Therefore, in the present study, we investigated a range of preoperative MetS components, including body mass index (BMI), blood pressure, fasting glucose, high-density lipoprotein cholesterol (HDL) and triglycerides (TGs), as well as the preoperative serum PSA levels of patients with clinically localized PCa who received RP, particularly with respect to the link between these indicators and BCR after surgery. Here, KLK3 is linked to metabolic syndrome.
