Abstract
PURPOSE OF REVIEW Disparities in prostate cancer care and outcomes have been well recognized for decades. The purpose of this review is to methodically highlight known racial disparities in the care of prostate cancer patients, and in doing so, recognize potential strategies for overcoming these disparities moving forward. RECENT FINDINGS Over the past few years, there has been a growing recognition and push towards addressing disparities in cancer care. This has led to improvements in care delivery trends and a narrowing of racial outcome disparities, but as we highlight in the following review, there is more to be addressed before we can fully close the gap in prostate cancer care delivery. While disparities in prostate cancer care are well recognized in the literature, they are not insurmountable, and progress has been made in identifying areas for improvement and potential strategies for closing the care gap.

The Impact of Within-Consultation and Preconsultation Decision Aids for Localized Prostate Cancer on Patient Knowledge: Results of a Patient-Level Randomized Trial. Urology 2023; 175:90-95.

Abstract
OBJECTIVE To evaluate the role of timing (either before or during initial consultation) on the effectiveness of decision aids (DAs) to support shared-decision-making in a minority-enriched sample of patients with localized prostate cancer using a patient-level randomized controlled trial design. METHODS We conducted a 3-arm, patient-level-randomized trial in urology and radiation oncology practices in Ohio, South Dakota, and Alaska, testing the effect of preconsultation and within-consultation DAs on patient knowledge elements deemed essential to make treatment decisions about localized prostate cancer, all measured immediately following the initial urology consultation using a 12-item Prostate Cancer Treatment Questionnaire (score range 0 [no questions correct] to 1 [all questions correct]), compared to usual care (no DAs). RESULTS Between 2017 and 2018, 103 patients-including 16 Black/African American and 17 American Indian or Alaska Native men-were enrolled and randomly assigned to receive usual care (n = 33) or usual care and a DA before (n = 37) or during (n = 33) the consultation. After adjusting for baseline characteristics, there were no statistically significant proportional score differences in patient knowledge between the preconsultation DA arm (0.06 knowledge change, 95% CI -0.02 to 0.12, P = .1) or the within-consultation DA arm (0.04 knowledge change, 95% CI -0.03 to 0.11, P = .3) and usual care. CONCLUSION In this trial oversampling minority men with localized prostate cancer, DAs presented at different times relative to the specialist consultation showed no improvement in patient knowledge above usual care.

Racial Differences in Androgen Receptor (AR) and AR Splice Variants (AR-SVs) Expression in Treatment-Naïve Androgen-Dependent Prostate Cancer. Biomedicines 2023; 11:biomedicines11030648. [PMID: 36979627 PMCID: PMC10044992 DOI: 10.3390/biomedicines11030648] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/12/2022] [Revised: 02/07/2023] [Accepted: 02/13/2023] [Indexed: 02/24/2023] Open
Abstract
Androgen receptor splice variants (AR-SVs) contribute to the aggressive growth of castration-resistant prostate cancer (CRPC). AR-SVs, including AR-V7, are expressed in ~30% of CRPC, but minimally in treatment-naïve primary prostate cancer (PCa). Compared to Caucasian American (CA) men, African American (AA) men are more likely to be diagnosed with aggressive/potentially lethal PCa and have shorter disease-free survival. Expression of a truncated AR in an aggressively growing patient-derived xenograft developed with a primary PCa specimen from an AA patient led us to hypothesize that the expression of AR-SVs could be an indicator of aggressive growth both in PCa progression and at the CRPC stage in AA men. Tissue microarrays (TMAs) were created from formalin-fixed paraffin-embedded (FFPE) prostatectomy tumor blocks from 118 AA and 115 CA treatment-naïve PCa patients. TMAs were stained with AR-V7-speicifc antibody and with antibodies binding to the N-terminus domain (NTD) and ligand-binding domain (LBD) of the AR. Since over 20 AR-SVs have been identified, and most AR-SVs do not as yet have a specific antibody, we considered a 2.0-fold or greater difference in the NTD vs. LBD staining as indication of potential AR-SV expression. Two AA, but no CA, patient tumors stained positively for AR-V7. AR staining with NTD and LBD antibodies was robust in most patients, with 21% of patients staining at least 2-fold more for NTD than LBD, indicating that AR-SVs other than AR-V7 are expressed in primary treatment-naïve PCa. About 24% of the patients were AR-negative, and race differences in AR expression were not statistically significant. These results indicate that AR-SVs are not restricted to CRPC, but also are expressed in primary PCa at higher rate than previously reported. Future investigation of the relative expression of NTD vs. LBD AR-SVs could guide the use of newly developed treatments targeting the NTD earlier in the treatment paradigm.

Abstract
BACKGROUND Decision aids (DAs) can improve knowledge for prostate cancer treatment. However, the relative effects of DAs delivered within the clinical encounter and in more diverse patient populations are unknown. A multicenter cluster randomized controlled trial with a 2×2 factorial design was performed to test the effectiveness of within-visit and previsit DAs for localized prostate cancer, and minority men were oversampled. METHODS The interventions were delivered in urology practices affiliated with the NCI Community Oncology Research Program Alliance Research Base. The primary outcome was prostate cancer knowledge (percent correct on a 12-item measure) assessed immediately after a urology consultation. RESULTS Four sites administered the previsit DA (39 patients), 4 sites administered the within-visit DA (44 patients), 3 sites administered both previsit and within-visit DAs (25 patients), and 4 sites provided usual care (50 patients). The median percent correct in prostate cancer knowledge, based on the postvisit knowledge assessment after the intervention delivery, was as follows: 75% for the pre+within-visit DA study arm, 67% for the previsit DA only arm, 58% for the within-visit DA only arm, and 58% for the usual-care arm. Neither the previsit DA nor the within-visit DA had a significant impact on patient knowledge of prostate cancer treatments at the prespecified 2.5% significance level (P = .132 and P = .977, respectively). CONCLUSIONS DAs for localized prostate cancer treatment provided at 2 different points in the care continuum in a trial that oversampled minority men did not confer measurable gains in prostate cancer knowledge.

