Our three markers are not included in major commercial gene expression marker sets that predict breast tumor recurrence such as MammaPrint (70 markers) or Oncotype DX (16 markers) [40,41], although TGF β receptor II (TGFBR2) was among the initial set of 250 candidate genes considered by Oncotype DX. The gene discussed is TGFBR2; the disease is breast neoplasm.
