- Abstract
BACKGROUND: ASPirin in Reducing Events in the Elderly, a randomized, double-blind, placebo-controlled trial of daily low-dose aspirin (100 mg) in older adults, showed an increase in all-cause mortality, primarily due to cancer. In contrast, prior randomized controlled trials, mainly involving younger individuals, demonstrated a delayed cancer benefit with aspirin. We now report a detailed analysis of cancer incidence and mortality. METHODS: 19 114 Australian and US community-dwelling participants aged 70 years and older (US minorities 65 years and older) without cardiovascular disease, dementia, or physical disability were randomly assigned and followed for a median of 4.7 years. Fatal and nonfatal cancer events, a prespecified secondary endpoint, were adjudicated based on clinical records. RESULTS: 981 cancer events occurred in the aspirin and 952 in the placebo groups. There was no statistically significant difference between groups for all incident cancers (hazard ratio [HR] = 1.04, 95% confidence interval [CI] = 0.95 to 1.14), hematological cancer (HR = 0.98, 95% CI = 0.73 to 1.30), or all solid cancers (HR = 1.05, 95% CI = 0.95 to 1.15), including by specific tumor type. However, aspirin was associated with an increased risk of incident cancer that had metastasized (HR = 1.19, 95% CI = 1.00 to 1.43) or was stage 4 at diagnosis (HR = 1.22, 95% CI = 1.02 to 1.45), and with higher risk of death for cancers that presented at stages 3 (HR = 2.11, 95% CI = 1.03 to 4.33) or 4 (HR = 1.31, 95% CI = 1.04 to 1.64). CONCLUSIONS: In older adults, aspirin treatment had an adverse effect on later stages of cancer evolution. These findings suggest that in older persons, aspirin may accelerate the progression of cancer and, thus, suggest caution with its use in this age group.

- Abstract
Background: Cancer survivors can be at risk of cardiovascular disease (CVD) because of either their malignancy or its treatment. Although studies linking cancer and CVD exist, few examine risk in older adults, the impact of cancer treatment, or the effect of aspirin on reducing risk in this cohort., Methods: The authors conducted a secondary analysis of the Aspirin in Reducing Events in the Elderly (ASPREE) trial to investigate the impact of cancer and cancer treatment on a composite CVD end point comprising hospitalization for heart failure (HHF), myocardial infarction (MI), and stroke., Results: Of 15,454 Australian and US ASPREE participants, 1392 had an incident cancer diagnosis. Rates of CVD were greater in the cancer risk-set compared to the cancer-free risk-set (20.8 vs. 10.3 events per 1000 person-years; incidence rate ratio, 2.03; 95% confidence interval, 1.51-2.66), with increased incidence seen across MI, HHF, overall stroke, and ischemic stroke. Increased incidence remained after adjustment for clinically significant risk factors for CVD. Incidence was greatest in metastatic, hematological, and lung cancer. Chemotherapy was associated with increased risk of CVD. Similar rates of CVD were seen across aspirin and placebo groups., Conclusions: Incidence of CVD, including MI, HHF, and ischemic stroke, was increased in older adults with cancer. Aspirin did not impact CVD incidence. Risk may be higher in those with metastatic, hematological, and lung cancer, and following chemotherapy., (© 2024 The Author(s).

- Abstract
Commission on Cancer (CoC) accreditation certifies facilities provide quality care. We assessed differences among patients who do and do not visit CoC facilities using Pennsylvania Cancer Registry data linked to facility records for patients diagnosed with cancer between 2018 and 2019 (n = 87 472). Predicted probabilities from multivariable logistic regression indicated patients in the most advantaged Area Deprivation Index quartiles were more likely to visit CoC facilities (78.0%, 95% confidence interval [CI] = 77.5% to 78.6%) compared with other quartiles. Urban patients (74.1%, 95% CI = 73.8% to 74.4%) were more likely than rural to be seen at a CoC facility (62.7%, 95% CI = 61.2% to 64.2%) as were Hispanic patients (88.0%, 95% CI = 86.7% to 89.3%) and non-Hispanic Black patients (79.1%, 95% CI = 78.1% to 80.0%) compared with White patients (72.0%, 95% CI = 71.7% to 72.4%). Differences in demographics suggest CoC data may underrepresent some groups, including low-income and rural patients., (© The Author(s) 2023. Published by Oxford University Press.)

- Abstract
Purpose: Extending adjuvant endocrine therapy (ET) beyond the standard 5 years offers added protection against late breast cancer recurrences in women with early-stage hormone receptor-positive (HR +) breast cancer. Little is known about treatment persistence to extended ET (EET) and the role that genomic assays may play. In this study, we evaluated persistence to EET in women who had Breast Cancer Index (BCI) testing., Methods: Women with stage I-III HR + breast cancer who had BCI testing after at least 3.5 years of adjuvant ET and ≥ 7 years of follow-up after diagnosis were included (n = 240). Data on medication persistence was based on prescriptions in the electronic health record., Results: BCI predicted 146 (61%) patients to have low - BCI (H/I)-low - and 94 (39%) patients to have high likelihood of benefit from EET (BCI (H/I)-high). Continuation of ET after BCI occurred in 76 (81%) (H/I)-high and 39 (27%) (H/I)-low patients. Non-persistence rates were 19% in the (H/I)-high and 38% in the (H/I)-low group. The most common reason for non-persistence was intolerable side effects. Patients on EET underwent more DXA bone density scans than those who stopped ET at 5 years (mean 2.09 versus 1.27; p < 0.001). At a median follow-up of 10 years from diagnosis, there were 6 metastatic recurrences., Conclusions: In patients who continued ET after BCI testing, the rates of persistence to EET were high, particularly in patients with predicted high likelihood of benefit from EET. Use of EET is associated with increased use of DXA scans., (© 2023. The Author(s).)

