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

The current status of geriatric oncology in India

Geriatric oncology in India is relatively new. The number of older persons with cancer is increasing exponentially; at our institution, 34% of patients registered are 60 years and over. Apart from the Tata Memorial Hospital in Mumbai, there are currently no other Indian centers that have a dedicated geriatric oncology unit. Geriatric assessments (GAs) are done sporadically, and older patients with cancer are usually assessed and treated based on clinical judgement. Challenges to increasing the uptake of GA include a lack of training/time/interest or knowledge of the importance of the GA. Other challenges include a lack of trained personnel with expertise in geriatric oncology, and a paucity of research studies that seek to advance the outcomes in older Indian patients with cancer. We anticipate that over the next 10 years, along with the inevitable increase in the number of older persons with cancer in India, there will be a commensurate increase in the number of skilled personnel to care for them. Key goals for the future include increased research output, increased number of dedicated geriatric oncology units across the country, India-specific geriatric oncology guidelines, geriatric oncology training programs, and a focus on collaborative work across India and with global partners. In this narrative review, we provide a broad overview of the status of geriatric oncology in India, along with a description of the work done at our center. We hope to spark interest and provide inspiration to readers to consider developing geriatric oncology services in other settings.

Presentation, Molecular Characteristics, Treatment, and Outcomes of Colorectal Cancer in Patients Older than 80 Years Old

Background: An increasing proportion of the population of patients with cancer presents at an advanced age, increasing the challenges of successful and well-tolerated treatments. In the older spectrum of the geriatric cancer patients, those older than 80 years old, challenges are even higher because of increasing comorbidities and decreasing organ function reserves. Methods: Studies regarding colorectal cancer presentation, treatment, and prognosis in patients older than 80 years old available in the literature were evaluated and were compiled within a narrative review. Molecular attributes of colorectal cancer in the subset of patients older than 80 years old in published genomic cohorts were also reviewed and were compared with similar attributes in younger patients. Results: Characteristics of colorectal cancer in octogenarians are in many aspects similar to younger patients, but patients older than 80 years old present more often with right colon cancers. Surgical treatment of colorectal cancer in selected patients over 80 years old is feasible and should be pursued. Adjuvant chemotherapy is under-utilized in this population. Although combination chemotherapy is in most cases not advisable, monotherapy with fluoropyrimidine derivatives is feasible and efficacious. Conclusions: Outcomes of colorectal cancer patients over the age of 80 years old may be optimized with a combination of standard treatments adjusted to the individual patient's functional status and organ reserves. Increased support for the older age group during their colorectal cancer treatment modalities would improve oncologic outcomes with decreasing adverse outcomes of therapies.

The early predictive value of frailty for health-related quality of life among elderly patients with cancer receiving curative chemotherapy

Changes in health-related quality of life (HRQOL) among elderly patients with cancer before and after receiving curative treatment, such as chemotherapy, have always been an important consideration in physician-patient treatment decision-making. Although frailty assessment can help predict the effects of chemotherapy, there is a lack of relevant literature on its effectiveness in predicting post-chemotherapy HRQOL. Therefore, this study investigated the early predictive value of pre-chemotherapy frailty assessment for post-chemotherapy HRQOL among elderly patients with cancer receiving curative chemotherapy. From September 2016 to November 2018, this study enrolled elderly patients with cancer aged ≥ 65 years (N = 178), who were expected to receive chemotherapy at three hospitals in Taiwan. The mean age of patients was 71.70 years (SD = 5.46 years) and half of them were female (n = 96, 53.9%). A comprehensive geriatric assessment was performed to measure frailty in 178 participants one week before receiving chemotherapy (T0). Further, the HRQOL of the elderly patients with cancer was assessed again, four weeks after chemotherapy (T1). After controlling for demographic variables, this study evaluated the predictive value of frailty for HRQOL using a hierarchical regression analysis. A total of 103 (57.9%) participants met the frailty criteria. The results showed that 31.1%-56.7% of the variance in the seven domains of HRQOL could be explained by demographic variables and the presence or absence of frailty. This suggests that the presence or absence of frailty is an important predictor of the illness burden domain (β = 9.5; p < .05) of HRQOL. Frailty affects the illness burden domain of HRQOL in elderly patients with cancer. Finally, the administration of frailty assessments before treatment is recommended as a reference for patient treatment decision-making.

An age-group analysis on the efficacy of chemotherapy in older adult patients with metastatic biliary tract cancer: a Japanese cancer registry cohort study

BACKGROUND

The effectiveness of chemotherapy in older adult patients with biliary tract cancer (BTC) remains to be established, despite the fact that the majority of patients diagnosed with BTC tend to be aged ≥ 70 years. In this study, we used three databases to examine the effectiveness of chemotherapy in a large patient population aged ≥ 70 years with metastatic BTC.

METHODS

Using a large Japanese database that combined three data sources (Osaka Cancer Registry, Japan's Diagnosis Procedure Combination, the hospital-based cancer registry database), we extracted the data from patients pathologically diagnosed with metastatic BTC, between January 1, 2013, and December 31, 2015, in 30 designated cancer care hospitals (DCCHs). A cohort of patients with comparable backgrounds was identified using propensity score matching. The log-rank test was used to examine how chemotherapy affected overall survival (OS).

RESULTS

Among 2,622 registered patients with BTC in 30 DCCHs, 207 older adult patients aged > 70 years with metastatic BTC were selected. Chemotherapy significantly improved the prognosis of older adult patients, according to propensity score matching (chemotherapy, 6.4 months vs. best supportive care, 1.8 months, P value < 0.001). The number of patients receiving chemotherapy tends to decrease with age. Gemcitabine plus cisplatin (GC) and gemcitabine plus S-1 (oral fluoropyrimidine) (GS) combination therapy were frequently performed in the chemotherapy group for patients under 80 years of age (70-74 years, 61.7%; 75-79 years, 62.8%). In contrast, monotherapy including GEM and S-1 was more frequently performed in age groups over 80 years (80-84 years, 56.2%; 85-89 years, 77.7%; ≥90 years, 100%). In the chemotherapy group among older adult patients aged < 85 years, the median OS was significantly longer according to age-group analysis of the 5-year age range following propensity score matching.

CONCLUSIONS

In older adult patients with metastatic BTC who received chemotherapy, prolonged survival was observed. Chemotherapy may be a viable option for patients with metastatic BTC who are aged < 85 years.

Priority of the basic and instrumental activities of daily living in older patients with cancer prescribed rehabilitation: a cross-sectional survey

BACKGROUND

There is no information on whether vulnerable older patients with cancer consider basic activities of daily living (BADL) and instrumental activities of daily living (IADL) important outcomes. Our survey aimed to investigate the priority of BADL and IADL in outcomes among vulnerable older patients with cancer.

METHODS

This was a single-center survey in a Japanese cancer center. Eligible patients were ≥ 65 years of age and were prescribed in-hospital rehabilitation while under cancer treatment. Using original self-administered ranking questionnaires, patients were asked to rank outcomes and subdomain of BADL and IADL. High-priority domains were defined as the highest, second-highest, and third-highest priority domains in individuals.

RESULTS

A total of 169 patients were analyzed. The mean age was 74.0 years (standard deviation, 5.1 years) and the number of males was 107 (63%). The order of ranking of high-priority outcomes was BADL and IADL (n = 155), cognitive function (n = 91), mental function (n = 82), nutrition (n = 61), social function (n = 51), comorbidity (n = 39), and life span (n = 28). The top three high-priority independence subdomains of BADL and IADL were toilet use (n = 140), feeding (n = 134), and mobility (n = 69) among the BADL and shopping (n = 93), food preparation (n = 88), and ability to handle finances (n = 85) among the IADL.

CONCLUSIONS

BADL and IADL can be considered the most important health outcomes in clinical trials and in practice among older patients with cancer and physical vulnerabilities.

Communication Barriers in Oncology Care for Elderly Deaf Patients: A Daughter's Narrative and Call for Tailored Medical Services

My father is deaf. A year ago, he was diagnosed with Hodgkin lymphoma. Most patients with hearing disabilities suffer from a lack of access to health care in a form that ensures they receive a rapid diagnosis, correct and effective treatment, and medical treatment options they understand. The minimal evidence that exists is associated with the timeliness of a cancer diagnosis, therapy, and consequences for these patients. We must give them the appropriate treatment for their disease and include them in clinical trials if they will benefit from them and provide health care workers training and tools on how to communicate better with these patients.

