What would be your approach to first line therapy for patient with metastatic HER2 positive breast cancer with CHF (LVEF <50%)?
Is there absolute LVEF threshold you would not use HER2 targeted therapies?
Answer from: Medical Oncologist at Community Practice
I would have cardiology on board and see if EF can be improved with medication. If close to 50% and cardiology feels it's stable/can be improved and can be closely monitored, I may go ahead after coordination with them.
