RHOU and posterior cortical atrophy: When the two large groups of RP samples (benign RP-B and malignant RP-PCa) were compared with each other, most of the differences were statistically still highly significant (p≤0.001), except for RHOU, LMNB1 and PLA2G7, indicating the stronger impact of detectable cancer tissue on biomarker expression patterns compared to likely field effects.
