APOA1 and posterior cortical atrophy: In this study we investigated a range of preoperative blood lipid profiles, TC, HDL, triglyceride (TG), apolipoprotein A1 (apoA1), and apolipoprotein B (apoB), as well as the specific ratio of these markers (TC/HDL, LDL/HDL and apoB/apoA1) of patients with clinically localized PCa who underwent radical prostatectomy (RP), particularly with respect to the relationship between these markers and biochemical recurrence (BCR) after surgery.
