Prostate Specific Antigen Density Correlates With Features of Prostate Cancer Aggressiveness
Journal of Urology, 2007An increased prostate specific antigen density (serum prostate specific antigen divided by prostate volume) is an established parameter to help determine the need to perform prostate biopsies. A man with a high prostate specific antigen and a normal size prostate gland is more likely to have cancer than a man with the same prostate specific antigen and

To compare the performance of prostate-specific antigen (PSA) levels with the performance of PSA density (PSAD), the ratio of the serum to the size of the prostate, as predictors of the presence of prostate cancer.We analyzed the results of digital rectal examination (DRE), transrectal ultrasonography (TRUS), serum PSA levels, and PSAD in 244 patients ...

Prostate-specific antigen density: A new prognostic indicator for prostate cancer
International Journal of Radiation Oncology*Biology*Physics, 1993Prostate specific antigen density, previously described as a ratio of serum prostate specific antigen to the volume of the prostate, has been shown to be an important factor in the discrimination of patients with occult metastatic disease and patients with benign versus malignant prostatic disease.

Prostate specific antigen density in patients with histologically proven prostate carcinoma
Cancer, 1994Prostate specific antigen (PSA) does not appear to have the specificity to distinguish between benign prostate hyperplasia and cancer when the PSA is low. PSA density is thought by many to improve the specificity for cancer; however, this theory remains controversial.The authors retrospectively reviewed 220 carcinomas in radical prostatectomy specimens

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.

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 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

We examined the usefulness of measurements of free prostate specific antigen (PSA) and PSA density for predicting prostate cancer in men who had had a prior negative biopsy, a serum PSA level of 4.1 to 10.0 ng./ml. and benign findings on prostate examination.We measured percent free serum PSA and PSA density in 163 male volunteers age 50 years or older

We determined if prostate specific antigen (PSA) density and PSA slope alone or in combination could be used to predict which men with persistently elevated serum PSA and prior negative prostate biopsies will have prostate cancer on repeat evaluation.In our PSA-1 data base we identified 327 men 50 years old or older with an initially negative prostate ...
