Vulnerable elders survey and socioeconomic status predict functional decline and death among older women with newly diagnosed nonmetastatic breast cancer

Predictors and effects of toxicity experienced by older adults with cancer receiving systemic therapy in a randomized clinical trial of geriatric assessment

INTRODUCTION

Older adults represent a large segment of the oncology population, however, they remain underrepresented in clinical research. Treatment of older adults is often extrapolated using data from younger and fitter patients, which may not be appropriate. Furthermore the implications of toxicity from treatment can be greater for this population. Predicting toxicity from treatment and its effect on quality of life and functional status for older adults therefore is important.

MATERIALS AND METHODS

We analyzed data from a clinical trial of geriatric assessment and management for Canadian elders with cancer (5C study). We assessed whether the baseline Cancer and Aging Research Group (CARG) toxicity score, G8 score, and Eastern Cooperative Oncology Group (ECOG) performance predicted grade 3-5 toxicity using logistic regression and pattern mixture models. We also assessed the impact of toxicity on quality of life and functional decline. Patients were followed for six months.

RESULTS

Three hundred sixteen patients were included. Mean age was 76 years old and 40% of patients were female. One hundred nineteen patients (38%) experienced at least one grade 3-5 toxicity. Neither the CARG toxicity score, G8, or ECOG were predictive of grade 3-5 toxicity. Patients who experienced grade 3-5 toxicity were more likely to have functional impairments over time (odds ratio 3.71, p = 0.03). However, they maintained their quality of life.

DISCUSSION

In this secondary analysis of a randomized controlled trial of geriatric assessment and management we did not find any predictors of grade 3-5 toxicity. Patients who did experience toxicity were more likely to report functional decline over time. Older adults who do experience treatment related toxicity may benefit from increased supports.

Patient-reported geriatric assessment-based frailty index among older adults with gastrointestinal malignancies

BACKGROUND

Older adults with cancer are at increased risk of treatment-related toxicities and excess mortality. We evaluated whether a patient-reported geriatric assessment (GA) based frailty index can identify those at risk of adverse outcomes.

METHODS

Older adults (≥60 years) enrolled in a single-institutional prospective registry underwent patient-reported GA at initial evaluation in our medical oncology clinic. Using deficit accumulation method, we constructed a 44-item frailty index (CARE-FI), categorizing patients as robust, pre-frail, and frail. The primary outcome was overall survival (OS). Secondary outcomes included (a) functional decline at 3 months post-therapy (b) incident grade ≥3 treatment-related toxicities at six-month post-treatment. We used multivariate Cox and logistic regression models respectively to study the impact of frailty on primary and secondary outcomes.

RESULTS

We identified 589 older adults with a median age of 69 years; 55% males and 73% Whites. Overall, 168 (29%) were pre-frail and 230 (39%) frail. Being frail (vs. robust) was associated with worse OS (Hazards Ratio, HR 1.83, 95% Confidence Interval, CI 1.34-2.49, p < 0.001) after adjusting for age, sex, race/ethnicity, cancer type, cancer stage, and line of therapy. Similarly, frailty was associated with increased risk of functional decline (OR 3.01; 95% CI 1.33-6.81; p = 0.008) and grade ≥3 non-hematologic toxicities (OR 3.65; 95% CI 1.54-8.69; p = 0.003) but not hematologic toxicities (OR 1.01; 95% CI 0.46-2.22; p = 0.97).

CONCLUSIONS

Our frailty index using a patient-reported GA is a robust predictor of survival, functional decline, and treatment related toxicity among older adults with GI malignancies.

A randomized controlled trial of the effect of supervised exercise on functional outcomes in older African American and non-Hispanic White breast cancer survivors: Are there racial differences in the effects of exercise on functional outcomes?

BACKGROUND

The objective of this study was to test the hypothesis that exercise would be more effective than a support group plus Fitbit (SG+Fitbit) program in improving functional outcomes in older breast cancer survivors (BCSs) and that race would moderate the exercise effect on outcomes.

