Would you give chemotherapy and trastuzumab to a patient with multifocal high grade, microscopic (<5mm) HR-, HER2+ IDC embedded in extensive DCIS, staged as pTis pT1a(m) N0?
Answer from: Medical Oncologist at Community Practice
The data is limited, especially in extensive high grade DCIS with microinvasion that is HER2 positive and the decision must build on the balance of benefit vs risk of treatment.In extensive DCIS with multifocal T1a as described in this question, I don't hesitate in recommending adjuvant chemotherapy...
