Partial Breast Irradiation Effective Treatment Option for Low-Risk Breast Cancer
Partial breast irradiation produces similar long-term survival rates and risk for recurrence compared with whole breast irradiation for many women with low-risk, early stage breast cancer, according to new clinical data from a national clinical trial involving researchers from The Ohio State University Comprehensive Cancer Center.
This randomized, phase 3 study compared whole breast irradiation with partial breast irradiation in a large group of women with stage 0, 1 or 2 breast cancer. More than 4,200 patients were enrolled in the trial as part of NRG Oncology cooperative group clinical trial.
Study results showed that while partial breast irradiation does not produce equivalent cancer control for all breast cancer patients with stage 0, 1 and 2 disease, it should still be considered as an alternative for women with DCIS (ductal carcinoma in situ) and early stage breast cancers deemed "low risk," based on other tumor characteristics.