METHODS

Older African American (AA) and non-Hispanic White (NHW) BCSs were purposively recruited and enrolled into the 52-week randomized controlled trial. The interventions included 20 weeks of supervised moderate-intensity aerobic and resistance training followed by 32 weeks of unsupervised exercise called IMPROVE (n = 108) and a 20-week SG+Fitbit program followed by 32 weeks of unsupervised activity (n = 105). Study outcomes were assessed at 20 and 52 weeks. The primary outcome was the change in Short Physical Performance Battery (SPPB) scores 20 weeks from the baseline between arms. Secondary outcomes included change in the 6-Minute Walk Test (6MWT) in meters 20 weeks from the baseline between arms. General linear regression and multivariable logistic regression analyses were used.

RESULTS

The mean age was 71.9 years (SD, 5.9 years), and 44% were AA. SPPB scores did not differ between arms (adjusted difference in mean change, 0.13; 95% CI, -0.28 to 0.55; P = .53). However, the exercise arm (vs the SG+Fitbit arm) improved on the 6MWT (21.6 m; 95% CI, 2.5-40.6 m; P = .03). Race moderated the exercise effect on the 6MWT (adjusted interaction effect, 43.3 m; 95% CI, 6.3-80.2 m; P = .02); this implied that the change in the adjusted mean for the 6MWT at 20 weeks from the baseline was 43.3 m higher in AA exercise participants versus NHW exercise participants.

CONCLUSIONS

Combined aerobic and resistance exercise appears to improve physical performance in older BCSs, and the exercise effect might be moderated by race, with AAs appearing to derive larger benefits in comparison with NHWs. Larger studies are warranted to confirm the study findings.

Breast Cancer in Women Over 65 years- a Review of Screening and Treatment Options

Breast cancer is becoming increasingly prevalent in the women greater than 65 years of age. Most tumors are hormone receptor-positive in this group. Breast cancer screening recommendations for older women should be tailored based on life expectancy. Early stage breast cancer should be treated with conservative surgery followed by adjuvant endocrine therapy in HR+ patients. Primary endocrine therapy is a low-risk option for those with limited life expectancy. Adjuvant radiation therapy can be avoided in early stage, low-risk cancers. Evaluation should include comprehensive geriatric assessment. Treatment with less cytotoxic chemotherapy, HER-2 targeted therapies, and other biomarker-driven, molecularly targeted therapies should be sought whenever possible.

IMPROVE, a community-based exercise intervention versus support group to improve functional and health outcomes among older African American and Non-Hispanic White breast cancer survivors from diverse socioeconomic backgrounds: Recruitment strategies and baseline characteristics

BACKGROUND

Behavioral intervention studies in older breast cancer survivors, particularly older African American (AA) and socioeconomic status-disadvantaged breast cancer survivors, are lacking. To inform future studies, the authors examined recruitment strategies in older breast cancer survivors who participated in an exercise intervention study.

METHODS

IMPROVE is a randomized trial designed to evaluate a group-based exercise intervention versus a support group (ClinicalTrials.gov identifier, NCT02763228). Participants were aged ≥65 years who had survived stage I through III breast cancer and were within 5 years of treatment completion. Participants were recruited through multiple approaches, including peripheral, linguistic, and constituent-involving strategies that incorporated the identification of potentially eligible patients from 3 local hospitals and from State of Ohio registries and through direct clinician and community organization referrals.

RESULTS

Between October 2016 and November 2019, 7487 patients were screened, 4790 were potentially eligible, and 213 were randomized into the study. The eligible:randomization rates were 4.4% overall and 84%, 8%, and 2% for recruitment using direct referrals, hospital registries, and state registries, respectively. The median age of the randomized cohort was 70 years (range, 65-88 years) and included 44% AA and 44% socioeconomic status-disadvantaged breast cancer survivors. Compared with all registry-eligible patients, directly referred-eligible patients were more likely to be AA versus Non-Hispanic White (41% vs 19%; P = .006), to be contacted successfully (100% vs 33%; P < .0001), and to accept study participation (88% vs 16%; P < .0001).

CONCLUSIONS

Direct referrals appeared to be the most efficient strategy for recruiting AA survivors. Behavioral intervention studies seeking to target older AA and socioeconomic status-disadvantaged breast cancer survivors should include strategies that foster direct referrals to study participation.

