Blood PSA testing is used as a screening test for prostate cancer. 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. However, PSA levels can spike in noncancerous conditions, such as ...
The median prostate-specific antigen (PSA) level at 5 years was 0.63 ng/mL -- a 90% reduction from the median PSA at baseline, reported Scott Eggener, MD, of the University of Chicago, during the Society of Urologic Oncologyopens in a new tab or window annual meeting. Biochemical recurre...
Both cPSA and tPSA levels were found to increase with age. The low tPSA and cPSA levels observed at the 95th percentile in men aged 40 to 59 years suggest that lower cutoff values should be used in place of the currently accepted tPSA level of 4 ng/mL. Lower cutoff values may help ...

9,11,12 Therefore, we conducted this study to determine PSA screening rates among elderly veterans stratified into subgroups based on age and a validated measure of health status that is strongly predictive of life expectancy. We examined VA data and Medicare claims for men aged 70 years or ...
复合PSA(cPSA,complexed PSA):血液中与多种内源性蛋白酶抑制物结合的PSA为cPSA,占血液中总PSA的60% ~ 90%。 PSA密度(PSAD,PSA density):血清PSA浓度(ug/L)与单位体积前列腺(cm3)的关系,以血清PSA值与前列腺体积(前列腺体积的...
There were 573 eligible practices (73%) that agreed to participate and there were 195 912 men eligible for the intervention group and 219 445 men eligible for the control group. Among these 415 357 randomized men (mean [SD] age, 59.0 [5.6] years), there were 189 386 in the ...
trials2,3 and Screening Trials4 showed that PSA testing results in reduced PCa-mortality but also leads to over-diagnosis emphasising the need to revise PSA-based screening for PCa to an individualised, risk stratified and informed decision-making model for men, especially at a younger age. PCa...