A Retrospective Observational Analysis of Overall Survival with Sipuleucel-T in Medicare Beneficiaries Treated for Advanced Prostate Cancer. Adv Ther 2020; 37:4910-4929. [PMID: 33029725 PMCID: PMC7596004 DOI: 10.1007/s12325-020-01509-5] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/01/2020] [Accepted: 09/16/2020] [Indexed: 11/29/2022]
Abstract
Introduction Since sipuleucel-T approval in 2010, the treatment landscape for metastatic castration-resistant prostate cancer (mCRPC) now includes the androgen-receptor signaling pathway inhibitors (ASPIs) abiraterone acetate or enzalutamide. In 2013 and 2014, these oral agents were approved for use in men with metastatic prostate cancer who had minimal to no symptoms. We compared overall survival (OS) in men who received their first mCRPC treatment using the Medicare Fee-for-Service 100% administrative claims research dataset with patient-level linkage to the National Death Index. Methods This retrospective cohort analysis (January 2013 to December 2017) included men who were chemo-naïve at treatment start in 2014 and who had continuous Medicare Parts A, B, and D eligibility during the 3-year observation period. We compared: first-line sipuleucel-T vs. first-line ASPIs and any-line sipuleucel-T vs. any-line ASPIs (without sipuleucel-T). We used a multivariable regression model to help control for potentially confounding factors while assessing survival outcomes. Results The model included 6044 eligible men (average age 75–78 years) with similar disease severity; > 80% were white. Median OS, presented as sipuleucel-T vs. ASPI, was 35.2 vs. 20.7 months (n, 906 vs. 5092; any-line cohort) and 34.9 vs. 21.0 months (n, 647 vs. 4810; first-line cohort). Model outcomes indicated sipuleucel-T was associated with significantly prolonged OS compared with ASPIs: adjusted hazard ratio, 0.59 (95% CI 0.527–0.651) and 0.56 (0.494–0.627) for the any-line and first-line cohorts, respectively. Conclusion This analysis suggests use of sipuleucel-T at any time was associated with improved OS compared with ASPI use alone. Of note, these analyses are intended as descriptive rather than definitive as this dataset contains limited data on key clinical factors. While selection bias is a risk in secondary claims data, this research provides important insight into real-world treatment outcomes.

Long-term follow-up of a racially and ethnically diverse population of men with localized prostate cancer who did not undergo initial active treatment. Cancer Med 2020; 9:8530-8539. [PMID: 32965775 PMCID: PMC7666755 DOI: 10.1002/cam4.3471] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/04/2020] [Revised: 06/23/2020] [Accepted: 08/23/2020] [Indexed: 11/28/2022] Open
Abstract
Background There is limited research on the racial/ethnic differences in long‐term outcomes for men with untreated, localized prostate cancer. Methods Men diagnosed with localized, Gleason ≤7 prostate cancer who were not treated within 1 year of diagnosis from 1997–2007 were identified. Cumulative incidence rates of the following events were calculated; treatment initiation, metastasis, death due to prostate cancer and all‐cause mortality, accounting for competing risks. The Cox model of all‐cause mortality and Fine‐Gray sub distribution model to account for competing risks were used to test for racial/ethnic differences in outcomes adjusted for clinical factors. Results There were 3925 men in the study, 749 Hispanic, 2415 non‐Hispanic white, 559 non‐Hispanic African American, and 202 non‐Hispanic Asian/Pacific Islander (API). Median follow‐up was 9.3 years. At 19 years, overall cumulative incidence of treatment, metastasis, death due to prostate cancer, and all‐cause mortality was 25.0%, 14.7%, 11.7%, and 67.8%, respectively. In adjusted models compared to non‐Hispanic whites, African Americans had higher rates of treatment (HR = 1.39, 95% CI = 1.15–1.68); they had an increased risk of metastasis beyond 10 years after diagnosis (HR = 4.70, 95% CI = 2.30–9.61); API and Hispanic had lower rates of all‐cause mortality (HR = 0.66, 95% CI = 0.52–0.84, and HR = 0.72, 95% CI = 0.62–0.85, respectively), and API had lower rates of prostate cancer mortality in the first 10 years after diagnosis (HR = 0.29, 95% CI = 0.09–0.90) and elevated risks beyond 10 years (HR = 5.41, 95% CI = 1.39–21.11). Conclusions Significant risks of metastasis and prostate cancer mortality exist in untreated men beyond 10 years after diagnosis, but are not equally distributed among racial/ethnic groups.

Abstract
Objective Racial disparities have been well characterized and African American (AA) patients have 30% lower 5-year survival rates than European Americans (EAs) for head and neck squamous carcinoma (HNSCC). This poorer survival can be attributed to a myriad of different factors. The purpose of this study was to characterize AA-EA similarities and differences in sociodemographic, lifestyle, clinical, and psychosocial characteristics in HNSCC patients near the time of surgery. Methods Setting: Single tertiary care center. Participants: Thirty-nine newly diagnosed, untreated HNSCC patients (n = 24 EAs,n = 15 AAs) who were to undergo surgery were recruited. Study Design: Cross-sectional study Sociodemographic, lifestyle factors, and disease factors (cancer site, AJCC clinical and pathologic stage, and HPV status)were assessed. Risk factors, leisure time, quality of life and social support were also assessed using validated questionnaires. Exposures: EA and AA patients were similar in the majority of sociodemographic factors assessed. AAs had a higher trend toward pathologically later stage disease compared to EAs and significantly increased time to treatment. Results EA and AA patients were similar in the majority of sociodemographic factors assessed. AAs had a higher trend toward pathologically later stage disease compared to EAs. AAs also had significantly increased time to treatment (P = 0.05). The majority of AA patients (62%) had later stage pathologic disease. AA were less likely to complete high school or college (P = 0.01) than their EA counterparts. Additionally, AAs were more likely to report having a gap in health insurance during the past decade (37% vs. 15%). Conclusions This preliminary study demonstrates a similar profile of demographics, clinical and psychosocial characteristics preoperatively for AAs and EAs. Key differences were AAs tending to have later pathologic stage disease, educational status, delays in treatment initiation, and gaps in health insurance.

Abstract
Prostate cancer is the most frequently diagnosed solid malignancy in men. Epidemiological studies have shown African-American men to be at higher risk for developing prostate cancer and experience higher death as compared to other ethnic groups. Establishment of prostate cancer cell lines paired with normal cells derived from the same patient is a fundamental breakthrough in cell culture technology and provides a resource to improve our understanding of cancer development and pertinent molecular events. Previous studies have demonstrated that conditional reprogramming (CR) allows the establishment and propagation of patient-derived normal and tumor epithelial cell cultures from a variety of tissue types. Here, we report a new AA prostate cell model, paired normal and cancer epithelial cells from the same patient. "Tumor" cell culture AA-103A was derived from malignant prostate tissues, and "normal" cell culture AA-103B was derived from non-malignant prostate tissues from the prostatectomy specimen of an African-American male. These paired cell cultures have been propagated under CRC conditions to permit direct comparison of the molecular and genetic profiles of the normal epithelium and adenocarcinoma cells for comparison of biomarkers, enabling patient-specific pathological analysis, and molecular and cellular characterization. STR confirmed human origin albeit no karyotypic abnormalities in the two cell lines. Further quantitative PCR analyses demonstrated characteristic markers, including the high level of basal cell marker, the keratin 5 (KRT5) in normal cells and of luminal marker, the androgen receptor (AR) as well as the programmed death-ligand 1 (PD-L1) in tumor cells. Although 3-D sphere formation was observed, the AA-103A of tumor cells did not generate tumors in vivo. We report these paired primary epithelial cultures under CRC growth as a potentially useful tool for studies to understand molecular mechanisms underlying health disparities in prostate cancer.

