Frailty and the management of hematologic malignancies

Evaluating the cancer aging and research group model in predicting immunochemotherapy toxicity among elderly patients with diffuse large B-cell lymphoma

BACKGROUND

The management of diffuse large B-cell lymphoma (DLBCL) in elderly patients is complicated by an increased risk of treatment-related toxicity associated with aging. This study aimed to validate the effectiveness of the Cancer Aging and Research Group (CARG) model in elderly patients with DLBCL receiving rituximab-based chemotherapy.

METHODS

In this prospective study, elderly DLBCL patients (aged 65 years or older) receiving rituximab-based chemotherapy were consecutively assessed between August 2016 and December 2021 at one medical center in Taiwan using the CARG model to predict treatment-related toxicity. Patients were categorized into low-, medium-, and high-risk groups based on their CARG scores. Comparisons were made regarding toxicities and survival rates among these groups.

RESULTS

Ninety-one patients, with a median age of 70 years (range 65-96), were included. A substantial 81 % (74 patients) experienced grade 3-5 toxicity. The overall 2-year survival rate was 63.8 % after a median follow-up of 28 months (range, 2-46). The risk of grade 3-5 toxicity was 83 %, 78 %, and 87 %, respectively, among the low-, medium-, and high-risk groups (p = 0.60). The receiver operating characteristic (ROC) curve for CARG was 0.521 (95 % CI, 0.376-0.666), which was significantly lower than that for the Eastern Cancer Oncology Group score (ROC = 0.701, 95 % CI, 0.571-0.831). Similarly, compared with those of low-risk patients, hazard ratios for overall survival were 9.22 (95 % CI, 1.23-69.1; p = 0.031) and 14.6 (95 % CI, 1.90-112; p = 0.010) for medium- and high-risk patients, respectively.

CONCLUSION

While CARG exhibited limitations in predicting treatment-related toxicity in elderly DLBCL patients, it demonstrated potential efficacy in predicting survival outcomes.

Frailty: An Underappreciated Risk Factor for IBD Complications

PURPOSE OF REVIEW

The prevalence of IBD in older adults is rapidly growing. Older adults with IBD are underrepresented in research and clinical trials and yet at great risk for adverse events. Therefore, understanding advanced aged associated constructs in older adults can be critical to improving the management of older adults with IBD.

RECENT FINDINGS

In this review, we present recent studies on frailty in IBD. We identify 4 major themes in the literature: studies that describe frailty in patients with IBD, studies that report on consequences of frailty, studies of frailty as a risk stratification modality, and studies of frailty as an exposure and outcome. In reviewing the literature, we discuss the heterogeneity that exists and outline future directions to ensure appropriate applications for frailty in the field of IBD.

Review of Baduanjin and resistance exercise for the mental health of patients with hematologic malignancies

Patients with hematological tumors experience physical and psychological stress, and negative psychological states. Baduanjin, an emerging psychological rehabilitation method combined with resistance exercise, has received widespread attention. This study reviews the current status of the application of Baduanjin combined with resistance exercise in improving the negative psychological state of patients with hematological tumors and discusses its problems and prospects. Through a literature review and comprehensive analysis, the application of Baduanjin and resistance exercise in the psychological rehabilitation of patients with hematological tumors was identified and evaluated. The results showed that Baduanjin with resistance exercise had a positive effect on improving negative psychological states of patients with hematological tumors, which can alleviate anxiety, depression, and other adverse emotions, and improve quality of life. However, there is a lack of unified and standardized exercise intervention programs for practical application, and patient participation and compliance must be improved. Baduanjin combined with resistance exercise can potentially improve the negative psychological status of patients with hematological tumors; however, it is still necessary to further standardize and improve the exercise program improving patient participation and compliance. Future studies should strengthen theoretical exploration and empirical research, providing more effective psychological rehabilitation strategies for patients with hematological tumors.

Modified Delphi panel consensus recommendations for management of severe aplastic anemia

ABSTRACT

Severe aplastic anemia (SAA) is a rare hematologic condition for which there is no clear management algorithm. A panel of 11 experts on adult and pediatric aplastic anemia was assembled and, using the RAND/University of California, Los Angeles modified Delphi panel method, evaluated >600 varying patient care scenarios to develop clinical recommendations for the initial and subsequent management of patients of all ages with SAA. Here, we present the panel's recommendations to rule out inherited bone marrow failure syndromes, on supportive care before and during first-line therapy, and on first-line (initial management) and second-line (subsequent management) therapy of acquired SAA, focusing on when transplant vs medical therapy is most appropriate. These recommendations represent the consensus of 11 experts informed by published literature and experience. They are intended only as general guidance for experienced clinicians who treat patients with SAA and are in no way intended to supersede individual physician and patient decision making. Current and future research should validate this consensus using clinical data. Once validated, we hope these expert panel recommendations will improve outcomes for patients with SAA.

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.

Medication reconciliation in hospitalized hematological patient

OBJECTIVE

The main objective was to analyze unjustified discrepancies during the medication reconciliation process in patients admitted to the Hematology Service of our hospital and the pharmaceutical interventions. As a secondary objective, to detect possible points of the procedure to be perfected with a view to protocolizing the medication reconciliation process in hematological patients that adapts to the conditions of our center.

METHODS

Cross-sectional observational pilot study carried out in a reference hospital in hematology for a population of 800,000 inhabitants. Adult inpatients admitted to the Hematology Service between August and October 2022 whose medication had been reconciled were included. The main variables were: number and type of unjustified discrepancy, proposed pharmaceutical intervention, and acceptance rate.

RESULTS

36 conciliation processes were analyzed, 34 admissions and 2 intrahospital transfer. 58.3% of the patients presented at least one unjustified discrepancy. 38 unjustified discrepancies were detected, with an acceptance of pharmaceutical interventions of 97.4%. The most common types of discrepancy were medication omission (56.8%) and drug interaction (24.3%). The most frequent pharmaceutical interventions were reintroducing medication (48.6%) and treatment discontinuation (16.2%). Polypharmacy and chemotherapy multiplied by 4 the probability of presenting drug interactions.

CONCLUSIONS

The most common unjustified discrepancies in the medication reconciliation process in hospitalized hematology patients are: Medication omission and drug interactions. The reintroduction of medication and suspension of the prescription are the most frequent accepted pharmaceutical interventions. Polypharmacy is related to an increase in unjustified discrepancies. The factors that promote the appearance of interactions are admissions to receive chemotherapy treatment and polypharmacy. The main point of improvement detected is the need to create a circuit that allows conciliation to be carried out on discharge. Medication reconciliation contribute to improving patient safety by reducing medication errors.

Optimization of mHealth behavioral interventions for patients with chronic lymphocytic leukemia: the HEALTH4CLL study

PURPOSE

This pilot study of a diet and physical activity intervention (HEALTH4CLL) was conducted to reduce fatigue and improve physical function (PF) in patients with chronic lymphocytic leukemia (CLL).

METHODS

The HEALTH4CLL study used a randomized factorial design based on the multiphase optimization strategy (MOST). Patients received diet, exercise, and body weight management instructional materials plus a Fitbit and were randomized to undergo one of 16 combinations of 4 evidence-based mHealth intervention strategies over 16 weeks. Patients' fatigue, PF, health-related quality of life, behavior changes, and program satisfaction and retention were assessed. Paired t-tests were used to examine changes in outcomes from baseline to follow-up among patients. Factorial analysis of variance examined effective intervention components and their combinations regarding improvement in fatigue and PF scores.

RESULTS

Among 31 patients, we observed significant improvements in fatigue (+ 11.8; t = 4.08, p = 0.001) and PF (+ 2.6; t = 2.75, p = 0.01) scores. The combination of resistance and aerobic exercise with daily self-monitoring was associated with improved fatigue scores (β = 3.857, SE = 1.617, p = 0.027). Analysis of the individual components of the MOST design demonstrated greater improvement in the PF score with resistance plus aerobic exercise than with aerobic exercise alone (β = 2.257, SE = 1.071, p = 0.048).

CONCLUSIONS

Combined aerobic and resistance exercise and daily self-monitoring improved PF and reduced fatigue in patients with CLL.

IMPLICATIONS FOR CANCER SURVIVORS

This pilot study supported the feasibility of a low-touch mHealth intervention for survivors of CLL and provided preliminary evidence that exercising, particularly resistance exercise, can improve their symptoms and quality of life.

The causal association between circulating cytokines with the risk of frailty and sarcopenia under the perspective of geroscience

Introduction

Circulating cytokines were considered to play a critical role in the initiation and propagation of sarcopenia and frailty from observational studies. This study aimed to find the casual association between circulating cytokines and sarcopenia and frailty from a genetic perspective by two-sample Mendelian randomization (MR) analysis.

