Quality of life of patients with chronic lymphocytic leukemia: results of a longitudinal investigation over 1 yr

Relationship between quality of life before treatment and survival in patients with hematological malignancies: A meta-analysis

This meta-analysis aimed to investigate the impact of pretreatment quality of life (QoL) on overall survival (OS) in patients with hematological malignancies. The observational studies with relationship between QoL and OS in patients undergoing either hematopoietic stem cell transplantation (HSCT) or chemotherapy were collected. Stratification by treatment was performed to examine the association between QoL and OS. Six articles were included in the analysis. Overall, significant associations with OS were observed for global QoL (hazard ratio [HR] = 1.04, 95% confidence interval [CI] = 1.01-1.08), physical QoL (HR = 1.06, 95% CI:1.02-1.10), and social QoL (HR = 1.02, 95% CI: 1.00-1.03). When stratified by treatment, HSCT showed significant associations between OS and both global QoL (HR = 1.05, 95% CI:1.00-1.11) and physical QoL (HR = 1.03, 95% CI:1.00-1.06). For chemotherapy, significant associations were also observed between OS and global QoL (HR = 1.04, 95% CI:1.00-1.09), physical QoL (HR = 1.08, 95% CI:1.00-1.17), role QoL (HR = 1.02, 95% CI:1.00-1.04), and social QoL (HR = 1.02, 95% CI:1.00-1.04). No significant associations were observed regarding emotional QoL, which was only analyzed in HSCT. The factors influencing OS may vary depending on the treatment, emphasizing the importance of recognizing QoL from the pretreatment stage.

Impact of lenalidomide consolidation on health-related quality of life in chronic lymphocytic leukemia: ancillary study of the phase III CLL6-RESIDUUM trial

BACKGROUND

Within the French-Australian CLL6 RESIDUUM trial, an ancillary study aimed at assessing the health-related quality of life (HRQoL) of patients with chronic lymphocytic leukemia (CLL) receiving a two-year consolidation of lenalidomide (LEN) or observation (OBS) after classical immunochemotherapy leaving them with detectable residual disease.

METHODS

Data from French patients involved in this the trial were used here. The EORTC QLQ-C30 version 3 questionnaire was completed by patients at baseline, and then at months 3, 6, 12, 18 and 24 after consolidation. Repeated measures mixed-effects models were used to assess HRQoL changes between baseline and each checkpoint for each HRQoL scale.

RESULTS

Baseline data showed overall a good global health status with mean scores of 76.3 and 72.1 in the LEN and OBS arms respectively, on the 0-100 scale. At 12 months, LEN patients had significantly more diarrhea than OBS patients (p = 0.003) and social functioning was significantly impaired at month 18 (p = 0.05). A 10-point difference appeared in the LEN arm for dyspnea and digestive disorders from month 12 on. Multivariate analysis showed a deleterious effect of LEN on global health (p = 0.02) and functional scales (p = 0.003).

CONCLUSION

This study provides HRQoL values in a French cohort of CLL patients in consolidation treatment. Supplementation with lenalidomide as consolidation therapy in CLL leads to late health deterioration, especially diarrhea, after 12 months of treatment. Quantitative assessment of HRQoL should be balanced against benefits in disease control to determine overall health benefits.

Indolent lymphoma: addressing the needs of survivors

Over the past two decades, there has been a continuous improvement in outcome for patients with indolent lymphoma (iNHL) resulting in a gradual accumulation of survivors. While life expectancy in the current era approaches that of the lymphoma-free population, patients continue to experience lifelong complications of the disease and its treatment affecting general health, emotional, psychological and social wellbeing, relationships, employment, finances, and fitness. Contemporary care models while suited to the management of lymphoma are often lacking when it comes to identification and management of these additional needs. Given improvements in physical survival achieved over the past decades, it is timely for us to focus on other issues affecting patient wellbeing including immunodeficiency and infection, second cancers, cardiovascular disease, bone health, psychological wellbeing, and sexual health. Many of these aspects are in the domain of the primary care physician; however, there is limited guidance on how these issues should be addressed. It is now time for us to engage our patients, their caregivers, and other healthcare providers in care aspects beyond the lymphoma diagnosis, so they can anticipate a rich and full life, free from both direct and indirect consequences of the lymphoma diagnosis.

Chronic Lymphocytic Leukemia Care and Beyond: Navigating the Needs of Long-Term Survivors

Chronic lymphocytic leukemia (CLL) treatment has undergone a significant evolution with a shift from historical chemotherapeutic regimens to targeted therapies such as Bruton tyrosine kinase (BTK) and BCL-2 inhibitors. These advancements have been associated with a notable improvement in survival rates with a transformation of CLL into a chronic and manageable condition for most persons with this disease. However, as a consequence of improved outcomes, long-term CLL survivors now face emergent challenges which include a risk of infections, cardiovascular complications, and secondary malignancies. In this changed scenario, holistic models of care are essential to address emergent health risks. Such models of care for CLL patients require a multidisciplinary approach that integrates CLL treatment with the proactive management of frailty, comorbidities, and psychosocial well-being to enhance both survival and quality of life (QoL). CLL predominantly affects older persons, many of whom present with concurrent frailty and comorbidities that may complicate CLL treatment and impact QoL. Comprehensive geriatric assessments (GA) may play a critical role in the identification of persons at a heightened risk of treatment-related toxicity and may help guide rational therapy selection, particularly in very frail persons. In addition to the assessment of hematological responses, the prospective assessment of patient-reported outcomes (PROs) and frailty metrics may offer a more nuanced understanding of the global treatment benefits. A survivorship-focused care model is crucial to address the multifaceted needs of CLL patients with the extension of patient care into the broader domain of long-term health maintenance with associated improvements in QoL.

Establishing meaningful change thresholds for European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire CLL-specific module domain scores: An analysis based on the TRANSCEND CLL 004 study in patients with relapsed or refractory chronic lymphocytic leukaemia or small lymphocytic lymphoma

Introduction

The study aimed to establish meaningful thresholds at patient and group levels for the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire CLL-specific module (EORTC QLQ-CLL17) domain scores in adults with relapsed or refractory (R/R) chronic lymphocytic leukaemia (CLL).

Material and methods

Data for the analysis were from the TRANSCEND CLL 004 study (NCT03331198). EORTC QLQ-CLL17 and selected anchor measures were assessed at baseline and multiple postbaseline visits up to 24 months after treatment initiation. Thresholds for each of the three EORTC QLQ-CLL17 domains were triangulated based on estimates derived from anchor- and distribution-based analyses, in accordance with published guidance.

Results

The analysis included 62 patients with 240 observations across visits. Meaningful change thresholds for improvement and deterioration, respectively, at the patient level were determined to be -11/+11 for symptom burden, -16/+16 for physical condition/fatigue and -16/+13 for worries/fears on health and functioning. The meaningful change thresholds for improvement and deterioration at the group level mostly ranged between 0.3 and 0.5 of the standard deviation of baseline domain scores.

Conclusions

These thresholds, based on EORTC QLQ-CLL17 domain scores, could help identify patients with meaningful changes in HRQOL and interpret treatment effects in future studies of treatments for adults with R/R CLL.

Psycho-oncological burden in patients with brain metastases undergoing neurological surgery

Purpose

The development of brain metastases (BM) can significantly increase the psycho-oncological burden in cancer patients, requiring timely intervention. In addition, this aspect may negatively affect the course of the disease and treatment outcome. However, screening for psycho-oncological burden is often overlooked in clinical routine. Therefore, we analyzed the extent of psycho-oncological distress in a patient population with BM receiving neurosurgical resection and identified clinical characteristics associated with a high need for psycho-oncological intervention.

Methods

We prospectively screened 353 patients (169 female, 184 male, mean age 61.9 years) scheduled for microsurgical resection of one or more BM. Psycho-oncological screening was performed on the day of admission using the Hornheider screening instrument (HSI) and the distress thermometer (DT). Screening results were correlated with demographic and clinical data.

