Prevalence, severity and correlates of fatigue in newly diagnosed patients with myelodysplastic syndromes

Toward a more patient-centered drug development process in clinical trials for patients with myelodysplastic syndromes/neoplasms (MDS): Practical considerations from the International Consortium for MDS (icMDS)

Notable treatment advances have been made in recent years for patients with myelodysplastic syndromes/neoplasms (MDS), and several new drugs are under development. For example, the emerging availability of oral MDS therapies holds the promise of improving patients' health-related quality of life (HRQoL). Within this rapidly evolving landscape, the inclusion of HRQoL and other patient-reported outcomes (PROs) is critical to inform the benefit/risk assessment of new therapies or to assess whether patients live longer and better, for what will likely remain a largely incurable disease. We provide practical considerations to support investigators in generating high-quality PRO data in future MDS trials. We first describe several challenges that are to be thoughtfully considered when designing an MDS-focused clinical trial with a PRO endpoint. We then discuss aspects related to the design of the study, including PRO assessment strategies. We also discuss statistical approaches illustrating the potential value of time-to-event analyses and their implications within the estimand framework. Finally, based on a literature review of MDS randomized controlled trials with a PRO endpoint, we note the PRO items that deserve special attention when reporting future MDS trial results. We hope these practical considerations will facilitate the generation of rigorous PRO data that can robustly inform MDS patient care and support treatment decision-making for this patient population.

Latest Insights and Therapeutic Advances in Myelodysplastic Neoplasms

Myelodysplastic syndromes/neoplasms (MDSs) encompass a range of hematopoietic malignancies, commonly affecting elderly individuals. Molecular alterations in the hematopoietic stem cell compartment drive disease pathogenesis. Recent advancements in genomic profiling have provided valuable insights into the biological underpinnings of MDSs and have expanded therapeutic options, particularly for specific molecularly defined subgroups. This review highlights the diagnostic principles, classification updates, prognostic stratification systems, and novel treatments, which could inform future clinical trials and enhance the management of adult MDS patients, particularly for specific molecularly defined subgroups.

Paroxysmal nocturnal hemoglobinuria: Review of the patient experience and treatment landscape

Paroxysmal nocturnal hemoglobinuria (PNH) is a rare disorder caused by complement-mediated hemolysis and thrombosis through the alternative pathway. The most common symptom of PNH is fatigue due to chronic anemia, which can negatively impact quality of life (QoL) and affect overall well-being. The currently approved therapies for PNH significantly limit intravascular hemolysis (IVH) and reduce the risk of thrombosis; however, they are associated with an infusion schedule that can become burdensome, and not all patients experience complete disease control. Several new complement inhibitors are in development that address the need for convenient routes of administration and aim to provide better disease control. With the variety of new treatment options on the horizon, hematologic markers as well as QoL concerns, patient opinion, and lifestyle factors should be considered to choose the optimal PNH treatment for each specific patient.

The experience of patients with hematological malignancy in their terminal stage: a phenomenological study from Jordan's perspective

BACKGROUND

Patients diagnosed with hematological malignancies residing in low-middle-income countries undergo significant physical and psychological stressors. Despite this, only 16% of them receive proper care during the terminal stages. It is therefore crucial to gain insight into the unique experiences of this population.

AIM

To have a better understanding of the needs and experiences of adult patients with advanced hematological malignancy by exploring their perspectives.

METHODS

A qualitative interpretive design was employed to collect and analyze data using a phenomenological approach. The study involved in-depth interviews with ten participants aged between 49 and 65 years, utilizing a semi-structured approach.

RESULTS

Two primary themes emerged from the participants' experiences of reaching the terminal stage of illness: "Pain, Suffering, and Distress" and "Spiritual Coping." The first theme encompassed physical and emotional pain, suffering, and distress, while the second theme was centered on the participants' spiritual coping mechanisms. These coping mechanisms included seeking comfort in religious practices, relying on spiritual support from family and friends, and finding solace in their beliefs and faith.

CONCLUSION

Patients with hematological malignancies in the terminal stages of their disease experience severe pain, considerable physical and psychosocial suffering, and spiritual distress. While they require support to cope with their daily struggles, their experiences often go unnoticed, leading to disappointment and loss of dignity. Patients mainly rely on their spirituality to cope with their situations. Healthcare providers must acknowledge these patients' needs and provide more holistic and effective care.

Fatigue in newly diagnosed acute myeloid leukaemia: general population comparison and predictive factors

OBJECTIVES

This study compared the burden of fatigue between treatment-naïve patients with newly diagnosed acute myeloid leukaemia (AML) and the general population and investigated patient factors associated with fatigue severity.

METHODS

Pretreatment patient-reported fatigue was assessed with the Functional Assessment of Chronic Illness Therapy-Fatigue questionnaire in a sample of 463 newly diagnosed patients with AML who were enrolled in a clinical trial. Multivariable linear regression models were used to estimate the adjusted mean differences in fatigue between patients with AML and adults from the general population (n=847) by AML disease risk categories. A clinically meaningful difference in fatigue was defined as ≥3 points. Univariable and multivariable linear regression models were used to identify sociodemographic, clinical and molecular correlates of worse fatigue in patients with AML.

RESULTS

Patients with AML reported adjusted mean fatigue scores that were 7.5 points worse than the general population (95% CI -8.6 to -6.4, p<0.001). Across AML disease risk categories, adjusted mean differences in fatigue compared with the general population ranged from 6.7 points worse (patients with favourable risk: 95% CI -8.6 to -4.8, p<0.001) to 8.9 points worse (patients with poor risk, 95% CI -10.5 to -7.2, p<0.001). Overall, 91% of patients with AML reported fatigue that was equal to or worse than the general population's median fatigue score. Higher pretreatment fatigue was independently associated with female sex, WHO performance status ≥1 and lower platelet levels.

CONCLUSIONS

Patients with newly diagnosed AML reported worse fatigue than the general population, and mean differences exceeded twice the threshold for clinical significance. Our findings may help to identify patients with AML most likely to benefit from supportive care interventions to reduce fatigue.

