Gene: SLN metastasis histopathology statusP
GSTP1
    Macro vs none<0.015
RAR-β2
    Macro vs micro<0.009
    Macro vs none<0.009
GSTP1 and/or RAR-β2
    Macro vs micro<0.018
    Macro vs none<0.002
  • NOTE. Macro, metastasis >2 mm; micro, metastasis <2 mm but >0.2 mm; none, no metastasis detected by H&E and immunohistochemistry.