Results

Most patients (73.1%) completed the screening questionnaire. Patients who failed to complete the questionnaire presented more frequently with metachronous BM (74.7% vs. 25.3%, p=0.009), were significantly older (p=0.0018), and had a significantly lower KPS score (p=0.0002). Based on the threshold values of the questionnaires, 59.3% of the patients showed a significant psycho-oncological burden requiring immediate intervention. Univariate analysis demonstrated that synchronous BM (p=0.034), tumors in eloquent areas (p=0.001), lower KPS (p=0.031), female gender (p=0.009), and presurgical aphasia (p=0.042) were significantly associated with high psycho-oncological burden. Multivariate analysis showed synchronous BM (p=0.045), female gender (p=0.005), and lower KPS (p=0.028) as independent factors associated with high psycho-oncological burden.

Conclusion

The majority of patients with BM have a high psycho-oncological burden. Female gender, synchronous BM, and lower KPS are independently associated with a need for psycho-oncological intervention.

Health-related quality of life in older hematological cancer survivors (70+) compared to older general population-A German cancer-register-based cross-sectional comparative study

OBJECTIVES

The extent of health-related quality of life (HRQOL) impairments in older hematological cancer survivors (HCS) has not been sufficiently studied. We therefore examined HRQOL in older HCS compared to a community sample (CS) and investigated sociodemographic, disease- and treatment-specific, geriatric, and psychosocial factors associated with reduced HRQOL.

MATERIALS AND METHODS

In this cancer-register-based cross-sectional comparative study 200 HCS, aged ≥70 years, and 252 persons of an age- and gender-matched CS completed validated questionnaires including the EORTC QLQ-C30 and EORTC QLQ-ELD14.

RESULTS

Older HCS reported a reduced HRQOL in the dimensions of global QOL, physical, role, and social functioning (small clinical significance) and higher symptom burden of fatigue, nausea and vomiting, appetite loss, and poorer mobility compared to the CS (fatigue and mobility with medium, the others with small clinical significance). Perceived disease burden of comorbidities, functional disabilities, psychological distress, and depression showed statistical significance for reduced HRQOL in older HCS in multiple linear regression analysis (R2 = .602, p < .001).

DISCUSSION

The screening and treatment of functional limitations and individual symptoms and the integration of a geriatric assessment into oncological practice can help to identify supportive care needs, to implement individualized, patient-centered cancer survivorship care programs and to improve older HCS's HRQOL.

Quality of Life of Hematological Neoplasm Survivors After Hematopoietic Stem Cell Transplantation

PURPOSE

This study aimed to assess changes in the quality of life (QoL) of patients with hematological neoplasms who underwent hematopoietic stem cell transplantation (HSCT), identify factors influencing these changes, and quantify the associated monetary value.

METHODS

A total of 122 hematopoietic stem cell transplantation (HSCT) recipients participated in the study completing a recall survey with questions about 3 different stages: (1) pre-HSCT (baseline), (2) 6 months post-transplantation, and (3) between the first and fifth post-transplantation years. The study first estimated the incremental variation in QoL between phases and conducted regression analyses to identify factors linked to QoL changes. Second, it explored the transition probabilities of QoL between phases and their monetary value.

RESULTS

Baseline QoL predominantly determined future QoL changes, with disease type, transplantation type, and other sociodemographic factors proving insignificant. Notably, patients with the lowest baseline QoL experienced greater QoL improvement post-HSCT compared to others. Specifically, 90% of patients elevated their QoL quartile within the first post-transplantation year, with over 20% reaching the highest quartile and an average QoL increase of 0.619. The incremental economic benefit for patients with poor baseline QoL, compared to those with high baseline QoL, was 56,880€.

CONCLUSION

This study provides new, useful, and relevant information on the evolution of the QoL of these patients. Our findings support that HSCT significantly enhances QoL for survivors with initially low QoL, while those with high pre-HSCT QoL maintain their levels. Furthermore, other factors were not significant contributors to this relationship. The study introduced a novel method to measure the economic benefit of incremental QoL.

Health-related quality of life in adults with hematological cancer: a 2023 cross-sectional survey from Qatar

Background

Hematological cancers impose a complex burden on individuals, affecting their physical health and mental and emotional well-being. This study evaluated the health-related Quality of Life (HRQOL) and its determinants among adults with hematological cancers in Qatar in 2023.

Methods

A cross-sectional study used a validated structured questionnaire conducted among adult patients diagnosed with hematological cancers. All adult patients who attended The National Centre for Cancer Care and Research (NCCCR) in Qatar during the Data collection period (January to March 2023) and agreed to participate were included in the study.

Results

A total of 257 participants were enrolled in the study. The highest median (IQR) score of the HRQOL domain was observed in the functionating score of 90.6 (13.8), followed by the global health score of 83.3(25. 0). The median (IQR) of the symptoms burden score was 07.4(12.3). Gender significantly affects HRQOL, with males reporting better functioning and lower symptom burden than females. Employment status is positively associated with functioning scores. Regular exercise correlates with higher global health and functioning scores and lower symptom burden, while depressive symptoms are linked to poorer HRQOL outcomes. Patients experiencing cancer recurrence or active disease report lower global health and functioning scores and higher symptom burden. Treatment modalities such as chemotherapy and bone marrow transplant (BMT) timing also influence HRQOL, with recent treatment recipients showing lower global health and higher symptom burden scores. Depressive symptoms were the primary factor, lowering the global health score by 15.2%. Regarding the low functioning score predictors, female gender, depressive symptoms, and cancer recurrence emerged as significant predictors of the low functioning score. Furthermore, Regular exercise increased the functioning score by 03.4 units (p-value=0.018). Finally, Multiple linear regression analysis reinforced the significance of depressive symptoms, active disease status, and recurrence within the past five years as substantial predictors of higher symptom scores.

Conclusions

The study emphasizes the profound impact of depressive symptoms on all aspects of Health-Related Quality of Life (HRQOL), mainly affecting global health. It highlights the positive role of regular exercise in enhancing global health, functioning, and symptom burden scores.

Management and use of healthcare resources in patients with chronic lymphocytic leukemia initiating venetoclax in routine clinical practice

Venetoclax is a first-in-class B-cell lymphoma-2 (BCL-2) inhibitor approved as continuous monotherapy and in combination with rituximab as fixed-treatment duration for relapsed and refractory chronic lymphocytic leukemia (R/R CLL). DEVOTE was a 24-week, multicenter observational study (NCT03310190) evaluating the safety, healthcare resource utilization (HCRU) and health-related quality of life (HRQoL) of patients initiating venetoclax for R/R CLL in Canada. Overall, 89 patients received 1 dose of venetoclax; 80% had prior exposure (42% resistant) to ibrutinib. Biochemical tumor lysis syndrome (TLS) occurred in five patients. We observed differences in hospitalization across Canadian provinces including in patients at low risk for TLS with no clear impact on TLS incidence. Additionally, a rapid and sustained improvement in several domains of HRQoL was observed during venetoclax initiation. Early adoption of venetoclax was mainly for R/R CLL patients with few treatment options; nonetheless, acceptable toxicity and a positive impact on HRQoL were observed.

Chemobrain in blood cancers: How chemotherapeutics interfere with the brain's structure and functionality, immune system, and metabolic functions

Cancer treatment brings about a phenomenon not fully clarified yet, termed chemobrain. Its strong negative impact on patients' well-being makes it a trending topic in current research, interconnecting many disciplines from clinical oncology to neuroscience. Clinical and animal studies have often reported elevated concentrations of proinflammatory cytokines in various types of blood cancers. This inflammatory burst could be the background for chemotherapy-induced cognitive deficit in patients with blood cancers. Cancer environment is a dynamic interacting system. The review puts into close relationship the inflammatory dysbalance and oxidative/nitrosative stress with disruption of the blood-brain barrier (BBB). The BBB breakdown leads to neuroinflammation, followed by neurotoxicity and neurodegeneration. High levels of intracellular reactive oxygen species (ROS) induce the progression of cancer resulting in increased mutagenesis, conversion of protooncogenes to oncogenes, and inactivation of tumor suppression genes to trigger cancer cell growth. These cell alterations may change brain functionality, as well as morphology. Multidrug chemotherapy is not without consequences to healthy tissue and could even be toxic. Specific treatment impacts brain function and morphology, functions of the immune system, and metabolism in a unique mixture. In general, a chemo-drug's effects on cognition in cancer are not direct and/or in-direct, usually a combination of effects is more probable. Last but not least, chemotherapy strongly impacts the immune system and could contribute to BBB disruption. This review points out inflammation as a possible mechanism of brain damage during blood cancers and discusses chemotherapy-induced cognitive impairment.

