Treating acute myelogenous leukemia in patients aged 70 and above: Recommendations from the International Society of Geriatric Oncology (SIOG).

Acute myeloid leukemia (AML) treatment is challenging in older patients. There is a lack of evidence-based recommendations for older patients ≥70, a group largely underrepresented in clinical trials. With new treatment options being available in recent years, recommendations are needed for these patients. As such the International Society of Geriatric Oncology (SIOG) assembled a task force to review the evidence specific to treatment and outcomes in this population of patients ≥70 years. Six questions were selected by the expert panel in domains of (1) baseline assessment, (2) frontline therapy, (3) post-remission therapy, (4) treatment for relapse, (5) targeted therapies, and (6) patient reported outcome/function and enhancing treatment tolerance. Information from current literature was extracted, combining evidence from systematic reviews/meta-analyses, decision models, individual trials targeting these patients, and subgroup data. Accordingly, recommendations were generated using a GRADE approach upon reviewing current evidence by consensus of the whole panel. It is our firm recommendation and hope that direct evidence should be generated for patients aged ≥70 as a distinct group in high need of improvement of their survival outcomes. Such studies should integrate information from a geriatric assessment to optimize external validity and outcomes.

Exercise and epigenetic ages in older adults with myeloid malignancies.

BACKGROUND: Older adults with myeloid malignancies are susceptible to treatment-related toxicities. Accelerated DNAm age, or the difference between DNA methylation (DNAm) age and chronological age, may be used as a biomarker of biological age to predict individuals at risk. In addition, cancer treatment can also lead to accelerated DNAm age. Exercise is a promising intervention to reduce or prevent functional, psychological, and cognitive impairments in older patients with myeloid malignancies, yet there is little evidence of the effects of exercise on DNAm age. We explored (1) the associations of accelerated DNAm age with physical, psychological, and cognitive functions at baseline; (2) changes in DNAm age from baseline to post-intervention; and (3) the associations of changes in accelerated DNAm age with changes in functions from baseline to post-intervention. METHODS: We enrolled older patients with myeloid malignancies to a single-arm pilot study testing a mobile health (mHealth) exercise intervention that combines an exercise program (EXCAP©®) with a mobile application over 2 cycles of chemotherapy (8-12 weeks). Patients completed measures of physical, psychological, and cognitive functions and provided blood samples for analyses of DNAm age at baseline and post-intervention. Paired t-tests or Wilcoxon signed rank tests assessed changes in DNAm ages, and Spearman's correlation assessed the relationships between accelerated ages and functions. RESULTS: We included 20 patients (mean age: 72 years, range 62-80). Accelerated GrimAge, accelerated PhenoAge, and DunedinPACE were stable from baseline to post-intervention. At baseline, DunedinPACE was correlated with worse grip strength (r = -0.41, p = 0.08). From baseline to post-intervention, decreases in accelerated GrimAge (r = -0.50, p = 0.02), accelerated PhenoAge (r = - 0.39, p = 0.09), and DunedinPace (r = - 0.43, p = 0.06) were correlated with increases in distance walked on 6-min walk test. Decreases in accelerated GrimAge (r = - 0.49, p = 0.03), accelerated PhenoAge (r = - 0.40, p = 0.08), and DunedinPace (r = - 0.41, p = 0.07) were correlated with increases in in grip strength. CONCLUSIONS: Among older adults with myeloid malignancies receiving chemotherapy, GrimAge and PhenoAge on average are stable after a mHealth exercise intervention. Decreases in accelerated GrimAge, accelerated PhenoAge, and DunedinPACE over 8-12 weeks of exercise were correlated with increased physical performance. Future trials assessing the effects of exercise on treatment-related toxicities should evaluate DNAm age. Trial registration Clinicaltrials.gov identifier: NCT04981821.

Older patients' experiences following initial diagnosis of acute myeloid leukemia: A qualitative study.