The Frailty Syndrome: A Critical Issue in Geriatric Oncology

The number of older adults with cancer is growing in the United States, and there is a relative paucity of data relating the presence of frailty with its outcomes of interest. The authors present the surgical oncology, radiation oncology, and medical oncology literature with respect to the presence of frailty in older adults with cancer. More research is needed to understand how the presence of frailty should be used by surgical, radiation, and medical oncologists to guide patient counseling and treatment planning.

Frailty screening for predicting rapid functional decline, rapid progressive disease, and shorter overall survival in older patients with gastrointestinal cancer receiving palliative chemotherapy - a prospective, clinical study

OBJECTIVES

A growing number of older patients with cancer require well-founded clinical decision-making. Frailty screening is suggested as a service to improve outcomes in vulnerable older patients with cancer. This prospective study examined the value of frailty screening to predict rapid functional decline, rapid progressive disease (PD) and shorter overall survival (OS) in older patients with gastrointestinal cancer receiving palliative chemotherapy.

MATERIALS AND METHODS

Patients aged ≥70 years were screened for frailty in an oncologic department after clinical decision but before starting palliative chemotherapy. Screening was repeated at first response evaluation after approximately two months of chemotherapy. Frailty screening tools included performance status (PS), Charlson Comorbidity Index, G-8 using two different cut-offs (G8₁₄,G8₁₁), VES-13, Timed-Up-and-Go, Handgrip strength and falls.

RESULTS

A total of 170 patients were included, median age was 75.5 (70-88) years and 65.9% were male. The frequency of frailty varied from 14% to 74% according to the chosen frailty tool. In multivariate analysis G8₁₄ predicted OS (HR 1.5; 95%CI 1.0-2.4), whereas G8₁₁ predicted PD (OR 2.4; 1.1-5.6) and OS (HR 2.1; 1.4-2.9). VES-13 predicted functional decline (OR 3.5; 1.0-11.6), PD (OR 3.5; 1.5-8.4) and OS (HR 1.7; 1.2-2.4). Timed-Up-and-Go predicted OS (HR 1.8; 1.1-2.7). Handgrip strength and falls predicted functional decline (OR 4.5; 1.1-19 and OR 6.1; 1.4-25.8, respectively). PS predicted PD (OR 6.2; 2.6-14.7) and OS (HR 2.2; 1.5-3.2).

CONCLUSION

VES-13 was useful for predicting all three endpoints of interest. Frailty tools covering domains of functioning and nutrition are suggested for older patients with advanced gastrointestinal cancer.

IMPROVE, a community-based exercise intervention versus support group to improve functional and health outcomes among older African American and non-Hispanic White breast cancer survivors from diverse socioeconomic backgrounds: Rationale, design and methods

BACKGROUND

African Americans (AA) and socioeconomic status (SES) disadvantaged older breast cancer survivors (BCS) are more likely to experience poor functional and health outcomes. However, few studies have evaluated the putative beneficial effects of exercise on these outcomes in older racial minority and SES-disadvantaged BCS.

METHODS

This is a mixed-methods study that includes a randomized-controlled trial, "IMPROVE", to evaluate a group-based exercise intervention compared to a support group program in older BCS, followed by post-intervention semi-structured interviews to evaluate the intervention. The trial aims to recruit 220 BCS with 55 in each of four strata defined by race (AA versus Non-Hispanic Whites) and SES (disadvantaged vs. non-disadvantaged). Participants are ≥65 years old and within five years of treatment completion for stage I-III breast cancer. Participants are randomized to a 52-week, three sessions/week, one-hour/session, moderate intensity aerobic and resistance group exercise intervention, (n = 110) or a 52-week, one hour/week, support group intervention [attention-control arm], (n = 110). The first 20 weeks of both programs are supervised and the last 32 weeks, unsupervised. The primary outcome is the change in Short Physical Performance Battery (SPPB) Scores at 20 weeks from baseline, between the two arms. Secondary outcomes include change in SPPB scores at 52 weeks, change in body composition and biomarkers, at 20 and 52 weeks from baseline, between arms.

DISCUSSION

Results of the trial may contribute to a better understanding of factors associated with recruitment, and acceptability, and will inform future exercise programs to optimally improve health outcomes for older BCS.

