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.

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.

Cancer Specific Mortality

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.

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.

AbstractBackgroundOptimal prostate cancer (PCa) screening strategies will focus on men most likely to have potentially-lethal, localized disease. Age-specific incidence rates (ASIRs) for clinical risk groups could guide risk-stratified screening.ObjectiveDetermine ASIRs and proportions of PCa diagnoses in Norway for modern risk-group and Gleason score categories.Design, Setting, and ParticipantsAll men diagnosed with PCa in Norway in 2014-2017 (n=20,356).Outcome Measurements and Statistical AnalysisPatients were assigned to clinical risk groups: low, favorable-intermediate, unfavorable-intermediate, high, regional, and metastatic, using Gleason score and clinical stage. Associations were assessed between age and (1) Gleason score (including Gleason 3+4 and 4+3) and (2) PCa risk group. Risk-group ASIRs were calculated by multiplying the overall Norwegian ASIR by the proportions observed for each category.ResultsOlder age was significantly associated with higher Gleason score and more advanced disease. For example, among men aged 55-59, 65-69, 75-79, and 85-89 years, the percentage with Gleason 8-10 disease was 16.5%, 23.4%, 37.2%, and 59.9%, respectively (p<0.001); the percentage with at least high-risk disease was 29.3%, 39.1%, 60.4%, and 90.6%, respectively. Corresponding percentages for low-risk PCa were 24.0%, 17.9%, 10.2%, and 4.1% (p<0.001). The respective maximum ASIRs (per 100,000 men) for low-risk, favorable-intermediate-risk, unfavorable-intermediate-risk, high-risk, regional, and metastatic disease were: 157.1, 183.8, 194.8, 408.3, 172.3, and 330.0; incidence for low-risk and favorable-intermediate-risk PCa peaked before age 70, while more advanced categories peaked after 70. At age 75-79 years, the ASIR of high-risk disease was approximately 6 times greater than at 55-59 years.ConclusionsRisk of clinically-significant, localized PCa increases with age. Healthy older men may be among those most likely to benefit from PCa screening.

PURPOSE We identified (1) differences in localized prostate cancer (PCa) risk group at presentation and (2) disparities in access to initial treatment for Asian American, Native Hawaiian, and Pacific Islander (AANHPI) men with PCa after controlling for sociodemographic factors. METHODS We assessed all patients in the National Cancer Database with localized PCa with low-, intermediate-, and high-risk disease who identified as Thai, White, Asian Indian, Chinese, Vietnamese, Korean, Japanese, Filipino, Hawaiian, Pacific Islander, Laotian, Pakistani, Kampuchean, and Hmong. Multivariable logistic regression defined adjusted odds ratios (AORs) with 95% CI of (1) presenting at progressively higher risk group and (2) receiving treatment or active surveillance with intermediate- or high-risk disease, adjusting for sociodemographic and clinical factors. RESULTS Among 980,889 men (median age 66 years), all AANHPI subgroups with the exception of Thai (AOR = 0.84 [95% CI, 0.58 to 1.21], P > .05), Asian Indian (AOR = 1.12 [95% CI, 1.00 to 1.25], P > .05), and Pakistani (AOR = 1.34 [95% CI, 0.98 to 1.83], P > .05) men had greater odds of presenting at a progressively higher PCa risk group compared with White patients (Chinese AOR = 1.18 [95% CI, 1.11 to 1.25], P < .001; Japanese AOR = 1.36 [95% CI, 1.26 to 1.47], P < .001; Filipino AOR = 1.37 [95% CI, 1.29 to 1.46], P < .001; Korean AOR = 1.32 [95% CI, 1.18 to 1.48], P < .001; Vietnamese AOR = 1.20 [95% CI, 1.07 to 1.35], P = .002; Laotian AOR = 1.60 [95% CI, 1.08 to 2.36], P = .018; Hmong AOR = 4.07 [95% CI, 1.54 to 10.81], P = .005; Kampuchean AOR = 1.55 [95% CI, 1.03 to 2.34], P = .036; Asian Indian or Pakistani AOR = 1.15 [95% CI, 1.07 to 1.24], P < .001; Native Hawaiians AOR = 1.58 [95% CI, 1.38 to 1.80], P < .001; and Pacific Islanders AOR = 1.58 [95% CI, 1.37 to 1.82], P < .001). Additionally, Japanese Americans (AOR = 1.46 [95% CI, 1.09 to 1.97], P = .013) were more likely to receive treatment compared with White patients. CONCLUSION Our findings suggest that there are differences in PCa risk group at presentation by race or ethnicity among Asian American, Native Hawaiian, and Pacific Islander subgroups and that there exist disparities in treatment patterns. Although AANHPI are often studied as a homogenous group, heterogeneity upon subgroup disaggregation underscores the importance of further study to assess and address barriers to PCa care.

