103 Background: While three prospective trials have demonstrated benefit from adjuvant radiation (XRT) after radical prostatectomy (RP) in patients with positive surgical margins (PSM), its use varies amongst physicians. Many rely on clinical acumen to determine the optimal strategy for application of XRT post RP. We aim to determine if the length of PSM and highest Gleason grade (GG) of tumor at the PSM (hGGPSM) can be used to identify patients at greatest risk of biochemical failure (BCF) post RP. Methods: A retrospective review of all RP patients at The University of Texas MD Anderson Cancer Center from 2002 to 2010 was performed. After a single pathologist review, patients with organ confined disease (pT2), pathologic N0/Nx and a PSM were included. BCF was defined as 2 sequential PSA values of ≥0.2 or any detectable PSA prompting XRT. Patients receiving adjuvant XRT or with <12 months follow-up were excluded. Results: 205 patients met the inclusion criteria. Median PSA was 5.3 ng/mL (0.5-33) and median follow-up was 64 months (13-130). The majority were low clinical stage (cT1c: 65%), low (11%)/intermediate (82%) grade and had a single site of a PSM (90%). BCF occurred in 47 patients for a 5 yr BCF free survival (BCFFS) of 69%. PSM length was significantly associated with BCFFS (≤1mm vs >1, p=0.02). When accounting for hGGPSM, Gl 3 tumors were less likely to experience BF (5 yr BCFFS-96%) regardless of PSM length, while BCFFS for Gl >3 tumors were significantly lower dependent upon length of PSM ( ≤1mm vs >1mm, p=0.03). On multivariable analysis length of PSM (p=0.05) and hGGPSM (p=0.007) remained independent predictors of BCF (Table). Conclusions: Length of PSM and hGGPSM are independent predictors of BCF. These should be considered when evaluating patients for adjuvant XRT and in risk stratifying patients in prospective clinical trials. [Table: see text]

128 Background: prostate brachytherapy at our institution was analyzed for implant quality on biochemical control. Methods: We treated 368 patients with clinically localized prostate cancer. All patients underwent 1 month CT based dosimetric analysis. Follow up data was available on 289 patients with a minimum follow up of 5 years. Gleason score was 6 in 80% (n=233), and 7 in 20% (n=56). Clinical stage was T1c in 90% of cases (n=260), T2a was 8% (n=23), T2b was <1% (n=3), T2c was < 1% (n=2). The initial prostate-specific antigen was < 10 ng/ml in 95% (n=274), 10.1-20 ng/ml in 5% (15).Patients with low risk disease ( clinical stage T1c, Gleason score 6 with a PSA < 10 ng/ml) n=228. Patients with intermediate risk disease Gleason 7 adenocarcinoma or with a PSA> 10 ng/ml < 20 ng/ml )n= 61. All patients were treated with I (125). All patients underwent a 1-month CT-based dosimetric analysis. The implant dose was defined as the dose delivered to 90% of the prostate volume on post implant dosimetry (D(90)). Results: At minimum follow up of 5 years overall freedom from biochemical failure was 91.4%. For Gleason grade 6 freedom from biochemical failure was 95%. For Gleason grade 7 freedom from biochemical failure was 77%. Based on PSA freedom from biochemical failure for PSA <10 ng/ml at diagnosis was 92 % and for PSA >10 ng/ml and <20 ng/ml was 80%. In patients with low risk disease ( clinical stage T1c, Gleason 6 adenocarcinoma with a PSA < 10ng/ml) the freedom from biochemical failure was 94%. In patients with intermediate risk disease (Gleason 7 adenocarcinoma or with a PSA >10 ng/ml <20 ng/ml ) freedom from biochemical failure was 84%. Patients with optimal dose implants n=264 freedom from biochemical failure was 95%. Patients with suboptimal dose implants n=25 freedom from biochemical failure was 52% Conclusions: With a minimum follow up of 5 years our data support the use of implant alone in low risk prostate cancer patients with a freedom from biochemical failure of 94%. Our data also shows the importance of implant quality in achieving optimal out comes.