Validation of the French version of the Vulnerable Elders Survey-13 (VES-13)

Background

Identifying and assessing degree and type of frailty among older persons is a major challenge when targeting high risk populations to identify preventive interventions. The Vulnerable Elders Survey-(VES-13) is a simple instrument to identify frailty defined as risk for death, functional decline or institutionalization.

Objective

Translate VES-13 into French and validate it.

Methods

The French version of VES-13 was developed by forward-backward translation of the VES-13 survey instrument. The authors assessed its feasibility, construct validity, and ability to predict the combined outcomes of admission to institution or death at 18 months, in 135 persons over 70 years of age living in the community. Subjects were recruited from three settings: Group 1 – a health prevention center (n = 45); Group 2 – an ambulatory care geriatric clinic (n = 40); and Group 3 – an intermediate care hospital unit (n = 50). The combined outcomes data were recorded by telephone interview with participants or a proxy.

Results

Feasibility of the French version, named Echelle de Vulnérabilité des Ainés-13 or EVA-13, was excellent. The scale classified 5 (11%) persons as vulnerable (score of 3 or more) in Group 1, 23 (58%) in Group 2 and 45 (90%) in Group 3 (p < 0.001) with scores of 0.91 +/− 1.16, 4.27 +/− 3.17 and 6.90 +/− 3.17, respectively (p < 0.001). At follow-up, among the 60 non-vulnerable subjects, 58 (96%) were alive and living at home, whereas 46 (65%) of the 70 vulnerable subjects were alive and living at home (p < 0.001).

Conclusions

EVA-13 was determined to be valid and reliable.

VES-13 and WHOQOL-bref cutoff points to detect quality of life in older adults in primary health care

OBJECTIVE:

To determine Vulnerable Elders Survey (VES-13) and WHOQOL-bref cutoff points to detect poor quality of life (QoL) in older individuals.

METHODS:

This is a cross-sectional study, performed in all primary health care units in Samambaia, DF, Brazil. The data were collected from August 2016 to May 2017. The sample size of 466 older individuals treated in primary health care was obtained considering a 5% margin of error, 95% confidence level, 50% prevalence, and 20% possible losses, in a population of 13,259 older individuals. The subjects answered the VES-13 and WHOQOL-bref questionnaires. They were divided into 3 subgroups: poorQoL (older individuals with self-reported very poor or poor QoL AND very dissatisfied or dissatisfied with their health), goodQoL (very good or good QoL AND very satisfied or satisfied with Health) and indeterminateQoL (NOT belonging to poorQoL or goodQoL subgroups). A receiver-operating characteristic (ROC) curve was performed with poorQoL (case) versus goodQoL (control) to determine the cutoff score in VES-13 and WHOQOL-bref. A diagnostic test using these cutoffs was carried out in all older individuals (n = 466).

RESULTS:

The VES-13 and WHOQOL-bref cutoff points to detect poorQoL were ≥ 2 and < 60, respectively. The area under ROC curve of VES-13 and WHOQOL-bref was 0.741 (CI95% 0.659-0.823; p < 0.001) and 0.934 (CI95% 0.881-0.987; p < 0.001), respectively. In diagnostic tests, VES-13 showed 84% sensitivity and 98.2% negative predictive value, and WHOQOL-bref, 88% sensitivity and 99% negative predictive value.

CONCLUSIONS:

VES-13 score ≥ 2 and WHOQOL-bref score < 60 adequately detected poorQoL in patients treated in primary health care. Our data suggest that older individuals with these scores require special treatment such as geriatrics collaborative care to improve this scenario, considering QoL impact on mortality.

Determinants of functional decline in older adults experiencing cancer (the INCAPAC study)

BACKGROUND

Previous studies have reported on the higher risk of functional decline among older patients with cancer. However, few have focused on factors of functional decline in older persons with cancer and are mainly hospital-based and focus on consequences of cancer treatment. The aim of the study was to identify determinants of functional decline in older subjects with cancer in a population-based study.

METHODS

Using cancer registries, we identified older subjects (age ≥ 65 years) with cancer in three prospective cohort studies from Gironde, a French department. Functional status was measured using the Instrumental Activities of Daily Living (IADL) and the basic Activities of Daily Living (ADL) scales, and functional decline was measured between cancer pre- and post-diagnosis visits. Studied variables were demographic and socioeconomic (age at diagnosis, sex, living alone, education), cancer-related (stage at diagnosis, treatment received), smoking status, health-related (polypharmacy, depressive symptomatology), and geriatric-specific (cognitive impairment or dementia). Analyses were performed using logistic regression models.

