  1. ER, estrogen receptor; PR, progesterone receptor; AR, androgen receptor; APC, adenomatosis polyposis coli.
  2. aImmunostain scoring: 0 = no or only exceptionally rare positive nuclei; 1 = 1–25% positive nuclei, 2 = 26–50% positive nuclei, 3 = 51–75% positive nuclei, 4 = 76%–100% positive nuclei; d = diffuse staining; p = patchy staining.
