Cancer and frailty in older adults: a nested case-control study of the Mexican Health and Aging Study

The Lives of Older People With Advanced Cancer Who Live Alone During Outpatient Cancer Chemotherapy: A Descriptive Qualitative Study

Nursing care for older people with advanced cancer who live alone during outpatient chemotherapy should address their difficulties while respecting their lives. However, their lived experiences remain underexplored. Therefore, we conducted a descriptive qualitative study to explore and describe their lives. The participants were purposively sampled, older patients (≥ 65 years) with advanced cancer who lived alone and were receiving outpatient cancer chemotherapy. Semi-structured interviews were conducted using an interview guide, and thematic analysis was applied. There were 12 participants. Nine categories and 49 subcategories were extracted. The core category was "Getting by through endurance, ingenuity, and effort in one's increasingly fragile 'own vessel,' in order to survive a little longer and fulfill one's life." Effective support should not only address their challenges, but also respect their convictions, leverage their strengths, and enhance their self-efficacy. Further, early implementation of advance care planning (ACP) is crucial to proactively identify the needs of these patients, who rarely express their concerns. This approach facilitates their transition from full independence to autonomy, enabling them to choose and integrate necessary support into their daily lives.

Is Cancer Associated With Frailty? Results From a Longitudinal Study of Old Danish Twins

BACKGROUND

Although age is an important risk factor for both cancer and frailty, it is unclear whether cancer itself increases the risk of frailty. We aimed to assess the association between cancer and frailty in a longitudinal cohort of older Danish twins, taking familial effect into account.

METHODS

Using the Danish Cancer Registry, cancer cases were identified among participants aged 70 and over in the Longitudinal Study of Aging Danish Twins (LSADT). Frailty was evaluated over 10 years of follow-up using the frailty index (FI) and defined as FI > 0.21. Stratified Cox regressions were performed on discordant twin pairs (pairs where one twin had incident cancer and the other was cancer-free) and on all LSADT individual twins (twin pairs and singletons) with no history of cancer.

RESULTS

Among the 72 discordant pairs (n = 144, median age at inclusion = 75) included in the study, the median FI at inclusion was 0.08 for both cancer twins and cancer-free co-twins. From the stratified Cox regression, twins with cancer had an increased hazard of developing frailty (hazard ratio [HR] = 3.67, 95% confidence interval [CI] = 1.02-13.14) compared with their cancer-free co-twins. The analyses on individual twins (n = 4 027) provided similar results, showing an increased hazard of frailty in individuals with cancer (HR = 2.57, 95% CI = 1.77-3.74) compared with those without cancer.

CONCLUSIONS

We showed a higher risk of becoming frail following a cancer diagnosis in both discordant twin pairs and individual twins. These findings support the importance of monitoring frailty in older adults with cancer through geriatric assessments and the implementation of frailty interventions.

Impact of Cancer History on Temporal Changes in the Cardiopulmonary Exercise Test of Patients with Cardiovascular Disease

The elevated risk of cardiovascular disease (CVD) in cancer patients and survivors is likely the result of normal age-related pathologies coupled with the direct and indirect effects of cancer therapy that extend across multiple systems. The purpose of this study was to investigate the impact of cardiac rehabilitation (CR) on CVD patients with a history of cancer.In this study, patients who had participated in the outpatient CR program were enrolled and were divided into 2 groups (cancer survivor group and no-cancer group) based on their history of cancer. The cardiopulmonary exercise test (CPET) was performed at the beginning (baseline) and at the end of the CR program (follow-up). The results of CPET at baseline and those at follow-up were analyzed retrospectively.A total of 105 patients were analyzed in this study. The cancer survivor group had 25 patients, and the non-cancer group 80. At baseline, peak oxygen uptake (peak VO2) (14.7 [11.9 to 17.6] mL/kg/minute versus 11.3 [9.7 to 14.7] mL/kg/minute; P = 0.003) was significantly lower in cancer survivors. The percent changes in peak VO2 between baseline and follow-up were not significantly different between the 2 groups (7.9 % [-11.5 to 24.5] versus 9.4 % [-7.5 to 27.3] P = 0.520).The percent changes in peak VO2 of CR participants were not significantly different despite their cancer history.

Is There a Difference in Unmet Supportive Care Needs Between Older and Younger Outpatients Receiving Chemotherapy?

