Introduction: Prostatic specific antigen (PSA) is an excellent tumor marker, but it is not specific for prostate cancer. We evaluated the accuracy of PSA adjusted for transition zone volume calculated by transrectal ultrasonography in predicting prostate cancer in men compared with PSA density. Material and Methods: PSA adjusted for transition zone volume was obtained from 100 patients who u...

conclusions psa, psa density, and gleason score should be considered together in order to more accurately predict the adverse pathologic features of prostate cancer. methods we conducted a cross-sectional study of 105 patients with localized prostate cancer who underwent radical prostatectomy between 2006 and 2013. we recorded gleason scores and psa levels, in addition to the results of patholo...

Background: It is relevant to highlight that there is not a precise and perfect report on either 95 percentile value (upper limit of normal range) or on appropriate reference intervals for serum PSA in Iranian population. Objective: To determine age-specific reference ranges for serum prostate-specific antigen (PSA) concentration and PSA density (PSAD) and prostate volumes in a population of he...

OBJECTIVES To address health disparities in risk stratification of U.S. Hispanic/Latino men by characterizing influences of prostate weight, body mass index, and race/ethnicity on the correlation of PSA derivatives with Gleason score 6 (Grade Group 1) tumor volume in a diverse cohort. RESULTS Using published PSA density and PSA mass density cutoff values, men with higher body mass indices and...

conclusions using tzpsad as an adjunct to psa may improve the specificity of psa in the diagnosis of pca and decrease the number of unnecessary prostatic biopsies in iranian men with serum psa level < 20 ng/ml. results among 1120 men who were eligible for enrolment, prostate cancer was detected in 265 patients. mean serum psa levels were 9.7 ± 4.3 ng/ml and 8.5 ± 3.7 ng/ml in patients with and ...

We examined the usefulness of prostate specific antigen alph-1-antichymotrypsin complex (PSA-ACT) and its indices for the detection of prostate cancer in patients with a prostate specific antigen (PSA) level between 2.1 and 10.0 ng/ml. Between July 1999 and October 2001, 151 patients with a PSA level between 2.1 and 10.0 ng/ml underwent a systematic biopsy under transrectal ultrasound (TRUS) gu...