Abstract
Recent studies suggest a diet low in dietary magnesium intake or lower blood magnesium levels is linked with increased prostate cancer risk. This study investigates the race-specific link between blood magnesium and calcium levels, or dietary magnesium intake, and the diagnosis of low-grade and high-grade prostate cancer. The study included 637 prostate cancer cases and 715 biopsy-negative controls (50% black) recruited from Nashville, TN or Durham, NC. Blood was collected at the time of recruitment, and dietary intake was assessed by food frequency questionnaire. Percent genetic African ancestry was determined as a compliment to self-reported race. Blood magnesium levels and dietary magnesium intake were significantly lower in black compared to white men. However, magnesium levels or intake were not associated with risk of total prostate cancer or aggressive prostate cancer. Indeed, a higher calcium-to-magnesium diet intake was significantly protective for high-grade prostate cancer in black (OR = 0.66 (0.45, 0.96), p = 0.03) but not white (OR = 1.00 (0.79, 1.26), p = 0.99) men. In summary, there was a statistically significant difference in magnesium intake between black and white men, but the biological impact was unclear, and we did not confirm a lower prostate cancer risk associated with magnesium levels.

Abstract
OBJECTIVE To evaluate the mortality rates for prostate cancer according to geographical areas in Peru between 2005 and 2014. MATERIALS AND METHODS Information was extracted from the Deceased Registry of the Peruvian Ministry of Health. We analysed age-standardised mortality rates (world population) per 100 000 men. Spatial autocorrelation was determined according to the Moran Index. In addition, we used Cluster Map to explore relations between regions. RESULTS Mortality rates increased from 20.9 (2005-2009) to 24.1 (2010-2014) per 100 000 men, an increase of 15.2%. According to regions, during the period 2010-2014, the coast had the highest mortality rate (28.9 per 100 000), whilst the rainforest had the lowest (7.43 per 100 000). In addition, there was an increase in mortality in the coast and a decline in the rainforest over the period 2005-2014. The provinces with the highest mortality were Piura, Lambayeque, La Libertad, Callao, Lima, Ica, and Arequipa. Moreover, these provinces (except Arequipa) showed increasing trends during the years under study. The provinces with the lowest observed prostate cancer mortality rates were Loreto, Ucayali, and Madre de Dios. This study showed positive spatial autocorrelation (Moran's I: 0.30, P = 0.01). CONCLUSION Mortality rates from prostate cancer in Peru continue to increase. These rates are higher in the coastal region compared to those in the highlands or rainforest.

Abstract
OBJECTIVE to identify socio-demographic, clinical and psychological predictors of well-being and quality of life in men who underwent radical prostatectomy, in a 360-day follow-up. METHOD longitudinal study with 120 men who underwent radical prostatectomy. Questionnaires were used for characterization and clinical evaluation of the participant, as well as the instruments Visual Analog Scale for Pain, The Ways of Coping Questionnaire, Hospital Depression and Anxiety Scale, Satisfaction with Social Support Scale, Marital Satisfaction Scale, Subjective Well-Being Scale and Expanded Prostate Cancer Index. For data analysis, the linear mixed-effects model was used. RESULTS the socio-demographic factors age and race were not predictors of the dependent variables; time of surgery, problem-focused coping, and anxiety were predictors of subjective well-being; pain, anxiety and depression were negative predictors of quality of life; emotion-focused coping was a positive predictor. Marital dissatisfaction was a predictor of both variables. CONCLUSION predictor variables found were different from the literature: desire for changes in marital relationship presented a positive association with quality of life and well-being; emotion-focused coping was a predictor of quality of life; and anxiety was a predictor of subjective well-being.

Abstract
Background Treatments for localized prostate cancer present challenging tradeoffs in the face of uncertain treatment benefits. These options are best weighed in a process of shared decision-making with the patient’s healthcare team. Minority men experience disparities in prostate cancer outcomes, possibly due in part to a lack of optimal communication during treatment selection. Decision aids facilitate shared decision-making, improve knowledge of treatment options, may increase satisfaction with treatment choice, and likely facilitate long-term quality of life. Methods/design This study will compare the effect of two evidence-based decision aids on patient knowledge and on quality of life measured one year after treatment, oversampling minority men. One decision aid will be administered prior to specialist consultation, preparing patients for a treatment discussion. The other decision aid will be administered within the consultation to facilitate transparent, preference-sensitive, and evidence-informed deliberations. The study will utilize a four-arm, block-randomized design to test whether each decision aid alone (Arms 1 and 2) or in combination (Arm 3) can improve patient knowledge and quality of life compared to usual care (Arm 4). The study, funded by the National Cancer Institute’s Community Oncology Research Program (NCORP), will be deployed within select institutions that have demonstrated capacity to recruit minority populations into urologic oncology trials. Discussion Upon completion of the trial, we will have 1) tested the effectiveness of two evidence-based decision aids in enhancing patients’ knowledge of options for prostate cancer therapy and 2) estimated whether decision aids may improve patient quality of life one year after initial treatment choice. Trial registration Clinicaltrials.gov: NCT03103321. The trial registration date (on ClinicalTrials.gov) was April 6, 2017.

Abstract
PURPOSE OF REVIEW Comparative effectiveness research plays a vital role in healthcare delivery by guiding evidence-based practices. We performed a state-of-the-art review of comparative effectiveness research in the urology literature for 2016, utilizing a systematic approach. Seven high-impact papers are reviewed in detail. RECENT FINDINGS Across the breadth of urology, there were several important studies in comparative effectiveness research, of which we will highlight two randomized controlled trials and five observational trials: radiotherapy, prostatectomy, and active monitoring have equivalent mortality outcomes in patients with localized prostate cancer; the ideal modality of patient education is yet to be determined, and written education has minimal effect on patient perception of prostate specific antigen screening; robotic prostatectomy is associated with higher perioperative complication rates on a population basis; racial disparities exist in incontinence rates after treatment for localized prostate cancer, but not in irritative, bowel, or sexual function; androgen deprivation therapy is associated with higher fracture, peripheral artery disease, and cardiac-related complications than bilateral orchiectomy; robotic and open cystectomy offer comparable cancer-specific mortality and perioperative outcomes; and bonuses for low-cost hospitals can inadvertently reward low-quality hospitals. SUMMARY There have been major advancements in comparative effectiveness research in urology in 2016.