RESULTS

Age (≥85 years), cognitive impairment or dementia, and advanced stage at diagnosis were associated with a higher risk of ADL limitations, whether considering death or not. Age (≥85 years), education and polypharmacy were associated with a higher risk of ADL and/or IADL limitations.

CONCLUSIONS

We identified factors that could impact on ADL and/or IADL limitations in older patients with cancer. The information on these determinants is useful in clinical settings to identify patients with cancer at high risk of functional decline.

Frailty identified by geriatric assessment is associated with poor functioning, high symptom burden and increased risk of physical decline in older cancer patients: Prospective observational study

BACKGROUND:

Maintaining quality of life including physical functioning is highly prioritized among older cancer patients. Geriatric assessment is a recommended approach to identify patients with increased vulnerability to stressors (frailty). How frailty affects quality of life and physical functioning in older cancer patients has scarcely been investigated.

AIM:

Focusing on physical functioning and global quality of life, we investigated whether frailty identified by a geriatric assessment was associated with higher risk of quality-of-life deterioration during cancer treatment and follow-up.

DESIGN:

Prospective, observational study. Patients were classified as frail or non-frail by a modified geriatric assessment. Quality of life was measured using the European Organization for Research and Treatment of Cancer Core Quality-of-Life Questionnaire at inclusion, 2, 4, 6 and 12 months.

SETTING:

Eight Norwegian outpatient cancer clinics.

PARTICIPANTS:

Patients ⩾70 years with solid tumours referred for palliative or curative systemic medical cancer treatment.

RESULTS:

Among 288 patients included, 140 (49%) were frail and 148 (51%) non-frail. Frail patients consistently reported poorer scores on all functioning and symptom scales. Independent of age, gender and major cancer-related factors, frail patients had significantly poorer physical functioning and global quality of life during follow-up, and opposed to non-frail patients they had both a clinically and statistically significant decline in physical functioning from baseline until 12 months.

CONCLUSIONS:

Geriatric assessment identifies frail patients with increased risk of physical decline, poor functioning and high symptom burden during and following cancer treatment. Frail patients should therefore receive early supportive or palliative care.

Characteristics Associated With Physical Function Trajectories in Older Adults With Cancer During Chemotherapy

CONTEXT

Studies on physical function trajectories in older adults during chemotherapy remain limited.

OBJECTIVES

The objective of this study was to determine demographic, clinical, and symptom characteristics associated with initial levels as well as trajectories of physical function over two cycles of chemotherapy in adults aged ≥65 years with breast, gastrointestinal, gynecological, or lung cancer.

METHODS

Older adults with cancer (n = 363) who had received chemotherapy within the preceding four weeks were assessed six times over two cycles of chemotherapy using the Short Form-12 Physical Component Summary (PCS) score. Hierarchical linear modeling was used to evaluate for interindividual variability in initial levels and trajectories of PCS scores.

RESULTS

Mean age was 71.4 years (SD 5.5). Mean PCS score at enrollment was 40.5 (SD .45). On average, PCS scores decreased slightly (i.e., 0.21 points) at each subsequent assessment. Lower PCS scores at enrollment were associated with older age, greater comorbidity, being unemployed, lack of regular exercise, higher morning fatigue, lower evening energy, occurrence of pain, lower trait anxiety, and lower attentional function. Only higher morning fatigue and lower enrollment PCS scores were associated with decrements in physical function over time.

CONCLUSION

While several symptoms were associated with decrements in PCS scores at enrollment in older adults with cancer receiving chemotherapy, morning fatigue was the only symptom associated with decreases in physical function over time. Regular assessments of symptoms and implementation of evidence-based interventions should be considered to maintain physical function in older adults during chemotherapy.