Determinants of low health-related quality of life in patients with myelodysplastic syndromes: EUMDS Registry study

Patients with myelodysplastic syndromes (MDS) frequently experience a significant symptom burden, which reduces health-related quality of life (HRQoL). We aimed to identify determinants of low HRQoL in patients recently diagnosed with MDS, for guiding early intervention strategies. We evaluated longitudinal data in 2205 patients with MDS during their first year after diagnosis. Median values of EQ-5D 3-level (EQ-5D-3L) index (0.78) and visual analog scale (VAS) score (0.70) were used as thresholds for low HRQoL. In addition, the 5 dimensions of EQ-5D-3L were analyzed for impairments (any level vs "no problem" category). After multiple imputation of missing values, we used generalized estimating equations (GEE) to estimate odds ratios (OR) for univariable determinant screening (P < .15), and to subsequently derive multivariable models for low HRQoL with 95% confidence intervals (CI). Multivariable GEE analysis showed the following independent determinants (OR, 95% CI) for low EQ-5D index: increased age (60-75 years: 1.33, 1.01-1.75; >75: 1.84, 1.39-2.45), female sex (1.70, 1.43-2.03), high serum ferritin level (≥1000 vs ≤300 μg/L: 1.41, 1.06-1.87), comorbidity burden (per unit: 1.11, 1.02-1.20), and reduced Karnofsky performance status (KPS, per 10 units: 0.62, 0.58-0.67). For low VAS score, additional determinants were transfusion dependence (1.53, 1.03-2.29), low hemoglobin <10 g/dL (1.34, 1.12-1.61), and high body mass index (≥30 vs 23-29.9 kg/m2: 1.26, 1.02-1.57). Sex, KPS, comorbidity burden, hemoglobin count, and transfusion burden were determinants for all EQ-5D dimensions. Low HRQoL is determined by multiple factors, which should be considered in the management and shared decision making of patients with MDS. This trial was registered at www.clinicaltrials.gov as #NCT00600860.

Update on Prevalence of Pain in Patients with Cancer 2022: A Systematic Literature Review and Meta-Analysis

Experiencing pain and insufficient relief can be devastating and negatively affect a patient's quality of life. Developments in oncology such as new treatments and adjusted pain management guidelines may have influenced the prevalence of cancer pain and severity in patients. This review aims to provide an overview of the prevalence and severity of pain in cancer patients in the 2014-2021 literature period. A systematic literature search was performed using the databases PubMed, Embase, CINAHL, and Cochrane. Titles and abstracts were screened, and full texts were evaluated and assessed on methodological quality. A meta-analysis was performed on the pooled prevalence and severity rates. A meta-regression analysis was used to explore differences between treatment groups. We identified 10,637 studies, of which 444 studies were included. The overall prevalence of pain was 44.5%. Moderate to severe pain was experienced by 30.6% of the patients, a lower proportion compared to previous research. Pain experienced by cancer survivors was significantly lower compared to most treatment groups. Our results imply that both the prevalence of pain and pain severity declined in the past decade. Increased attention to the assessment and management of pain might have fostered the decline in the prevalence and severity of pain.

Educational and Emotional Needs of Patients with Myelodysplastic Syndromes: An AI Analysis of Multi-Country Social Media

INTRODUCTION

Myelodysplastic syndromes (MDS) comprise a heterogeneous group of myeloid malignancies characterized by high symptom burden and limited treatment options. A central challenge to caring for patients with MDS is assessing their needs throughout the different phases of the disease. Patients and caregivers frequently consult online sources to address informational and emotional support needs.

METHODS

We conducted a social listening analysis of publicly available online forums to identify unmet needs of patients with MDS and their caregivers in the USA, the UK, Spain, Canada, France, and China. We used artificial intelligence (AI) and natural language processing (NLP) to group categories of posts into seven overarching motivations for online engagement (Clinical, Emotional, Treatments, Transplant, Education and Logistics, Physical, and Diet and Lifestyle).

RESULTS

Posts from the USA and China commonly discussed clinical topics such as MDS diagnosis, disease monitoring, and progression. Posts from Canada and France were frequently about treatments and treatment options. Emotional concerns were key drivers of posts from Canada, Spain, and the UK. Additionally, we also identified topics associated with negative language at key phases during the treatment experience where patients and caregivers exhibited increased online engagement, revealing educational and emotional support gaps at the time of diagnosis, when patients are deciding between treatment options, and when treatment options fail.

CONCLUSION

In this research, based on social media listening analyzed using AI and NLP, potential information gaps and unmet needs among patients with MDS were identified. Addressing these gaps through targeted patient education and guidance to emotional support options during these phases could reduce the disease burden and emotional distress experienced by patients with MDS.

Raising the standards of patient‐centered outcomes research in myelodysplastic syndromes: Clinical utility and validation of the subscales of the QUALMS from the MDS‐RIGHT project

BACKGROUND

Clinical decision-making for patients with myelodysplastic syndromes (MDS) is challenging, and both disease and treatment effects heavily impact health-related quality of life (HRQoL) of these patients. Therefore, disease-specific HRQoL measures can be critical to harness the patient voice in MDS research.

METHODS

We report a prospective international validation study of the Quality of Life in Myelodysplasia Scale (QUALMS) with a main focus on providing information on the psychometric characteristics of its three subscales: physical burden (QUALMS-P), emotional burden (QUALMS-E), and benefit finding (QUALMS-BF). The analysis is based on patients enrolled from three European countries and Israel, participating to the MDS-RIGHT Project. The scale structure and psychometric properties of the QUALMS were assessed.

RESULTS

Overall, 270 patients with a median age of 74 years were analyzed and the majority of them (60.3%) had a low MDS-Comorbidity Index score. Results of the confirmatory factor analysis supported the underlying scale structure of the QUALMS, which, in addition to a total score, includes three subscales: QUALMS-P, QUALMS-E, and the QUALMS-BF. The QUALMS-P exhibited the highest Cronbach's alpha coefficients. Discriminant validity analysis indicated good results with the QUALMS-P and QUALMS-E distinguishing between patients with different performance status, comorbidity, anemia, and transfusion dependency status. No floor and ceiling effects were observed. Responsiveness to change analysis supported the validity of the measure. Patients with a hemoglobin (Hb) level of <11 g/dL at study entry, who subsequently showed an improvement in their Hb levels, also reported a mean score change of 9 and 8 points (scales ranging between 0 and 100) in the expected direction of the QUALMS-E and QUALMS-P, respectively.

CONCLUSIONS

Our study provides additional validation data on the QUALMS from the international MDS-RIGHT Project. The use of this disease-specific HRQoL measure may contribute to raise quality standards of patient-centered outcomes research in MDS.

Myelodysplastic syndromes

Myelodysplastic syndromes (MDS) are a family of myeloid cancers with diverse genotypes and phenotypes characterized by ineffective haematopoiesis and risk of transformation to acute myeloid leukaemia (AML). Some epidemiological data indicate that MDS incidence is increasing in resource-rich regions but this is controversial. Most MDS cases are caused by randomly acquired somatic mutations. In some patients, the phenotype and/or genotype of MDS overlaps with that of bone marrow failure disorders such as aplastic anaemia, paroxysmal nocturnal haemoglobinuria (PNH) and AML. Prognostic systems, such as the revised International Prognostic Scoring System (IPSS-R), provide reasonably accurate predictions of survival at the population level. Therapeutic goals in individuals with lower-risk MDS include improving quality of life and minimizing erythrocyte and platelet transfusions. Therapeutic goals in people with higher-risk MDS include decreasing the risk of AML transformation and prolonging survival. Haematopoietic cell transplantation (HCT) can cure MDS, yet fewer than 10% of affected individuals receive this treatment. However, how, when and in which patients with HCT for MDS should be performed remains controversial, with some studies suggesting HCT is preferred in some individuals with higher-risk MDS. Advances in the understanding of MDS biology offer the prospect of new therapeutic approaches.

