We evaluated prospectively the ethnic variations in prostate specific antigen (PSA) and prostate specific antigen density in the detection of carcinoma of the prostate.A total of 297 consecutive patients with an elevated serum PSA and/or abnormal digital rectal examination underwent transrectal ultrasound with lesion directed and systematic biopsy (6 ...

Limited data exist on the relationship of percent free prostate specific antigen and prostate specific antigen density with prostate cancer prognosis. Therefore, we compared percent free prostate specific antigen and prostate specific antigen density with prostate specific antigen, Gleason sum and stage to predict prostate cancer prognosis in a large ...

Prostate specific antigen (PSA) has become an important method for early detection of prostate cancer. It has been suggested that prostate specific antigen density (PSAD) may be a more efficient test for early detection than PSA alone. A series of 327 men undergoing prostate biopsy were evaluated by PSA and PSAD.

To examine the efficacy of prostate-specific antigen (PSA) and prostate-specific antigen density (PSAD) in staging patients undergoing radical prostatectomy for clinically localized prostate cancer (CaP).Prostate gland volumes were estimated in patients with clinically localized CaP (n = 119) performing transrectal ultrasound and employing the prolate ...

To compare serum prostate-specific antigen (PSA) levels and PSA density (PSAD) among African American (AA), white, and Hispanic men with prostate cancer (PC) seen in an urban, equal-access urology clinic. Between January 1988 and January 1993, 1,105 men were screened for PC at Cook County Hospital in Chicago, Illinois.

Prostate-specific antigen (PSA) is the most accurate serum marker for cancer of the prostate (CaP). However, its sensitivity and specificity are suboptimal, especially at values ranging between 4.1 and 10.0 ng/ml (monoclonal), because benign prostatic hypertrophy and hyperplasia (BPH) and CaP frequently coexist in this range.

The results of 225 systematic prostate biopsies from 1992 to 1993 were evaluated retrospectively. The parameters prostate-specific antigen (PSA) density and age-specific PSA values were compared with digital rectal examination, transrectal ultrasound, and PSA as single parameters and possible combinations.

To determine the potential role of prostate-specific antigen (PSA) density (PSAD) in the early detection of prostate carcinoma if we apply age-specific PSA reference ranges (2.5 ng/mL or less for ages 40 to 49 years, 3.5 or less for ages 50 to 59, 4.5 or less for ages 60 to 69, and 6.5 or less for ages 70 to 79.We retrospectively reviewed 3234 cases ...

Prostate specific antigen (PSA) is an extremely valuable tumor marker. However, its use in detection is limited by its low positive and negative predictive values. The ability of serum PSA to distinguish between benign and malignant prostatic conditions is particularly poor in the intermediate range of 4.1 and 10 ng./ml. by the Hybritech assay. We used

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