Practical Assessment and Management of Vulnerabilities in Older Patients Receiving Chemotherapy: ASCO Guideline for Geriatric Oncology

Purpose To provide guidance regarding the practical assessment and management of vulnerabilities in older patients undergoing chemotherapy. Methods An Expert Panel was convened to develop clinical practice guideline recommendations based on a systematic review of the medical literature. Results A total of 68 studies met eligibility criteria and form the evidentiary basis for the recommendations. Recommendations In patients ≥ 65 years receiving chemotherapy, geriatric assessment (GA) should be used to identify vulnerabilities that are not routinely captured in oncology assessments. Evidence supports, at a minimum, assessment of function, comorbidity, falls, depression, cognition, and nutrition. The Panel recommends instrumental activities of daily living to assess for function, a thorough history or validated tool to assess comorbidity, a single question for falls, the Geriatric Depression Scale to screen for depression, the Mini-Cog or the Blessed Orientation-Memory-Concentration test to screen for cognitive impairment, and an assessment of unintentional weight loss to evaluate nutrition. Either the CARG (Cancer and Aging Research Group) or CRASH (Chemotherapy Risk Assessment Scale for High-Age Patients) tools are recommended to obtain estimates of chemotherapy toxicity risk; the Geriatric-8 or Vulnerable Elders Survey-13 can help to predict mortality. Clinicians should use a validated tool listed at ePrognosis to estimate noncancer-based life expectancy ≥ 4 years. GA results should be applied to develop an integrated and individualized plan that informs cancer management and to identify nononcologic problems amenable to intervention. Collaborating with caregivers is essential to implementing GA-guided interventions. The Panel suggests that clinicians take into account GA results when recommending chemotherapy and that the information be provided to patients and caregivers to guide treatment decision making. Clinicians should implement targeted, GA-guided interventions to manage nononcologic problems. Additional information is available at www.asco.org/supportive-care-guidelines .

Functional trajectories before and after a new cancer diagnosis among community-dwelling older adults

BACKGROUND

To characterize functional trajectories in the year before and after a new cancer diagnosis among older adults and to identify risk factors for worsening disability post-diagnosis.

METHODS

We identified 170 participants 70+ years with monthly assessments of thirteen basic, instrumental, and mobility activities and with a new cancer diagnosis from 1998 to 2014. A group-based trajectory model identified distinct functional trajectories based on a total disability score during the twelve months pre- and post-diagnosis. We evaluated associations between potential risk factors at the time of cancer diagnosis and worsening disability post-diagnosis, explored functional transitions from pre- to post-diagnosis and identified participants whose functional trajectories worsened.

RESULTS

Three pre-diagnosis functional trajectories were identified among 170 participants (mean age at diagnosis: 83 years (range: 73-105 years): mild, moderate, and severe disability. Three post-diagnosis functional trajectories were identified among 158 non-decedents: mild, moderate, and severe disability. Most participants (93.9%) with severe disability pre-diagnosis had severe disability post-diagnosis. Risk factors independently associated with worsening disability post-diagnosis included moderate or severe disability pre-diagnosis (adjusted risk ratio, aRR: moderate: 2.96; 95%CI: 2.11-4.16; severe: 5.11; 95%CI: 3.07-8.52) vs. mild (reference), poor physical capability (aRR: 1.57; 95%CI: 1.07-2.30), and incurable stage (aRR:1.99; 95%CI: 1.41-2.80). 40% of participants with a mild or moderate disability trajectory pre-diagnosis transitioned to a worse functional trajectory post-diagnosis.

CONCLUSION

Older adults followed distinct functional trajectories in the twelve months before and after cancer diagnosis. Functional trajectory pre-diagnosis, poor physical capability, and incurable stage were independent risk factors for worsening disability post-diagnosis.

Factors Associated with Functional Decline in Elderly Female Breast Cancer Patients in Appalachia

Background

Functional status has been previously shown in the elderly cancer population to predict both mortality as well as treatment tolerance. The goal of this study was to determine if there are certain subsets of the elderly breast cancer population that are at higher risk of experiencing functional decline following treatment.

Methods

Patient charts from the Edwards Comprehensive Cancer Center in Huntington, West Virginia, from January 2006 – January 2016 were reviewed. Relevant inclusion criteria included patients of 65 years of age and older with a new diagnosis of Stage 0-III breast cancer. Functional decline was defined as an increase of at least one point in Eastern Cooperative Oncology Group (ECOG) scores within one year of diagnosis. ECOG performance status was subjectively determined by the physician. Fisher’s exact test and Pearson’s Chi-squared test were initially utilized to assess potential factors associated with functional decline such as pretreatment ECOG score, age at diagnosis, stage, hormone receptor status, type of surgery received, whether radiation therapy, chemotherapy, or hormonal therapy was received, medical comorbidities, body mass index (BMI), complaints of weakness at diagnosis, and ambulatory status. Factors that were found to be significant were further assessed via multivariate logistic regressions.

