Impact of different post-remission strategies on quality of life in patients with acute myeloid leukemia

Effects of different psychological interventions on quality of life and remission rate in patients with acute leukemia receiving chemotherapy: A randomized controlled trial

Aims

This study aimed to examine and compare different psychological intervention effects on the quality of life (QoL) and remission rates of patients with acute leukemia receiving chemotherapy.

Methods

A total of 180 participants were randomly divided into a cognitive intervention group, a progressive muscle relaxation (PMR) group, a cognitive intervention plus PMR group, and a usual care control group. QoL via the Chinese version of the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core-30 and remission rate were assessed at baseline and immediate post-intervention. A Generalized Linear Mixed Model was used for statistical analysis. Cost-effectiveness analysis with the value of the Incremental Cost-effectiveness Ratio was conducted to realize the economic evaluation of psychological interventions.

Results

The total score of QoL and its most dimensions were significantly improved for participants in the intervention groups compared with the control group. The cognitive intervention plus PMR intervention was the most effective concerning QoL with cost-effectiveness. No significant improvements were indicated in participants' remission rates among the groups.

Conclusion

The cognitive intervention plus PMR intervention is the most effective in improving QoL with cost-effectiveness among patients with acute leukemia receiving chemotherapy. More rigorous randomized controlled trials with multiple follow-up points are suggested to clarify the psychological interventions on remission rates in this population.

Male-specific late effects in adult hematopoietic cell transplantation recipients: a systematic review from the Late Effects and Quality of Life Working Committee of the Center for International Blood and Marrow Transplant Research and Transplant Complications Working Party of the European Society of Blood and Marrow Transplantation

Male-specific late effects after hematopoietic cell transplantation (HCT) include genital chronic graft-versus-host disease (GvHD), hypogonadism, sexual dysfunction, infertility, and subsequent malignancies. They may be closely intertwined and cause prolonged morbidity and decreased quality of life after HCT. We provide a systematic review of male-specific late effects in a collaboration between transplant physicians, endocrinologists, urologists, dermatologists, and sexual health professionals through the Late Effects and Quality of Life Working Committee of the Center for International Blood and Marrow Transplant Research, and the Transplant Complications Working Party of the European Society of Blood and Marrow Transplantation. The systematic review summarizes incidence, risk factors, screening, prevention and treatment of these complications and provides consensus evidence-based recommendations for clinical practice and future research.

Progress and Challenges in Survivorship After Acute Myeloid Leukemia in Adults

PURPOSE OF REVIEW

Acute myeloid leukemia (AML) survivors face unique challenges affecting long-term outcomes and quality of life. There is scant literature on the long-term impact of AML treatment in physical and mental health, disease recurrence, and financial burden in survivors.

RECENT FINDINGS

Fatigue, mental health concerns, infections, sexual dysfunction, and increase cancer recurrence occur after AML treatment. Chronic graft-versus-host disease (GVHD) and infections are common concerns in AML after hematopoietic stem cell transplantation (HCT). Survivorship guidelines encompass symptoms and complications but fail to provide an individualized care plan for AML survivors. Studies in patient-reported outcomes (PROs) and health-related quality of life (HRQoL) are sparse. Here we discuss the most common aspects pertaining to AML survivorship, late complications, care delivery, prevention of disease recurrence, and potential areas for implementation.

Long-term quality of life of patients with acute promyelocytic leukemia treated with arsenic trioxide vs chemotherapy

Patients with APL treated with ATRA-ATO reported better long-term quality of life outcomes than patients treated with chemotherapy.

Late comorbidity and health problem prevalence was similar between patients with APL previously treated with ATRA-ATO or chemotherapy.

The main objective of this study was to compare the long-term health-related quality of life of patients with acute promyelocytic leukemia (APL) treated with all-trans retinoic acid (ATRA) plus arsenic trioxide (ATO) vs ATRA plus standard chemotherapy. Patients previously enrolled in the randomized controlled trial APL0406 were considered eligible for this follow-up study. The following patient-reported outcome measures were used: the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Core30 (EORTC QLQ-C30), the EORTC Quality of Life Questionnaire Chemotherapy-Induced Peripheral Neuropathy 20 (QLQ-CIPN20), and the Short Form Health Survey 36 (SF-36). The prevalence of late comorbidities and health problems was also assessed. The clinical significance of differences was evaluated based on predefined thresholds. A total of 161 of 232 potentially eligible patients were analyzed, of whom 83 were treated with ATRA-ATO and 78 were treated with ATRA chemotherapy. The median time since diagnosis of the study sample was 8 years. The 2 largest clinically meaningful differences in the EORTC QLQ-C30 were observed for role functioning (Δ = 8.4; 95% confidence interval [CI], 0.5 to 16.3) and dyspnea (Δ = −8.5; 95% CI, −16.4 to −0.7), favoring patients treated with ATRA-ATO. With regard to the SF-36 results, a clinically relevant better physical component score (Δ = 4.6; 95% CI, 1.3 to 7.8) was observed in patients treated with ATRA-ATO, but this was not the case for the mental component score. The 2 groups showed similar profiles in the scores of the EORTC QLQ-CIPN20 scales and in the prevalence of late comorbidities. Overall, our findings suggest that the greater and more sustained antileukemic efficacy of ATRA-ATO is also associated with better long-term patient-reported outcomes than ATRA chemotherapy. This study was registered at www.clinicaltrials.gov as #NCT03096496.

Male-specific late effects in adult hematopoietic cell transplantation recipients: a systematic review from the Late Effects and Quality of Life Working Committee of the Center for International Blood and Marrow Transplant Research and Transplant Complications Working Party of the European Society of Blood and Marrow Transplantation

BACKGROUND

Male-specific late effects after hematopoietic cell transplantation (HCT) include genital chronic graft-versus-host disease (GvHD), hypogonadism, sexual dysfunction, infertility, and subsequent malignancies, such as prostate, penile, and testicular cancer. They may be closely intertwined and cause prolonged morbidity and decreased quality of life after HCT.

OBJECTIVE

Here, we provide a systematic review of male-specific late effects in a collaboration between transplant physicians, endocrinologists, urologists, dermatologists, and sexual health professionals through the Late Effects and Quality of Life Working Committee of the Center for International Blood and Marrow Transplant Research, and the Transplant Complications Working Party of the European Society of Blood and Marrow Transplantation.

STUDY DESIGN

We utilized systematic review methodology to summarize incidence, risk factors, screening, prevention and treatment of these complications and provide consensus evidence-based recommendations for clinical practice and future research.

RESULTS

Most of the evidence regarding male GvHD is still based on limited data, precluding strong therapeutic recommendations. We therefore recommend to systematically screen for male genital GvHD regularly and report it to large registries to allow for a better understanding. Future research should also address treatment since little published evidence is available to date. Male-specific endocrine consequences of HCT include hypogonadism which may also affect bone health. Since the evidence is scarce, current recommendations for hormone substitution and/or bone health treatment are based on similar principles as for the general population. Following HCT, sexual health decreases and this topic should be addressed at regular intervals. Future studies should focus on interventional strategies to address sexual dysfunction. Infertility remains prevalent in patients having undergone myeloablative conditioning, which warrants offering sperm preservation in all HCT candidates. Most studies on fertility rely on descriptive registry analysis and surveys, hence the importance of reporting post-HCT conception data to large registries. Although the quality of evidence is low, the development of cancer in male genital organs does not seem more prevalent than in the general population; however, subsequent malignancies in general seem to be more prevalent in males than females, and special attention should be given to skin and oral mucosa.

