Factors influencing prostate cancer treatment decisions for African American and white men.

BACKGROUND: Prostate cancer racial disparities in mortality outcomes are the largest in all of oncology, and less aggressive treatment received by African American (AA) patients versus white patients is likely a contributing factor. However, the reasons underlying the differences in treatment are unclear. METHODS: This study examined a prospective, population-based cohort of 1170 men with newly diagnosed nonmetastatic prostate cancer enrolled from 2011 to 2013 before treatment throughout North Carolina. By phone survey, each participant was asked to rate the aggressiveness of his cancer, and his response was compared to the actual diagnosis based on a medical record review. Participants were also asked to rate the importance of 10 factors for their treatment decision-making process. RESULTS: Among AA and white patients with low-risk cancer (according to National Comprehensive Cancer Network guidelines), 78% to 80% perceived their cancers to be "not very aggressive." However, among high-risk patients, 54% of AA patients considered their cancers to be "not very aggressive," whereas 24% of white patients did (P < .001). Although both AA and white patients indicated that a cure was a very important decision-making factor, AAs were significantly more likely to consider cost, treatment time, and recovery time as very important. In a multivariable analysis, perceived cancer aggressiveness and cure as the most important factor were significantly associated with receiving any aggressive treatment and were associated with surgery (vs radiation). After adjustments for these factors and sociodemographic factors, race was not significantly associated with the treatment received. CONCLUSIONS: Racial differences in perceived cancer aggressiveness and factors important in treatment decision making provide novel insights into reasons for the known racial disparities in prostate cancer as well as potential targets for interventions to reduce these disparities.

Black Pastors' Views on preaching about sex: barriers, facilitators, and opportunities for HIV prevention messaging.

OBJECTIVES: Despite the disproportionately high rates of heterosexually transmitted HIV infection among US Blacks and ongoing need for effective inexpensive behavioral interventions, the use of sermons as an HIV prevention tool in Black churches has received little research attention. The Black church plays an important role in Black communities and is a potential ally in development and delivery of sexual risk prevention messages. The objective of this study was to examine Black pastors' thoughts about whether sermons should address issues related to heterosexual relationships - and the barriers and facilitators to discussing these topics in a sermon setting. DESIGN: We conducted in-depth semi-structured, individual interviews among 39 pastors of Black churches in North Carolina and analyzed the interview data using thematic analysis strategies based on grounded theory. RESULTS: Pastors expressed widely ranging opinions, especially about discussion of condom use, but generally agreed that sermons should discuss marriage, abstinence, monogamy, dating, and infidelity - behaviors that impact sexual networks and HIV transmission. The major barriers to incorporation of these subjects into sermons include the extent to which a concept undermines their religious beliefs and uncertainty about how to incorporate it. However, scriptural support for a prevention message and the pastor's perception that the message is relevant to the congregation facilitate incorporation of related topics into sermons. CONCLUSIONS: These findings have implications for the potential utility of sermons as an HIV prevention tool and suggest that it is possible for public health professionals and pastors of Black churches to form partnerships to develop messages that are consonant with pastors' religious convictions as well as public health recommendations.

Phase II trial of palbociclib in patients with metastatic urothelial cancer after failure of first-line chemotherapy.

BACKGROUND: The majority of urothelial cancers (UC) harbor alterations in retinoblastoma (Rb) pathway genes that can lead to loss of Rb tumour suppressor function. Palbociclib is an oral, selective inhibitor of CDK 4/6 that restores Rb function and promotes cell cycle arrest. METHODS: In this phase II trial, patients with metastatic platinum-refractory UC molecularly selected for p16 loss and intact Rb by tumour immunohistochemistry received palbociclib 125 mg p.o. daily for 21 days of a 28-day cycle. Primary endpoint was progression-free survival at 4 months (PFS4) using a Simon's two-stage design. Next-generation sequencing including Rb pathway alterations was conducted. RESULTS: Twelve patients were enrolled and two patients (17%) achieved PFS4 with insufficient activity to advance to stage 2. No responses were seen. Median PFS was 1.9 months (95% CI 1.8-3.7 months) and median overall survival was 6.3 months (95% CI 2.2-12.6 months). Fifty-eight percent of patients had grade ≥3 hematologic toxicity. There were no CDKN2A alterations found and no correlation of Rb pathway alterations with clinical outcome. CONCLUSIONS: Palbociclib did not demonstrate meaningful activity in selected patients with platinum-refractory metastatic UC. Further development of palbociclib should only be considered with improved integral biomarker selection or in rational combination with other therapies.