Endometrial Cancer. Guideline of the DGGG, DKG and DKH (S3-Level, AWMF Registry Number 032/034-OL, September 2022). Part 1 with Recommendations on the Epidemiology, Screening, Diagnosis and Hereditary Factors of Endometrial Cancer, Geriatric Assessment and Supply Structures

Summary The S3-guideline on endometrial cancer, first published in April 2018, was reviewed in its entirety between April 2020 and January 2022 and updated. The review was carried out at the request of German Cancer Aid as part of the Oncology Guidelines Program and the lead coordinators were the German Society for Gynecology and Obstetrics (DGGG), the Gynecology Oncology Working Group (AGO) of the German Cancer Society (DKG) and the German Cancer Aid (DKH). The guideline update was based on a systematic search and assessment of the literature published between 2016 and 2020. All statements, recommendations and background texts were reviewed and either confirmed or amended. New statements and recommendations were included where necessary. Aim The use of evidence-based risk-adapted therapies to treat women with endometrial cancer of low risk prevents unnecessarily radical surgery and avoids non-beneficial adjuvant radiation therapy and/or chemotherapy. For women with endometrial cancer and a high risk of recurrence, the guideline defines the optimum level of radical surgery and indicates whether chemotherapy and/or adjuvant radiation therapy is necessary. This should improve the survival rates and quality of life of these patients. The S3-guideline on endometrial cancer and the quality indicators based on the guideline aim to provide the basis for the work of certified gynecological cancer centers. Methods The guideline was first compiled in 2018 in accordance with the requirements for S3-level guidelines and was updated in 2022. The update included an adaptation of the source guidelines identified using the German Instrument for Methodological Guideline Appraisal (DELBI). The update also used evidence reviews which were created based on selected literature obtained from systematic searches in selected literature databases using the PICO process. The Clinical Guidelines Service Group was tasked with carrying out a systematic search and assessment of the literature. Their results were used by interdisciplinary working groups as a basis for developing suggestions for recommendations and statements which were then modified during structured online consensus conferences and/or additionally amended online using the DELPHI process to achieve a consensus. Recommendations Part 1 of this short version of the guideline provides recommendations on epidemiology, screening, diagnosis, and hereditary factors. The epidemiology of endometrial cancer and the risk factors for developing endometrial cancer are presented. The options for screening and the methods used to diagnose endometrial cancer are outlined. Recommendations are given for the prevention, diagnosis, and therapy of hereditary forms of endometrial cancer. The use of geriatric assessment is considered and existing structures of care are presented.

The Impact of Age in the Treatment of Non-comorbid Patients with Rectal Cancer: Survival Outcomes from the National Cancer Database

BACKGROUND

Multimodal therapy has improved survival outcomes for rectal cancer (RC) significantly with an exemption for older patients. We sought to assess whether older non-comorbid patients receive substandard oncological treatment for localized RC referring to the National Comprehensive Cancer Network (NCCN) guidelines and whether it affects survival outcomes.

METHODS

This is a retrospective study using patient data from the National Cancer Data Base (NCDB) for histologically confirmed RC from 2002 to 2014. Non-comorbid patients between ≥50 and ≤85 years and defined treatment for localized RC were included and assigned to a younger (<75 years) and an older group (≥75 years). Treatment approaches and their impact on relative survival (RS) were analyzed using loess regression models and compared between both groups. Furthermore, mediation analysis was performed to measure the independent relative effect on age and other variables on RS. Data were assessed using the Strengthening the Reporting of Observational studies in Epidemiology (STROBE) checklist.

RESULTS

Of 59,769 included patients, 48,389 (81.0%) were assigned to the younger group (<75 years). Oncologic resection was performed in 79.6% of the younger patients compared to 67.2% of the older patients (p < 0.001). Chemotherapy (74.3% vs. 56.1%) and radiotherapy (72.0% vs. 58.1%) were provided less often in older patients, respectively (p < 0.001). Increasing age was associated with enhanced 30- and 90-day mortality with 0.6% and 1.1% in the younger and 2.0% and 4.1% in the elderly group (p < 0.001) and worse RS rates [multivariable adjusted HR: 1.93 (95% CI 1.87-2.00), p < 0.001]. Adherence to standard oncological therapy resulted in a significant increase in 5-year RS (multivariable adjusted HR: 0.80 (95% CI 0.74-0.86), p < 0.001). Mediation analysis revealed that RS was mainly affected by age itself (84%) rather than the choice of therapy.

CONCLUSIONS

The likelihood to receive substandard oncological therapy increases in the older population and negatively affects RS. Since age itself has a major impact on RS, better patient selection should be performed to identify those that are potentially eligible for standard oncological care regardless of their age.

Geriatric Oncology in the Instagram Era: Feasibility and Acceptability Randomised Controlled Trial on Adopting PhotoVoice to Enable Empowerment, Patient-Centred Care, and Shared Decision Making-Study Protocol

Geriatric assessment (GA) is fundamental to optimising cancer care in older adults, yet implementing comprehensive GA tools in real-world clinical settings remains a challenge. This study aims to assess the feasibility and acceptability of integrating information from patient-derived photographs (PhotoVoice) into enhanced supportive care (ESC) for older adults with cancer. A feasibility randomised controlled trial will be conducted at a regional cancer care centre in Australia. Participants aged 70 and above will be randomised into two groups: PhotoVoice plus ESC or usual care (ESC) alone. In the PhotoVoice group, participants will provide four photographs for deduction of representations of different aspects of their lives using photo-elicitation techniques. ESC will be conducted for both groups, incorporating PhotoVoice analysis in the intervention group. PhotoVoice may improve patient-centred care outcomes, including enhanced communication, shared decision making, and identification of patient priorities and barriers. Findings will provide insights into implementing PhotoVoice in geriatric assessment and guide future trials in cancer among older adults.

Health-related quality of life and vulnerability among people with myelodysplastic syndromes: a US national study

Health-related quality of life (HRQoL) and vulnerability are variably affected in patients with myelodysplastic syndromes (MDS) and other cytopenic states; however, the heterogeneity of these diseases has limited our understanding of these domains. The National Heart, Lung, and Blood Institute-sponsored MDS Natural History Study is a prospective cohort enrolling patients undergoing workup for suspected MDS in the setting of cytopenias. Untreated patients undergo bone marrow assessment with central histopathology review for assignment as MDS, MDS/myeloproliferative neoplasm (MPN), idiopathic cytopenia of undetermined significance (ICUS), acute myeloid leukemia (AML) with <30% blasts, or "At-Risk." HRQoL data are collected at enrollment, including the MDS-specific Quality of Life in Myelodysplasia Scale (QUALMS). Vulnerability is assessed with the Vulnerable Elders Survey. Baseline HRQoL scores from 449 patients with MDS, MDS/MPN, AML <30%, ICUS or At-Risk were similar among diagnoses. In MDS, HRQoL was worse for vulnerable participants (eg, mean Patent-Reported Outcomes Management Information Systems [PROMIS] Fatigue of 56.0 vs 49.5; P < .001) and those with worse prognosis (eg, mean Euroqol-5 Dimension-5 Level [EQ-5D-5L] of 73.4, 72.7, and 64.1 for low, intermediate, and high-risk disease; P = .005). Among vulnerable MDS participants, most had difficulty with prolonged physical activity (88%), such as walking a quarter mile (74%). These data suggest that cytopenias leading to MDS evaluation are associated with similar HRQoL, regardless of eventual diagnosis, but with worse HRQoL among the vulnerable. Among those with MDS, lower-risk disease was associated with better HRQoL, but the relationship was lost among the vulnerable, showing for the first time that vulnerability trumps disease risk in affecting HRQoL. This study is registered at www.clinicaltrials.gov as NCT02775383.

Accumulation of Chronic Disease Among Survivors of Childhood Cancer Predicts Early Mortality

PURPOSE

Cancer survivors develop cancer and treatment-related morbidities at younger than normal ages and are at risk for early mortality, suggestive of an aging phenotype. The Cumulative Illness Rating Scale for Geriatrics (CIRS-G) is specifically designed to describe the accumulation of comorbidities over time with estimates of severity such as total score (TS) which is a sum of possible conditions weighted by severity. These severity scores can then be used to predict future mortality.

METHODS

CIRS-G scores were calculated in cancer survivors and their siblings from Childhood Cancer Survivor Study cohort members from two time points 19 years apart and members of the National Health and Nutrition Examination Survey (NHANES) from 1999 to 2004. CIRS-G metrics were analyzed using Cox proportional hazards regression to determine subsequent mortality risk.

RESULTS

In total, 14,355 survivors with a median age of 24 (IQR, 18-30) years and 4,022 siblings with a median age of 26 (IQR, 19-33) years provided baseline data; 6,138 survivors and 1,801 siblings provided follow-up data. Cancer survivors had higher median baseline TS than siblings at baseline (5.75 v 3.44) and follow-up (7.76 v 4.79), all P < .01. The mean increase in TS from baseline to follow-up was significantly steeper in cancer survivors (2.89 males and 3.18 females) vs. siblings (1.79 males and 1.69 females) and NHANES population (2.0 males and 1.94 females), all P < .01. Every point increase in baseline TS increased hazard for death by 9% (95% CI, 8 to 10) among survivors.

