Models of Care in Geriatric Oncology

Tailoring Therapy in Older Adults With Hematologic Malignancies

Hematologic malignancies most often present in the sixth or seventh decade of life. Even so, many older adults may be unable to tolerate standard chemotherapy or require supplementary care or dose adjustments to do so. Both in community and academic centers, geriatric assessment (GA) can be used to improve the care of older adults with blood cancers. For example, hematologic oncologists can use GA to guide treatment selection, adjusting for patient frailty and goals, as well as prompt initiation of enhanced supportive care. After initial therapy, GA can improve the identification of older adults with aggressive myeloid malignancies who would benefit from hematopoietic cell transplantation (HCT), inform shared decision making, as well as allow transplanters to tailor conditioning regimen, donor selection, graft-versus-host disease prophylaxis, and pre- and post-HCT treatments. As in HCT, GA can improve the care of older patients with relapsed lymphoma or multiple myeloma eligible for chimeric antigen receptor-T therapy, identifying patients at higher risk for toxicity and providing a baseline for subsequent neurocognitive testing. Here, we review the data supporting GA for the care of older adults with blood cancers, from the community to the academic center. In addition, we explore future directions to optimize outcomes for older adults with hematologic malignancies.

Real world efficacy and toxicity of consolidation durvalumab following chemoradiotherapy in older Australian patients with unresectable stage III non-small cell lung cancer

INTRODUCTION

Consolidation durvalumab following platinum-based chemoradiotherapy (CRT) significantly improved overall survival for patients with unresectable stage III non-small cell lung cancer (NSCLC) in the PACIFIC trial. However, older patients were underrepresented in PACIFIC, and subsequent analyses suggested trends toward poorer survival and increased toxicity in patients aged ≥70 years old. We assessed the effectiveness and safety of consolidation durvalumab following CRT in older Australian patients with unresectable stage III NSCLC.

MATERIALS AND METHODS

This retrospective observational study was conducted across seven sites in Sydney, Australia between January 2018 and September 2021. All adult patients with unresectable stage III NSCLC who received platinum-based chemoradiotherapy followed by at least one cycle of consolidation durvalumab were included. Older patients were defined as being ≥70 years old.

RESULTS

Of 152 patients included in the analysis, 42.8% (n = 67) patients were 70 years or older. Median follow-up was 26.1 months. The two-year overall survival and median PFS was similar between older and younger patients. At two years, 74.8% (95% confidence interval [CI]: 65.4-84.2%) of patients <70 years old and 65.2% (95% CI: 53.4-77.0%) of older patients were alive (p = 0.07; hazard ratio [HR] 1.64, 95% CI: 0.95-2.81). Median progression-free survival (PFS) in patients <70 years was 30.3 months (95% CI: 22.2-38.4 months) compared with 26.7 months (95% CI: 12.8-40.6 months) in older patients (p = 0.22; HR 1.46, 95% CI: 0.80-2.65). Toxicity was also similar, with 11.5% of patients <70 years old and 18.5% of older patients experiencing grade 3-4 adverse events (AEs; p = 0.23); 16.1% and 24.6% of the patients, respectively, discontinued treatment due to toxicity (p = 0.19). Grade 3-4 AEs and treatment discontinuation were associated with Charlson Comorbidity Index >5 (p = 0.011) and chronic obstructive pulmonary disease diagnosis at presentation (p = 0.002), respectively.

DISCUSSION

Older Australian patients receiving consolidation durvalumab following CRT experienced comparable outcomes to their younger peers. Comorbidity burden may be more important determinants of treatment tolerance than chronological age.

Implementation of a geriatric oncology service at the Royal Marsden Hospital

INTRODUCTION

Despite significant evidence supporting the benefits of comprehensive oncogeriatric assessment in the management of older patients with cancer, the adoption of specialised geriatric oncology programs in the United Kingdom remains limited. Descriptions of clinic structure and models, patient demographics and baseline characteristics, resource utilisation, and predictors of resource utilisation are lacking in this population, which may complicate or impede the planning, resourcing, and development of further services in this subspecialty on a national and regional basis.

MATERIALS AND METHODS

Between November 2021 and April 2023, 244 patients commencing systemic anticancer treatment at the Royal Marsden Hospital, London underwent geriatric screening using the Senior Adult Oncology Programme-3 (SAOP3) screening tool. Baseline clinical factors (sex, age, Charlson Comorbidity Index score, Cumulative Illness Rating Scale-Geriatric [CIRS-G] score, Katz Index score, Barthel Index score, treatment intent, and Eastern Cooperative Oncology Group Performance Status [ECOG-PS]) were assessed as predictors of geriatric impairments and need for multidisciplinary referral and intervention using a negative binomial regression analysis. Referral rates to multidisciplinary teams were assessed against ECOG-PS score using point-biserial correlation, as well as against a historical control using descriptive statistics.