INTRODUCTION: The onset of symptoms and the diagnosis of acute myeloid leukemia (AML) often occur suddenly and may lead to a range of emotional responses. Understanding patients' experiences and emotional states allows clinicians to tailor care to patients' needs. Previous studies have largely focused on patients' experiences at diagnosis and after remission has been achieved among those who received intensive chemotherapy. In this study, we evaluated experiences of older patients with AML who had received or were receiving treatments of varying intensity, in both outpatient and inpatient settings, and who were at different stages in their treatment course at the time of our interviews. MATERIALS AND METHODS: We conducted a single center qualitative study which aimed to understand factors influencing older patients' treatment decision-making and the findings were previously reported. This analysis specifically explored older patients' experiences at various stages after AML diagnosis. We purposively sampled patients based on treatment intensity and stage of treatment (undergoing induction treatment, post-remission treatment, or post-allogeneic hematopoietic stem cell transplant). We recruited fifteen patients aged ≥60 years with AML. The sample size was determined based on reaching data saturation for the primary study aim. For this analysis, data saturation was reached by the fourteenth manuscript. In-depth semi-structured interviews that had been recorded and transcribed were re-analyzed using inductive thematic analysis to explore patients' experiences. Coding was performed using Atlas.ti. We identified themes with the aim of capturing the most commonly shared experiences. RESULTS: Mean age of the fifteen patients was 72.1 years; all had received one or more treatments including intensive induction therapy (10/15), lower-intensity treatment (7/15), and/or hematopoietic stem cell transplant (3/15). Patients experienced strong negative emotional responses, including shock, that were barriers to processing information and meaningful communication. Patients also shared their perspectives on communication with healthcare professionals (including thoughts on adequacy of information provided) and coping strategies. DISCUSSION: Understanding older patients' experiences, including emotional responses and barriers to communication and decision making, at AML diagnosis and throughout the illness trajectory allows clinicians to address patients' supportive care needs during this difficult period.

How Genetics Can Drive Initial Therapy Choices for Older Patients with Acute Myeloid Leukemia.

OPINION STATEMENT: Treatment of older adults with acute myeloid leukemia (AML) is challenging. Therapy decisions must be guided by multiple factors including aging-related conditions (e.g., comorbidities, functional impairment), therapy benefits and risks, patient preferences, and disease characteristics. Balancing these factors requires understanding the unique, and frequently higher-risk cytogenetic and molecular characteristics of AML in older adult populations, which should caution providers not to reduce therapy intensity on the basis of age alone. Instead, geriatric assessments should be employed to determine fitness for therapy. Treatment options in AML are increasingly targeted to specific mutations or recognized to have differential benefits on the basis of genomics, and representation of older adults and geriatric outcome reporting in clinical trials is improving. Additionally, newer studies have begun to explore personalized therapy strategies on the basis of initial genetic testing. Review and refinement of practice guidelines for older patients on the basis of these advances is needed and is anticipated to remain an important topic in ongoing hematology/oncology clinical education.

Protocol for a pilot randomized controlled trial of a mobile health exercise intervention for older patients with myeloid neoplasms (GO-EXCAP 2).

INTRODUCTION: We have shown the Exercise for Cancer Patients (EXCAP©®) exercise program improved physical function and symptoms and reduced inflammatory markers in patients with cancer. However, adherence to exercise was lower in older adults compared to their younger counterparts. We then leveraged a mobile app to deliver EXCAP©® and adapted the intervention [Geriatric-Oncology (GO)-EXCAP] for older patients with myeloid neoplasms. In this pilot randomized trial, the primary goal is to determine effect sizes. We propose to assess the preliminary efficacy of GO-EXCAP compared to a behavioral placebo control on physical function, patient-reported outcomes (fatigue, mood, and quality of life), and inflammatory markers in 100 patients aged ≥60 years with myeloid neoplasms receiving outpatient chemotherapy. METHODS: GO-EXCAP consists of the EXCAP©® exercise prescription (daily home-based progressive aerobic walking and resistance exercises with rated perceived exercise of 5-8), EXCAP©® kit (i.e., activity tracker, resistance bands, print manual, bag), a mobile app, and an in-person or virtual session with the exercise physiologist to deliver exercise prescription. The intervention will last for three cycles of chemotherapy (approximately 12 weeks). The primary outcome measure will be physical function (Short Physical Performance Battery). Secondary outcome measures include fatigue (Brief Fatigue Inventory), mood (Center for Epidemiologic Studies Depression Scale), and quality of life (Functional Assessment of Cancer Therapy-Leukemia). Exploratory outcome measures include inflammatory markers. DISCUSSION: Older adults with myeloid neoplasms receiving outpatient chemotherapy serve as an ideal model for studying an individually tailored mobile health exercise intervention in vulnerable older patients receiving cancer treatments to prevent physical function decline and improve symptoms.

