RECURRENCE PATTERNS AFTER RADICAL RETROPUBIC PROSTATECTOMY: CLINICAL USEFULNESS OF PROSTATE SPECIFIC ANTIGEN DOUBLING TIMES AND LOG SLOPE PROSTATE SPECIFIC ANTIGEN

Abstract

After PSA became detectable PSA doubling time or, equivalently, log slope PSA, was a better indicator of the risk and time to clinical recurrence after radical retropubic prostatectomy than preoperative PSA, specimen Gleason sum or pathological stage. Hormone treatment may be targeted to patients at high risk for early metastatic clinical recurrence, appropriately timed radiation can be offered for proved local recurrence in those with long PSA doubling time and expectant treatment may be proposed for those with long PSA doubling time who remain clinically disease-free. Frequent and expensive imaging does not appear to be cost-effective in this latter group.