CONCLUSION

Application of a geriatric rating scale to characterize disease supports the hypothesis that morbidity accumulation is accelerated in young adult survivors of childhood cancer when compared with siblings and the general population.

Geriatric assessment prior to cancer treatment: A health economic evaluation

INTRODUCTION

To address uncertainty regarding the cost-effectiveness of implementing geriatric assessment (GA) in oncology practice, we undertook a synthetic, model-based economic evaluation.

MATERIALS AND METHODS

A decision-analytic model with embedded Markov chains was developed to simulate a cost-effectiveness analysis of implementing GA within standard oncological care compared to current practice. This was for patients aged 77 years (the mean age in included trials) receiving chemotherapy or surgery as first-line treatment. Assumptions were made about model parameters, based on available literature, to calculate the incremental net health benefit (INHB) of GA, using a data synthesis.

RESULTS

GA has additional costs over standard care alone of between £390 and £576, depending upon implementation configuration. When major assumptions about the effectiveness of GA were modelled, INHB was marginally positive (0.09-0.12) at all cost-effectiveness thresholds (CETs). If no reduction in postoperative complications was assumed, the intervention was shown not to be cost-effective (INHB negative at all CETs). When used before chemotherapy, with minimal healthcare staffing inputs and technological assistance, GA is cost-effective (INHB positive between 0.06 and 0.07 at all CETs).

DISCUSSION

Considering emerging evidence that GA improves outcomes in oncology, GA may not be a cost-effective intervention when used for all older adults with cancer. However, with judicious selection of implementation models, GA has the potential to be cost-effective. Due to significant heterogeneity and centre dependent success in implementation and effectiveness, GA is difficult to study in oncology settings. Stakeholders could take a pragmatic approach towards GA introduction with local evaluation favoured over generalisable research. Because GA tends towards utilitarianism and has no safety issues, it is a suitable intervention for more widespread implementation.

Improving care for older adults with hematological malignancies in India: Conquering the challenge

In India, the number of older adults is steadily increasing and expected to reach around 200 million by 2030. Along with demographic change, India is experiencing a shift in family structure from multi-generational to nuclear families, affecting the social and psychological support available to older adults. The majority of hematological malignancies are diagnosed after the age of 60 years. Multiple issues associated with ageing, denoted as geriatric impairments, adversely affect the care of patients with cancer. Geriatric assessment and management is conspicuously underutilized and missing from the medical education curriculum in developing countries including India. Geriatric assessments may provide valuable information for the care of older adults with hematological malignancies, but incorporating geriatrics into the care of older patients with cancer in India will require knowledge of different approaches and consideration of the local healthcare context. In this article we will discuss the distinctive considerations in caring for older adults with hematological malignancies in India and to examine the unmet needs, challenges, and opportunities in improving the care of this population in the Indian context.

Preserving bone in cancers of the elderly: A necessity

The occurrence of bone fractures is frequent in the elderly population, and in cancer patients, especially with bone metastases. The growing incidence of cancer associated with an aging population implies important health challenges, including bone health. Decisions on cancer care in older adults have to take into account older adults' specificities. Screening tools as G8 or VES 13 and evaluating tools as comprehensive geriatric assessment (CGA) do not include bone-related items. Bone risk assessment is indicated according to identification of geriatric syndromes such as falls, history, and the oncology treatment plan. Some cancer treatments disrupt bone turnover and decrease bone mineral density. This is mainly caused by hypogonadism, induced by hormonal treatments and some chemotherapies. Treatments can also cause direct (i.e., chemotherapy, radiotherapy or glucocorticoids) or indirect toxicity through electrolyte disorders (i.e., some chemotherapies or tyrosine kinase inhibitors) on bone turnover. Bone risk prevention is multidisciplinary. Certain interventions proposed in the CGA aim to improve bone health and reduce the risk of falling. It is also based on the drug management of osteoporosis, and the prevention of complications from bone metastases. Management of fractures, related or not to bone metastases relates to the concept of orthogeriatrics. It is also based on the benefit-risk ratio of the operation, access to minimally invasive techniques, prehabilitation or rehabilitation, but also the prognosis related to cancer and geriatric syndromes. Bone health is essential in older cancer patient's care. Bone risk assessment should be part of CGA in routine use and specific decision-making tools should be developed. Bone event management must be integrated throughout the patient's care pathway and oncogeriatrics multidisciplinarity should include rheumatological expertise.

Implementation and evaluation of a remote geriatric assessment and intervention program in Brazil

BACKGROUND

This study sought to determine the feasibility and acceptability of a remote geriatric assessment (GA) and implementation (GAIN) program in Brazil. The authors also explored the effect of this program on health-related quality of life (HR-QOL) outcomes 3 months after initiating treatment.

METHODS

This is a longitudinal study enrolling older adults (65+ years), diagnosed with any type of solid tumor, scheduled to initiate chemotherapy in a networked Brazilian cancer center. The GA was performed through telehealth. We assessed the feasibility of the remote GA, acceptability to patients, and changes in patient-centered outcomes (HR-QOL, mood, function) from baseline to month 3. Linear mixed model analysis was done, adjusting for age, gender, race, income, and disease stage.

RESULTS

Fifty-six patients completed all intended assessments. Notably, the threshold of feasibility was 70% and there was 92% complete adherence. Average age was 76 years old (SD = 7.2). Most patients were female (57%), married (59%), and had a college degree (46%). The most common diagnoses were gastrointestinal (39%) and gynecological cancers (18%); most were diagnosed at an advance disease stage (77%). A total of 32 patients were referred to a remote appointment and 86% followed this recommendation(s). Significant improvement in Functional Assessment of Cancer Therapy - General FACT-G (mean difference, 6.04; p < .001), Geriatric Depression Scale (mean difference, -0.86; p = .008), and instrumental activities of daily living ratio (mean difference, 0.17; p < .001) were found.

CONCLUSION

Remote GAIN is feasible and acceptable to older adults with cancer receiving treatment in Brazil. The authors also found significant improvement in HR-QOL outcomes over time. Notably, this GAIN program could guide early detection of chemotherapy toxicity and improving patient-reported outcomes in low-resource environments.

Frailty and medical financial hardship among older adults with cancer in the United States

Background

Little is known about the association between frailty level and medical financial hardship among older adults with cancer. This study aims to describe the prevalence of frailty and to identify its association with medical financial hardship among older cancer survivors in the United States.

Methods

The National Health Interview Survey (NHIS; 2019-2020) was used to identify older cancer survivors (n = 3,919). Both the five-item (Fatigue, Resistance, Ambulation, Illnesses, and Low weight-for-height) FRAIL and the three-domain (Material, Psychological, and Behavioral) medical financial hardship questions were constructed based on the NHIS questionnaire. Multivariable logistic models were used to identify the frailty level associated with financial hardship and its intensity.

Results

A total of 1,583 (40.3%) older individuals with cancer were robust, 1,421 (35.9%) were pre-frail, and 915 (23.8%) were frail. Compared with robust cancer survivors in adjusted analyses, frail cancer survivors were more likely to report issues with material domain (odds ratio (OR) = 3.19, 95%CI: 2.16-4.69; p < 0.001), psychological domain (OR = 1.47, 95%CI: 1.15-1.88; p < 0.001), or behavioral domain (ORs ranged from 2.19 to 2.90, all with p < 0.050), and greater intensities of financial hardship.

Conclusion

Both pre-frail and frailty statuses are common in the elderly cancer survivor population, and frail cancer survivors are vulnerable to three-domain financial hardships as compared with robust cancer survivors. Ongoing attention to frailty highlights the healthy aging of older survivors, and efforts to targeted interventions should address geriatric vulnerabilities during cancer survivorship.

Oncogeriatric Developments

Cancer is a disease of aging and is rapidly becoming the number one cause of mortality in older people. Over their lifetime, one in two men and one in three women will develop a cancer, with half of the risk being beyond the age of seventy. Therefore, cancer is a problem frequently encountered by geriatricians. In this article, we review a few recent progresses that will be of interest to the geriatric community. First, we now have robust evidence that a comprehensive geriatric assessment and management change outcomes in older cancer patients, notably allowing decreased treatment toxicity, better treatment completion, and increased functional outcomes. In gastrointestinal cancers and breast cancer, several recent studies have addressed when treatment intensity can be decreased, and when it cannot. New treatments for acute myeloid leukemia are finally beginning to improve outcomes for older patients and such patients should be referred to oncologists for management. In prostate cancer, new imaging techniques (e.g., PSMA scan) and treatment options can allow better treatment targeting and spare some hormonal and chemotherapy toxicity. Finally, we review recent public policy efforts to address the epidemiologic wave of cancer in older patients on a global scale.