Factors affecting survival in elderly patients with diffuse large B-Cell lymphoma.

INTRODUCTION: Diffuse large B cell lymphoma (DLBCL) has an increasing incidence in elderly patients with poorer prognosis than in younger patients. Clinicians should clearly identify the characteristics and prognostic factors of elderly patients. We analyzed the outcome of elderly DLBCL patients, especially factors affecting survival in real-life clinical practice. MATERIALS AND METHODS: The data of 330 DLBCL patients at our center were retrospectively evaluated by dividing three groups; younger than 65 years, between 65-79 years, and 80 years and older. We examined the factors affecting survival in DLBCL patients ≥ 65 years old. RESULTS: The median age of the patients was 61 years (range 16-87). 192 (58.2 %) of our patients were younger than 65 years old, 112 (33.9 %) were between 65-79 years, and 26 (7.9 %) patients were 80 years old or older. The median follow-up was 15 (1-120) months. Median PFS was 38 months in the 65-79 years group, ten months in the ≥ 80 years group; meanwhile, median OS was 43 months in the 65-79 years group, 25 months in the ≥80 years group. The number of patients who relapsed within 12 months of the first-line treatment was 69 (35.9 %) in the <65 years group, it was 60 (53.6 %) in 65-79 years group, and 22 (84.6 %) in ≥80 years group (p < 0.001). The median OS was 9 (7.1-10.9) months in DLBCL patients older than 65 years old who relapsed within 12 months. Early relapse, failure to achieve CR after first-line chemotherapy, and high IPI score were associated with poor survival in patients ≥ 65 years old (p:0.001). CONCLUSION: Advancing age was a poor prognostic factor for survival of DLBCL. Relapsing within the first year, or failure to achieve complete remission were associated with poorer survival of the elderly DLBCL patients. R-CHOP is the standard treatment in DLBCL, and the best responses are obtained regardless of age. Due to difficulty in receiving standard treatments, novel treatment modalities are needed for better outcomes in elderly patients with DLBCL.

Developing and adapting a mobile health exercise intervention for older patients with myeloid neoplasms: A qualitative study.

INTRODUCTION: Older patients with myeloid neoplasms (MN) receiving outpatient chemotherapy are at risk of experiencing treatment-related toxicities such as functional decline. A mobile health (mHealth) exercise intervention may ameliorate these toxicities. This qualitative study aimed to inform the design of a mHealth exercise intervention for this population. METHODS: This was a qualitative study of thirteen patients aged ≥60 years receiving hypomethylating agents for MN. EXCAP©® is a home-based walking and progressive resistance exercise program. We combined EXCAP©® with a mobile app; the combination (GO-EXCAP Mobile App) has not been previously tested. A brief verbal description about the intervention was provided to the participants but they did not perform it. Participants were interviewed and inductive thematic analysis was used to analyze the data. RESULTS: Mean age was 71.6 (SD 8.5). Three themes were identified: 1) Perceptions of the intervention feasibility, 2) Ways to leverage the app to deliver the exercise intervention, and 3) Personalized exercise goals. Walking and resistance exercises were perceived to be feasible. Patients were comfortable initiating the intervention in cycle 2 of chemotherapy, with exercise increments occurring from week 2-4 of the cycle. Ways to leverage the app to deliver EXCAP©® include 1) Video feature for exercise demonstration and interactions, and 2) Exercise data and symptom surveys to be communicated to the exercise physiologist and primary oncology team. Preservation of existing function and activity was an important goal to participants. CONCLUSIONS: Our findings provide insights about the preferences of older adults with MN for a mHealth exercise intervention.

