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.

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.

Retrospective descriptive analysis of a managed care population with obesity.

OBJECTIVES: To reveal the extent of obesity in a single healthcare system and provide a blueprint for other health systems to perform similar analyses, this study describes characteristics and weight change patterns of patients classified with overweight and obesity at a large integrated delivery network (IDN) in the South-Central United States. METHODS: A descriptive, observational, retrospective study was conducted using electronic medical records and claims data. Patients were ≥18 years old, body mass index (BMI) ≥27 kg/m2, and continuously enrolled in the IDN plan for ≥6 months before and ≥12 months after the index date. Demographics, comorbidities, BMI, and weight were collected. Weight changes were assessed annually, and anti-obesity medications (AOM) use was also captured. RESULTS: A total of 36,430 eligible patients were identified. A subset of 22,712 patients was continuously enrolled for the entire study period (mean age: 57.2) and were primarily white (83.3%) and commercially insured (54.3%). Most patients were categorized as overweight (40.1%) or obesity class I (32.5%) at baseline. At years 1 and 4 post-index, patients who maintained index weight (±3%) was 56.2% and 37.0%, respectively, whereas weight gain (≥3% increase) was 23.7% and 33.3%, respectively. AOM use (1.1%) primarily consisted of phentermine-hydrochloride (n = 114, 0.5%) and orlistat (n = 115, 0.5%). CONCLUSIONS: An increasing proportion of patients gained weight over time, combined with low AOM use, emphasizing the need for weight-loss interventions in this population. Findings from this study provide a foundation for health systems to perform similar analyses.

A real-world evaluation of radium-223 in combination with abiraterone or enzalutamide for the treatment of metastatic castration-resistant prostate cancer.

INTRODUCTION: Radium-223, abiraterone, and enzalutamide have each been shown to significantly improve survival as monotherapy in patients with metastatic castration-resistant prostate cancer. However, effects of combination radium-223 plus abiraterone or enzalutamide on survival and safety remain unclear. PATIENTS AND METHODS: This single-center retrospective cohort study used electronic health record data of patients with metastatic castration-resistant prostate cancer and bone metastases who were treated with radium-223 between April 1, 2014 and February 19, 2019. Patients who received radium-223 monotherapy were compared to patients who received a combination of radium-223 plus either abiraterone or enzalutamide. The primary endpoint was overall survival. Secondary endpoints included progression-free survival, time to symptomatic skeletal event, symptomatic skeletal event-free survival, and incidence of drug-related adverse events. Time-to-event analyses were estimated by log rank tests using Kaplan-Meier curves. Hazard ratios and 95% confidence intervals were derived from Cox proportional hazards models. Chi-square tests evaluated difference in serious adverse events between the two arms. RESULTS: A total of 60 patients met inclusion criteria (n = 41 in the monotherapy arm, n = 19 in the combination arm). Differences in median overall survival were not observed (12.7 vs. 12.8 months; HR 1.15, 95% CI 0.59-2.23; P = 0.68), but median progression-free survival was significantly longer in the combination arm (7.6 vs. 4.9 months; HR 1.94, 95% CI 1.11-3.40; P = 0.02). Significant differences were not observed in time to first SSE (P = 0.97), SSE-free survival (P = 0.16), or in the overall incidence of serious adverse events (P = 0.45). CONCLUSION: Combination radium-223 plus abiraterone or enzalutamide did not improve overall survival, but prolonged progression-free survival without increasing the incidence of serious adverse events in metastatic castration-resistant prostate cancer patients with bone metastases. However, these results are limited by small numbers and patient selection inherent in retrospective analysis.

Patient and provider characteristics and outcomes associated with outpatient antibiotic overuse in acute adult bronchitis.

Nonbacterial acute bronchitis leads to many outpatient clinic visits in the US that result in an antibiotic prescription. Understanding antibiotic prescribing patterns and their clinical consequences will help improve antimicrobial stewardship efforts. A retrospective chart review was conducted to identify any correlations between patient and provider characteristics with antibiotic use in adult acute bronchitis (AAB) and to compare the clinical outcomes and rates of health care utilization between those who did and did not receive antibiotics. Study participants included adults with uncomplicated AAB seen by family medicine or internal medicine, specialty, and mid-level practitioners in a Baylor Scott & White Health outpatient facility. Phase 1 investigated whether prescribing rates varied by provider- or patient-level characteristics. Phase 2 compared clinical outcomes and health care utilization between patients who received an antibiotic versus those who did not receive an antibiotic for AAB. Among 35,383 visits for AAB, 81.4% resulted in a prescription for an antibiotic. Physicians >35 years of age and internal and family medicine physicians were more likely to prescribe antibiotics. Health care utilization rates did not differ between cohorts. The number of Clostridium difficile events was negligible.

