116 Background: This year, the Surveillance, Epidemiology, and End Results (SEER) database released individual patient clinical Gleason score (GS) at the time of biopsy/transurethral resection of the prostate (TURP), which, along with the previously available clinical stage and prostate-specific antigen (PSA), allows a unique opportunity to study the clinical presentation and treatment selection of prostate cancer in the US. Methods: The SEER database was used to identify men diagnosed with localized prostate cancer in 2010 who were then assigned National Comprehensive Cancer Network (NCCN) risk group based on clinical factors at diagnosis. We determined sociodemographic factors associated with having high-risk disease and analyzed the impact of NCCN risk, along with sociodemographic factors, on local treatment selection. Results: A total of 42,403 men were identified of which 16,171 (38%) had low-risk, 16,990 (40%) had intermediate-risk, and 9,242 (22%) had high-risk disease. Older, non-white, and non-married patients living in counties with higher poverty rates, were most likely to be diagnosed with high-risk disease on multivariable analysis. Of the 38,634 men for whom prostate cancer was the first malignancy, 8,832 (23%) had no local treatment, 15,421 (40%) had prostatectomy, 13,855 (36%) had radiation treatment (including external beam radiation and/or brachytherapy), and 526 (1%) had another form of local tumor destruction (predominantly cryotherapy). In total, 29% of low-risk, 16% of intermediate-risk, and 25% of high-risk patients received no local treatment (p < 0.001). On multivariable analysis, older, non-white, and non-married patients living in counties with higher poverty rates who had low-risk disease, were least likely to receive local treatment. Conclusions: Our analysis provides information regarding the current clinical presentation and treatment of localized prostate cancer in the US. We note persistent disparities in the presentation and treatment of prostate cancer according to sociodemographic factors and potential under treatment of high-risk disease.

Background. The CHAARTED and LATITUDE trials demonstrated a prolonged overall survival (OS) for metastatic hormone-naïve prostate cancer (mHNPC) patients who receive up-front docetaxel or abiraterone acetate. These studies used their own risk criteria: CHAARTED trial defines high- and low-volume diseases and LATITUDE trial targeting a high-risk disease. The present study explored whether or not the CHAARTED and LATITUDE criteria were useful for predicting the outcome in Japanese bone mHNPC patients, including elderly patients (≥70 years). Methods. A total of 532 mHNPC patients diagnosed from 2004 to 2014 in multithird referral cancer centers were enrolled in this study. All patients had bone metastasis and received combined androgen blockade treatment as an initial hormonal therapy. Results. The number of patients with CHAARTED low-volume and high-volume diseases was 178 (33.5%) and 354 (66.5%), respectively. On the contrary, the number of patients with LATITUDE low-risk and high-risk diseases was 157 (29.5%) and 375 (70.5%), respectively. A total of 307 (57.7%) patients were defined as having both CHAARTED high-volume and LATITUDE high-risk disease. The median castration-resistant prostate cancer- (CRPC-) free survival was 12.5 months for the CHAARTED high volume, 56.9 months for the CHAARTED low volume, 13.6 months for the LATITUDE high risk, and 37.3 months for the LATITUDE low risk, respectively. The OS was 50.1 months in patients with CHAARTED high-volume disease, 95.1 months in patients with CHAARTED low-volume disease, 54.0 months in patients with LATITUDE high-risk disease, and 92.7 months in patients with LATITUDE low-risk disease, respectively. This trend was also observed in elderly (≥70 years old) patients. Conclusions. The patients with CHAARTED high-volume disease or LATITUDE high-risk disease showed a shorter CRPC-free survival and a shorter OS than those in the CHAARTED low-volume disease group or in the LATITUDE low-risk group among Asian Japanese bone metastatic HNPC patients.