Abstract
OBJECTIVES To measure the relationship between randomized controlled trial (RCT) efficacy and real-world effectiveness for oncology treatments as well as how this relationship varies depending on an RCT's use of surrogate versus overall survival (OS) endpoints. METHODS We abstracted treatment efficacy measures from 21 phase III RCTs reporting OS and either progression-free survival or time to progression endpoints in breast, colorectal, lung, ovarian, and pancreatic cancers. For these treatments, we estimated real-world OS as the mortality hazard ratio (RW MHR) among patients meeting RCT inclusion criteria in Surveillance and Epidemiology End Results-Medicare data. The primary outcome variable was real-world OS observed in the Surveillance and Epidemiology End Results-Medicare data. We used a Cox proportional hazard regression model to calibrate the differences between RW MHR and the hazard ratios on the basis of RCTs using either OS (RCT MHR) or progression-free survival/time to progression surrogate (RCT surrogate hazard ratio [SHR]) endpoints. RESULTS Treatment arm therapies reduced mortality in RCTs relative to controls (average RCT MHR = 0.85; range 0.56-1.10) and lowered progression (average RCT SHR = 0.73; range 0.43-1.03). Among real-world patients who used either the treatment or the control arm regimens evaluated in the relevant RCT, RW MHRs were 0.6% (95% confidence interval -3.5% to 4.8%) higher than RCT MHRs, and RW MHRs were 15.7% (95% confidence interval 11.0% to 20.5%) higher than RCT SHRs. CONCLUSIONS Real-world OS treatment benefits were similar to those observed in RCTs based on OS endpoints, but were 16% less than RCT efficacy estimates based on surrogate endpoints. These results, however, varied by tumor and line of therapy.

Abstract
BACKGROUND Researchers are increasingly interested in using observational data to evaluate cancer outcomes following treatment, including cancer recurrence and disease-free survival. Because population-based cancer registries do not collect recurrence data, recurrence is often imputed from health claims, primarily by identifying later cancer treatments after initial treatment. The validity of this approach has not been established. RESEARCH DESIGN We used the linked Surveillance, Epidemiology, and End Results-Medicare data to assess the sensitivity of Medicare claims for cancer recurrence in patients very likely to have had a recurrence. We selected newly diagnosed stage II/III colorectal (n=6910) and female breast cancer (n=3826) patients during 1994-2003 who received initial cancer surgery, had a treatment break, and then died from cancer in 1994-2008. We reviewed all claims from the treatment break until death for indicators of recurrence. We focused on additional cancer treatment (surgery, chemotherapy, radiation therapy) as the primary indicator, and used multivariate logistic regression analysis to evaluate patient factors associated with additional treatment. We also assessed metastasis diagnoses and end-of-life care as recurrence indicators. RESULTS Additional treatment was the first indicator of recurrence for 38.8% of colorectal patients and 35.2% of breast cancer patients. Patients aged 70 and older were less likely to have additional treatment (P < 0.05), in adjusted analyses. Over 20% of patients either had no recurrence indicator before death or had end-of-life care as their first indicator. CONCLUSIONS Identifying recurrence through additional cancer treatment in Medicare claims will miss a large percentage of patients with recurrences; particularly those who are older.

Abstract
Purpose To compare 5-year biochemical control, toxicity, and patient-reported quality of life (QOL) outcomes for African American and White patients treated with proton therapy (PT) for prostate cancer. Materials and Methods We reviewed the medical records of 1,066 men with clinically localized prostate cancer. Patients were treated with definitive PT between 2006 and 2010. Patients received a median radiation dose of 78 Gy (RBE) with conventional fractionation (1.8- 2 Gy [RBE] per fraction). Sixty-eight (6.4%) men self-identified as African American and 998 (93.6%) self-identified as White. Five-year rates of biochemical control, grade 3 genitourinary and gastrointestinal toxicity, and patient-reported QOL are reported and compared between African American and White patients. Results Median biochemical follow-up was 5.0 years for both African American and White patients. Median follow-up for toxicity was 5.0 and 5.2 years, respectively. On multivariate analysis, race was not a significant predictor for 5-year freedom from biochemical failure (HR 0.8, p=0.55). No significant association was found between race and grade 3 genitourinary toxicity on multivariate analysis at 5 years (HR 2.5, p=0.10). Patient-reported QOL using median EPIC bowel, urinary incontinence, and irritative summaries scores were not significantly different between the groups. African Americans had higher median sexual summary scores at 2 years than White patients (75 vs. 54, p=0.01) but by 5+ years, the sexual summary scores were no longer significantly different (63 vs. 53, p=0.35). Conclusion With a median follow-up of 5 years, there were no racial disparities in biochemical control, grade 3 toxicity, or patient-reported QOL after PT for prostate cancer.

Abstract
BACKGROUND Relatively little is known about the relationship between race/ethnicity and patient-reported outcomes after contemporary treatments for localized prostate cancer. OBJECTIVE To test the hypothesis that treatment-related changes in urinary, bowel, sexual, and hormonal function vary by race/ethnicity. DESIGN, SETTING, AND PARTICIPANTS The Comparative Effectiveness Analysis of Surgery and Radiation (CEASAR) study is a prospective, population-based, observational study that enrolled 3708 men diagnosed with localized prostate cancer in 2011-2012. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS Patient-reported disease-specific function was measured using the 26-item Expanded Prostate Index Composite (EPIC) at baseline and 6 and 12 mo after enrollment. Mean treatment differences in function were compared by race using risk-adjusted generalized estimating equations. RESULTS AND LIMITATIONS While all race/ethnic groups reported considerable declines in scores for urinary incontinence after radical prostatectomy (RP) when compared to active surveillance, African-American men reported a greater difference than white men did (adjusted difference-in-differences 8.4 points, 95% confidence interval 2.0-14.8; p=0.01). No difference in bother scores was noted and the overall proportion of explained variation attributable to race/ethnicity was relatively small in comparison to primary treatment and baseline function. No clinically significant racial variation was noted for the sexual, bowel, irritative voiding, or hormone domains. Limitations include the lack of well-established thresholds for clinical significance using the EPIC instrument. CONCLUSION While these data demonstrate that incontinence at 1 yr after RP may be worse for African-American compared to white men, the difference appears to be modest overall. Treatment selection and baseline function explain a much greater proportion of the variation in function after treatment. PATIENT SUMMARY We observed that the effect of treatment for prostate cancer on patient-reported function did not vary dramatically by race/ethnicity. Compared to white men, African-American men experienced a somewhat more pronounced decline in urinary continence after radical prostatectomy, but the corresponding changes in bother scores were not significantly different between the two groups.