CONCLUSION

Male-specific late effects, probably more under-reported than female-specific complications, should be systematically considered during the regular follow-up visits of male survivors who have undergone HCT. Care of patients with male-specific late effects warrants close collaboration between transplant physicians and specialists from other involved disciplines. Future research should be directed towards better data collection on male-specific late effects and on studies about the interrelationship between these late effects, to allow the development of evidence based effective management practices.

Prognostic Impact of Pretransplantation Quality of Life and Its Post-Transplantation Longitudinal Change after Allogeneic Hematopoietic Cell Transplantation: A Prospective Study That Administered the Short-Form Health Survey (SF-12) and EuroQol 5

In allogeneic hematopoietic cell transplantation (allo-HCT), investigator-based clinical variables have been used for pretransplantation prognostic prediction, risk adjustment, and post-transplantation long-term screenings. Although several studies have investigated the prognostic significance of pretransplantation patient-reported outcomes (PROs) and longitudinal trends in PROs after allo-HCT, few have assessed these outcomes using the Medical Outcomes Study 12-Item Short-Form Health Survey (SF-12) and EuroQol 5 Dimension (EQ-5D) index. The present study used 18 items from the SF-12 and EQ-5D index to evaluate the prognostic impact of pretransplantation quality of life (QOL) on allo-HCT outcomes and longitudinal changes in QOL in allo-HCT recipients. This single-center prospective study included consecutive patients who underwent allo-HCT at our center between October 2014 and September 2016. All participants were followed up until October 2017. The SF-12 and EQ-5D index were administered to assess patient-reported QOL before allo-HCT and at 3 months, 6 months, 1 year, and 2 years after allo-HCT when participants visited the long-term follow-up clinic. Longitudinal trends in the QOL-adjusted means were estimated using linear mixed-effects, adjusting for pretransplantation covariates and reasons for missing QOL data. Among 157 patients who underwent allo-HCT, 145 (92%) were registered in this study, and 143 with available QOL data were analyzed. The median pretransplantation scores were 45.3 for the SF-12 physical component score (PCS), 55.6 for the mental component score (MCS), 38.8 for the role/social component score (RCS), 70.0 for the visual analog scale (VAS), and 49.0 for the EQ-5D index. Overall survival (OS) was significantly improved in patients with higher pretransplantation scores on the PCS, RCS, and EQ-5D index, and multivariable analyses showed that the median pretransplantation RCS was significantly associated with OS after allo-HCT (hazard ratio, 3.66; P = .003). The longitudinal trends in the SF-12 score showed that the PCS was improved at 2 years after allo-HCT and was comparable to the normative score for the general population. The MCS remained comparable to or higher than the normative score after allo-HCT. The RCS improved significantly beginning at 6 months after allo-HCT but remained lower than the normative score at 2 years. The VAS and EQ-5D index values showed a drop at 3 months after allo-HCT. Patient-reported QOL assessed by 18 questions on the SF-12 and EQ-5D predicted prognosis, and may be used as a prognosticator to determine treatment strategies, including preparative regimens. Although we experienced a certain amount of patient attrition in the longitudinal follow-up of QOL data, we demonstrated characteristic trajectories of QOL in different domains after adjusting for background covariates and reasons for the lack of QOL data. © 2021 American Society for Transplantation and Cellular Therapy.

Therapeutic Use of Valproic Acid and All-Trans Retinoic Acid in Acute Myeloid Leukemia-Literature Review and Discussion of Possible Use in Relapse after Allogeneic Stem Cell Transplantation

Even though allogeneic stem cell transplantation is the most intensive treatment for acute myeloid leukemia (AML), chemo-resistant leukemia relapse is still one of the most common causes of death for these patients, as is transplant-related mortality, i.e., graft versus host disease, infections, and organ damage. These relapse patients are not always candidates for additional intensive therapy or re-transplantation, and many of them have decreased quality of life and shortened expected survival. The efficiency of azacitidine for treatment of posttransplant AML relapse has been documented in several clinical trials. Valproic acid is an antiepileptic fatty acid that exerts antileukemic activity through histone deacetylase inhibition. The combination of valproic acid and all-trans retinoic acid (ATRA) is well tolerated even by unfit or elderly AML patients, and low-toxicity chemotherapy (e.g., azacitidine) can be added to this combination. The triple combination of azacitidine, valproic acid, and ATRA may therefore represent a low-intensity and low-toxicity alternative for these patients. In the present review, we review and discuss the general experience with valproic acid/ATRA in AML therapy and we discuss its possible use in low-intensity/toxicity treatment of post-allotransplant AML relapse. Our discussion is further illustrated by four case reports where combined treatments with sequential azacitidine/hydroxyurea, valproic acid, and ATRA were used.

Risk stratification using FLT3 and NPM1 in acute myeloid leukemia patients autografted in first complete remission

FLT3-ITD and NPM1 mutation refine prognostic stratification in acute myeloid leukemia (AML) with intermediate-risk cytogenetics. However, data on their role in patients undergoing autologous stem cell transplantation (Auto-SCT) as post-remission therapy (PRT) are limited. We therefore sought to retrospectively evaluate the role of FLT3-ITD and NPM1 in a cohort of AML patients (n = 405) with intermediate-risk cytogenetics, autografted in first complete remission (CR1). Patients were transplanted between 2000 and 2014 and reported to the European Society for Blood and Marrow Transplantation (EBMT) registry. Leukemia-free survival (LFS) was the primary outcome. Median follow-up was 5.5 years. FLT3-ITD^neg/NPM1^WT was the leading molecular subtype (50%), followed by FLT3-ITD^neg/NPM1^mut (30%). In the univariate analysis, molecular subtype was associated with LFS, overall survival (OS), and relapse incidence (RI) (p < 0.001); 5-year LFS: FLT3-ITD^neg/NPM1^mut 62%, FLT3-ITD^pos/NPM1^mut 38%, FLT3-ITD^neg/NPM1^WT 32%, and FLT3-ITD^pos/NPM1^WT 21%. At 5 years, OS and RI in the FLT3-ITD^neg/NPM1^mut subtype were 74% and 35%, respectively. The corresponding OS and RI in other subtypes were below 48% and over 57%. In a Cox multivariable model, molecular subtype was the strongest predictor of LFS, OS, and relapse. In conclusion, AML patients with intermediate-risk cytogenetics and FLT3-ITD^neg/NPM1^mut experience favorable outcomes when autografted in CR1, suggesting that Auto-SCT is a valid PRT option.

Comparison of quality of life and health behaviors in survivors of acute leukemia and the general population

We aimed to compare the health-related quality of life and health behaviors of acute leukemia (AL) survivors with that of the general population from two cohorts. AL survivors (n = 149) completed a set of questionnaires to evaluate quality of life, mental status, and health behaviors. AL survivors had more physical and mental difficulties (problems with usual activities, 15% vs. 5%, p < 0.001; anxiety or depression, 24% vs. 9%, p < 0.001; pain, 35% vs. 20%, p = 0.002) and more financial difficulties (p < 0.001) than the general population. Survivors who received stem cell transplantation (SCT) had significantly worse problems with role functioning, fatigue, pain, dyspnea, and insomnia, and had higher depression scores than chemotherapy group (p = 0.024). In terms of health behaviors, AL survivors had lower rates of smoking and drinking and higher influenza vaccination rates than the general population. However, only 17% of survivors had been recommended to receive screening for other cancers from health-care providers, and 67% thought their risk for other cancers was equal or lower than that of the general population. Cancer screening rates were even lower in the SCT group than in the chemotherapy group (p = 0.041). Our study indicates that clinicians should establish more appropriate survivorship care plans.

