PURPOSE: To identify factors predictive of local recurrence as defined by a complete response to salvage radiation therapy in patients whose disease recurs after radical prostatectomy. PATIENTS AND METHODS: Ninety-five patients with recurrence after radical prostatectomy who were evaluated by prostatic fossa biopsies, and a subset of 49 of these patients treated with radiation for control of presumed or biopsy-proven local recurrence, were studied. RESULTS: Biopsies were positive in 40 (42%) of the 95 biopsied patients. Multivariate analysis revealed that prebiopsy prostate-specific antigen (PSA) level, postrecurrence PSA doubling time, and positive digital rectal examination (DRE) of the prostatic fossa were all statistically significant predictors of a positive biopsy. For the 49 patients subsequently treated with salvage radiation therapy, the overall actuarial 3- and 5-year PSA relapse-free probabilities were 43% and 24%, respectively. Univariate analysis showed no differences in the PSA relapse-free probabilities associated with any pathologic features of the radical prostatectomy specimen, biopsy confirmation of local recurrence, or DRE of the prostatic fossa. In multivariate analysis, controlling for all other variables, preradiation PSA and postrecurrence PSA doubling time measured before radiation were the only statistically significant predictors of outcome. CONCLUSION: DRE of the prostatic fossa, prebiopsy PSA, and postrecurrence PSA doubling time predict which patients will have biopsy-proven local recurrence. However, response to salvage radiation therapy is associated with postrecurrence PSA doubling time and with preradiation PSA level only. DRE of the prostatic fossa and biopsy confirmation of local recurrence are not associated with salvage radiation outcome.

4568 Background: Among patients treated with radical prostatectomy (RP) with a PSA recurrence, we previously found men with a PSA doubling time (PSADT) <3 months were at increased risk of prostate cancer death, though these men constituted a small subset of patients. We sought to determine the actual and predicted number of prostate cancer deaths stratified by PSADT. Methods: We retrospectively studied 379 men treated with RP between 1982 and 2000 with a PSA recurrence. We calculated the actual and 15-year actuarial number of prostate cancer deaths in each of the following PSADT categories: <3, 3.0–8.9, 9.0–14.9, and ≥15.0 months. Results: Median follow-up after PSA recurrence was 7 years. During this time, there were 76 prostate cancer deaths; the majority (51%) were among men with a PSADT of 3.0–8.9 months. Though men with a PSADT <3 months were at the greatest risk of death, this group accounted for only 20% (n=15) of all prostate cancer deaths. Using actuarial 15-year estimates of prostate cancer specific survival, 50% of all prostate cancer deaths were among men with a PSADT of 3.0–8.9 months while men with a PSADT <3 months accounted for only 13% of prostate cancer deaths. Using actuarial 15-year estimates of all-cause and prostate cancer specific mortality, among men with a PSADT <15 months, prostate cancer was estimated to be the cause of death in 94% (145/155). Only among men with a PSADT >15 months was the risk of competing causes of mortality high enough such that the majority of deaths were not attributed to prostate cancer. Conclusions: Among a select cohort of men treated with RP who experienced a PSA recurrence, prostate cancer was estimated to account for 75% of all deaths. Though men with a PSADT <3 months were at the greatest risk, the majority of deaths occurred among men with a PSADT of 3.0–8.9 months. Efforts to reduce prostate cancer mortality should focus on men with intermediate PSADT times (3.0–15.0 months) as they represent the greatest public health concern among men with PSA recurrence following RP.

The Impact

167 Background: Short PSA doubling time (PSADT) after biochemical recurrence (BR) post radical prostatectomy (RP) is known to predict worse outcomes following salvage external beam radiation therapy (SRT). The ideal PSADT cut-off, however, in this context remains uncertain. In this study, we sought to identify the best PSADT cut-off for predicting clinical outcomes following SRT for BR after RP. Methods: 575 patients who received SRT at a single institution for BR after RP were retrospectively reviewed in an IRB approved analysis. The impact of PSADT on biochemical failure (BF), distant metastasis (DM), prostate cancer-specific mortality (PCSM), and overall survival (OS) was assessed using Kaplan-Meier and Cox Proportional Hazards models. Results: Median follow up was 56.7 months post SRT. PSADTs could be calculated for 277 patients. PSADT strongly predicted BF, DM, PCSM, and OS on univariate analysis regardless of cut-off point. There was no statistical difference in BF, DM, PCSM, or OS between patients with PSADT <3 (n=40) and 3-6 months (n=61) or between 6-10 (n=62) and >10 months (n=114). A difference existed in BF (p<0.01 HR: 2.2 [95%CI: 1.4-3.5]) and DM (p=0.02 HR: 2.2 [95%CI: 1.2-4.3]) between PSADT of 3-6 and 6-10 months. PSADT ≤6 had the largest positive predictive value (PPV) for BF (70%), DM (36%), and PCSM (13%) at 5 years. There was no difference in negative predictive value between a PSADT >10 vs. >6 months for BF, DM, PCSM, and OS with 5 year rates of (60% vs. 60%, 86% vs. 86%, 99% vs. 98%, and 95 vs. 94% respectively). On multivariate analysis PSADT ≤6 was a strong predictor of BF (p<0.01 HR: 2.1 [95%CI: 1.5-3.0]), DM (p=0.01 HR: 2.0 [95%CI: 1.2-3.4]), and PCSM (p=0.04 HR: 2.3 [95%CI: 1.1-5.2]), with a trend towards predicting OS (p=0.12 HR: 1.5 [95%CI: 0.9-2.6]). Conclusions: A PSADT ≤6 months was the best predictor of outcomes in our data set, particularly for DM and PCSM. Currently, the most common predictive nomogram for SRT uses PSADT <10 months as the cut-off point for BF. These results suggest that using a PSADT of ≤6 months may improve the ability to predict clinically significant outcomes and hence identify men who may benefit from additional therapy.