Abstract
Intensity-modulated radiation therapy (IMRT), an innovative treatment option for prostate cancer, has rapidly diffused over the past decade. To inform our understanding of racial disparities in prostate cancer treatment and outcomes, this study compared diffusion of IMRT in African American (AA) and Caucasian American (CA) prostate cancer patients during the early years of IMRT diffusion using the Surveillance, Epidemiology and End Results (SEER)-Medicare linked database. A retrospective cohort of 947 AA and 10,028 CA patients diagnosed with localized prostate cancer from 2002 through 2006, who were treated with either IMRT or non-IMRT as primary treatment within 1 year of diagnoses was constructed. Logistic regression was used to examine potential differences in diffusion of IMRT in AA and CA patients, while adjusting for socioeconomic and clinical covariates. A significantly smaller proportion of AA compared with CA patients received IMRT for localized prostate cancer (45% vs. 53%, p < .0001). Racial differences were apparent in multivariable analysis though did not achieve statistical significance, as time and factors associated with race (socioeconomic, geographic, and tumor related factors) explained the preponderance of variance in use of IMRT. Further research examining improved access to innovative cancer treatment and technologies is essential to reducing racial disparities in cancer care.

Abstract
OBJECTIVES To examine the association of changing urologists on surgical complications in men with prostate cancer. DATA SOURCES/STUDY SETTING Registry and administrative claims data from the Surveillance, Epidemiology, and End Results-Medicare database from 1995 to 2005. STUDY DESIGN A cross-sectional observational study of men with prostate cancer who underwent radical prostatectomy. METHODS Subjects were classified as having "changed urologists" if they had a different urologist who diagnosed their cancer from the one who performed their surgery. "Doubly robust" propensity score weighted multivariable logistic regression models were used to investigate the effect of changing urologists on 30-day surgical complications, late urinary complications, and long-term incontinence. PRINCIPAL FINDINGS Men who changed urologists between diagnosis and treatment had significantly lower odds of 30-day surgical complications compared with men who did not change urologists (odds ratio: 0.82; 95 percent confidence interval: 0.76-0.89), after adjustment. Changing urologists was associated with lower risks of 30-day complications for both black and white men compared with staying with the same urologist for their diagnosis and surgical treatment. CONCLUSIONS Urologist changing is associated with the observed variation in complications following radical prostatectomy. This may suggest that patients are responding to aspects of surgical quality not captured in surgical volume.

Abstract
BACKGROUND Reports suggest worse health-related outcomes among black (vs white) men diagnosed with prostate cancer, but appropriate cause-effect inferences are complicated by the relationship of race and other prognostic factors. METHODS We searched the literature to find contemporary articles focusing on mortality among black and white men with prostate cancer in equal-access healthcare systems. We also directly assessed the association of race and prostate cancer mortality by conducting an observational cohort analysis of 1270 veterans diagnosed with prostate cancer and followed for 11 to 16 years at 9 medical centers within the Veterans Health Administration. RESULTS Among 5 reports providing quantitative results for the association of race and mortality among men with prostate cancer in equal-access systems, outcomes were similar for black and white men. Race also was not a prognostic factor in the observational cohort analysis of US veterans, with an adjusted hazard ratio for black (vs white) men and prostate cancer mortality of 0.90 (95% confidence interval, 0.58-1.40; P = .65). CONCLUSIONS Mortality among black and white patients with prostate cancer is similar in equal-access healthcare systems. Studies that find racial differences in mortality (including cause-specific mortality) among men with prostate cancer may not account fully for socioeconomic and clinical factors.

Abstract
BACKGROUND Prostate-specific antigen (PSA) testing is recommended every 6 to 12 months for the first 5 years following radical prostatectomy as a means to detect potential disease recurrence. Despite substantial research on factors affecting treatment decisions, recurrence, and mortality, little is known about whether men receive guideline-concordant surveillance testing or whether receipt varies by year of diagnosis, time since treatment, or other individual characteristics. METHODS Surveillance testing following radical prostatectomy among elderly men was examined using Surveillance, Epidemiology, and End Results cancer registry data linked to Medicare claims. Multivariate logistic regression was used to examine the effect of demographic, tumor, and county-level characteristics on the odds of receiving surveillance testing within a given 1-year period following treatment. RESULTS Overall, receipt of surveillance testing was high, with 96% of men receiving at least one test the first year after treatment and approximately 80% receiving at least one test in the fifth year after treatment. Odds of not receiving a test declined with time since treatment. Nonmarried men, men with less-advanced disease, and non-Hispanic blacks and Hispanics had higher odds of not receiving a surveillance test. Year of diagnosis did not affect the receipt of surveillance tests. CONCLUSIONS Most men receive guideline-concordant surveillance PSA testing after prostatectomy, although evidence of a racial disparity between non-Hispanic whites and some minority groups exists. The decline in surveillance over time suggests the need for well-designed long-term surveillance plans following radical prostatectomy. Cancer 2013;119:3523-3530.. © 2013 American Cancer Society.

Abstract
PURPOSE We described population level trends in radical prostatectomy for patients with prostate cancer by hospitals with robotic surgery, and assessed whether socioeconomic disparities exist in access to such hospitals. MATERIALS AND METHODS After merging the NIS (Nationwide Inpatient Sample) and the AHA (American Hospital Association) survey from 2006 to 2008, we identified 29,837 patients with prostate cancer who underwent radical prostatectomy. The primary outcome was treatment with radical prostatectomy at hospitals that have adopted robotic surgery. Multivariate logistic regression was used to identify patient and hospital characteristics associated with radical prostatectomy performed at hospitals with robotic surgery. RESULTS Overall 20,424 (68.5%) patients were surgically treated with radical prostatectomy at hospitals with robotic surgery, while 9,413 (31.5%) underwent radical prostatectomy at hospitals without robotic surgery. There was a marked increase in radical prostatectomy at hospital adopters from 55.8% in 2006 and 70.7% in 2007 to 76.1% in 2008 (p <0.001 for trend). After adjusting for patient and hospital features, lower odds of undergoing radical prostatectomy at hospitals with robotic surgery were seen in black patients (OR 0.81, p <0.001) and Hispanic patients (OR 0.77, p <0.001) vs white patients. Compared to having private health insurance, being primarily insured with Medicaid (OR 0.70, p <0.001) was also associated with lower odds of being treated at hospitals with robotic surgery. CONCLUSIONS Although there was a rapid shift of patients who underwent radical prostatectomy to hospitals with robotic surgery from 2006 to 2008, black and Hispanic patients or those primarily insured by Medicaid were less likely to undergo radical prostatectomy at such hospitals.