Cardiovascular Outcomes Among Patients with Type 2 Diabetes Newly Initiated on Sodium-Glucose Cotransporter-2 Inhibitors, Glucagon-Like Peptide-1 Receptor Agonists, and Other Antidiabetic Medications.

BACKGROUND: Cardiovascular disease (CVD) remains the most prevalent cause of morbidity and mortality in patients with type 2 diabetes (T2D) and is a primary driver for health care costs associated with diabetes management. Sodium-glucose cotransporter-2 inhibitors (SGLT-2is) and glucagon-like peptide-1 receptor agonists (GLP-1 RAs) have demonstrated significant reductions in cardiovascular endpoints in clinical trials compared with placebo. However, it is uncertain whether these findings can be applied to the broader T2D population because these trials specifically included high-risk patients with established CVD. OBJECTIVE: To evaluate and compare cardiovascular outcomes among adults with T2D newly initiated on SGLT-2is, GLP-1 RAs, and other antidiabetic medications (oADMs) in a real-world setting. METHODS: This retrospective new-user cohort study used administrative claims and electronic health record data from an integrated delivery network in Texas. Patients aged ≥18 years with T2D and ≥1 prescription claim for an SGLT-2i, a GLP-1 RA, or an oADM filled between April 2013 and December 2018 were included. Patients were divided into three 1:1 propensity-matched groups according to index medication identified. Primary outcomes were heart failure hospitalization and a composite end-point of myocardial infarction, stroke, unstable angina, or coronary revascularization. Cox proportional hazards regression was used to compare cumulative incidence of all outcome variables. RESULTS: Among 9,477 patients, 1,134 were initiated on SGLT-2is, 1,072 on GLP-1 RAs, and 7,271 on oADMs. Patients initiating SGLT-2is versus oADMs had significantly lower risk of the composite endpoint (HR = 0.64, 95% CI = 0.46-0.90), heart failure hospitalization (HR = 0.56, 95% CI = 0.39-0.81), and unstable angina requiring hospitalization (HR = 0.56, 95% CI = 0.39-0.81). Patients initiating GLP-1 RAs compared with oADMs had significantly lower risk of the composite endpoint (HR = 0.71, 95% CI = 0.52-0.98) and unstable angina requiring hospitalization (HR = 0.60, 95% CI = 0.41-0.86). No differences in cardiovascular outcomes were found between SGLT-2is and GLP-1 RAs. CONCLUSIONS: Both SGLT-2is and GLP-1 RAs showed significant reductions in the composite outcome and unstable angina requiring hospitalization versus oADMs. However, only SGLT-2is were associated with a lower risk for heart failure hospitalizations. Nevertheless, cardiovascular outcomes were similar between SGLT-2is and GLP-1 RAs. DISCLOSURES: No outside funding supported this study. The authors have no conflicts of interest to report.

Pilot Study of [18F] Fluorodeoxyglucose Positron Emission Tomography (FDG-PET)/Magnetic Resonance Imaging (MRI) for Staging of Muscle-invasive Bladder Cancer (MIBC).