Gender disparities in health-related quality of life (HRQoL) in patients with cutaneous T-cell lymphoma

Patients with cutaneous T-cell lymphoma (CTCL) often experience debilitating symptoms that impair health-related quality of life (HRQoL). Existing evidence for HRQoL differences with respect to gender is conflicting.

Objective

To investigate potential gender differences in HRQoL for patients with CTCL.

Methods

We performed a cross-sectional study to assess HRQoL in patients with CTCL by partnering with the Cutaneous Lymphoma Foundation to distribute an electronic survey from February to April 2019.

Results

A total of 292 patient responses (66% women, mean age 57 years) were included in the analysis. Most of the cohort had early-stage (IA-IIA) (74%; 162/203) mycosis fungoides (MFs) (87%; 241/279), followed by Sézary syndrome (SS) (12%; 33/279). Women with CTCL experienced significantly worse HRQoL compared with men (Skindex-16: 51±26 vs. 36±26, P ≤ 0.001; FACT-G: 69±21 vs. 77±16, P = 0.005). This gender difference was present even when controlling for stage of disease. Women experienced worse HRQoL in all three of the Skindex-16 subscales (symptoms: β = 14.0, P ≤ 0.001; emotions: β = 15.1, P ≤ 0.001; functioning: β = 11.3, P = 0.006), but only two of the four FACT-G subscales (physical: β =-2.8, P ≤ 0.001; emotional: β = -2.0, P = 0.004).

Limitations

Due to the method of distribution of the survey, we were unable to estimate a participant response rate. Participants' diagnosis and stage were self-reported.

Conclusion

In this cohort women with CTCL experienced significantly worse HRQoL when compared to men. Additional studies are necessary to determine what factors contribute to this gender disparity.

Effects of high-intensity interval training on health-related quality of life in chronic lymphocytic leukemia: A pilot study

INTRODUCTION

Chronic lymphocytic leukemia (CLL) is the most common incurable leukemia/lymphoma in the United States. Individuals with CLL are at risk for disability, frailty, and cancer-specific complications that negatively affect health-related quality of life (HRQOL). High-intensity interval training (HIIT) and resistance training (RT) are safe and feasible for individuals with chronic diseases and when combined, they may be beneficial for reducing cancer-related fatigue, symptom burden, and global quality of life. However, no studies have examined the impact of HIIT or RT on HRQOL in CLL. The purpose of this study was to investigate the effects of a 12-week HIIT and RT (HIIT+RT) intervention on HRQOL in adults with treatment naïve CLL.

MATERIALS AND METHODS

Changes in HRQOL was a secondary outcome in this pilot study. Individuals with CLL (63.9 ± 8.5 yrs) were non-randomly assigned to 12 weeks of HIIT+RT or a control group. The HIIT+RT protocol consisted of three 30-min sessions/week of HIIT and two sessions/week of RT. The control group maintained usual daily activities. We assessed pre and post HRQOL using the Functional Assessment of Cancer Therapy-Lymphoma (FACT-Lym) questionnaire with domains of physical (PWB), social (SWB), emotional (EWB), functional (FWB), and general (FACT-G) well-being as well as a lymphoma-specific subscale (LymS). We used a two-way mixed analysis of variance to assess changes in HRQOL. We calculated effect size (ES) using Cohen's d.

RESULTS

Fifteen participants (HIIT+RT: n = 9; Control: n = 6) completed the study and questionnaire. Scores for FWB improved following HIIT+RT (21.7 ± 3.4 to 23.9 ± 3.2; ES = 1.38) compared to controls (25.7 ± 2.2 to 25.7 ± 2.3). The HIIT+RT group experienced clinically meaningful improvements in total FACT-Lym, FWB, FACT-G, and LymS. The control group had clinically meaningful changes only in LymS.

DISCUSSION

The large effect sizes and clinically meaningful improvements associated with 12 weeks of HIIT+RT support the potential benefits of this type of exercise program for FWB, lymphoma-specific symptoms, and general well-being in CLL. A future randomized trial with an adequately powered sample size is needed to evaluate these findings.

TRIAL REGISTRATION

NCT04950452.

Longitudinal assessment of quality of life in indolent non-Hodgkin lymphomas managed with active surveillance

There are limited data describing the impact of active surveillance on longitudinal health-related quality of life (HRQoL) in patients with indolent non-Hodgkin lymphomas (NHL). A cohort of untreated indolent NHL patients completed FACT-LYM questionnaires at 6, 12, 18, 24, and 36 months after diagnosis. Longitudinal FACT-LYM scores were analyzed by ANOVA and generalized linear mixed models. Indolent NHL scores were compared to norm general population scores. A total of 52 patients were identified, of which 46 (88%) remained on active surveillance at 36 months. There was no significant change in any of the FACT-LYM scores over 36 months. As compared to the general population, indolent NHL patients had higher, clinically meaningful scores in physical, functional, and social well-being, but not emotional well-being. Patients with indolent NHL on active surveillance have globally preserved HRQoL for up to 3 years after diagnosis. Emotional well-being continues to be an unmet need during active surveillance.

Health-related quality of life and treatment satisfaction in Chronic Lymphocytic Leukemia (CLL) patients on ibrutinib compared to other CLL treatments in a real-world US cross sectional study

The objective of this study was to describe real-world health-related quality of life (HRQoL) and treatment satisfaction of ibrutinib-treated patients with CLL compared to a reference group. This study was completed in two parts. The first portion (Norming Study) was a US online survey conducted to serve as a reference population. The Norming Study included a total of 139 patients with CLL, excluding those treated with ibrutinib: 64 were treatment naive (Tx naive), 36 were 1st line (1L), and 38 were in or had completed ≥2 lines (2L+) patients with CLL. The second portion (CLL Ibrutinib Study) included 1L and 2L+ ibrutinib patients with CLL treated for ≥6 months in which 118 patients (1L n = 88 and 2L+ n = 30) completed the study. Respondents completed demographic and clinical information and the following HRQoL surveys: (Short Form-12v2® Health Survey [SF-12v2], Functional Assessment of Cancer Therapy-General [FACT-G], FACT-Leukemia [FACT-Leu] Functional Assessment of Chronic Illness Therapy [FACIT]-Fatigue, and Cancer Therapy Satisfaction Questionnaire [CTSQ]). Higher scores indicate better HRQoL/treatment satisfaction. Differences in effect sizes between the two samples at the group level were calculated using Hedges' g. Medium to large positive effects were seen in the CLL Ibrutinib group on several measures compared to the Reference Study groups. The FACT-G total score was 89.2±11.1 for CLL Ibrutinib Study patients compared to 75.8±22.6 CLL Norming Tx naïve patients, 61.3±21.8 in 1L, and 61.7±20.7 in 2L+. Similar trends were seen with FACT-Leu total score and FACIT-Fatigue. CLL Ibrutinib Study patients scored higher on all CTSQ domain scores compared to the CLL Norming patients treated with other CLL therapies. We found that Ibrutinib-treatment had better HRQoL and treatment satisfaction compared to patients receiving other therapies, irrespective of line of therapy.

International validation of the EORTC QLQ-CLL17 questionnaire for assessment of health-related quality of life for patients with chronic lymphocytic leukaemia

Selecting the most appropriate chronic lymphocytic leukaemia (CLL) treatment is challenging. Patient-reported health-related quality of life (HRQoL) is therefore a critical aspect to consider. This international study by the European Organization for Research and Treatment of Cancer (EORTC) tested the psychometric properties of a newly developed measure for CLL patients: the EORTC QLQ-CLL17 to supplement the core questionnaire (EORTC QLQ-C30). Patients with CLL (n = 341) from 12 countries completed the QLQ-C30, QLQ-CLL17 and a debriefing questionnaire. Sociodemographic and clinical data were recorded from medical records. A high percentage (30%-66%) reported symptoms and/or worries (e.g. aches/pains in muscles, lack of energy and worry/fears about health). Confirmatory factor analysis showed an acceptable to good fit of the 17 items on the three scales (i.e. symptom burden, physical condition/fatigue and worries/fears about health and functioning). Completion took on average 8 min. Test-retest and convergent validity was demonstrated. The QLQ-CLL17 differentiated between patients with an Eastern Cooperative Oncology group (ECOG) performance of 0 versus 1-3 (p's < 0.01 and clinically relevant). The newly developed EORTC QLQ-CLL17 will increase sensitivity of HRQoL assessment in patients with CLL. Implementation of this questionnaire both in clinical research and practice will help to generate unique clinically relevant data to better inform CLL treatment decision-making.