Patient Preferences for Benefits, Risks, and Administration Route of Hypomethylating Agents in Myelodysplastic Syndromes

INTRODUCTION/BACKGROUND

Therapy with infused or injected hypomethylating agents (HMAs) may lead to higher treatment administration burden (ie, local reaction, visit frequency and duration) vs. oral HMAs.   OBJECTIVES: To reveal preferences of US and Canadian patients with myelodysplastic syndromes (MDS) for HMAs' benefits, risks, and administration burden through an online discrete-choice experiment (DCE).

MATERIALS AND METHODS

Choice of DCE attributes and survey development were informed by literature review and interviews with clinicians, MDS patients, and caregivers serving as patient proxies, and patient advocacy groups (PAGs) representatives, including from AAMAC, AAMDS, and MDSF. DCE choice tasks were analyzed using random parameter logit models. Survey patients were recruited by the PAGs via their networks. To understand key preference drivers and how much patients were willing to trade between attributes, we calculated each attribute's relative attribute importance (RAI) and marginal rates of substitution.

RESULTS

One hundred eighty-four respondents (including 158 patients; mean age, 67.2 years; male, 50.5%; White, 50.5%; US residents, 88%) completed the survey. MDS risk was low (34.8%), high (30.9%), or unknown (34.2%). RAI (in decreasing order) was as follows: risk of AML (40%), fatigue level (33%), number of visits (12%), mode of administration (6%), visit duration (5%), and administration frequency (4%). Assuming the same risk of AML transformation or level of fatigue, most respondents (76.6%) were predicted to switch to an oral pill if it were available to them.

CONCLUSION

Given equivalent effectiveness across HMAs, patients' preferences for HMA administration method should be considered in treatment decision-making to minimize burden and facilitate adherence.

Chronic Fatigue Syndrome in Patients with Deteriorated Iron Metabolism

Fatigue is a common, non-specific symptom that often impairs patients’ quality of life. Even though fatigue may be the first symptom of many serious diseases, it is often underestimated due to its non-specific nature. Iron metabolism disorders are a prominent example of conditions where fatigue is a leading symptom. Whether it is an iron deficiency or overload, tiredness is one of the most common features. Despite significant progress in diagnosing and treating iron pathologies, the approach to chronic fatigue syndrome in such patients is not precisely determined. Our study aims to present the current state of knowledge on fatigue in patients with deteriorated iron metabolism.

Changes in hemoglobin and clinical outcomes drive improvements in fatigue, quality of life, and physical function in patients with paroxysmal nocturnal hemoglobinuria: post hoc analyses from the phase III PEGASUS study

Paroxysmal nocturnal hemoglobinuria (PNH) is a rare, chronic, acquired, hematologic, life-threatening disease characterized by thrombosis, impaired bone marrow function, and complement-mediated hemolysis. The PEGASUS phase III clinical trial demonstrated superiority of pegcetacoplan over eculizumab regarding improvements in hemoglobin levels in patients with suboptimal response to prior eculizumab treatment. The objective of this post hoc analysis was to compare the patient-reported outcome (PRO) response rates observed among PEGASUS participants and the relationships between their PRO scores with clinical and hematological parameters. Data from the 16-week randomized, controlled (1:1 to pegcetacoplan or eculizumab) period of the PEGASUS trial included comparisons of weekly PRO measurements taken using the Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F) scale and the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core-30 (EORTC QLQ-C30) scales. A clinically meaningful FACIT-F response was defined as an increase from baseline of ≥5 points. Convergent validity was assessed using conventional threshold correlations between FACIT-F, EORTC QLQ-C30, and laboratory parameters. A clinically meaningful improvement in FACIT-F score was seen in 72.2% of pegcetacoplan-treated patients compared to 22.9% of eculizumab-treated patients. At week 16, the FACIT-F total score correlated with hemoglobin levels (r=0.47, p< 0.0001), absolute reticulocyte count (r=−0.37, p<0.01), and indirect bilirubin levels (r=−0.25, p<0.05). Clinically meaningful improvements in pegcetacoplan-treated patients were also observed for multiple EORTC scales. Fatigue and other self-reported outcomes were correlated with clinically meaningful improvements in clinical and hematological parameters. Clinical trial registration: NCT03500549

Phase 1/2 study evaluating the safety and efficacy of DSP-7888 dosing emulsion in myelodysplastic syndromes

DSP-7888 is an immunotherapeutic cancer vaccine derived from the Wilms' tumor gene 1 (WT1) protein. This phase 1/2 open-label study evaluated the safety and efficacy of DSP-7888 dosing emulsion in patients with myelodysplastic syndromes (MDS). DSP-7888 was administered intradermally (3.5 or 10.5 mg) every 2 weeks for 6 months and then every 2-4 weeks until lack of benefit. Twelve patients were treated in phase 1 (3.5 mg, n = 6; 10.5 mg, n = 6), with no dose-limiting toxicities reported. Thus, the 10.5 mg dose was selected as the recommended phase 2 dose, and 35 patients were treated in phase 2. Forty-seven patients received ≥1 dose of the study drug and comprised the safety analysis set. The most common adverse drug reaction (ADR) was injection site reactions (ISR; 91.5%). Grade 3 ISR were common (58.8%) in phase 1 but occurred less frequently in 2 (22.9%) following implementation of risk minimization strategies. Other common ADR were pyrexia (10.6%) and febrile neutropenia (8.5%). In the efficacy analysis set, comprising patients with higher-risk MDS after azacitidine failure in phases 1 and 2 (n = 42), the disease control rate was 19.0%, and the median overall survival (OS) was 8.6 (90% confidence interval [CI], 6.8-10.3) months. Median OS was 10.0 (90% CI, 7.6-11.4) months in patients with a WT1-specific immune response (IR; n = 33) versus 4.1 (90% CI, 2.3-8.1) months in those without a WT1-specific IR (n = 9; P = .0034). The acceptable safety and clinical activity findings observed support the continued development of DSP-7888 dosing emulsion.

Early Palliative Care in Acute Myeloid Leukemia

Background: Several novel targeted therapies seem to improve the outcome of acute myeloid leukemia (AML) patients. Nonetheless, the 5-year survival rate remains below 40%, and the trajectory of the disease remains physically and emotionally challenging, with little time to make relevant decisions. For patients with advanced solid tumors, the integration of early palliative care (EPC) with standard oncologic care a few weeks after diagnosis has demonstrated several benefits. However, this model is underutilized in patients with hematologic malignancies. Methods: In this article, we analyze the palliative care (PC) needs of AML patients, examine the operational aspects of an integrated model, and review the evidence in favor of EPC integration in the AML course. Results: AML patients have a high burden of physical and psychological symptoms and high use of avoidant coping strategies. Emerging studies, including a phase III randomized controlled trial, have reported that EPC is feasible for inpatients and outpatients, improves quality of life (QoL), promotes adaptive coping, reduces psychological symptoms, and enhances the quality of end-of-life care. Conclusions: EPC should become the new standard of care for AML patients. However, this raises issues about the urgent development of adequate programs of education to increase timely access to PC.

