Intrinsic subtype concordance between extracranial tumors and brain metastases. Concordance of PAM50 inferred intrinsic subtypes in patients between matched a FFPE ECT and FFPE BrM (n = 10 patients), b FFPE BrM and Frozen BrM (n = 26), and c FFPE ECT, FFPE BrM, and Frozen BrM (n = 7). For the patient that contributed two ECT FFPE samples, only the ECT from breast tissue (PAM50 Normal) is considered in panels a and c; the other ECT sample was classified as HER2-Enr, matching the FFPE BrM from that patient. For the patient that contributed two FFPE BrM and two Frozen BrM, all samples were classified as Basal