Worsening Quality of Life in Indolent Non-Hodgkin Lymphoma and Chronic Lymphocytic Leukemia Patients in Active Surveillance: A 12-Month Longitudinal Study

INTRODUCTION

Newly diagnosed indolent non-Hodgkin lymphoma and chronic lymphocytic leukemia (NHL/CLL) patients are often monitored for disease progression to delay the impact of cancer-directed therapy on patients' quality of life. However, research on quality of life in patients under active surveillance versus in cancer-directed treatment has yielded mixed results. This study examined distress and quality of life in indolent NHL/CLL patients in active surveillance or cancer-directed treatment over the first-year post-diagnosis.

PATIENTS AND METHODS

Adult patients (≥21 years) with newly diagnosed indolent NHL/CLL completed electronic self-report measure of distress and quality of life every 4 months over the course of a year for a total of 4 surveys. Fisher's exact test and t-tests were used to examine demographic and disease differences between patients receiving different treatments. Mixed-effect models were also used to compare overall differences between treatment status over time, accounting for missing values.

RESULTS

The sample consisted of 64 patients with known baseline treatment status who did not change treatments over the course of the study. Total quality of life and physical, social and functional quality of life improved over time in patients receiving cancer-directed treatment and decreased over time in patients under active surveillance. Relative to patients in active treatment, overall, social, and functional quality of life in patients under surveillance changed more slowly over time.

DISCUSSION

Active surveillance may have negative implications for patient quality of life, despite that a common goal of active surveillance is to delay the impact of treatment (e.g., appointments, toxicities) on quality of life.

Improvements in Health-related Quality of Life and Symptoms in Patients With Previously Untreated Chronic Lymphocytic Leukemia: Final Results From the Phase II GIBB Study of the Combination of Obinutuzumab and Bendamustine

BACKGROUND

We evaluated health-related quality of life (HRQoL) in patients with chronic lymphocytic leukemia (CLL) receiving first-line chemoimmunotherapy in the GIBB single-arm, Phase II study of obinutuzumab plus bendamustine (BG).

MATERIALS AND METHODS

Patients received six 28-day cycles of BG and were followed for up to 27 months. HRQoL was assessed using the European Organization for Research and Treatment of Cancer Quality of Life Core 30 (EORTC QLQ-C30) and EORTC QLQ Chronic Lymphocytic Leukemia 16 (QLQ-CLL16) questionnaires. Scores were linear-transformed to a 100-point scale, with clinically meaningful responses defined as a ≥ 10-point change from baseline.

RESULTS

The patient-reported outcome (PRO) population comprised 98 patients (68.4% male; median age 61 years). EORTC QLQ-C30 global health status improvements were noted at all follow-up visits and were clinically meaningful 2 to 3 months after induction and at 3- and 27-months' follow-up. Clinically meaningful improvements were also observed for the EORTC QLQ-C30 role functioning, emotional functioning, fatigue and insomnia scales and the EORTC QLQ-CLL16 fatigue, disease symptoms and future health worries scales. Global health status was maintained throughout follow-up, and no clinically relevant deterioration in other HRQoL parameters was observed.

CONCLUSION

PRO data from the GIBB study show improved overall HRQoL in patients with CLL who received first-line chemoimmunotherapy with BG.

Health-related quality of life with fixed-duration venetoclax-obinutuzumab for previously untreated chronic lymphocytic leukemia: Results from the randomized, phase 3 CLL14 trial

Chronic lymphocytic leukemia (CLL)-related symptoms impair the well-being of patients, making improvement of health-related quality of life (QoL) a goal of treatment. The CLL14 trial demonstrated higher efficacy of fixed-duration venetoclax-obinutuzumab (Ven-Obi) compared to chlorambucil-obinutuzumab (Clb-Obi) in patients with previously untreated CLL. To assess patients' QoL, the following patient-reported outcomes (PRO) measures were assessed: the M.D. Anderson Symptom Inventory (MDASI) core instrument and CLL module and the EORTC Quality of Life Questionnaire Core 30 (EORTC QLQ-C30). At treatment start, physical functioning (mean 75.9 [standard deviation (SD) ± 20.1] in the Clb-Obi arm and 76.9 [±19.4] in the Ven-Obi arm), role functioning (73.6 [±27.86] and 72.6 [±26.9]) and GHS/QoL (63.6 [±21.0] and 60.3 [±20.5]) were comparable between treatment arms per EORTC QLQ-C30 scale scores. Baseline levels of physical and role functioning were maintained throughout treatment and follow-up, with no relevant improvement or deterioration. On average, patients treated with Ven-Obi showed a meaningful improvement of GHS/QoL during treatment and follow-up by at least eight points at cycle three, whereas improvement was delayed until cycle eight with Clb-Obi. According to MDASI scores, CLL symptoms (1.5 [±1.2] and 1.6 [±1.3]), core cancer symptoms (1.5 [±1.4] and 1.8 [±1.7]) and symptom interference (2.1 [±2.3] and 2.3 [±2.3]) were generally low and comparable between treatment arms at baseline and were maintained throughout treatment and follow-up. This analysis demonstrates that the higher efficacy of Ven-Obi is not associated with QoL impairment and that Ven-Obi achieves early relief of CLL-related symptoms in elderly unfit patients.

Rapid improvement in symptoms and physical function following ibrutinib initiation in chronic lymphocytic leukemia and the associated changes in plasma cytokines

A prospective pilot study was carried out on 34 CLL patients treated with ibrutinib, evaluating the effects on symptoms and physical function with changes in plasma exosomes (EXs), β2-microglobulin (β2M) and 26 plasma cytokines. The revised Edmonton Symptom Assessment Scale (ESAS-R) demonstrated moderate fatigue, shortness of breath and a sense of unwellness before treatment, which significantly improved within 2 weeks of starting ibrutinib. These changes were associated with a rapid improvement in sit-to-stand and 4 m walking speeds. The plasma levels of CCL11, IL-7, -8 and -10 dropped initially while the levels of TNF-α/-β, CCL3, CCL4, CCL17, and IL-16 continued to decline for 12 months. Despite the initial lymphocytosis, plasma β2M levels fell but no consistent change in plasma EXs occurred. Thus, ibrutinib can produce a rapid and sustained improvement in symptoms and physical function in CLL, associated with a decline in multiple plasma cytokines.

Assessment of the health utility of patients with leukemia in China

OBJECTIVES

This study aimed to assess the health utility of leukemia patients in China using the EQ-5D-5L, compare it with the population norms, and identify the potential factors associated with health utility.

METHODS

A hospital based cross-sectional survey was conducted in three tertiary hospitals from July 2015 to February 2016. A total of 186 patients with leukemia completed the EQ-5D-5L and their health utility scores were calculated using the Chinese value set. EQ-5D-5L utility and dimensions scores of leukemia patients were compared with China's population norms using Kruskal-Wallis test and chi square test. Potential factors associated with health utility were identified using Tobit regression.

RESULTS

The mean EQ-5D-5L utility scores of patients with leukemia, grouped by either gender or age, were significantly lower than those of the general population (p < 0.001). The same results were found for individual dimensions of EQ-5D-5L, where leukemia patients reported more health problems than the general population (p < 0.001). The utility score of leukemia patients was found to be significantly related to medical insurance, religious belief, comorbidities, social support and ECOG performance status.

CONCLUSION

This study indicated that leukemia patients have worse health status compared to the general population of China and that multiple factors affect the health utility of the patients. The utility scores reported in this study could be useful in future cost-utility analysis.

Disability, psychological distress and quality of life in relation to cancer diagnosis and cancer type: population-based Australian study of 22,505 cancer survivors and 244,000 people without cancer

BACKGROUND

Improved survival means that cancer is increasingly becoming a chronic disease. Understanding and improving functional outcomes are critical to optimising survivorship. We quantified physical and mental health-related outcomes in people with versus without cancer, according to cancer type.

METHODS

Questionnaire data from an Australian population-based cohort study (45 and Up Study (n = 267,153)) were linked to cancer registration data to ascertain cancer diagnoses up to enrolment. Modified Poisson regression estimated age- and sex-adjusted prevalence ratios (PRs) for adverse person-centred outcomes-severe physical functional limitations (disability), moderate/high psychological distress and fair/poor quality of life (QoL)-in participants with versus without cancer, for 13 cancer types.

