Frailty and health-related quality of life in older women with breast cancer.

PURPOSE: In older women, breast cancer and its treatment can have profound impact on their physical, mental, and social health, especially in frail patients. This study evaluated the association between frailty and long-term health-related quality of life (HRQOL) in older women undergoing breast cancer treatment. METHODS: Using the Carolina Senior Registry (CSR), participants with breast cancer were contacted to complete a follow-up HRQOL questionnaire (median 4 years). Baseline Geriatric Assessment (GA) variables were used to calculate the Carolina Frailty Index (CFI) and categorize participants as robust, pre-frail, or frail. Outcomes included HRQOL domains of physical function, social roles, fatigue, depression, anxiety, pain, and sleep disturbance assessed using PROMIS® instruments. Regression modeling compared outcomes between frailty groups using adjusted mean differences (AMD). RESULTS: Of 190 eligible patients, 63 completed follow-up HRQOL survey. Mean age was 70 years (range 65-86) and 91% were white. Based on the CFI, 49 (78%) patients were robust, 11 (18%) pre-frail, and 3 (5%) frail. After controlling for age and cancer stage, patients identified as pre-frail/frail reported worse physical function (AMD - 9.2, p < 0.001) and social roles (AMD - 7.2, p = 0.002) and more fatigue (AMD 7.6, p = 0.008), depression (AMD 5.6, p = 0.004), and sleep disturbance (AMD 6.9, p = 0.008) compared to robust patients at follow-up. CONCLUSIONS: Frailty in older women with breast cancer was associated with worse long-term HRQOL outcomes. Further research is needed to develop interventions for frail patients at-risk for reduced HRQOL.

Recent advances in non-surgical management of cancer in the elderly.

This article summarizes the seminal publications from mid-2016 through 2017 in the area of medical care for older adults with cancer. Areas addressed include chemotherapy tolerance and efficacy in the aged, geriatric fitness assessments, and advancements in palliative and supportive care. The practice-changing finding from this past year's publications is that antipsychotics should not be used in the management of terminal delirium in older adults receiving palliative care. The other trials demonstrated an improved understanding of the utility of geriatric assessments in patients with cancer, developed the body of information about which chemotherapy agents are safe and effective in older adults (and which are not), and expanded our understanding of good palliative and supportive care.

Frailty and skeletal muscle in older adults with cancer.

OBJECTIVE: Computerized tomography (CT) imaging is routine in oncologic care and can be used to measure muscle quantity and composition that may improve prognostic assessment of older patients. This study examines the association of single-slice CT-assessed muscle measurements with a frailty index in older adults with cancer. MATERIALS AND METHODS: Using the Carolina Senior Registry, we identified patients with CT imaging within 60days ± of geriatric assessment (GA). A 36-item Carolina Frailty Index was calculated. Cross-sectional skeletal muscle area (SMA) and Skeletal Muscle Density (SMD) were analyzed from CT scan L3 lumbar segments. SMA and patient height (m2) were used to calculate skeletal muscle index (SMI). Skeletal Muscle Gauge (SMG) was calculated by multiplying SMI×SMD. RESULTS: Of the 162 patients, mean age 73, 53% were robust, 27% pre-frail, and 21% frail. Significant differences were found between robust and frail patients for SMD (29.4 vs 24.1 HU, p<0.001) and SMG (1188 vs 922AU, p=0.003), but not SMI (41.9 vs 39.5cm2/m2, p=0.29). After controlling for age and gender, for every 5 unit decrease in SMD, the prevalence ratio of frailty increased by 20% (PR=1.20 [1.09, 1.32]) while the prevalence of frailty did not differ based on SMI. CONCLUSIONS: Muscle mass (measured as SMI) was poorly associated with a GA-based frailty index. Muscle density, which reflects muscle lipid content, was more associated with frailty. Although frailty and loss of muscle mass are both age-related conditions that are predictive of adverse outcomes, our results suggest they are separate entities.

Patient-Reported Comorbidity and Survival in Older Adults with Cancer.

