Further studies reported that GSTP1 methylation combined with other frequently methylated genes may be more helpful in assessing the prognosis of PCa patients, especially in mCRPC patients, such as the methylation of GSTP1 and RASSF2A [19] and the methylation of GSTP1, RASSF1, and RARB [18]. This evidence concerns the gene GSTP1 and posterior cortical atrophy.