Methods

Data for 41 circulating cytokines were extracted from the genome-wide association study dataset of 8,293 European participants. Inverse-variance weighted (IVW) method, MR-Egger, and weighted median method were applied to assess the relationship of circulating cytokines with the risk of aging-related syndromes and frailty. Furthermore, MR-Egger regression was used to indicate the directional pleiotropy, and Cochran's Q test was used to verify the potential heterogeneity. The "leave-one-out" method was applied to visualize whether there was a causal relationship affected by only one anomalous single-nucleotide polymorphisms.

Results

Genetic predisposition to increasing levels of interleukin-10 (IL-10), IL-12, and vascular endothelial growth factor (VEGF) was associated with the higher risk of low hand grip strength according to the IVW method [R = 1.05, 95% CI = 1.01-1.10, P = 0.028, false discovery rate (FDR)-adjusted P = 1.000; OR = 1.03, 95% CI = 1.00-1.07, P = 0.042, FDR-adjusted P = 0.784; OR = 1.02, 95% CI = 1.00-1.05, P = 0.038, FDR-adjusted P = 0.567]. Furthermore, genetically determined higher macrophage colony-stimulating factors (M-CSFs) were associated with a lower presence of appendicular lean mass (OR = 1.01, 95% CI = 1.00-1.02, P = 0.003, FDR-adjusted P = 0.103). Monokine induced by interferon-γ (MIG) and tumor necrosis factor-beta (TNF-β) were associated with a higher risk of frailty (OR = 1.03, 95% CI = 1.01-1.05, P < 0.0001, FDR-adjusted P = 0.012; OR = 1.01, 95% CI = 1.00-1.03, P = 0.013, FDR-adjusted P = 0.259). In this study, we did not find heterogeneity and horizontal pleiotropy between the circulating cytokines and the risk of frailty and sarcopenia.

Conclusion

Genetic predisposition to assess IL-10, IL-12, and VEGF levels was associated with a higher risk of low hand grip strength and M-CSF with the presence of appendicular lean mass. The high levels of TNF-β and MIG were associated with a higher risk of frailty. More studies will be required to explore the molecular biological mechanisms underlying the action of inflammatory factors.

A Markov analysis of azacitidine and venetoclax vs induction chemotherapy for medically fit patients with AML

ABSTRACT

Although induction chemotherapy (IC) is the standard of care in medically fit patients with newly diagnosed acute myeloid leukemia (AML), limited retrospective data indicate that patients at adverse-risk may benefit from azacytidine and venetoclax (aza-ven). Our goal was to perform a Markov decision analysis to determine whether IC or aza-ven is the optimal induction regimen in this population. Using the TreeAge software, Markov models were created for adverse-risk and intermediate-risk cohorts. A systematic review of the literature informed the transition probabilities and utilities included in the analyses. Our primary outcome was quality-adjusted life years (QALYs) gained over 5 years after diagnosis. Overall, patients at adverse risk treated with IC gained 1.4 QALYs, compared with 2.0 QALYs in patients treated with aza-ven. Patients at adverse risk treated with IC and allogeneic stem cell transplantation (allo-SCT), IC, aza-ven and allo-SCT, or aza-ven gained 2.1, 1.5, 3.0, and 1.9 QALYs, respectively. Meanwhile, patients at intermediate risk treated with IC gained 2.0 QALY, compared with 1.7 QALY in patients treated with aza-ven. Patients at intermediate risk treated with IC and allo-SCT, IC, aza-ven and allo-SCT, and aza-ven gained 2.7, 2.3, 2.6, and 1.8 QALYs, respectively. We have demonstrated that medically fit patients with newly diagnosed adverse-risk AML may benefit from treatment with aza-ven over those treated with IC, whereas IC remains the preferred approach for patients at intermediate risk. Our work challenges the use of the European LeukemiaNet risk classification for patients treated with aza-ven and highlights the need for prospective investigation into aza-ven as induction therapy for medically fit patients.

Assessing Frailty in Gastrointestinal Cancer: Two Diseases in One?

PURPOSEOF REVIEW

This review examines the challenges of treating gastrointestinal cancer in the aging population, focusing on the importance of frailty assessment. Emphasized are the rise in gastrointestinal cancer incidence in older adults, advances in frailty assessments for patients with gastrointestinal cancer, the development of novel frailty markers, and a summary of recent trials.

RECENT FINDINGS

Increasing evidence suggests that the use of a Comprehensive Geriatric Assessment (CGA) to identify frail older adults and individualize cancer care leads to lower toxicity and improved quality of life outcomes. However, the adoption of a full CGA prior to chemotherapy initiation in older cancer patients remains low. Recently, new frailty screening tools have emerged, including assessments designed to specifically predict chemotherapy-related adverse events. Additionally, frailty biomarkers have been developed, such as blood tests like IL-6 and performance tracking through physical activity monitors. The relevance of nutrition and muscle mass is discussed. Highlights from recent trials suggest the feasibility of successfully identifying patients most at risk of serious adverse events. There have been promising developments in identifying novel frailty markers and methods to screen for frailty in the older adult population. Further prospective trials that focus on and address the needs of the geriatric population for early identification of frailty in cancer care, facilitating a more tailored treatment approach. Practicing oncologists should select a frailty assessment to implement into their routine practice and adjust treatment accordingly.

Frailty assessment to individualize treatment in older patients with lymphoma

PURPOSE

A study analyzing the application of a protocol of comprehensive geriatric assessment (CGA) in older patients with lymphoma was carried out to allow frailty-based patient classification and individualized treatment.

METHODS

Lymphoma patients older than 70 years referred to the Geriatric Clinic at a tertiary hospital between May 2016 and March 2021 were included. The assessment protocol included comorbidity, polypharmacy, nutritional, functional, and mental status, geriatric syndromes, and life expectancy. CGA enabled patient classification into four groups (Type I to Type IV) based on frailty assessment instrument scoring and clinical, functional, and mental status. Variables were compared using parametric and non-parametric statistical tests and Kaplan-Meier survival curves.

RESULTS

Ninety-three patients (55.9% women) were included. Median age was 81.1 years (± 5.7). 23 patients (24.7%) were classified as robust (type I), 30 (32.3%) as pre-frail (type II) with potentially reversable deficits, 38 (40.9%) as frail (type III), and 2 (2.2%) as requiring palliative care (type IV). Patients received oncospecific treatment with modifications carried out in 64.5% of cases based on CGA results. Differences in overall survival (p = 0.002), response to treatment (p < 0.001) and likelihood of increased frailty (p = 0.024) were observed, with type III-IV patients showing significantly worse outcomes.

CONCLUSION

Performance of standardized, systematic CGA by geriatricians permits older lymphoma patients to be classified according to frailty, with significant differences in terms of clinical outcomes across groups. We propose incorporating CGA performed by geriatricians as part of the multidisciplinary care team to optimize therapeutic strategy for these patients.

Supportive Care in Older Lymphoma Patients to Reduce Toxicity and Preserve Quality of Life

The treatment paradigm in older patients with malignant hemopathies is the choice between an effective conservative treatment that preserves quality of life and an intensive, potentially curative treatment with more toxicities. For each patient, it is important to determine the risk/benefit ratio. The patient should be involved in the discussion, sufficiently informed and able to express himself and his expectations in terms of quality of life. However, this informed consent is conditioned by the ability of the patient to understand the risks and benefits of the treatment. Decline in quality of life is an important parameter for older patients with cancer and many prospective trials have now confirmed the impact of different side effects of treatment, such as recurrent hospitalization, loss of autonomy in daily activities, loss of contact with grandchildren and loss of cognitive functions. Interventions oriented to vulnerabilities detected in the older patients (by comprehensive geriatric assessment) and an optimal approach, including preventive measures to reduce treatment-related toxicity and mortality, are directly correlated to improvement in quality of life.

HCT frailty scale for younger and older adults undergoing allogeneic hematopoietic cell transplantation

The HCT Frailty Scale is an easy prognostic tool composed of (a) Clinical Frailty Scale; (b) Instrumental Activities of Daily Living; (c) Timed-up-and-Go test; (d) Grip Strength; (e) Self-Health Rated Questionnaire; (f) Falls tests; (g) Albumin and C-reactive protein levels. This scale was designed to classify allogeneic hematopoietic cell transplant (alloHCT) candidates into fit, pre-frail and frail groups, irrespective of age. This study evaluates the ability of this frailty classification to predict overall survival (OS) and non-relapse mortality (NRM) in adult patients of all ages, in a prospective sample of 298 patients transplanted between 2018 and 2020. At first consultation, 103 (34.6%) patients were fit, 148 (49.7%) pre-frail, and 47 (15.8%) were frail. The 2-year OS and NRM of the three groups were 82.9%, 67.4%, and 48.3% (P < 0.001), and 5.4%, 19.2%, and 37.7% (P < 0.001). For patients younger than 60 years (n = 174), the 2-year OS and NRM of fit, pre-frail, and frail groups were 88.4%, 69.3% and 53.1% (P = 0.002), and 5.8%, 22.8%, and 34.8% (P = 0.005), respectively; and in patients older than 60 (n = 124), OS and NRM were 75.5%, 63.8% and 41.4% (P = 0.006), and 4.9%, 16.4%, and 42.1% (P = 0.001). In conclusion, frailty predicted worse transplant outcomes in both younger and older adults.

