Abstract

Purpose: We report the results of surgery in 520 patients with clinically localized carcinoma of the prostate (CAP) who received preoperative neoadjuvant hormonal therapy (NHT) for 3 to 11+ months. Methods: The results in the NHT patients were compared with those in 1413 men having surgery without NHT at our institution during the same time period. In the group without pretreatment, the median and mean follow-up was 36 and 21 months, respectively. In the patients receiving NHT, the median follow-up was 33 months and the mean 41 months. Results: The overall disease-free survival (DFS) rate (serum prostate specific antigen [PSA] concentration ≤0.2 ng/mL) was 75% at 5 years and 50% at 10 years. There was no statistically significant difference in overall DFS rate between men who had NHT and those who did not. No DFS advantage could be demonstrated for those patients with a presenting PSA >20 ng/mL who received NHT compared with patients with the same PSA concentration who did not receive NHT. Despite our previous experience indicating improved survival with NHT in men with a presenting PSA of > 10 ng/mL, we could find no advantage to NHT in enhancing DFS. At a median survival of 35 months (mean 41 months) in 201 men with an initial PSA ≥10 ng/mL, 70% had an undetectable PSA concentration at 5 years compared with 72% at the same time point in men presenting with PSA 1 disease had a significantly better DFS than those with either T2 or T3 CaP. However, within each stage, the addition of NHT to surgery did not result in a higher DFS rate. The 5- and 10-year DFS rates for stage T1 were 80% and 64%, for T2 disease 78% and 50%, and for T3 disease 67% and 50%. There was a statistically significant difference (P ≤ 0.003) in survival between stage T1 and stage T2 disease, but no significant difference in DFS was noted in patients presenting with stage T2 compared with T3 cancer (P = 0.431). Gleason score was not a significant predictor of durable DFS, and the addition of NHT did not improve the DFS within groups of patients with similar Gleason scores. Men with only one or two positive biopsy cores did significantly better than those with more than three positive cores (P = 0.06). There was a significant difference in DFS between men who had organ-confined disease and those with disease outside the gland (P = 0.0003). However, NHT did not improve DFS. The presence of positive surgical margins was a negative prognostic factor (P = 0.001). Men who received NHT had a statistically lower positive margin rate (P = 0.001), but NHT did not increase the likelihood of a durable DFS (P = 0.175). The duration of NHT did not affect the DFS (P = 0.100 for ≤3 v >3 months). Conclusion: There appears to be no subset of men undergoing radical prostatectomy in whom the routine administration of NHT is beneficial despite the statistically significant improvement in the pathologic findings.