Effects of laughter yoga on health-related quality of life in cancer patients undergoing chemotherapy: a randomized clinical trial

BACKGROUND

Chemotherapy is associated with a wide range of physical and psychological side effects, so complementary and alternative therapies may be practiced as an independent treatment or combined with the standard ones to improve health-related quality of life of cancer patients. Laughter yoga has predominantly been used as a complementary therapy to enhance health and wellbeing of ordinary people and patients with chronic diseases. However, to date, few studies have evaluated the effects of this modern exercise on cancer patients undergoing chemotherapy in clinical settings, to the best of the authors' knowledge. the present study aimed to investigate the effects of Laughter Yoga on the health-related quality of life of cancer patients undergoing chemotherapy.

METHODS

This study was a two-group randomized clinical trial on 69 cancer patients undergoing chemotherapy at Reza Radiotherapy and Oncology Center, Iran in 2018. Patients were randomly divided into intervention and control groups. The intervention group received laughter yoga for four sessions at one-week intervals. Each session consists of one part and lasts for 20-30 min. Patients' health-related quality of life was assessed before and after the laughter yoga sessions using Quality of Life Questionnaire European Organization for Research and Treatment of Cancer (EORTC QLQ-C30) version 3.0. SPSS Statistics (v.20 software was used to conduct Chi-square, independent t-test, Mann-Whitney, Wilcoxon and paired t-tests analyses of the data.

RESULTS

The number of participants in intervention and control groups were 34 and 35, there was no significant difference of demographic and disease related characteristics and pre-intervention HRQOL between two groups. In the intervention group, there is significant difference between pre- and post-intervention scores (Mean ± Standard Deviation) of emotional functioning (12.99 ± 10.49), physical functioning (0.78 ± 6.08), role functioning (3.43 ± 7.97), fatigue (-8.82 ± 22.01), pain (-8.33 ± 11.78), sleep disturbance (-15.68 ± 18.77), and global health and quality of life (6.37 ± 5.04) (p < 0.05). There was no significant change in the control group. Participants reported no adverse events.

CONCLUSIONS

A structured laughter yoga intervention in a hospital setting effectively improved health-related quality of life for cancer patients undergoing chemotherapy. Benefits to many patients could be expected if this would become a part of routine care.

Checkpoint inhibitors in older patients with advanced non-small cell lung cancer

Immune checkpoint inhibitors (ICIs) have revolutionized lung cancer management improving overall survival and providing durable responses with a favorable toxicity profile. New questions have emerged regarding the efficacy and safety of immunotherapy among older adults, typically underrepresented in clinical trials. Several factors have to be taken into account in order to reduce the realistic risk of over or under-treatment of this growing subgroup of patients. In this perspective, geriatric assessment and screening tools should be implemented in clinical practice; moreover older patients' inclusion into adapted-designed clinical trials should be promoted. In this review, we discuss immunotherapy activity in advanced non-small cell lung cancer (NSCLC) older patients, the role of the comprehensive geriatric assessment, treatment toxicity and its management with a focus on future perspectives in this rapidly evolving scenario.

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.

Clinical utility of geriatric assessment tools in older patients with gastrointestinal cancer

Background

Geriatric 8 (G8) and instrumental activities of daily living (IADL) are recommended to predict overall survival (OS) or risk of serious adverse events (SAEs) in older cancer patients. However, the clinical utility is relatively unknown in older patients suffering malnutrition with gastrointestinal (GI) cancer, including gastric cancer (GC) and pancreatic cancer (PC).

Materials and methods

We retrospectively included patients aged ≥65 years with GC, PC, and colorectal cancer (CRC) who received a G8 questionnaire at first visit from April 2018 to March 2020. The associations between G8/IADL and safety or OS were assessed in patients with advanced/unresectable tumors.

Results

Of 207 patients (median age: 75 years), the median G8 score was 10.5 and normal G8 score rate was 6.8%. Both the median G8 score and normal G8 (>14) score rate numerically increased in the order of GC < PC < CRC. There was no clear association between the G8 standard cutoff value of 14 and SAEs or OS. However, OS was significantly longer in patients with G8 >11 than in those with G8 ≤11 (19.3 vs. 10.5 months, p = 0.0017). Furthermore, OS was significantly better in patients with normal IADL than in those with abnormal IADL (17.6 vs. 11.4 months, p = 0.049).

Conclusion

The G8 cutoff value of 14 would not be clinically useful in patients with GI cancer for predicting OS or SAEs; however, the cutoff value of 11 and IADL may be useful to predict OS for older patients with GI cancers including GC and PC.

Pitfalls in Oncogeriatrics

An oncogeriatric interdisciplinary activity exists only in a minority of high-income countries, and it is almost absent in those with lower incomes. Considering topics, sessions, and tracks in the main meetings and conferences of the major Oncological Societies in Europe and worldwide, the USA excluded, little attention has thus far been paid to the problem of cancer in the elderly. Again, with the exception of the USA, the major cooperative groups, for example, the EORTC in Europe, have only dedicated marginal attention to the research of cancer in the elderly. Despite major shortcomings, professionals interested in geriatric oncology have taken a number of important initiatives to highlight the benefits of this particular activity, including the organization of an international society (Société Internationale de Oncogeriatrie, or SIOG). In spite of these efforts, the authors believe that the management of cancer in the older population is still encountering several important and generalized pitfalls. The main obstacle is the grossly inadequate number of geriatricians and clinical oncologists necessary to an integrated care of the ever-expanding aging population, but other hurdles have been reported. Additionally, the prejudice of ageism can lead to missing potential resources for the development of a generalized oncogeriatric approach.

Implementation of clinical recommendations from the geriatric oncology clinic

INTRODUCTION

While evidence on the value of routine geriatric assessment (GA) in cancer care for older patients is growing, there is limited data on the geriatric oncology (GO) clinic's specific recommendations and how they are implemented. In this study, we aimed to assess and evaluate the implementation of recommendations from the GO clinic at Princess Margaret Cancer Center, Toronto, Canada, within six months of the initial visit.

MATERIALS AND METHODS

A retrospective chart review was conducted on 100 consecutive adults age 65+ visiting the GO clinic from 2018 to 2019. For each patient, we evaluated the number and type of recommendations from the GO clinic. Recommendations were grouped based on clinical judgement. Of the recorded recommendations, we measured the rate of implementation within six months of the initial visit including who implemented the recommendations and why recommendations were not implemented. Data were analyzed using descriptive statistics.

RESULTS

One hundred patients visiting the GO clinic (mean age of 80.5 years, 62% male, 52% with planned curative intent, with the genitourinary site being most common) received a median of six recommendations (range of 2-12), regardless of sex, cancer stage, cancer site, and treatment intent. Medication optimization (27%), patient education (26%), and referral to allied health (14%) were the top recommendations from the GO clinic. At six-month follow-up, 83% of all recommendations were implemented, of which 94% were performed by the GO clinic team. Patient education was implemented at a 100% rate by the GO clinic at the time of initial assessment. GO follow-up visit and other diagnostic tests (hearing test, vision test) were the recommendations with the lowest implementation rates, at 51% and 31%, respectively. The most common reasons for recommendations not being implemented were patient transfer to palliative care/death and patient declining recommendations due to busy appointment schedules.

DISCUSSION

A median of six recommendations were made per patient. The vast majority of recommendations were implemented, predominantly by the GO team. Overall, the study helps evaluate recommendations provided to patients visiting GO clinics, identify potential gaps, and assist with resource planning for optimal cancer care for older adults.

Predictors of immune checkpoint inhibitor-related adverse events in older patients with lung cancer: a prospective real-world analysis

PURPOSE

Older patients with cancer are underrepresented in pivotal trials of immune checkpoint inhibitors (ICIs). This study aimed to investigate immune-related adverse events (irAEs) that occur in older patients with lung cancer treated with ICIs, and explore predictors of the occurrence of irAEs.

METHODS

A prospective analysis was performed on older patients with lung cancer aged ≥ 65 years who were treated with anti-programmed cell death-1/-ligand 1 (PD-1/PD-L1) inhibitors in Beijing Hospital from January 2018 to December 2022. The incidence and risk factors of irAEs were estimated by the Chi-square test or Wilcoxon rank-sum tests. The predictive power of Geriatric-8 (G-8) for irAEs was tested by receiver operating characteristic (ROC) curve analysis. Lymphocyte counts were measured by flow cytometry. Cytokine levels were tested by Enzyme-linked immunosorbent assay, respectively. Kaplan-Meier method was used to calculated progression-free survival (PFS) curves, and the log-rank test was used to evaluate differences.

RESULTS

A total of 201 older patients aged ≥ 65 years with lung cancer were enrolled in this study. The most common irAEs were interstitial pneumonia, dermatological toxicity and hypothyroidism, with rates of 17.2%, 16.1% and 5.6%, respectively. ROC showed that G-8 could predict the occurrence of irAEs in patients aged 65-71 years (≥ G2 irAEs: AUC = 0.757, p < 0.001; ≥ G3 irAEs: AUC = 0.862, p < 0.001), but not for patients aged ≥ 71 years. NLR, LMR, PNI, hypertension and diabetes were associated with irAEs. Lower CD4 + T cells and B cells, and lower levels of IL-10 were associated with the development of irAEs.

