Popis: | A study was performed on 290 men to compare the level of serum prostate-specific antigen (PSA) in controls, patients with benign prostatic hyperplasia (BPH) and patients with prostatic cancer. The upper limit of normal was 5.0 micrograms/l as determined in 110 elderly hospitalized males (mean age 62 years) without urological complaints. Of the 106 patients with BPH, 33% had raised values above 5.0 micrograms/l. Values above 10 micrograms/l were found in 18 BPH patients. A positive correlation was found between prostate volume (grams of tissue removed during transurethral resection) and preoperative PSA levels (r = 0.55, n = 106, p less than 0.001). PSA levels above 10 micrograms/l were found in 4% of BPH patients with a prostate volume of less than 20 g (n = 54), in contrast with 45% of patients with a prostate volume above 40 g (n = 20). The sensitivity of this PSA assay (cutoff level 10 micrograms/l) as established in 74 prostate carcinoma patients was 31% for category T0 (n = 13), 56% for category T1-2 (n = 16), 75% for category T3-4 (n = 20) and 100% for category M1 or N1-4 (n = 25). In an earlier study prostatic acid phosphatase (PAP) was measured in these same samples. PSA appeared to be much more sensitive than PAP. Seventeen of the 74 prostatic carcinoma patients (23%) had normal PAP levels but their PSA values were raised above 10 micrograms/l, while in only 2 patients an increased PAP level was combined with a normal PSA.(ABSTRACT TRUNCATED AT 250 WORDS) |