4670 Background: As concerns mount regarding overtreatment and over-diagnosis of prostate cancer (CaP), active surveillance (AS) is increasingly utilized in low risk patients. While African-American (AA) race is associated with adverse outcomes after prostatectomy, its effect on patients managed with AS is not known. Methods: A retrospective review identified 222 patients managed with AS at the Duke Prostate Center from January 2005 to September 2011. All men had CaP diagnosed on biopsy performed at our center, and elected AS over treatment. Failure was defined as progression to treatment. In men who failed AS, the reasons for failure, follow-up PSA and biopsy characteristics were analyzed. The primary outcome - time from diagnosis to failure of AS for a reason other than patient choice - was analyzed with univariable and multivariable Cox proportional hazards models. Results: In our AS cohort, 73% are Caucasian and 23% AA. Median follow-up is 25.4 months. Age, household income, BMI, PSA, clinical stage, family history, prostate volume, number of cores with cancer, and Gleason grade on initial biopsy did not differ by race. The number of biopsies and PSA tests performed on AS did not differ by race. A higher proportion of AA men tended to fail from biopsy progression (72.7% vs. 63.8%) while a lower proportion failed by choice (9.1% vs. 14.9%) compared to Caucasians (p = 0.114). AA men had a significantly shorter time to failure (HR 1.74, p = 0.045) compared to Caucasians. There was a trend toward increased Gleason grade 8 or higher cancer on follow-up biopsy in AA compared to Caucasian men (10% vs. 2.5%, p = 0.08). AA race remained a predictor (HR 1.76, p = 0.058) of failure on multivariable analysis, as did initial PSA (HR 1.90, p = 0.031) and number of cores with cancer on initial biopsy (HR 1.29, p = 0.013). Conclusions: AA race was associated with higher risk for failure of AS. There was a trend toward AA men failing due to biopsy progression and with higher grade cancer. Additional follow-up is necessary to determine how this affects the long term outcomes of these men.

Background This study evaluates the association of adjuvant radiation therapy (RT) with improved locoregional (LR) recurrence for resected melanoma satellitosis and in-transit disease (ITD). Materials and Methods Data were collected retrospectively for resected melanoma satellitosis/ITD from 1996 to 2017. Results 99 patients were identified. 20 patients (20.2%) received adjuvant RT while 79 (79.8%) did not. Mean follow-up in the RT group was 4.3 years and 4.7 years in the non-RT group. 80% of patients who underwent RT suffered a complication, most commonly dermatitis. Locoregional recurrence occurred in 9 patients (45%) treated with adjuvant RT and 30 patients (38%) in the non-RT group ( P = 0.805). Median LR-DFS was 5.8 years in the RT group and 9.5 years in the non-RT group ( P = 0.604). On multivariable analysis, having a close or positive margin was the only independent predictor of LR-DFS (HR 3.8 95% CI 1.7-8.7). In-transit disease was associated with improved overall survival when compared to satellitosis (HR 0.260, 95% CI 0.08-0.82). Discussion The use of adjuvant RT is not associated with improved locoregional control in resected melanoma satellitosis or ITD. Close or positive margin was the only treatment-related factor associated with decreased LR-DFS after surgical resection of satellitosis/ITD.

PURPOSE: Although models exist that place patients into discrete groups at various risks for disease recurrence after surgery for prostate cancer, we know of no published work that combines pathologic factors to predict an individual's probability of disease recurrence. Because clinical stage and biopsy Gleason grade only approximate pathologic stage and Gleason grade in the prostatectomy specimen, prediction of prognosis should be more accurate when postoperative information is added to preoperative variables. Therefore, we developed a postoperative nomogram that allows more accurate prediction of probability for disease recurrence for patients who have received radical prostatectomy as treatment for prostate cancer, compared with the preoperative nomogram we previously published. PATIENTS AND METHODS: By Cox proportional hazards regression analysis, we modeled the clinical and pathologic data and disease follow-up for 996 men with clinical stage T1a-T3c NXM0 prostate cancer who were treated with radical prostatectomy by a single surgeon at our institution. Prognostic variables included pretreatment serum prostate-specific antigen level, specimen Gleason sum, prostatic capsular invasion, surgical margin status, seminal vesicle invasion, and lymph node status. Treatment failure was recorded when there was either clinical evidence of disease recurrence, a rising serum prostate-specific antigen level (two measurements of 0.4 ng/mL or greater and rising), or initiation of adjuvant therapy. Validation was performed on this set of men and a separate sample of 322 men from five other surgeons' practices from our institution. RESULTS: Cancer recurrence was noted in 189 of the 996 men, and the recurrence-free group had a median follow-up period of 37 months (range, 1 to 168 months). The 7-year recurrence-free probability for the cohort was 73% (95% confidence interval, 68% to 76%). The predictions from the nomogram appeared to be accurate and discriminating, with a validation sample area under the receiver operating characteristic curve (ie, a comparison of the predicted probability with the actual outcome) of 0.89. CONCLUSION: A postoperative nomogram has been developed that can be used to predict the 7-year probability of disease recurrence among men treated with radical prostatectomy.