CONCLUSION

Our study confirmed the accuracy of G-8 for predicting irAEs in older patients. We also identified several predictors of irAEs in older patients with lung cancer.

Skeletal muscle mass recovery after oesophagectomy and neoadjuvant chemotherapy in oesophageal cancer: retrospective cohort study

OBJECTIVE

Skeletal muscle mass (SMM) is an important biomarker for prognosis and health in older patients with cancer. Limited information is available on the recovery course of SMM after oesophagectomy following neoadjuvant chemotherapy (NAC) in older patients. This study was performed to investigate the recovery course of SMM after oesophagectomy following NAC and the preoperative predictors of delayed recovery in older patients with locally advanced oesophageal cancer (LAEC).

METHODS

This single-centre retrospective cohort study involved older (≥65 years) and non-older (<65 years) patients with LAEC who underwent oesophagectomy following NAC. The SMM index (SMI) was calculated using CT images. One-way analysis of variance and multivariate logistic regression analysis were performed.

RESULTS

In total, 110 older patients and 57 non-older patients were analysed. Loss of the SMI after NAC to 12 months postoperatively was significantly greater in older patients than in non-older patients (p<0.01). The significant preoperative predictor of delayed recovery of the SMI 12 months after surgery was loss of the SMI during NAC in older patients (per 1%: adjusted OR 1.249; 95% CI 1.131 to 1.403; p<0.001), but not in non-older patients (per 1%: OR 1.074; 95% CI 0.988 to 1.179; p=0.108).

CONCLUSIONS

There is an especially large unmet need for preventing the long-term sequelae of SMM loss in older patients with LAEC after oesophagectomy following NAC. In older patients, loss of SMM during NAC is an especially useful biomarker for prescribing postoperative rehabilitation to prevent postoperative loss of SMM.

Development and implementation of an interdisciplinary telemedicine clinic for older patients with cancer-Preliminary data

BACKGROUND

Frailty assessment is an important marker of the older adult's fitness for cancer treatment independent of age. Pretreatment geriatric assessment (GA) is associated with improved mortality and morbidity outcomes but must occur in a time sensitive manner to be useful for cancer treatment decision making. Unfortunately, time, resources and other constraints make GA difficult to perform in busy oncology clinics. We developed the Cancer and Aging Interdisciplinary Team (CAIT) clinic model to provide timely GA and treatment recommendations independent of patient's physical location.

METHODS

The interdisciplinary CAIT clinic model was developed utilizing the surge in telemedicine during the COVID-19 pandemic. The core team consists of the patient's oncologist, geriatrician, registered nurse, pharmacist, and registered dietitian. The clinic's format is flexible, and the various assessments can be asynchronous. Patients choose the service method-in person, remotely, or hybrid. Based on GA outcomes, the geriatrician provides recommendations and arrange interventions. An assessment summary including life expectancy estimates and chemotoxicity risk calculator scores is conveyed to and discussed with the treating oncologist. Physician and patient satisfaction were assessed.

RESULTS

Between May 2021 and June 2022, 50 patients from multiple physical locations were evaluated in the CAIT clinic. Sixty-eight percent was 80 years of age or older (range 67-99). All the evaluations were hybrid. The median days between receiving a referral and having the appointment was 8. GA detected multiple unidentified impairments. About half of the patients (52%) went on to receive chemotherapy (24% standard dose, 28% with dose modifications). The rest received radiation (20%), immune (12%) or hormonal (4%) therapies, 2% underwent surgery, 2% chose alternative medicine, 8% were placed under observation, and 6% enrolled in hospice care. Feedback was extremely positive.

CONCLUSIONS

The successful development of the CAIT clinic model provides strong support for the potential dissemination across services and institutions.

Management of Prostate Cancer in Older Adults

The majority of men with prostate cancer are diagnosed when they are older than 65 years; however, clinical trial participants are disproportionately younger and more fit than the real-world population treated in typical clinical practices. It is, therefore, unknown whether the optimal approach to prostate cancer treatment is the same for older men as it is for younger and/or more fit men. Short screening tools can be used to efficiently assess frailty, functional status, life expectancy, and treatment toxicity risk. These risk assessment tools allow for targeted interventions to increase a patient's reserve and improve treatment tolerance, potentially allowing more men to experience the benefit of the significant recent treatment advances in prostate cancer. Treatment plans should also take into consideration each patient's individual goals and values considered within their overall health and social context to reduce barriers to care. In this review, we will discuss evidence-based risk assessment and decision tools for older men with prostate cancer, highlight intervention strategies to improve treatment tolerance, and contextualize these tools within the current treatment landscape for prostate cancer.

Developing Sustainable Cancer and Aging Programs

Geriatric assessment (GA) has been shown to decrease toxicity from systemic therapy, improve completion of chemotherapy, and reduce hospitalizations in older adults with cancer. Given the aging of the cancer population, this has the potential to have a positive impact on the care of a large swath of patients seen. Despite endorsement by several international societies, including the American Society of Clinical Oncology, uptake of GA has been low. Lack of knowledge, time, and resources has been cited as reasons for this. Although challenges to developing and implementing a cancer and aging program vary depending on the health care context, GA is adaptable to every health care context from low- to high-resource settings, as well as those in which geriatric oncology is a well-established or just emerging field. We provide an approach for clinicians and administrators to develop, implement, and sustain aging and cancer programs in a doable and sustainable way.

Rural-urban disparities in mortality and geriatric assessment among older adults with cancer: The cancer & aging resilience evaluation (CARE) registry

INTRODUCTION

Rural-urban disparities persist in cancer mortality, despite improvement in cancer screening and treatment. Although older adults represent the majority of cancer cases and are over-represented in rural areas, few studies have explored rural-urban disparities in mortality and age-related impairments among older adults with cancer.

MATERIALS AND METHODS

We included 962 newly-diagnosed older adults (≥60 years) with cancer who underwent geriatric assessment (GA) at their first pre-chemotherapy visit to an academic medical center in the Southeastern United States. We used Rural-Urban Commuting Area (RUCA) codes to classify residence at time of diagnosis into urban and rural areas. We used one-year survival and pre-treatment frailty as outcomes. We used Cox proportional hazards regression to evaluate the association between residence and one-year mortality, and logistic regression to evaluate the association between residence and pre-treatment frailty. All tests were two-sided.

RESULTS

Median age at GA was 68.0 (interquartile rage [IQR]: 64.0, 74.0) years; most had colorectal cancer (24.3%) with advanced stage (III/IV 73.2%) disease. Overall, 11.4% resided in rural and 88.6% in urban areas. Rural areas had a higher proportion of White and less educated participants. After adjustment for age, sex, race, education, employment status, and cancer type/stage, rural residence was associated with higher hazard of one-year mortality (hazard ratio [HR] = 1.78, 95% confidence interval [CI] = 1.23, 2.57) compared to urban residence. Frailty was an effect modifier of this association (HROverall = 1.83, 95% CI = 1.27, 2.57; HRFrail = 2.05, 95% CI = 1.23, 3.41; HRNot Frail = 1.55, 95% CI = 0.90, 2.68).

DISCUSSION

Among older adults with newly diagnosed cancer, rural residence was associated with reduced one-year survival, particularly among frail older adults. The rural-urban disparities observed in the current study may be due to frailty in conjunction with disparities in social determinants of health across rural and urban areas. Future studies should focus on understanding and intervening on underlying causes of these disparities.

Validation of the Pictorial Fit-Frail Scale in a Thoracic Surgery Clinic

OBJECTIVE

Examine feasibility and construct validity of Pictorial Fit-Frail scale (PFFS) for the first time in older surgical patients.

BACKGROUND

The PFFS uses visual images to measure health state in 14 domains and has been previously validated in outpatient geriatric clinics.

METHODS

Patients ≥65 year-old who were evaluated in a multidisciplinary thoracic surgery clinic from November 2020 to May 2021 were prospectively included. Patients completed an in-person PFFS and Vulnerable Elders Survey (VES-13) during their visit, and a frailty index was calculated from the PFFS (PFFStrans). A geriatrician performed a comprehensive geriatric assessment (CGA) either in-person or virtually, from which a Frailty Index (FI-CGA) and Frailty Questionnaire (FRAIL) scale were obtained. To assess the validity of the PFFS in this population, the Spearman rank correlations (r spearman ) between PFFS trans and VES-13, FI-CGA, FRAIL were calculated.

