Preoperative and postoperative evaluation of prostate-specific antigen in localized prostatic cancer treated by...

Preoperative prostate-specific antigen (PSA) values were determined in 73 patients with clinically localized prostatic cancer and candidates for a radical procedure. Correlation of preoperative PSA with a final pathological stage was attempted. Only in 44.8% of our 22 patients with organ-confined disease was the PSA value within the normal range; in 17.3% of cases PSA values were higher than 20 ng/ml. 18.2% of the patients with locally advanced disease showed normal PSA values, while 45.5% had concentrations above 20 ng/ml. In the case of lymph node involvement, PSA values were normal in 22.7% of the cases. Our data indicate that no strict relationship can be suggested between PSA and the final pathological stage and grading of the tumor in patients who underwent radical prostatectomy.