Association Between Choice of Radical Prostatectomy, External Beam Radiotherapy, Brachytherapy, or Active Surveillance and Patient-Reported Quality of Life Among Men With Localized Prostate Cancer.

Importance: Patients diagnosed with localized prostate cancer have to decide among treatment strategies that may differ in their likelihood of adverse effects. Objective: To compare quality of life (QOL) after radical prostatectomy, external beam radiotherapy, and brachytherapy vs active surveillance. Design, Setting, and Participants: Population-based prospective cohort of 1141 men (57% participation among eligible men) with newly diagnosed prostate cancer were enrolled from January 2011 through June 2013 in collaboration with the North Carolina Central Cancer Registry. Median time from diagnosis to enrollment was 5 weeks, and all men were enrolled with written informed consent prior to treatment. Final follow-up date for current analysis was September 9, 2015. Exposures: Treatment with radical prostatectomy, external beam radiotherapy, brachytherapy, or active surveillance. Main Outcomes and Measures: Quality of life using the validated instrument Prostate Cancer Symptom Indices was assessed at baseline (pretreatment) and 3, 12, and 24 months after treatment. The instrument contains 4 domains-sexual dysfunction, urinary obstruction and irritation, urinary incontinence, and bowel problems-each scored from 0 (no dysfunction) to 100 (maximum dysfunction). Propensity-weighted mean domain scores were compared between each treatment group vs active surveillance at each time point. Results: Of 1141 enrolled men, 314 pursued active surveillance (27.5%), 469 radical prostatectomy (41.1%), 249 external beam radiotherapy (21.8%), and 109 brachytherapy (9.6%). After propensity weighting, median age was 66 to 67 years across groups, and 77% to 80% of participants were white. Across groups, propensity-weighted mean baseline scores were 41.8 to 46.4 for sexual dysfunction, 20.8 to 22.8 for urinary obstruction and irritation, 9.7 to 10.5 for urinary incontinence, and 5.7 to 6.1 for bowel problems. Compared with active surveillance, mean sexual dysfunction scores worsened by 3 months for patients who received radical prostatectomy (36.2 [95% CI, 30.4-42.0]), external beam radiotherapy (13.9 [95% CI, 6.7-21.2]), and brachytherapy (17.1 [95% CI, 7.8-26.6]). Compared with active surveillance at 3 months, worsened urinary incontinence was associated with radical prostatectomy (33.6 [95% CI, 27.8-39.2]); acute worsening of urinary obstruction and irritation with external beam radiotherapy (11.7 [95% CI, 8.7-14.8]) and brachytherapy (20.5 [95% CI, 15.1-25.9]); and worsened bowel symptoms with external beam radiotherapy (4.9 [95% CI, 2.4-7.4]). By 24 months, mean scores between treatment groups vs active surveillance were not significantly different in most domains. Conclusions and Relevance: In this cohort of men with localized prostate cancer, each treatment strategy was associated with distinct patterns of adverse effects over 2 years. These findings can be used to promote treatment decisions that incorporate individual preferences.

Responding to a Community's Concern: A Comparison of Breast Cancer Characteristics and Initial Treatment in Three Selected North Carolina Counties.

BACKGROUND A 2007 national report identified North Carolina's Edgecombe County as having among the highest breast cancer incidence and mortality rates nationally, motivating the initiation of a task force and other local efforts to address the problem. The goal of this study is to examine county breast cancer characteristics before and after the report, including whether geographic variation may mask racial disparities in this majority African American community.METHOD With guidance from community partners, breast cancer cases from 2000 to 2012 in Edgecombe, Nash, and Orange Counties (N = 2,641) were obtained from the North Carolina Central Cancer Registry. Bivariate and trend analyses of tumor and treatment characteristics were examined by county and race.RESULTS Women in Edgecombe and Nash Counties were diagnosed with more advanced stage, higher grade tumors. African Americans in Edgecombe and Nash Counties were diagnosed with advanced disease more often than African Americans in Orange County. Average time-to-treatment was well within guideline recommendations. Incidence and mortality rates appear to have declined, with variation in measures of racial differences over time.LIMITATIONS Changes in coding standards across the observation period required reliance on coarse measures that may partially mute useful findings.CONCLUSIONS Racial disparities remain a concern in North Carolina; however, they appear to be less profound than in the 2007 national report. The portentous statistics in the report represent an all-time high, after which some, but not all, measures reflect positive change amidst ongoing local efforts to improve breast cancer knowledge and care.