INTRODUCTION: Computed tomography (CT) has limited diagnostic accuracy for staging of muscle-invasive bladder cancer (MIBC). [18F] Fluorodeoxyglucose positron emission tomography (FDG-PET)/magnetic resonance imaging (MRI) is a novel imaging modality incorporating functional imaging with improved soft tissue characterization. This pilot study evaluated the use of preoperative FDG-PET/MRI for staging of MIBC. PATIENTS AND METHODS: Twenty-one patients with MIBC with planned radical cystectomy were enrolled. Two teams of radiologists reviewed FDG-PET/MRI scans to determine: (1) presence of primary bladder tumor; and (2) lymph node involvement and distant metastases. FDG-PET/MRI was compared with cystectomy pathology and computed tomography (CT). RESULTS: Eighteen patients were included in the final analysis, most (72.2%) of whom received neoadjuvant chemotherapy. Final pathology revealed 10 (56%) patients with muscle invasion and only 3 (17%) patients with lymph node involvement. Clustered analysis of FDG-PET/MRI radiology team reads revealed a sensitivity of 0.80 and a specificity of 0.56 for detection of the primary tumor with a sensitivity of 0 and a specificity of 1.00 for detection of lymph node involvement when compared with cystectomy pathology. CT imaging demonstrated similar rates in evaluation of the primary tumor (sensitivity, 0.91; specificity, 0.43) and lymph node involvement (sensitivity, 0; specificity, 0.93) when compared with pathology. CONCLUSIONS: This pilot single-institution experience of FDG-PET/MRI for preoperative staging of MIBC performed similar to CT for the detection of the primary tumor; however, the determination of lymph node status was limited by few patients with true pathologic lymph node involvement. Further studies are needed to evaluate the potential role for FDG-PET/MRI in the staging of MIBC.

Management of Androgen Deprivation Therapy-Associated Hot Flashes in Men With Prostate Cancer.

PROBLEM IDENTIFICATION: To determine best practices for managing hot flashes associated with androgen deprivation therapy (ADT) in men with prostate cancer. LITERATURE SEARCH: The CINAHL®, Embase®, PsycINFO®, PubMed®, and Scopus® databases were used to identify randomized controlled trials (RCTs) and quasiexperimental studies published between January 1994 and June 2018. DATA EVALUATION: Using the Cochrane Handbook for Systematic Reviews of Interventions, the authors reviewed 15 studies examining the effects of pharmacologic or complementary and alternative medicine interventions on ADT-associated hot flashes in men with prostate cancer. SYNTHESIS: Pharmacologic interventions (e.g., cyproterone, medroxyprogesterone, megestrol acetate) showed some promise for reducing hot flashes but were associated with side effects and risks. Acupuncture demonstrated potential benefit in reducing hot flashes without side effects. IMPLICATIONS FOR RESEARCH: Evidence is insufficient to support interventions for ADT-associated hot flashes in men with prostate cancer. Future RCTs should be sufficiently powered, include a control group, and use standardized outcome measures.

Guidelines impact cholesterol management.

BACKGROUND: Previous research demonstrates increased utilization of high-intensity statins, but unchanged low-density lipoprotein cholesterol (LDL-C) levels, immediately after the 2013 American College of Cardiology (ACC) and the American Heart Association (AHA) guideline release. OBJECTIVE: The objective of this study was to determine achievement of statin therapy goals in patients with atherosclerotic cardiovascular disease (ASCVD) before and up to 4 years after the 2013 ACC/AHA guideline release compared with LDL-C goals of <70 mg/dL and <100 mg/dL previously recommended by other professional societies. METHODS: The single-system cohort study used medical records, laboratory results, and claims data (November 2012-October 2017) of adults with ≥1 claim for a statin, ≥1 ASCVD diagnosis in propensity score-matched analyses. RESULTS: Among 1938 patients (mean age 70 ± 11, 48% female) with ASCVD, the percentage on high-intensity statin therapy significantly increased over time: 24% in 2013, 34% 2014, 42% 2015, and 49% 2016 (P < .0001). The increase in high-intensity statin use was 13 to 22% higher among patients managed by subspecialists (cardiologist and endocrinologists) compared with those managed by primary care providers. Mean LDL-C level was slightly, but not significantly, lower in 2013 (80 mg/dL) than in other years: 85 mg/dL in 2014, 83 mg/dL in 2015, and 82 mg/dL in 2016. The proportion of patients reaching LDL-C goals ranged from 51% to 56% for the <70 mg/dL target and 77% to 85% for the <100 mg/dL target over time. CONCLUSION: High-intensity statin use among secondary prevention patients increased significantly immediately after the 2013 ACC/AHA guidelines release, primarily in those managed by subspecialists. However, the mean LDL-C and the proportion of patients reaching LDL-C < 70 mg/dL and < 100 mg/dL remain unchanged across comparison cohorts.

Patient-reported Quality of Life Following Stereotactic Body Radiotherapy and Conventionally Fractionated External Beam Radiotherapy Compared with Active Surveillance Among Men with Localized Prostate Cancer.