Autologous Stem Cell Transplantation Is a Viable Postremission Therapy for Intermediate-Risk Acute Myeloid Leukemia in First Complete Remission in the Absence of a Matched Identical Sibling: A Meta-Analysis

BACKGROUND

The preferred type of postremission therapy (PRT) for intermediate-risk acute myeloid leukemia (AML) in first complete remission (CR1) is a subject of continued debate. Although allogeneic stem cell transplantation (alloSCT) is regarded as a curative strategy for AML, the efficacy of autologous stem cell transplantation (autoSCT) for patients without a matched sibling donor (MSD) has remained controversial.

METHODS

To compare survival outcomes after alloSCT versus autoSCT for patients with intermediate-risk AML in CR1, we performed a meta-analysis of 11 clinical studies. The outcomes included relapse-free survival (RFS), overall survival (OS), relapse rate (RR), and treatment-related mortality (TRM).

RESULTS

Compared with autoSCT, alloSCT showed better RFS, OS, and RR benefits, but higher TRM. Subgroup analysis based on donor category (MSD and matched unrelated donor [MUD]) of alloSCT showed alloSCT from MSD rather than from MUD had better OS benefits compared to autoSCT. For fms-like tyrosine kinase 3 internal tandem duplications (FLT3-ITD) wild-type patients, alloSCT and autoSCT had comparable RFS and OS outcomes.

CONCLUSION

Our results suggest that, in the absence of an available MSD, autoSCT remains a viable PRT alternative for intermediate-risk AML in CR1, especially for FLT3-ITD wild-type patients.

Hematopoietic stem cell transplantation for adult patients with isolated NPM1 mutated acute myeloid leukemia in first remission

Acute myeloid leukemia (AML) in first remission (CR1) with isolated NPM1 mutation (iNPM1m) is considered a good prognosis genotype, although up to one-third relapse. To evaluate the best transplant strategy, we retrospectively compared autologous stem cell transplantation (auto-SCT), related (MSD), and fully matched unrelated (MUD) allogeneic stem cell transplantation (allo-SCT). We identified 256 adult patients including 125 auto-SCT, 72 MSD, and 59 MUD. The 2-year leukemia-free survival (LFS) was 62% in auto-SCT, 69% in MUD, and 81% in MSD (P = .02 for MSD vs others). The 2-year overall survival (OS) was not different among auto-SCT, MUD, and MSD, reaching 83% (P = .88). The 2-year non-relapse mortality (NRM) was 2.5% in auto-SCT and 7.5% in allo-SCT (P = .04). The 2-year cumulative incidence of relapse (RI) was higher after auto-SCT (30%) than after MUD (22%) and MSD (12%, P = .01). In multivariate analysis, MSD versus auto-SCT but not MUD versus auto-SCT was associated with lower RI (P < .01 and P = .13, respectively) and better LFS (P = .01 and P = .31, respectively). Age correlated with higher NRM (P < .01). Allo-SCT using MSD appears as a reasonable transplant option for young patients with iNPM1m AML in CR1. Auto-SCT was followed by worse RI and LFS, but similar OS to both allo-SCT modalities.

Health State Utilities for Acute Myeloid Leukaemia: A Time Trade-off Study

OBJECTIVES

Acute myeloid leukaemia (AML) is an aggressive haematological cancer associated with significant humanistic impact. The current study assessed how the general public in the United Kingdom (UK) values AML health states.

METHODS

The composite time trade-off (cTTO) methodology was employed to elicit health state utilities in AML. Pertinent AML literature related to symptom and quality-of-life impact including physical, functional and emotional well-being, as well as the safety profile of AML treatments, were taken into consideration for drafting health state descriptions. Ten health states included in the study were newly diagnosed AML, induction, consolidation, maintenance, long-term follow-up, relapsed/refractory, stem-cell transplant (SCT) procedure, SCT recovery, SCT long-term follow-up with complications and SCT long-term follow-up without complications. The descriptions were validated by haematologists and nurse specialists for clinical accuracy and completeness. A total of 210 individuals from the general UK population participated in the cTTO interviews. Descriptive statistics were computed for health state utility values.

RESULTS

The mean age of the participants was 44.0 years (standard deviation [SD] 14.9, range 18-81) and comprised 129 (61.4%) female participants. The utility values ranged from 0.94 (SD 0.13) for SCT long-term follow-up without complications to - 0.21 (SD 0.62) for the SCT procedure.

CONCLUSIONS

The study provides health utilities for a range of AML health states, with the SCT procedure health state being valued worse than death. The utilities obtained in this study can be employed as inputs in cost-effectiveness analyses of AML therapies.

A novel allogeneic off-the-shelf dendritic cell vaccine for post-remission treatment of elderly patients with acute myeloid leukemia

In elderly acute myeloid leukemia (AML) patients post-remission treatment options are associated with high comorbidity rates and poor survival. Dendritic cell (DC)-based immunotherapy is a promising alternative treatment strategy. A novel allogeneic DC vaccine, DCP-001, was developed from an AML-derived cell line that uniquely combines the positive features of allogeneic DC vaccines and expression of multi-leukemia-associated antigens. Here, we present data from a phase I study conducted with DCP-001 in 12 advanced-stage elderly AML patients. Patients enrolled were in complete remission (CR1/CR2) (n = 5) or had smoldering disease (n = 7). All patients were at high risk of relapse and ineligible for post-remission intensification therapies. A standard 3 + 3 dose escalation design with extension to six patients in the highest dose was performed. Patients received four biweekly intradermal DCP-001 injections at different dose levels (10, 25, and 50 million cells DCP-001) and were monitored for clinical and immunological responses. Primary objectives of the study (feasibility and safety) were achieved with 10/12 patients completing the vaccination program. Treatment was well tolerated. A clear-cut distinction between patients with and without detectable circulating leukemic blasts during the vaccination period was noted. Patients with no circulating blasts showed an unusually prolonged survival [median overall survival 36 months (range 7–63) from the start of vaccination] whereas patients with circulating blasts, died within 6 months. Long-term survival was correlated with maintained T cell levels and induction of multi-functional immune responses. It is concluded that DCP-001 in elderly AML patients is safe, feasible and generates both cellular and humoral immune responses.

Social preferences for health states associated with acute myeloid leukemia for patients undergoing treatment in the United Kingdom

Background

Health state (HS) utility values for patients with acute myeloid leukemia (AML), a hematological malignancy, are not available in the United Kingdom (UK). This study aims to develop clinically sound HSs for previously untreated patients with AML and to assign utility values based on preferences of the general UK population.

Methods

This study was conducted in the UK and comprised 2 stages. During the first stage, AML HSs were drafted based on evidence from a literature review of AML clinical and health-related quality-of-life studies (published January 2000–June 2016) and patient-reported outcome measures previously used in this population. A panel of UK hematologists with AML experience validated the clinical relevance and accuracy of the HSs. During the second stage, validated HSs were valued in an elicitation survey with a representative UK population sample using the time trade-off (TTO) method. Descriptive statistics and bivariate tests were obtained and performed.