Long-term survival of participants in the prostate cancer prevention trial.

BACKGROUND: In the Prostate Cancer Prevention Trial (PCPT), finasteride significantly reduced the risk of prostate cancer but was associated with an increased risk of high-grade disease. With up to 18 years of follow-up, we analyzed rates of survival among all study participants and among those with prostate cancer. METHODS: We collected data on the incidence of prostate cancer among PCPT participants for an additional year after our first report was published in 2003 and searched the Social Security Death Index to assess survival status through October 31, 2011. RESULTS: Among 18,880 eligible men who underwent randomization, prostate cancer was diagnosed in 989 of 9423 (10.5%) in the finasteride group and 1412 of 9457 (14.9%) in the placebo group (relative risk in the finasteride group, 0.70; 95% confidence interval [CI], 0.65 to 0.76; P<0.001). Of the men who were evaluated, 333 (3.5%) in the finasteride group and 286 (3.0%) in the placebo group had high-grade cancer (Gleason score, 7 to 10) (relative risk, 1.17; 95% CI, 1.00 to 1.37; P=0.05). Of the men who died, 2538 were in the finasteride group and 2496 were in the placebo group, for 15-year survival rates of 78.0% and 78.2%, respectively. The unadjusted hazard ratio for death in the finasteride group was 1.02 (95% CI, 0.97 to 1.08; P=0.46). Ten-year survival rates were 83.0% in the finasteride group and 80.9% in the placebo group for men with low-grade prostate cancer and 73.0% and 73.6%, respectively, for those with high-grade prostate cancer. CONCLUSIONS: Finasteride reduced the risk of prostate cancer by about one third. High-grade prostate cancer was more common in the finasteride group than in the placebo group, but after 18 years of follow-up, there was no significant between-group difference in the rates of overall survival or survival after the diagnosis of prostate cancer.

Enrollment and Racial Disparities in Cancer Treatment Clinical Trials in North Carolina.

BACKGROUND: Clinical trials provide access to innovative, high-quality cancer treatment. Simultaneously, broad access helps to ensure that trials include heterogeneous patient populations, which improves the generalizability of findings and the development of interventions that are effective for diverse populations. We provide updated data describing enrollment into cancer treatment trials in North Carolina. METHODS: For the period 1996-2009, person-level data regarding cancer clinical trial enrollment and cancer incidence were obtained from the North Carolina Central Cancer Registry and the National Cancer Institute (NCI). Enrollment rates were estimated as the ratio of trial enrollment to cancer incidence for race, sex, and year for each county, Area Health Education Center region, and the state overall. Enrollment rates for common cancers are presented. RESULTS: From 1996 to 2009, North Carolina NCI treatment trial enrollment rates were 2.4% and 2.2% for white patients and minority patients, respectively. From 2007 to 2009, rates were 3.8% for white women, 3.5% for minority women, 1.3% for white men, and 1.0% for minority men; there was greater enrollment among more urban populations (2.4%) than among the most rural populations (1.5%). LIMITATIONS: This study is limited to NCI-sponsored treatment trials in North Carolina. Policies governing collection of original data necessitate a delay in data availability. CONCLUSIONS: Effort is needed to ensure trial access and enrollment among all North Carolina populations. Specifically, we identified racial and sex disparities, particularly for certain cancers (eg, breast cancer). Programs in North Carolina and across the nation can use the methods we employed to assess their success in broadening clinical trial enrollment to include diverse populations.

Perceptions of Cancer Clinical Research Among African American Men in North Carolina.