Abstract
PURPOSE Difference in the quality of care may contribute to the less optimal prostate cancer treatment outcomes among black men compared with white men. We determined whether a racial quality of care gap exists in surgical care for prostate cancer, as evidenced by racial variation in the use of high volume surgeons and facilities, and in the quality of certain outcome measures of care. MATERIALS AND METHODS We performed cross-sectional and cohort analyses of administrative data from the Healthcare Cost and Utilization Project all-payer State Inpatient Databases, encompassing all nonfederal hospitals in Florida, Maryland and New York State from 1996 to 2007. Included in analysis were men 18 years old or older with a diagnosis of prostate cancer who underwent radical prostatectomy. We compared the use of surgeons and/or hospitals in the top quartile of annual volume for this procedure, inpatient blood transfusion, complications, mortality and length of stay between black and white patients. RESULTS Of 105,972 patients 81,112 (76.5%) were white, 14,006 (13.2%) were black, 6,999 (6.6%) were Hispanic and 3,855 (3.6%) were all other. In mixed effects multivariate models, black men had markedly lower use of high volume hospitals (OR 0.73, 95% CI 0.70-0.76) and surgeons (OR 0.67, 95% CI 0.64-0.70) compared to white men. Black men also had higher odds of blood transfusion (OR 1.08, 95% CI 1.01-1.14), longer length of stay (OR 1.07, 95% CI 1.06-1.07) and inpatient mortality (OR 1.73, 95% CI 1.02-2.92). CONCLUSIONS Using an all-payer data set, we identified concerning potential quality of care gaps between black and white men undergoing radical prostatectomy for prostate cancer.

Abstract
INTRODUCTION Previous studies by our group and others have demonstrated the importance of sociodemographic factors in cancer-related outcomes. The identification of these factors has led to novel approaches to the care of the high-risk cancer patient, specifically in the adoption of clinical interventions that convey similar benefits as favorable sociodemographic characteristics. This study examined the importance of marital status and race as prognostic indicators in men with prostate cancer. METHODS This report is a meta-analysis of 3,570 patients with prostate cancer treated in three prospective RTOG clinical trials. The Kaplan-Meier method was used to estimate the survival rate and the cumulative incidence method was used to analyze biochemical failure rate. Hazard ratios were calculated for all covariates using either the Cox or Fine and Gray's proportional hazards model or logistic regression model with associated 95% confidence intervals and p values. RESULTS Hazard ratio (HR) for overall survival (OS) for single status compared to married status was 1.36 (95% CI, 1.2 to 1.53). OS HR for non-White compared to White patients was 1.05 (CI 0.92 to 1.21). In contrast, the disease-free survival (DFS) HR and biochemical failure (BF) HR were both not significantly different neither between single and married patients nor between White patients and non-White patients. Median time to death for married men was 5.68 years and for single men was 4.73 years. Median time for DFS for married men was 7.25 years and for single men was 6.56 years. Median time for BF for married men was 7.81 years and for single men was 7.05 years. CONCLUSIONS Race was not associated with statistically significant differences in this analysis. Congruent with our previous work in other cancer sites, marital status predicted improved prostate cancer outcomes including overall survival. IMPLICATIONS FOR CANCER SURVIVORS Prostate cancer is the most common visceral cancer in men in the USA. The stratification of prostate cancer risk is currently modeled solely on pathologic prognostic factors including PSA and Gleason Score. Independent of these pathologic prognostic factors, our paper describes the central sociodemographic factor of being single as a negative prognostic indicator. Single men are at high risk of poorer outcomes after prostate cancer treatment. Intriguingly, in our group of patients, race was not a significant prognostic factor. The findings in this paper add to the body of work that describes important sociodemographic prognostic factors that are currently underappreciated in patients with cancer. Future steps will include the validation of these findings in prospective studies, and the incorporation of clinical strategies that identify and compensate for sociodemographic factors that predict for poorer cancer outcomes.

Abstract
PURPOSE The aim of this study was to evaluate the recent changes in the clinicopathologic features of prostate cancer in Korea and to compare these features with those of Western populations. MATERIALS AND METHODS We retrospectively reviewed the data of 1582 men undergoing radical prostatectomy for clinically localized prostate cancer between 1995 and 2007 at 10 institutions in Korea for comparison with Western studies. The patients were divided into two groups in order to evaluate the recent clinicopathological changes in prostate cancer: Group 1 had surgery between 1995 and 2003 (n=280) and Group 2 had surgery between 2004 and 2007 (n=1302). The mean follow-up period was 24 months. RESULTS Group 1 had a higher prostate-specific antigen level than Group 2 (10.0 ng/mL vs. 7.5 ng/mL, respectively; p<0.001) and a lower proportion of biopsy Gleason scores ≤6 (35.0% vs. 48.1%, respectively; p<0.001). The proportion of patients with clinical T1 stage was higher in Group 2 than in Group 1. Group 1 had a lower proportion of organ-confined disease (59.6% vs. 68.6%; p<0.001) and a lower proportion of Gleason scores ≤6 (21.3% vs. 33.0%; p<0.001), compared to Group 2. However, the relatively higher proportion of pathologic Gleason scores ≤6 in Group 2 was still lower than those of Western men, even though the proportion of organ-confined disease reached to that of Western series. CONCLUSION Korean men with prostate cancer currently present better clinicopathologic parameters. However, in comparison, Korean men still show relatively worse pathologic Gleason scores than Western men.

Abstract
Prostate cancer is the most prevalent cancer in males in Western countries. The reported incidence in Asia is much lower than that in African Americans and European Caucasians. Although the lack of systematic prostate cancer screening system in Asian countries explains part of the difference, this alone cannot fully explain the lower incidence in Asian immigrants in the United States and west-European countries compared to the black and non-Hispanic white in those countries, nor the somewhat better prognosis in Asian immigrants with prostate cancer in the United States. Soy food consumption, more popular in Asian populations, is associated with a 25% to 30% reduced risk of prostate cancer. Prostate-specific antigen (PSA) is the only established and routinely implemented clinical biomarker for prostate cancer detection and disease status. Other biomarkers, such as urinary prostate cancer antigen 3 RNA, may increase accuracy of prostate cancer screening compared to PSA alone. Several susceptible loci have been identified in genetic linkage analyses in populations of countries in the West, and approximately 30 genetic polymorphisms have been reported to modestly increase the prostate cancer risk in genome-wide association studies. Most of the identified polymorphisms are reproducible regardless of ethnicity. Somatic mutations in the genomes of prostate tumors have been repeatedly reported to include deletion and gain of the 8p and 8q chromosomal regions, respectively; epigenetic gene silencing of glutathione S-transferase Pi (GSTP1); as well as mutations in androgen receptor gene. However, the molecular mechanisms underlying carcinogenesis, aggressiveness, and prognosis of prostate cancer remain largely unknown. Gene-gene and/or gene-environment interactions still need to be learned. In this review, the differences in PSA screening practice, reported incidence and prognosis of prostate cancer, and genetic factors between the populations in East and West factors are discussed.

