Usefulness of the nadir value of serum prostate-specific antigen measured by an ultrasensitive assay as a predictor of biochemi
The objective of this study was to determine whether the nadir value of serum prostate-specific antigen (PSA) measured by an ultrasensitive assay could be a useful predictor of biochemical recurrence after radical prostatectomy for clinically localized prostate cancer. This study included 127 patients who underwent radical prostatectomy for clinically localized prostate cancer without neoadjuva...
متن کاملUltrasensitive assay of prostate-specific antigen used for early detection of prostate cancer relapse and estimation of tumor-doubling time after radical prostatectomy.
We used an ultrasensitive prostate-specific antigen (PSA) assay with a detection limit of 0.02 microgram/L for long-term monitoring of PSA changes in 5 patients who were cured by radical prostatectomy and in 10 patients who had failed prostatectomies; 5 patients who underwent cystoprostatectomy were also evaluated with one sample after surgery. Relapse-free periods, determined on the basis of c...
متن کاملRelapse and cure rates of prostate cancer patients after radical prostatectomy and 5 years of follow-up.
OBJECTIVES We have compared the ability of an ultrasensitive prostate specific antigen assay and a regular PSA assay to identify relapse and cure rates of prostate cancer patients after radical prostatectomy, during a 5-year follow-up period. DESIGN AND METHODS We measured PSA by an ultrasensitive assay (detection limit 0.001 ng/mL) and a conventional PSA assay (detection limit 0.1 ng/mL) in ...
متن کاملPrognostic significance of undetectable ultrasensitive prostate-specific antigen nadir after radical prostatectomy.
OBJECTIVES To investigate the prognostic significance of undetectable ultrasensitive prostate-specific antigen (PSA) nadir in patients who received radical prostatectomy (RP) for prostate cancer. METHODS We reviewed records of 384 patients who received RP for prostate cancer and were followed for at least 2 years with ultrasensitive PSA testing. Undetectable ultrasensitive PSA level was defin...
متن کاملDetection of prostate cancer relapse with prostate specific antigen monitoring at levels of 0.001 to 0.1 microG./L.
PURPOSE The development of prostate specific antigen (PSA) assays with detection limits of approximately 0.001 microgram./l. is technically feasible. We examined if serum PSA changes of 0.001 to 0.1 microgram./l. for up to 3 years after radical prostatectomy have any clinical value. MATERIALS AND METHODS We studied 148 patients with a postoperative PSA of less than 0.1 microgram./l. by a conv...