Health-Related Quality of Life Assessment in Patients with Myelodysplastic Syndromes: Evidence from Randomized Clinical Trials

Myelodysplastic syndromes (MDS) are characterized by ineffective hematopoiesis and blood cytopenia with a variable risk of progression to acute myeloid leukemia. The main goal of therapy for the large majority of patients is to improve health-related quality of life (HRQoL). Its rigorous assessment is now recommended in international MDS guidelines. Our review provides an overview of HRQoL results from randomized controlled trials (RCTs) in MDS patients. The literature search undertaken in PubMed identified 10 RCTs with HRQoL endpoints (all secondary) published between August 2008 and September 2020. These RCTs have helped to better understand the impact of therapies from the patient perspective and have generated valuable information that can be used to further support clinical decisions. However, the number of RCTs in MDS patients, including HRQoL endpoints, is still low. Given the importance of symptom relief and HRQoL improvement in the treatment of MDS patients, the assessment of the patient perspective in future RCTs is highly recommended to keep expanding the knowledge of the impact of new MDS therapies.

Hemoglobin is a key determinant of quality of life before and during azacitidine-based therapy for myelodysplasia and low blast count acute myeloid leukemia

Myelodysplastic syndromes (MDS) have a major impact on quality of life (QoL). We performed a post hoc analysis of two multicenter trials of azacitidine-based disease-modifying therapy for patients with MDS and low blast count acute myeloid leukemia (AML), to identify factors associated with QoL. 231 patients were included (median age 70 years). At baseline, higher initial hemoglobin, but not neutrophil or platelet count, was associated with better global QoL and physical function (p < 0.001 and p = 0.001, respectively). During therapy, increase in hemoglobin was associated with improvement in QoL and physical function (p = 0.005 and p < 0.001, respectively). Lower initial hemoglobin was associated with higher dyspnea and fatigue scores (p < 0.001 and p = 0.001, respectively), and hemoglobin response was associated with improvement in dyspnea and fatigue (p < 0.001 for each). In patients with MDS and low blast count AML, hemoglobin level was strongly correlated with global QoL, physical functioning, dyspnea and fatigue, both before and during azacitidine-based therapy.

MyPal ADULT study protocol: a randomised clinical trial of the MyPal ePRO-based early palliative care system in adult patients with haematological malignancies

INTRODUCTION

The systematic collection of electronic patient-reported outcome (ePRO) in the routine care of patients with chronic haematological malignancies such as chronic lymphocytic leukaemia (CLL) and myelodysplasia syndromes (MDS) can constitute a very ambitious but worthwhile challenge. MyPal is a Horizon 2020 Research & Innovation Action aiming to meet this challenge and foster palliative care for patients with CLL or MDS by leveraging ePRO systems to adapt to the personal needs of patients and caregiver(s).

METHODS AND ANALYSIS

In this interventional randomised trial, 300 patients with CLL or MDS will be recruited across Europe. Patients will be randomly allocated to early palliative care using the MyPal system (n=150) versus standard care including general palliative care if needed (n=150). Patients in the experimental arm will be given access to the MyPal digital health platform which consists of purposely designed software available on smartphones and/or tablets. The platform entails different functionalities including physical and psychoemotional symptom reporting via regular questionnaire completion, spontaneous self-reporting, motivational messages, medication management and a personalised search engine for health information. Data on patients' activity (daily steps and sleep quality) will be automatically collected via wearable devices.

ETHICS AND DISSEMINATION

The integration of ePROs via mobile applications has raised ethical concerns regarding inclusion criteria, information provided to participants, free and voluntary consent, and respect for their autonomy. These have been carefully addressed by a multidisciplinary team. Data processing, dissemination and exploitation of the study findings will take place in full compliance with European Union data protection law. A participatory design was adopted in the development of the digital platform involving focus groups and discussions with patients to identify needs and preferences. The protocol was approved by the ethics committees of San Raffaele (8/2020), Thessaloniki 'George Papanikolaou' Hospital (849), Karolinska Institutet (20.10.2020), University General Hospital of Heraklion (07/15.4.2020) and University of Brno (01-120220/EK).

Core Set of Patient-Reported Outcomes for Myelodysplastic Syndromes - EUMDS Delphi Study in Patients and Hematologists

Systematically developed set of core PROs in MDS, involving patients and hematologists in a 2-round Delphi survey.

Core PROs will support unified outcome measurement and facilitate inclusion of reliable patient information in MDS disease care.

Patient-reported outcomes (PROs) are relevant and valuable end points in the care of patients with myelodysplastic syndromes (MDS). However, a consensus-based selection of PROs for MDS, derived by both patients and hematologists, is lacking. We aimed to develop a core set of PROs for patients with MDS as part of the prospective European LeukemiaNet MDS (EUMDS) Registry. According to international guidelines, candidate PROs were identified from a comprehensive literature search of MDS studies. Overall, 40 PROs were selected and evaluated in a two-round Delphi survey by 40 patients with MDS and 38 hematologists in the first round and 38 patients and 32 hematologists in the second round. Based on an agreement scale and predefined inclusion criteria, both patients and hematologists selected “general quality of life” as a core PRO. Hematologists also selected “transfusion-dependency burden” and “ability to work/activities of daily living” as core PROs. The second Delphi round increased PRO rating agreements. Statistically significant rating differences between patients and hematologists were observed for 28 PROs (Mann-Whitney U test; P < .05) in the first round and for 19 PROs in the second round, with “disease knowledge” and “confidence in health care services” rated notably higher by patients. The overall mean PRO ratings correlation between the 2 groups was moderate (Spearman’s rank correlation coefficient = 0.5; P < .05). This first consensus on a core set of PROs jointly developed by patients and hematologists forms the basis for patient-centered care in daily practice and clinical research.

