Radiation Boost Reduces Local Recurrence in DCIS Patients

A study presented last month at the American Society for Therapeutic Radiology and Oncology (ASTRO) meeting in Boston found that a boost of radiation therapy following lumpectomy in patients with ductal carcinoma in situ (DCIS) resulted in reduced rates of local recurrence.

The ipsilateral breast tumor recurrence–free survival in DCIS patients who received a radiation boost following whole breast radiation therapy experienced a reduction in local recurrence at 5 years (97.1% vs 96.3%), 10 years (94.1% vs 92.5%), and 15 years (91.6% vs 88%), with these differences achieving statistical significance (P = .013).
