Individualising radiotherapy for women with DCIS of the breast reduces recurrence after surgery San Antonio Breast Cancer Symposium (virtual SABCS 2020, 8-12 December, Texas, USA)

Ductal carcinoma in situ (DCIS) of the breast is characterised by abnormal cells in the milk ducts which have not spread into the breast tissue. An international study (BIG 3-07/TROG 07.01) shows that after breast conserving surgery, higher radiation doses to the part of the breast where the DCIS was found, in addition to radiotherapy of the whole breast, significantly reduced its risk of returning in patients with higher-risk DCIS. Compared to 5 weeks of whole breast radiotherapy, the study also shows that the shorter, more convenient 3 weeks of radiotherapy did not increase recurrence.
