130 Background: We sought to determine which groups of patients, stratified by risk group and age, account for the greatest absolute number of deaths due to prostate cancer. Methods: Using the Surveillance, Epidemiology, and End Results (SEER) database, we identified 437,150 men diagnosed with prostate cancer from 2004 to 2014. Men were excluded if they had N1 or M1 disease, risk group could not be determined, or if prostate cancer was not their first malignancy. Men were categorized as having low (Gleason ≤6, prostate-specific antigen [PSA] < 10 ng/mL, and cT1-T2a), intermediate (Gleason 7, PSA 10-20 ng/mL, or cT2b-T2c), or high risk disease (Gleason 8-10, PSA > 20 ng/mL, or cT3-T4). We calculated the cumulative incidence of prostate cancer-specific mortality (PCSM). Results: Median follow-up was 4.8 years. The overall incidences of diagnosis of low, intermediate, and high risk disease were 29.7% (n = 129,925), 48.0% (n = 209,643), and 22.3% (n = 97,582), respectively. 5-year PCSM for men with low, intermediate, and high risk disease was 0.5%, 1.4%, and 9.4%, respectively, and the 10-year PCSM was 1.6%, 4.0%, and 16.8%. Within 10 years of diagnosis, 6.5% (n = 905) of patients who died of prostate cancer were low risk, 27.4% (n = 3,834) were intermediate risk, and 66.2% (n = 9,278) were high risk. In particular, patients age 70 or older accounted for 49.9% of all high risk prostate cancer diagnoses, but 65.3% of deaths due to high risk prostate cancer. Conclusions: While high risk disease accounted for only 22.3% of the diagnoses, it accounted for 66.2% of the prostate cancer deaths within 10 years of diagnosis. Therefore, high risk patients account for the vast majority of prostate cancer deaths and should remain the focus of the majority of our research efforts. In addition, older patients with high risk disease die of prostate cancer at a disproportionately high rate, which runs counter to the notion that the disease is less of a threat to survival in older men.

Purpose Older men are more likely to be diagnosed with high-risk prostate cancer and to have lower overall survival. As a result, age often plays a role in treatment choice. However, the relationships among age, disease risk, and prostate cancer–specific survival have not been well established. Patients and Methods We studied men in the Cancer of the Prostate Strategic Urologic Research Endeavor (CaPSURE) database with complete risk, treatment, and follow-up information. High-risk patients were identified by using the validated Cancer of the Prostate Risk Assessment (CAPRA) score. Competing risks regression was used to identify the independent impact of age on cancer-specific survival. We also analyzed the effect of local treatment on survival among older men with high-risk disease. Results In all, 26% of men age ≥ 75 years presented with high-risk disease (CAPRA score 6 to 10). Treatment varied markedly with age across risk strata; older men were more likely to receive androgen deprivation monotherapy. Controlling for treatment modality alone, or for treatment and risk, age did not independently predict cancer-specific survival. Furthermore, controlling for age, comorbidity, and risk, older men with high-risk tumors receiving local therapy had a 46% reduction in mortality compared with those treated conservatively. Conclusion Older patients are more likely to have high-risk prostate cancer at diagnosis and less likely to receive local therapy. Indeed, underuse of potentially curative local therapy among older men with high-risk disease may in part explain observed differences in cancer-specific survival across age strata. These findings support making decisions regarding treatment on the basis of disease risk and life expectancy rather than on chronologic age.

Abstract Prostate cancer (PCa) is the second most common cancer in men. The indolent course of the disease makes the treatment choice a challenge for physicians and patients. In this study, a minimally invasive method was used to evaluate the potential of molecular markers in identifying patients with aggressive disease. Cell-free plasma samples from 60 PCa patients collected before radical prostatectomy were used to evaluate the levels of expression of eight genes (AMACR, BCL2, NKX3-1, GOLM1, OR51E2, PCA3, SIM2 and TRPM8) by quantitative real-time PCR. Overexpression of AMACR, GOLM1, TRPM8 and NKX3-1 genes was significantly associated with aggressive disease characteristics, including extracapsular extension, tumor stage and vesicular seminal invasion. A trio of genes (GOLM1, NKX3-1 and TRPM8) was able to identify high-risk PCa cases (85% of sensitivity and 58% of specificity), yielding a better overall performance compared with the biopsy Gleason score and prostate-specific antigen, routinely used in the clinical practice. Although more studies are required, these circulating markers have the potential to be used as an additional test to improve the diagnosis and treatment decision of high-risk PCa patients.