- Abstract
Introduction: Cancer treatment planning in older adults is complex and requires careful balancing of survival, quality of life benefits, and risk of treatment-related morbidity and toxicity. As a result, treatment selection in this cohort tends to differ from that for younger patients. However, there are very few studies describing cancer treatment patterns in older cohorts., Methods: We used data from the ASPirin in Reducing Events in the Elderly (ASPREE) trial and the ASPREE Cancer Treatment Substudy (ACTS) to describe cancer treatment patterns in older adults. We used a multivariate logistic regression model to identify factors affecting receipt of treatment., Results: Of 1893 eligible Australian and United States (US) participants with incident cancer, 1569 (81%) received some form of cancer treatment. Non-metastatic breast cancers most frequently received treatment (98%), while haematological malignancy received the lowest rates of treatment (60%). Factors associated with not receiving treatment were older age (OR 0.94, 95% CI 0.91-0.96), residence in the US (OR 0.34, 95% CI 0.22-0.54), smoking (OR 0.57, 95% CI 0.40-0.81), and diabetes (OR 0.56, 95% CI 0.39-0.80). After adjustment for treatment patterns in sex-specific cancers, sex did not impact receipt of treatment., Conclusions: This study is one of the first describing cancer treatment patterns and factors affecting receipt of treatment across common cancer types in older adults. We found that most older adults with cancer received some form of cancer treatment, typically surgery or systemic therapy, although this varied by factors such as cancer type, age, sex, and country of residence.

- Abstract
Purpose of Review: Cardiovascular disease is long-term complication of both cancer and anti-cancer treatment and can have significant ramifications for health-related quality of life and mortality. This narrative review explores the current evidence linking cardiovascular disease and cancer, as well as exploring strategies for the prevention and management of cardiovascular disease, and outlines future opportunities in the field of cardio-oncology., Recent Findings: Cancer confers risk for various cardiovascular diseases including heart failure, cardiomyopathy, arrhythmia, coronary heart disease, stroke, venous thromboembolism, and valvular heart disease. Cancer treatment, in particular agents such as platinum-based chemotherapy, anthracyclines, hormonal treatments, and thoracic radiotherapy, further increases risk. While cardiovascular disease can be identified early and effectively managed in cancer survivors, cardiovascular screening and management does not typically feature in routine long-term cancer care of adult cancer survivors. Cancer and cancer treatment can accelerate the development of cardiovascular disease. Further research into screening and management strategies for cardiovascular disease, along with evidence-based guidelines, is required to ensure adult cancer survivors receive appropriate long-term care., (© 2022.

- Abstract
It is without question that the Internet has democratized access to medical information, with estimates that 70% of the American population use it as a resource, particularly for cancer-related information. Such unfettered access to information has led to an increase in health misinformation. Fortunately, the data indicate that health care professionals remain among the most trusted information resources. Therefore, understanding how the Internet has changed engagement with health information and facilitated the spread of misinformation is an important task and challenge for cancer clinicians. In this review, we perform a meta-synthesis of qualitative data and point toward empirical evidence that characterizes misinformation in medicine, specifically in oncology. We present this as a call to action for all clinicians to become more active in ongoing efforts to combat misinformation in oncology.

- Abstract
The use of social media continues to increase in health care and academia. Health care practice, particularly the oncologic field, is constantly changing because of new knowledge, evidence-based research, clinical trials, and government policies. Therefore, oncology trainees and professionals continue to strive to stay up-to-date with practice guidelines, research, and skills. Although social media as an educational and professional development tool is no longer completely new to medicine and has been embraced, it is still under-researched in terms of various outcomes. Social media plays several key roles in professional development and academic advancement. We reviewed the literature to evaluate how social media can be used for professional development and academic promotion of oncology professionals.

- Abstract
There are well-documented differences in breast cancer treatment by insurance status. Insurance expansions provide a context to assess the relationship between insurance and patterns of breast cancer care. We examine the association of Massachusetts health reform with use of breast conserving surgery, reconstruction, and adjuvant radiation using data from the Massachusetts Cancer Registry and Surveillance Epidemiology and End Results registries for 2001-2013 and a difference-in-differences approach. We observe statistically significant increases in breast conserving surgery among nonelderly women in Massachusetts relative to trends in states and age groups not affected by health reform. We also observe relative increases in reconstruction and adjuvant radiation, though trends in these outcomes were not the same across states prior to reform, limiting our ability to draw conclusions about the relationship between reform and these outcomes. Our results suggest that health reform was associated with some improvements in breast cancer treatment.

- Abstract
A decline in functional status, an individual's ability to perform the normal activities required to maintain adequate health and meet basic needs, is part of normal ageing. Functional decline, however, appears to be accelerated in older patients with cancer. Such decline can occur as a result of a cancer itself, cancer treatment-related factors, or a combination of the two. The accelerated decline in function seen in older patients with cancer can be slowed, or even partly mitigated through routine assessments of functional status and timely interventions where appropriate. This is particularly important given the link between functional decline and impaired quality of life, increased mortality, comorbidity burden, and carer dependency. However, a routine assessment of and the use of interventions for functional decline do not typically feature in the long-term care of cancer survivors. This review outlines the link between cancer and subsequent functional decline, as well as potential underlying mechanisms, the tools that can be used to assess functional status, and strategies for its prevention and management in older patients with cancer.

- Abstract
Background: Given limited evidence on opioid prescribing among patients receiving treatment for cancer during the ongoing opioid epidemic, our objective was to assess predictors of and trends in opioid receipt during cancer treatment, including how patterns differ by type of cancer., Methods: Using cancer registry data, we identified patients with a first lifetime primary diagnosis of breast, colorectal, or lung cancer from 2013 to 2017 who underwent treatment within a large cancer center network. Cancer registry data were linked to electronic health record information on opioid prescriptions. We examined predictors of and trends in receipt of any opioid prescription within 12 months of cancer diagnosis., Results: The percentage of patients receiving opioids varied by cancer type: breast cancer, 35% (1,996/5,649); colorectal, 37% (776/2,083); lung, 47% (1,259/2,654). In multivariable analysis, opioid use in the year before cancer diagnosis was the factor most strongly associated with receipt of opioids after cancer diagnosis, with 4.90 (95% CI, 4.10-5.86), 5.09 (95% CI, 3.88-6.69), and 3.31 (95% CI, 2.68-4.10) higher odds for breast, colorectal, and lung cancers, respectively. We did not observe a consistent decline in opioid prescribing over time, and trends differed by cancer type., Conclusions: Our findings suggest that prescription of opioids to patients with cancer varies by cancer type and other factors. In particular, patients are more likely to receive opioids after cancer diagnosis if they were previously exposed before diagnosis, suggesting that pain among patients with cancer may commonly include non-cancer-related pain. Heterogeneity and complexity among patients with cancer must be accounted for in developing policies and guidelines aimed at addressing pain management while minimizing the risk of opioid misuse.

