Should regional nodes be included in whole breast RT for a favorable pT3N0 breast cancer after lumpectomy and SLNB?
Would patient age factor into your decision, such as a patient <30 or 40? If you would not give RNI for a favorable pT3N0, are there other risk factors you would consider where you would give RNI for pN0? What if the histology was mucinous?
Answer from: Radiation Oncologist at Academic Institution
I do not typically recommend RNI in a T3N0 following breast conserving surgery with negative SLN. While patient factors such as young age and pathologic factors ER-/Triple negative, LVSI concern me, they are not enough for me to offer RNI in a node negative patient.
