There are also other newly discussed potential markers of CaP that may be useful in the diagnosis of progression of prostate cancer, which can be detected in urine, such as alpha-methylacyl-CoA racemase (AMACR) [19–21], which level is elevated in prostatic adenocarcinoma and high-grade intraepithelial neoplasia. This evidence concerns the gene AMACR and intraepithelial neoplasia.
