Study on serum PSA determination and tissues pathology immunohis tochemistry

  Objective   The treatise reported the PSA levels in the sera of 526 asymptomatic men(over 50 years old), 16 men(age between 40-49)and 101 men(younger than 40years, control group)were determined.

  Methods   Ninety-three men whose serum PSAlevels were highere than 4.0 ng/ml were selected for biopsy.Tissues pathology analysis as well as PSA expression of prostatic tissues derived from biopsy were analyzed by methods of immuno histochemistry in biopsied men.

  Results   Prostatic hyperplasia was 81.08% in 40 case sample, prostatic cancer was 0.95%.

  Conclusions   The incidence rates of analysis benign prostatic hyperplasia was more than 60% and that of prostatic cancer was about 1% in men over 50 years old.