Abstract Abstract 4860 Backgroud: Chronic lymphocytic leukemia (CLL) is one of the most frequent chronic lymphoproliferative disorders in Europe. It is characterized by persistent monoclonal lymphocitosis with localized or generalized lymphadenopathy. Despite the initial clinical presentation, it has a heterogeneous natural history, with the majority of patients living 10–12 years, but with some patients dying rapidly, within 2–3 years of diagnosis. Beside clinical prognostic factors, novel cytogenetic markers are recognized to be useful in predicting disease free and overall survival in CLL. AIMS: In a retrospective study throughout 10 years (1999-2009), we analyzed the clinical and biological presentation and compared the evolution and survival of patients with B-CLL using different cytogenetic markers. METHODS: We identified 112 cases (63 males and 49 females) of B-CLL with cytogenetic study by fluorescence in situ hybridization (FISH). RESULTS: Amongst 112 patients, the male to female (M/F) ratio was 1.3:1 and the median age was 70 (43-96) years. At diagnosis, the median lymphocyte count was 15.5 G/L (5.4-173). Fifty five patients (49%) had lymphadenopathies and seventeen (15%) had splenomegaly and/or hepatomegaly at presentation. By the revised Rai staging system seventy (63%) patients were included in low risk group, thirty (27%) in intermediate risk group and twelve (10%) in high risk group. The expression of ZAP-70 and CD38 by flow citometry was performed in 75 patients and revealed 13 (17%) patients CD38+ and 12 (16%) ZAP70+. The study of chromosomal aberrations with FISH showed thirty six patients (32%) with no abnormality, thirty six (32%) with isolated 13q deletion, fifteen (14%) with 12 trisomy, twelve (11%) with 11q deletion and thirteen (11%) with 17p deletion. Forty (36%) patients showed progressive disease in a median time of sixteen months (0-120), thirteen with 13qdel, seven with 17pdel and five with 12 trisomy. After treatment two patients showed progressive disease, six maintain a stable disease and thirty two obtain a remission, nine in complete remission. The Overall Survival (OS) at ten years was 70%. By the revised Rai staging system the OS at ten years was 80% for low risk, 70% for intermediate risk and all the high risk patients died during follow up. The OS at five years for the del13q-, 12 trisomy, del11q- and del17p- was 90%, 88%, 58% and 60%, respectively. SUMMARY: Chronic lymphocytic leukemia is currently considered a chronic disorder with a favourable outcome, but with a variable evolution to progressive disease. This retrospective study allowed the characterization of patient with CLL in our department and the acknowledgement that our results are quite similar to the published data. Disclosures: No relevant conflicts of interest to declare.

68 Background: Recently, NCCN adopted the Zumsteg-Spratt subclassification to define NCCN favorable and unfavorable intermediate-risk prostate cancer (IR-PCa). NCCN unfavorable disease is recommended to receive combination androgen deprivation therapy (ADT) and radiotherapy. To determine if genomics could help identify a subset who may safely avoid ADT, we evaluated the Decipher genomic classifier (GC) in IR-PCa treated with dose-escalated image-guided radiotherapy (DE-IGRT) alone. Methods: Our cohort comprised of 121 patients with NCCN favorable (N = 49, 40%) and unfavorable (N = 74, 60%) IR-PCa, who received 78 Gy without ADT. Diagnostic needle biopsies with the highest Gleason score (GS) and %tumor involvement were macrodissected for RNA extraction. GC scores were determined from the Decipher prostate cancer classifier assay (GenomeDx Biosciences, San Diego, CA). Primary clinical endpoint was biochemical relapse ([BCR], PSA nadir + 2ng/ml) post-DE-IGRT. We compared association with BCR against known clinicopathologic prognostic indices and the NCCN risk strata. Results: With a median follow up of 7.5y, 24 (19%) patients experienced BCR. Individual clinical indices did not predict BCR-free survival rate (BFS). NCCN risk strata was however associated with a small but significant difference in BFS (5-y 93%, favorable vs 88%, unfavourable, P = 0.046). GC scores stratified 85 (70%), 19 (16%), and 17 (14%) men into low, intermediate, and high risk of recurrence; 5-y BFS were 95%, 89%, and 59%, respectively (P < 0.001). On multivariable analysis, a hazard ratio of 4.71 (95% CI 1.81-12.28, P = 0.0015) for BCR was observed for the GC high risk group compared to low/intermediate; NCCN risk strata and intraductal variant did not achieve significance. Conclusions: In IR-PCa men treated with DE-IGRT monotherapy, Decipher GC was an independent predictor of BCR. While most men in this our cohort were stratified as NCCN unfavorable IR-PCa, the majority were GC low risk with excellent outcomes from DE-IGRT alone. In contrast, a minority with GC high risk had suboptimal outcomes, and may benefit from ADT intensification.