- Abstract
Age is one of the most important risk factors for the development of breast cancer. Nearly a third of all breast cancer cases occur in older women (aged ≥70 years), with most cases being oestrogen receptor-positive (ER+). Such tumours are often indolent and unlikely to be the ultimate cause of death for older women, particularly when considering other comorbidities. This Review focuses on unique clinical considerations for screening, detection, and treatment regimens for older women who develop ER+ breast cancers-specifically, we focus on recent trends for de-implementation of screening, staging, surgery, and adjuvant therapies along the continuum of care. Additionally, we also review emerging basic and translational research that will further uncover the unique underlying biology of these tumours, which develop in the context of systemic age-related inflammation and changing hormone profiles. With prevailing trends of clinical de-implementation, new insights into mechanistic biology might provide an opportunity for precision medicine approaches to treat patients with well tolerated, low-toxicity agents to extend patients' lives with a higher quality of life, prevent tumour recurrences, and reduce cancer-related burdens.

- Abstract
Background: Among breast cancer populations, exercise interventions resulted in positive but relatively small improvements on fatigue, which may be due to insensitive measures of global fatigue. Perceived fatigability-whole-body tiredness anchored to standardized tasks/activities of a specific intensity and duration-may help to detect effective exercise interventions reducing fatigue in oncology. We examined whether perceived physical fatigability improved after an exercise intervention., Methods: This single center randomized clinical trial of 49 breast cancer survivors was conducted from 2015 to 2017, among which 41 participants (22 = exercise, 19 = control) completed the trial and reported their perceived physical fatigability at the first (Visit 1) and the last visit (Visit 3) over 6-14 weeks. Perceived physical fatigability was measured using the 10-item, self-administered Pittsburgh Fatigability Scale (PFS) scored 0-50. The mean differences of perceived physical fatigability between Visit 3 and Visit 1 were computed and compared by intervention groups using two sample t test., Results: Among the 41 women in the study (mean age 54.9 ± 9.8 years; 80% white), sociodemographic, clinical characteristics and baseline fatigue level were similar by intervention groups, except for antiestrogen use. Post-intervention changes (mean ∆ ± SE) of PFS Physical scores were greater in the exercise group (- 4.4 ± 1.4; - 22.5%) than the control group (0.2 ± 1.4; + 1.0%) (p = .022)., Conclusion: The PFS captured a reduction in fatigue after the exercise intervention among breast cancer survivors. These findings aid mounting efforts to reduce fatigue in oncology by introducing a more sensitive instrument to measure perceived physical fatigability to better evaluate patient-reported outcomes in future cancer trials., Trial Registration: Clinicaltrials.gov identifier: NCT02770781., (© 2021.

- Abstract
Purpose: Exercise is important to address physical and emotional effects of breast cancer treatment. This study examines effects of a personal trainer led exercise intervention on physical activity levels, physical function and quality of life (QoL) in breast cancer survivors., Methods: Women post active breast cancer treatment were recruited from 2015 to 2017, randomized to immediate exercise or wait-list control, and received three personal training sessions for up to 30 weeks. Physical activity and function were assessed by pedometer, and tests of endurance, strength, and flexibility. Self-reported physical activity, physical activity self-efficacy, and QoL were also assessed., Results: 60 women were randomized to immediate intervention (n = 31) or wait-list control (n = 29). Subjects were aged (mean ± SD) 56 ± 10 years. On the endurance test, the exercise group significantly improved (increase of 18 ± 20 steps vs control 9 ± 12 steps) (p = 0.036). On the strength test, the exercise group significantly improved (increase of 4 ± 3 curls vs control 1 ± 3 curls) (p = 0.002). After intervention, change (mean ∆ ± SD) in the FACT-ES physical well-being subscale score was 1 ± 2 in the exercise group and - 1 ± 2 in the control group (p = 0.023). Improvement in Self-efficacy and Physical Activity (SEPA) score was significant with a change (mean ∆ ± SD) of 2 ± 5 for exercise vs 0 ± 5 for control (p = 0.047). The number of steps/day, back scratch test, weight, and self-reported physical activity did not significantly improve with intervention., Conclusions: The intervention yielded significant improvements in endurance and strength but not physical activity or quality of life., Implications for Cancer Survivors: Future efforts to explore feasible ways to support patient's physical activity efforts need to be undertaken.

- Abstract
Background: Socioeconomic differences in receipt of adjuvant treatment contribute to persistent disparities in breast cancer (BCA) outcomes, including survival. Adjuvant endocrine therapy (AET) substantially reduces recurrence risk and is recommended by clinical guidelines for nearly all women with hormone receptor-positive non-metastatic BCA. However, AET use among uninsured or underinsured populations has been understudied. The health reform implemented by the US state of Massachusetts in 2006 expanded health insurance coverage and increased the scope of benefits for many with coverage. This study examines changes in the initiation of AET among BCA patients in Massachusetts after the health reform., Methods: We used Massachusetts Cancer Registry data from 2004 to 2013 for a sample of estrogen receptor (ER)-positive BCA surgical patients aged 20-64 years. We estimated multivariable regression models to assess differential changes in the likelihood initiating AET after Massachusetts health reform by area-level income, comparing women from lower- and higher-income ZIP codes in Massachusetts., Results: There was a 5-percentage point (p-value< 0.001) relative increase in the likelihood of initiating AET among BCA patients aged 20-64 years in low-income areas, compared to higher-income areas, after the reform. The increase was more pronounced among younger patients aged 20-49 years (7.1-percentage point increase)., Conclusions: The expansion of health insurance in Massachusetts was associated with a significant relative increase in the likelihood of AET initiation among women in low-income areas compared with those in high-income areas. Our results suggest that expansions of health insurance coverage and improved access to care can increase the number of eligible patients initiating AET and may ameliorate socioeconomic disparities in BCA outcomes.