RESULTS

The median age of participants was 77; 75.8% were female. Breast cancer was the most prevalent diagnosis (61.9%). Most patients (67.6%) were undergoing treatment in the palliative setting. Two hundred eleven (86.5%) patients were identified as having at least one geriatric impairment. Six hundred forty-nine multidisciplinary referrals were made, of which 583 (86.7%) were accepted by the referred patient. Higher ECOG PS was positively associated with geriatric impairments in physiotherapy, occupational therapy, dietetics, pharmacy, and welfare rights domains, as well as with the overall number of geriatric impairments.

DISCUSSION

The Royal Marsden Senior Adult Oncology Programme represents the first geriatric oncology service in a tertiary cancer centre in the United Kingdom. Following implementation of SAOP3 screening, we observed a substantial increase in referrals to all multidisciplinary teams, suggestive of previously underrecognized needs among this population. The need for multidisciplinary intervention was strongly correlated with baseline ECOG-PS score, but not with other measured clinical variables, including comorbidity or functional indices.

Caring for older adults with cancer in Canada: Views from healthcare providers and cancer care allies in the community

BACKGROUND

Cancer is common and disproportionately impacts older adults. Moreover, cancer care of older adults is complex, and the current Canadian cancer care system struggles to address all of the dimensions. In this project, our goal was to understand the barriers and facilitators to caring for older adults with cancer from perspectives of healthcare professionals and cancer care allies, which included community groups, seniors' centers, and other community-based supports.

METHODS

In collaboration with a patient advisory board, we conducted focus groups and interviews with multiple local healthcare professionals and cancer care allies in British Columbia, Canada. We used a descriptive qualitative approach and conducted a thematic analysis using NVivo software.

RESULTS

A total of 71 participants of various disciplines and cancer care allies participated. They identified both individual and system-level barriers. Priority system-level barriers for older adults included space and staffing constraints and disconnections within healthcare systems, and between healthcare practitioners and cancer care allies. Individual-level barriers relate to the complex health states of older adults, caregiver/support person needs, and the needs of an increasingly diverse population where English may not be a first or preferable language.

CONCLUSIONS

This study identified key barriers and facilitators that demonstrate aligned priorities among a diverse group of healthcare practitioners and cancer care allies. In conjunction with perspectives from patients and caregivers, these findings will inform future improvements in cancer care. Namely, we emphasize the importance of connections among health systems and community networks, given the outpatient nature of cancer care and the needs of older adults.

Changes in the Epidemiologic Pattern of Primary CNS Tumors in Response to the Aging Population: An Updated Nationwide Cancer Registry Data in the Republic of Korea

PURPOSE

Primary CNS tumors (PCNSTs) are tumors originating from the brain and surrounding tissues. These tumors account for a significant proportion of cancer deaths and morbidity globally. Accurate epidemiologic data are essential for shaping clinical practices, research priorities, and health care policies. This study presents the latest 2020 national data on PCNSTs from the Republic of Korea (ROK) and explores the trends in incidence and their societal implications in the context of an aging population.

METHODS

This is a cross-sectional, observational study conducted using data sourced from the Korea National Cancer Incidence Database by the Korea Central Cancer Registry. The study analyzed national data on PCNSTs in the ROK for the years 2010, 2013, 2016, and 2020.

RESULTS

In 2020, 15,568 new PCNST cases were diagnosed in the ROK. The overall crude rate was 30.32, and the age-standardized rate was 19.37 per 100,000 persons. A decade-long trend analysis revealed an increasing trend in newly diagnosed glioblastoma and lymphoma, and a decreasing trend in embryonal tumors, in relation to the aging population of the ROK.

CONCLUSION

This study shows the significant impact of demographic shifts on the epidemiologic patterns of PCNSTs in the ROK. Our findings emphasize the need for collaborative efforts to address the rising challenges posed by the changing incidence of PCNSTs related to an aging population.

Implementation of a nurse-led, multidisciplinary model of care for older adults with cancer: a process evaluation protocol

INTRODUCTION

Cancer is predominantly a disease of older adults, with an increasing number of cancer diagnoses in individuals aged 65 or older. Multiple geriatric factors have been shown to impact patient outcomes in cancer treatment. However, oncology specialists are not well adapted to incorporate geriatric assessment into practice due to a lack of resources and knowledge of the specialty.The primary aim of this study is to implement and evaluate a nurse-led, multidisciplinary model of care for older adults with cancer at two public tertiary hospitals in Melbourne, Australia.