ACKNOWLEDGEMENTS: The authors are grateful to the men and women who participated in our Focus Groups and shared with us their very personal cancer experience. Their insight is valuable, and will inform and improve cancer care for future generations. The authors thank the Greensboro area Community Research Advocates - especially April Durr, Elvira Mebane, Marie McAdoo, Kathy Norcott, and Cindy Taylor - who assisted in the conduct of the study, including interpretation of results. They also thank Gratia Wright of First Research Group for her expertise in moderating and executing all of the focus groups, and Lindsey Haynes-Maslow for her assistance in responding to reviewer comments. The study was funded as a part of the Carolina Community Network program, funded by a grant from the National Cancer Institute (U01-CA114629). This study was reviewed and approved by the Institutional Review Board (IRB) at the University of North Carolina at Chapel Hill. OBJECTIVE: The problem of cancer health disparities is substantial. Clinical trials are widely advocated as a means of reducing disparities and bringing state-of-the-art care to the broader community, where most cancer care is delivered. This study sought to develop a better understanding of why disproportionately few African American men enroll in clinical trials given their substantial cancer burden. DESIGN: This study applied community-based participatory research (CBPR) methods to design and conduct four focus groups of African American male cancer survivors and their caregivers in North Carolina. RESULTS: Among major themes, participants expressed confusion about the relationship between clinical trials, treatment, and research: signifying patient confusion and misinterpretation of common clinical trial terminology. Social norms including gender barriers and generational differences remain problematic; participants often reported that men do not talk about health issues, are unwilling to go to the doctor, and exhibit misapprehension and distrust regarding trials. Participants perceived this misunderstanding as detrimental to community health and expressed the need for more clarity in clinical trials information and a more fundamental social openness and communication about cancer detection and treatment. CONCLUSION: Findings indicate the importance of clinical trial education in both traditional provider referral to trials and also in general patient navigation. To dispel pervasive misapprehension regarding placebos, clinical trial information should emphasize the role of standard care in modern cancer treatment trials. Many participants described willingness to participate in a trial upon physician recommendation, suggesting merit in improving patient-physician communication through culturally competent terminology and trial referral systems.

Examining characteristics of congregation members willing to attend health promotion in African American churches.

BACKGROUND: Although churches are an important partner for improving health within the African American community, it is not known how congregants are best reached by health promotion activities and thus how best to target members in recruitment. This study examined how characteristics of churches and congregants' beliefs and interests in faith-based health promotion related to their willingness to attend church-based health promotion activities. METHOD: We surveyed adult congregants (n = 1,204) of 11 predominately African American churches in North Carolina. Surveys collected data within four domains: demographics (age, sex, education), behavioral (church attendance, respondent food choices, and physical activity), cognitive (church-based health promotion belief, Bible-based healthy living interest, healthy living resource interest), or environmental (family health, church travel distance, church health ministry activity, church members' food choices). Analyses used a dichotomous outcome, interest in attending programs offered by the health ministry. Domain-specific models were constructed. Logistic generalized estimating equations adjusted for clustering. RESULTS: Of the 1,204 congregants, 72% were female, 57% were 50 years or older, 84% had a high school education or more, and 77% had a chronic health condition. In bivariate analyses and in models adjusting for all four domains, cognitive factors had the highest odds of willingness to attend. CONCLUSION: Congregants' belief in the church's role in health promotion and their desire to learn about healthy behaviors highlight the role of the African American church as a partner in addressing health disparities and the need to capitalize on this expectation through stronger partnerships between medical and faith communities.

Participating in research: attitudes within the African American church.

We assessed associations between pastor and congregant characteristics and congregant attitudes about research participation among African American churches. Respondents shared their attitudes regarding how willing, ready, and confident they were about research participation. The outcome measure, the index of research preparedness, summed responses across the domains of willingness, readiness, and confidence. Pastor age and pastor educational attainment were independently associated with a congregants' higher index of research preparedness. Young and educated pastors were significantly associated with congregant attitudes about participation preparedness, a finding that highlights the importance of the pastor regarding congregant research participation decisions.

Exploring factors related to clinically advanced fibrosis in patients with nonalcoholic fatty liver disease or nonalcoholic steatohepatitis.

OBJECTIVES: To describe the clinical profile of nonalcoholic fatty liver disease (NAFLD) or nonalcoholic steatohepatitis (NASH) patients in a Texas integrated delivery network (IDN) and elucidate the local relationship between patient factors and the risk of advanced fibrosis. METHODS: This observational, retrospective, cross-sectional study utilized existing data from the electronic health record at a large Texas IDN. Data was collected during the study period from 1 January 2019, to 1 March 2023. Patient characteristics, comorbidities, labs, and medication orders were collected from the most recent encounter in which a Fibrosis-4 (FIB-4) score could be calculated. Chi square tests and analysis of variance (ANOVA) tests were conducted to evaluate differences among the three fibrosis risk categories. Ordinal logistic regression was utilized to assess associations between select variables and a higher risk of advanced fibrosis. RESULTS: A total of 56,253 patients were included in the study. 34,839 (61.9%) were Low-Risk 15,578 (27.7%) were Intermediate-Risk, and 5,836 (10.4%) were High-Risk of advanced fibrosis. Results showed that up to 70.4% of patients within a risk group were obese. Only 49.5% of patients in the High-Risk group had at least one gastroenterologist or hepatologist visit. Males, Medicare patients, former smokers, and those with hypertension, type 2 diabetes, and chronic kidney disease were associated with a higher risk of advanced fibrosis. CONCLUSION: This study highlights the need for early screening and proactive management of metabolic risk factors for patients with NAFLD/NASH. The findings indicate a notable prevalence of obesity in the study population, a need for specialist referral for those at High-Risk of advanced fibrosis, and the importance of routine labs to evaluate metabolic factors. Primary care providers may be ideal providers to target these interventions and address this care need.