RESULTS

Compared to participants without cancer (n = 244,000), cancer survivors (n = 22,505) had greater disability (20.6% versus 12.6%, respectively, PR = 1.28, 95%CI = (1.25-1.32)), psychological (22.2% versus 23.5%, 1.05 (1.02-1.08)) and poor/fair QoL (15.2% versus 10.2%; 1.28 (1.24-1.32)). The outcomes varied by cancer type, being worse for multiple myeloma (PRs versus participants without cancer for disability 3.10, 2.56-3.77; distress 1.53, 1.20-1.96; poor/fair QoL 2.40, 1.87-3.07), lung cancer (disability 2.81, 2.50-3.15; distress 1.67, 1.46-1.92; poor/fair QoL 2.53, 2.21-2.91) and non-Hodgkin's lymphoma (disability 1.56, 1.37-1.78; distress 1.20, 1.05-1.36; poor/fair QoL 1.66, 1.44-1.92) and closer to those in people without cancer for breast cancer (disability 1.23, 1.16-1.32; distress 0.95, 0.90-1.01; poor/fair QoL 1.15, 1.05-1.25), prostate cancer (disability 1.11, 1.04-1.19; distress 1.09, 1.02-1.15; poor/fair QoL 1.15, 1.08-1.23) and melanoma (disability 1.02, 0.94-1.10; distress 0.96, 0.89-1.03; poor/fair QoL 0.92, 0.83-1.01). Outcomes were worse with recent diagnosis and treatment and advanced stage. Physical disability in cancer survivors was greater in all population subgroups examined and was a major contributor to adverse distress and QoL outcomes.

CONCLUSIONS

Physical disability, distress and reduced QoL are common after cancer and vary according to cancer type suggesting priority areas for research, and care and support.

Reliability of a Novel Hematological Malignancy Specific Patient-Reported Outcome Measure: HM-PRO

BACKGROUND

Patients' experience of symptoms often goes undetected during consultation in an outpatient clinic, and the use of a patient-reported outcome measure (PRO) in such a setting could be useful to aid treatment decision-making. A new PRO measure, the HM-PRO (Hematological Malignancy Specific Patient-Reported Outcome Measure) has been recently developed to evaluate hematological malignancy (HM) patients' health-related quality of life (HRQoL) and their symptom experience in daily clinical practice as well as in research. The objectives of the study were to assess: the internal consistency of the scores for Part A (impact) and its four domains (physical behavior; social well-being; emotional behavior; and eating and drinking habits) and Part B (signs and symptoms); and the test-retest reliability of the individual items of the newly developed hematological malignancy specific composite measure, the HM-PRO.

METHODS

This was a prospective longitudinal observational study where 150 patients with different HMs and different stage of disease (male n = 98 (65.3%); mean age 64.9 ± 14.4 years, range 17.9-89.2 years; mean time since diagnosis 3.7 ± 4.9 years, range 0.04-25.8 years) completed the HM-PRO at baseline (assessment 1 at t1) and after 7 days (assessment 2 at t2). Data analysis was performed using IBMSPSS 23 statistical software.

RESULTS

The Cronbach's alpha estimates of the HM-PRO for both assessment points (t1 and t2) were above 0.9 for Part A, and above 0.8 for Part B, showing strong stability of the measurement. The level of agreement for the reproducibility between the two assessments, using intra-class correlation coefficients (ICC), was very strong with Part A: ICC = 0.93 (95% CI = 0.90-0.95), and Part B: ICC = 0.91 (0.88-0.93). The ICC for the four domains of Part A ranged from 0.85-0.91. The ICC was greater than 0.8 for overall score of Part A and Part B for all the 10 diagnoses, confirming strong reliability.

CONCLUSION

This study clearly indicates that the HM-PRO possesses strong test-retest reliability for both Part A and Part B. The Cronbach's alpha confirmed acceptable internal consistency. The extensive reliability testing described in this study supports the generic nature of the HM-PRO for use in hematological malignancies in both routine clinical practice, to aid treatment decisions, as well as in research.

Quality-of-life issues and symptoms reported by patients living with haematological malignancy: a qualitative study

Background

Our aim was to identify health-related quality-of-life (HRQoL) issues and symptoms in patients with haematological malignancies (HMs) and develop a conceptual framework to reflect the inter-relation between them.

Methods

A total of 129 patients with HMs were interviewed in a UK multicentre qualitative study. All interviews were audio recorded, transcribed and analysed using NVivo-11.

Results

Overall, 34 issues were reported by patients and were grouped into two parts: quality of life (QoL) and symptoms. The most prevalent HRQoL issues were: eating and drinking habits; social life; physical activity; sleep; and psychological well-being. Furthermore, most prevalent disease-related symptoms were: tiredness; feeling unwell; breathlessness; lack of energy; and back pain. The most prevalent treatment side effects were: tiredness; feeling sick; disturbance in sense of taste; and breathlessness.

Conclusions

Both HMs and their treatments have a significant impact on patients' HRQoL, in particular on issues such as job-role change, body image and impact on finances.

Health-related quality of life and economic burden of chronic lymphocytic leukemia in the era of novel targeted agents

OBJECTIVE

To quantify the health-related quality of life (HRQoL) and economic burden of chronic lymphocytic leukemia (CLL).

METHODS

Studies were searched through Embase, MEDLINE, PubMed, and Cochrane Library, as well as conference abstracts (1 January 2000-2 June 2019).

RESULTS

Overall, 12 and 17 primary studies were included in the HRQoL and economic burden reviews, respectively. Patients with CLL reported impairment in various quality of life domains when compared with healthy controls, including fatigue, anxiety, physical functioning, social functioning, depression, sleep disturbance, and pain interference. Key factors associated with a negative impact on the HRQoL burden of CLL included female gender, increased disease severity, and the initiation of multiple lines of therapy. Economic burden was assessed for patients with CLL based on disease status and the treatment regimen received. The main cost drivers related to CLL were outpatient and hospitalization-related costs, primarily incurred as a result of chemo/chemoimmunotherapy, adverse events (AEs), and disease progression. Treatment with targeted agents, i.e. ibrutinib and venetoclax, was associated with lower medical costs than chemoimmunotherapy, although ibrutinib was associated with some increased AE costs related to cardiac toxicities. Cost studies of targeted agents were limited by short follow-up times that did not capture the full scope of treatment costs.

CONCLUSIONS

CLL imposes a significant HRQoL and economic burden. Our systematic review shows that an unmet need persists in CLL for treatments that delay progression while minimizing AEs. Studies suggest targeted therapies may reduce the economic burden of CLL, but longer follow-up data are needed.

Gender difference in relation to depression and quality of life among patients with a primary brain tumor

Objective. –

We studied the relationship between depressive symptoms and quality of life (QOL) as well as functional status in primary brain tumor patients at recurrent measurements. Differences in QOL between depressive and non-depressive samples by gender were controlled for tumor characteristics and patients' psychosocial factors.

Materials and methods. –

The data consisted of 77 patients with a primary brain tumor, 30 males and 47 females. Depression of the patients was assessed by Beck Depression Inventory (BDI) and Crown-Crisp Experiential Index (CCEI), functional status by Karnofsky Performance scale (KPS) and QOL by Sintonen's 15D before tumor operation as well as at 3 months and at 1 year from surgical operation of the tumor.

Results.

The level of QOL in females was lower compared to that of males. Depression was the main predictor for worse QOL in the patients at all measurements. Depressive patients with a benign brain tumor had significantly worse QOL versus non-depressive ones.

Discussion and conclusion. –

Decreased QOL was strongly related to depression, especially among patients with a benign brain tumor. Further studies are needed to find whether sufficient depression therapy improves the QOL of patients.

Development of a Novel Hematological Malignancy Specific Patient-Reported Outcome Measure (HM-PRO): Content Validity

BACKGROUND

The quality of life of patients at all stages of hematological malignancy is greatly affected by the disease and its treatment. There is a wide range of health-related quality of life (HRQoL) issues important to these patients. Any new instrument developed to measure HRQoL of such patients should be content valid, i.e., the items should be comprehensively relevant to the patients and their health condition. The aim of the present study was to examine content validity of a hematological malignancy specific patient reported outcome measure (HM-PRO) developed for use in routine clinical practice.

