In a Thai FFPE cohort (MSP; PCa n = 62; BPH n = 81), SOX11 promoter methylation was more frequent in tumors than in benign samples (p < 0.001) [59] and was associated with the Gleason score, peri-neural invasion, and PSA level (p < 0.05) [60]. This evidence concerns the gene KLK3 and benign prostatic hyperplasia.