Prognostic Potential of Pulmonary Hypertension in Patients with Hematologic Malignancy

INTRODUCTION

Cardiovascular diseases present a great burden for survivors of hematologic malignancy (HM). However, the effect of pulmonary hypertension (PH) on the clinical outcome of patients with HM remains unknown. This study aims to evaluate the prognostic potential of PH in patients with HM and explore the related clinical determinants.

METHODS

This retrospective study included 220 patients with HM and PH and 220 controls without PH, the case-matching cohort analysis was performed based on age, sex, the year of diagnosis and disease type. The baseline characteristics and overall survival (OS) of the patients with HM with or without PH were compared. The cumulative overall survival was analyzed using the Kaplan-Meier curves and the log-rank test. Multivariate Cox proportional hazard models were conducted to identify the predictors of OS.

RESULTS

PH was found in 11.98% (302/2520) of the patients with HM. The PH group had lower levels of hemoglobin, platelet, albumin, fibrinogen and B cell count; whereas the levels of lactate dehydrogenase, N terminal pro B type natriuretic peptide, D-dimer, fibrinogen degradation products and C-reactive protein were higher. Additionally, the PH group had a higher prevalence of atrial fibrillation. Survival analysis revealed that the PH group had an inferior OS compared to the non-PH group (16.9 vs. 37.6 months, p = 0.002). Further subgroup analysis revealed that the severe PH group had the worst OS, followed by the moderate and the mild PH groups (8.7 vs. 14.7 vs. 23.7 months, p < 0.001). Multivariate analysis showed that PH was an independent predictor for unfavorable clinical outcomes.

CONCLUSIONS

Coexisting PH was associated with inferior clinical outcomes in patients with HM, and the severe PH group had the worst prognosis. The study may provide additional risk stratification for patients with HM.

How does hospitalization affect the frailty status of geriatric patients? Prospective study from internal medicine wards of a university hospital

OBJECTIVES

Frailty is a dynamic process. Frailty in the baseline, discharge, and post-discharge are important in the management of patients. We aimed to see how hospitalization affects frailty and to evaluate its effects on health outcomes.

METHODS

It was conducted with patients aged 65 and over who were hospitalized in the internal medicine wards of a university hospital. Frailty was evaluated by Clinical Frailty Scale within the first 24 h of hospitalization, within 24 h before discharge, and at third months after discharge.

RESULTS

Ninety-six (57.8%) of patients at baseline, 79 (50.6%) at discharge, and 68 (47.9%) at 3 months were frail. According to baseline, 12 (7.7%) patients changed from frail to non-frail at discharge, while 4 (2.6%) patients became frail (p = 0.08). According to the baseline, 18 (12.5%) patients went from frail to non-frail at 3 months, while 7 (4.9%) patients turned frail (p = 0.04). In regression analysis, living with frailty at discharge and low education level increased re-hospitalization. Five or more are considered living with frailty.

DISCUSSION

Hospitalization may have positive effects on frailty in older adult patients hospitalized in internal medicine wards, the main effect is seen to be more significant in the post-discharge follow-up.

Hand grip strength, short physical performance battery, and gait speed: key tools for function in Non-Hodgkin Lymphoma

This study aimed to determine which performance assessment tools included in Comprehensive Geriatric Assessment (CGA) are the most sensitive for the functional approach in the initial evaluation and during the therapy of old adults diagnosed with Diffuse Large B-Cell Lymphoma (DLBCL). We prospectively recruited 31 patients aged 70 years or older presenting for an initial consultation in the Hematology Clinic of a tertiary hospital. We implemented an updated physical performance evaluation as part of CGA at baseline and during treatment. Baseline characteristics of the sample were compared according to age, Geriatric 8 (G8), frailty, Short Physical Performance Battery (SPPB), and sarcopenia measured by hand grip strength (HGS). Functional changes were monitored during the treatment period using HGS, gait speed (GS) and SPPB. The mean age was 79.0 (5.5) years and 51.6% of the sample was frail; 65,5% were treated with standard chemotherapy and 35,5% with a therapeutic regimen with attenuated doses. All the assessment tools included in CGA found functional differences at baseline when the sample was stratified and compared according to frailty, sarcopenia, and SPPB, but not according to G8 score and age. Only SPPB was able to detect functional differences between groups stratified by age at baseline. GS was the only score that identified clinically significant functional changes during the treatment. In conclusion, HGS and SPPB are appropriate performance scores to complete the functional approach in the initial hematologic evaluation, and GS is a promising option to detect functional decline during therapy in old adults with DLBCL.

Drug-drug interactions and dose management of BTK inhibitors when initiating nirmatrelvir/ritonavir (paxlovid) based on physiologically-based pharmacokinetic models

OBJECTIVE

Co-administration of Bruton's tyrosine kinase (BTK) inhibitors with nirmatrelvir/ritonavir is challenging because of potential drug-drug interactions (DDIs). However, clinical trials specifically evaluating such DDIs are absent. To evaluate and quantify the DDIs between them and provide rational dose management strategies of BTK inhibitors, we conducted this study using physiologically-based pharmacokinetic (PBPK) models.

METHODS

Physicochemical properties and pharmacokinetic parameters were acquired from the published literature and databases. The PBPK models were developed using Simcyp® software. These models were validated by comparing with published literature values. The successfully validated PBPK models were used to simulate the plasma concentration-time profiles and DDIs in a virtual healthy population receiving BTK inhibitors alone or with ritonavir.

RESULTS

Simulated plasma concentration-time profiles and pharmacokinetic parameters of each drug were in agreement with clinically observed values from literatures. Ritonavir increased ibrutinib maximum plasma concentration (Cmax) and the area under plasma concentration-time curve (AUC) 33- and 53.88-fold, respectively, increased zanubrutinib Cmax and AUC 2.57- and 3.18-fold, respectively, and increased acalabrutinib Cmax and AUC 3.85- and 6.54-fold, respectively. Based on our simulations, dose-adjustment strategies may consist of ibrutinib at 25 mg q48h, zanubrutinib at 80 mg twice-daily and acalabrutinib at 25 mg twice-daily with nirmatrelvir/ritonavir.

CONCLUSIONS

The PBPK models predicted the in vivo pharmacokinetics and the DDIs of BTK inhibitors and ritonavir. The prospective simulations not only provided scientific evidence regarding rational dosing management strategies when initiating nirmatrelvir/ritonavir therapy but also provided a reference for the design of clinical DDIs study that may save resources and time.

SUMMARY

Paxlovid could increase Cmax and AUC0-τ of BTK inhibitors (ibrutinib, zanubrutinib and acalabrutinib), and dose adjustment strategy of ibrutinib (25 mg q48h), zanubrutinib (80 mg q12h) and acalabrutinib (25 mg q12h) should be considered when combination with nirmatrelvir/ritonavir.

Assessment of an embedded primary care-derived electronic health record (EHR) frailty index (eFI) in older adults with acute myeloid leukemia

INTRODUCTION

Assessing frailty is integral to treatment decision-making for older adults with acute myeloid leukemia (AML). Prior electronic frailty indices (eFI) derive from an accumulated-deficit model and are associated with mortality in older primary care populations. We evaluated use of an embedded eFI in AML by describing baseline eFI categories by treatment type and exploring associations between eFI categories, survival, and treatment received.

MATERIALS AND METHODS

This was a retrospective study of subjects ≥60 years old with new AML treated at an academic medical center from 1/2018-10/2020. The eFI requires ≥2 ambulatory visits over two years and uses demographics, vitals, ICD-10 codes, outpatient labs, and available functional information from Medicare Annual Wellness Visits. Frailty was defined as fit (eFI ≤ 0.10), pre-frail (0.10 < eFI ≤ 0.21), and frail (eFI > 0.21). Chemotherapy was intensive (anthracycline-based) or less-intensive (hypomethylating agent, low dose cytarabine +/- venetoclax). Therapy type, pre-treatment characteristics, and chemotherapy cycles were compared by eFI category using chi-square and Fisher's exact tests and ANOVA. Median survival was compared by eFI category using log-rank tests stratified by therapy type.

