Core Concepts
Regional nodal irradiation did not improve invasive disease-free survival in low-risk breast cancer patients.
Stats
"At 5 years, the cumulative incidence of LRR was 0.85% among women who had breast-conserving surgery plus radiotherapy with RNI; 0.55% after breast-conserving surgery with radiotherapy without RNI; 0.11% after mastectomy followed by radiotherapy; and 1.7% after mastectomy without radiotherapy."
"Invasive disease-free survival did not differ by RNI receipt (premenopausal hazard ratio [HR], 1.03; P = .87; postmenopausal HR, 0.85; P = .16)."
Quotes
"The incidence of locoregional recurrence observed in this study was reassuringly low."
"Disease-free survival was not associated with RNI receipt."