RESULTS

All 49 patients invited to participate agreed, of which 46/49 (94%) completed the PFFS so a score could be calculated. The majority of patients (59%) underwent an in-person CGA and the reminder (41%) a virtual CGA. The cohort was mainly female (59.0%), with a median age of 77 (range: 67-90). The median PFFS trans was 0.27 (interquartile range [IQR] 0.12-0.34), PFFS was 11 (IQR 5-14), and 0.24 (IQR 0.13-0.32) for FI-CGA. We observed a strong correlation between the PFFS trans and FI-CGA (r spearman = 0.81, P < 0.001) and a moderate correlation between PFFS trans and VES-13 and FRAIL score (r spearman = 0.68 and 0.64 respectively, P < 0.001).

CONCLUSIONS

PFFS had good feasibility and construct validity among older surgical patients when compared to previously validated frailty measurements.

Management, Survival, and Costs of Pancreatic Cancer: Population-Based Observational Study in Catalonia

AIM

Few published studies comprehensively describe the characteristics of patients with pancreatic cancer and their treatment in clinical practice. This study aimed to describe the current clinical practice for treating pancreatic cancer in Catalonia, along with the associated survival and treatment costs.

METHODS

A retrospective observational cohort study in patients diagnosed with pancreatic cancer from 2014 to 2018, using data from the healthcare records of the Public Health System of Catalonia, was conducted. Treatment patterns and costs were described by age groups from 2014 to 2018, with survival reported until December 2021.

RESULTS

The proportion of patients receiving surgery with curative intent was low, especially in older patients (23% of patients <60 years and 9% of patients ≥80 years). The percentage of patients treated with drugs for unresectable disease also decreased with age (45% of patients <60 years and 8% of patients ≥80 years). Although age was associated with significant differences in survival after curative surgery, no differences attributable to age were observed in patients who received pharmacological treatment for unresectable disease. In patients under 60 years of age, the mean cost of the first year of treatment was EUR 17,730 (standard deviation [SD] 5754) in those receiving surgery and EUR 5398 (SD 9581) in those on pharmacological treatment for unresectable disease. In patients over 80, the mean costs were EUR 15,339 (SD 2634) and EUR 1845 (SD 3413), respectively.

CONCLUSIONS

Half of the patients diagnosed with pancreatic cancer did not receive specific treatment. Surgery with curative intent was associated with longer survival, but only 18% of (mostly younger) patients received this treatment. Chemotherapy was also used less frequently in patients of advanced age, though survival in treated patients was comparable across all age groups, so careful oncogeriatric assessment is advisable to ensure the most appropriate indication for eligibility in older patients. In general, earlier diagnosis and more effective pharmacological treatments are necessary to treat frail patients with high comorbidity, a common profile in older patients.

Risk Factors for Immune Checkpoint Inhibitor Immunotherapy Toxicity Among Older Adults with Cancer

OBJECTIVES

Immune checkpoint inhibitor immunotherapy (IO) is revolutionizing cancer care but can lead to significant toxicity. This study seeks to describe potential risk factors for immune-related adverse events (irAEs) specifically among older adults.

MATERIALS AND METHODS

This was a retrospective study at a single academic comprehensive cancer center based on chart review data abstracted by physicians. For patients aged ≥70 years, frequency, type, and grade of irAEs and their association with baseline patient demographics, comorbidities, mobility, and functional status were characterized using bivariate analysis. Based on those results, multivariable logistic regressions were constructed to model the association between these characteristics with any grade and grade 3 or higher irAEs.

RESULTS

Data were analyzed for 238 patients aged ≥70 years who received IO for mostly (≥90%) advanced cancer between 2011 and 2018. Thirty-nine percent of older adults experienced an irAE and 13% experienced one that was grade 3 or higher. In the multivariable analysis, depression was associated with an increased incidence of any grade irAE, while decreased life-space mobility was associated with an increased incidence of grade ≥3 irAEs.

CONCLUSION

Most characteristics of special interest among older adults, include fall risk, weight loss, cognitive limitations, and hearing loss, were not associated with irAEs in our study. However, decreased life-space mobility and depression are potential risk factors for IO toxicity among older adults with advanced cancer. Interventions designed to evaluate and mitigate modifiable risk factors for treatment-related toxicity are needed, and the results of this study may be useful for guiding those efforts.

Significance of the comprehensive geriatric assessment in the administration of chemotherapy to older adults with cancer: Recommendations by the Japanese Geriatric Oncology Guideline Committee

INTRODUCTION

The number of older patients with cancer is expected to continue to increase owing to the aging population. Recently, the usefulness of geriatric assessment (GA) conducted by multiple staff members from different medical backgrounds has been reported; however, a consensus on the effectiveness of GA has not yet been achieved.

MATERIALS AND METHODS

We, as the Japanese Geriatric Oncology Guideline Committee for elderly patients with cancer, conducted a literature search of randomized controlled trials published before August 2021 that used GA or comprehensive GA (CGA) as an intervention for patients with cancer undergoing chemotherapy. As the key outcomes for answering the clinical question, we focused on survival benefit, adverse events, and quality of life (QOL). After a systematic review of these studies, the expert panel member developed recommendations according to the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system.

RESULTS

For older patients with cancer, GA or CGA is suggested during or before chemotherapy (weakly recommended). Chemotherapy-induced adverse events were significantly reduced by GA/CGA interventions without any adverse effects on survival. Health-related QOL tended to improve with the GA/CGA interventions.

DISCUSSION

Although, in our opinion, GA/CGA does require time and resources, it poses no harm patients. Therefore, we suggest expanding the human resources and educating skills of medical providers for clinical implementation of GA/CGA.

Guidance for Treating the Older Adults with Colorectal Cancer

OPINION STATEMENT

The need for evidence-based data in the rapidly growing group of older patients is vast and more elderly-specific studies are desperately needed, for which there is clear demand from both patients and providers. Notably, many of the studies discussed in this review included unplanned subset analyses based on age and/or were not originally stratified by age; therefore, these data, particularly overall survival data, need to be interpreted with some caution as they may not be statistically valid based on the initial trial design and statistical plan. As we await data from ongoing elderly-specific trials, our recommendation for managing older patients with CRC should include geriatric screening tools (e.g., CSGA, VES-13, G8, CARG, CRASH) to help guide treatment adjustments for improved tolerability without sacrificing efficacy. For patients with a positive screen for significant geriatric concerns, a full geriatric assessment is recommended to guide treatment approach and supportive care. Prior data support the use of all approved medications for CRC in older adults who are fit; however, treatment breaks and dose attenuation with potential escalation are reasonable options for these patients. Ultimately, management decisions in the care of older adults with mCRC must be made through shared decision-making with the patient with consideration for the patient's functional status, comorbidities, goals of care, social support, as well as potential toxicities and possible effect on QoL.

Benefits and Barriers of Technology for Home Function and Mobility Assessment: Perspectives of Older Patients With Blood Cancers, Caregivers, and Clinicians

PURPOSE

Advances in digital health technology can overcome barriers to measurement of function and mobility for older adults with blood cancers, but little is known about how older adults perceive such technology for use in their homes.

METHODS

To characterize potential benefits and barriers associated with using technology for home functional assessment, we conducted three semistructured focus groups (FGs) in January 2022. Eligible patients came from the Older Adult Hematologic Malignancies Program at Dana-Farber Cancer Institute (DFCI), which includes adults 73 years and older enrolled during their initial consult with their oncologist. Eligible caregivers were 18 years and older and identified by enrolled patients as their primary caregiver. Eligible clinicians were practicing DFCI hematologic oncologists, nurse practitioners, or physician assistants with ≥2 years of clinical experience. A qualitative researcher led thematic analysis of FG transcripts to identify key themes.

RESULTS

Twenty-three participants attended the three FGs: eight patients, seven caregivers, and eight oncology clinicians. All participants valued function and mobility assessments and felt that technology could overcome barriers to their measurement. We identified three themes related to potential benefits: making it easier for oncology teams to consider function and mobility; providing standardized, objective data; and facilitating longitudinal data. We also identified four themes related to barriers to home functional assessment: concerns related to privacy and confidentiality, burden of measuring additional patient data, challenges in operating new technology, and concerns related to data improving care.

CONCLUSION

These data suggest that specific concerns raised by older patients, caregivers, and oncology clinicians must be addressed to improve acceptability and uptake of technology used to measure function and mobility in the home.

[Benefit of a Geriatric Evaluation before Operations, Interventions and Oncological Therapies]

Benefit of a Geriatric Evaluation before Operations, Interventions and Oncological Therapies Abstract: Older patients face an increased risk of complications and adverse outcomes during and after operations, interventions, and intense oncological therapies. At the same time, this patient group should not be excluded per se from potentially beneficial medical procedures based on chronological age alone. The timely identification of geriatric syndromes and increased vulnerability by means of comprehensive geriatric assessment is becoming increasingly important and is already recommended in the guidelines of professional societies of several medical disciplines. Nonetheless, the geriatric assessment should ideally be followed by proactive co-management in the sense of integrated care. The establishment of interdisciplinary and integrated care pathways for older hospital patients can contribute to significantly improved treatment outcomes. In addition to better patient-related outcomes and rising quality indicators, this approach may also offer positive health economic effects.

