Breast case - fractionation

79 year old with a 4.1 cm ER/PR +, Ki 67%, Her 2 (-) IDC with neuroendocrine features. Final path after lumpectomy pT2N0. 1/2 SLN"s had ITC's. One margin close at < 1mm but no tumor on ink. I met with her pre op and we were thinking 26 Gy in 5 WBRT. With that big of a tumor and close margin, would you boost on top of that or switch to 40 in 15 with boost? Or just leave it at 26 Gy in 5. She's in pretty good shape. Oncotype pending.