Objective: This study investigated whether there was a difference in unmet supportive care needs between older and younger cancer patients who receive chemotherapy. Background: Physiological, physical, cognitive, and social functions, which play a key role in coping with cancer, are impaired due to aging. Age-related physiological changes and psychosocial factors and comorbid medical conditions make some of the needs of older cancer patients unique and complex. At the heart of meeting these needs lies the concept of supportive care. First step of meeting their needs is to determine these needs. Study Design and Methods: The study was conducted in the Daytime Treatment Unit of the oncology hospital of a university in Ankara, Turkey. The study sample consisted of 93 patients aged 65 years or older and 93 patients under 65 years of age. Both groups were similar in terms of sex, cancer type, and chemotherapy protocols. Data were collected using a Patient Information Form and Supportive Care Needs Scale-Short Turkish Version and analyzed using descriptive statistics, Mann-Whitney U test, Kruskal-Wallis H test, and Bonferroni correction. Results: Participants had a median total score of 1.92. Their "daily life needs" and "sexuality needs" subscale scores were highest and lowest, respectively. Older patients had lower median total scores than younger patients. Younger patients had higher median "health care and information needs" and "sexuality needs" subscale scores than older patients. Conclusion: Elderly patients reported fewer unmet needs than younger patients. This may be due to age-related cultural factors as they may have difficulty expressing their needs. Implications: Results suggest to focus on the fact that patients' needs change with age and that they have difficulty expressing their needs.

How frail is frail in oncology studies? A scoping review

AIMS

The frailty index (FI) is one way in which frailty can be quantified. While it is measured as a continuous variable, various cut-off points have been used to categorise older adults as frail or non-frail, and these have largely been validated in the acute care or community settings for older adults without cancer. This review aimed to explore which FI categories have been applied to older adults with cancer and to determine why these categories were selected by study authors.

METHODS

This scoping review searched Medline, EMBASE, Cochrane, CINAHL, and Web of Science databases for studies which measured and categorised an FI in adults with cancer. Of the 1994 screened, 41 were eligible for inclusion. Data including oncological setting, FI categories, and the references or rationale for categorisation were extracted and analysed.

RESULTS

The FI score used to categorise participants as frail ranged from 0.06 to 0.35, with 0.35 being the most frequently used, followed by 0.25 and 0.20. The rationale for FI categories was provided in most studies but was not always relevant. Three of the included studies using an FI > 0.35 to define frailty were frequently referenced as the rationale for subsequent studies, however, the original rationale for this categorisation was unclear. Few studies sought to determine or validate optimum FI categorises in this population.

CONCLUSION

There is significant variability in how studies have categorised the FI in older adults with cancer. An FI ≥ 0.35 to categorise frailty was used most frequently, however an FI in this range has often represented at least moderate to severe frailty in other highly-cited studies. These findings contrast with a scoping review of highly-cited studies categorising FI in older adults without cancer, where an FI ≥ 0.25 was most common. Maintaining the FI as a continuous variable is likely to be beneficial until further validation studies determine optimum FI categories in this population. Differences in how the FI has been categorised, and indeed how older adults have been labelled as 'frail', limits our ability to synthesise results and to understand the impact of frailty in cancer care.

Experiences and views of nurses about unmet needs of older cancer patients receiving chemotherapy: A qualitative study

OBJECTIVE

The aim is to understand the experiences and views of oncology nurses about the unmet care needs of older cancer patients receiving chemotherapy. Nurses play the key role in evaluating and determining the needs of this special group.

METHOD

A phenomenological descriptive qualitative study with convenience sampling was used. Participants were referred by the Turkish Oncology Nursing Society. The study participants were 12 nurses aged 34-53 years, with oncology experience between 5 and 27 years. The data were collected using semi-structured face-to-face interviews. Interviews were transcribed verbatim with concurrent analyses and data collection. Thematic content analysis was used to determine common domains.

RESULTS

The study data were categorized into 3 contexts, 12 themes, and 37 subthemes. The first context, "unmet needs", includes physical care, psychological care, and social care themes. The second context, "barriers to meeting those needs", comprises the theme of patient characteristics, attitude of family, attitude of the nurses/healthcare team, health system, and culture. The last context is "suggestions for meeting needs". Nurses play an important role in identifying and meeting unmet psychosocial needs.

SIGNIFICANCE OF RESULTS

The study indicated that older cancer patients had problems in identifying, expressing, and making demands for their needs and that their culture contributed to this situation. Nurses serving in the outpatient chemotherapy units should conduct a holistic assessment of older cancer patients, be aware that these patients may not be able to express their needs, be more sensitive toward them, and ensure that the voice of the older patients is heard.

Symptoms and experiences of frailty in lung cancer patients with chemotherapy: A mixed-method approach

Objective

The aim of this study was to explore the symptoms and experiences of frailty in lung cancer patients treated with chemotherapy.