Clinical decision-making in older patients with cancer: a cross-sectional single-centre study to assess the impact of clinical judgement and patient preferences

OBJECTIVE

The heterogeneity in the population of older patients with cancer makes clinical decision-making difficult. We investigated the agreement between the G8 score and clinical judgment in frailty assessments, determined the impact of a life-expectancy calculator, and explored patient and caregiver preferences towards the treatment goal.

METHODS

Patients aged ≥75 years in need of new oncological treatment were prospectively enrolled between June 2020 and February 2021. Frailty was estimated by the oncologist and caregiver and compared to the G8 estimation. We examined whether the oncologist changed the fit/frail estimation based on life expectancy calculated using the ePrognosis tool. The main treatment goals, either longevity or quality of life (QoL), from the patient's and caregiver's perspective were noted and compared.

RESULTS

Forty-nine patients were included in the analysis. Comparison of the oncologist's and the caregiver's frailty estimation with the G8 assessment showed agreement and a Kappa coefficient of 58.3% (0.231) and 60% (0.255), respectively. The ePrognosis score and the odds of change in the frailty estimation by the oncologist showed no correlation. Regarding preferences, 28 (57.1%) and 17 (34.7%) patients and eighteen (47.3%) and seventeen (44.7%) caregivers chose longevity and QoL, respectively. The observed agreement and Kappa coefficient were 78.8% and 0.578.

CONCLUSION

Compared to the G8 assessment, frailty was underestimated by both oncologists and caregivers. Most of the patients chose longevity over QoL, and the preferences between the patient and the caregiver matched in the majority of cases.

Frailty assessment tools predict perioperative outcome in elderly patients with endometrial cancer better than age or BMI alone: a retrospective observational cohort study

OBJECTIVE

Five commonly used global health assessment tools have been evaluated to identify and assess the preoperative frailty status and its relationship with perioperative in-hospital complications and transfusion rates in older women with endometrial cancer (EC).

METHODS

Preoperative frailty status was examined by the G8 questionnaire, the Eastern Cooperative Oncology Group performance status, the Charlson Comorbidity Index and the American Society of Anesthesiologists Physical Status System, as well as the Lee-Schonberg prognostic index. The main outcome measures were perioperative laboratory values, intraoperative surgical parameters and immediately postoperative complications.

RESULTS

153 consecutive women ≥ 60 years with all stages of EC, who received primary elective surgery at the University Medical Center Mainz between 2008 and 2019 were classified with selected global health assessment tools according to their preoperative performance status. In contrast to conventional prognostic parameters like older age and higher BMI, increasing frailty was significantly associated with preoperative anemia and perioperative transfusions (p < 0.05). Moreover, in patients preoperatively classified as frail significantly more postoperative complications (G8 Score: frail: 20.7% vs. non-frail: 6.7%, p = 0.028; ECOG: frail: 40.9% vs. non-frail: 2.8%, p = 0.002; and CCI: frail: 25.0% vs. non-frail: 7.4%, p = 0.003) and an increased length of hospitalization were recorded. According to propensity score matching, the risk for developing postoperative complications for frail patients was approximately two-fold higher, depending on which global health assessment tool was used.

CONCLUSIONS

Preoperatively assessed frailty significantly predicts post-surgical morbidity rates in contrast to conventionally used single prognostic parameters such as age or BMI. A standardized preoperative assessment of frailty in the routine work-up might be beneficial in older cancer patients before major surgery to include these patients in a prehabilitation program with nutrition counseling and physiotherapy to adequately assess the perioperative risk.

Geriatric Oncology Cognition and Communication (Geri-Onc CC): An interactive training for healthcare professionals

INTRODUCTION

The number of older adults with cancer continues to increase. Many national and international organizations have called for the development of training opportunities for healthcare professionals (HCPs) to meet the unique needs of older adults with cancer and their families.

MATERIALS AND METHODS

We developed and implemented the Geriatric Oncology Cognition and Communication (Geri-Onc CC) training program for HCPs of all disciplines. This program included a two-day, intensive didactic and experiential training followed by six bi-monthly booster videoconference calls. We describe the format and content of this training, the preliminary results of program evaluation, as well as changes in knowledge, self-efficacy, and attitudes toward older adults pre- to post-training.

RESULTS

We describe data from the first six cohorts of HCPs who attended the training (n = 113). Participants rated the training highly favorably and reported that it met their training goals Mean = 4.8 (1-5 Scale). They also demonstrated a significant increase in their knowledge about geriatric oncology [(Pre-Mean = 6.2, standard deviation [SD] = 1.7; Post-Mean 6.8, SD = 1.6), p = 0.03] and self-efficacy in their ability to utilize the knowledge and skills they learned in the course [(Pre-Mean = 3.3, SD = 0.7; Post-Mean 4.5, SD = 0.4), p < 0.001]. There were no significant changes in attitudes toward older adults (p > 0.05), which were already very positive before the training.

DISCUSSION

There is a strong need for training in geriatric oncology. We have demonstrated that implementing this training was feasible, highly regarded, and positively impacted knowledge and self-efficacy regarding utilization of the knowledge and skills learned in the training.

Impact of Frailty on Health Care Resource Utilization and Costs of Care in Myelodysplastic Syndromes

PURPOSE

The role of frailty in affecting survival in myelodysplastic syndromes (MDS) is increasingly recognized. Despite this, a paucity of data exists on the association between frailty and other clinically meaningful outcomes including health care resource utilization and costs of care.

METHODS

We linked the Ontario subset of the prospective Canadian MDS registry (including baseline patient/disease characteristics) to population-based health system administrative databases. Baseline frailty was calculated from the 15-item MDS-specific frailty scale (FS-15). Primary outcomes were public health care utilization and 30-day standardized costs of care (2019 Canadian dollars) determined for each phase of disease (initial, continuation, and terminal phases). Negative binomial regression was used to assess the association between frailty and health care costs with Poisson regression to explore predictors of hospitalization.

RESULTS

Among 461 patients with complete FS-15 scores, 374 (81.1%) had a hospitalization with a mean length of stay of 10.6 days. Controlling for age, comorbidities, Revised International Prognostic Scoring System, and transfusion dependence, the FS-15 was independently associated with hospitalization during the initial (P = .02) and continuation (P = .01) phases but not the terminal disease phase (P = .09). The mean 30-day standardized cost per patient was $8,499 (median, $6,295; interquartile range, $2,798-$11,996), largely driven by cancer clinic visits and hospitalization. On multivariable analysis, the FS-15 was independently associated with costs of care during the initial disease phase (P = .02).

CONCLUSION

We demonstrate an association between frailty and clinically meaningful outcomes including hospitalization and costs of care in patients with MDS. Our results suggest that baseline frailty may help to inform patients and physicians of expected outcomes.

The GIANT trial (ECOG-ACRIN EA2186) methods paper: A randomized phase II study of gemcitabine and nab-paclitaxel compared with 5-fluorouracil, leucovorin, and liposomal irinotecan in older patients with treatment-naïve metastatic pancreatic cancer - defining a new treatment option for older vulnerable patients

INTRODUCTION

Pancreatic cancer is the fourth leading cause of cancer-related death in the US with an increasing incidence in older adults (OA) over age 70. There are currently no treatment guidelines for OA with metastatic pancreatic cancer (mPCA) and selecting a chemotherapy regimen for these patients is subjective, based largely on chronologic age and performance status (PS). Geriatric screening tools provide a more objective and accurate evaluation of a patient's overall health but have not yet been validated in patient selection for mPCA treatment. This study aims to elucidate the optimal chemotherapy treatment of vulnerable OA with mPCA and understand the geriatric factors that affect outcomes in this population.

METHODS/DESIGN

The GIANT (ECOG-ACRIN EA2186) study is multicenter, randomized phase II trial enrolling patients over age 70 with newly diagnosed mPCA. This study utilizes a screening geriatric assessment (GA) which characterizes patients as fit, vulnerable, or frail. Patients with mild abnormalities in functional status and/or cognition, moderate comorbidities, or over age 80 are considered vulnerable. Enrolled patients are randomized to one of two dose-reduced treatment regimens (gemcitabine/nab-paclitaxel every other week, or dose-reduced 5-fluoruracil (5FU)/ liposomal irinotecan (nal-IRI) every other week). GA and quality of life (QoL) evaluations are completed prior to treatment initiation and at each disease evaluation. Overall survival (OS) is the primary endpoint, with secondary endpoints including progression free survival (PFS) and objective response rate (ORR). Enrolled patients will be stratified by age (70-74 vs ≥75) and ECOG PS (0-1 vs 2). Additional endpoints of interest for OA include evaluation of risk factors identified through GA, QoL evaluation, and toxicities of interest for older adults. Correlative studies include assessment of pro-inflammatory biomarkers of aging in the blood (IL-6, CRP) and imaging evaluation of sarcopenia as predictors of treatment tolerance.