METHODS AND ANALYSIS

This study will aim to assess 200 patients across 2 sites. Both sites will assess individuals with lung cancer; the second site will also include individuals with genitourinary, upper gastrointestinal and colorectal cancers.This process evaluation will use quantitative and qualitative methods to explore the reach, effectiveness, adoption, implementation, and maintenance (RE-AIM) of the nurse-led, multidisciplinary model of care.

ETHICS AND DISSEMINATION

Ethical approval and local governance approvals have been obtained by Austin Health and Monash Health Human Research Ethics committees. Dissemination will occur via publications, conferences, social medical and local engagement with clinicians, consumers and managers.

How old is too old? Frailty and geriatric assessments of older patients undergoing allogeneic HCT

Allogeneic hematopoietic cell transplantation (HCT) is a curative-intent treatment for many hematologic malignancies but carries a significant risk of morbidity and mortality. An increasing number of older adults are receiving HCT, but current pretransplant evaluations overlook the unique vulnerabilities that older adults face. Oncology-specific geriatric and frailty assessments provide a comprehensive evaluation of older adults, help better weigh the risks of HCT with patients, and guide personalized optimization strategies to minimize vulnerabilities. Geriatric assessments evaluate seven domains: comorbidities, physical function, mental health, cognition, nutrition, medications, and social support. Frailty indices provide unique evaluations into a patient's overall status. Various standardized measures have been used to evaluate these areas in older adults prior to HCT. Different care models exist for the integration of geriatrics and geriatric principles into HCT evaluation: a multidisciplinary consultative clinic, a geriatrician alongside the HCT clinic, or a primary geriatric hematologist/transplant physician. Future studies are needed to investigate the use of geriatric assessments in selecting the conditioning regimen and intensity and measuring the impact of geriatric assessment-driven interventions on quality of life and toxicities post transplant.

The Five "Ws" of Frailty Assessment and Chronic Lymphocytic Leukemia: Who, What, Where, Why, and When

Chronic lymphocytic leukemia (CLL) is a disease of the elderly, but chronological age does not accurately discriminate frailty status at the inter-individual level. Frailty describes a person's overall resilience. Since CLL is a stressful situation, it is relevant to assess the patient´s degree of frailty, especially before starting antineoplastic treatment. We are in the era of targeted therapies, which have helped to control the disease more effectively and avoid the toxicity of chemo (immuno) therapy. However, these drugs are not free of side effects and other aspects arise that should not be neglected, such as interactions, previous comorbidities, or adherence to treatment, since most of these medications are taken continuously. The challenge we face is to balance the risk of toxicity and efficacy in a personalized way and without forgetting that the most frequent cause of death in CLL is related to the disease. For this purpose, comprehensive geriatric assessment (GA) provides us with the opportunity to evaluate multiple domains that may affect tolerance to treatment and that could be improved with appropriate interventions. In this review, we will analyze the state of the art of GA in CLL through the five Ws.

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.

A Retrospective Study Investigating the Safety and Efficacy of Nanoliposomal Irinotecan in Elderly Patients with Unresectable Pancreatic Cancer

Although nanoliposomal irinotecan combined with 5-fluorouracil and leucovorin (nal-IRI+5-FU/LV) has been used to treat first-line resistant unresectable pancreatic cancer, the efficacy and safety data among the elderly remain limited. We retrospectively analyzed clinical outcomes among elderly patients. Patients treated with nal-IRI+5-FU/LV were assigned to the elderly (≥75 years) and non-elderly (<75 years) groups. Herein, 85 patients received nal-IRI+5-FU/LV, with 32 assigned to the elderly group. Patient characteristics in the elderly and non-elderly groups were as follows: age: 78.5 (75-88)/71 (48-74), male: 17/32 (53%/60%), performance status (ECOG) 0:9/20 (28%/38%), nal-IRI+5-FU/LV in second line: 23/24 (72%/45%), respectively. A significantly high number of elderly patients exhibited aggravated kidney and hepatic functions. Median overall survival (OS) and progression-free survival (PFS) in the elderly group vs. non-elderly group were 9.4 months vs. 9.9 months (hazard ratio (HR) 1.51, 95% confidence interval (CI) 0.85-2.67, p = 0.16) and 3.4 months vs. 3.7 months (HR 1.41, 95% CI 0.86-2.32, p = 0.17). Both groups exhibited a similar incidence of efficacy and adverse events. There were no significant differences in OS and PFS between groups. We analyzed the C-reactive protein/albumin ratio (CAR) and neutrophil/lymphocyte ratio (NLR) as indicators that could determine eligibility for nal-IRI+5-FU/LV. The median CAR and NLR scores in the ineligible group were 1.17 and 4.23 (p < 0.001 and p = 0.018, respectively). Elderly patients with worse CAR and NLR score could be deemed ineligible for nal-IRI+5-FU/LV.