The anemia-independent impact of myelodysplastic syndromes on health-related quality of life

Myelodysplastic syndromes (MDS) are in the majority of cases characterized by anemia. Both anemia and MDS per se may directly contribute to impairments in health-related quality of life (HRQoL). In this study, we aimed to investigate the anemia-independent impact of MDS on HRQoL. We evaluated participants (≥ 50 years) from the large population-based Lifelines cohort (N = 44,694, mean age 59.0 ± 7.4 years, 43.6% male) and the European MDS Registry (EUMDS) (N = 1538, mean age 73.4 ± 9.0 years, 63.0% male), which comprises a cohort of lower-risk MDS patients. To enable comparison concerning HRQoL, SF-36 scores measured in Lifelines were converted to EQ-5D-3L index (range 0–1) and dimension scores. Lower-risk MDS patients had significantly lower HRQoL than those from the Lifelines cohort, as illustrated in both the index score and in the five different dimensions. Multivariable linear regression analysis demonstrated that MDS had an adjusted total impact on the EQ-5D index score (B =  − 0.12, p < 0.001) and an anemia-independent “direct” impact (B =  − 0.10, p < 0.001). Multivariable logistic regression analysis revealed an anemia-independent impact of MDS in the dimension mobility, self-care, usual activities, and anxiety/depression (all except pain/discomfort). This study demonstrates that the major part of the negative impact of lower-risk MDS on HRQoL is not mediated via anemia. Thus, the therapeutic focus should include treatment strategies directed at underlying pathogenic mechanisms to improve HRQoL, rather than aiming predominantly at increasing hemoglobin levels.

Targeting health-related quality of life in patients with myelodysplastic syndromes - Current knowledge and lessons to be learned

Using a range of health-related quality of life (HRQoL) instruments, most - but not all - studies of myelodysplastic syndromes (MDS) have reported that lower hemoglobin levels and red blood cell transfusion dependency are associated with worse HRQoL. In addition, some MDS treatments may significantly improve HRQoL, particularly among those patients who respond to therapy; however, the majority of these studies were underpowered for this secondary endpoint. Furthermore, decreased HRQoL has been associated with worse survival outcomes, and HRQoL scores can be used to refine classical prognostic systems. Despite the subjective nature of HRQoL, the importance and validity of measuring it in trials and clinical practice are increasingly being recognized, but properly validated MDS-specific instruments are required. We describe what is currently known about HRQoL in patients with MDS, and the limitations of measuring HRQoL, and we provide some recommendations to improve the measurement of this outcome in future trials.

Epigenetics in a Spectrum of Myeloid Diseases and Its Exploitation for Therapy

Simple Summary

The genome is stored in the limited space of the nucleus in a highly condensed form. The regulation of this packaging contributes to determining the accessibility of genes and is important for cell function. Genes affecting the genome’s packaging are frequently mutated in bone marrow cells that give rise to the different types of blood cells. Here, we first discuss the molecular functions of these genes and their role in blood generation under healthy conditions. Then, we describe how their mutations relate to a subset of diseases including blood cancers. Finally, we provide an overview of the current efforts of using and developing drugs targeting these and related genes.

Abstract

Mutations in genes encoding chromatin regulators are early events contributing to developing asymptomatic clonal hematopoiesis of indeterminate potential and its frequent progression to myeloid diseases with increasing severity. We focus on the subset of myeloid diseases encompassing myelodysplastic syndromes and their transformation to secondary acute myeloid leukemia. We introduce the major concepts of chromatin regulation that provide the basis of epigenetic regulation. In greater detail, we discuss those chromatin regulators that are frequently mutated in myelodysplastic syndromes. We discuss their role in the epigenetic regulation of normal hematopoiesis and the consequence of their mutation. Finally, we provide an update on the drugs interfering with chromatin regulation approved or in development for myelodysplastic syndromes and acute myeloid leukemia.

Paroxysmal nocturnal hemoglobinuria: patient journey and burden of disease

Patients with paroxysmal nocturnal hemoglobinuria (PNH) often experience a lengthy path to diagnosis. Fewer than 40% of patients with PNH receive a diagnosis within 12 months of symptom onset, and 24% of all PNH diagnoses can take 5 years or longer. Diagnostic delay is a source of distress and can affect emotional well-being for patients with PNH. In PNH disease management, patients and care providers focus on risk of organ failure and mortality related to disease progression; nonetheless, patients' health-related quality of life (HRQOL) is largely affected by extensive treatment requirements and nonfatal complications of disease, such as fatigue. In particular, thrombosis is associated with significant impairments in physical and social functioning and global health status and significant fatigue. Among patients with anemia who are transfusion dependent, the burden of transfusion is considerable.

Chronic fatigue in myelodysplastic syndromes: Looking beyond anemia

Chronic fatigue is the most common and severe symptom in myelodysplastic syndromes (MDS) and has a strong negative association with health-related quality of life (HRQoL). Despite anemia being the most common objective manifestation of MDS, and the associated link between anemia and fatigue, evidence on treatments which temporarily mitigate anemia is equivocal regarding the effects on fatigue. Furthermore, previous work has found weak associations between anemia and chronic fatigue in MDS. As such, given that improving HRQoL is one of the primary treatment aims in MDS, further work is required to identify other potential contributors to chronic fatigue in these patients. In addition to anemia, MDS is associated with numerous other deviations in physiological homeostasis and has negative psychological consequences with links to chronic fatigue. Accordingly, the present review provides several potential aetiologic agents relevant to chronic fatigue in MDS which can be used to guide future research in this field.

High serum ferritin levels in newly diagnosed patients with myelodysplastic syndromes are associated with greater symptom severity

We examined the association between serum ferritin (SF) levels and patient-reported functional aspects and symptoms, as measured by the EORTC QLQ-C30, in newly diagnosed patients with myelodysplastic syndromes (MDS). Analysis was conducted on 497 MDS patients who were classified in two groups based on the SF value of 1000 ng/mL. Clinically relevant differences of patient-reported functional and symptom scales were evaluated and classified as small, medium and large, based on established thresholds. Multivariable linear regression analysis was performed to account for potential confounding factors. Patients with SF of ≥ 1000 ng/mL reported statistically significant and clinically relevant worse outcomes across various health domains. Dyspnea was the symptom indicating the largest difference and mean scores of patients with higher and lower SF levels were 40 and 24.3, respectively (p = 0.005), indicating a large clinically relevant difference (Δ = 15.7). Further research is needed to better understand the relationship between SF levels and specific health-related quality of life domains.

Development of a core outcome set for myelodysplastic syndromes - a Delphi study from the EUMDS Registry Group

Treatment options for myelodysplastic syndromes (MDS) vary widely, depending on the natural disease course and patient‐related factors. Comparison of treatment effectiveness is challenging as different endpoints have been included in clinical trials and outcome reporting. Our goal was to develop the first MDS core outcome set (MDS‐COS) defining a minimum set of outcomes that should be reported in future clinical studies. We performed a comprehensive systematic literature review among MDS studies to extract patient‐ and/or clinically relevant outcomes. Clinical experts from the European LeukemiaNet MDS (EUMDS) identified 26 potential MDS core outcomes and participated in a three‐round Delphi survey. After the first survey (56 experts), 15 outcomes met the inclusion criteria and one additional outcome was included. The second round (38 experts) resulted in six included outcomes. In the third round, a final check on plausibility and practicality of the six included outcomes and their definitions was performed. The final MDS‐COS includes: health‐related quality of life, treatment‐related mortality, overall survival, performance status, safety, and haematological improvement. This newly developed MDS‐COS represents the first minimum set of outcomes aiming to enhance comparability across future MDS studies and facilitate a better understanding of treatment effectiveness.