Results

A total of eight HSs were developed and clinically validated, including treatment with chemotherapy, consolidation therapy, transplant, graft-vs-host disease (GvHD), remission, relapse, refractory, and functionally cured. In total, 125 adults participated (mean age, 49.6 years [range, 18–87 years], 52.8% female). Mean (95% confidence interval [CI]) TTO preference values (n = 120), ranked from lowest (worst HS) to highest (best HS) were as follows: refractory − 0.11 (− 0.21 to − 0.01), relapse 0.10 (0.00–0.20), transplant 0.28 (0.20–0.37), treatment with chemotherapy 0.36 (0.28–0.43), GvHD 0.43 (0.36–0.50), consolidation 0.46 (0.40–0.53), remission 0.62 (0.57–0.67), and functionally cured 0.76 (0.72–0.79). Mean (95% CI) visual analog scale preference values followed the same rank order, ranging from 0.15 (0.13–0.17) for refractory to 0.71 (0.68–0.73) for functionally cured.

Conclusions

To our knowledge, this is the first study to report utility values for AML from the UK societal perspective. Participants were able to distinguish differences in severity among AML HSs, and preference values were consistent with clinical perception of HS severity. HS preference values observed in this study may be useful in future evaluations of treatment benefit, including cost-effectiveness analyses and improved patient well-being.

Autologous hematopoietic cell transplantation for adult acute myeloid leukemia: An obsolete or resurfacing concept?

Improving long-term outcomes of adult acute myeloid leukemia (AML) patients remains a challenge. Major scientific and clinical advances have led to a better understanding of the disease biology, and the majority of patients achieve a complete remission (CR) after induction therapy. Relapse risk, however, remains considerable and is the leading cause of death in this patient population. Significant efforts to improve outcomes emphasize use of post-remission therapies such as hematopoietic cell transplantation (HCT), an increasingly utilized modality. Improvement in transplantation techniques, understanding of donor:recipient histocompatibility, and increased availability of alternative donors have resulted in greater use of allogeneic HCT. Despite a graft-versus-leukemia effect and lower post-HCT relapse rates, allogeneic HCT continues to be plagued by treatment-related mortality (TRM) and chronic graft-versus-host disease. Better understanding of AML risk stratification and issues relating to minimal residual disease (MRD) as well as extremely low TRM rates with autografts have prompted clinicians to re-explore use of autologous HCT in subsets of favorable and intermediate-risk CR1 AML patients. Herein, we highlight the evolving literature and treatment outcomes for autologous HCT in AML. We provide recommendations for considering this therapeutic modality for treatment intensification in AML.

Patient-reported outcomes in acute myeloid leukemia: Where are we now?

Outcomes for acute myeloid leukemia remain poor, and treatment decisions must consider not just quantity, but also quality of life (QOL). We conducted a systematic review of studies in patients with acute myeloid leukemia or high-risk myelodysplastic syndrome that incorporated patient-reported outcome (PRO) measures. PubMed and PsycINFO were searched for articles published from January 2000 through June 2016. Forty-one were relevant for our review with more published in recent years. There was considerable inter-study heterogeneity in which instruments were used, and many studies employed multiple (often overlapping) instruments. Longitudinal studies in particular suffered from both high attrition rates due to disease-related mortality as well as waning compliance with questionnaire completion. There remain significant challenges to incorporation of PROs into leukemia trials. Despite these limitations, however, well-implemented PROs can provide important information beyond objective response outcomes and highlight areas of focus for clinicians caring for patients and for future research endeavors.

A Single Center Survey of Health-Related Quality of Life among Acute Myeloid Leukemia Survivors in First Complete Remission

BACKGROUND

Acute myeloid leukemia (AML) is one of the most common types of leukemia in adults, but there is limited information on survivors' quality of life (QOL) after remission.

OBJECTIVE

We piloted a survey exploring patient-reported outcomes for people with AML in first complete remission (CR1) to determine whether patients felt the survey is relevant to their well-being and to summarize patient characteristics.

DESIGN/MEASUREMENTS

Cross-sectional survey of a convenience sample of AML patients in CR1 assessing QOL and functioning (European Organization for Research and Treatment of Cancer [EORTC] QLQ-C30 v 3.0), well-being (QOL-cancer survivor [QOL-CS]), fatigue (Functional Assessment of Chronic Illness Therapy-Fatigue [FACIT-Fatigue]), and anxiety and depression (hospital anxiety and depression scale [HADS]). The survey contained five open-ended questions.

RESULTS

Eighteen patients completed the survey. Most felt it was completely or mostly relevant (88.8%) in describing their QOL. Participants scored well on the EORTC QLQ-C30, fatigue being the most common symptom (83%).The FACIT-Fatigue mean score was 28.7 and median score was 33.5 (normal ≥30). Two scored in the abnormal range for anxiety and one for depression on the HADS. On the QOL-CS, participants scored more than 6 out of 10 in most domains, except the subscales of distress and fear.

CONCLUSIONS

The survey content and length were appropriate. Patients reported ongoing fatigue, fears of future test results, getting a second cancer, and recurrence of cancer. Survivors experience ongoing symptoms, highlighting the importance of providers performing ongoing symptom and needs assessments.

Health-Related Quality of Life of Patients with Acute Myeloid Leukemia: A Systematic Literature Review

INTRODUCTION

Patients with acute myeloid leukemia (AML), especially those with relapsed or refractory AML, have poor clinical prognosis and outcomes. Health-related quality of life (HRQoL) assessments have become increasingly important in oncology, aiding in identifying and informing supportive therapy needs during treatment and beyond; however, HRQoL in hematology, and AML in particular, has received relatively minor attention. The aim was to identify and summarize estimates of HRQoL in patients with AML, including patients with relapsed or refractory AML.

METHODS

A systematic literature review was performed. MEDLINE and EMBASE databases were searched for peer-reviewed literature published between 2004 and 2014 in the US and Europe. Abstracts from four relevant conference proceedings between 2012 and 2014 were reviewed. Data from eligible studies were extracted describing the HRQoL instruments used, domains assessed, and HRQoL scores reported.

RESULTS

Fourteen peer-reviewed studies met the eligibility criteria and were included in the review. Cancer- or leukemia-specific HRQoL measures were used in 78.6% of the studies. Overall, HRQoL was superior among AML survivors compared to individuals on active treatment. Fatigue was identified as the most problematic symptom domain in patients, irrespective of their treatment status. Reported HRQoL declined shortly after diagnosis or treatment initiation and recovered over time.

CONCLUSION

The included studies identified a decrease in HRQoL after treatment initiation and highlighted the role of fatigue in HRQoL in this patient population. Limited HRQoL data were identified among relapsed or refractory AML patients although they have worse prognostic outcomes. New treatment options that have less negative impact on HRQoL or health initiatives specifically targeting HRQoL of patients with AML are warranted. In addition, further studies exploring HRQoL in the relapsed or refractory patient population are needed to inform disease management and treatment decisions.

Autologous stem cell transplantation for adult acute myelocytic leukemia in first remission-Better outcomes after busulfan and melphalan compared with busulfan and cyclophosphamide: A retrospective study from the Acute Leukemia Working Party of the European Society for Blood and Marrow Transplantation (EBMT)

BACKGROUND

Autologous stem cell transplantation (ASCT) for adult acute myelogenous leukemia (AML) is a valid therapeutic option for patients with good-risk and intermediate-risk disease. The authors used the registry of the European Society for Blood and Marrow Transplantation to compare combined busulfan and melphalan (BUMEL) with combined busulfan and cyclophosphamide (BUCY) before transplantation.

