PDLIM5 and posterior cortical atrophy: Univariate analysis indicated that high PDLIM5 expression (HR =2.002, P=0.041), high PSA level (HR=2.107, P=0.026), Gleason score>7 (HR=3.388, P<0.001), high grade of N stage (HR=3.704, P=0.033) and Seminal Vesicle Invasion (HR = 3.825, P=0.001) were risk factors for BCR of PCa patients.