Implementing a Quality Intervention to Improve Confidence in Outpatient Venous Thromboembolism Management.

INTRODUCTION: Guidelines recommend that patients with acute venous thromboembolism (VTE) represented by low-risk deep vein thrombosis (DVT) and pulmonary embolism (PE) receive initial treatment at home versus at the hospital, but a large percentage of these patients are not managed at home. This study assessed the effectiveness of a quality intervention on provider knowledge and confidence in evaluating outpatient treatment for patients with VTE in the emergency department (ED). METHODS: A pilot program to overcome obstacles to outpatient VTE treatment in appropriate patients was initiated at Baylor Scott & White Health Temple ED. Subsequently, a formalized quality intervention with a targeted educational program was developed and delivered to ED providers. Provider surveys were administered pre- and post-quality intervention in order to assess clinical knowledge, confidence levels, and perceived barriers. Patient discharge information was extracted from electronic health records. RESULTS: Twenty-five ED providers completed the pre- and post-surveys; 690 and 356 patients with VTE were included in the pre- and post-pilot and pre- and post-quality intervention periods, respectively. Many ED providers reported that a major barrier to discharging patients to outpatient care was the lack of available and adequate patient follow-up appointments. Notably, after the quality intervention, an increase in provider clinical knowledge and confidence scores was observed. Discharge rates for patients with VTE increased from 25.6% to 27.5% after the pilot intervention and increased from 28.5% to 29.9% after the quality intervention, but these differences were not statistically significant. Despite instantaneous uptick in discharge rates after the interventions, there was not a long-lasting effect. CONCLUSION: Although the quality intervention led to improvements in provider clinical knowledge and confidence and identified barriers to discharging patients with VTE, discharge rates remained stable, underscoring the need for additional endeavors.

When patients develop blood clots in their veins or have blood clots travel to their lungs, they may seek treatment at the hospital emergency department. As a best practice, most people can treat blood clots with medicines at home; however, many patients are treated at the hospital. This study looked at how an education program for doctors in the hospital could help more patients be treated at home. The education program improved doctors' knowledge and confidence when evaluating patients with blood clots who could be treated at home. However, this study found that the number of patients treated at home was the same before and after the doctors participated in the education program. Two major problems that prevented patients from being treated at home were not having follow-up appointments readily available and patients taking their medicine as needed. More and different types of programs may help doctors understand the best ways to treat patients with blood clots in the emergency department.

Receipt of National Comprehensive Cancer Network guideline-concordant prostate cancer care among African American and Caucasian American men in North Carolina.

BACKGROUND: African Americans have a higher incidence of prostate cancer and experience poorer outcomes compared with Caucasian Americans. Racial differences in care are well documented; however, few studies have characterized patients based on their prostate cancer risk category, which is required to differentiate appropriate from inappropriate guideline application. METHODS: The medical records of a population-based sample of 777 North Carolina men with newly diagnosed prostate cancer were studied to assess the association among patient race, clinical factors, and National Comprehensive Cancer Network (NCCN) guideline-concordant prostate cancer care. RESULTS: African Americans presented with significantly higher Gleason scores (P = .025) and prostate-specific antigen levels (P = .008) than did Caucasian Americans. However, when clinical T stage was considered as well, difference in overall risk category only approached statistical significance (P = .055). Across risk categories, African Americans were less likely to have surgery (58.1% versus 68.0%, P = .004) and more likely to have radiation (39.0% versus 27.4%, P = .001) compared with Caucasian Americans. However, 83.5% of men received guideline-concordant care within 1 year of diagnosis, which did not differ by race in multivariable analysis (odds ratio = 0.83; 95% confidence interval = 0.54-1.25). Greater patient-perceived access to care was associated with greater odds of receiving guideline-concordant care (odds ratio = 1.06; 95% confidence interval = 1.01-1.12). CONCLUSIONS: After controlling for NCCN risk category, there were no racial differences in receipt of guideline-concordant care. Efforts to improve prostate cancer treatment outcomes should focus on improving access to the health care system.