METHODS

From 2005 to 2013, 853 patients with available cytogenetics underwent ASCT in first remission, including 257 after receiving BUMEL and 596 after receiving BUCY. The proportion of patients with good-risk AML was lower in those who received BUMEL (14% vs 20%; P = .02). More patients who received BUMEL underwent autograft in molecular remission (89% vs 78%; P = .02). Three years after transplantation, the relapse incidence (RI) was 48.7%, the leukemia-free survival (LFS) rate was 47.7%, the overall survival (OS) rate was 66.2%, and the nonrelapse mortality (NRM) rate was 3.6%.

RESULTS

Patients who underwent an autograft after receiving BUMEL fared better than those who underwent an autograft after receiving BUCY with a lower RI (39.5% vs 52.2%; hazard ratio [HR], 0.65; 95% confidence interval [CI], 0.49-0.87; P = .003) a better LFS (55.4% vs 44.6%; HR, 0.69; 95% CI, 0.53-0.89; P = .005), and a better OS (73.8% vs 63%; HR, 0.62; 95% CI, 0.47-0.82; P = .0007). There was no difference in the NRM rate (BUMEL vs BUCY, 4.5% vs 3.2%, respectively). Among 74 patients in the BUMEL group and 187 in the BUCY group who underwent autograft in molecular remission, the RI was 30% versus 51%, respectively (univariate analysis; P = .01), and the LFS rate was 66% versus 47%, respectively (univariate analysis; P = .03).

CONCLUSIONS

In patients with AML in first complete remission who undergo ASCT, the BUMEL combination is a better preparative regimen. Cancer 2017;123:824-31. © 2016 American Cancer Society.

Strategies for reducing the treatment-related physical burden of childhood acute myeloid leukaemia - a review

Over the last four decades the survival of paediatric patients with acute myeloid leukaemia has gradually increased to 70% in high-income countries. The therapy is very intensive and associated with many acute and long-term side effects. The early death rate has been reduced to 1-4%. The acute toxicity is a limiting factor for improving survival in low-income countries. Transplant is associated with more endocrinological late effects while cardiotoxicity is more common after relapse. Reducing the physical costs of therapy without jeopardizing survival may be accomplished by optimal supportive care, less cardiotoxic anthracyclines, less consolidation courses and strict indications for stem cell transplantation. Analysing scenarios with different frequency of transplantation in first complete remission show similar overall survival rates, indicating that almost all patients can be spared the procedure in first remission. Reducing relapse risk is an effective way of reducing toxicity and more targeted therapy and improved risk group stratifications are needed.

Continued improvement in survival of acute myeloid leukemia patients: an application of the loss in expectation of life

We evaluated temporal trends in survival of Swedish acute myeloid leukemia (AML) patients diagnosed between 1973 and 2011 using relative survival ratios (RSRs) and a measure called the loss in expectation of life (LEL). RSRs increased most for patients <60 years at diagnosis during the first calendar periods, but between 1997-2005 and 2006-2011 the most pronounced increase was for those aged 61-70 years at diagnosis; RSR changed from 0.16 (95% confidence interval (CI): 0.13-0.19) to 0.28 (95% CI: 0.23-0.33), respectively. The LEL for males aged 35 years at diagnosis was 41.0 (95% CI: 40.1-41.8) years in 1975 and 19.5 (95% CI: 16.4-22.5) years in 2011. For males aged 65 years, the corresponding figures were 13.8 (95% CI: 13.7-14.0) and 12.0 (95% CI: 11.3-12.8). Conditional LEL estimates suggested that patients who survive 5 years postdiagnosis have shorter remaining lifespan than the general population. The proportion of expected life lost (PELL) suggested that male 65-year-old patients lost 75% of their life expectancy in 2005 and 66% if they were diagnosed in 2011. Survival continued to increase to 2011, with larger improvements in those aged 61-70 years at diagnosis. The LEL and PELL are intuitive measures that may be useful in communicating survival statistics to patients, clinicians and health-care providers.

Physical function and quality of life in patients with chronic GvHD: a summary of preclinical and clinical studies and a call for exercise intervention trials in patients

Allogeneic hematopoietic stem cell transplant, to reconstitute the hematopoietic and immune status of patients undergoing myeloablative therapy for hematologic disorders, has been of great benefit in minimizing or eradicating disease and extending survival. Patients who undergo allogeneic hematopoietic stem cell transplant (allo-HSCT) are subject to many comorbidities among which the most significant, affecting quality of life (QoL) and survival, are acute GvHD (aGvHD) and chronic GvHD (cGvHD), resulting from donor lymphocytes reacting to and damaging host tissues. Physical activity and exercise have clearly been shown, in both children and adults, to enhance fitness, improve symptomatology and QoL, reduce disease progression and extend survival for many diseases including malignancies. In some cases, vigorous exercise has been shown to be equal to or more effective than pharmacologic therapy. This review addresses how cGvHD affects patients' physical function and physical domain of QoL, and the potential benefits of exercise interventions along with recommendations for relevant research and evaluation targeted at incorporating this strategy as soon as possible after allo-HSCT and ideally, as soon as possible upon diagnosis of the condition leading to allo-HSCT.

Autologous stem cell transplantation for adult acute leukemia in 2015: time to rethink? Present status and future prospects

The use of autologous stem cell transplantation (ASCT) as consolidation therapy for adult patients with acute leukemia has declined over time. However, multiple randomized studies in the past have reported lower relapse rates after autologous transplantation compared with chemotherapy and lower non-relapse mortality rates compared with allogeneic transplantation. In addition, quality of life of long-term survivors is better after autologous transplantation than after allogeneic transplantation. Further, recent developments may improve outcomes of autograft recipients. These include the use of IV busulfan and the busulfan+melphalan combination, better detection of minimal residual disease (MRD) with molecular biology techniques, the introduction of targeted therapies and post-transplant maintenance therapy. Therefore, ASCT may nowadays be reconsidered for consolidation in the following patients if and when they reach a MRD-negative status: good- and at least intermediate-1 risk acute myelocytic leukemia in first CR, acute promyelocytic leukemia in second CR, Ph-positive acute lymphocytic leukemia. Conversely, patients with MRD-positive status or high-risk leukemia should not be considered for consolidation with ASCT.

Patient-reported quality of life after allogeneic hematopoietic cell transplantation or chemotherapy for acute leukemia

When discussing treatment options for patients with acute leukemia, it is important to acknowledge the impact of allogeneic hematopoietic cell transplantation (allo-HCT) or chemotherapy on quality of life (QOL). We performed a cross-sectional questionnaire study that administered SF-36, FACT-Leukemia and EuroQOL5D to 524 acute leukemia survivors, to compare patient-reported QOL between chemotherapy and allo-HCT, and to elucidate predictors of QOL. Patients who received chemotherapy alone had a better physical QOL than those who received allo-HCT. On the other hand, the allo-HCT group reported a better mental QOL. In the comparison of QOL in the allo-HCT patients according to the presence of GVHD at survey, patients who had GVHD symptoms experienced statistically and clinically significantly worse QOL than those who did not. In the allo-HCT patients without GVHD, the physical QOL was comparable to that in the chemotherapy patients, and they experienced significantly better mental and general QOL than the chemotherapy patients. GVHD and immunosuppressive drugs at survey were strongly associated with worse QOL after allo-HCT. In the chemotherapy group, a shorter time between treatment completion and survey was significantly associated with worse QOL. Further evaluation of QOL by a longitudinal assessment with quantitative and qualitative analyses are warranted.