RESULTS

Among 166 older adults treated for AML (mean age 74 years, 61% male, 85% Caucasian), only 79 (48%) had a calculable eFI score before treatment. Of these, baseline eFI category was associated with treatment received (fit (n = 31): 68% intensive, 32% less intensive; pre-frail (n = 38): 37% intensive, 63% less intensive; frail (n = 10): 0% intensive, 100% less intensive; not calculable (n = 87): 48% intensive, 52% less-intensive; p < 0.01). The prevalence of congestive heart failure and secondary AML differed by frailty status (p < 0.01). Median survival did not differ between eFI categories for intensively (p = 0.48) or less-intensively (p = 0.09) treated patients. For those with less-intensive therapy who lived ≥6 months, eFI category was not associated with the number of chemotherapy cycles received (p = 0.97). The main reason for an incalculable eFI was a lack of outpatient visits in our health system prior to AML diagnosis.

DISCUSSION

A primary care-derived eFI was incalculable for half of older adults with AML at an academic medical center. Frailty was associated with chemotherapy intensity but not survival or treatment duration. Next steps include testing adaptations of the eFI to the AML setting.

Cholesterol alone or in combination is associated with frailty among community-dwelling older adults: A cross-sectional study

BACKGROUND

Biological markers contribute to the precise intervention across the continuum of frailty severity. Few studies have explored the advantages of biological markers collected as part of primary care data among community-dwelling older adult population and controversy remains regarding the classic biological markers for frailty.

METHODS

We recruited a total of 8791 adults with a mean age of 71.95 years who met the inclusion and exclusion criteria in Guancheng District and Dalang Town, Dongguan, China. Frailty was assessed by a Chinese frailty evaluation scale. Frailty status was classified with 33-item modified frailty index and latent class analysis was applied to explore the latent classes (subtypes) of frailty. We measured biological markers on blood samples collected. We identify association between specific biological markers or patterns and frailty by logistic regression and association rule mining (ARM) based on the Apriori algorithm.

RESULTS

Multivariable analysis of our data showed that an elevated white blood cell (WBC) count and high cholesterol (CHOL) level were associated with pre-frailty (adjusted odds ratio [aOR] = 1.231, 95 % confidence interval [CI] = 1.009-1.501; aOR = 0.703, 95 % CI = 0.623-0.793) and frailty (aOR = 1.500, 95 % CI = 1.130-1.993; aOR = 0.561, 95 % CI = 0.461-0.684) compared with the normal groups. Importantly, significantly high level of CHOL was associated with a lower risk of four frailty subtypes compared with relatively healthy participants with the most power of association in the multi-frail group (aOR = 0.182, 95 % CI = 0.086-0.386). Based on ARM technique to develop correlation analysis to identify important high-risk clusters among older adult transitions from non-frail to frailty, patterns for normal level of CHOL co-occurred with an elevated creatinine (CREA) level have a significant association with the risk of frailty (aOR = 7.787, 95 % CI = 1.978-30.648) after adjusting for targeted confounders.

CONCLUSIONS

Our study highlights the correlation between classic biological markers, especially CHOL and frailty status and subtypes among community-dwelling older adult, in the primary care setting. Further large-scale prospective studies are still needed to confirm the role of classic biological markers in frailty.

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.

Considerations for Drug Development in Myelodysplastic Syndromes

Myelodysplastic syndromes (MDS) have historically been challenging diseases for drug development due to their biology, preclinical modeling, and the affected patient population. In April 2022, the FDA convened a panel of regulators and academic experts in MDS to discuss approaches to improve MDS drug development. The panel reviewed challenges in MDS clinical trial design and endpoints and outlined considerations for future trial design in MDS to facilitate drug development to meaningfully meet patient needs. Challenges for defining clinical benefit in patients with MDS include cumbersome response criteria, standardized transfusion thresholds, and application and validation of patient reported outcome instruments. Clinical trials should reflect the biology of disease evolution, the advanced age of patients with MDS, and how patients are treated in real-world settings to maximize the likelihood of identifying active drugs. In patients with lower-risk disease, response criteria for anemic patients should be based on baseline transfusion dependency, improvement in symptoms, and quality of life. For higher-risk patients with MDS, trials should include guidance to prevent dose reductions or delays that could limit efficacy, specify minimal durations of treatment (in the absence of toxicity or progression), and have endpoints focused on overall survival and durable responses. MDS trials should be designed from the outset to allow the practicable application of new therapies in this high-needs population, with drugs that can be administered and tolerated in community settings, and with endpoints that meaningfully improve patients' lives over existing therapies.

The Effects of Second Primary Malignancies and Frailty on Overall Survival and Mortality in Geriatric Turkish Patients with Multiple Myeloma

The study aims to investigate second primary malignancy (SPM) development and frailty in Turkish geriatric patients with multiple myeloma (MM) and to assess the relationship between overall survival (OS) and various characteristics including SPM and frailty. Seventy-two patients diagnosed with and treated for MM were enrolled in the study. Frailty was determined by the IMWG Frailty Score. Fifty-three participants (73.6%) were found to have clinically-relevant frailty. Seven patients (9.7%) had SPM. Median follow-up was 36.5 (22-48.5) months, and 17 patients died during the follow-up period. Overall (OS) was 49.40 (45.01-53.80) months. Shorter OS was found in patients with SPM (35.29 (19.66-50.91) months) compared to those without (51.05 (46.7-55.4) months) (Kaplan-Meier; p = 0.018). The multivariate cox proportional hazards model revealed that patients with SPM had 4.420-fold higher risk of death than those without (HR: 4.420, 95% CI: 1.371-14.246, p = 0.013). Higher ALT levels were also independently associated with mortality (p = 0.038). The prevalence of SPM and frailty was high in elderly patients with MM in our study. The development of SPM independently reduces survival in MM; however, frailty was not found to be independently associated with survival. Our results suggest the importance of individualized approaches in the management of patients with MM, particularly with regard to SPM development.

Health-related quality of life and use of medication with anticholinergic activity in patients with multiple myeloma

PURPOSE

Verify the association between anticholinergic burden and health-related quality of life of patients with multiple myeloma.

METHODS

Cross-sectional study with multiple myeloma outpatient from a state capital city in southeastern Brazil. Sociodemographic, clinical, and pharmacotherapeutic variables were collected by interview. Clinical data were complemented by medical records. Drugs with anticholinergic activity were identified with Brazilian Anticholinergic Activity Drug Scale. Health-related quality of life scores were obtained using QLQ-C30 and QLQ-MY20 instruments. Mann-Whitney was used to compare the median of the health-related quality of life scale scores and the independent variables. Multivariate linear regression was performed to verify the association between independent variables and health-related quality of life scores.

RESULTS

Two hundred thirteen patients were included, 56.3% had multi-morbidities, and 71.8% used polypharmacy. In all health-related quality of life domains, there were differences between the medians of the polypharmacy variable. A significant difference was identified between the ACh burden and QLQ-C30 and QLQ-MY20 scores. Linear regression identified an association between the use of drugs with anticholinergic activity and the reduction of global status scores (QLQ-C30), functional scale (QLQ-C30), body image (QLQ-MY20), and future perspective (QLQ-MY20). Drugs with anticholinergic activity were associated with increased symptom scores (QLQ-C30 and QLQ-MY20). Polypharmacy was associated with reduction of functioning score and increase of symptom score (QLQ-C30).

CONCLUSION

Anticholinergic burden in MM patients is associated with lower scores in quality of life domains: global health and symptoms (QLQ-C30) and functional (QLQ-C30 and QLQ-MY20). The presence of polypharmacy is also associated with lower scores for functional scales and symptom scales (QLQ-C30).