- Abstract
Background: This study sought to determine if increased access to health insurance following the Affordable Care Act (ACA) resulted in an increased proportion of early-stage breast cancer diagnosis among women in Pennsylvania, particularly minorities, rural residents, and those of lower socioeconomic status. Materials and Methods: Data on 35,735 breast cancer cases among women 50-64 and 68-74 years of age in Pennsylvania between 2010 and 2016 were extracted from the Pennsylvania Cancer Registry and analyzed in 2019. Women 50-64 years of age were subdivided by race/ethnicity, area of residence, and socioeconomic status as measured by area deprivation index (ADI). We compared the proportions of early-stage breast cancer diagnosis pre-ACA (2010-2013) and post-ACA (2014-2016) for all women 50-64 years of age to all women 68-74 years of age. This comparison was also made between paired sociodemographic subgroups for women 50-64 years of age. Multivariable logistic regression models were constructed to assess how race, area of residence, ADI, and primary care physician (PCP) density interacted to impact breast cancer diagnosis post-ACA. Results: The proportion of early-stage breast cancer diagnosis increased by 1.71% post-ACA among women 50-64 years of age ( p < 0.01), whereas women 68-74 years of age saw no change. Multivariable logistic regression analysis demonstrated that minority women had lower odds of early-stage breast cancer diagnosis pre-ACA, but not post-ACA, when controlling for ADI. Meanwhile, increased area-level socioeconomic advantage was associated with higher odds of being diagnosed with early-stage breast cancer pre- and post-ACA irrespective of controlling for race, area of residence, or PCP density. Conclusions: Enhanced access to health insurance under the ACA was associated with an increased proportion of early-stage breast cancer diagnosis in Pennsylvanian women 50-64 years of age and may have reduced racial, but not socioeconomic, disparities in breast cancer diagnosis.

- Abstract
Recent cancer care delivery models and clinical practice guidelines have expanded the role of primary care providers (PCPs) in routine follow-up of cancer survivors. We conducted a cross-sectional survey of PCPs affiliated with a large healthcare system to (1) examine practices, attitudes, and beliefs regarding preparedness to provide survivorship care and (2) explore predictors of confidence managing cancer survivors. We distributed a self-administered online survey to 1069 clinical affiliates providing primary care services within the University of Pittsburgh Medical Center system. Associations between PCPs' professional characteristics and attitudes and preparedness were evaluated. Multiple logistic regression explored predictors of confidence monitoring common cancer treatment-related symptoms. One hundred twenty-seven eligible PCPs responded. The sample was split between academic and community practice (48.0% vs. 52.0%, respectively), predominantly comprised of physicians (81.8%), and 64.6% had > 15 years direct patient care experience. The majority agreed that PCPs play a valuable role in surveillance and adverse event monitoring in survivors, though less than 25% felt their professional training prepared them to perform each of these domains. Physicians were significantly more likely than advanced practice providers to be among the 65% of PCPs who were confident monitoring ≥ 1 symptom in each of the 5 evaluated symptom clusters (OR 3.6, 95% CI 1.2-10.8). PCPs appear willing to assume an enhanced role in cancer survivorship care but feel unprepared to do so. Enhanced training and dissemination of clinical practice guidelines are needed to facilitate effective implementation of PCP-delivered survivorship care.

- Abstract
Background: This study examines the expansion of health insurance coverage in Massachusetts under state health reform as a natural experiment to investigate whether expanded insurance coverage reduced the likelihood of advanced stage colorectal cancer (CRC) and breast cancer (BCA) diagnosis., Methods: Our study populations include CRC or BCA patients aged 50-64 years observed in the Massachusetts Cancer Registry and Surveillance Epidemiology and End Results (SEER) registries for 2001-2013. We use difference-in-differences regression models to estimate changes in the likelihood of advanced stage diagnosis after Massachusetts health reform, relative to comparison states without expanded coverage (Connecticut, New Jersey, Georgia, Kentucky, and Michigan)., Results: We find some suggestive evidence of a decline in the proportion of advanced stage CRC cases. Approximately half of the CRC patients in Massachusetts and control states were diagnosed at advanced stages pre reform; there was a 2 percentage-point increase in this proportion across control states and slight decline in Massachusetts post reform. Adjusted difference-in-difference estimates suggest a 3.4 percentage-point (P=0.005) or 7% decline, relative to Massachusetts baseline, in the likelihood of advanced stage diagnosis after the reform in Massachusetts, though this result is sensitive to years included in the analysis. We did not find a significant effect of reform on BCA stage at diagnosis., Conclusions: The decline in the likelihood of advanced stage CRC diagnosis after Massachusetts health reform may suggest improvements in access to health care and CRC screening. Similar declines were not observed for BCA, perhaps due to established BCA-specific safety-net programs.

- Abstract
The American cancer survivor population is ever-growing, with necessary follow-up primarily accomplished in a high-touch fashion-adding to unsustainability and fragmentation of care. Given the complexities of the health care system processes needed to support survivorship, engineering approaches may best address performance deficits and facilitate the provision of patient-centered care. Such collaboration between health care and engineering is recommended for redesigning health care delivery systems. By using Systems Engineering Initiative for Patient Safety (SEIPS), a systems engineering model widely used to improve health care quality and delivery, the authors examine the work system to identify the barriers and facilitators to necessary care in the presence of a survivorship care plan and visit. Recommendations for future improvement include ensuring that care-planning processes are dynamic, clearly assigned, resilient, and integrated with electronic health record systems., (© 2018 American Cancer Society.)

