Under what circumstances would you offer adjuvant RT following breast-conserving surgery for borderline phyllodes tumors?
Do age or margins factor into your decision making? What dose and fractionation would you use?
Answer from: Radiation Oncologist at Community Practice
There is no definitive data, with some suggestion: all with borderline and malignant phylloides after BCT should be considered for RT (Dartmouth single arm study). In our practice, we offer for margin less than a cm, or if tumor is 5 cm and above after breast conserving surgery.