METHODS

Following literature review and semi-structured interviews, the generated themes and sub-themes were discussed to develop the prototype version of the HM-PRO. A 4-step approach was used for content validation: initial testing and cognitive interviewing; item rating; content validity panel meeting; final field testing and cognitive interviewing. Additional questions related to patients' perception of recall period and preferred sentence structure (i.e., question or statement) of the items were also asked during cognitive interviews.

RESULTS

The content analysis of 129 transcribed semi-structured interviews resulted in the prototype version of the instrument consisting of 58 items grouped into two parts: Part A (impact/HRQoL - 34 items) and Part B (signs and symptoms - 24 items). The initial testing showed intra-class correlation coefficient (ICC) of >0.8 for both Part A and Part B. Item rating for language clarity, completeness, relevance, and response scale by experts and patients showed content validity index for scales average >0.8 for both Part A and Part B, except 0.64 for relevance for Part A by the patient panel. The final testing of the revised version of the instrument showed the Cronbach's alpha value of 0.91 for Part A and 0.76 for Part B, suggesting high internal consistency, and ICC of 0.91 for Part A and 0.76 for Part B. The recall period of "today" for Part-A and "last 3 days" for Part-B were the patients' preferred "recall period." Furthermore, the patients expressed preference to the HM-PRO items as statements.

CONCLUSION

The findings of this study confirm that the HM-PRO possesses a strong content validity, includes all the issues important to patients and is easy to read, understand and respond to spontaneously.

Acalabrutinib plus Obinutuzumab in Treatment-Naïve and Relapsed/Refractory Chronic Lymphocytic Leukemia

Acalabrutinib is a selective irreversible Bruton tyrosine kinase (BTK) inhibitor that does not affect IL2-associated tyrosine kinase or antibody-dependent cellular cytotoxicity, making it an attractive candidate for combination therapy with anti-CD20 antibodies. We investigated acalabrutinib plus obinutuzumab in a phase Ib/II study (NCT02296918) of patients with treatment-naïve or relapsed/refractory chronic lymphocytic leukemia (CLL). Nineteen treatment-naïve and 26 relapsed/refractory patients were treated with acalabrutinib (100 mg twice daily) until progression and obinutuzumab (cycle 1: 100 mg day 1, 900 mg day 2, 1000 mg days 8 and 15; cycles 2-6: 1,000 mg day 1). Grade 3/4 adverse events occurred in 71% of patients. Overall response rates were 95% (treatment-naïve) and 92% (relapsed/refractory). Thirty-two percent of treatment-naïve and 8% of relapsed/refractory patients achieved complete remission. At 36 months, 94% (treatment-naïve) and 88% (relapsed/refractory) were progression free. Acalabrutinib plus obinutuzumab was well tolerated, producing high and durable responses in treatment-naïve and relapsed/refractory CLL. SIGNIFICANCE: Rituximab plus the less selective BTK inhibitor ibrutinib has not shown benefit in CLL; however, the selective BTK inhibitor acalabrutinib plus the antibody-dependent cellular cytotoxicity-enhanced antibody obinutuzumab yielded durable responses that deepened over time in treatment-naïve and relapsed/refractory CLL, supporting the evaluation of this approach in larger, comparative studies in CLL.This article is highlighted in the In This Issue feature, p. 327.

Depression and anxiety in older patients with hematological cancer (70+) - Geriatric, social, cancer- and treatment-related associations

OBJECTIVES

Older patients are often underrepresented in clinical and epidemiological studies and the knowledge of the effect of hematologic cancer on mental health in the elderly is sparse. Objectives of our study are to provide information on depression and anxiety in older patients with hematological cancer (HCP), compared to a community sample (CS), and to investigate factors associated with depression and anxiety.

MATERIALS AND METHODS

We conducted a prospective study with interview assessments of HCP (ICD: C81 - C96) age ≥ 70 years to assess depressive symptoms (PHQ-9) and anxiety (GAD-7) in comparison to a CS matched by age and sex. Hierarchical Regression analysis was used to determine the association of depression and anxiety with quality of life (QoL) as well as geriatric, social, cancer- and treatment-related factors.

RESULTS

200 patients (response rate 50.5%, Mean age = 76 years, 64% male) and 225 citizens (response rate 44.5%) were interviewed. Compared to the CS, HCP showed significantly higher levels of depression. There was no difference in levels of anxiety between the two groups. Geriatric characteristics including limited mobility, need for care, comorbidity, as well as ongoing chemotherapy, lack of partnership, and low QoL were associated with depression. Anxiety in HCP was associated with detrimental social interaction, cognitive and emotional functioning, poor nutrition, and comorbidity.

CONCLUSIONS

Older patients with hematologic cancer are at high risk to experience depressive symptoms and low QoL. Health care professionals should assess geriatric symptoms and screen for depression to allow for early interventions and improve treatment outcomes.

Cancer-Specific Stress and Trajectories of Psychological and Physical Functioning in Patients With Relapsed/Refractory Chronic Lymphocytic Leukemia

Background

Chronic lymphocytic leukemia is the most prevalent adult leukemia. The disease is incurable with a cycling of treatment and relapse common. Little is known about the psychological and physical functioning of patients with relapsed/refractory chronic lymphocytic leukemia. Cancer-specific stress is an important individual difference variable that predicts psychological and physical outcomes.

Purpose

To examine cancer-specific stress at treatment initiation as a predictor of psychological and physical functioning trajectories in patients with relapsed/refractory chronic lymphocytic leukemia during the first 5 months of treatment.

Methods

Patients with relapsed/refractory chronic lymphocytic leukemia (N = 152) enrolled in a phase II clinical trial completed self-report measures at treatment initiation (baseline), 1, 2, and 5 months of treatment. Cancer-specific stress at baseline was examined as a predictor of psychological (cognitive-affective depressive symptoms, negative mood, mental health quality of life) and physical functioning (fatigue interference, sleep problems, physical health quality of life), controlling for demographic and treatment variables.

Results

Using multilevel modeling, higher baseline cancer-specific stress was related to worse psychological (cognitive-affective depressive symptoms, negative mood, mental health quality of life) and physical functioning (fatigue interference, sleep problems) at baseline and more rapid improvements during the next 5 months. Despite these improvements, higher baseline cancer-specific stress remained associated with poorer 5-month psychological, though not physical, functioning.

Conclusions

Findings suggest cancer-specific stress at treatment initiation may be a risk factor for poorer psychological functioning during treatment for patients with relapsed/refractory chronic lymphocytic leukemia.

Health-Related Predictors of Quality of Life in Cancer Patients in Saudi Arabia

Research on Saudi Arabian cancer patients is a priority at King Abdulaziz Medical City (KAMC), Riyadh, Saudi Arabia. Because there is limited research on the quality of life (QoL) of Saudi Arabian cancer patients, the aim of this study was to identify the predictors of the QoL in a sample of Saudis with cancer. In August 2016, a cross-sectional study was conducted on 438 patients with a variety of cancer types (145 breast, 109 colorectal, 38 leukemia, 45 lymphoma, and 99 other types) who attended the Oncology Outpatient Clinics at KAMC. Sociodemographics, clinical symptoms, and cancer treatments were collected for each patient. We used the SF-36 instrument to assess QoL. Of the cancer patients studied, 28.4% had a family history of cancer, and, according to subgroup analyses, the elderly, those lacking formal education, the unemployed, those diagnosed with Stage III/IV, and those with metastasis had significantly worse physical functions than the other cancer patients. According to multiple linear regression analyses, cancer patients who exercised regularly tended to have better physical function, emotional role function, vitality, social function, and general health (increase in SF-36 scores of 8.82, 9.75, 5.54, 6.66, and 4.97, respectively). Patients with first-year-after-cancer diagnosis tended to have poor emotional wellbeing, social function, and general health (decrease in SF-36 scores of 5.20, 7.34, and 6.12, respectively). Newly diagnosed cancer patients and patients who did not exercise tended to experience significantly poor QoL in several domains; thus, the effectiveness of exercise must be assessed in Saudi cancer patients as an intervention to improve QoL.

