Abstract

OBJECTIVE: To evaluate features and clinical outcome of patients with clinically localized prostate cancer graded pT0 following radical retropubic prostatectomy (RRP). STUDY DESIGN: Between 1974 and 2001 we performed 1,135 RRPs for cT1-T2 prostate cancer, of which 386 (34%) underwent 3-6 months of neoadjuvant endocrine treatment (NHT) before RRP. Median clinical follow-up was 53.8 months (range 24-252). Estimation of likelihood events for biochemical relapse was calculated according to the Kaplan-Meier method. Statistical differences between curves were calculated using the log-rank test. RESULTS: In 24 cases (2.12%) routine histologic workup failed to detect residual tumor. The pT0 group contained a higher proportion of cT1a-b patients and a biopsy Gleason score ≤ 6. A tendency toward lower preoperatory PSA levels in the pT0 group compared to the pT2-3 group was shown. PSA progression was observed in 3 pT0 patients, all of whom previously underwent NHT. CONCLUSION: Patients pTO at RRP presented with lower preoperative PSA values and low preoperative Gleason score compared to the pT+ group. Absence of tumor at pathology examination has a different clinical meaning when it occurs following NHT or in untreated patients. Patients pT0 after NHT may have a worse clinical outcome than pT0 untreated patients. © Science Printers and Publishers, Inc.
