Brief Summary
The effect of internal mammary irradiation (IMI) added to whole-breast or thoracic-wall irradiation plus supraclavicular (SVC) irradiation after surgery on survival among women with early-stage intermediate risk (N1) breast cancer remains debated. The present study aimed to identified patient could be omitted from internal mammary lymph node irradiation by using a clinical-genomic model.

Interventions
clincial high risk breast (≥2 risk factors)patients with 18-gene low risk an indication for regional nodal irradiation will received 2 Gy for 25 fractions to chest wall or whole breast and supraclavicular lymph nodes irradiation and sequential tumor bed boost of 2 Gy for 5 fractions following breast conserving surgery.