Improvement in Parameters of Hematologic and Immunologic Function and Patient Well-being in the Phase III RESONATE Study of Ibrutinib Versus Ofatumumab in Patients With Previously Treated Chronic Lymphocytic Leukemia/Small Lymphocytic Lymphoma

In the phase III study RESONATE, ibrutinib reduced the risk of progression and improved overall survival versus ofatumumab in previously treated patients with CLL/SLL. In this novel analysis of patient well-being including patient-reported outcomes, ibrutinib reduced disease burden while preserving parameters of hematologic and immunologic function in RESONATE. These results suggest that ibrutinib can improve quality of life while prolonging survival.

iwCLL guidelines for diagnosis, indications for treatment, response assessment, and supportive management of CLL

The previous edition of the consensus guidelines of the International Workshop on Chronic Lymphocytic Leukemia (iwCLL), published in 2008, has found broad acceptance by physicians and investigators caring for patients with CLL. Recent advances including the discovery of the genomic landscape of the disease, the development of genetic tests with prognostic relevance, and the detection of minimal residual disease (MRD), coupled with the increased availability of novel targeted agents with impressive efficacy, prompted an international panel to provide updated evidence- and expert opinion-based recommendations. These recommendations include a revised version of the iwCLL response criteria, an update on the use of MRD status for clinical evaluation, and recommendations regarding the assessment and prophylaxis of viral diseases during management of CLL.

Management of Persistent Angina After Myocardial Infarction Treated With Percutaneous Coronary Intervention: Insights From the TRANSLATE-ACS Study

BACKGROUND

Angina has important implications for patients' quality of life and healthcare utilization. Angina management after acute myocardial infarction (MI) treated with percutaneous coronary intervention (PCI) is unknown.

METHODS AND RESULTS

TRANSLATE-ACS (Treatment With Adenosine Diphosphate Receptor Inhibitors: Longitudinal Assessment of Treatment Patterns and Events After Acute Coronary Syndrome) was a longitudinal study of MI patients treated with percutaneous coronary intervention at 233 US hospitals from 2010 to 2012. Among patients with self-reported angina at 6 weeks post-MI, we described patterns of angina and antianginal medication use through 1 year postdischarge. Of 10 870 percutaneous coronary intervention-treated MI patients, 3190 (29.3%) reported angina symptoms at 6 weeks post-MI; of these, 658 (20.6%) had daily/weekly angina while 2532 (79.4%) had monthly angina. Among patients with 6-week angina, 2936 (92.0%) received β-blockers during the 1 year post-MI, yet only 743 (23.3%) were treated with other antianginal medications. At 1 year, 1056 patients (33.1%) with 6-week angina reported persistent angina symptoms. Of these, only 31.2% had been prescribed non-β-blocker antianginal medications at any time in the past year. Among patients undergoing revascularization during follow-up, only 25.9% were on ≥1 non-β-blocker anti-anginal medication at the time of the procedure.

CONCLUSIONS

Angina is present in one third of percutaneous coronary intervention-treated MI patients as early as 6 weeks after discharge, and many of these patients have persistent angina at 1 year. Non-β-blocker antianginal medications are infrequently used in these patients, even among those with persistent angina and those undergoing revascularization.

Health-related quality of life and patient-reported outcomes of ofatumumab plus chlorambucil versus chlorambucil monotherapy in the COMPLEMENT 1 trial of patients with previously untreated CLL

BACKGROUND

Patients diagnosed with chronic lymphocytic leukemia (CLL) are usually elderly and frequently have a number of comorbidities. Health-related quality of life (HRQoL) for these patients is of utmost importance and should be taken into consideration when assessing new treatment options. The combination of ofatumumab with chlorambucil has shown longer progression-free survival compared with chlorambucil alone. In this study, we aim to assess how this treatment combination affects patients' health-related quality of life and patient-reported symptoms.

MATERIAL AND METHODS

In this open-label phase III trial, patients with previously untreated CLL for whom fludarabine-based treatment was contra-indicated, were randomized 1:1 to receive oral chlorambucil (10 mg/m²) on Days 1-7 of a 28-day treatment cycle or to receive chlorambucil by this schedule plus intravenous ofatumumab (Cycle 1: 300 mg on Day 1 and 1000 mg on Day 8; subsequent cycles: 1000 mg Day 1) for 3-12 cycles. The EORTC QLQ-C30 and QLQ-CLL16 questionnaires were administered to patients before and during treatment, in follow-up and at the time of disease progression. The primary specified patient-reported outcomes were HRQoL and fatigue.

RESULTS

Patient-reported improvements from baseline in Global Health Status (GHS)/HRQoL scores and fatigue scores were recorded during treatment with both chlorambucil monotherapy and ofatumumab in combination with chlorambucil. There were no significant differences between the two treatment arms for GHS/HRQoL (p = 0.667) or fatigue (p = 0.103). Following treatment, numerical improvements to GHS/HRQoL and fatigue scores were reported, with no significant differences between the two treatment arms.

CONCLUSION

Small but detectable improvements in patients' quality of life were reported as a result of treatment. The addition of ofatumumab to chlorambucil did not negatively impact HRQoL. Quality of life was maintained in the months following treatment.

Individual differences in physical symptom burden and psychological responses in individuals with chronic lymphocytic leukemia

Chronic lymphocytic leukemia (CLL) is an incurable illness, with some patients requiring no treatment until disease progression. Burden from physical symptoms has been associated with depression, anxiety, and stress in cancer patients. Additionally, patient factors, i.e., individual differences, have been associated with worse psychological outcomes. There are few psychological studies of CLL, with no examination of individual differences. A cross-sectional design studied the covariation of symptom burden with depressive and anxiety symptoms and cancer-specific stress, and tested patients' individual differences as predictors and as moderators. CLL patients (N = 112) receiving active surveillance participated. They were Caucasian (100 %) and predominately male (55 %) with a mean age of 61; most (62.5 %) had stage 0 disease. A composite measure of physical symptom burden (CLL symptoms, fatigue, pain, impaired functional status) was tested as a predictor of psychological responses. Individual differences in psychiatric history and social support were tested as moderators. Using multiple linear regression, greater symptom burden covaried with higher levels of depressive and anxiety symptoms and cancer stress (ps < .05). Those with a psychiatric history, low social support, and low relationship satisfaction with one's partner reported greater symptom burden and more psychological symptoms and stress (ps < .05). Findings suggest that CLL patients in surveillance with a psychiatric history and/or low social support are at risk for greater distress when coping with high symptom burden. These new data clarify the experience of CLL surveillance and identify characteristics of patients with heightened risk for symptom burden, stress, and anxiety or depressive symptoms.

What is known and unknown about chemotherapy-related cognitive impairment in patients with haematological malignancies and areas of needed research

Cancer-related cognitive impairment (CRCI) is an important clinical problem for cancer patients and survivors. In this review, we summarize studies investigating the occurrence of impaired cognition in patients with haematological malignancies. Most published studies focus on survivors of childhood acute lymphoblastic leukaemia and primary central nervous system lymphoma. We also discuss studies conducted in acute myeloid leukaemia, myelodysplastic syndromes, chronic myeloid leukaemia, Hodgkin lymphoma (HL), non-HL and chronic lymphocytic leukaemia. Although research in this area is still emerging, it appears that a subset of chemotherapy-treated haematological malignancy survivors experience CRCI. Future research should focus on expanding the literature reviewed here with larger studies appropriately powered to assess cognition via objective and subjective measures in a longitudinal fashion to tease apart the impact of disease and the various forms of cancer treatment.

Economic Burden and Quality-of-Life Effects of Chronic Lymphocytic Leukemia: A Systematic Review of the Literature

BACKGROUND

Chronic lymphocytic leukemia (CLL) is the most prevalent type of leukemia in the Western hemisphere. The disease affects quality of life (QOL) and poses an economic burden on patients, payers, and society. The objective of this review was to quantify the economic burden and quality-of-life effects and identify the gaps that should be addressed by future research.

METHODS

Free-text and subject heading searches in MEDLINE, EMBASE, the Cochrane Library, the University of York Centre for Reviews and Dissemination Database, and the Web of Science Core Collection database were conducted to identify observational and interventional studies reporting costs and/or quality-of-life effects published up to 2 October 2015. Studies were included irrespective of whether they were conducted prospectively or retrospectively. The focus population consisted of adult patients aged 18 years or older affected by any stage of CLL. Studies were included regardless of whether the underlying population was treated at baseline or not. Risk of bias was assessed using a quality checklist developed by the Effective Public Health Practice Project for (randomized) controlled trials, cohort studies, and cross-sectional studies. Economic evaluations were rated using a checklist developed by Stuhldreher et al. (Int J Eat Disord 45:476-91, 2012).

