CDKN1B and posterior cortical atrophy: Genomic losses of tumor suppressor genes such as Cyclin Dependent Kinase Inhibitor 1B (CDKN1B), Phosphatase and Tensin Homolog (PTEN), Retinoblastoma Transcriptional Corepressor 1 (RB1), Tumor Protein P53 (TP53) and genomic gains of oncogenes like Cyclin D1 (CCND1), Fibroblast Growth Factor Receptor 1 (FGFR1), Myelocytomatosis (MYC) are frequently identified in primary PCa [10, 11].