Early and sustained improvement in fatigue-related quality of life following red blood cell transfusion in outpatients

PURPOSE

Outpatients with hematologic disease often receive red cell transfusion to treat anemia and fatigue. The effect of transfusion on fatigue-related quality of life and how well this effect is sustained has not been quantified. The study aim was to describe the early and sustained impact over 4 weeks of red cells on patient-reported fatigue in outpatients age ≥ 50 receiving transfusion as routine clinical care.

METHODS

FACIT-Fatigue scale scores were measured pre-transfusion and at visits targeting 3, 7, and 28 days post-transfusion. Group-based trajectory modeling of patient fatigue scores by study day was used to identify the number of distinct trajectories (Groups), then longitudinal mixed effects modeling of fatigue scores was used to estimate group-specific mean improvements early after transfusion and between days 3 and 28 post-transfusion.

RESULTS

Four distinct fatigue score trajectory groups were identified and were found to be correlated with baseline fatigue scores (means 12, 26, 34, and 47 points). In the three groups with the lowest fatigue trajectories (indicating greater fatigue), improvements in fatigue early after transfusion achieved the established minimum clinically important difference (≥ 3 points, Group p = 0.0039). In all trajectory groups, mean fatigue levels did not change significantly between 3 and 28 days (± 1 point, Group p = 0.60).

CONCLUSION

Patient-reported fatigue varies widely among older adult outpatients with hematologic disorders. Nonetheless, trajectory modeling suggests that most anemic patients can expect a noticeable improvement in fatigue in the first few days after transfusion that generally is sustained up to 4 weeks.

Palliative and End-of-Life Care for Patients With Hematologic Malignancies

Hematologic malignancies are a heterogeneous group of diseases with unique illness trajectories, treatment paradigms, and potential for curability, which affect patients' palliative and end-of-life care needs. Patients with hematologic malignancies endure immense physical and psychological symptoms because of both their illness and often intensive treatments that result in significant toxicities and adverse effects. Compared with patients with solid tumors, those with hematologic malignancies also experience high rates of hospitalizations, intensive care unit admissions, and in-hospital deaths and low rates of referral to hospice as well as shorter hospice length of stay. In addition, patients with hematologic malignancies harbor substantial misperceptions about treatment risks and benefits and frequently overestimate their prognosis. Even survivors of hematologic malignancies struggle with late effects, post-treatment complications, and post-traumatic stress symptoms that can significantly diminish their quality of life. Despite these substantial unmet needs, specialty palliative care services are infrequently consulted for the care of patients with hematologic malignancies. Several illness-specific, cultural, and system-based barriers to palliative care integration and optimal end-of-life care exist in this population. However, recent evidence has demonstrated the feasibility, acceptability, and efficacy of integrating palliative care to improve the quality of life and care of patients with hematologic malignancies and their caregivers. More research is needed to develop and test population-specific palliative and supportive care interventions to ensure generalizability and to define a sustainable clinical delivery model. Future work also should focus on identifying moderators and mediators of the effect of integrated palliative care models on patient-reported outcomes and on developing less resource-intensive integrated care models to address the diverse needs of this population.

The IPSS-R more accurately captures fatigue severity of newly diagnosed patients with myelodysplastic syndromes compared with the IPSS index

We aimed to compare fatigue of newly diagnosed patients with myelodysplastic syndromes (MDS) with that of the general population (GP). We also investigated the ability of the IPSS and IPSS-R to capture severity of patient-reported fatigue at diagnostic workup. A sample of 927 newly diagnosed patients with MDS was consecutively enrolled in a large international observational study and all patients completed the FACIT-Fatigue questionnaire at baseline. Fatigue was compared with that of the GP (N = 1075) and a 3-point difference in mean scores was considered as clinically meaningful. Fatigue of MDS patients was on average 4.6 points below the mean of the GP (95% CI, -5.9 to -3.2, p < 0.001), reflecting clinically meaningful worse fatigue. Unlike the IPSS, the IPSS-R identified clearly distinct subgroups with regard to burden of fatigue. Mean scores differences compared with GP ranged from nonclinically relevant for very low risk (Δ = -1.8, 95% CI, -4.0 to 0.5, p = 0.119) to large clinically meaningful differences for very high-risk IPSS-R patients (Δ = -8.2, 95% CI, -10.3 to -6.2, p < 0.001). At diagnostic workup, fatigue of MDS is clinically meaningful worse than that reported by the GP. Compared with the IPSS classification, the IPSS-R provides a better stratification of patients with regard to fatigue severity.

Integrating patient-centered factors in the risk assessment of MDS

Myelodysplastic syndromes are clonal myeloid neoplasms that primarily present in older adults. Although leukemia develops in approximately 25% to 30% of individuals, the significantly shortened survival in this population is attributed more commonly to nonleukemic causes. The current prognostic scoring systems for leukemia and overall survival based on disease characteristics are becoming increasingly sophisticated and accurate with the incorporation of molecular data. The addition of patient-related factors such as comorbidity, disability, frailty, and fatigue to these new models may improve their predictive power for overall survival, treatment toxicity, and health care costs. To improve the generalizability of clinical trial results to the real world, geriatric assessment testing should become a standard of care in MDS clinical trials.

Using Social Media to Uncover Treatment Experiences and Decisions in Patients With Acute Myeloid Leukemia or Myelodysplastic Syndrome Who Are Ineligible for Intensive Chemotherapy: Patient-Centric Qualitative Data Analysis

Background

Until recently, treatment options were limited for patients with acute myeloid leukemia and myelodysplastic syndrome (AML and MDS) who are ineligible for intensive chemotherapy. Owing to the condition’s rapid progression, it is difficult to identify what is most important to patients when making treatment decisions. Patients’ needs can be better addressed by gaining a deeper understanding of their perspectives, which is valuable in the decision-making process. The Food and Drug Administration recently encouraged the use of social media as a tool to gain insight on patients’ perspectives regarding symptoms experienced and the impacts of their disease.

Objective

This study aimed to use disease-specific social media posts by patients with AML or MDS who are ineligible for intensive chemotherapy and their caregivers to capture factors they feel are most important, and to provide current evidence to inform and characterize these perspectives.

Methods

Posts by patients with AML or MDS and their caregivers were extracted from publicly available discussions on 3 large AML- or MDS–specific sites. These posts were manually reviewed to only include patients who are ineligible for intensive chemotherapy. A total of 1443 posts from 220 AML patients/caregivers and 2733 posts from 127 MDS patients/caregivers met the study inclusion criteria. A qualitative data analysis (QDA) of a sample of 85 patients’/caregivers’ posts was conducted to identify themes, and a targeted QDA of posts from 79 users focused on treatment decision discussions. Posts were manually reviewed, and relevant text segments were coded and grouped into categories and overall themes.