DISCUSSION

The GIANT study is the first randomized, prospective national trial evaluating vulnerable OA with mPCA aimed at developing a tailored treatment approach for this patient population. This trial has the potential to establish a new way of objectively selecting vulnerable OA with mPCA for modified treatment and to establish a new standard of care in this growing patient population.

Treatment Patterns and Outcomes of Patients with Grade 4 Glioma Treated with Radiation during the COVID-19 Pandemic

During the first year of the COVID-19 pandemic there was a global disruption in the provision of healthcare. Grade 4 gliomas are rapidly progressive tumors, and these patients are at risk of poorer outcomes due to delays in diagnosis or treatment. We retrospectively evaluated the impact of the pandemic on treatment patterns and outcomes of patients with grade 4 gliomas in British Columbia. We identified a cohort of 85 patients treated with radiotherapy between March 2020–2021 (COVID era) and compared baseline characteristics, treatments, and outcomes with a control cohort of 79 patients treated between March 2018–2019 (pre-COVID era). There were fewer patients treated with radiotherapy over age 65 in the COVID era compared to the pre-COVID era (p = 0.037). Significantly more patients were managed with biopsy relative to partial or gross total resection during the COVID era compared to the pre-COVID era (p = 0.04), but there were no other significant differences in time to assessment, time to treatment, or administration of adjuvant therapy. There was no difference in overall survival between eras (p = 0.189). In this assessment of outcomes of grade 4 gliomas during the pandemic, we found that despite less aggressive surgical intervention during the COVID era, outcomes were similar between eras.

Non-intensive acute myeloid leukemia therapies for older patients

INTRODUCTION

Acute myeloid leukemia (AML) is an aggressive disease predominantly affecting the elderly population. The elderly population represents a challenging group to treat and the prognosis is generally poor with significantly worse treatment outcomes compared to the younger population. While the goal of treatment for younger fit patients is cure and includes intensive chemotherapy and stem cell transplantation, these strategies are not always feasible for elderly unfit patients due to increased frailty, co-morbidities, and, subsequently, an increased risk of treatment-related toxicity and mortality.

AREAS COVERED

This review will discuss both patient- and disease-related factors, outline prognostication models and summarize current treatment options, including intensive and less intensive treatment strategies and novel agents.

EXPERT OPINION

Although recent years have seen major advances in the development of low-intensity therapies, there is still a lack of consensus on the optimal treatment for this patient group. Because of the heterogeneity of the disease, personalizing the treatment strategy is important and curative-oriented approaches should be selected wisely, rather than following a rigid hierarchical algorithm.

An Unsupervised Machine Learning Approach to Evaluating the Association of Symptom Clusters With Adverse Outcomes Among Older Adults With Advanced Cancer: A Secondary Analysis of a Randomized Clinical Trial

Importance

Older adults with advanced cancer who have high pretreatment symptom severity often experience adverse events during cancer treatments. Unsupervised machine learning may help stratify patients into different risk groups.

Objective

To evaluate whether clusters identified from baseline patient-reported symptom severity were associated with adverse outcomes.

Design, Setting, and Participants

This secondary analysis of the Geriatric Assessment Intervention for Reducing Toxicity in Older Patients With Advanced Cancer (GAP70+) Trial (2014-2019) included patients who completed the National Cancer Institute Patient-Reported Outcomes version of the Common Terminology Criteria for Adverse Events (PRO-CTCAE) before starting a new cancer treatment regimen and received care at community oncology sites across the United States. An unsupervised machine learning algorithm (k-means with Euclidean distance) clustered patients based on similarities of baseline symptom severities. Clustering variables included severity items of 24 PRO-CTCAE symptoms (range, 0-4; corresponding to none, mild, moderate, severe, and very severe). Total severity score was calculated as the sum of 24 items (range, 0-96). Whether the clusters were associated with unplanned hospitalization, death, and toxic effects was then examined. Analyses were conducted in January and February 2022.

Exposures

Symptom severity.

Main Outcomes and Measures

Unplanned hospitalization over 3 months (primary), all-cause mortality over 1 year, and any clinician-rated grade 3 to 5 toxic effect over 3 months.

Results

Of 718 enrolled patients, 706 completed baseline PRO-CTCAE and were included (mean [SD] age, 77.2 [5.5] years, 401 [56.8%] male patients; 51 [7.2%] Black and 619 [87.8%] non-Hispanic White patients; 245 [34.7%] with gastrointestinal cancer; 175 [24.8%] with lung cancer; mean [SD] impaired Geriatric Assessment domains, 4.5 [1.6]). The algorithm classified 310 (43.9%), 295 (41.8%), and 101 (14.3%) into low-, medium-, and high-severity clusters (within-cluster mean [SD] severity scores: low, 6.3 [3.4]; moderate, 16.6 [4.3]; high, 29.8 [7.8]; P < .001). Controlling for sociodemographic variables, clinical factors, study group, and practice site, compared with patients in the low-severity cluster, those in the moderate-severity cluster were more likely to experience hospitalization (risk ratio, 1.36; 95% CI, 1.01-1.84; P = .046). Moderate- and high-severity clusters were associated with a higher risk of death (moderate: hazard ratio, 1.31; 95% CI, 1.01-1.69; P = .04; high: hazard ratio, 2.00; 95% CI, 1.43-2.78; P < .001), but not toxic effects.

Conclusions and Relevance

In this study, unsupervised machine learning partitioned patients into distinct symptom severity clusters; patients with higher pretreatment severity were more likely to experience hospitalization and death.

Trends in survival for cancer patients aged 65 years or over from 1995 to 2014 in the United States: A population-based study

BACKGROUND

Adults aged 65 years and above account for over half of all cancer diagnoses in the United States, but little is known about trend of elderly cancer survival in the United States. We aimed to assess the survival trend for elderly cancer in the United States from 1995 to 2014.

METHODS

We used data from Surveillance, Epidemiology, and End Results 12 registries and included 1,112,441 eligible patients aged 65 years or older who were diagnosed between 1995 and 2014 with cancer and followed up until December 2019. Overall and stage-specific 5-year relative survival, ratio of observed survival to expected survival, with 95% confidence intervals (CIs) of elderly cancer patients stratified by age were estimated during four periods (1995-1999, 2000-2004, 2005-2009, and 2010-2014). Cox proportional hazards models were used to estimate hazard ratios for cancer-specific death among patients diagnosed during 2000-2004, 2005-2009, 2010-2014, compared diagnoses in 1995-1999. We also calculated stage distribution and treatment rate during four periods.

RESULTS

In the United States, 5-year relative survival for elderly cancer patients improved from 57.3% (95% CIs 57.0-57.5) in 1995-1999 to 60.7% (60.5-60.9) in 2010-2014. After controlling for sociodemographic and tumor characteristics, about a 19% reduction in cancer-specific deaths among diagnoses in 2010-2014 compared with 1995-1999. Cancer survival improved for elderly patients in all age groups, with exception of stable survival for patients aged 85 and above. Comparing 1995-1999 with 2010-2014, relative survival improved from 84.7% (84.3-85.1) to 86.7% (86.3-87.0) for localized stage and from 12.4% (12.1-12.7) to 18.7% (18.4-19.0) for distant stage for all cancers combined. The trends in stage distribution and treatment rate for all cancers combined were relatively stable.

CONCLUSIONS

In the United States, survival for elderly cancer patients has improved slightly from 1995 to 2014, possibly mainly due to advances in treatment. Further studies are warranted to explore interventions to improve elderly cancer survival.

Geriatric assessment and treatment decision-making in surgical oncology

PURPOSE OF REVIEW

Present an approach for surgical decision-making in cancer that incorporates geriatric assessment by building upon the common categories of tumor, technical, and patient factors to enable dual assessment of disease and geriatric factors.

RECENT FINDINGS

Conventional preoperative assessment is insufficient for older adults missing important modifiable deficits, and inaccurately estimating treatment intolerance, complications, functional impairment and disability, and death. Including geriatric-focused assessment into routine perioperative care facilitates improved communications between clinicians and patients and among interdisciplinary teams. In addition, it facilitates the detection of geriatric-specific deficits that are amenable to treatment. We propose a framework for embedding geriatric assessment into surgical oncology practice to allow more accurate risk stratification, identify and manage geriatric deficits, support decision-making, and plan proactively for both cancer-directed and non-cancer-directed therapies. This patient-centered approach can reduce adverse outcomes such as functional decline, delirium, prolonged hospitalization, discharge to long-term care, immediate postoperative complications, and death.

SUMMARY

Geriatric assessment and management has substantial benefits over conventional preoperative assessment alone. This article highlights these advantages and outlines a feasible strategy to incorporate both disease-based and geriatric-specific assessment and treatment when caring for older surgical patients with cancer.
