Histopathological characteristics of radical prostatectomy specimen and long-term PSA changes in men with PSA levels of 4.0 ng/ml or less

Out of 132 prostate cancer (Pca) patients who underwent radical prostatectomy 31 (mean age 65 +/- 5 years) had prostate specific antigen (PSA) levels of 4.0 ng/ml or less (low PSA group). The average PSA level was 3.3 +/- 0.5 ng/ml in the low PSA group and 8.5 +/- 5.5 ng/ml in patients with a higher...

520 |a Out of 132 prostate cancer (Pca) patients who underwent radical prostatectomy 31 (mean age 65 +/- 5 years) had prostate specific antigen (PSA) levels of 4.0 ng/ml or less (low PSA group). The average PSA level was 3.3 +/- 0.5 ng/ml in the low PSA group and 8.5 +/- 5.5 ng/ml in patients with a higher PSA (high PSA group). The pT2 ratio of the radical prostatectomy specimens was 74% (23/31) in the low PSA group and 55% (55/101) in the high PSA group, pT3a was 16% (5/31) and 31% (31/101), pT3b was 10% (3/31) and 10% (10/101), pN1 was 0% and 5% (5/101), respectively. The digital rectal examination (DRE) gave a positive result significantly (p = 0.026) less frequently in the low PSA group (6/31 : 20%), than in the high PSA group (44/101 : 44%). However all three pT3b patients with a low PSA were positive in DRE. This suggests the importance of DRE to detect significant Pca with PSA < or = 4.0. PSA was measured at least three times for more than one year in 19 of the 31 patients with a low PSA level before diagnosis. In 14 of these 19 cases (74%), PSA velocity was more than 0.5 ng/ml/ year and PSA doubling time was less than 4 years. Some patients with significant Pca can not be detected with a PSA cutoff level at 4.0 ng/ml. We recommend that individuals have their own PSA levels, and that long-term changes of PSA are sometimes very important to detect cases of Pca with lower PSA