RESULTS

From 2451 records identified, 27 studies were found to be eligible for inclusion. Studies were heterogeneous with respect to methodology, perspective, and data used. Annual direct costs per person ranged from US$4491 in Germany to US$43,913 in the USA. The share of costs attributable to drug treatment varied between 26.2 and 79 %. Indirect costs amounted to US$4208. Severity of disease was a predictor for quality of life, whereas differences by age and sex were mainly present in subdomains. Comparisons of treated and untreated populations resulted in an increase of quality of life in favor of treated populations in the long-term perspective. Differences between treatments were small. Consequently, cost effectiveness in decision-analytic models did not depend on whether quality of life or survival are used to describe the benefits of treatment.

CONCLUSIONS

Although the quantity and the quality of health economic and quality-of-life evidence have substantially increased, there is still a need for studies that take a patient or societal perspective. Factors that influence costs and the quality of life of patients seem to be well-established, while longitudinal lifetime cost studies at the population level are still scarce.

Quality of life of patients with chronic lymphocytic leukaemia in the Netherlands: results of a longitudinal multicentre study

Purpose

To describe the health-related quality of life (HRQoL) of an unselected population of patients with chronic lymphocytic leukaemia (CLL) including untreated patients.

Methods

HRQoL was measured by the EORTC QLQ-C30 including the CLL16 module, EQ-5D, and VAS in an observational study over multiple years. All HRQoL measurements per patient were connected and analysed using area under the curve analysis over the entire study duration. The total patient group was compared with the general population, and three groups of CLL patients were described separately, i.e. patients without any active treatment (“watch and wait”), chlorambucil treatment only, and patients with other treatment(s).

Results

HRQoL in the total group of CLL patients was compromised when compared with age- and gender-matched norm scores of the general population. CLL patients scored statistically worse on the VAS and utility score of the EQ-5D, all functioning scales of the EORTC QLQ-C30, and the symptoms of fatigue, dyspnoea, sleeping disturbance, appetite loss, and financial difficulties. In untreated patients, the HRQoL was slightly reduced. In all treatment stages, HRQoL was compromised considerably. Patients treated with chlorambucil only scored worse on the EORTC QLQ-C30 than patients who were treated with other treatments with regard to emotional functioning, cognitive functioning, bruises, uncomfortable stomach, and apathy.

Conclusions

CLL patients differ most from the general population on role functioning, fatigue, concerns about future health, and having not enough energy. Once treatment is indicated, HRQoL becomes considerably compromised. This applies to all treatments, including chlorambucil, which is considered to be a mild treatment.

Haematological cancer and quality of life: a systematic literature review

The aim of this study is to examine the impact of haematological cancers on quality of life (QoL). A review of the international literature was conducted from the databases ‘PsycInfo' and 'Medline' using the keywords: 'haematological cancer', 'quality of life', 'physical', 'psychological', 'social', 'vocational', 'professional', 'economic', 'cognitive', and 'sexual'. Twenty-one reliable studies were analysed. Among these studies, 12 showed that haematological cancer altered overall QoL, 8 papers found a deterioration of physical dimension, 8 papers reported on functional and role dimensions, 11 papers reported on the psychological component and 9 on the social component. Moreover, one study and two manuscripts, respectively, reported deteriorated sexual and cognitive dimensions. Our review demonstrates that the different dimensions of QoL are deteriorated by haematological malignancies and, probably, by the side effects of treatment.

Predictors of quality of life in 102 patients with treated Cushing's disease

OBJECTIVE

To identify predictors for quality of life (QoL) in treated Cushing's disease (CD) and quantify patients' assessment of their disease status.

CONTEXT

Significant reductions in QoL exist in CD patients despite treatment. Identifying predictors of QoL is paramount to the long-term management of these patents.

DESIGN

A cross-sectional study was conducted of patients with treated CD. Patients completed a medical history questionnaire and three validated quality of life assessments: Cushing's QoL Questionnaire (CushingQoL), Hospital Anxiety and Depression Scale (HADS) and Nottingham Health Profile (NHP).

PATIENTS

102 patients (75·7% female, mean time since surgery 7·4 years) with treated CD were included.

MEASUREMENTS

Patients were categorized by biochemical and self-identified disease status. Mean CushingQoL, anxiety and depression scores were compared by unpaired t-tests. Multiple linear regressions were performed on the whole cohort to assess for predictors of impaired QoL.

RESULTS

Ninety-two per cent of the cohort met criteria for biochemical remission, but only 80·4% felt they had achieved remission. Among those with biochemical remission, those who also self-identified as being in remission had higher CushingQoL scores than those who self-identified as having persistent disease (P = 0·042). Anxiety (P = 0·032) and depression (P = 0·018) scores were lower, and CushingQoL scores were higher (P = 0·05) in patients who self-identified as being in remission compared to persistence. Recovery time, BMI, gender and age were also predictors for QoL.

CONCLUSION

Our study identifies the discordance that can exist between biochemical and self-assessed disease status and demonstrates its impact on QoL in patients with CD. These findings highlight the importance of incorporating patients' disease perceptions in their management.

Impact of active surveillance, chlorambucil, and other therapy on health-related quality of life in patients with CLL/SLL in the Netherlands

As survival of patients with chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) increases and the number of patients who live long rises, health-related quality of life (HRQoL) becomes a relevant endpoint. Few studies investigated this, mainly as a secondary endpoint in randomized clinical trials where patients with early stage CLL/SLL, and elderly/frail patients were underrepresented. The aim of our study was to assess HRQoL in a population-based setting, including these previously underrepresented patients. Out of 175 patients diagnosed with CLL/SLL between 2004 and 2011, 136 (78 %) returned the HRQoL questionnaire. The outcomes were compared to an age- and sex-matched norm population. Detailed data on stage and treatment were extracted from a population-based hematological registry (PHAROS). Patients ever treated for CLL/SLL reported significantly poorer HRQoL than the norm population (p < 0.01 with large clinically important differences. Interestingly, no differences were observed between the norm population and patients under active surveillance. In contrast to our hypothesis, patients treated with chlorambucil reported the lowest HRQoL scores. Drastic, long-lasting negative effects of starting treatment on HRQoL cannot be excluded, whereas active surveillance does not seem to provoke worrying, anxiety, or depressive symptoms. Further elaborate research into the impact of starting therapy on HRQoL is needed, especially in patients that are underrepresented in most clinical trials, and thoroughly consider its results during revision of treatment guidelines.

Association of health-related quality of life with gender in patients with B-cell chronic lymphocytic leukemia

PURPOSE

This analysis examined associations between gender and health-related quality of life (HRQOL) in patients with B-cell chronic lymphocytic leukemia (CLL) as they initiate therapy for CLL outside the clinical trial setting.

METHODS

Baseline data were collected as part of Connect® CLL Registry, a prospective observational study initiated in community, academic, and government centers. Patient demographics and clinical characteristics were provided by clinicians. Patients reported HRQOL using the Brief Fatigue Inventory (BFI), EQ-5D, and Functional Assessment of Cancer Therapy-Leukemia (FACT-Leu). Mean scores were analyzed, with statistical significance of differences determined by ANOVA. Multivariate analysis also considered age and line of therapy.

RESULTS

Baseline HRQOL data were available for 1,140 patients: 710 (62 %) men and 430 (38 %) women from 161 centers. Patients were predominantly white (89 %) with mean age 69 ± 11 years. Women reported significantly worse global fatigue (P <0.0001), fatigue severity (P <0.0001), and fatigue-related interference (P = 0.0005) versus men (BFI). Pain/discomfort (P = 0.0077), usual activities (P = 0.0015), and anxiety/depression (P = 0.0117) were significantly worse in women than in men (EQ-5D). With women reporting a better social/family score (P = 0.0238) and men reporting a better physical score (P = 0.0002), the mean FACT-G total score did not differ by gender. However, the mean FACT-Leu total score was better among men versus women (P = 0.0223), primarily because the mean leukemia subscale score was significantly better among men (P <0.0001). Multivariate analysis qualitatively confirmed these findings.

CONCLUSIONS

Connect® CLL Registry results indicate that significant differences exist in certain HRQOL domains, as women reported greater levels of fatigue and worse functioning in physical domains.
