CDH2 and benign prostatic hyperplasia: N‐cadherin expression was most frequent and strongest among CRPCs (median SI, 1; mean, 1.8) and skeletal metastases (median SI, 2; mean, 1.3) in contrast to localised cancers (median SI, 0; mean, 0.7) and non‐skeletal metastases (median SI, 0; mean, 0.5), and not observed in BPH (p < 0.0005).