15589 Background: We conducted a pilot adjuvant docetaxel and abbreviated androgen deprivation study (ADT) in patients with high-risk localized prostate cancer. Study objectives were to evaluate toxicity, feasibility of 6 months of ADT and 3 months of docetaxel treatment, and incidence of serum PSA relapse at 2 years compared to historical controls. Methods: Eligible patients had radical prostatectomy or radiation therapy for high-risk disease (pathologic node positive disease, capsule involvement, extra-capsular extension, seminal vesicle involvement, positive surgical margins, Gleason score = 8, clinical stage T2c or T3, serum PSA >20, or pre-op PSA > 15 plus any high-risk feature). Patients were treated with taxotere 35 mg/m2 weekly 3 out of every 4 weeks for 3 months, and an LHRH analog for 6 months concurrently. In this high-risk cohort, we estimated the risk of PSA recurrence to be as high as 65% in 2 years. To detect a reduction in recurrence rates after surgery or radiation by 40% at a power of 80% and a 2-sided alpha of 0.05, a total of 21 patients were needed in this pilot Phase II study. Results: Twentyone patients were enrolled between 9/04–9/05. The median age was 59.5 years (48–72). Ten patients had a radical prostatectomy and 11 had radiation therapy. All patients received 6 months of LHRH analog therapy. Median pre- treatment PSA was 9.5 ng/ml (4–120). Mean Gleason grade was 8 (7–9); 65% of the patients had >50% biopsies positive. Treatment was well tolerated. Acute toxicity included 1 grade IV hyperglycemia. There was 1 dose reduction and 1 treatment delay. One patient had grade III elevation in serum AST which was transient. Grade I/II toxicities were common and included fatigue, diarrhea, insomnia, and pedal edema. Median follow up is 20 months. Five patients have relapsed. One (of 11) patients treated with radiation has relapsed with metastatic bone disease at 9 months. Four (of 10) patients who underwent prostatectomy have had a serologic relapse at 14, 14, 17 and 21 months, respectively. Conclusions: These data suggest that adjuvant weekly taxotere with abbreviated course of ADT is feasible and well tolerated. In this pilot trial, at a median follow up of 20 months, 23% of patients have relapsed. Longer follow up is required and is ongoing. No significant financial relationships to disclose.

10 Background: Radiation therapy (RT) is commonly offered in the post radical prostatectomy (RP) setting, however response varies. We hypothesized that the genomic classifier ([GC] Decipher) score would predict biochemical failure (BF) and distant metastasis (DM) in men receiving post−RP RT. Methods: Under an institutional review board approved protocol, 223 men who underwent post−RP RT at the Kimmel Cancer Center of Thomas Jefferson University for pT3 or margin positive disease from 1990 to 2009 were identified. RNA was extracted from 143 patients with paraffin−embedded specimens and expression quantified from the highest Gleason grade tumor focus using a high−density oligonucleotide microarray. Excluding men who received neo−adjuvant therapy, 139 patients remained for GC calculation. Area under the receiver operating curve (AUC), decision curves, cumulative incidence accounting for competing risks, and multivariable Cox regression analyses were used to assess GC for predicting BF and DM after RT in comparison to nomograms. Results: The AUC of CAPRA-S was 0.67 (95% CI 0.58−0.77) and 0.65 (95% CI 0.44−0.86) for BF and DM, respectively. Integration of GC improved AUC to 0.75 (95% CI 0.66−0.84) and 0.77 (95% CI 0.64−0.91) for BF and DM, respectively. Cumulative incidence of BF at 8 years post-RT was 21%, 48%, and 81% for low (less than 0.4), intermediate (0.4 to 0.6), and high (more than 0.6) GC, respectively (p<0.00001). In multivariable analysis, patients who received RT early (pre−RT prostate-specific antigen [PSA] less than 1 ng/mL) had a BF benefit with a significantly reduced hazard ratio (HR) of 0.32 (95% CI 0.11−0.96, p<0.042). Patients with high GC had an HR of 14.73 for BF (95% CI 4.90−44.31, p<0.00001). Earlier PSA recurrence was observed in patients with high GC score that received salvage compared to adjuvant RT with median BF survival post-RT of 4.67 versus 8.78 years (p<0.04). This held true after adjusting for CAPRA-S score. Conclusions: This is the first validation of the GC in the post−RP RT setting. GC improved risk stratification above clinical classifiers. Patients with high GC received significant benefit from early RT intervention. For those patients with high pre-RT PSA and high GC, exploration of intensified therapy is warranted.

