| Biomarker | Methylation status of GSTP1 |
| Biomarker Basis | Methylation Based |
| Biomolecule | mRNA |
| Source | Tissue |
| Subjects | Humans |
| Regulation | Hypermethylated in Patients who relapsed |
| Odds Ratio/Hazard Ratio/Relative Risk | HR: 0.23 (95% CI: 0.09-0.64) |

| Type of Biomarker | Prognostic |
| Cohort | 74 patients who underwent radical prostatectomy for localised Prostate Cancer were chosen for the study. Over a period of 9 years 37 patients relapsed or died from recurrance. All the patients had a Gleason score of 7. |
