Abstract: With the widespread adoption of screening mammography, the incidence of ductal carcinoma in situ (DCIS) has been dramatically increased. The spectrum of local treatment advances from mastectomy to breast conservation surgery plus whole breast irradiation (WBI), and hypofractionated WBI or accelerated partial breast irradiation. Although the efficacy of WBI on reducing local recurrence is clear, such benefit in the low-risk DCIS is still controversial. Further studies are required to establish a more precise local recurrence risk stratification system for better tailoring local treatment in patients with DCIS. In this review, the latest advances and controversies in surgery, radiation therapy and local recurrence risk stratification system for patients with DCIS were summarized.
