The fPSA% varied by age, with men under 60 having a mean fPSA of 13.9% compared to 17.5% in men 60–69 years old and 19.8% in men over age 70. Significant associations of fPSA% with gland volume and PSA level were also observed. The sensitivity, specificity, and positive predictive ...
Prostate-specific antigen (PSA) levels by age remain the same across most populations. A PSA level above 4.0 ng/mL in any age group must be investigated.

Predictor Variables Age at the start of 2003 was categorized into 4 groups: 70 to 74 years, 75 to 79 years, 80 to 84 years and 85 years and older. Health status was defined by the Charlson Comorbidity Index, which is a summary measure of 19 chronic diseases selected and weighted accordin...
【10】In addition, various factors can cause someone’s PSA level tofluctuate. For example, the PSA level tends to increase with age, prostate gland size, and inflammation or infection. A recent prostate biopsy will al...
Calculations predicted that 209 000 men in each group would yield 1720 prostate cancer deaths during a median follow-up of 10 years, and allow a prostate cancer mortality RR of 0.87 to be detected with 80% power at a significance level of .05. Assuming an uptake in PSA testing of ...

The median follow-up period in the entire cohort was 33 months, and the median age at diagnosis was 71 years. The median PSA level at the time of diagnosis of nmCRPC was 3.3 ng/ml. Lymph node metastasis was positive in 17.3% of the patients. The number of patients treated with primary...
Whenever prostate health is affected, you may see an elevated level here. Infection, BPH (benign prostatic hyperplasia), enlargement of any kind, even age can also all cause a high PSA test score. So can an overly aggressive prostate massage. ...