59 Background: To evaluate the pathological outcomes in patients who were suitable for Active Surveilance (AS) and underwent Radical Prostatectomy (RP) and to explore the potential predictive factors to identify Gleason upgrading and upstaging. Methods: A prospectively maintained database was used to evaluate 1,552 consecutive patients who underwent RP [Laparoscopic / Robotic] at our institution between 1998 and 2012. We identified 405 RP patients fulfilling the Memorial Sloan-Kettering Cancer Center criteria for AS (PSA ≤10 ng/ml, clinical stage ≤2a, Gleason≤6, ≤2 + cores and less 50% cancer in any one core). In the final RP specimen, upgrading was defined as identification of Gleason >6 and upstaging as presence of ≥ pT3. The clinical and the pathological features of upstaged/upgraded patients were compared with the remaining patients and the cox’s regression model was applied to identify potential predictors. Kaplan Meir curve was used to identify Biochemical Recurrence Free Survival (BCR-FS) at 5 years. Results: We noticed upstaging in 195 (48%) patients and Gleason upgrading in 55 (13%) at RP specimen. Multivariate analysis showed percent of positive core had significant association with upstaging/upgrading. Positive Surgical Margin (PSM) was noted in 66(16%) patients, and the PSM rate was significantly higher in upstaged patients. The mean follow-up of the study population was 28 months and the predicted BCR-FS at 5 years was 92% and 88% in the patients who were not and were upstaged/upgraded. Conclusions: Percentage of positive cores in patients subjected to Active Surveillance appears to predict pathological upstaging/upgrading at radical prostatectomy. [Table: see text]

2 Background: High risk localized Pca patients are more likely to relapse and suffer morbidity/mortality from metastatic disease after prostatectomy. Adjuvant ADT can reduce this risk. We hypothesized that MP in addition to two years of ADT could further reduce mortality from PCa. Methods: Participants with clinically localized (T1-T3, N0, M0) PCa received radical prostatectomy. Eligibility required ≥ 1 high risk criteria defined as Gleason sum ≥8; pT3b or pT4 or N1; Gleason 7 with positive margin; any one of these preoperative findings: PSA>15ng/ml, biopsy Gleason >7, biopsy Gleason >6 with PSA>10. ADT arm consisted of bicalutamide and goserelin for 2 years. ADT+MP arm received ADT plus 6 cycles of M 12mg/m2+ P 5mg BID. Primary endpoint was survival (OS). Median OS was anticipated to be 10 years in ADT arm requiring 680 patients/arm to detect a hazard ratio of 1.30 with 92% power and one-sided α=0.05. Results: S9921 enrolled patients from 10/99 to 1/07 when the DSMC recommended stopping due to increased incidence of leukemia in the ADT+MP arm. Of 983 patients randomized, 22 ineligible. 481 eligible on ADT and 480 on ADT+MP. Patients were stratified by stage (≤pT2, ≥pT3, N0 or N+), Gleason score, and intent to receive adjuvant radiation (RT) (Y/N). Median age was 60 years, 84% were white, presurgical PSA was 7.6 ng/ml, 16% had positive nodes, 26% intended to receive RT, 63% had positive margins. 11 ADT and 20 ADT+ MP received no protocol treatment. Median follow-up is 11.2 years. Conclusions: Survival was greater than anticipated in both arms. MP increases the risk of leukemia. There is no evidence that MP improves PCa specific survival when added to 2 years of adjuvant ADT. Clinical trial information: NCT00004124. [Table: see text]