- Abstract
Purpose of Review: The purpose of this review is to summarize the current literature on estrogen and progesterone antagonists and their effects on the cardiovascular system., Recent Findings: Estrogen and progesterone antagonists reduce cancer-related recurrence and mortality in women with ER-positive breast cancer. Recent studies, however, suggest that women with early stage breast cancer are more likely to die of cardiovascular disease than recurrent breast cancer. Estrogen antagonists have been shown to reduce endothelial function, to increase lipid profiles and to alter body composition accelerating atherosclerotic changes. While clinical trial data demonstrates mixed results of the impact of estrogen antagonists on cardiovascular risk, there is a growing body of evidence that estrogen suppression and estrogen antagonists result in biologic effects on the endothelium, altering lipid profiles and accelerating the risk of atherosclerosis. Further longitudinal work however is needed.

- Abstract
Purpose: Adjuvant endocrine therapy (AET) utilization is linked to improved clinical outcomes among breast cancer survivors (BCS); yet, AET adherence rates remain suboptimal. Little is known about provider perspectives regarding barriers and facilitators to AET-related symptom management (SM). In this study, we examined provider perspectives on the barriers and facilitators to AET-related SM among BCS and opportunities for improvement., Methods: We conducted three focus groups (FGs) with a multidisciplinary group of healthcare providers (n = 13) experienced in caring for BCS undergoing AET. We utilized semi-structured discussion guides to elicit provider perspectives on AET-related SM. FGs were audiotaped, transcribed, and analyzed using qualitative software to identify key themes., Results: Providers described patient-, provider-, and system-level barriers and facilitators to AET-related SM. At the patient-level, barriers included competing demands, limited time/resources, and possible misattribution of some symptoms to AET, while family/social relationships and insurance emerged as important facilitators. Discomfort with SM, limited time, and challenges distinguishing AET-related symptoms from other conditions were key provider-level barriers. Provider-level facilitators included routine symptom documentation and strong provider relationships. Care fragmentation and complexity of the cancer care delivery system were described as system-level barriers; however, survivor clinics were endorsed by providers., Conclusions: Provider perspectives on AET-related SM can shed light on SM barriers and facilitators spanning multiple levels of the cancer care delivery system. Strategies for improving AET-related SM in BCS include increasing patients' knowledge and engagement in SM, equipping providers with efficient SM strategies, and improving coordination of symptom-related services through survivorship programs.

- Abstract
Background: Cardiovascular disease (CVD) is the leading cause of morbidity and mortality among older postmenopausal women. The impact of postmenopausal breast cancer on CVD for older women is uncertain. We hypothesized that older postmenopausal women with breast cancer would be at a higher risk of CVD than similar aged women without breast cancer and that CVD would be a major contributor to the subsequent morbidity and mortality., Methods: In a prospective Women's Health Initiative study, incident CVD events and total and cause-specific death rates were compared between postmenopausal women with (n = 4,340) and without (n = 97,576) incident invasive breast cancer over 10 years post-diagnosis, stratified by 3 age groups (50-59, 60-69, and 70-79)., Results: Postmenopausal women, regardless of breast cancer diagnosis, had similar and high levels of CVD risk factors (e.g., smoking and hypertension) at baseline prior to breast cancer, which were strong predictors of CVD and total mortality over time. CVD affected mostly women age 70-79 with localized breast cancer (79% of breast cancer cases in 70-79 age group): only 17% died from breast cancer and CVD was the leading cause of death (22%) over the average 10 years follow up. Compared to age-matched women without breast cancer, women age 70-79 at diagnosis of localized breast cancer had a similar multivariate-adjusted hazard ratio (HR) of 1.01 (95% confidence interval [CI]: 0.76-1.33) for coronary heart disease, a lower risk of composite CVD (HR = 0.84, 95% CI: 0.70-1.00), and a higher risk of total mortality (HR = 1.20, 95% CI: 1.04-1.39)., Conclusion: CVD was a major contributor to mortality in women with localized breast cancer at age 70-79. Further studies are needed to evaluate both screening and treatment of localized breast cancer tailored to the specific health issues of older women.

- Abstract
Purpose/objectives: To assess the feasibility of auricular point acupressure to manage aromatase inhibitor-induced arthralgia. ., Design: Wait list control design. ., Setting: Outpatient clinics and oncology center. ., Sample: 20 women with aromatase inhibitor-induced arthralgia. ., Methods: After baseline data were collected, participants waited one month before they received acupressure once per week for four weeks at a convenient time. The baseline data served as the control comparison. Self-reported measures and blood samples were obtained at baseline, at preintervention, weekly during the intervention, and at post-intervention. ., Main Research Variables: The primary outcomes included pain intensity, pain interference, stiffness, and physical function. Inflammatory cytokines and chemokines were tested. ., Findings: After the four-week intervention, participants reported decreases in worst pain and pain interference, and improvements in physical function, cancer-related symptom severity, and interference. The proinflammatory cytokines and chemokines displayed a trend of a mean percentage reduction. The anti-inflammatory cytokine interleukin-13 increased from pre- to postintervention. ., Conclusions: Auricular point acupressure is feasible and may be effective in managing arthralgia in breast cancer survivors. ., Implications for Nursing: Nurses can administer acupressure in clinical settings, which could enhance the management of aromatase inhibitor-induced arthralgia and contribute to a shift from traditional disease-based biomedical models to a broader, integrative, medical paradigm for managing aromatase inhibitor-induced arthralgia.

- Abstract
A significant proportion of cancer patients and survivors are age 65 and over. Older adults with cancer often have more complex medical and social needs than their younger counterparts. Geriatric medicine providers (GMPs) such as geriatricians, geriatric-trained advanced practice providers, and geriatric certified registered nurses have expertise in caring for older adults, managing complex medical situations, and optimizing function and independence for this population. GMPs are not routinely incorporated into cancer care for older adults; however, their particular skill set may add benefit at many points along the cancer care continuum. In this article, we review the role of geriatric assessment in the care of older cancer patients, highlight specific case scenarios in which GMPs may offer additional understanding and insight in the care of older adults with cancer, and discuss specific mechanisms for incorporating GMPs into oncology care.