Methods

Quantitative and qualitative research methods were implemented. A total of 302 patients aged > 18 years were recruited by convenience sampling method. Quantitative data were collected through the General Demographic Characteristics questionnaire, the Frailty Phenotype scale, the Cancer Fatigue Scale, the Hospital Anxiety and Depression Scale and the Pittsburgh Sleep Quality Index. Fourteen patients with a score of Frailty Phenotype scale ≥ 3 were drawn and their interviews were thematically analyzed.

Results

The mean Frailty Phenotype score was (1.63±1.35), suggesting that most of the patients were in pre-frailty conditions. A total of 64 (21.2%) patients were non-frail, 168 (55.6%) patients were pre-frail, 70 (23.2%) patients were frail. The mean CFS, HADS scores, and PSQI scores were (26.86±8.93), (15.42±9.73), and (6.18±4.39), respectively. The Number of chemotherapy times was positively associated with frailty. Anxiety fatigue, depression and poor sleep quality positively correlated with frailty. The qualitative research showed four themes. Theme 1: the most reported symptoms of frailty were physical symptoms and psychological symptoms. Physical symptoms included fatigue, low physical activity, weight loss and poor sleep quality. Psychological symptoms included anxiety, depression and low social activities. Theme 2: frailty was mainly related to lung cancer and chemotherapeutic drugs, which can cause decreased appetite, constipation and altered taste. Theme 3: patients used bad coping strategies to manage the symptoms of frailty. Theme 4: the social support of patients was weak, especially regarding emotional support.

Conclusion

The most frequent symptoms reported by lung cancer patients treated with chemotherapy were anxiety, fatigue, depression, low physical activity and poor sleep quality. Patients also complained of bad coping strategies and weak support. Medical staff should strengthen the management of frailty, aiming at improving the quality of life in lung cancer patients treated with chemotherapy.

The Therapeutic Potential of the Endocannabinoid System in Age-Related Diseases

The endocannabinoid system (ECS) dynamically regulates many aspects of mammalian physiology. ECS has gained substantial interest since growing evidence suggests that it also plays a major role in several pathophysiological conditions due to its ability to modulate various underlying mechanisms. Furthermore, cannabinoids, as components of the cannabinoid system (CS), have proven beneficial effects such as anti-inflammatory, immunomodulatory, neuromodulatory, antioxidative, and cardioprotective effects. In this comprehensive review, we aimed to describe the complex interaction between CS and most common age-related diseases such as neuro-degenerative, oncological, skeletal, and cardiovascular disorders, together with the potential of various cannabinoids to ameliorate the progression of these disorders. Since chronic inflammation is postulated as the pillar of all the above-mentioned medical conditions, we also discuss in this paper the potential of CS to ameliorate aging-associated immune system dysregulation.

Chronic kidney disease in the context of multimorbidity patterns: the role of physical performance : The screening for CKD among older people across Europe (SCOPE) study

Background

Chronic kidney disease (CKD) is known to be associated with several co-occurring conditions. We aimed at exploring multimorbidity patterns associated with CKD, as well as the impact of physical performance and CKD severity on them in a population of older outpatients.

Methods

Our series consisted of 2252 patients enrolled in the Screening of CKD among Older People across Europe multicenter observational study. Hypertension, stroke, transient ischemic attack, cancer, hip fracture, osteoporosis, Parkinson’s disease, asthma, chronic obstructive pulmonary disease, congestive heart failure, angina, myocardial infarction, atrial fibrillation, anemia, CKD (defined as GFR < 60, < 45 or < 30 ml/min/1.73 m²), cognitive impairment, depression, hearing impairment and vision impairment were included in the analyses. Physical performance was assessed by the Short Physical Performance Battery (SPPB) and used as stratification variable. Pairs of co-occurring diseases were analyzed by logistic regression. Patterns of multimorbidity were investigated by hierarchical cluster analysis.

Results

CKD was among the most frequently observed conditions and it was rarely observed without any other co-occurring disease. CKD was significantly associated with hypertension, anemia, heart failure, atrial fibrillation, myocardial infarction and hip fracture. When stratifying by SPPB, CKD was also significantly associated with vision impairment in SPPB = 5–8 group, and hearing impairment in SPPB = 0–4 group. Cluster analysis individuated two main clusters, one including CKD, hypertension and sensory impairments, and the second including all other conditions. Stratifying by SPPB, CKD contribute to a cluster including diabetes, anemia, osteoporosis, hypertension and sensory impairments in the SPPB = 0–4 group. When defining CKD as eGFR< 45 or 30 ml/min/1.73 m², the strength of the association of CKD with hypertension, sensory impairments, osteoporosis, anemia and CHF increased together with CKD severity in pairs analysis. Severe CKD (eGFR< 30 ml/min/1.73 m²) contributed to a wide cluster including cardiovascular, respiratory and neurologic diseases, as well as osteoporosis, hip fracture and cancer.

