Would you offer adjuvant radiation to a woman with a history of mastectomy and reconstruction for DCIS (no prior RT) who develops a cT1cN0 new primary IDC in the chest wall?
The IDC was felt to be a new primary arising from residual breast tissue given it was over 10 years from her initial DCIS.
Answer from: Radiation Oncologist at Community Practice
I would usually treat this recurrent/new primary with PMRT.
