What is the appropriate nodal coverage a invasive ductal carcinoma status post lumpectomy with 50% or more of the SLN biopsied (for example, 2 of 4 SLN) showing micrometastases?   

Would you change your management based on receptor status (ER/PR+/HER2 neg vs triple neg) or menopausal status (pre vs post menopausal)? Would you treat whole breast alone, high tangents or add a 3rd SCV field?  Would a high risk Oncotype Dx score change your recommendation?