Results

Three-hundred and fourteen patients were identified as meeting inclusion criteria. At one-year follow-up, 45 patients (14.3% of the cohort) had documented functional decline. On initial analysis, factors associated with functional decline included Stage III disease (p=0.002) and complaints of weakness at diagnosis (p=0.004). Following multivariate analysis, Stage III disease (p = 0.02), complaints of weakness at diagnosis (p = 0.04), and bilateral mastectomy (p = 0.03) were significantly associated with functional decline.

Conclusion

Patients who were diagnosed with Stage III breast cancer, had complaints of weakness at time of diagnosis, or had bilateral mastectomies were more likely to have a decline in functional status at one-year follow-up. Awareness of factors associated with functional decline in the elderly Appalachian population with Stage 0-III breast cancer will be useful during discussions regarding patient expectations, treatment, and goals of care. Elderly breast cancer patients for whom bilateral prophylactic mastectomies are not indicated may be better served by lumpectomy alone (based on patient age, hormone receptor status, and tumor size), lumpectomy followed by radiation therapy, or unilateral mastectomy to maximize the likelihood of functional preservation following treatment.

Temporal order of cancers and mental disorders in an adult population

BACKGROUND

Population-based examination of comorbidity is an emerging field of study.

AIMS

The purpose of the present population level study is to expand our understanding of how cancer and mental illness are temporally associated.

METHOD

A sample of 83 648 056 physician billing records for 664 838 (56% female) unique individuals over the age of 18 was stratified on ages 19-49 years and 50+ years, with temporal order of mental disorder and cancer forming the basis of comparison.

RESULTS

Mental disorders preceded cancers for both genders within each age strata. The full range of cancers and mental disorders preceding or following each pivot ICD class are described in terms of frequency of diagnosis and duration in days, with specific examples illustrated.

CONCLUSIONS

The temporal comorbidity between specific cancers and mental disorders may be useful in screening or clinical planning and may represent indicators of disease mechanism that warrant further screening or investigation.

Black-white disparity in physical performance among older women with newly diagnosed non-metastatic breast cancer: Exploring the role of inflammation and physical activity

OBJECTIVE

To examine racial differences in physical performance among older women with newly diagnosed non-metastatic breast cancer and identify clinical, behavioral and biological factors that might contribute to such disparities.

METHODS

This is a cross-sectional study of women aged ≥65 years with newly diagnosed stage I-III breast cancer recruited from ambulatory oncology clinics at an academic center, between September 2010 and August 2015. Participants completed a Comprehensive Geriatric Assessment and laboratory testing for biomarkers of inflammation [interleukin-6 (IL6)] prior to receiving systemic treatment for cancer. The primary outcome was poor physical performance, defined as scoring ≤7 on the Short Physical Performance Battery, Yes or No. Logistic regression analyses were undertaken.

RESULTS

Among 135 women with mean age of 74.8 years (SD = 6.9), 31% were African-American (AA), and 33% had poor physical performance. Controlling for age, education, comorbidities and geriatric syndromes, participants with poor physical performance were more likely to be AA [versus (vs.) Non-Hispanic Whites (NHW)], odds ratio (OR) = 3.10, 95% confidence interval (CI) = 1.18-8.15. Controlling further for physical activity (PA) attenuated the racial disparity in physical performance (OR = 2.50, CI = 0.91-6.84). Lastly, controlling for IL6 further diminished the racial disparity in physical performance (OR = 1.93, CI = 0.67-5.56). In adjusted models, PA and IL6 explained 29% and 38%, respectively, of the racial disparity in poor physical performance.

CONCLUSION

Among older women with newly diagnosed non-metastatic breast cancer, poor physical performance was prevalent and AA were disproportionately affected. Less engagement in physical activity and subclinical inflammation partly contributed to this disparity.