5126 Background: We aimed to characterize and quantify variation in the primary management of localized prostate cancer at the level of clinical practice sites. Methods: Data were abstracted from patients accrued to the CaPSURE national prostate cancer registry. Patients were accrued from the 36 clinical practice sites which contributed at least 30 patients to the registry, and represented all those diagnosed since 1990 with localized disease who received radical prostatectomy (RP), external beam radiation therapy (EBRT), brachytherapy, active surveillance / watchful waiting (WW), or primary androgen deprivation therapy (PADT) were included. Descriptive analyses were performed, and a random effects logit hierarchical model was constructed, controlling for year of diagnosis, age, comorbidity, PSA, Gleason score, clinical T stage, and percent of biopsy cores positive, to estimate the proportion of variation in primary treatment selection explicable by practice site. Analyses were conducted for all patients and for low-risk patients (Gleason score ≤6, PSA ≤10 ng/ml, clinical stage ≤T2a). Results: 10,080 men were analyzed. The distribution among primary treatments at each clinical practice site varied widely: use of RP, for example, ranged from 12% to 95% of enrolled patients. Patterns of treatment are not reliably explained by patient risk distribution at each site. The proportion of variation attributable to clinical practice sites was 10% for PADT, 19% for WW, 21% for EBRT, 28% for RP, 37% for brachytherapy, and 75% for cryotherapy. For low-risk patients only, this proportion was higher for all treatment types except brachytherapy and cryotherapy. Only a small amount of the variation attributable to practice site can be explained by measured sociodemographic factors such as ethnicity, income, education, and geographic region. There are significant trends in treatments over time, including more use of PADT for intermediate- and high-risk patients, and more use of RP and WW for low-risk patients. Conclusions: These data do not represent a random sampling of the United States population. However, the significant variation in practice patterns across individual clinical sites suggests that factors other than patient clinical and sociodemographic factors may be driving selection of primary treatment.

Purpose Experimental evidence suggests that anticoagulants (ACs) may inhibit cancer growth and metastasis, but clinical data have been limited. We investigated whether use of ACs was associated with the risk of death from prostate cancer. Patients and Methods This study comprised 5,955 men in the Cancer of the Prostate Strategic Urologic Research Endeavor database with localized adenocarcinoma of the prostate treated with radical prostatectomy (RP) or radiotherapy (RT). Of them, 2,175 (37%) were receiving ACs (warfarin, clopidogrel, enoxaparin, and/or aspirin). The risk of prostate cancer–specific mortality (PCSM) was compared between the AC and non-AC groups. Results After a median follow-up of 70 months, risk of PCSM was significantly lower in the AC group compared with the non-AC group (3% v 8% at 10 years; P < .01). The risks of disease recurrence and bone metastasis were also significantly lower. In a subgroup analysis by clinical risk category, the reduction in PCSM was most prominent in patients with high-risk disease (4% v 19% at 10 years; P < .01). The benefit from AC was present across treatment modalities (RT or RP). Analysis by type of AC medication suggested that the PCSM reduction was primarily associated with aspirin. Multivariable analysis indicated that aspirin use was independently associated with a lower risk of PCSM (adjusted hazard ratio, 0.43; 95% CI, 0.21 to 0.87; P = .02). Conclusion AC therapy, particularly aspirin, was associated with a reduced risk of PCSM in men treated with RT or RP for prostate cancer. The association was most prominent in patients with high-risk disease.

5129 Background: 6 months of AST+RT was shown to improve survival vs. RT alone in men with unfavorable-risk localized PCa, but it is unknown if this benefit applied to all risk subgroups. Methods: Among 206 men with clinical T1b-T2b PCa and at least 1 unfavorable feature (PSA>10 or Gleason >=7 or MRI evidence of T3 disease) randomized to 70Gy of RT with or without 6 months of AST, we performed post-randomization subgroup analyses within four subgroups defined by both risk group (high risk [Gleason 8–10 or PSA >20] or intermediate risk [all others]), and by ACE-27 comorbidity level (no/limited comorbidity or moderate/severe comorbidity). Within the 4 subgroups a log-rank test was used to compare Kaplan Meier estimates of survival (requiring p < 0.05/4 or p < 0.0125 to adjust for multiple comparisons) and within the 2 risk groups we used Cox multivariable analysis (MVA) to assess the association of treatment with the risk of death after adjusting for known prognostic factors. Results: After a median follow-up 8.2 yrs, 74 men died. In men with no or minimal comorbidity, estimates of survival were significantly higher among those who received AST+RT vs. RT alone, regardless of whether they had intermediate risk disease (90.9 vs. 85.8% at 7yrs, p = 0.009) or high-risk disease (88.9% vs. 51.2% at 7yrs, p = 0.007). In men with moderate or severe comorbidity, no difference in survival was observed after AST+RT vs. RT in intermediate risk (p = 0.2) or high risk (p = 0.5). After adjusting for known prognostic factors, treatment with RT as compared to AST+RT was associated with an increased risk of death in men with intermediate (AHR: 3.0 [95% CI: 1.3 to 7.2]; p = 0.01) and high risk disease (AHR: 3.3 [95% CI: 0.94 to 11.3]; p = 0.06) in a model that adjusted for the interaction between treatment and comorbidity. Conclusions: Among men with T1b-T2b prostate cancer who have no or minimal comorbidity, the addition of 6 months of AST to RT was associated with improved survival in men with both intermediate risk and high-risk disease. Among men with moderate to severe comorbidity, neither risk group appeared to benefit from the addition of AST. No significant financial relationships to disclose.

