We developed a Prostate Cancer Urinary Epigenetic (ProCUrE) assay based on an optimal two-gene (HOXD3 and GSTP1) LASSO model, derived from methylation values in the training cohort, and assessed ProCUrE’s diagnostic and prognostic ability for prostate cancer in both the training and validation cohorts. This evidence concerns the gene HOXD3 and prostate carcinoma.
