How long after surgery would you no longer offer PMRT for a patient who had pCR after neoadjuvant chemotherapy for stage IIB HER2+ breast cancer?
The patient was treated with neoadjuvant chemotherapy and had mastectomy with SLNBx about 6 months prior to being referred for adjuvant radiation.
Answer from: Radiation Oncologist at Community Practice
The value of PMRT in HER-2 positive stage II breast cancer with pCR is debatable, to begin with, and now with 6 months or more delay, I would favor no RT.