BACKGROUND: Our ability to optimize the care of older adults with cancer and comorbid illnesses is insufficient because most clinical trials lack systematic measurement. The primary purpose of this study was to evaluate the association between patient-reported comorbidity and all-cause mortality using various comorbidity scoring algorithms. MATERIALS AND METHODS: The Carolina Senior Registry was linked with the North Carolina Central Cancer Registry to obtain mortality data. Comorbidity was assessed using the patient-reported Older Americans Resources and Services Questionnaire subscale that assesses 13 specific conditions and the degree to which each impairs activities. Multivariable Cox proportional hazard regression models were used to evaluate the association between comorbidities and all-cause mortality. RESULTS: The study sample included 539 patients; the median age was 72 years, 72% were female, and 47% had breast cancer. Overall, 92% reported ≥1 comorbid condition, with a mean of 2.7 conditions (range 0-10), with arthritis and hypertension the most common (52% and 50%, respectively). Approximately 60% reported a functional limitation related to comorbidity. After adjusting for time from diagnosis to geriatric assessment, age, cancer type, and stage, the risk of death increased by 5% for each unit increase in comorbidity burden score (adjusted hazard ratio [HR] = 1.05, 95% confidence interval [CI]: 1.01-1.10) and 12% for each comorbid condition impacting function (HR = 1.12, 95% CI: 1.02-1.23). CONCLUSION: Comorbid conditions in older adults with cancer are highly prevalent and associated with all-cause mortality, particularly those conditions that impair function. Routine comorbidity assessment should be included in clinical trials and can be measured via a simple one-page patient-reported questionnaire. IMPLICATIONS FOR PRACTICE: In order to optimize and personalize the care of older adults with cancer, systematic measurement of comorbidities is necessary in both clinical trials and routine practice. Patient-reported comorbid conditions in older adults with cancer are highly prevalent and are associated with increased risk of all-cause mortality, particularly for those conditions that impair function. Comorbidity can be systematically measured via a one-page patient-reported questionnaire and should be incorporated into future clinical trials and considered for use in oncology clinics to aid in assessing older adults with cancer.

Frailty Index Developed From a Cancer-Specific Geriatric Assessment and the Association With Mortality Among Older Adults With Cancer.

Background: An objective measure is needed to identify frail older adults with cancer who are at increased risk for poor health outcomes. The primary objective of this study was to develop a frailty index from a cancer-specific geriatric assessment (GA) and evaluate its ability to predict all-cause mortality among older adults with cancer. Patients and Methods: Using a unique and novel data set that brings together GA data with cancer-specific and long-term mortality data, we developed the Carolina Frailty Index (CFI) from a cancer-specific GA based on the principles of deficit accumulation. CFI scores (range, 0-1) were categorized as robust (0-0.2), pre-frail (0.2-0.35), and frail (>0.35). The primary outcome for evaluating predictive validity was all-cause mortality. The Kaplan-Meier method and log-rank tests were used to compare survival between frailty groups, and Cox proportional hazards regression models were used to evaluate associations. Results: In our sample of 546 older adults with cancer, the median age was 72 years, 72% were women, 85% were white, and 47% had a breast cancer diagnosis. Overall, 58% of patients were robust, 24% were pre-frail, and 18% were frail. The estimated 5-year survival rate was 72% in robust patients, 58% in pre-frail patients, and 34% in frail patients (log-rank test, P<.0001). Frail patients had more than a 2-fold increased risk of all-cause mortality compared with robust patients (adjusted hazard ratio, 2.36; 95% CI, 1.51-3.68). Conclusions: The CFI was predictive of all-cause mortality in older adults with cancer, a finding that was independent of age, sex, cancer type and stage, and number of medical comorbidities. The CFI has the potential to become a tool that oncologists can use to objectively identify frailty in older adults with cancer.

Managing Cancer Pain in Older Adults.

Managing cancer pain in older adults can be complex and challenging. Understanding the unique needs of older patients with cancer is important to safe and effective pain management. The goals of this review are to discuss the assessment of older adults with cancer-related pain, treatment of cancer pain, and adverse effects or potential risks from treatment that are unique to older patients. A detailed pain assessment and when possible utilizing the geriatric assessment are vital to developing a cancer pain management plan. The geriatric assessment can help clinicians uncover problems not routinely assessed in the standard oncologic evaluation. Opioid pain medications are safe and effective for older adults with cancer pain as long as these medications are closely monitored and titrated slowly. In addition to the well-known adverse effects of opioid medications, clinicians need to be aware of the unique risks in older adults, which could include delirium, polypharmacy, and falls.

Data Linkage to Improve Geriatric Oncology Research: A Feasibility Study.