Lipid Parameters

Background. The effect of lipoprotein(a) (Lp(a)) on prostate cancer (PCa) is unclear. The aim of this study was to investigate the association between serum Lp(a) levels and clinicopathological features in patients with PCa. Methods. A total of 376 consecutive pathologically diagnosed PCa patients were enrolled and were classified as a low-intermediate-risk group or a high-risk group. The association of Lp(a) and the other lipid parameters including total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), triglycerides (TG), TC/HDL-C, LDL-C/HDL-C, and remnant cholesterol (RC) with clinicopathological parameters was tested by univariate and multivariate logistic regression analyses. Results. The high-risk PCa patients tended to have higher Lp(a) levels (p=0.022) while there was no significant difference regarding the other lipid parameters (p>0.05) compared to low-intermediate-risk counterparts. Patients with PSA≥100 ng/ml had significantly higher Lp(a) levels than subjects with PSA<100 ng/ml (p=0.002). Univariate logistic regression analyses revealed that high Lp(a) levels were correlated with high-risk PCa (Q4 vs. Q1, HR=2.687, 95% CI: 1.113-6.491, p=0.028), while the other lipid parameters were not correlated with high-risk PCa. In the stepwise multivariate regression analysis, the association between Lp(a) levels and high-risk PCa remained significant (Q4 vs. Q1,HR=2.890, 95% CI: 1.148-7.274, p=0.024) after adjusting for confounding factors including age, body mass index, hypertension, diabetes, coronary artery disease, and lipid-lowering drugs. Conclusions. This is the first study showing the positive association between high Lp(a) and adverse clinicopathological features of PCa. PCa patients with high Lp(a) tends to be more aggressive and should receive more attention in clinical practice.

181 Background: Studies on 15-year Post-RP survival including data on PSA relapse (PSA-Rel) are rare. We established the 15-year post-RP prostate cancer specific mortality (PCSM), to explore the time to PSA-Rel and PCSM thereafter, and to identify clinically available prognostic factors. Methods: In men prostatectomized from 1987-2004 slightly modified D`Amico risk groups were identified (T1: No palpable tumor ;”T2 unilateral”/”T2 bilateral” according to tumor palpability in one or both lobes). PSA –Rel was defined as PSA ≥4 µg/l before 2000, and thereafter as PSA >0.2 µg/l. Delay of RP was defined as RP performance 3-12 months after diagnosis. Competing risk modeling was performed with a significance level of <0.05. Results: After a median observation time of 12 years (range: 0-22), of 309 men (median age:62 years [range:40-74]) 40 have died from prostate cancer ( PCa) and 68 due to other causes (15-year PCSM: 15% [95%CI: 10-19%). No difference of PCSM was found between the low (N: 12) and the intermediate group (N: 121), the “conventional” high risk group ( N: 121) displaying a 24% PCSM rate (95% CI:16-32%) with particularly poor prognosis for men who presented with two high risk factors ( N. 32 ; PCSM: 33% [95% CI:20-46%]). The median time to PSA relapse (N: 152) was 5 years (range: 0-17), the median overall survival time after PSA- Rel being 7 years (range: 0-17). PCSM continued to increase after 10 years. Delay of RP had no impact on PCSM. Conclusions: After a median observation time of 12 years approximately 1 of 7 men with localized PCa, most of them diagnosed before the PSA- era, have died of prostate cancer. The “conventional” high-risk group is prognostically heterogeneous: Men with two high risk criteria have a particularly poor prognosis. PSA-Rel 10 years after RP is no rare event followed by survival times of >10 years. Delay of RP for up to one year had no impact on PCSM.

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.