Abstract
OBJECTIVE To review the literature on racial variation in the pattern of care (PoC) and quality of care (QoC) for prostate cancer, as there are known racial disparities in the incidence and outcomes of prostate cancer. While there are some biological explanations for these differences, they do not completely explain the variation. Differences in the appropriateness and QoC delivered to men of different racial groups may contribute to disparities in outcome. METHODS We searched the USA National Library of Medicine PubMed system for articles pertaining to quality indicators in prostate cancer and racial disparities in QoC for prostate cancer. RESULTS While standards for appropriate treatment are not clearly defined, racial variation in the PoC has been reported in several studies, suggesting that African-American men may receive less aggressive treatment. There are validated QoC indicators in prostate cancer, and researchers have begun to evaluate racial variation in adherence to these quality indicators. Further quality comparisons, particularly in structural measures, may need to be performed to fully evaluate differences in QoC. CONCLUSIONS There is mounting evidence for racial variation in the PoC and QoC for prostate cancer, which may contribute to observed differences in outcome. While some of the sources of racial variation in quality and outcome have been identified through the development of evidence-based guidelines and validated quality indicators, opportunities exist to identify, study and attempt to resolve other components of the quality gap.

Abstract
OBJECTIVES To examine whether race or age disparities affected the odds of being staged among prostate cancer (PC) patients. Accurate staging is critical for determining treatment for PC. METHODS Multivariable logistic regression models examined race and age disparities with respect to the odds of being staged among PC patients using Surveillance, Epidemiology, and End Results-Medicare data. Similar analyses were performed to estimate the adjusted odds of being staged with distant metastatic vs in situ or local/regional disease. RESULTS The proportion of patients without staging ranged between 3% and 16% by age and between 6% and 8% by race. Adjusted results demonstrated statistically significant lower odds ratios (P <.05) for 70-74, 75-79, and 80+-year-olds of 0.76, 0.52, and 0.23, respectively, relative to PC patients aged 65-69. The odds of being staged for African Americans are 0.78 times that of non-Hispanic Whites (95% confidence interval = 0.72-0.86). The adjusted probability of distant metastatic disease at initial diagnosis is higher for African Americans (odds ratio = 1.61; 95% confidence interval = 1.47-1.76) and older men with odds ratios of 1.25, 1.85, and 4.33 for ages 70-74, 75-79, and 80+, respectively, compared with 65-69-year-olds (all P <.05). CONCLUSIONS Even though the overall odds of being staged increased over time, race and age disparities persisted. When staging did occur, the probability of distant metastatic disease was high for African Americans, and there were increasing odds of metastatic disease for all men with advanced age.

Abstract
OBJECTIVES To compare overall and prostate cancer-specific survival, using the Detroit Surveillance, Epidemiology, and End Results registry data, among 8679 Detroit area black and white men with localized or regional stage prostate cancer diagnosed from 1988 to 1992 to determine whether racial disparities in long-term survival remained after adjusting for treatment type and socioeconomic status (SES). METHODS The cases were geocoded to the census block-group, and SES data were obtained from the 1990 U.S. Census. Cox proportional hazards regression analysis was used to estimate the hazard ratio of death from any cause. The median follow-up was 16.5 years. RESULTS Of the 7770 localized stage cases (22% black and 78% white) and 909 regional cases (24% black and 76% white), black men were more likely to receive nonsurgical treatment (P < .001) and to be of low SES (P < .0001). The survival analyses were stratified by stage. For both stages, black men had poorer survival than white men in the unadjusted model. The adjustment for age and tumor grade had little effect on the survival differences, but adjustment for SES and treatment removed the survival differences. CONCLUSIONS Low SES and nonsurgical treatment were associated with a greater risk of death among men with prostate cancer, explaining much of the survival disadvantage for black men with prostate cancer.

Abstract
OBJECTIVE To study the effect of healthcare access and other characteristics on physician trust among black and white prostate cancer patients. METHODS A three-timepoint follow-up telephone survey after cancer diagnosis was conducted. This study analyzed data on 474 patients and their 1,320 interviews over three time periods. RESULTS Among other subpopulations, black patients who delayed seeking care had physician trust levels that were far lower than that of both Caucasians as well as that of the black patients overall. Black patients had greater variability in their levels of physician trust compared to their white counterparts. CONCLUSIONS Both race and access are important in explaining overall lower levels and greater variability in physician trust among black prostate cancer patients. Access barriers among black patients may spill over to the clinical encounter in the form of less physician trust, potentially contributing to racial disparities in treatment received and subsequent outcomes. Policy efforts to address the racial disparities in prostate cancer should prioritize improving healthcare access among minority groups.

Abstract
BACKGROUND Racial disparities in cancer outcomes have been observed in several malignancies. However, it is unclear if survival differences persist after adjusting for clinical, demographic, and treatment variables. Our objective was to determine whether racial disparities in survival exist among patients enrolled in consecutive trials conducted by the Southwest Oncology Group (SWOG). METHODS We identified 19 457 adult cancer patients (6676 with breast, 2699 with lung, 1244 with colon, 1429 with ovarian, and 1843 with prostate cancers; 1291 with lymphoma; 2067 with leukemia; and 2208 with multiple myeloma) who were treated on 35 SWOG randomized phase III clinical trials from October 1, 1974, through November 29, 2001. Patients were grouped according to studies of diseases with similar histology and stage. Cox regression was used to evaluate the association between race and overall survival within each disease site grouping, controlling for available prognostic factors plus education and income, which are surrogates for socioeconomic status. Median and ten-year overall survival estimates were derived by the Kaplan-Meier method. All statistical tests were two-sided. RESULTS Of 19 457 patients registered, 2308 (11.9%, range = 3.9%-21.6%) were African American. After adjustment for prognostic factors, African American race was associated with increased mortality in patients with early-stage premenopausal breast cancer (hazard ratio [HR] for death = 1.41, 95% confidence interval [CI] = 1.10 to 1.82; P = .007), early-stage postmenopausal breast cancer (HR for death = 1.49, 95% CI = 1.28 to 1.73; P < .001), advanced-stage ovarian cancer (HR for death = 1.61, 95% CI = 1.18 to 2.18; P = .002), and advanced-stage prostate cancer (HR for death = 1.21, 95% CI = 1.08 to 1.37; P = .001). No statistically significant association between race and survival for lung cancer, colon cancer, lymphoma, leukemia, or myeloma was observed. Additional adjustments for socioeconomic status did not substantially change these observations. Ten-year (and median) overall survival rates for African American vs all other patients were 68% (not reached) vs 77% (not reached), respectively, for early-stage, premenopausal breast cancer; 52% (10.2 years) vs 62% (13.5 years) for early-stage, postmenopausal breast cancer; 13% (1.3 years) vs 17% (2.3 years) for advanced ovarian cancer; and 6% (2.2 years) vs 9% (2.7 years) for advanced prostate cancer. CONCLUSIONS African American patients with sex-specific cancers had worse survival than white patients, despite enrollment on phase III SWOG trials with uniform stage, treatment, and follow-up.