Older adults (aged 65 years and older) diagnosed with cancer account for most cancer-related morbidity and mortality in the United States but are often underrepresented on clinical trials. Recent attention from a variety of professional, research, regulatory, and patient advocacy groups has centered on data linkage and data sharing as a means to capture patient information and outcomes outside of clinical trials to accelerate progress in the fight against cancer. The development of a more robust observational research data infrastructure would help to address gaps in the evidence base regarding optimal approaches to treating cancer among the growing and complex population of older adults. To demonstrate the feasibility of building such a resource, we linked information from a sample of older adults with cancer in North Carolina using three distinct, but complementary, data sources: (a) the Carolina Senior Registry, (b) the North Carolina Central Cancer Registry, and (c) North Carolina fee-for-service Medicare claims data. A description of the linkage process, metrics, and characteristics of the final cohort is reported. This study highlights the potential for data linkage to improve the characterization of health status among older adults with cancer and the possibility to conduct passive follow-up for outcomes of interest over time. Extensions of these linkage efforts in partnership with other institutions will enhance our ability to generate evidence that can inform the management of older adults with cancer.

Frailty and inflammatory markers in older adults with cancer.

We examined the associations between frailty and inflammatory markers, in particular neutrophil lymphocyte ratio (NLR), in elderly cancer patients. We conducted cross-sectional analyses of data derived from the Carolina Seniors Registry (CSR), a database of geriatric assessments (GA) in older adults (≧65 years) with cancer. We included patients in the CSR who had a GA and complete blood count test before initiation of therapy. The primary outcome was frailty, determined using the 36-item Carolina Frailty Index (CFI). In our sample of 133 patients, the median age was 74, and 54% were robust, 22% were pre-frail, and 24% were frail. There was a significant positive correlation between CFI and NLR (r = 0.22, p = 0.025). In multivariable analysis, patients in the top tertile of NLR had an odds ratio of 3.8 (95% CI = 1.1-12.8) for frail/pre-frail status, adjusting for age, sex, race, education level, marital status, cancer type and stage. In bivariable analyses, higher NLR was associated with lower instrumental activity of daily living (IADL) score (p = 0.040) and prolonged timed up and go (p = 0.016). This study suggests an association between frailty and inflammation in older adults with cancer.

Survivorship care for older adults with cancer: U13 conference report.

Older adult cancer survivors currently account for almost 60% of all cancer survivors. The number of older cancer survivors will continue to increase as the population ages and as patients' live longer after a cancer diagnosis. As part of cancer center accreditation, the American College of Surgeons Commission on Cancer® (CoC) has placed great importance on survivorship care planning. While the CoC has set standards for general survivorship care, there is sparse evidence on how to best care for older adult cancer survivors. Concern exists among the medical community that survivorship care plans could increase paperwork without improving outcomes. Given the diverse and unique needs of older adult cancer survivors, the inter-professional team provides a structure and process for survivorship care built around the particular needs of older adults. The Cancer and Aging Research Group (CARG), in partnership with the NIA/NCI, held a U13 conference in May 2015 in part to discuss survivorship care for older adults with cancer. This report discusses four themes that emerged from one section of the conference: (1) survivorship care is a process that continually evolves to meet the needs of older adults; (2) older adult cancer survivors have unique needs and care plans should be tailored to meet these needs; (3) the inter-professional team is ideally suited to structure survivorship care of older adults; (4) patient advocacy must be encouraged throughout the cancer care continuum. As evidence based survivorship practices develop, the unique needs of older adults need to be given substantial attention.

Physical activity communication between oncology providers and patients with early-stage breast, colon, or prostate cancer.

BACKGROUND: National guidelines recommend that patients with a cancer diagnosis engage in regular physical activity to reduce cancer-related fatigue, maintain quality of life and physical function, and improve overall prognosis and survival. This study investigates oncology provider communications about physical activity during routine clinic visits with patients with early-stage breast, colon, or prostate cancer. METHODS: This study used a retrospective chart review for documentation of inquiries or recommendations pertaining to physical activity in clinician notes and after-visit patient summaries. RESULTS: In a 1-month period, 55 oncology providers had 361 encounters (clinic visits) with early-stage cancer patients. Thirty-five percent of these encounters included a provider communication about "physical activity," "exercise," or "activity." Encounters with a medical oncologist resulted in a physical activity communication 55% of the time, whereas encounters with other clinician specialties did so 20% of the time (P < .0001). The likelihood of a physical activity communication increased with patient age (P < .001). When the encounter was with a patient who was being seen for surveillance, chemotherapy, or endocrine treatment, the rate of physical activity communications was significantly higher (46%, 37%, and 58%, respectively) than the rate when the visit was during radiation treatment or surgery (6% and 19%, respectively; P < .0001). CONCLUSIONS: This study shows that it is feasible for oncology providers to have physical activity communications during routine clinic visits; however, the frequency of physical activity communications varies among providers. Interventions are needed to remind and encourage all oncology providers to encourage their patients with early-stage cancer to be physically active. .