- Abstract
Unlabelled: This study provides preliminary evidence that risedronate not only preserves BMD but may also attenuate the loss of bone microarchitecture over 2years during a time of accelerated bone loss in post-menopausal breast cancer survivors on aromatase inhibitors., Introduction: Accelerated bone loss and elevated fracture risk are associated with the use of aromatase inhibitors (AIs) in women with breast cancer. We previously reported that the oral bisphosphonate, risedronate, can maintain bone mineral density (BMD) in the hip and spine over 2-years in post-menopausal breast cancer survivors on AIs. In this study, we examined whether oral bisphosphonates can also preserve bone microarchitecture as measured by the trabecular bone score (TBS) in this population., Methods: This 2-year randomized, double-blind, placebo-controlled trial included postmenopausal women over age 55 with breast cancer on an AI who had low bone mass. Participants provided informed consent and were randomized to risedronate 35mg once weekly or placebo. We examined 12- and 24-month changes in spine TBS, analyzed using linear mixed models., Results: One-hundred and nine women with a mean age of 70.5years were included in the analysis. In the placebo group, BMD declined at the spine and hip over the 24-month period but was preserved in the active treatment group (data previously reported). TBS declined in the placebo group by -2.1% and -2.3% at 12- and 24-months, respectively (p<0.005). The TBS percent change in bisphosphonate-treated patients was -0.9% and -1.3% at 12 and 24-months but did not reach statistical significance (p=0.24 and 0.14). The 12- and 24-month between-group differences were 0.9 (p=0.38) and 0.8 (p=0.44) percentage points. TBS change correlated with spine BMD changes in the placebo group at 12- and 24-months (r=0.33 and 0.34, p<0.01) but not in the active treatment group., Conclusion: The oral bisphosphonate risedronate preserves BMD and may attenuate loss of bone microarchitecture over 2years during a time of accelerated bone loss in breast cancer survivors on AIs, but more definitive evidence is needed., (Copyright © 2016 Elsevier Inc.

- Abstract
Supportive care is an essential component of anticancer treatment regardless of age or treatment intent. As the number of older adults with cancer increases, and supportive care strategies enable more patients to undergo treatment, greater numbers of older patients will become cancer survivors. These patients may have lingering adverse effects from treatment and will need continued supportive care interventions. Older adults with cancer benefit from geriatric assessment (GA)-guided supportive care interventions. This can occur at any stage across the cancer treatment continuum. As a GA commonly uncovers issues potentially unrelated to anticancer treatment, it could be argued that the assessment is essentially a supportive care strategy. Key aspects of a GA include identification of comorbidities, assessing for polypharmacy, screening for cognitive impairment and delirium, assessing functional status, and screening for psychosocial issues. Treatment-related issues of particular importance in older adults include recognition of increased bone marrow toxicity, management of nausea and vomiting, identification of anemia, and prevention of neurotoxicity. The role of physical therapy and cancer rehabilitation as a supportive care strategy in older adults is important regardless of treatment stage or intent.

- Abstract
Medication adherence to oral cancer therapy is a critical component to achieving optimal patient outcomes. As the US population ages, growing numbers of patients will be prescribed oral cancer therapy regimens, highlighting the need for innovative and scalable solutions. Clinical pharmacists offer tremendous promise to help patients improve their adherence to oral cancer therapy. Moreover, addition of oral chemotherapy to Centers for Medicare & Medicaid Services (CMS) medication adherence quality measures has the potential to improve care and result in better therapeutic outcomes with fewer costs for patients and payers. Future research is needed to test the use of pharmacist-managed interventions to improve adherence to oral cancer therapy., (© The Author(s) 2014.)

- Abstract
Unlabelled: In postmenopausal women with low bone mass and hormone-receptor-positive breast cancer on an aromatase inhibitor, risedronate maintained skeletal health assessed by bone density and turnover markers. Women with the greatest decreases in bone turnover markers at 12 months had the greatest increases in bone density at 24 months., Introduction: Aromatase inhibitors (AIs), adjuvant endocrine therapy for postmenopausal women with hormone-receptor-positive breast cancer, are associated with bone loss and fractures. Our objectives were to determine if (1) oral bisphosphonate therapy can prevent bone loss in women on an AI and (2) early changes in bone turnover markers (BTM) can predict later changes in bone mineral density (BMD)., Methods: We conducted a 2-year double-blind, placebo-controlled, randomized trial in 109 postmenopausal women with low bone mass on an AI (anastrozole, letrozole, or exemestane) for hormone-receptor-positive breast cancer. Participants were randomized to once weekly risedronate 35 mg or placebo, and all received calcium plus vitamin D. The main outcome measures included BMD, BTM [carboxy-terminal collagen crosslinks (CTX) and N-terminal propeptide of type 1 procollagen (P1NP)], and safety., Results: Eighty-seven percent completed 24 months. BMD increased more in the active treatment group compared to placebo with an adjusted difference at 24 months of 3.9 ± 0.7 percentage points at the spine and 3.2 ± 0.5 percentage points at the hip (both p < 0.05). The adjusted difference between the active treatment and placebo groups were 0.09 ± 0.04 nmol/LBCE for CTX and 23.3 ± 4.8 μg/mL for P1NP (both p < 0.05). Women with greater 12-month decreases in CTX and P1NP in the active treatment group had a greater 24-month increase in spinal BMD (p < 0.05). The oral therapy was safe and well tolerated., Conclusion: In postmenopausal women with low bone mass and breast cancer on an AI, the oral bisphosphonate risedronate maintained skeletal health.

Purpose/objectives: To conduct an investigation of women's experiences related to adjuvant endocrine therapy (AET) and managing AET-related symptoms., Research Approach: Qualitative, focus group design., Setting: Main campus of the University of Pittsburgh in Pennsylvania., Participants: 14 breast cancer survivors, aged 50 years or older, with AET-related symptoms., Methodologic Approach: Semistructured discussion guides were used to elicit recollections of conversations with healthcare providers about starting AET, symptom experiences, symptom management, and suggestions for improving management. Audiotaped discussions were transcribed and analyzed to identify themes., Findings: Women reported that, initially, AET was not viewed as a choice, but rather as the necessary next step to save their lives. After starting AET, women experienced difficulties making sense of, communicating about, and managing unanticipated AET-related symptoms. Women who experienced persistently bothersome symptoms began weighing the pros and cons of AET to decide whether to continue treatment., Conclusions: Focus group findings suggest multiple opportunities to better prepare patients for AET and to improve assessment and management of AET-related symptoms., Interpretation: By exploring AET-related symptom experiences, nurses may be able to promote AET adherence in breast cancer survivors.

