Irradiation after Surgery for Breast Cancer Patients with Primary Tumours and One to Three Positive Axillary Lymph Nodes: Yes or No?

Abstract

Our study identified several risk factors that correlated independently with a greater incidence of lrr and distant metastasis in patients with T1 and T2 breast cancer and 1-3 positive nodes. Patients with 0-2 risk factors may not be likely to benefit from post-mastectomy rt, but patients with 3-4 risk factors may need rt to optimize locoregional control and improve survival.