Factors influencing life satisfaction in acute myeloid leukemia survivors following allogeneic stem cell transplantation: a cross-sectional study

BACKGROUND

Allogeneic stem cell transplantation (alloSCT) is the preferred option of postremission therapy for high-risk patients suffering from acute myeloid leukemia (AML). Therefore, monitoring life satisfaction (LS) of long-term survivors following alloSCT is becoming increasingly important for oncologists. The aim of the study was to evaluate individual survivor priority of various general and health-related domains of life and their satisfaction with these domains. Furthermore, we investigated the impact of general and health-related LS on resilience, anxiety, depression and quality of life in AML survivors following alloSCT.

METHODS

Forty-one AML survivors (median age at time of assessment = 49.0 years) who had undergone alloSCT (median time since transplantation = 3.1 years) were enrolled in the study. Psychosocial parameters were assessed using the following instruments: FLZ(M) (Questions on Life Satisfaction), EORTC QLQ-C30, HADS (Hospital Anxiety and Depression Scale) and the RS-25 (Resilience Scale-25 items). Correlation analyses were computed to reveal the associations between the different questionnaires.

RESULTS

Independence from help or care, well-regulated living conditions and financial security contributed positively to LS, whereas being off work due to health-reasons and dissatisfaction with physical aspects were negatively associated to the subjective feelings of overall satisfaction. Moreover, a high quality of life was strongly positively correlated with LS (Spearman's rho general LS: 0.643 and health-related LS: 0.726, both p < 0.001). A high degree of resilience was also strongly positively correlated with better LS (general LS: 0.700, health-related LS: 0.675, both p < 0.001). Symptoms of anxiety and depression were associated with an impaired general LS (anxiety: -0.674, depression: -0.698, both p < 0.001).

CONCLUSIONS

Our results indicate that LS should be considered an important key contributor to the survivors' well-being following alloSCT. Thus, identifying protective psychological and physical factors that relieve stressors is of high importance in order to support long-term AML survivors with their special needs.

Optimal therapy for adult patients with acute myeloid leukemia in first complete remission

Although it is absolutely clear that postremission therapy is currently necessary to obtain disease-free long-term survivorship for patients with acute myeloid leukemia (AML) in first complete remission (CR), it is not entirely clear what form that treatment should take. High-dose cytarabine is clearly effective and there definitely is a dose-response relationship for cytarabine and remission duration. High-dose cytarabine is effective for younger patients but not elderly patients. It is effective for patients with favorable cytogenetics but it is not clear whether it is effective for patients with intermediate or unfavorable cytogenetics. Furthermore, it is not clear what the most effective and least toxic dose and schedule of high-dose cytarabine is.

Health related quality of life (HRQOL) in long-term survivors of pediatric low grade gliomas (LGGs)

The purpose of this study was to assess the health-related quality of life (HRQOL) and the impact of treatment on HRQOL in long-term survivors of pediatric low-grade gliomas (LGGs) using an adult instrument. QOL of 121 patients with a diagnosis of LGG from the Mayo Clinic were assessed using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC-QLQ-C30 for cancer in general) and (EORTC QLQ-BN20 specific for brain tumors). Median follow-up was 21.9 years for the participants. Median age at diagnosis was 11.8 years and at assessment was 33 years. Mean (standard deviation) global QOL score for the study was 78 (18) and 76.4 (22.8) in a reference population of healthy adults. Using QLQ-C30, radiation treated patients compared to non-radiation patients reported lower physical functioning (p = 0.002), role functioning (p = 0.004), and more constipation problems (p < 0.001). Patients with tumor recurrence reported lower role functioning (p = 0.016), social functioning (p = 0.040), and more financial problems (p = 0.029) compared to their counterparts. Using QLQ-BN20, patients with deep tumors compared to cortical tumors reported more bladder control problems (p = 0.016). Radiation treated patients also reported more bladder control problems (p < 0.001) compared to their counterparts. In the multivariable analysis, radiation therapy remained an independent predictor of physical and role functioning as well as symptoms related to brain tumors like visual disorders and motor dysfunction. Global QOL of long-term survivors of pediatric LGGs is similar to that of a reference population of healthy adults. The following tumor and treatment related factors were most consistently associated with poorer QOL: CNS tumor location, post-operative radiation, and tumor recurrence. Future studies are necessary to identify strategies to improve QOL in this subgroup of patients.

Sleep disruption in hematopoietic cell transplantation recipients: prevalence, severity, and clinical management

Sleep disruption is common among hematopoietic cell transplant (HCT) recipients, with over 50% of recipients experiencing sleep disruption pre-transplant, with up to 82% of patients experiencing moderate to severe sleep disruption during hospitalization for transplant and up to 43% after transplant. These rates of sleep disruption are substantially higher than what we see in the general population. Although sleep disruption can be distressing to patients and contribute to diminished quality of life, it is rarely discussed during clinical visits. The goal of the current review is to draw attention to sleep disruption and disorders (ie, insomnia, obstructive sleep apnea, restless legs syndrome) as a clinical problem in HCT in order to facilitate patient education, intervention, and research. We identified 35 observational studies published in the past decade that examined sleep disruption or disorders in HCT. Most studies utilized a single item measure of sleep, had small sample size, and included heterogeneous samples of patients. Six studies of the effects of psychosocial and exercise interventions on sleep in HCT have reported no significant improvements. These results highlight the need for rigorous observational and interventional studies of sleep disruption and disorders in HCT recipients..

Inching toward cure of acute myeloid leukemia: a summary of the progress made in the last 50 years

Despite some claims to the contrary, I believe substantial progress has been made in the last half century toward cure of acute myeloid leukemia in children and adults. The tried and true mechanism for this progress has been clinical trial and error. This method has been supplemented with an ever-increasing amount of work at the clinical laboratory interface that is beginning to allow us to develop specific therapy for afflicted individuals. This review details where we stand today and how we got here.

Impaired health-related quality of life in acute myeloid leukemia survivors: a single-center study

OBJECTIVES

The purpose of this study was to assess the impact of acute myeloid leukemia (AML) and its treatment on health-related quality of life (HRQOL) by comparing the HRQOL of AML survivors with the HRQOL in the general population.

METHODS

Two HRQOL questionnaires (EQ-5D and QLQ-C30) were sent to patients diagnosed with AML between 1999 and 2011 at a single academic hospital and still alive in 2012. HRQOL in AML survivors was compared with general population reference values. Multivariate analysis was used to identify factors associated with HRQOL in AML survivors.

RESULTS

Questionnaires were returned by 92 of the 103 patients (89%). AML survivors reported significantly worse functioning, more fatigue, pain, dyspnea, appetite loss, and financial difficulties and lower EQ-VAS scores than the general population (P < 0.05). Impaired HRQOL in AML survivors was mainly found in survivors without a paid job. Other factors associated with a poor HRQOL were allogeneic hematopoietic stem cell transplantation and the absence of social support.

CONCLUSION

This single-center study showed that the HRQOL in AML survivors is worse than the HRQOL in the general population. HRQOL in these patients can be improved by adequately treating and preventing fatigue, pain, dyspnea, and appetite loss.