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.

Feasibility of a Geriatric Oncology Longitudinal End to End (GOLDEN) Program in a Tertiary Cancer Center in Singapore

INTRODUCTION

In the National University Cancer Institute, Singapore (NCIS), 2 pilot programs providing (i) surgical prehabilitation before cancer surgery and (ii) geriatric oncology support for older adults planned for chemotherapy and/or radiotherapy were merged to form the Geriatric Oncology Longitudinal End to eNd (GOLDEN) program in 2019 to support patients from the time of their cancer diagnosis, through their treatment process, to cancer survivorship.

METHODS AND MATERIALS

Older adults aged ≥65 years were enrolled in either surgical prehabilitation, the geriatric medical oncology (GO) arm, or both. All patients undergo a geriatric assessment. We assessed if patients had a change in treatment plans based on GOLDEN recommendations, and the impact on patient related outcomes.

RESULTS

There were 777 patients enrolled in the GOLDEN program over 2 years; 569 (73%) were enrolled in surgical prehabilitation, 308 (40%) were enrolled in the GO arm, with 100 (12.8%) enrolled in both. 56.9% were females. Median age was 73. Lower gastrointestinal (51.2%) and hepatobiliary cancers (24.1%) were the most common cancer types. 43.4% were pre-frail and 11.7% were frail. Of the 308 patients in the GO arm, 86.0% had geriatric syndromes, while 60.7% had a change in their treatment plans based on GOLDEN recommendations. 31.5% reported an improved global health status, while 38.3% maintained their global health status. 226 (73%) responded that they had benefited from the GOLDEN.

CONCLUSION

More than half of the population was either pre-frail or frail. Amongst those in the GO arm, the majority had geriatric syndromes and had a change in their treatment plans based on GOLDEN recommendations. Majority reported either improvement or maintenance in global health status, with most feeling they have benefited from the program. Further evaluation of the longitudinal geriatric hematology-oncology program for cancer-related outcomes and sustainability should be carried out.

Geriatric Oncology in Portugal: Where We Are and What Comes Next—A Survey of Healthcare Professionals

In keeping with the trend worldwide, in Portugal, more than 60% of newly diagnosed patients with cancer are aged 65 years or older, which makes older adults the most common population seen in an oncology practice. This study’s objectives were to assess geriatric oncology practices in Portugal and investigate medical professionals’ current needs and perceptions on the treatment of elderly cancer patients. Methods: A cross-sectional study was conducted using a web-based survey of healthcare providers treating elderly patients. Results: There were 222 responses: 62.6% of physicians reported the absence of geriatric oncology and/or geriatrics consultations in their institutions, 14.9% had guidelines for the management of older patients with cancer and 4.5% had physicians dedicated to geriatric oncology. The reported use of geriatric assessment tools was 23.4%. Medical oncologists and physicians from medical specialties (p = 0.009) and those practicing in the south of Portugal (p = 0.054) were more likely to use geriatric assessment. Education and training in geriatric oncology was identified by 95.0% of respondents as an unmet need. The inquiries identified that geriatric assessment could be useful to define a therapeutic strategy (85.1%), detect frailty (77.5%), predict toxicity and improve quality of life (73.4%). Conclusions: There is a paucity of expertise and training in geriatric oncology in Portugal but an increasing perception of the value of geriatric assessment and the demand for education. In the next years, Portugal will progress in this area with the aid of the recently created Geriatric Oncology Working Group.

Addressing the Needs of Older Adults With Cancer in Low- and Middle-Income Settings

The number of older adults in the world is projected to increase steeply over the next 30 years; most older adults will live in low- and middle-income countries. This will have a direct impact on the global cancer burden, as cancer is largely a disease of aging. A revolution in the way we care for older adults in low- and middle-income settings is needed to meet rapidly rising demands. Regardless of a nation's relative wealth or resources, implementing the geriatric assessment in cancer care has presented a challenge because of omission of the principles of geriatric oncology from formal training and continuing education, lack of time, and a shortage of qualified personnel. To meet the challenge of caring for older adults globally, we must: (1) re-imagine aging-focused training for providers and nurses, (2) create and strengthen collaborations/partnerships between geriatric oncology teams and aging-service organizations, and (3) increase advocacy for age-friendly health care policy. By harnessing technology, the reach of specialized oncology education and care can be extended even-or especially-to low- and middle-income settings.
