Variation of serum PSA with age in benign prostatic hyperplasia patients / 中华泌尿外科杂志

ABSTRACT

Objective To establish age specific reference ranges of serum total prostatic specific antigen (T PSA) and to investigate the relationship between T PSA,free PSA (F PSA) and ratio of F PSA/T PSA(F/T) with age in benign prostatic hyperplasia (BPH) patients. Methods 913 consecutive cases were studied retrospectively.In all of them with the age ranged from 30 to 89, serum T PSA and F PSA levels were assayed.All the patients were suspected to be BPH or PCa,103 being diagnosed as PCa on biopsy under B ultrasound and the other 810 being BPH. Results The incidence rate of PCa was 11.3% in this group.Serum T PSA and F PSA levels were positively correlated with the age ( r=0.22,P