Frailty in Patients with Chronic Graft-versus-Host Disease

Frailty is an increasingly recognized clinical diagnosis associated with high risk of disability and mortality. Frailty in patients after hematopoietic cell transplantation (HCT) is associated with increased nonrelapse mortality (NRM) and decreased overall survival (OS). Frailty has not been studied extensively in patients with chronic graft-versus-host disease (cGVHD). The objectives of the present study were to assess the prevalence and clinical correlates of frailty and the association of frailty with NRM and OS in patients enrolled in the Chronic GVHD Consortium. Patients were characterized as frail if they met the Fried definition of ≥3 of the following criteria at enrollment: unintentional weight loss, exhaustion, slow walking speed, low physical activity, and weakness. Frailty was assessed retrospectively using surrogate measures for the 5 domains of frailty. Frailty, cGVHD organ scores, and patient-reported outcomes were measured at the time of enrollment. The study included 399 patients from 9 centers in the United States, with 32% characterized as frail and 68% as not frail. The median duration of follow-up from enrollment was 9 years (interquartile range, 7 to 11 years). Frail patients were more likely to be older (P = .004), to have a lower Karnofsky Performance Status (P < .001), to have severe cGVHD (P < .001), and to have gastrointestinal (P < .001), liver (P = .04), or lung cGVHD (P = .002). In a multivariable analysis, older age, increased cGVHD global severity, and thrombocytopenia were statistically significantly associated with frailty when cGVHD organ involvement was excluded. A separate analysis excluding cGVHD severity and including organ involvement showed that lung and liver cGVHD and older age were associated with frailty. Neither corticosteroid use at the time of enrollment nor the maximum recorded dose of corticosteroids before enrollment was associated with frailty. Frail patients had higher NRM than nonfrail patients (P < .001), with a 10-year cumulative incidence of 41% (95% confidence interval [CI], 32% to 49%) versus 22% (95% CI, 17% to 28%). Reciprocally, frailty also was associated with a significantly lower OS (P < .001), with a 10-year OS of 43% (95% CI, 35% to 53%) in frail patients versus 63% (95% CI, 57% to 69%) in nonfrail patients. In multivariable analysis that included the individual domains of frailty, weakness, low physical activity, and slow walking speed were associated with survival. Frail patients also had worse scores on various measures of patient-reported outcomes, including the Short Form (SF)-36, the Lee Symptom Scale, and the trial outcome of the Functional Assessment of Cancer Therapy-Bone Marrow Transplantation (FACT-BMT) index score. Frail patients with cGVHD have significantly worse outcomes than nonfrail patients. Such clinical features as older age and lung and liver cGVHD are associated with frailty. Earlier clinical recognition of frailty in patients with cGVHD may prompt interventions to counteract frailty that could be beneficial for this population.

Frailty in chronic myeloid leukemia: evidence from 2016-2018 Nationwide Inpatient Sample of the US

BACKGROUND

Frailty is a marker of poor prognosis in older adults with hematologic malignancies and contributes to the severe vulnerability of the aging population to adverse health outcomes. This study aimed to determine the association between frailty and outcomes in hospitalized patients with chronic myeloid leukemia (CML).

METHODS

The International Classification of Diseases (ICD-10) identified data on hospitalized patients 20 years or older admitted with CML between 2016 and 2018 in the US National Inpatient Sample (NIS) database. The cohort was further divided into groups of patients with or without frailty. Logistic regression analysis was performed to determine associations between study variables and clinical outcomes. A stratified analysis of the association between frailty and in-hospital mortality by age group was also performed.

RESULTS

A total of 13,849 hospitalized patients with CML were included, 49.6% of whom had frailty. The mean age of the patients was 65.1 years, and 7,619 (56.2%) of them were male. Frailty was associated with nearly 4 times the risk of in-hospital mortality, 3 times the risk of unfavorable discharge, 3 times the risk of prolonged LOS,, and significantly more in total hospital costs. In addition, frailty was associated with a significantly increased risk of in-hospital mortality in all age subgroups (< 40 years, 40-59 years, and > 60 years) compared with no frailty.

CONCLUSIONS

Frailty strongly predicts poor clinical outcomes in US patients with CML.

An objective assessment in newly diagnosed multiple myeloma to avoid treatment complications and strengthen therapy adherence

In heterogeneous multiple myeloma (MM) patients treatment decisions are challenging. The hypothesis was that adaptation of treatment intensity (dose reduction [DR] vs. none) according to an objective risk score (revised-myeloma comorbidity index [R-MCI]) rather than physician judgement alone may improve therapy efficacy and avoid toxicities. We performed this study in 250 consecutive MM patients who underwent a prospective fitness assessment at our center, after having received induction protocols based on physicians' judgement. DR, serious adverse events (SAE), response, progression-free survival (PFS) and overall survival (OS) were compared in fitness (fit, intermediate-fit, frail), age (<60, ≥70 years [y]) and therapy intensity subgroups at baseline and follow-up. Fit and <60 y patients were mostly treated with full intensity, whereas frail and ≥70 y patients usually received DR. Hematological and non-hematological SAE were more frequently seen in frail versus ≥70 y patients. Dose adaptations were mainly necessary in frail patients. OS and PFS were similar in fit and intermediate-fit but significantly worse in frail patients (P=0.0245/P<0.0001), whereas in age-based subgroups, OS and PFS differences did not reach significance (P=0.1362/P=0.0569). Non-hematological SAE were another negative predictor for impaired OS and PFS (P=0.0054/P=0.0021). In the follow-up performed at a median of 11 months after the first fitness assessment, the R-MCI improved or remained stable in 90% versus deteriorated in only 10% of patients. In conclusion, separation by R-MCI/frailty-defined subgroups was superior to age-based subgroups and can be used to improve tailored treatment. Fitter patients benefit from intensive therapies, whereas frail patients bear a need for initial DR.

Is It Time to Integrate Frailty Assessment in Onconephrology?

Simple Summary

There are an increasing number of older people living with kidney cancer and/or cancer and kidney disease worldwide, sparking a wider discussion on the impact of frailty and the clinical significance of conducting frailty assessments for this patient population. We provide an update on the current evidence related to frailty assessment in onconephrology and identify areas where further research efforts are anticipated to address knowledge gaps within this topic.

Abstract

Onconephrology has emerged as a novel sub-specialty of nephrology dedicated to the intersection between the kidney and cancer. This intersection is broad and includes a number of important areas of focus, including concurrent chronic kidney disease (CKD) and cancer, acute kidney complications of cancer, and cancer-treatment-induced nephrotoxicity. The importance of onconephrology is even more evident when considering the global growth in the population of older adults, many of whom are living with some degree of frailty. Furthermore, a considerable proportion of older adults have CKD (some of whom eventually progress to kidney failure) and are at high risk of developing solid tumour and hematologic malignancies. Specific to kidney disease, the association between frailty status and kidney disease has been explored in depth, and tools to capture frailty can be used to guide the management and prognostication of older adults living with kidney failure. Whilst there is emerging data regarding the assessment and impact of frailty in onconephrology, there remains a relative paucity of knowledge within this topic. In this article, we evaluate the definition and operationalization of frailty and discuss the significance of frailty within onconephrology. We review evidence on current approaches to assessing frailty in onconephrology and discuss potential developments and future directions regarding the utilization of frailty in this patient population. A greater awareness of the intersections and interactions between frailty and onconephrology and further efforts to integrate frailty assessment in onconephrology to optimize the delivery of realistic and goal-directed management strategies for patients is needed.

Impact of hematopoietic cell transplant frailty scale on transplant outcome in adults

This prospective study designs an HCT Frailty Scale to classify alloHCT candidates into groups of frail, pre-frail, and fit, and to be implemented in the first consultation at no additional cost. The present scale is composed of the following eight variables: Clinical Frailty Scale, Instrumental Activities of Daily Living, Timed Up and Go Test, Grip Strength, Self-Health Rated, Falls, Albumin, and C-Reactive Protein. The Frailty score of a patient is the weighted sum of scores for each item, with weights assigned according to the hazard ratios of a multivariable Cox proportional hazards model estimated and validated with data on OS as the dependent variable, and the scores of the eight variables as explanatory ones, from 298 adults split into training (n = 200) and validation (n = 98) sets. For clinical use, the scale scores were transformed into three categories: scale score ≤1: fit; 1<scale score ≤5.5: pre-frail; scale score >5.5 frail. The estimated probabilities of 1-year OS in each group of frailty, were, respectively: 83.7%, 48.5%, and 16.5% (p < 0.001). In the validation cohort, the respective values were 90.3%, 69.5%, and 46.2% (p < 0.001). Pending further external validations, the HCT Frailty Scale is a low cost-highly informative prognostic signal of outcomes at the pre-transplant stage.

Combining the HCT-CI, G8, and AML-Score for Fitness Evaluation of Elderly Patients with Acute Myeloid Leukemia: A Single Center Analysis

BACKGROUND

Accurate assessment of elderly acute myeloid leukemia (AML) patients is essential before intensive induction chemotherapy and subsequent allogeneic hematopoietic stem cell transplantation. In this context, we investigated the capacity of three scores for frailty prediction.

METHODS

At diagnosis, 197 patients were clinically evaluated for appropriate treatment intensity. In parallel and independently, the G8-score, the Hematopoietic Stem Cell Index (HCT-CI) and the AML-score for CR were determined for each patient and analyzed with respect to overall survival (OS).

RESULTS

The G8-score and the HCT-CI were able to significantly separate "fit" from "unfit" patients, <0.001 and p = 0.008. In univariate Cox models, the predictive role for OS was confirmed: for the G8-score (HR: 2.35, 95% CI 1.53-3.60, p < 0.001), the HCT-CI (HR: 1.91, 95% CI 1.17-3.11, p = 0.009) and the AML-score (HR: 5.59, 95% CI 2.04-15.31, p = 0.001), the latter was subsequently used to verify the cohort. In the multivariate Cox model, the results were confirmed for the G8- (HR: 2.03, p < 0.001) and AML-score (HR: 3.27, p = 0.001). Of interest, when combining the scores, their prediction capacity was significantly enhanced, p < 0.001.