Conclusions

CKD and its severity may contribute significantly to specific multimorbidity patterns, at least based on the cluster analysis. Physical performance as assessed by SPPB may be associated with not negligible changes in both co-occurring pairs and multimorbidity clusters.

Association of Prediagnostic Frailty, Change in Frailty Status, and Mortality After Cancer Diagnosis in the Women's Health Initiative

IMPORTANCE

Understanding changes in frailty in relation to cancer diagnosis can inform optimal selection of cancer treatments and survivorship care.

OBJECTIVE

To investigate associations of prediagnostic frailty and change in frailty status with mortality after a cancer diagnosis.

DESIGN, SETTING, AND PARTICIPANTS

This multicenter, prospective cohort study included 7257 community-dwelling, postmenopausal women in the United States who had frailty assessed at the Women's Health Initiative (WHI) enrollment (1993-1998) and the 3-year visit who were subsequently diagnosed as having invasive cancer. The data were analyzed from January 7, 2019, to June, 8, 2020.

EXPOSURE

Frailty scores were defined from validated questionnaire items conceptually aligned with the Fried frailty phenotype, including at least 3 of the following characteristics: self-reported unintentional weight loss, exhaustion, low physical activity, and muscle weakness or impaired walking. Physical function components of the frailty score were updated a median of 10 (range, 1-18) times.

MAIN OUTCOMES AND MEASURES

Using multivariable-adjusted Cox proportional hazards models, this study examined associations of prediagnostic frailty (at the 3-year visit, before cancer diagnosis) and prediagnostic changes in frailty (from enrollment to the 3-year visit) with mortality. Women were followed up beginning from cancer diagnosis for mortality outcomes through March 2018. In linear mixed-effects models with frailty scores as a function of time since cancer diagnosis, this study evaluated whether the time slope, ie, the rate of change in frailty score, increased after cancer diagnosis.

RESULTS

This study included 7257 women in the WHI cohort who completed frailty assessments at enrollment and the 3-year WHI visit before cancer diagnosis and subsequently developed cancer. Cancer cases included 2644 breast cancers (36%), 822 lung cancers (11%), 691 colorectal cancers (10%), 445 endometrial cancers (6%), and 286 ovarian cancers (4%). At the 3-year visit, prior to cancer diagnosis, the mean (SD) age was 63 (7) years, and 1161 of 7257 (16%) of participating women met criteria for frailty; 2129 of 7257 (29%) were prefrail, and 3967 of 7257 (55%) were nonfrail. Over a median follow-up of 5.8 years after cancer diagnosis (range, 1 day to 19.9 years), 3056 women died. After multivariable adjustment, women who were frail (vs nonfrail) before cancer diagnosis had an increased risk of mortality after cancer diagnosis (hazard ratio [HR], 1.40; 95% CI, 1.26-1.55; P for trend <.001). Sustained frailty (21% [1537 of 7257] of women) or worsening frailty (22% [1578 of 7257]) vs being consistently nonfrail (45% [3266 of 7257]) before cancer diagnosis increased the risk of mortality after cancer diagnosis (HR, 1.25; 95% CI, 1.14-1.38 and 1.22; 95% CI, 1.11-1.34, respectively; P for trend <.001). In linear mixed-effects models, the rate of increase in physical frailty over time was statistically significantly higher after cancer diagnosis.

CONCLUSIONS AND RELEVANCE

Sustained and worsening frailty before cancer diagnosis was associated with an increased risk of mortality after cancer diagnosis in postmenopausal women. Furthermore, the rate of decline in physical function accelerated after cancer diagnosis. Frailty assessment could provide valuable information and perhaps prompt interventions to reduce and preempt worsening of physical frailty after cancer diagnosis.

Geriatric oncology: assessing the needs of older people with cancer

A majority of cancer cases now occur among older people, but this group is less likely to receive treatment and outcomes are poorer than in younger people. Age by itself can be a poor predictor of who will benefit from treatment with surgery, chemotherapy or radiotherapy. Comprehensive geriatric assessment is a multidisciplinary, multidomain process that helps to identify frailty, which is associated with increased mortality. Comprehensive geriatric assessment highlights areas that should be optimized before treatment and helps support a shared decision-making approach. Geriatricians, oncologists and surgeons now work together to help assess and support older people with cancer.