- Abstract
Background: Breast cancer survivors often receive long-term adjuvant endocrine therapy (AET) to reduce recurrence risk. Adherence to AET is suboptimal, which may be due to the experience of symptoms and/or concerns. Few studies have comprehensively assessed self-reported concerns between those who currently, previously or have never received AET. The study objective is to describe self-reported physical and emotional concerns of breast cancer survivors who are current, prior, or never-recipients of AET., Methods: Secondary analysis was performed on a subset of survey data collected in the 2010 LIVESTRONG Survey. Breast cancer survivors (n = 1,013, mean 5.4 years post-diagnosis) reported on 14 physical and eight emotional concerns that began after diagnosis and were experienced within 6 months of participation in the survey. Bivariate analyses examined the prevalence of each concern by AET status. The relationships between AET and burden of physical or emotional concerns were modeled with logistic regression., Results: More than 50% of the participants reported currently experiencing cognitive issues, fatigue, fear of recurrence, emotional distress, and identity/grief issues. Thyroid dysfunction and stigma concerns were more common among participants with prior AET (p < 0.01), while fear of recurrence, emotional distress, and concern about appearance were more common among those currently receiving AET (p < 0.01). Fatigue, sexual dysfunction, and pain were more common among prior and current AET recipients (p < 0.01). In adjusted models, receipt of AET was associated with a higher number of physical, but not emotional concerns. A higher number of concerns was associated with younger age, having children, receipt of chemotherapy, longer duration of cancer treatment, and shorter time since diagnosis (p < 0.01)., Conclusions: Breast cancer survivors who received AET were at risk of developing a variety of physical and emotional concerns, many of which persisted after treatment. These findings suggest the importance of developing individualized, supportive resources for breast cancer survivors.

- Abstract
Unlabelled: There is a need to better understand the posttreatment concerns of the nearly 14 million survivors of cancer alive in the United States today and their receipt of care. Using data from 2,910 posttreatment survivors of cancer from the 2006 or 2010 LIVESTRONG Surveys, the authors examined physical, emotional, and practical concerns, receipt of care, and trends in these outcomes at the population level., Results: 89% of respondents reported at least one physical concern (67% received associated posttreatment care), 90% reported at least one emotional concern (47% received care), and 45% reported at least one practical concern (36% received care). Female survivors, younger survivors, those who received more intensive treatment, and survivors without health insurance often reported a higher burden of posttreatment concerns though were less likely to have received posttreatment care. These results reinforce the importance of posttreatment survivorship and underscore the need for continued progress in meeting the needs of this population. Efforts to increase the availability of survivorship care are extremely important to improve the chances of people affected by cancer living as well as possible in the posttreatment period.

- Abstract
Aromatase inhibitors (AIs) have become the standard adjuvant therapy of postmenopausal breast cancer survivors. AIs induce a reduction of bioavailable estrogens by inhibiting aromatase, which would be expected to induce alterations in body composition, more extensive than induced by menopause. The objectives are to examine the impact of AIs on (1) DXA-scan derived body composition and (2) gonadal hormone levels. This is a sub-analysis of a 2-year double-blind, placebo-controlled, randomized trial of 82 women with nonmetastatic breast cancer, newly menopausal following chemotherapy, who were randomized to risedronate (35 mg once weekly) versus placebo, and stratified for their usage of AI versus no AI. Outcomes included DXA-scan derived body composition and gonadal hormone levels. As a group, total body mass increased in women over 24 months. Women on AIs gained a significant amount of lean body mass compared to baseline as well as to no-AI users (P < 0.05). Women not on an AI gained total body fat compared to baseline and AI users (P < 0.05). Free testosterone significantly increased and sex hormone binding globulin (SHBG) significantly decreased in women on AIs compared to no AIs at 24 months (P < 0.01) while total estradiol and testosterone levels remained stable. Independent of AI usage, chemotherapy-induced postmenopausal breast cancer patients demonstrated an increase of total body mass. AI users demonstrated maintenance of total body fat, an increase in lean body mass and free testosterone levels, and a decrease in SHBG levels compared to no-AI users. The mechanisms and implications of these changes need to be studied further.

- Abstract
Introduction: Osteoporosis is a major health problem for postmenopausal women. Adjuvant hormonal therapy with aromatase inhibitors (AIs) in postmenopausal breast cancer patients further worsens bone loss. Bisphosphonates are able to prevent AI-induced bone loss, but limited data exists on their effect on bone structure. Our objectives were to (1) examine the impact of AIs and no-AIs on hip structural geometry (HSA) of chemotherapy-induced postmenopausal women, and (2) determine if oral bisphosphonates could affect these changes., Methods: This is a sub-analysis of a 2-year double-blind randomized trial of 67 women with nonmetastatic breast cancer, newly postmenopausal following chemotherapy (up to 8 years), who were randomized to risedronate, 35 mg once weekly (RIS) and placebo (PBO). Many women changed their cancer therapy from a no-AI to an AI during the trial. Outcomes were changes in Beck's HSA-derived BMD and structural parameters., Results: Eighteen women did not receive adjuvant hormone therapy, while 41 women received other therapy and 8 received AIs at baseline distributed similarly between RIS and PBO. Women on AIs and PBO were found to have the lowest BMD and indices. RIS improved BMD and several HSA indices at the intertrochanteric site in women regardless of their hormonal therapy, but most improvement was observed in women who were not on AIs (all p< or =0.05 except buckling ratio). Changes at the narrow neck and femoral shaft were similar., Conclusion: The use of AIs appears to lead to lower HSA-derived BMD and hip structural indices as compared to women on no or non-AI therapy in chemotherapy-induced postmenopausal breast cancer patients. Preventive therapy with once weekly oral risedronate maintains structural, skeletal integrity independently of the use of or type of adjuvant therapy.