CONCLUSIONS

The G8-, the HCTCI and the AML-score represent valid tools in the frailty assessment of elderly AML patients at diagnosis.

Combining a Frailty Index Based on Laboratory Data and Pneumonia Severity Assessments to Predict In-Hospital Outcomes in Older Adults with Community-Acquired Pneumonia

OBJECTIVES

Due to the increased morbidity, mortality, and cost of community-acquired pneumonia (CAP) in older people, strategies directed at improving disease evaluation and prevention are imperative. We independently compared the 30-day in-hospital mortality prediction ability of a frailty index based on laboratory data (FI-Lab) with that of the CURB-65 and the Pneumonia Severity Index (PSI) and then proposed combining them to further improve prediction efficiency.

DESIGN

Retrospective cohort study.

SETTING AND PARTICIPANTS

Patients aged ≥ 65 years (n = 2039) with CAP who were admitted to Jiangsu Provincial People's Hospital of Nanjing Medical University and Jiangsu Provincial Hospital of Chinese Medicine from January 2019 to June 2022.

MEASURES

The 29-item FI-Lab, PSI and, CURB-65 were administered at admission. We defined frailty by the cut-off value of the FI-Lab score (> 0.43). Multivariable logistic regression analysis, together with the calculation of the area under the receiver operating characteristic curve (ROC-AUC), was conducted to identify stratified risks and relationships between the three indices and 30-day mortality. Participants were divided into the following three groups based on age: 65-74 years, 75-84 years, and ≥ 85 years. Hazard ratios (HRs) and 95% confidence intervals (CIs) for mortality due to frailty were calculated.

RESULTS

A total of 495 participants ranging from 65 to 100 years of age were ultimately included and divided into age groups (65-74 years, n = 190, 38.4%; 75-84 years, n = 183, 37.0%; ≥ 85 years, n = 122, 24.6%). A total of 142 (28.7%) of the 495 patients were defined as having frailty. All three scores tested in this study were significantly associated with 30-day mortality in the total sample. The ORs were as follows: 1.06 (95% CI: 1.03-1.09, P < 0.001) and 2.33 (95% CI: 1.26-4.31, P = 0.007) for the FI-Lab when the score was treated as a continuous and categorical variable, respectively; 1.04 (95% CI: 1.02-1.05, P < 0.001) for the PSI; and 3.70 (95% CI: 2.48-5.50, P < 0.001) for the CURB-65. In the total sample, the ROC-AUCs were 0.783 (95% CI: 0.744-0.819) for the FI-Lab, 0.812 (95% CI: 0.775-0.845) for the PSI, and 0.799 (95% CI: 0.761-0.834) for the CURB-65 (P < 0.001). The ROC-AUC slightly improved when the FI-Lab was added to the PSI (AUC 0.850, 95% CI: 0.809-0.892, P = 0.031) and to the CURB-65 (AUC 0.839, 95% CI: 0.794-0.885, P = 0.002). Older patients with frailty showed a higher risk of in-hospital mortality, with an HR of 2.25 (95% CI: 1.14-3.58, P < 0.001).

CONCLUSION AND IMPLICATIONS

The FI-Lab seems to generate simple and readily available data, suggesting that it could be a useful complement to the CURB-65 and the PSI as effective predictors of 30-day mortality due to CAP in older populations.

Prognostication in myelodysplastic syndromes (neoplasms): Molecular risk stratification finally coming of age

Accurate risk prognostication is central to the management of myelodysplastic syndromes, given the widely heterogeneous clinical outcomes of these bone marrow failure disorders. Over the past decade, the rapidly expanding compendium of molecular lesions in myelodysplastic syndrome (MDS) has offered unprecedented insight into MDS pathobiology. Recently, molecular prognostic models such as the Molecular International Prognostic Scoring System (IPSS-M) have leveraged the wellspring of genetic data to improve upon traditional risk models such as the Revised IPSS (IPSS-R), but also added substantial complexity. In this review, we highlight early MDS prognostic models, the significant advancements in MDS genomics since then, and the recent advent of molecular based prognostic models. We conclude by discussing important opportunities and challenges in the management of MDS as we arrive at the molecular frontier.

The Influence of the Gut Microbiome in Paediatric Cancer Origin and Treatment

Knowledge of the complexity of the gut microbiota is expanding, and its importance in physiological processes and disease development is widely studied. The aim of this review is to present the most relevant and recent research on the associations between gut microbiota and oncologic disease. Recently, a number of associations between the gut microbiome and neoplasms—regarding tumorigenesis, prognosis and therapeutic efficacy—have been reported. The effects of the gut microbiome on these processes are via the direct and indirect immunomodulating effects of bacteria. Studies have been done mainly in adult populations, where its effect on immunomodulating therapies was unambiguous. In paediatric populations, however, due to the low number of cases and the complex therapeutic approaches, there have been only a few studies. Among them, children with acute lymphoblastic leukaemia were mainly involved. Significant alterations in the abundance of certain bacteria were associated with altered therapeutic responses. Regarding solid tumours, studies with low case numbers have been reported; no significant discoveries have been described so far. In the future, studies with larger cohorts are needed in order to better understand the associations between bacteria and neoplasms and to improve prognosis in the paediatric oncologic population.

Association of IMWG frailty score with health-related quality of life profile of patients with relapsed refractory multiple myeloma in Italy and the UK: a GIMEMA, multicentre, cross-sectional study

BACKGROUND

The clinical management of patients with relapsed or refractory multiple myeloma is challenging and there is a paucity of tools to help clinicians make more informed decisions for the most suitable treatment options. We aimed to investigate the clinical utility of the International Myeloma Working Group (IMWG) frailty score in the setting of relapsed or refractory multiple myeloma, by examining its ability to capture different patient-reported health-related quality of life profiles.

METHODS

We did a cross-sectional analysis of a prospective observational study of patients with relapsed or refractory multiple myeloma in Italy and the UK (30 hospitals across northern, central, and southern Italy, and one hospital in London, UK). Inclusion criteria were age 18 years or older and patients who had received at least one previous line of therapy and no more than five lines. Participants were excluded if they had a psychiatric disorder or major cognitive dysfunction, or any grade 3 or higher adverse event within 2 weeks before study entry. On study initiation, physicians had to assess frailty according to the IMWG criteria, which included the Charlson Comorbidity Index, the Katz Activity of Daily Living, and the Lawton Instrumental Activities of Daily Living. Patients were asked to complete patient-reported outcome measures, including the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire-Core30 (EORTC QLQ-C30) and its validated multiple myeloma module (QLQ-MY20). A multivariable linear regression model was used to assess the mean differences in health-related quality of life scores between frailty groups to account for key potential confounding factors.

FINDINGS

Overall, between Nov 13, 2017, and Nov 15, 2021, 415 patients with relapsed or refractory multiple myeloma, with a median age of 69·8 years (IQR 62·8-75·2) were enrolled. The median time since diagnosis was 4·4 years (IQR 2·5-7·1) and most patients (351 [85%]) had received at least two previous lines of therapy. According to the IMWG frailty score, 200 (48%) were classified as fit, 112 (27%) were classified as intermediate-fit, and 103 (25%) patients were classified as frail. Each frailty group was associated with a distinct health-related quality of life profile, with most notable differences between fit and frail patients. The largest clinically meaningful adjusted differences between fit and frail patients by the EORTC QLQ-C30 questionnaire were observed for physical functioning (Δ=-19·0 [95% CI -25·6 to -12·5; p<0·0001), fatigue (Δ=16·7 [9·7 to 23·7]; p<0·0001), insomnia (Δ=13·4 [4·1 to 22·6]; p=0·0047), and dyspnoea (Δ=12·5 [4·6 to 20·4]; p=0·0021). The most prevalent clinically important symptom in the overall population was pain; however, its prevalence varied between IMWG frailty groups at 70·9% in frail patients, 55·9% in intermediate-fit patients, and 50·5% in fit patients.

INTERPRETATION

Our findings show the clinical utility of the IMWG frailty score in the setting of relapsed or refractory multiple myeloma, in helping to distinguish between groups of patients with distinct health-related quality of life profiles. Further research is needed to examine the value of patient-reported outcome data in improving assessment of frailty in the setting of relapsed or refractory multiple myeloma.

What do hematology residents know about caring for older adults with cancer? A National Survey of Canadian hematology residents' knowledge and interests

INTRODUCTION

As the Canadian population ages, older adults comprise an increasing proportion of those diagnosed and treated for hematologic malignancies. A geriatric oncology curriculum has been recognized as a top priority in the care of older patients with cancer. It is not clear, however, whether hematology trainees receive training in geriatric oncology. We sought to understand residents' views and needs for a geriatric oncology curriculum during hematology residency in Canada.

