The disappearance pattern of prostate-specific antigen from serum after a standard radical prostatectomy was studied in eight patients with cancer confined to the prostate. The results were used to plot an elimination curve and calculate the best fit. A biphasic pattern was found with an average biological half-life of 1.63 hours in the alpha-phase, and 4.63 days in the beta-phase. Based on these results it is concluded that determination of prostate-specific antigen concentrations less than one month after a standard radical prostato-vesiculectomy has no value for the detection or exclusion of residual malignant processes.

D008875	Middle Aged	An adult aged 45 - 64 years.	Middle Age
D011468	Prostatectomy	Complete or partial surgical removal of the prostate. Three primary approaches are commonly employed: suprapubic - removal through an incision above the pubis and through the urinary bladder; retropubic - as for suprapubic but without entering the urinary bladder; and transurethral (TRANSURETHRAL RESECTION OF PROSTATE).

D014408	Biomarkers, Tumor	Molecular products metabolized and secreted by neoplastic tissue and characterized biochemically in cells or BODY FLUIDS. They are indicators of tumor stage and grade as well as useful for monitoring responses to treatment and predicting recurrence. Many chemical groups are represented including HORMONES; ANTIGENS; amino and NUCLEIC ACIDS; ENZYMES; POLYAMINES; and specific CELL MEMBRANE PROTEINS and LIPIDS.