Results

Eighty-six percent (73/85) of users in the overall QDA had relevant information about the key objectives. The most commonly discussed treatment experience theme was the humanistic burden of AML or MDS in terms of emotional/physical impact and impact on family (86%, 63/73 of users), followed by treatment decisions (56%, 41/73) and unmet needs (50%, 37/73). In the QDA of treatment decisions, 60 posts from 45 users contained relevant information. Patients commonly reported the desire to reach specific milestones, including birthdays and weddings. They wished for a better quality of life over quantity of life, did not want the risk of suffering from side effects, and expressed a clear preference to be at home rather than in a hospital or care home.

Conclusions

This study was a novel application of disease-specific social media. It highlighted experiences in the current treatment of AML and MDS, including information gaps, patient/caregiver uncertainty, and the importance of understanding patients’/caregivers’ goals and opinions. A clear finding from this research was the importance of reaching certain personal life goals and being at home with family and friends. The analysis showed that patients/caregivers face additional challenges, including humanistic impacts and a lack of information regarding treatment options.

Patient-Reported Distress in Myelodysplastic Syndromes and Its Association With Clinical Outcomes: A Retrospective Cohort Study

Background: NCCN defines distress as a multifactorial, unpleasant emotional experience of a psychological nature that may interfere with patients' ability to cope with cancer symptoms and treatment. Patients with myelodysplastic syndromes (MDS) are at risk for distress due to the largely incurable nature of this hematopoietic malignancy and its symptom burden, yet associations with clinical outcomes are unknown. Methods: We retrospectively reviewed patient-reported distress data from adult ambulatory patients with MDS visiting a single, tertiary care medical center from July 2013 to September 2015. Demographic, diagnostic, treatment, and comorbidity information were abstracted from records along with NCCN Distress Thermometer (DT) and Problem List (PL) scores. Survival was analyzed using the Kaplan-Meier method and Cox proportional hazards regression. Results: We abstracted 376 DT scores (median, 1; range, 0-10) from 606 visits and 110 patients (median, 2 DT scores/patient; range, 1-16). NCCN Guidelines suggest that patients with DT scores ≥4 should be evaluated for referral to specialty services to address unmet needs. A total of 54 patients (49%) had at least 1 DT score ≥4 and 20 (18%) had 2 or more DT scores ≥4; 98 patients (89.1%) reported 1,379 problems during 23,613 person-days of follow-up (median, 4 problems/patient/visit; range, 1-23). The 5 most frequently reported problems were fatigue (181 times; 78 patients), pain (95 times; 46 patients), worry (80 times; 45 patients), sleep (78 times; 41 patients), and tingling hands/feet (68 times; 33 patients). After adjustment for risk stratification at diagnosis, a single point increase on the DT was associated with an increased risk of death (hazard ratio, 1.18; 95% CI, 1.01-1.36). Conclusions: Patients with MDS experience a high burden of distress, and patient-reported distress is associated with clinical outcomes. Distress should be further studied as a prognostic variable and a marker of unmet needs in MDS.

Fatigue, symptom burden, and health-related quality of life in patients with myelodysplastic syndrome, aplastic anemia, and paroxysmal nocturnal hemoglobinuria

Background

Fatigue is distressing and affects quality of life (QoL) among patients with myelodysplastic syndrome (MDS), aplastic anemia (AA), and paroxysmal nocturnal hemoglobinuria (PNH). Limited data exist on the impact of fatigue, QoL, and related symptoms in these patients.

Objective

Prospectively assess fatigue (functional assessment of cancer therapy‐anemia [FACT‐An]); QoL (FACT‐An subscales); pain (brief pain inventory); and depression, anxiety, and stress (depression anxiety stress scale‐21) and strategies used to manage these symptoms in patients with MDS, AA, and PNH.

Methods

Surveys were administered via the AA and MDS International Foundation website and database from October 2014 through April 2015 in a cross‐sectional study. Results were summarized using descriptive statistics.

Results

Of 303 patients, 145 (48%) had MDS, 84 (28%) had AA, and 74 (24%) had PNH; 31 (10%) had >1 diagnosis. The mean age was 57 years, 200 (66%) were female, and 195 (92%) were white. The mean fatigue scores were 25 (range 1‐52) for the whole cohort, 28 for AA, 25 for MDS, and 24 for PNH (P = 0.117); these are all considered severe level. The mean QoL score was 68 (range 10‐104) for the whole cohort, 67 for AA, 69 for MDS, and 67 for PNH (P = 0.821). The ranges for stress were normal; pain and depression, mild; and anxiety, moderate. The most common management strategies perceived as helpful for fatigue in the past month were preserving energy, physical activity, and naps.

Conclusions

Many patients with MDS, AA, and PNH report severe fatigue. The helpfulness of fatigue management strategies may impact patients’ continued use; whether these strategies are beneficial and decrease fatigue levels needs more study.

Proposals for revised IWG 2018 hematological response criteria in patients with MDS included in clinical trials

The heterogeneity of myelodysplastic syndromes (MDSs) has made evaluating patient response to treatment challenging. In 2006, the International Working Group (IWG) proposed a revision to previously published standardized response criteria (IWG 2000) for uniformly evaluating clinical responses in MDSs. These IWG 2006 criteria have been used prospectively in many clinical trials in MDSs, but proved challenging in several of them, especially for the evaluation of erythroid response. In this report, we provide rationale for modifications (IWG 2018) of these recommendations, mainly for "hematological improvement" criteria used for lower-risk MDSs, based on recent practical and reported experience in clinical trials. Most suggestions relate to erythroid response assessment, which are refined in an overall more stringent manner. Two major proposed changes are the differentiation between "procedures" and "criteria" for hematologic improvement-erythroid assessment and a new categorization of transfusion-burden subgroups.

Fatigue at baseline is associated with geriatric impairments and represents an adverse prognostic factor in older patients with a hematological malignancy

Prospective data on fatigue in elderly persons with a hematological malignancy are rare. We aimed to determine the prevalence of fatigue and its association with clinical outcome and geriatric impairments in older individuals newly diagnosed with blood cancer. The EORTC QLQ-C30 and a multidimensional geriatric assessment (MGA) were performed in parallel in 149 consecutive patients aged > 67 years (median 77.8 years) at Innsbruck Medical University between January 2009 and April 2016. Fatigue as defined by EORTC QLQ-C30 was the most prevalent symptom (84%) and was significantly associated with self-reported role and physical functioning, global health status and insomnia, dyspnea, and loss of appetite (p < 0.001). Remarkably, pronounced fatigue was associated with impaired performance status and objective functional capacities in MGA, with altered depression scoring, G8 screening, and elevation of serum inflammation markers (p < 0.001). Patients with minor fatigue had a median overall survival (OS) of 26.4 months, whereas those with marked fatigue displayed an OS of 7.0 months (p < 0.001). The association between fatigue and shortened OS was supported in multivariate analyses (HR 1.74, CI 1.09–2.76; p = 0.021). Fatigue is seen to have a high prevalence and to be an adverse prognostic factor in elderly patients with a hematological malignancy. The strong impact of fatigue on clinical performance and OS emphasizes the relevance of patient-reported outcomes in individualized treatment algorithms. Patients will benefit from identification of fatigue, allowing timely interventions. The correlation between fatigue, impaired performance, nutritional status, and inflammation might suggest an underlying common pathway.

