Table 7 shows that the detection of the GSTP1Ile/Ile-PON1/192RR-PON1/55LL-CYP17A2A2-GLO1CC or GSTP1Ile/Ile-PON1/192QQ-PON1/55LM-CYP17A1A2-GLO1CA or GSTP1Ile/Val-PON1/192QR-PON1/55MM-CYP17A1A1-GLO1AA genotype combination at individual level, might lead to the identification of patients with low, intermediate and high risk for PCa, respectively. A significant (p<0.05) association of the Low, Intermediate and High risk genotypes with the levels of ROS, GSH and MDA oxidative stress biomarkers in blood and cells from urine sediments was observed (Table 7). Here, PON1 is linked to posterior cortical atrophy.