Purpose Patients with high-risk prostate cancer after radical prostatectomy are at risk for death. Adjuvant androgen-deprivation therapy (ADT) may reduce this risk. We hypothesized that the addition of mitoxantrone and prednisone (MP) to adjuvant ADT could reduce mortality compared with adjuvant ADT alone. Methods Eligible patients had cT1-3N0 prostate cancer with one or more high-risk factors after radical prostatectomy (Gleason score [GS] ≥ 8; pT3b, pT4, or pN+ disease; GS 7 and positive margins; or preoperative prostate-specific antigen [PSA] > 15 ng/mL, biopsy GS score > 7, or PSA > 10 ng/mL plus biopsy GS > 6. Patients with PSA ≤ 0.2 ng/mL after radical prostatectomy were stratified by pT/N stage, GS, and adjuvant radiation plan and randomly assigned to ADT (bicalutamide and goserelin for 2 years) or ADT plus six cycles of MP. The primary end point was overall survival (OS). Median OS was projected to be 10 years in the ADT arm, requiring 680 patients per arm to detect a hazard ratio of 1.30 with 92% power and one-sided α = .05. Results Nine hundred sixty-one eligible intent-to-treat patients were randomly assigned to ADT or ADT + MP from October 1999 to January 2007, when the Data Safety Monitoring Committee recommended stopping accrual as a result of higher leukemia incidence with ADT + MP. Median follow-up was 11.2 years. The 10-year OS estimates were 87% with ADT (expected 50%) and 86% with ADT + MP (hazard ratio, 1.06; 95% CI, 0.79 to 1.43). The 10-year estimate for disease-free survival was 72% for both arms. Prostate cancer was the cause of death in 18% of patients in the ADT arm and 22% in the ADT + MP arm. More patients in the MP arm died of other cancers (36% v 18% in ADT alone arm). Conclusion MP did not improve OS and increased deaths from other malignancies. The DFS and 10-year OS in these patients treated with 2 years of ADT were encouraging compared with historical estimates, although a definitive conclusion regarding value of ADT may not be made without a nontreatment control arm.

146 Background: High-risk localized prostate cancer (PC) has suboptimal treatment outcomes due to therapeutic resistance to radiation and hormone therapy. Previous studies suggest that anticoagulant (AC) use may improve treatment outcomes in high-risk PC. We hypothesized that AC therapy confers a freedom from biochemical failure (FFBF) and overall survival (OS) benefit in patients treated with concurrent radiotherapy in patients with high-risk prostate cancer defined as Gleason Score (GS) 8 or higher, Stage T3a or higher, or prostate-specific antigen (PSA) of 20 or more. Methods: Analysis was performed of 74 patients identified who were treated with definitive external beam radiotherapy with National Comprehensive Cancer Network defined high-risk PC from 2005 to 2008 at The University of Texas Southwestern Medical Center. Of these patients, 43 took concurrent AC including aspirin (95.6%), clopidogrel (17.8%), warfarin (20%), and multiple ACs (31.1%). Associations between AC use and FFBF, OS, distant metastasis, and toxicity were explored. A minimum of 5 years of follow-up were available for all patients. Results: For patients taking any AC compared to no AC, there was improved FFBF compared to of 84.4% versus 62.1% (P = 0.0003), and for aspirin the FFBF was 83.7% versus 64% (P = 0.0008). Aspirin was also associated with reduced rates of distant metastasis of 12.2% versus 26.7% in patients who did not take aspirin (P = 0.039). On multivariate analysis, patients taking aspirin with PSA of 20 or more had 5 year OS 95.8% versus 70% (P = 0.031), and GS 9-10 had 5 year OS 88.2% versus 37.5% (P = 0.013). Conclusions: AC use was associated with a FFBF benefit in high-risk PC which translated into an OS benefit in the highest risk PC patients with PSA of 20 or more or GS 9 to 10 who are most likely to experience prostate cancer specific mortality. This hypothesis generating data suggests AC use may represent an opportunity to improve patient outcomes by overcoming therapeutic resistance.

Evidence suggests that altered adipose tissue homeostasis may be an important contributor to the development and/or progression of prostate cancer. In this study, we investigated the adipose transcriptional profiles of low- and high-risk disease to determine both prognostic potential and possible biological drivers of aggressive disease. RNA was extracted from periprostatic adipose tissue from patients categorised as having prostate cancer with either a low or high risk of progression based on tumour characteristics at prostatectomy and profiled by RNA sequencing. The expression of selected genes was then quantified by qRT-PCR in a cross-validation cohort. In the first phase, a total of 677 differentially transcribed genes were identified, from which a subset of 14 genes was shortlisted. In the second phase, a 3 gene (IGHA1,OLFM4,RERGL) signature was refined and evaluated using recursive feature selection and cross-validation, obtaining a promising discriminatory utility (area under curve 0.72) at predicting the presence of high-risk disease. Genes implicated in immune and/or inflammatory responses predominated. Periprostatic adipose tissue from patients with high-risk prostate cancer has a distinct transcriptional signature that may be useful for detecting its occult presence. Differential expression appears to be driven by a local immune/inflammatory reaction to more advanced tumours, than any specific adipose tissue-specific tumour-promoting mechanism. This signature is transferable into a clinically usable PCR-based assay, which in a cross-validation cohort shows diagnostic potential.
