2. Figure 1
PITX2 promoter methylation in matched tissue samples [prostate cancer (PCa), normal adjacent tissue (NAT), benign prostatic hyperplasia (BPH)] from 24 patients with PCa. PITX2 methylation reliably discriminates between tumor and normal or hyperplastic tissue. The gray line indicates median methylation. n = 22 (BPH); n = 24 (PCa and NAT). P < 0.001 (analysis of variance between groups PCa, NAT, and BPH; Kruskal-Wallis test).

3. Figure 2
Kaplan-Meier analysis of biochemical recurrence (BRC)–free survival in 260 patients with prostate cancer stratified by PITX2 methylation status. Patient classification into PITX2 low and PITX2 high groups was based on a previously well-established cut-off (6.43% methylation).23 Approximate mean BCR-free survival was 120 months (PITX2 low; 95% CI, 112–128 months) and 111 months (PITX2 high; 95% CI, 101–121 months), respectively. n = 138 (PITX2 low); n = 122 (PITX2 high). P = 0.043 (log-rank test).

4. Figure 3
PITX2 methylation in prostate biopsy samples from patients with prostate cancer (PCa) and benign prostatic disease (BPD). PITX2 methylation was significantly increased in tumor-positive biopsies of patients with PCa compared with tumor-negative cores of patients with PCa or BPD tissue (P < 0.001). Furthermore, there was a slight but significant difference between biopsy samples from patients with BPD and tumor-negative samples of patients with PCa. Light gray lines represent median methylation. n = 32 (PCa); n = 31 (BPD). P < 0.05(Kruskal-Wallis test).
