The ALU 260/111 copy number ratio showed a significant negative correlation with EEF1A2 and ESR1 copy number (ALU 260/111 vs. EEF1A2: −0.368, p-value = 0.02; ALU 260/111 vs. ESR1: −0.323, p-value = 0.04), which means that a decrease in the ALU 260/111 ratio was associated with an increase in EEF1A2 and ESR1 copy number (and thus with an increase in ccfDNA concentration) in the plasma of PCa patients. This evidence concerns the gene ESR1 and posterior cortical atrophy.
