To examine the distribution of total prostate-specific antigen (tPSA) and percentage of free/total PSA (%f/tPSA) values in patients undergoing prostate cancer screening in Canada.MethodsThe data from 4 consecutive annual prostate cancer screening events held in Montreal, Canada were examined with ...
Population-based Analysis of Normal Total PSA and Percentage of Free/Total PSA Values: Results From Screening Cohort To examine the distribution of total prostate-specific antigen (tPSA) and percentage of free/total PSA (%f/tPSA) values in patients undergoing prostate can... U Capitanio,P ...
Prostate-specific antigen, or PSA, is a protein produced by normal, as well as malignant, cells of the prostate gland. The PSA test measures the level of PSA in the blood. For this test, a blood sample is sent ...
Group II (normal DRE and tPSA between 10 and 20 ng/ml)--78 patients. Group III (suspicion DRE and sPSA between 2.5 and 20 ng/ml)--67 patients. For each group, the sensitivity, specificity and ROC curves were calculated for several cut-off values of the lPSA/tPSA ratio.Group I--...
Analysis of free to total PSA in serum following radiotherapy for prostate cancerIntroduction and Objectives The range of ''normal'' PSA values compatible with cure following radiotherapy (RT) for prostate cancer (PCa) has yet to be established. Various thresholds, ranging from 0.5 to 4.0 ug/L...
Aim of this study was to evaluate different decision strategies based on variations in the cut-off value of percent free PSA and in the range of total PSA values (reflex range) in which free PSA testing was applied. We compared these strategies to conventional total PSA testing by determining...
Phi test: The Prostate Health Index (PHI or Phi) combines three blood tests for prostate-specific antigen (PSA), total PSA, free PSA, and pro-PSA. These are different fractions of PSA antigens found in the blood. Experts believe that these values give a more accurate Phi score and better...
4, DCA was performed to compare the clinical utility of PSA, MRI, 68Ga-PSMA PET/CT and SUVmax-based prediction models in assisting prostate biopsy decisions at PSA values in the gray zone. The 68Ga-PSMA PET/CT and prediction models had comparable and obviously higher net benefits than the...
The positive predictive value for the Elecsys total PSA assay on the Elecsys 2010 analyzer was 0.390 using 4.0 ng/mL as a cutoff (malign Expected values prostate biopsy + tPSA 4.0 ng/mL: n = 336 / tPSA 4.0 ng/mL: n = 862). Expected values in normal healthy males Results for ...
Since the rs17632542 SNP is associated with poor survival, it is critical to carefully monitor men carrying either of the CT or CC genotypes as they may have aggressive cancer, without having abnormal total or f/t PSA values. The current study has several important strengths. The ...
