PCA3 and posterior cortical atrophy: Serum miR−141, serum miR−375, and urine miR−141 showed AUC values of 0.800, 0.827, and 0.833 in differentiating PCa patients with GS = 6 and GS ≥ 8, respectively; serum miR−375 and urine miR−141 showed AUC values of 0.769 and 0.739 in differentiating patients with T1/T2 staging and those with T3/T4 staging, respectively; urine miR−141, miR−375, and PCA3 lncRNA achieved AUC values of 0.713, 0.709, and 0.705 in differentiating metastatic and non-metastatic patients, respectively (Figure 4D).