Monoclonal Gammopathy of Undetermined Significance and Multiple Myeloma in Older Adults.

Multiple myeloma (MM) and monoclonal gammopathy of undetermined significance (MGUS) are plasma cell disorders of aging. The landscape of the diagnosis and management of MM and MGUS are rapidly changing. This article provides an updated understanding of the clinical presentation, evaluation, diagnosis, and management of older adults with MM and MGUS. Because most oncology providers are not formally trained in geriatric medicine, geriatricians play a key role in providing oncologists with a broader understanding of patient health status in the hope of improving outcomes for older adults with MM.

Falls in Older Adults With Cancer: Evaluation by Oncology Providers.

PURPOSE: Falls in older adults are common. Screening for falls is quick, simple, and important because falls increase the risk of morbidity and mortality in older patients with cancer. The aim of this study was to evaluate oncology providers' recognition of and response to falls in older patients with cancer. MATERIALS AND METHODS: From a sample of older patients with cancer who completed a geriatric assessment blinded to oncology providers, we identified patients who self-reported falls within the past 6 months. Their history and physical and/or clinic notes completed by an oncology provider were reviewed for the following: documentation of falls, gait assessment, referral to geriatrics or physical and/or occupational therapy, and measurement of 25-hydroxy vitamin D level. RESULTS: In our sample of older patients with cancer who reported at least one recent fall (N = 125), the average age was 72 years (range, 65 to 93 years), 78% were female, and 62% had a breast cancer diagnosis. Chart reviews showed that 13 (10%) had falls documented, 25 (20%) had a gait assessment, eight (6%) were referred, and 21 (17%) had vitamin D level measured. CONCLUSION: We found that only 10% of older patients with cancer who self-reported a recent fall had appropriate medical record documentation. Oncologists are often the primary care providers for older patients and are largely unfamiliar with the frequency and impact of falls in this population. There is a need to increase awareness of falls prevalence and consequences among oncology providers in order to provide timely interventions to reduce the risks associated with falls.

Geriatric assessment as an aide to understanding falls in older adults with cancer.

PURPOSE: In older adults, falls are a common cause of functional decline, institutionalization, and reduced quality of life. This study (1) investigates the prevalence of falls in a large sample of community-dwelling older adults with a cancer diagnosis and (2) evaluates the association of falls with domains of comprehensive geriatric assessment (CGA) that pertain to falls risk. METHODS: Patients completed a CGA that includes a self-reported measure of number of falls in the past 6 months. Summary statistics are used to describe prevalence of falls and associations with hypothesized risk factors using Fisher's exact tests and multivariable logistic regression. RESULTS: A total of 1172 patients were enrolled, mean age 73 (65-99), 74 % female, and 89 % Caucasian. Two hundred fifty-six (22 %) reported one or more falls within the last 6 months. Patients with at least one instrumental activities of daily living (IADL) or physical function deficit had more falls as compared those with no deficits identified (p ≤ 0.001). The number of daily medications, comorbidities, Timed Up and Go score >14 s, and poor vision were also associated with increased falls (p ≤ 0.001). Reduced physical function, poor vision, and low performance status had the highest adjusted odds ratio (3.6, 3.4, and 3.0, respectively) for falls. CONCLUSIONS: There is a high prevalence of falls in community-dwelling older patients with a cancer diagnosis. Falls are significantly associated with several measures of geriatric assessment including IADL, physical function, comorbidities, medications, and vision. Timely identification and management of risk factors for falls are important considerations in the care of older cancer patients.

Expedient synthesis and design strategies for new peptoid construction.

[reaction: see text] A range of peptoids can be prepared efficiently using microwave-assisted solid-phase chemistry in a commercial reactor. This method is most effective for the installation of electronically deactivated benzylic amines. The systematic incorporation of these amines into peptoids can deliver oligomers capable of displaying unique and stable structural motifs-microwave-assisted solid-phase synthesis will enable their future study and application.