Adult Acute Myeloid Leukemia Long-term Survivors

The number of leukemia patients and survivors is growing. This review summarizes what is known regarding the health related quality of life (HRQOL) and medical complications associated with acute myeloid leukemia (AML) disease and treatment and highlights understudied aspects of adult AML survivorship care, and potential novel areas for intervention.

The value of allogeneic and autologous hematopoietic stem cell transplantation in prognostically favorable acute myeloid leukemia with double mutant CEBPA

The clinical value of allogeneic hematopoietic stem cell transplantation (alloHSCT) and autologous hematopoietic stem cell transplantation (autoHSCT) in the subtype of acute myeloid leukemia (AML) with double mutant CEBPA (CEBPAdm) has remained unsettled. Among 2983 patients analyzed for CEBPA mutational status (age 18-60 years) treated on 4 published Dutch-Belgian-Swiss Hemato-Oncology Cooperative Group (HOVON/SAKK) and 3 German-Austrian AML Study Group (AMLSG) protocols (2 published, 1 registered, clinicaltrials.gov NCT00151255), 124 had AML with CEBPAdm and achieved first complete remission (CR1). Evaluation of the clinical impact of alloHSCT and autoHSCT vs chemotherapy was performed by addressing time dependency in the statistical analyses. Thirty-two patients proceeded to alloHSCT from a matched related (MRD, n = 29) or a matched unrelated donor (MUD, n = 3), 20 to autoHSCT in CR1 and 72 received chemotherapy. Relapse-free survival was significantly superior in patients receiving an alloHSCT or autoHSCT in CR1 as compared with chemotherapy (P < .001), whereas overall survival was not different (P < .12). Forty-five patients relapsed. Of 42 patients treated with reinduction therapy, 35 achieved a second CR (83%) and most patients (n = 33) received an alloHSCT MRD, n = 11; MUD, n = 19; haplo-identical donor, n = 3). Survival of relapsed patients measured from date of relapse was 46% after 3 years. Adult AML patients with CEBPAdm benefit from alloHSCT and autoHSCT; relapsed patients still have a favorable outcome after reinduction followed by alloHSCT.

The European LeukemiaNet AML Working Party consensus statement on allogeneic HSCT for patients with AML in remission: an integrated-risk adapted approach

Allogeneic haematopoietic stem-cell transplantation (HSCT) is frequently applied as part of the treatment in patients with acute myeloid leukaemia (AML) in their first or subsequent remission. Allogeneic HSCT reduces relapse, but nonrelapse mortality and morbidity might counterbalance this beneficial effect. Here, we review recent studies reporting new disease-specific prognostic markers, in addition to allogeneic-HSCT-related risk factors, which can be assessed at specific time points during treatment. We propose risk assessment as a dynamic process during treatment, incorporating both disease-related and transplant-related factors for the decision to proceed either to allogeneic HSCT or to apply a nontransplant strategy. We suggest that allogeneic HSCT might be favoured if the projected disease-free survival is expected to improve by at least 10% based on an individual's risk assessment. The approach requires initial disease risk assessment, identifying a sibling or unrelated donor soon after diagnosis and the incorporation of time-dependent risk factors, all within the context of an integrated therapeutic management approach.

Evaluation of health related quality of life in 6-18 years old patients with acute leukemia during chemotherapy

OBJECTIVE

To evaluate the quality of life (QOL) of Iranian children with acute leukemia during chemotherapy.

METHODS

One hundred patients between 6 to 18-years-old were selected by convenient sampling method. EORTC QLQ-C30 Questionnaire was completed by their parents' help. Demographic information such as age, sex and type of leukemia were also collected. These data were evaluated by SPSS software, Chi-square and independent sample T test. The relation between different scales of questionnaire and variables was measured and final results were compared with reference values.

RESULTS

In acute Lymphoblastic Leukemia patients QOL, physical and cognitive functions were lower in comparison with acute myelogenous leukemia and they had more fatigue, pain and insomnia. The patients between ages of 12-18-years-old had more financial difficulties and diarrhea and lower cognitive function in comparison with 6-12-years-old patients. The present patients achieved higher scores than reference value, but they had more economic problem.

CONCLUSIONS

The patients had relatively good QOL. The lowest impression was in cognitive function and the highest was in emotional function. The patients mostly complained of financial difficulties and fatigue and rarely of diarrhea and constipation. It is necessary to do more researches related to health related QOL in pediatric patients.

Quality of life issues in elderly acute myeloid leukemia patients

The median age of acute myeloid leukemia (AML) is 70 years. Treatment approaches include standard chemotherapy, palliative chemotherapy and investigational agents, depending upon disease biology and patient factors. In this article, we highlight the issues involved in the treatment of AML in older patients, focusing on the quality of life changes associated with each treatment modality at different stages of their disease course. We further discuss recent insights into the biological basis of quality of life changes, and examine potential ways to improve these through pharmacological and nonpharmacological means. Finally, we explore avenues for future research into the quality of life of the older AML patient.

Quality of life in patients before and after haematopoietic stem cell transplantation measured with the European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Core Questionnaire QLQ-C30

The EORTC Quality of Life Core Questionnaire QLQ-C30 is widely used, but no reference values are available for patients receiving HSCT. We retrieved data for 38 samples from 33 papers in English and German that provided evaluable information on QLQ-C30 scores (mean, s.d.) covering about 2800 patients. Results are presented as a table that provides reference data that allow QLQ-C30 scores at different points during the disease trajectory to be put in context. With respect to their central tendency and their variance, scores vary over time. Quality of life is lowest during inpatient time. About 1 year after HSCT, the pre-transplant level is reached. Physical functioning is the scale reaching the highest level of all scales. Fatigue, dyspnoea and insomnia are symptoms that remain at an elevated level and should thus be considered as persisting problems after HSCT. For the interpretation of differences between scores, a very conservative recommendation would be to set the s.d. at 30 points. Doing so, one could be quite sure of having found a clinically significant change if the difference of two scores exceeds 15 points. Differences below 5 points should be interpreted with caution.

Function, adjustment, quality of life and symptoms (FAQS) in allogeneic hematopoietic stem cell transplantation (HSCT) survivors: a study protocol

Background

The population of survivors following allogeneic HSCT continues to increase, and yet their experiences of recovery and long-term survivorship have not been fully characterized. This paper presents a study protocol examining over time the functional status, psychosocial adjustment, health-related quality of life, and symptom experience of survivors who have undergone allogeneic transplantation. The aims of the study are to: 1) explore the patterns of change in these health outcomes during the survivorship phase; 2) characterize subgroups of survivors experiencing adverse outcomes; and 3) examine relationships among outcomes and demographic and clinical factors (such as age, graft-versus-host disease (GVHD), and disease relapse).

Methods

In this longitudinal observational study, adults who survive a minimum of 3 years from date of allogeneic transplantation complete a series of questionnaires annually. Demographic and clinical data are collected along with a series of patient-reported outcome measures, specifically: 1) Medical Outcomes Study SF- 36; 2) Functional Assessment of Chronic Illness Therapy (FACIT) - General, 3) FACIT-Fatigue; 4) FACIT- Spiritual; 5) Psychosocial Adjustment to Illness Scale; 6) Rotterdam Symptom Checklist-Revised; and 7) Pittsburgh Sleep Quality Index.

Conclusions

This study will provide multidimensional patient-reported outcomes data to expand the understanding of the survivorship experience across the trajectory of allogeneic transplantation recovery. There are a number of inherent challenges in recruiting and retaining a diverse and representative sample of long-term transplant survivors. Study results will contribute to an understanding of outcomes experienced by transplant survivors, including those with chronic GVHD, malignant disease relapse, and other late effects following allogeneic transplantation.

