The patient is an elderly female with a good KPS who presented with a cT2N1 triple-negative breast cancer.
The patient refused chemotherapy and immunotherapy (both pre and post surgery) and is now status post mastectomy and ALND (1/12 LN positive, 2 cm, no ECE), found to have pT2N1 disease (4 cm tumor, +LVSI, Grade 3) with widely negative surgical margins?
Would you offer PMRT in this case? Why or why not?
