Abstract

Authors investigated PSA concentration and preoperative prostate volume in 113 histologically proved BPH and 31 prostatic cancer patients. PSA concentration was measured with the Hybritech kit, the prostate volume by ultrasound with the help of an ellipse and calculated by computer. There was no correlation between the age of patients and volume of the prostate, whereas a correlation was proved between marker concentration and prostate volume (p<0.0001). The difference obtained by the correlation of the prostate volume and the PSA concentration ratio between the BPH and 31 tumorous patients (PSA density) was highly significant (0.143 vs. 0.699, p<0.001). The use of PSAD further improves the diagnostic value of PSA.