BACKGROUND: Evidence supporting the efficacy of stereotactic body radiotherapy (SBRT) for localized prostate cancer is accumulating, but comparative studies of patient-reported quality of life (QOL) following SBRT versus conventionally fractionated external beam radiotherapy (EBRT) or active surveillance (AS) are limited. OBJECTIVE: To compare QOL of patients pursuing SBRT and EBRT versus AS. DESIGN, SETTING, AND PARTICIPANTS: A population-based cohort of 680 men with newly diagnosed localized prostate cancer was prospectively enrolled from 2011 to 2013. INTERVENTION: SBRT, EBRT without androgen deprivation therapy, or AS. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: QOL was prospectively assessed before treatment (baseline), and at 3, 12, and 24mo after treatment using the validated Prostate Cancer Symptom Indices, which contain four domains: sexual dysfunction, urinary obstruction/irritation, urinary incontinence, and bowel problems. Propensity weighting via logistic regression models was used to balance baseline characteristics, and the mean QOL scores of EBRT and SBRT patients were compared against AS patients as the control group. RESULTS AND LIMITATIONS: Compared with AS patients, EBRT patients had worse urinary obstructive/irritative symptoms and sexual dysfunction at 3mo, and worse bowel symptoms at 3 and 24mo. SBRT patients had similar scores as AS patients in all domains and across all time points; however, due to small sample size, worse sexual function and urinary incontinence in SBRT patients cannot be ruled out. Further research is needed to assess long-term outcomes. CONCLUSIONS: In a nonrandomized cohort of men with localized prostate cancer, SBRT appeared to result in favorable QOL results through 2yr of follow-up, but worse sexual function and urinary incontinence compared with AS cannot be ruled out completely. Larger studies with longer follow-up are needed to confirm these findings. PATIENT SUMMARY: Stereotactic body radiotherapy (SBRT) and active surveillance appear to have similar quality of life outcomes through 2yr, although worse sexual function and urinary incontinence from SBRT cannot be ruled out completely.

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.

Implementing a small media intervention to increase colorectal cancer screening in primary care clinics.

Colorectal cancer (CRC) is one of the most common cancers in the USA. In 2017, an estimated 135,420 people were diagnosed with CRC and 50,260 people died from CRC. Several screening modalities are recommended by the United States Preventive Services Task Force (USPSTF), including annual stool tests that are usually completed at home and under-used compared with colonoscopy despite stated patient preferences for an alternative to colonoscopy. The Community Preventive Services Task Force recommends use of small media interventions (SMIs) to increase CRC screening and calls for a greater understanding of its independent impact on screening participation. This study tested whether a SMI increased the likelihood of participant return of a USPSTF recommended Fecal Immunochemical Test (FIT). In total, 804 individuals participated in a two-group, prospective randomized controlled trial. Descriptive statistics with chi-square tests compared differences in participant characteristics and return rates. Multivariable log-binomial modeling estimated combined effects of patient characteristics with FIT return rates. No differences in return rates were observed overall or by participant characteristics other than the year of enrollment. A multivariable model controlling for all covariates, found gender, insurance type, and regular place for healthcare to be significantly associated with return rates. Receipt of the SMI did not independently increase overall return rates but it may have improved the ease of completing the FIT by some participants, particularly women, those with insurance, and those with a regular place for healthcare.

Race and Time to Receipt of Androgen Deprivation Therapy Among Men With Metastatic Prostate Cancer.

BACKGROUND: The Medicare Modernization Act (MMA) drastically reduced reimbursement for androgen deprivation therapy (ADT) in 2005. One unintended consequence of the MMA may be an increase in the racial disparities in receipt of ADT. Given these policy changes, it becomes increasingly important to assess racial disparities in timely receipt of ADT. METHODS: The purpose of this study is to evaluate the associations between race and median time to receipt of ADT among men with metastatic prostate cancer before and after the passage of the MMA. A population-based retrospective cohort was created from the Surveillance, Epidemiology, and End Results-Medicare. RESULTS: A total of 1,846 African-American and 9,462 Caucasian men diagnosed with metastatic prostate cancer from 2000 through 2011 were included. An accelerated failure time regression model was used to examine factors associated with racial differences in median time to receipt of ADT. Results indicate that African-American men had a longer median time to receipt of ADT both before the MMA (Time Ratio (TR): 1.15; 95% Confidence Interval (CI) [1.05, 1.27]) and after the MMA (TR: 1.29; 95% CI [1.10, 1.53]) as compared to Caucasian men. In addition to race, men residing in South had longer median time to receipt of ADT (TR: 1.26, 1.52; 95% CI [1.01, 1.52; 1.24, 1.87] before and after MMA, respectively) compared to the Northeast region. CONCLUSION: Considering the palliative benefits of ADT, it is important to develop effective strategies to address racial differences in receipt of treatment for metastatic prostate cancer.

