治疗现象.研究表明在乳腺导管原位癌的治疗上,保乳手术加放疗与乳房切除术的治疗效果一样,前哨淋巴结活检也可评价患者的腋窝状态;对于行保乳手术的乳腺导管原位癌患者来说,放疗和内分泌治疗可以降低同侧乳腺癌复发率,也成为乳腺导管原位癌的标准治疗.

abstractsDuctal carcinoma in situ belongs to the early stage of breast cancer.The treatment of ductal carcinoma in situ is similar with that of the breast cancer.Because of the low mortality rate in patients with ductal carcinoma in situ,there was an excessive treatment in the treatment of ductal carcinoma in situ.So the key to the treatment of ductal carcinoma in situ was to improve the quality of life.The present study shows that the effect of conserving surgery with radiotherapy is same with mastectomy's in the treatment of breast ductal carcinoma in situ.Sentinel lymph node biopsy can also be used to evaluate the patient's axillary status.For patients with ductal carcinoma in situ with breast conserving surgery,radiotherapy and endocrine therapy can reduce the recurrence rate of ipsilateral breast cancer.Radiotherapy and endocrine therapy have also become the standard treatment for ductal carcinoma in situ.