MATERIALS AND METHODS

We conducted a cross-sectional needs assessment of hematology trainees enrolled in a Canadian residency or advanced fellowship training program within hematology. The survey, which was piloted with three non-hematology residents to ensure user-friendliness, used a combination of Likert scale, multiple-choice, and open-ended questions. The survey comprised three sections: (1) demographic data, (2) current state of geriatric oncology training (amount, content) and (3) attitudes towards learning about geriatric oncology and preferred curriculum components and identified needs. The survey was administered by the study team and distributed electronically to program directors in June 2020. The program directors were asked to forward the survey to trainees registered within their Division of Hematology. Data were analyzed descriptively.

RESULTS

Twenty-nine hematology residents participated (41.4% estimated response rate). Most respondents had not received geriatric oncology teaching (58.6%, n = 17) and have never been taught about geriatric oncology assessment tools (72.4%, n = 21) during hematology residency. Most respondents felt that their program should deliver a geriatric oncology curriculum (96.6%, n = 28). Respondents were most interested in learning about use of geriatric assessment tools for pre-treatment chemotherapy decision-making (86.2%, n = 25), prediction of chemotherapy toxicity (82.8%, n = 24), and to facilitate conversations regarding treatment initiation, continuation, or termination (79.3%, n = 23).

DISCUSSION

Our study highlights the paucity of geriatric oncology training in hematology residency training programs. Our results highlight both the need and interest for a future dedicated geriatric oncology curriculum integrated into hematology training and provide guidance about which topics are most valued by trainees.

Associations of clinical and circulating metabolic biomarkers with low physical fitness and function in adults with chronic lymphocytic leukemia

Many patients with chronic lymphocytic leukemia (CLL) experience physical dysfunction and low overall fitness. It remains unknown what factors drive CLL physical dysfunction. We assessed physical function and metabolic lipoprotein panels in 106 patients with CLL. In univariate analyses of clinical factors, a longer time since diagnosis was associated with a higher likelihood of dysfunctional aerobic fitness (OR = 3.56, 95% CI: 1.37–9.22; p = 0.002) and physical performance (SPPB: OR = 2.03, 95% CI: 1.20–3.44; p = 0.004). Having received treatment was associated with a higher likelihood of dysfunctional aerobic fitness (OR = 1.57, 95% CI: 1.02–2.40; p = 0.036), SPPB (OR = 1.85, 95% CI: 1.13–3.03; p = 0.011) and grip strength (OR = 1.67, 95% CI: 1.10–2.55; p = 0.015). We found that several small HDL particle parameters, higher levels of citrate (OR = 2.01, 95% CI: 1.22–3.31; p = 0.030), and lower levels of hemoglobin (OR = 0.50, 95% CI: 0.31–0.82; p = 0.030) were associated with a higher likelihood of dysfunctional aerobic fitness. Multivariable least absolute shrinkage and selection operator (LASSO)-penalized regression analyses using variable importance measures (VIM) showed that 7.8-nm HDL particles (VIM = 1.000) and total HDL particle levels (VIM = 1.000) were more informative than clinical measures for the odds of dysfunctional aerobic fitness and 6-min walk functional fitness, respectively, while 10.3-nm HDL particles (VIM = 0.383) were more informative for grip strength. Time since diagnosis (VIM = 0.680) and having received treatment (VIM = 0.490) were more informative than lipoprotein measures for the odds of having dysfunctional SPPB. Taken together, we establish significant relationships between clinical and metabolic factors and physical characteristics that might prompt early use of ancillary support services.

Randomized controlled trial of geriatric consultation versus standard care in older adults with hematologic malignancies

We conducted a randomized controlled trial in older adults with hematologic malignancies to determine the impact of geriatrician consultation embedded in our oncology clinic alongside standard care. From February 2015 to May 2018, transplant-ineligible patients aged ≥75 years who presented for initial consultation for lymphoma, leukemia, or multiple myeloma at Dana-Farber Cancer Institute (Boston, MA, USA) were eligible. Pre-frail and frail patients, classified based on phenotypic and deficit-accumulation approaches, were randomized to receive either standard oncologic care with or without consultation with a geriatrician. The primary outcome was 1-year overall survival. Secondary outcomes included unplanned care utilization within 6 months of follow-up and documented end-of-life (EOL) goals-of-care discussions. Clinicians were surveyed as to their impressions of geriatric consultation. One hundred sixty patients were randomized to either geriatric consultation plus standard care (n=60) or standard care alone (n=100). The median age of the patients was 80.4 years (standard deviation = 4.2). Of those randomized to geriatric consultation, 48 (80%) completed at least one visit with a geriatrician. Consultation did not improve survival at 1 year compared to standard care (difference: 2.9%, 95% confidence interval: -9.5% to 15.2%, P=0.65), and did not significantly reduce the incidence of emergency department visits, hospital admissions, or days in hospital. Consultation did improve the odds of having EOL goals-of-care discussions (odds ratio = 3.12, 95% confidence interval: 1.03 to 9.41) and was valued by surveyed hematologic-oncology clinicians, with 62.9%-88.2% of them rating consultation as useful in the management of several geriatric domains.

Rg1 Protects Hematopoietic Stem Cells from LiCl-Induced Oxidative Stress via Wnt Signaling Pathway

Background

Ginsenoside Rg1 is a major component of ginseng with antioxidative and antiaging effects, which is a traditional Chinese medicine. In this study, we investigated the potential spillover and mechanism of action of Rg1 on LiCl-driven hematopoietic stem cell aging.

Results

Collect the purified Sca-1⁺ hematopoietic cells for differentiation ability detection and biochemical and molecular labeling. The experiment found that Rg1 plays an antiaging role in reversing the SA-β-gal staining associated with LiCl-induced hematopoietic stem cell senescence, the increase in p53 and p21 proteins, and sustained DNA damage. At the same time, Rg1 protects hematopoietic cells from the reduced differentiation ability caused by LiCl. In addition, Rg1 increased the excessive inhibition of intracellular GSK-3β protein, resulting in the maintenance of β-catenin protein levels in hematopoietic cells after LiCl treatment. Then, the target gene level of β-catenin can be maintained.

Conclusions

Rg1 exerts the pharmacological effect of maintaining the activity of GSK-3β in Sca-1⁺ hematopoietic cells, enhances the antioxidant potential of cells, improves the redox homeostasis, and thus protects cells from the decline in differentiation ability caused by aging. This study provides a potential therapeutic strategy to reduce stem cell pool failure caused by chronic oxidative damage to hematopoietic stem cells.

Hematopoiesis, Inflammation and Aging-The Biological Background and Clinical Impact of Anemia and Increased C-Reactive Protein Levels on Elderly Individuals

Anemia and systemic signs of inflammation are common in elderly individuals and are associated with decreased survival. The common biological context for these two states is then the hallmarks of aging, i.e., genomic instability, telomere shortening, epigenetic alterations, loss of proteostasis, deregulated nutrient sensing, mitochondrial dysfunction, cellular senescence, stem cell exhaustion and altered intercellular communication. Such aging-associated alterations of hematopoietic stem cells are probably caused by complex mechanisms and depend on both the aging of hematopoietic (stem) cells and on the supporting stromal cells. The function of inflammatory or immunocompetent cells is also altered by aging. The intracellular signaling initiated by soluble proinflammatory mediators (e.g., IL1, IL6 and TNFα) is altered during aging and contributes to the development of both the inhibition of erythropoiesis with anemia as well as to the development of the acute-phase reaction as a systemic sign of inflammation with increased CRP levels. Both anemia and increased CRP levels are associated with decreased overall survival and increased cardiovascular mortality. The handling of elderly patients with inflammation and/or anemia should in our opinion be individualized; all of them should have a limited evaluation with regard to the cause of the abnormalities, but the extent of additional and especially invasive diagnostic evaluation should be based on an overall clinical evaluation and the possible therapeutic consequences.