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.

Prostate Cancer Patient Characteristics Associated With a Strong Preference to Preserve Sexual Function and Receipt of Active Surveillance.

Background: Men with early-stage prostate cancer have multiple options that have similar oncologic efficacy but vary in terms of their impact on quality of life. In low-risk cancer, active surveillance is the option that best preserves patients' sexual function, but it is unknown if patient preference affects treatment selection. Our objectives were to identify patient characteristics associated with a strong preference to preserve sexual function and to determine whether patient preference and baseline sexual function level are associated with receipt of active surveillance in low-risk cancer. Methods: In this population-based cohort of men with localized prostate cancer, baseline patient-reported sexual function was assessed using a validated instrument. Patients were also asked whether preservation of sexual function was very, somewhat, or not important. Prostate cancer disease characteristics and treatments received were abstracted from medical records. A modified Poisson regression model with robust standard errors was used to compute adjusted risk ratio (aRR) estimates. All statistical tests were two-sided. Results: Among 1194 men, 52.6% indicated a strong preference for preserving sexual function. Older men were less likely to have a strong preference (aRR = 0.98 per year, 95% confidence interval [CI] = 0.97 to 0.99), while men with normal sexual function were more likely (vs poor function, aRR = 1.59, 95% CI = 1.39 to 1.82). Among 568 men with low-risk cancer, there was no clear association between baseline sexual function or strong preference to preserve function with receipt of active surveillance. However, strong preference may differnetially impact those with intermediate baseline function vs poor function (Pinteraction = .02). Conclusions: Treatment choice may not always align with patients' preferences. These findings demonstrate opportunities to improve delivery of patient-centered care in early prostate cancer.

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.

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.

Comparison of Patient Report and Medical Records of Comorbidities: Results From a Population-Based Cohort of Patients With Prostate Cancer.

IMPORTANCE: The comorbid conditions of patients with cancer affect treatment decisions, which in turn affect survival and health-related quality-of-life outcomes. Comparative effectiveness research studies must account for these conditions via medical record abstraction or patient report. OBJECTIVE: To examine the agreement between medical records and patient reports in assessing comorbidities. DESIGN, SETTING, AND PARTICIPANTS: Patient-reported information and medical records were prospectively collected as part of the North Carolina Prostate Cancer Comparative Effectiveness & Survivorship Study, a population-based cohort of 881 patients with newly diagnosed localized prostate cancer enrolled in the North Carolina Central Cancer Registry from January 1, 2011, through June 30, 2013. The presence or absence of 20 medical conditions was compared based on patient report vs abstraction of medical records. MAIN OUTCOMES AND MEASURES: Agreement between patient reports and medical records for each condition was assessed using the κ statistic. Subgroup analyses examined differences in κ statistics based on age, race, marital status, educational level, and income. Logistic regression models for each condition examined factors associated with higher agreement. RESULTS: A total of 881 patients participated in the study (median age, 65 years; age range, 41-80 years; 633 white [71.9%]). In 16 of 20 conditions, there was agreement between patient reports and medical records for more than 90% of patients; agreement was lowest for hyperlipidemia (68%; κ = 0.36) and arthritis (66%; κ = 0.14). On multivariable analysis, older age (≥70 years old) was significantly associated with lower agreement for myocardial infarction (odds ratio [OR], 0.31; 95% CI, 0.12-0.80), cerebrovascular disease (OR, 0.10; 95% CI, 0.01-0.78), coronary artery disease (OR, 0.37; 95% CI, 0.20-0.67), arrhythmia (OR, 0.44; 95% CI, 0.25-0.79), and kidney disease (OR, 0.18; 95% CI, 0.06-0.52). Race and educational level were not significantly associated with κ in 18 of 19 modeled conditions. CONCLUSIONS AND RELEVANCE: Overall, patient reporting provides information similar to medical record abstraction without significant differences by patient race or educational level. Use of patient reports, which are less costly than medical record audits, is a reasonable approach for observational comparative effectiveness research.