- Abstract
The incidences of osteoporosis and cancer increase with age, and these two diagnoses are often made in the same individual. Both increasing age and hypogonadism associated with aging, as well as cancer therapies, can lead to loss of bone mass and increased risk for fragility fractures. Advancing age carries an association with increased incidence of cancers. Thus, cancer and its therapies may predispose an individual to osteoporosis and its associated morbidity and mortality. Prevention of bone loss and its consequent fractures is critical in the care of aging patients. This article reviews the mechanisms of bone metabolism and the principles of management of bone health in the older population with a history of cancer.

- Abstract
Background: Little is known about the long-term impact of androgen deprivation therapy (ADT) on body composition in men with prostate cancer. We compared body composition parameters in men with non-metastatic prostate cancer on or not on therapy with healthy, age-matched controls at baseline and monitored changes over a 2-year period., Methods: We measured body fat mass and lean body mass in 81 men with prostate cancer on no ADT, 43 men on acute ADT (less than 6 months), 67 men on chronic ADT (more than 6 months) and 53 age-matched healthy controls. Measurements were performed every 6 months for 2 years., Results: Men with prostate cancer on acute ADT (mean 3 months) had significant gains in body fat mass [1499.56+/-322.28g (mean+/-S.E.) after 12 months, 2167.15+/-676.45g after 24 months, p<0.01 for both] and losses in lean body mass (929.74+/-296.36g after 12 months, 1785.81+/-501.31g after 24 months, p<0.01 for both) over 2 years. Men on chronic ADT (mean 31 months) had smaller but still significant body composition changes over 24 months. Changes in body composition in men on no ADT were small and healthy controls had no significant changes., Conclusions: Men with prostate cancer on ADT have significant gains in body fat mass and losses lean body mass over 2 years. These changes are most pronounced with initiation of ADT.

- Abstract
Introduction: Chemotherapy-induced menopause is associated with bone loss. The effect on structural geometry is unknown. Our objective was to determine if oral bisphosphonate therapy could maintain or improve femoral geometry in breast cancer patients with chemotherapy-induced menopause., Methods: This preplanned 1 year interim, secondary analysis of the Risedronate's Effect on Bone loss in Breast CAncer Study (REBBeCA Study) examined hip structure analysis (HSA), i.e. changes in the bone cross-sectional area (bone CSA), section modulus (SM: measure of bending strength), cortical thickness (CT) and buckling ratio (BR: index of cortical bone stability), in a double-blind trial of 87 newly postmenopausal, nonmetastatic breast cancer patients, randomized to risedronate, 35 mg once weekly (RIS) versus placebo (PBO)., Results: After 12 months, intertrochanteric parameters demonstrated percentage improvement (RIS vs. PBO) from baseline in bone CSA (mean+/-SD: 4.25+/-6.29 vs. 0.60+/-5.99%), SM (3.97+/-6.40 vs. 0.80+/-7.08%), and CT [5.20+/-6.98 vs. 1.13+/-6.87% (all p-values <0.05 except SM p=0,0643)]. Similar improvements were observed at the femoral shaft [bone CSA: 2.24+/-5.74 vs. -0.78+/-5.73%; SM: 1.62+/-6.23 vs. -1.39+/-7.06%; CT: 3.79+/-7.84 vs. -0.17+/-7.90% (all p-values <0.05, RIS vs. PBO, except SM p= p =0.0568)]. At both sites, the BR had significant decreases consistent with improved strength., Conclusion: We conclude that RIS improves measures of hip structural geometry in women with breast cancer following chemotherapy.

- Abstract
Objectives: To investigate the influence of androgen deprivation therapy (ADT) in men with nonmetastatic prostate cancer., Methods: We conducted a 2-year controlled, prospective study. Twenty-three men on 6 months or longer of ADT (chronic), 12 men on less than 6 months of ADT (acute), and 13 men not on ADT (healthy controls or prostate cancer patients not on ADT) were studied. We used validated, objective tests for physical and visual-motor function and dual X-ray absorptiometry for body composition at baseline and at 24 months., Results: We found the baseline percentage of body fat increased and baseline percentage of lean mass decreased with duration of ADT (P <0.002 across groups for both). After 24 months, men on chronic ADT had significant declines in lean body mass percentage (P = 0.058) and increases in body fat percentage (P = 0.029). Men on acute ADT had smaller but still significant differences in body composition at baseline and similar trends at 24 months. At baseline, men on chronic ADT had longer chair rise times than men on no ADT (P = 0.073) or acute ADT (P = 0.035). Four-meter walk velocities at 24 months were slower in men on acute (P = 0.006) and chronic ADT (P <0.001)., Conclusions: Declines in lean body mass and increases in body fat percentage over 2 years are observed in men on ADT. Lower body physical function performance is reduced in men on chronic ADT. Changes in body composition and physical function should be considered in men on long-term ADT.

- Abstract
Sex differences in susceptibility to alcohol-induced liver injury have been observed in both humans and experimental animal models. Using a standard model of alcohol-induced fatty liver injury and microarray analysis, we have identified differential expression of hepatic genes in both sexes. The genes that exhibit differential expression are of three types: those that are changed only in male rats fed alcohol, those that change in only female rats fed alcohol, and those that change in both sexes, although not always in the same manner. Certain of the differentially expressed genes have previously been identified as participants in the induction of alcohol-induced liver injury. However, this analysis has identified a number of genes that heretofore have not been implicated in alcoholic liver injury; such genes may provide new areas of investigation into the pathogenesis of this disease.

- Abstract
Impaired nitric oxide (NO) activity in proatherosclerotic states has been suggested to be caused mainly by increased degradation of NO by oxygen radicals. In recent years, endothelial NO synthase has been identified as a system that contributes to oxygen radical stress under pathophysiologic conditions. We discuss the origin of NO synthase-derived superoxide production, as well as possibilities to modulate (pathologic) shifts in NO/superoxide production by endothelial NO synthase.