Health-related quality of life in lower-risk MDS patients compared with age- and sex-matched reference populations: a European LeukemiaNet study

In myelodysplastic syndromes (MDS), health-related quality of life (HRQoL) represents a relevant patient-reported outcome, which is essential in individualized therapy planning. Prospective data on HRQoL in lower-risk MDS remain rare. We assessed HRQOL by EQ-5D questionnaire at initial diagnosis in 1690 consecutive IPSS-Low/Int-1 MDS patients from the European LeukemiaNet Registry. Impairments were compared with age- and sex-matched EuroQol Group norms. A significant proportion of MDS patients reported moderate/severe problems in the dimensions pain/discomfort (49.5%), mobility (41.0%), anxiety/depression (37.9%), and usual activities (36.1%). Limitations in mobility, self-care, usual activities, pain/discomfort, and EQ-VAS were significantly more frequent in the old, in females, and in those with high co-morbidity burden, low haemoglobin levels, or red blood cells transfusion need (p < 0.001). In comparison to age- and sex-matched peers, the proportion of problems in usual activities and anxiety/depression was significantly higher in MDS patients (p < 0.001). MDS-related restrictions in the dimension mobility were most prominent in males, and in older people (p < 0.001); in anxiety/depression in females and in younger people (p < 0.001); and in EQ-VAS in women and in persons older than 75 years (p < 0.05). Patients newly diagnosed with IPSS lower-risk MDS experience a pronounced reduction in HRQoL and a clustering of restrictions in distinct dimensions of HRQoL as compared with reference populations.

Patient-reported outcomes enhance the survival prediction of traditional disease risk classifications: An international study in patients with myelodysplastic syndromes

BACKGROUND

Current prognostic systems for myelodysplastic syndromes (MDS) are based on clinical, pathologic, and laboratory indicators. The objective of the current study was to develop a new patient-centered prognostic index for patients with advanced MDS by including self-reported fatigue severity into a well-established clinical risk classification: the International Prognostic Scoring System (IPSS).

METHODS

A total of 469 patients with advanced (ie, IPSS intermediate-2 or high-risk) MDS were analyzed. Untreated patients (280 patients) were recruited into an international prospective cohort observational study to create the index. The index then was applied to an independent cohort including pretreated patients with MDS from the Dana-Farber Cancer Institute in Boston, Massachusetts (189 patients). At baseline, patients completed the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30 (EORTC QLQ-C30).

RESULTS

A new prognostic index was developed: the FA-IPSS(h), in which FA stands for fatigue and h for higher-risk. This new risk classification enabled the authors to distinguish 3 subgroups of patients with distinct survival outcomes (ie, risk-1, risk-2, and risk-3). Patients classified as FA-IPSS(h) risk-1 had a median overall survival (OS) of 23 months (95% confidence interval [95% CI], 19-29 months), whereas those with risk-2 had a median OS of 16 months (95% CI, 12-17 months) and those with risk-3 had a median OS of 10 months (95% CI, 4-13 months). The predictive accuracy of this new index was higher than that of the IPSS alone in both the development cohort as well as in the independent cohort including pretreated patients.

CONCLUSIONS

The FA-IPSS(h) is a novel patient-centered prognostic index that includes patients' self-reported fatigue severity. The authors believe its use might enhance physicians' ability to predict survival more accurately in patients with advanced MDS. Cancer 2018;124:1251-9. © 2017 American Cancer Society.

Palliative and End-of-Life Care in Myelodysplastic Syndromes

A growing literature demonstrates that MDS is associated with significant impairments in overall quality of life. Given the poor prognosis for many patients with MDS, and the considerable morbidities associated with this disease, there is a critical need to address palliative and end-of-life care needs in this population. However, palliative and end-of-life care issues are under-represented in the MDS literature. In this article, we highlight a growing body of literature that demonstrates unmet palliative and end-of-life care needs in hematologic malignancies, including MDS, and highlight opportunities for further research and quality improvement initiatives to address unmet needs in MDS care.

Self-reported sleep disturbance and survival in myelodysplastic syndromes

Neither the prevalence of sleep disturbance nor its association with fatigue and overall survival (OS) are well understood for patients with myelodysplastic syndromes (MDS). New patients at our institution (n = 251; 2006-2014) completed the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire, which includes questions about sleep and fatigue. Fifty-three per cent reported at least 'a little' trouble sleeping. In multivariable models, anaemia and sleep disturbance were associated with fatigue (both P < 0·001). Additionally, in separate models, sleep disturbance (P = 0·002) and fatigue (P = 0·04) both predicted OS. Our data suggest that improving sleep quality may impact MDS-related fatigue and OS.

Myelodysplastic Syndromes and Acute Myeloid Leukemia in the Elderly

Myelodysplastic syndromes (MDS) and acute myeloid leukemia (AML) are hematologic diseases that frequently affect older adults. Treatment is challenging. Management of older adults with MDS and AML needs to be individualized, accounting for both the heterogeneity of disease biology and patient characteristics, which can influence life expectancy and treatment tolerance. Clinical trials accounting for the heterogeneity of tumor biology and physiologic changes of aging are needed to define optimal standards of care. This article highlights key evidence related to the management of older adults with MDS and AML and highlights future directions for research.

Myelodysplastic Syndromes in the Elderly: Treatment Options and Personalized Management

Myelodysplastic syndromes (MDS) are typical diseases of the elderly, with a median age of 68-75 years at initial diagnosis. Demographic changes producing an increased proportion of elderly in our societies mean the incidence of MDS will rise dramatically. Considering the increasing number of treatment options, ranging from best supportive care to hematopoietic stem cell transplantation (HSCT), decision making is rather complex in this cohort of patients. Moreover, aspects of the aging process also have to be considered in therapy planning. Treatment of elderly MDS patients is dependent on the patient's individual risk and prognosis. Comorbidities play an essential role as predictors of survival and therapy tolerance. Age-adjusted models and the use of geriatric assessment scores are described as a basis for individualized treatment algorithms. Specific treatment recommendations for the different groups of patients are given. Currently available therapeutic agents, including supportive care, erythropoiesis-stimulating agents (ESAs), immune-modulating agents, hypomethylating agents, and HSCT are described in detail and discussed with a special focus on elderly MDS patients. The inclusion of elderly patients in clinical trials is of utmost importance to obtain data on efficacy and safety in this particular group of patients. Endpoints relevant for the elderly should be integrated, including maintenance of quality of life and functional activities as well as evaluation of use of healthcare resources.
