Local treatment options for young women with ductal carcinoma in situ: A systematic review and meta-analysis comparing breast conserving surgery with or without adjuvant radiotherapy, and mastectomy.

Purpose: Young age is associated with poor prognosis in ductal carcinoma in situ (DCIS) of female breast and controversy exists regarding the optimal treatment modality for young patients. We aimed to compare treatment outcomes among breast conserving surgery (BCS), BCS with adjuvant radiotherapy (BCS + RT), and total mastectomy (MT) for young DCIS women.

Methods: PubMed, Cochrane, and Embase were searched for studies reporting comparative results among BCS, BCS + RT, or MT in ≤50 years old (y/o) DCIS females.
