J Clin Oncol. 2020 Jul 10;38(20):2230-2239. doi: 10.1200/JCO.19.02888. Other studies have shown that taking tamoxifen after lumpectomy for hormone-receptor-positive DCIS reduces the risk of both DCIS recurrence and invasive disease in both breasts. Unable to load your delegates due to an error After 10 to 20 years there is a significantly higher risk of up to 20% that patients develop a local relapse. Purpose: The NSABP (National Surgical Adjuvant Breast and Bowel Project) B-24 study demonstrated significant benefit with adjuvant tamoxifen in patients with ductal carcinoma in situ (DCIS) after lumpectomy and radiation. 2000;12(3):158-65. doi: 10.1053/clon.2000.9143.Cancer Manag Res. Still, no study has shown that radiation or tamoxifen after lumpectomy for DCIS improves overall survival or reduces the rate of metastatic recurrence (cancer coming back in a part of the body away from the breast).