What Every Oncologist Should Know About Geriatric Assessment for Older Patients With Cancer: Young International Society of Geriatric Oncology Position Paper

Aging is a heterogeneous process. Most newly diagnosed cancers occur in older adults, and it is important to understand a patient's underlying health status when making treatment decisions. A geriatric assessment provides a detailed evaluation of medical, psychosocial, and functional problems in older patients with cancer. Specifically, it can identify areas of vulnerability, predict survival and toxicity, assist in clinical treatment decisions, and guide interventions in routine oncology practice; however, the uptake is hampered by limitations in both time and resources, as well as by a lack of expert interpretation. In this review, we describe the utility of geriatric assessment by using an illustrative case and provide a practical approach to geriatric assessment in oncology.

Perspective of older African-American and Non-Hispanic white breast cancer survivors from diverse socioeconomic backgrounds toward physical activity: A qualitative study

BACKGROUND

We sought to explore the perspective of older breast cancer survivors (BCS) from diverse racial and socioeconomic backgrounds toward physical activity (PA) to inform the design of a PA program that fosters acceptability.

METHODS

Participants included sixty women, ≥65years, within two years of treatment completion for stage I-III breast cancer. We purposely sampled ≥ten patients in each race [African-American (AA) and Non-Hispanic White (NHW)] and socioeconomic status (SES) [SES disadvantaged and SES non-disadvantaged] group. Participants completed in-person interviews (n=60) and follow-up focus groups (n=45). Thematic analyses were employed.

RESULTS

The median age was 71.0years (range: 65-87years). Five themes emerged: 1) importance of PA; 2) current PA participants engaged in; 3) influence of race and culture on PA attitudes and beliefs; 4) barriers to PA and facilitators to PA; and 5) PA preferences. Barriers included health issues (43%), particularly cancer treatment side effects such as fatigue. Facilitators included religious faith (38%) and family (50%). Preferences included group exercise (97%) and strength training (80%) due to concerns participants had with diminished upper body strength after cancer treatment. Although AA (59%) and SES non-disadvantaged (78%) participants reported that race and culture influenced their attitudes toward PA, it did not translate to racial and SES differences in preferences.

CONCLUSION

Among older BCS, physical activity preferences were shaped by cancer experience, rather than by race and SES. Physical activity programs for older BCS should focus on addressing cancer treatment-related concerns and should include strength training to ensure PA programs are more acceptable to older BCS.

Short Physical Performance Battery, usual gait speed, grip strength and Vulnerable Elders Survey each predict functional decline among older women with breast cancer

OBJECTIVE

To determine the ability of three performance-based measures [Short Physical Performance Battery (SPPB), gait speed, and Grip Strength] and a self-report measure [Vulnerable Elders Survey (VES-13)] to predict functional decline among older women with breast cancer.

PATIENTS AND METHODS

Longitudinal data from a study of women ≥65years, with newly diagnosed stages I-III breast cancer, recruited from ambulatory oncology clinics between July 2010 and April 2014, was used. The primary outcome was functional decline, Yes or No, defined as a decrease in ≥1-point from baseline to 12months, on Activities of Daily Living Scales. Multivariable logistic regression and receiver operator curve analyses were conducted.

RESULTS

Among 123 participants 18 (15%) developed functional decline. The predictive abilities for measures were: SPPB [Adjusted odds ratio (AOR)=1.65 per unit decrease in scores, 95% confidence interval (CI)=1.33-2.05; area under the receiver operator curve (AUC)=0.93; sensitivity=94%, specificity=80%]; gait speed (AOR=1.76 per unit increase in usual walking time, CI=1.29-2.41; AUC=0.93; sensitivity=87%, specificity=79%); VES-13 (AOR=1.64 per unit increase in scores, CI=1.31-2.05; AUC=0.87; sensitivity=83%, specificity=84%); and grip strength: (AOR=1.18 per unit decrease in grip strength, CI=1.06-1.30; AUC=0.80; sensitivity=67%, specificity=77%).

CONCLUSION

SPPB, gait speed, grip strength and VES-13 all demonstrated excellent predictive abilities for functional decline. Larger studies are warranted to confirm the utility of these measures for identifying older adults with cancer at increased risk for functional decline, who may then be targeted for studies to explore the effects of interventions to improve function.