181 Background: A competing risks analysis was undertaken to identify patient subgroups at greatest risk of dying from prostate cancer (CAP) after treatment with definitive external beam radiation therapy (RT) +/− androgen deprivation therapy (ADT) in the PSA era, and to determine which factors predict for survival from disease. Methods: A total of 2,675 men with localized CAP treated with RT +/− ADT at M. D. Anderson Cancer Center from 1987-2007 were evaluated. Prostate cancer-specific mortality (PCSM) and other cause mortality rates were calculated after stratifying patients according to NCCN risk group, RT dose, use of ADT, and age at treatment. In total, 21% had low-risk, 40% had intermediate-risk, and 39% had high-risk disease. Multivariate analysis (MVA) was performed using Cox regression modeling. Results: Median age was 68.5 years and median follow-up was 6.4 years. For patients with low-risk disease, only 0.2% died of CAP 10 years after treatment. None of the low-risk patients <70 years old who received ≥72 Gy died of CAP. The majority of deaths in the intermediate-risk group were also due to other causes; men ≥70 years old who received <72 Gy had the highest 10-year PCSM (5%). High-risk patients <70 years old who received <72 Gy without ADT had similar 10-year rates of CAP (15.2%) and non-CAP (18.5%) mortality. Men with high-risk disease <70 years old treated with higher doses >72 Gy were twice as likely to die from non-CAP causes (15.9%) than die from CAP (8.6%). In older men ≥70 years old with high risk disease, dose-escalation with ADT reduced 10-year PCSM from 14% to 4%, and most deaths were due to other causes (41% and 20%). On MVA, dose (p=0.002), ADT (p=0.007), PSA (p<0.0001) and Gleason score (p<0.0001) were predictive of PCSM in the high-risk group. Conclusions: Men with low- and intermediate-risk CAP treated with definitive RT are unlikely to die of disease. PCSM is higher in men with high-risk disease but can be reduced with dose escalation and ADT, although patients are still twice as likely to die of other causes. No significant financial relationships to disclose.

Purpose Data on prostate cancer (PCa) treatment in Africa remains under-reported. We present a review of the management of PCa at the cancer center of the largest tertiary referral facility in Ghana, with emphasis on curative treatment. Methods We retrospectively reviewed data on 1,074 patients seen at the National Center for Radiotherapy and Nuclear Medicine from 2003 to 2016. Patient and disease characteristics at presentation are presented using descriptive statistics. The χ2 and Fisher’s exact tests and Mann-Whitney U test were used to analyze differences between categorical and continuous variables, respectively. Methods of survival analysis were used to evaluate the relative risk of biochemical disease-free survival (bDFS). Results Seventy percent of the study population presented with localized disease. High-risk disease presentation accounted for 64.4% of these patients. Only 57.6% of patients with localized disease received curative radiotherapy. The 5-year overall survival for the curative cohort was 96% (interquartile range, 93% to 98%). The 5-year bDFS rates for low-, intermediate-, and high-risk groups were 95%, 70%, and 48%, respectively. Both Gleason score and pretreatment prostate-specific antigen were significant predictors for bDFS in multivariable analysis. Conclusion We show that the majority of patients with PCa have locally advanced disease at the time of presentation for radiotherapy. bDFS was significantly better for low- and intermediate-risk than for high-risk disease. These data emphasize the dire need to re-evaluate screening and patient education of PCa in regions of the world with high incidence and mortality as well as the need for improved access to care and treatment delivery.

222 Background: Clinical management of cancer patients according to published guidelines is an important quality indicator. Prior studies have demonstrated less aggressive treatments of elderly patients with breast and colorectal cancers, raising concern about potential undertreatment of elderly patients overall. The rate of guideline concordant management in elderly prostate cancer patients is unknown, and we examined this using the Surveillance, Epidemiologic and End Results (SEER)-Medicare linked database. Given that prostate cancer is often slow growing, we were especially interested in guideline concordance in patients with "high risk" (aggressive) prostate cancer. Methods: 15,154 Caucasian (CA) and 2,924 African American (AA) men diagnosed in 2004 to 2007 with localized prostate cancer, age 66 to 79, were included. We characterized the proportions of men who received management concordant with the National Comprehensive Cancer Network guidelines within 12 months of diagnosis. Logistic regression was used to examine the odds of receiving guideline-concordant management while accounting for race, comorbidity (NCI combined index), SEER region, and sociodemographic factors. Results: Guideline concordance was more than 80% for both CA and AA patients with low- or intermediate-risk disease. Among high-risk patients, only 63% of CA and 48% AA patients received guideline-concordant management, mostly due to no treatment or hormonal therapy alone, which offer no curative potential. Findings were almost identical in the subgroup of patients with little or no comorbidity, who have more than 10 year life expectancy on average. On multivariable analysis, AA race (OR .62, p<.001) and increasing age were associated with lower likelihood of guideline concordance for high-risk prostate cancer, but comorbidity was not. Conclusions: There is undertreatment of elderly but healthy patients with high-risk prostate cancer, the most aggressive form of this disease. Our results suggest a bias toward less aggressive treatment in elderly patients with less consideration for comorbidities or aggressiveness of cancer. Guideline concordance in elderly patients with aggressive prostate cancer is low.