Abstract
OBJECTIVE This study investigates associations between hospital and surgeon volume, and racial differences in recurrence after surgery for prostate cancer. METHODS Data from the 1991 to 2002 Surveillance, Epidemiology, and End-Results-Medicare database were examined for 962 black and 7387 white men who received surgery for prostate cancer within 6 months of diagnosis during 1993-1999. Cox regression models were used to estimate the relationships between volume (grouped in tertiles), recurrence or death, and race, controlling for age, Gleason grade, and comorbidity score. RESULTS Prostate cancer recurrence-free survival rates improved with hospital and surgical volume. Black men were more likely to experience recurrence than white men [hazard ratio (HR) = 1.34; 95% confidence interval (CI): 1.20-1.50]. Stratification by hospital volume revealed that racial differences persisted for medium and high volume hospitals, even after covariate adjustments (medium HR = 1.30, 95% CI: 1.04-1.61; high HR = 1.36, 95% CI: 1.07-1.73). Racial differences persisted within medium and high levels of surgeon volume as well (medium HR = 1.43, 95% CI: 1.10-1.85; high HR = 1.57, 95% CI: 1.14-2.16). CONCLUSIONS High hospital and physician volumes were not associated with reduced racial differences in recurrence-free survival after prostate cancer surgery, contrary to expectation. This study suggests that social and behavioral characteristics, and some aspects of access, may play a larger role than organizational or systemic characteristics with regard to recurrence-free survival for this population.

Abstract
The case-fatality rate following a diagnosis of prostate cancer is higher for Black men compared to White men. How this elevated rate arises is uncertain, with differences in disease biology, presentation, treatment and comorbidity having been suggested. A systematic search was conducted for articles that reported ethnic differences in overall-survival, prostate cancer specific survival (PSS) or biochemical recurrence. 48 articles met the inclusion criteria. Black men had worse overall survival (risk ratio 1.35, 95% CI 1.23-1.48) but this was not due to comorbidity alone as PSS and risk of biochemical recurrence were also elevated (1.29, 95% CI 1.13-1.47 and 1.34, 95% CI 1.23-1.46, respectively). Studies adjusting for clinical predictors and socioeconomic variables no longer supported a difference in overall survival (1.01, 95% CI 0.88-1.16), but continued to find an increased risk amongst Black men for PSS (1.13, 95% CI 1.00-1.27) and biochemical recurrence (1.25, 95% CI 1.11-1.41). Similar results were seen for studies from the pre-PSA era and free-health care settings. In contrast to others, studies of metastatic cancer did not find evidence of Black-White differences (p for interaction = 0.01). In conclusion, Black men had a poorer prognosis which was not fully explained by comorbidity, PSA screening, or access to free health care, although few studies measure these factors well. Either management differences for local disease and/or biological differences may be behind Black-White differences in prostate cancer prognosis.

Abstract
OBJECTIVE To examine disease-specific survival from prostate cancer by ethnic group in New Zealand. METHODS Analyses were based on the 7,733 men with histologically confirmed prostate cancer diagnosed from the start of 1996 to the end of 1999 in New Zealand. Five-year adjusted prostate-specific mortality rates and hazard ratios were calculated for Maori, Pacific, and European men. RESULTS In univariate analyses, Maori and Pacific men had higher mortality particularly in the first year after a diagnosis of prostate cancer than did European men. The strongest prognostic factors for prostate cancer were Gleason score and age. When survival analyses by ethnic group were adjusted for age and Gleason score the disparities in survival for Maori men and Pacific men with low-grade prostate cancers remained, with European men having the best survival. CONCLUSIONS Several possible explanations have been proposed to explain the survival disparities by ethnicity in New Zealand. Differentials in Gleason grade of disease by ethnic group explain a lot of these disparities. Further data on stage of disease at diagnosis, co-morbidity, treatment, access to health services, and behavioral and environmental factors are needed to resolve these issues.

Abstract
PURPOSE The aim of this study was to compare the biochemical disease-free survival rates for radical prostatectomy versus transperineal ultrasound-guided prostate implant for patients with early prostate cancer treated at a single institution from 1992 through 2005. MATERIALS AND METHODS The charts of 741 patients with early prostate cancer (350 implant and 391 surgery) treated from 1992 through 2005 were retrospectively reviewed. Surgery patients were treated by members of the academic Urology Section at Yale University School of Medicine. Implant patients were treated by a combined team from the Urology Section and the Department of Therapeutic Radiology at Yale Medical School. For the 350 implant patients, 35% were treated with iodine-125 and 65% with palladium-103. Of the implant patients 92% were treated with an implant alone and 8% with combined external beam radiation therapy plus an implant and 25% received short-term hormone therapy to downsize the prostate before the implant. Both surgery and implant patients were analyzed based on a group with favorable cancers (clinical stage T1c or T2, prostate-specific antigen <10, and Gleason score <7), an intermediate group (any 1 factor increased compared with the favorable group), and a poor group (any 2 factors increased compared with the favorable group). The follow-up time varied from 12 to 120 months with a mean/median follow-up time of 44 months/42 months for implant patients and 42 months/40 months for surgery patients. Prostate-specific antigen recurrence for surgery was defined as any detectable prostate-specific antigen after surgery. Prostate-specific antigen recurrence for implant was defined as the prostate-specific antigen nadir plus 2 ng/mL after implant. The biochemical disease-free survival rates were calculated using the life-table method. RESULTS The 5-year biochemical disease-free survival rates for radical prostatectomy versus implant were identical for the favorable group (93% versus 92%), intermediate group (70% versus 70%), and poor group (50% versus 52%) patients. CONCLUSIONS From 1992 through 2005, implant therapy produced equivalent 5-year biochemical disease-free survival rates compared with surgery in patients with early prostate cancer treated at a single institution.

Abstract
BACKGROUND Prostate cancer (PC) mortality is much greater for African American than for Caucasian men. To identify patient factors that might account for some of this disparity, men within 6 months of diagnosis were surveyed about health attitudes and behavior. METHODS Using Rapid Identification in the North Carolina Cancer Registry, 207 African American and 348 Caucasian recently diagnosed PC patients were identified and surveyed. RESULTS African American men were younger and less often currently married, and had lesser education, job status, and income than Caucasian men (all P < .001). African American men were at no greater distance to medical care, but had less access: poorer medical insurance coverage, more use of public clinics and emergency wards, less continuity with a primary physician, and more often omitted physician visits they felt they needed. They also expressed less trust in physicians. African American men acknowledged their greater risk of PC, accepted greater responsibility for their health, and reported more personal failures that delayed diagnosis. African American men more often requested the tests that diagnosed their cancers, which resulted more often from routinely ordered screening tests for Caucasian men. African American men expressed less interest in nontraditional treatments. CONCLUSIONS Despite lesser education, African American men in North Carolina are aware of their increased risk of cancer, the importance of treatment, and their responsibility for their health. Obstacles to timely diagnosis and appropriate care, including greater physician distrust, appear more likely to arise from reduced access and continuity of medical care arising from their worse socioeconomic position.