Low risk of chronic graft-versus-host disease and relapse associated with T cell-depleted peripheral blood stem cell transplantation for acute myelogenous leukemia in first remission: results of the blood and marrow transplant clinical trials network protocol 0303

Graft-versus-host disease (GVHD) is most effectively prevented by ex vivo T cell depletion (TCD) of the allograft, but its role in the treatment of patients undergoing allogeneic hematopoietic cell transplantation (HCT) for acute myelogenous leukemia (AML) in complete remission (CR) remains unclear. We performed a phase 2 single-arm multicenter study to evaluate the role of TCD in AML patients in CR1 or CR2 up to age 65 years. The primary objective was to achieve a disease-free survival (DFS) rate of >75% at 6 months posttransplantation. A total of 44 patients with AML in CR1 (n = 37) or CR2 (n = 7) with a median age of 48.5 years (range, 21-59 years) received myeloablative chemotherapy and fractionated total body irradiation (1375 cGy) followed by immunomagnetically selected CD34-enriched, T cell‒depleted allografts from HLA-identical siblings. No pharmacologic GVHD prophylaxis was given. All patients engrafted. The incidence of acute GVHD grade II-IV was 22.7%, and the incidence of extensive chronic GVHD was 6.8% at 24 months. The relapse rate for patients in CR1 was 17.4% at 36 months. With a median follow-up of 34 months, DFS for all patients was 82% at 6 months, and DFS for patients in CR1 was 72.8% at 12 months and 58% at 36 months. HCT after myeloablative chemoradiotherapy can be performed in a multicenter setting using a uniform method of TCD, resulting in a low risk of extensive chronic GVHD and relapse for patients with AML in CR1.

Quality of life in patients with diffuse large B-cell lymphoma treated with dose-dense chemotherapy is only affected temporarily

(R)-CHOP-14 has substantially improved outcome in DLBCL, but may have increased morbidity and reduced quality of life (QoL). Our aim was to evaluate QoL during (R)-CHOP-14-based chemotherapy. Twenty-six patients participated (small single-center study). EORTC QLQ-C30 was completed pre-treatment, mid-treatment, 14 days post-treatment, and 3 months post-treatment. Scores were compared to a reference population, and analyzed separately. Pre-treatment, global health status (p = 0.004), physical functioning (p = 0.036), role functioning (p = 0.017), and emotional functioning (p = 0.040) were reduced, and fatigue (p = 0.009) and appetite loss (p = 0.007) increased compared to the reference population. During treatment, physical functioning and role functioning decreased significantly, whereas emotional functioning, fatigue, and diarrhea increased. Three months post-treatment, scores were generally equivalent to those of the reference population, and lower for nausea/vomiting (p < 0.001) and constipation (p < 0.001). Disease-related symptoms were frequent in high-risk DLBCL. Treatment-related symptoms were normalized 3 months post-treatment. In conclusion, QoL is only temporarily affected during (R)-CHOP-14-based chemotherapy, and the treatment regimen is therefore feasible.

Measuring social activities and social function in long-term cancer survivors who received hematopoietic stem cell transplantation

OBJECTIVE

Cancer survivors report deficits in social functioning even years after completing treatment. Commonly used measures of social functioning provide incomplete understanding of survivors' social behavior. This study describes social activities of survivors and evaluates the psychometric properties of the Social Activity Log (SAL) in a cohort of long-term survivors of hematopoietic stem cell transplantation (HSCT) for cancer.

METHODS

One hundred and two (5-20 year) survivors completed the SAL, Short-Form-36 Health Survey (SF-36), and other patient-reported outcomes. Principal components analysis determined the factor structure of the SAL along with correlations and regressions to establish validity.

RESULTS

Principal component analysis yielded three factors in the SAL: 'non-contact events' (e.g. telephone calls), 'regular events' (e.g. played cards), and 'special events' (e.g. concerts), which explained 59% of the total variance. The SAL possessed good internal consistency (Cronbach's alpha=0.82). SF-36 social function and SAL were moderately correlated (r=0.31). In linear regressions, physical function and depression explained 16% of the variance in the SAL (P<0.001), while physical function, depression, and fatigue predicted 55% of the variance in SF-36 social function (P<0.001).

CONCLUSIONS

Results support the use of the SAL as a measure of social activity in cancer survivors who received HSCT. Although the SAL is designed to measure social behaviors, SF-36 social function assesses subjective experience and is more strongly associated with depression and fatigue. The SAL appears to be a promising tool to understand the behavioral social deficits reported by long-term survivors of cancer.

Favorable outcomes in patients surviving 5 or more years after allogeneic hematopoietic stem cell transplantation for hematologic malignancies

Allogeneic hematopoietic stem cell transplantation (HSCT) is a curative treatment for some hematologic malignancies. As the overall number of survivors continues to increase, studies systematically examining outcomes in long-term survivors are needed. We studied the clinical and quality-of-life outcomes in HSCT recipients surviving 5 or more years from HSCT. Since 1993, 262 patients with hematologic malignancies received a T cell-depleted myeloablative HSCT from an HLA-identical sibling at a single center. Ninety-two survived beyond 5 years from HSCT (median follow-up 9.4 years, range: 5.1-15.3). Median age at transplantation was 35 years (range: 10-56). Twenty-two (24%) received a bone marrow transplant, and 70 (76%) received a peripheral blood HSCT. Of the 92 survivors, 60 completed quality-of-life measures. The main outcomes examined were chronic graft-versus-host-disease, disease relapse, survival, health-related quality-of-life (HRQL) (Functional Assessment of Cancer Therapy-General), physical and mental health (SF-36), and symptom experience (Rotterdam Symptom Checklist). Seventy-five (82%) of 92 survivors no longer required systemic immunosuppressive treatment. Four (4.3%) relapsed with leukemia at a median of 8.5 years (range: 6.2-14.0) after HSCT. Four (4.3%) died between 7.4 and 13.4 years post-HSCT (1 relapse, 1 lung cancer, 1 pneumonia, 1 brain hemorrhage). Most survivors beyond 5 years had an excellent performance status with no difference in physical and mental health and higher HRQL scores (P = .02) compared with population norms. Although physical and psychologic symptom distress was low, those with higher symptom distress experienced inferior HRQL. These results show that 5 or more years after T cell-depleted HSCT for hematologic malignancy most individuals survive disease free with an excellent performance status, preserved physical and psychological health, and excellent HRQL.

Stem cell source and outcome after hematopoietic stem cell transplantation (HSCT) in children and adolescents with acute leukemia

Allogeneic hematopoietic stem cell transplantation from siblings, unrelated donors or HLA mismatched family members has become an important procedure to offer a chance of cure to children and adolescents with acute leukemia at high risk of relapse and those with certain genetic diseases. Bone marrow (BM) was the only stem cell source for many years. During the past 15 years, peripheral blood stem cells from granulocyte colony-stimulating factor (G-CSF) mobilized healthy donors, or umbilical cord blood from related or unrelated donors, have become available. Each stem cell source has different risks/benefits for patients and donors, the choice depending not only on availability, but also on HLA compatibility and urgency of the HSCT. This review will analyze the advantages and limitations of each of these options, and the main criteria which can be applied when choosing the appropriate stem cell source for pediatric transplant recipients with acute leukemia.