5077 Background: Multidisciplinary clinics (MDCs) involving both oncologists and urologists are recommended for managing radical prostate cancer patients. The effectiveness of MDCs in arriving at best treatment decisions is unknown. We analysed patient characteristics and management decisions over 8 years in a MDC at Bart’s Hospital, London. Methods: Clinical data were collected in real time and analysed retrospectively, including demographics, tumour stage and grade, D’amico risk group, treatment choice and first clinician seen. We compared variables in 1000 consecutive patients presenting between 2011-2015 (cohort A) to 1000 patients presenting 2016-18 (cohort B) to investigate trends over time. Results: 2000 patients were included, age 65.2 ± 8.6 years and 65.9 ± 9.1 years (p=0.08), with presenting PSA 9.0 (6.3-14.4) and 9.2 (6.4-15.0) ng/ml (p=0.36), in cohort A and B respectively. Disease severity and initial treatment decision are shown in the table. In low risk disease, 126 (75%) patients had active surveillance in cohort A, and 158 (90%) in cohort B (p=0.0003). In high risk disease, 202 (59%) patients had radiotherapy compared to 194 (50%) in cohort B (p=0.011). In cohort B, 127 (39%) patients seeing oncology first had radiotherapy compared to 143 (25%) patients who saw urology first (p<0.0001). 76 (23%) and 154 (27%) patients had surgery, that saw oncology and urology first, respectively (p=0.11). Conclusions: In 2000 patients presenting to a prostate MDC over 8 years, active surveillance in low risk disease increased, radiotherapy in high risk disease reduced, and the proportion undergoing surgery was unchanged. The initial clinician seen influenced treatment choice; having both specialists in the same consultation may improve consistency of treatment decisions.

78 Background: A high percent positive biopsy cores (PBC), typically dichotomized at ≥50%, is prognostic of worse cancer-specific outcomes for patients with low- and intermediate-risk prostate cancer. The prognostic value of ≥50% PBC for patients with high-risk disease is poorly understood. We examined the association between ≥50% PBC and prostate cancer-specific mortality (PCSM) for patients with high-risk prostate cancer. Methods: We identified 7,569 men from the Surveillance, Epidemiology, and End Results program who were diagnosed with high-risk prostate cancer (Gleason 8-10, prostate-specific antigen > 20 ng/mL, or cT3-T4 stage without evidence of nodal or metastatic disease) in 2010 or 2011 and had 6-24 cores sampled at biopsy. Multivariable Fine and Gray competing risks regression was utilized to examine the association between ≥50% PBC and PCSM, with adjustments for sociodemographic and clinicopathologic factors. Results: Median follow-up was 3.8 years (interquartile range 3.3-4.3 years). 56.2% of patients (4,253) had ≥50% PBC. The 4-year unadjusted cumulative incidences of PCSM were 2.0% (95% confidence interval [CI] 1.5-2.6%) and 5.6% (95% CI 4.9-6.4%) for patients with < 50% and ≥50% PBC, respectively. On multivariable analysis, the presence of ≥50% PBC was associated with a significantly higher risk of PCSM (adjusted hazard ratio [AHR] 1.95, 95% CI 1.43-2.66, P< 0.001). On subgroup analysis, ≥50% PBC was associated with a significantly higher risk of PCSM only for cT1-T2 disease (AHR 2.21, 95% CI 1.59-3.07, P< 0.001) but not cT3-T4 disease (AHR 0.77, 95% CI 0.33-1.81, P= 0.547), with a significant interaction ( Pinteraction= 0.012). Conclusions: In this large, contemporary cohort of patients with high-risk prostate cancer, ≥50% PBC was independently associated with a two-fold increased risk of PCSM for patients with cT1-T2, but not cT3-T4, tumors. Percent PBC should be used to routinely risk stratify men with high-risk disease and identify patients who may benefit from intensification of therapy, such as adding docetaxel or abiraterone to radiotherapy with androgen deprivation therapy, to optimize cancer-specific outcomes.