Racial differences in time from prostate cancer diagnosis to treatment initiation: a population-based study.

BACKGROUND: Timely delivery of care has been identified by the Institute of Medicine as an indicator for quality health care, and treatment delay is a potentially modifiable obstacle that can contribute to the disparities among African American (AA) and Caucasian patients in prostate cancer recurrence and mortality. Using the Surveillance, Epidemiologic and End Results (SEER)-Medicare linked database, we compared time from diagnosis to treatment in AA and Caucasian prostate cancer patients. METHODS: A total of 2506 AA and 21,454 Caucasian patients diagnosed with localized prostate cancer from 2004 through 2007 and treated within 12 months were included. Linear regression was used to assess potential differences in time to treatment between AA and Caucasian patients, after adjusting for sociodemographic and clinical covariates. RESULTS: Time from diagnosis to definitive (prostatectomy and radiation) treatment was longer for AA patients in all risk groups, and most pronounced in high-risk cancer (96 versus 105 days, P < .001). On multivariate analysis, racial differences to any and definitive treatment persisted (ß = 7.3 and 7.6, respectively, for AA patients). Delay to definitive treatment was longer in high-risk (versus low-risk) disease and in more recent years. CONCLUSIONS: AA patients with prostate cancer experienced longer time from diagnosis to treatment than Caucasian patients with prostate cancer. AA patients appear to experience disparities across all aspects of this disease process, and together these factors in receipt of care plausibly contribute to the observed differences in rates of recurrence and mortality among AA and Caucasian patients with prostate cancer.

Who makes the decision regarding the treatment of clinically localized prostate cancer--the patient or physician?: results from a population-based study.

BACKGROUND: The current study examined how patients' sociodemographic, cancer-related, and subjective affective factors impacted their role in treatment decision-making. METHODS: The patient sample (N = 788) was taken from a prospective follow-up study of a population-based cohort. Participants included 343 African American and 445 Caucasian-American patients with clinically localized prostate cancer. Multinomial logistic regression was used to investigate relations between the explanatory variables and the nominal 3-level decision-making variable: patient-only, patient-physician shared, and physician-only. RESULTS: Approximately 41% of patients reported patient-only decision-making, 45% reported shared decision-making, and 13% reported physician-only decision-making. The odds of patient-only over physician-only decision-making were greater for younger men (vs those aged ≥ 65 years) (odds ratio [OR], 1.68; 95% confidence interval [95% CI], 1.03-2.74), and were less for men with high (vs low) cancer aggressiveness (OR,0.29; 95% CI, 0.15-0.55). The odds of shared over physician-only decision-making were less for men with high (vs low) cancer aggressiveness (OR, 0.40; 95% CI, 0.22-0.73). Greater odds of patient-only and shared decision-making also were found to be associated with greater concerns about the physical impact of treatment and having enough time for decision-making and lower scores of receiving advice from others. CONCLUSIONS: The findings of the current study indicate that, to facilitate a more patient-oriented decision-making process regarding treatment in those with clinically localized prostate cancer, clinicians need to tailor their interventions according to patient age and cancer aggressiveness, help reduce patient concerns and misconceptions regarding the physical impact of treatments, allow sufficient time for patients to consider treatment options, and assist patients in balancing advice and information received from different sources.

An interrupted time series study of electronic health record clinical decision support for providers caring for patients with atrial fibrillation at increased stroke risk.

PURPOSE: To measure the effect of clinical decision support (CDS) on anticoagulation rates in patients with atrial fibrillation (AFib) or atrial flutter (AFlut) at high stroke risk and receiving care in outpatient settings, and to assess provider response to CDS. METHODS: This observational, quasi-experimental, interrupted time series study utilized electronic health record data at a large integrated delivery network in Texas from April to November 2020. CDS consisted of an electronic Best Practice Advisory (BPA)/alert (Epic Systems Corporation, Verona, WI) with links to 2 AFib order sets displayed to providers in outpatient settings caring for non-anticoagulated patients with AFib and elevated CHA2DS2VASc scores. Weekly outpatient anticoagulation rates were assessed in patients with high stroke risk before and after implementation of CDS. Alert actions and acknowledgment reasons were evaluated descriptively. RESULTS: Mean (SD) weekly counts of eligible patients were 8,917 (566) before and 8,881 (811) after implementation. Weekly anticoagulation rates increased during the pre-BPA study period (ß1 = 0.07%; SE, 0.02%; P = 0.0062); however, there were no significant changes in the level (ß2 = 0.60%; SE, 0.42%; P = 0.1651) or trend (ß3 = -0.01%; SE, 0.05%; P = 0.8256) of anticoagulation rates associated with CDS implementation. In encounters with the BPA/alert displayed (n = 17,654), acknowledgment reasons were provided in 4,473 (25.3%) of the encounters, with prescribers most commonly citing bleeding risk (n = 1,327, 7.5%) and fall risk (n = 855, 4.8%). CONCLUSION: There was a significant trend of increasing anticoagulation rates during the pre-BPA period, with no significant change in trend during the post-BPA period relative to the pre-BPA period.

