Application of serum PSA, fPSA detections and fPSA/PSA evaluation for diagnosis and therapy of prostatic diseases with DELFIA technique / 吉林大学学报(医学版)

ABSTRACT

Objective To investigate the application of PSA, fPSA concentrations and fPSA/PSA value for diagnosis and therapy of prostatic diseases detected with dissociation enhanced lauthanide fluoroimmunoassay (DELFIA) technique . Methods Thirty-four cases of normal individuals were used as control group, 46 patients with prostatitis as prostatitis group, 123 patients with prostatic hyperplasia as BPH group and 39 patients with prostate cancer as prostate cancer group. PSA, fPSA concentrations and fPSA/PSA value were detected with DELFIA technique. Results In prostate cancer group, the PSA and fPSA concentrations were significantly higher than those in other 3 groups (P0.05). Conclusion DELFI A technique is an effective method to improve the diagnosis and differential diagnosis of prostatic diseases, especially for prostate cancer.
