Abstract

PURPOSE:

The independent clinical and pathological predictors of time to postoperative prostate specific antigen (PSA) failure were used to identify prostate cancer patients at high risk for this end point.

MATERIALS AND METHODS:

A Cox regression multivariate analysis was used to determine the prognostic significance of preoperative PSA, pathological stage, prostatectomy Gleason score and margin status in predicting the time to postoperative PSA failure in 862 men with palpable (T2) or PSA detected (T1c) prostate cancer. The 2-year PSA failure rates with 95% confidence intervals were calculated using the results of Cox regression analysis and a bootstrap procedure with 2,000 replications, respectively, and are presented in nomogram format stratified by preoperative PSA, pathological stage, prostatectomy Gleason score and margin status.

RESULTS:

Preoperative PSA (p = 0.0001), pathological stage (p< or =0.002), margin status (p = 0.0001) and prostatectomy Gleason score (p = 0.034) were independent predictors of time to postoperative PSA failure.

CONCLUSIONS:

Patients at high risk for early PSA failure could be identified postoperatively on the basis of preoperative PSA and prostatectomy pathology. Adjuvant therapy trials in these select patients may be justified.