How does health literacy affect quality of life among men with newly diagnosed clinically localized prostate cancer? Findings from the North Carolina-Louisiana Prostate Cancer Project (PCaP).

BACKGROUND: Health literacy deficits affect half of the US overall patient population, especially the elderly, and are linked to poor health outcomes among noncancer patients. Yet little is known about how health literacy affects cancer populations. The authors examined the relation between health-related quality of life (HRQOL) and health literacy among men with prostate cancer. METHODS: Data analysis included 1581 men with newly diagnosed clinically localized prostate cancer from a population-based study, the North Carolina-Louisiana Prostate Cancer Project (PCaP). Participants completed assessment of health literacy using Rapid Estimate of Adult Literacy in Medicine (REALM) and HRQOL using the Short Form-12 General Health Survey (SF12). Bivariate and multivariate regression was used to determine the potential association between REALM and HRQOL, while controlling for sociodemographic and illness-related variables. RESULTS: Higher health literacy level was significantly associated with better mental well-being (SF12-Mental Component Summary [MCS]; P < .001) and physical well-being (SF12-Physical Component Summary [PCS]; P < .001) in bivariate analyses. After controlling for sociodemographic (age, marital status, race, income, and education) and illness-related factors (types of cancer treatment, tumor aggressiveness, and comorbidities), health literacy remained significantly associated with SF12-MCS scores (P < .05) but not with SF12-PCS scores. CONCLUSIONS: Among patients with newly diagnosed localized prostate cancer, those with low health literacy levels were more vulnerable to mental distress than those with higher health literacy levels, but physical well-being was no different. These findings suggest that health literacy may be important in patients managing prostate cancer and the effects of treatment, and provide the hypothesis that supportive interventions targeting patients with lower health literacy may improve their HRQOL.

Impact of distance to a urologist on early diagnosis of prostate cancer among black and white patients.

PURPOSE: We examined whether an increased distance to a urologist is associated with a delayed diagnosis of prostate cancer among black and white patients, as manifested by higher risk disease at diagnosis. MATERIALS AND METHODS: North Carolina Central Cancer Registry data were linked to Medicare claims for patients with incident prostate cancer diagnosed in 2004 to 2005. Straight-line distances were calculated from the patient home to the nearest urologist. Race stratified multivariate ordinal logistic regression was used to examine the association between distance to a urologist and prostate cancer risk group (low, intermediate, high or very high/metastasis) at diagnosis for black and white patients while accounting for age, comorbidity, marital status and diagnosis year. An overall model was then used to examine the distance × race interaction effect. RESULTS: Included in analysis were 1,720 white and 531 black men. In the overall cohort the high risk cancer rate increased monotonically with distance to a urologist, including 40% for 0 to 10, 45% for 11 to 20 and 57% for greater than 20 miles. Correspondingly the low risk cancer rate decreased with longer distance. On race stratified multivariate analysis longer distance was associated with higher risk prostate cancer for white and black patients (p = 0.04 and <0.01, respectively) but the effect was larger in the latter group. The distance × race interaction term was significant in the overall model (p = 0.03). CONCLUSIONS: Longer distance to a urologist may disproportionally impact black patients. Decreasing modifiable barriers to health care access, such as distance to care, may decrease racial disparities in prostate cancer.

Phase I study of concurrent weekly docetaxel, high-dose intensity-modulated radiation therapy (IMRT) and androgen-deprivation therapy (ADT) for high-risk prostate cancer.