Mediating Effects of Frailty Indicators on the Risk of Sepsis After Cancer

BACKGROUND

Cancer survivors are at increased risk of sepsis, possibly attributed to weakened physiologic conditions. The aims of this study were to examine the mediation effect of indicators of frailty on the association between cancer survivorship and sepsis incidence and whether these differences varied by race.

METHODS

We performed a prospective analysis using data from the REasons for Geographic and Racial Differences in Stroke cohort from years 2003 to 2012. We categorized frailty as the presence of ≥2 frailty components (weakness, exhaustion, and low physical activity). We categorized participants as "cancer survivors" or "no cancer history" derived from self-reported responses of being diagnosed with any cancer. We examined the mediation effect of frailty on the association between cancer survivorship and sepsis incidence using Cox regression. We repeated analysis stratified by race.

RESULTS

Among 28 062 eligible participants, 2773 (9.88%) were cancer survivors and 25 289 (90.03%) were no cancer history participants. Among a total 1315 sepsis cases, cancer survivors were more likely to develop sepsis (12.66% vs 3.81%, P < .01) when compared to participants with no cancer history (hazard ratios: 2.62, 95% confidence interval: 2.31-2.98, P < .01). The mediation effects of frailty on the log-hazard scale were very small: weakness (0.57%), exhaustion (0.31%), low physical activity (0.20%), frailty (0.75%), and total number of frailty indicators (0.69%). Similar results were observed when stratified by race.

CONCLUSION

Cancer survivors had more than a 2-fold increased risk of sepsis, and indicators of frailty contributed to less than 1% of this disparity.

Frailty syndrome in ambulatory patients with COPD

Frailty is a state of increased risk of unfavorable outcomes when exposed to stressors, and COPD is one of the several chronic illnesses associated with the condition. However, few studies have been conducted regarding the prevalence of COPD and its related factors in Southeast Asia. The objectives of this study were to determine the prevalence of frailty in COPD patients and to identify the associated factors in these populations. A cross-sectional study of COPD patients who attended a COPD clinic was conducted from May 2015 to December 2016. Baseline characteristics were collected, and the diagnosis of frailty was based on the FRAIL (fatigue, resistance, ambulation, illnesses, and loss of weight) scale. Descriptive statistics were used to analyze baseline data. Factors associated with frailty were analyzed using univariate and multivariate regression analyses. The results showed that the prevalence rates of frailty and pre-frailty were 6.6% (eight out of 121 cases) and 41.3% (50 out of 121 cases), respectively, among COPD patients. Fatigue was the most common component of the FRAIL scale that was found more frequently in frail patients than in non-frail patients (odds ratio [OR] 91.9). Factors associated with frailty according to multivariate analyses were comorbid cancer (adjusted OR [AOR] 45.8), at least two instances of nonelective admission over the past 12 months (AOR 112.5), high waist circumference (WC) (AOR 1.3), and presence of sarcopenia (AOR 29.5). In conclusion, frailty affected 6.6% of stable COPD patients. Cancer, two or more instances of nonelective hospitalization over the past 12 months, high WC, and presence of sarcopenia were associated with frailty. Early identification and intervention in high-risk patients is recommended to prevent or delay the adverse outcomes of frailty.

Disability and quality of life in community-dwelling elderly cancer survivors: Case-control study in the Korean population

PURPOSE

Advanced age is a significant risk factor for cancer and functional disabilities increase with age. The purpose of this case-control study of Korean individuals was to determine the effect of cancer and cancer treatment on functional disability and quality of life (QOL). Thus, we compared community-dwelling elderly cancer patients (ECPs) with individuals from the general elderly population (GEP) who never had diagnoses of cancer.

METHODS

We selected 1776 ECP who were at least 65 years-old from the 2008 Korean Community Health Survey data and used propensity score matching to randomly select 1766 individuals from the GEP who closely resembled the ECPs. Functional disability was measured using the Instrumental Activities of Daily Living (IADL) scale, and QOL was measured by the EuroQol Group EQ-5D.

RESULTS

ECPs were more dependent in preparation of food, doing laundry, and shopping (IADL scale), and in mobility and usual activities (EQ-5D). Although ECP had more problems with pain, discomfort, anxiety, and depression, they were more independent in self-care and handling of financial responsibilities.

CONCLUSIONS

ECPs had multiple physical and psychological symptoms that adversely affected functional disability and QOL, but higher functional ability, such as self-care and handling of financial responsibilities. Promotion of self-care by ECPs is pivotal for effective management in community practice.
