Correlation between the complex PSA/total PSA ratio and the free PSA/total PSA ratio, sensitivity and specificity of both markers for the diagnosis of prostate cancer.
OBJECTIVE To compare the behaviour of the PSAcomplex/PSAtotal percentage (PSAc%) against the PSA free/PSA total (PSAl%) and analyse both markers for their usefulness in diagnosing prostate cancer. MATERIAL AND METHODS We measured total PSA (PSAt), free PSA (PSAl), complex PSA (PSAc), PSAl% and PSAc% levels in 158 patients. Of these, 98 (62%) were biopsied for presenting PSAt≥3 ng/dl and PSAl%...
متن کاملThe significance of TPSA, free to total PSA ratio and PSA density in prostate carcinoma diagnostics.
Prostate-specific antigen (PSA) is the one of the most valuable tumor markers for the early detection and management of prostate carcinoma, but not an ideal one because of poor specificity in the case of prostatic hypertrophy and other benign conditions. In order to overcome this drawback some other parameters as is free to total ratio (F/T) PSA and PSA density (PSAD) are introduced. It has bee...
متن کاملRole of Serum Total PSA (Prostate Specific Antigen) and Free to Total PSA Ratio in the Diagnosis of Carcinoma Prostate
The objective of the study was to evaluate and compare the role of total and free/total ratio of serum prostate specific antigen level in diagnosing carcinoma prostate. A cross sectional study was conducted at the Department of Biochemistry, Dhaka Medical College (DMC) with collaboration of the Department of Urology, Dhaka Medical College Hospital (DMCH), Dhaka from July 2008 to June 2009. This...
متن کاملThe preoperative serum ratio of total prostate specific antigen (PSA) to free testosterone (FT), PSA/FT index ratio, and prostate cancer. Results in 220 patients undergoing radical prostatectomy.
OBJECTIVES To evaluate associations of preoperative total prostate specific antigen (PSA) to free testosterone (FT), the PSA/FT index ratio, with features of pathology prostate cancer (PCA) and to investigate its prognostic potential in clustering the PCA population. PATIENTS AND METHODS After excluding criteria, the records of 220 patients who underwent radical prostatectomy (RP) were retros...
متن کاملRatio of free or complexed prostate-specific antigen (PSA) to total PSA: which ratio improves differentiation between benign prostatic hyperplasia and prostate cancer?
BACKGROUND The aim of this study was to compare the diagnostic utility of a new assay that measures all forms of prostate-specific antigen complexed (cPSA) to serum proteins except alpha(2)-macroglobulin with the assay of free PSA (fPSA) and the corresponding ratios to total PSA (tPSA) to improve the differentiation between benign prostatic hyperplasia (BPH) and prostate cancer (PCa). METHODS...