UNLABELLED: Study Type - Therapy (phase 1) Level of Evidence 2a What's known on the subject? and What does the study add? High-risk and locally advanced prostate cancers are difficult to cure with the standard regimen of radiation therapy (RT) with concurrent androgen-deprivation therapy (ADT). Multiple studies have explored the addition of docetaxel chemotherapy in attempt to improve patient outcomes. Prior Phase I studies have shown that docetaxel 20 mg/m(2) is a safe dose, when given concurrently with 70 Gy of radiation. But current standard RT for prostate cancer uses higher doses, and it is unclear if concurrent chemotherapy is safe with modern RT. This is a Phase I study that explored the addition of concurrent docetaxel chemotherapy to modern RT (intensity-modulated RT to 78 Gy) plus ADT. The study showed that weekly docetaxel at 20 mg/m(2) is safe with modern RT. At a median follow-up of 2.2 years, biochemical progression-free survival was 94%. This triple-therapy regimen is safe and promising for further evaluation in prospective trials. OBJECTIVE: • To evaluate in a phase I trial, the feasibility of adding concurrent weekly docetaxel chemotherapy to high-dose intensity modulated radiation therapy (IMRT) and androgen-deprivation therapy (ADT) for treatment of high-risk prostate cancer. PATIENTS AND METHODS: • Patients with high-risk prostate cancer were treated with a luteinising hormone-releasing hormone agonist (starting 2-3 months before IMRT and lasting 2 years), IMRT of 78 Gy to the prostate and seminal vesicles, and weekly docetaxel during RT. • All patients had computed tomography and bone scans to exclude metastatic disease. • A standard 3 + 3 design was used for docetaxel dose escalation. Successive patients were treated on dose levels of 10, 15, and 20 mg/m(2) of weekly docetaxel. RESULTS: • In all, 18 patients participated in the study: 15 (83%) had Gleason 8-10 disease; the other three had either clinical T3 disease and/or a prostate-specific antigen (PSA) level of >20 ng/mL. • Grade 3 diarrhoea (a defined dose-limiting toxicity, DLT) occurred in one patient in each of the first two dose levels. However, when the cohorts were expanded, no further DLT was seen. • Weekly docetaxel at 20 mg/m(2) (dose level 3) was successfully given without DLT. • No patient had grade 4 or 5 toxicity. • At a median follow-up of 2.2 years, all patients achieved a PSA nadir of <1 ng/mL, including 13 patients who had an undetectable PSA level. The 2-year biochemical progression-free survival was 94%. CONCLUSION: • A dose of 20 mg/m(2) of weekly docetaxel given concurrently with high-dose IMRT and ADT appears safe for further study in patients with high-risk prostate cancer.

A surveillance system for monitoring, public reporting, and improving minority access to cancer clinical trials.

BACKGROUND: The Institute of Medicine (IOM) has recommended that each person with cancer should have access to clinical trials, which have been associated with improving care quality and disparities. With no effective enrollment monitoring system, patterns of trial enrollment remain unclear. PURPOSE: We developed a population-based, statewide system designed to facilitate monitoring of cancer trial enrollment and targeting of future interventions to improve it. METHODS: Person-level cancer incidence data from the North Carolina Central Cancer Registry (NCCCR), person-level treatment trial accrual data from the National Cancer Institute (NCI), and county-level Area Resource Files (ARF) measures for 12 years, 1996-2007, were studied. Deidentified person-level data necessitated county-level analysis. Enrollment rates were estimated as the ratio of trial enrollment to cancer incidence for each race, gender, year, and county combination. Multivariable analysis examined factors associated with trial accrual. Sensitivity analyses examined spurious fluctuations and temporal discordance of incidence and enrollment. RESULTS: The NCI treatment trial enrollment rate was 2.39% for whites and 2.20% for minorities from 1996 to 2007, and 2.88% and 2.47%, respectively, from 2005 to 2007. Numerous counties had no minority enrollment. The 2005-2007 enrollment rates for white and minority females was 4.04% and 3.59%, respectively, and for white and minority males was 1.74% and 1.36%, respectively. Counties with a medical school or NCI Community Clinical Oncology Program (CCOP)-affiliated practice had higher trial enrollment. LIMITATIONS: We examined NCI trial accrual only - industry-sponsored and investigator-initiated trials were excluded; however, studies comprise the majority of all clinical trial participants. Delays in data availability may hinder the immediacy of population-based analyses. CONCLUSIONS: Model stability and consistency suggest that this system is effective for population-based enrollment surveillance. For North Carolina, it suggests a worsening disparity in minority trial enrollment, though our analyses elucidate targets for intervention. Regional enrollment variation suggests the importance of access to clinical research networks and infrastructure. Substantial gender differences merit further examination.
