ReviewCurrent approach and future perspective for ductal carcinoma in situ of the breast.
Ductal carcinoma in situ (DCIS) has a good prognosis with the current treatment approach, with a 10-year breast cancer-specific survival rate of 97-98%. In ductal carcinoma in situ without micrometastasis, surgery and postoperative adjuvant therapy significantly improve local control, however it has been reported that the selection of the surgical procedure and adjuvant therapy does not influence breast cancer death. On the other hand, owing to widespread mammography screening, the frequency of early breast cancer detection has increased. ⋯ Recently, a non-surgery clinical trial for low-risk ductal carcinoma in situ was started. There is a possibility of achieving individualized treatment for ductal carcinoma in situ with less treatment intervention, without compromising the good prognosis obtained with the current treatment approach. This review presents an overview of the current treatment approaches, problems with overdiagnosis and potential future management strategies for ductal carcinoma in situ of the breast.