Geriatric assessment predicts non-fatal toxicities and survival for intensively treated older adults with AML

Given a few prospective studies with conflicting results, we investigated the prognostic value of multi-parameter geriatric assessment (GA) domains on tolerance and outcomes after intensive chemotherapy in older adults with acute myeloid leukemia (AML). Newly diagnosed AML aged over 60 years who received intensive chemotherapy consisting of cytarabine and idarubicin (n=105) were enrolled prospectively. Pretreatment GA included evaluations for social and nutritional support, cognition, depression, distress, and physical function. The median age was 64 years (range, 60-75), and 93% had an Eastern Cooperative Oncology Group score <2. Between 32.4% and 69.5% of patients met the criteria for impairment for each domain of GA. Physical impairment by the Short Physical Performance Battery (SPPB) and cognitive dysfunction by the Mini-Mental State Examination in the Korean version of the CERAD Assessment Packet (MMSE-KC) were significantly associated with non-fatal toxicities, including grade III-IV infections (SPPB, P=0.024; MMSE-KC, P=0.044), acute renal failure (SPPB, P=0.013), and/or prolonged hospitalization (³40 days) during induction chemotherapy (MMSE-KC, P=0.005). Reduced physical function by SPPB and depressive symptoms by the Korean version of the short form of geriatric depression scales (SGDS-K) were significantly associated with inferior survival (SPPB, P=0.027; SGDS-K, P=0.048). Gait speed or sit-and-stand speed was the single powerful tool to predict survival outcomes. Notably, the addition of SPPB and SGDS-K, gait speed and SGDS-K, or sit-and-stand speed and SGDS-K significantly improved the power of existing survival prediction models. In conclusion, GA improved risk stratification for treatment decisions and may inform interventions to improve outcomes for older adults with AML. This study was registered at the Clinical Research Information Service (KCT0002172).

Electronic FRAIL score as a predictor of treatment outcomes in older patients with diffuse large B-cell lymphoma

INTRODUCTION

Frailty is a significant risk factor for poor outcomes among older patients with diffuse large B-cell lymphoma (DLBCL). We present an automatically derived electronic frailty screening tool (FRAIL score) as a predictor of patient outcomes.

METHODS

Patients aged 70 or over who received R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, prednisone) chemotherapy for DLBCL between 2010 and ` were retrospectively assessed for their FRAIL scores. Measured treatment outcomes included overall survival (OS), progression-free survival (PFS), and treatment-limiting toxicity from chemotherapy.

RESULTS

A total of 96 patients were analysed. When stratified by FRAIL score, the estimated 5-year PFS was 58%, 48% and, 0% for those with scores of 0-1, 2, and 3-5, respectively (p = 0.012). Similarly, the estimated 5-year OS for these respective groups was 60%, 60% and 0% (p = 0.010). Patients with a FRAIL score of 3-5 were also more likely than those with a score of 0-1 to need dose reduction or treatment delay due to toxicity (odds ratio [OR] 12.5, 95% confidence interval [CI] 10.42-109.72) and less likely to complete the six planned cycles of treatment (OR 0.14, 95% CI 0.03-0.77).

CONCLUSION

The FRAIL score is independently predictive of OS, PFS, and treatment-related toxicity in older patients with DLBCL receiving R-CHOP chemotherapy. Once implemented, it provides a quick and accessible method to stratify disease and treatment-related risk among these patients.

Integration of a Geriatric Assessment With Intervention in the Care of Older Adults With Hematologic Malignancies

The incidence of hematologic malignancies (HMs) is highest in the seventh decade of life and coincides with increasing occult, age-related vulnerabilities. Identification of frailty is useful in prognostication and treatment decision-making for older adults with HMs. This real-world analysis describes 311 older adults with HMs evaluated in a multidisciplinary oncogeriatric clinic. The accumulation of geriatric conditions [1-unit increase, hazards ratio (HR) = 1.13, 95% CI 1.00-1.27, p = 0.04] and frailty assessed by the Rockwood Clinical Frailty Scale (CFS, mild/moderate/severe frailty vs. very fit/well, HR = 2.59, 95% CI 1.41-4.78, p = 0.002) were predictive of worse overall survival. In multivariate analysis, HM type [acute leukemia, HR = 3.84, 95% CI 1.60-9.22, p = 0.003; myelodysplastic syndrome (MDS)/myeloproliferative neoplasm (MPN)/bone marrow failure, HR = 2.65, 95% CI 1.10-6.35, p = 0.03], age (per 5-year increase, HR = 1.46, 95% CI 1.21-1.76, p < 0.001), hemoglobin (per 1 g/dl decrease, HR = 1.21, 95% CI 1.05-1.40, p = 0.009), deficit in activities of daily living (HR = 2.20, 95% CI 1.11-4.34, p = 0.02), and Mini Nutrition Assessment score (at-risk of malnutrition vs. normal, HR = 2.00, 95% CI 1.07-3.73, p = 0.03) were independently associated with risk of death. The most commonly prescribed geriatric interventions were in the domains of audiology (56%) and pharmacy (54%). The Rockwood CFS correlated with prescribed interventions in nutrition (p = 0.01) and physical function (p < 0.001) domains. Geriatric assessment with geriatric intervention can be practically integrated into the routine care of older adults with HMs.

A comprehensive approach to therapy of haematological malignancies in older patients

Haematological malignancies are a heterogeneous group of diseases with diverse incidence. In Europe, the median age at diagnosis across all disease entities is 69 years. Incidence generally increases with age, reaching a maximum at 75-99 years, with the notable exceptions of Hodgkin lymphoma and acute lymphocytic leukaemia. Overall survival for patients aged 75 years and older with haematological malignancies is generally poor, particularly for acute leukaemias. Understanding the heterogeneity in outcomes for haematological malignancies, treatment challenges, and management of frailty and comorbidities among older patients could help physicians to better address the haematological cancer burden and mortality in ageing populations. The aim of this Series paper is to provide an updated overview of the knowledge accumulated over the past decade regarding treatment options and broader management considerations in older adults with haematological malignancies, focusing on the most common entities encountered across lymphoma, acute leukaemia, chronic leukaemia, and multiple myeloma disease categories. Future strategies, such as increasing enrolment rates of older adults in clinical trials and incorporating patient-reported outcome measurements in daily clinical practice, will assist in providing more individualised health care.

Association of Treatment Intensity With Survival in Older Patients With Hodgkin Lymphoma

IMPORTANCE

Hodgkin lymphoma is an aggressive blood cancer that is highly curable in younger patients who receive multiagent chemotherapy. Worse survival in older patients may reflect less-aggressive treatment, competing risks of death, or different disease biological factors.

OBJECTIVE

To examine the association between treatment intensity and cause-specific mortality among older adults with Hodgkin lymphoma.

DESIGN, SETTING, AND PARTICIPANTS

This was a population-based cohort study of patients aged 65 years or older with Medicare Part A and B fee-for-service coverage who received a diagnosis of Hodgkin lymphoma from 2000 to 2013. The association between treatment intensity and cause-specific mortality was estimated separately for early-stage and advanced-stage disease with Cox proportional hazards models. Multivariable adjustment and propensity score weighting helped control for confounding. Data are from the 1999 to 2016 Surveillance, Epidemiology, and End Results Medicare database. Data analysis was performed from April 2020 to June 2021.

EXPOSURES

First-line treatment categorized as (1) full chemotherapy regimen, (2) partial chemotherapy regimen, (3) single chemotherapy agent or radiotherapy, or (4) no treatment.

MAIN OUTCOMES AND MEASURES

The main outcome was 3-year Hodgkin lymphoma-specific and other-cause mortality.

RESULTS

Among 2686 patients (mean [SD] age, 75.7 [6.9] years; 1333 men [50%]), 1307 had early-stage disease and 1379 had advanced-stage disease. For Hodgkin lymphoma-specific mortality in patients with early-stage disease, hazard ratios (HRs) were higher for partial regimens (HR, 1.77; 95% CI, 1.22-2.57) or no treatment (HR, 1.91; 95% CI, 1.31-2.79) than for full regimens; there was no difference between single-agent chemotherapy or radiotherapy and full regimens. For other-cause mortality in patients with early-stage disease, HRs were higher for partial regimens (HR, 1.69; 95% CI, 1.18-2.44), single-agent chemotherapy or radiotherapy (HR, 1.62; 95% CI, 1.13-2.33), or no treatment (HR, 2.71; 95% CI, 1.95-3.78) than for full regimens. For Hodgkin lymphoma-specific mortality in patients with advanced-stage disease, HRs were higher for partial regimens (HR, 3.26; 95% CI, 2.44-4.35), single-agent chemotherapy or radiotherapy (HR, 2.85; 95% CI, 1.98-4.11), or no treatment (HR, 4.06; 95% CI, 3.06-5.37) than for full regimens. For other-cause mortality in patients with advanced-stage disease, HRs were higher for partial regimens (HR, 1.76; 95% CI, 1.32-2.33), single-agent chemotherapy or radiotherapy (HR, 1.65; 95% CI, 1.15-2.37), or no treatment (HR, 2.24; 95% CI, 1.71-2.94) than for full regimens.

CONCLUSIONS AND RELEVANCE

This cohort study found variability in the magnitude of the association between treatment intensity and mortality by stage and cause-specific mortality, possibly reflecting competing risks of death. However, full chemotherapy regimens were associated with lower mortality and could be considered for older adults who can tolerate them.