The use of frailty assessments in treating older adults with aggressive lymphomas.

Non-Hodgkin lymphomas (NHL) are most commonly diagnosed among people aged 65-74 years, with a median age at diagnosis of 67 years. The percentage of NHL-related deaths is highest among people aged 75-84 years, with a median age at death of 76 years from cases between 2014 and 2018. In light of these recent data, attending physicians of patients with NHL will recognize that the majority of their patients will be of advanced age, with many suffering from a spectrum of frailties. The excess rate of death among older adults with NHL may be related to a range of different factors such as more challenging biologic features, undertreatment received due to a patient's chronology and treatment-related toxicity. The aim of this review is to provide an updated overview of the knowledge generated over recent years regarding epidemiology, prognosis and treatment options in older adults with lymphoma, focusing on Diffuse Large B-cell Lymphoma (DLBCL) where the most robust evidence base is available.

Treatment decision-making in acute myeloid leukemia: a qualitative study of older adults and community oncologists.

Little is known about the characteristics of patients, physicians, and organizations that influence treatment decisions in older patients with AML. We conducted qualitative interviews with community oncologists and older patients with AML to elicit factors that influence their treatment decision-making. Recruitment was done via purposive sampling and continued until theoretical saturation was reached, resulting in the inclusion of 15 patients and 15 oncologists. Participants' responses were analyzed using directed content analysis. Oncologists and patients considered comorbidities, functional status, emotional health, cognition, and social factors when deciding treatment; most oncologists evaluated these using clinical gestalt. Sixty-seven percent of patients perceived that treatment was their only option and that they had not been offered a choice. In conclusion, treatment decision-making is complex and influenced by patient-related factors. These factors can be assessed as part of a geriatric assessment which can help oncologists better determine fitness and guide treatment decision-making.

Management of Acute Myeloid Leukemia (AML) in Older Patients.

PURPOSE OF REVIEW: The acute myeloid leukemia (AML) treatment landscape has rapidly evolved over the past few years. These changes have several implications for the care of older adults (≥ 60 years), who have inferior clinical outcomes. We review decision-making in older adults, focusing on patient- and disease-related factors. We then summarize current treatment options, including multiple recently approved therapies, based on hypothetical clinical scenarios. RECENT FINDINGS: In lieu of using chronological age to determine fitness, we highlight the importance of standardized fitness assessments using geriatric assessments. Next, we review intensive and lower-intensity treatment options in the upfront setting. We focus on multiple newly approved medications, including venetoclax, midostaurin, CPX-351, gemtuzumab, glasdegib, enasidenib, and ivosidenib, and their specific indications. Lastly, we briefly discuss supportive care of older adults with AML. Outcomes of older adults with AML remain poor; fortunately, there are many new promising treatment options. Personalized treatment plans based on patient- and disease-specific factors are essential to the care of older adults with AML.

Assessment of older adult candidates for allogeneic hematopoietic cell transplantation: updates and remaining questions.

INTRODUCTION: Allogeneic hematopoietic cell transplantation (allo-HCT) has seen marked growth among older adults, where chronological age is no longer a barrier to transplant. As allo-HCT expands to older and potentially less fit individuals, prognosticating transplant outcomes in this population remains an ongoing need. Areas covered: This review summarizes pre-transplant assessment tools in optimizing patient selection and predicting transplant outcomes in older adults, including comorbidity indices, psychosocial assessment, geriatric assessment, serum biomarkers, and disease risk. This review also discusses the impact of donor age and clonal hematopoiesis of indeterminate significance on transplant outcomes. Expert commentary: Determining which patients should be referred for transplant remains challenging, especially in older adults. Chronological age is an insufficient prognostic metric, and refining, validating, and developing novel pre-transplant risk assessment tools for geriatric patients offers great potential benefit to the field.
