Quality of life in patients with multiple myeloma and malignant lymphoma undergoing autologous progenitor stem cell transplantation: The effect of selected psychosocial and health aspects on quality of life: A retrospective analysis

EQ-5D-Derived Health State Utility Values in Hematologic Malignancies: A Catalog of 796 Utilities Based on a Systematic Review

OBJECTIVES

We performed a systematic review of health state utility values (HSUVs) obtained using the EQ-5D questionnaire for patients with hematologic malignancies.

METHODS

The following databases were searched up to September 2018: MEDLINE, EMBASE, The Cochrane Library, and the EQ-5D publications database on the EuroQol website. Additional references were extracted from reviewed articles. Only studies presenting EQ-Index results were incorporated. In view of the heterogeneity across the included publications, we limited ourselves to a narrative synthesis of original HSUVs found.

RESULTS

Fifty-nine studies (described in 63 articles) met the inclusion criteria. Data from 21 635 respondents provided 796 HSUV estimates for hematologic malignancy patients. EQ-Index scores ranged from -0.025 to 0.980. The most represented area was multiple myeloma (4 studies, 11 112 patients, and 249 HSUVs). In clinical areas such as chronic myeloid leukemia, acute myeloid leukemia, chronic lymphocytic leukemia, non-Hodgkin lymphoma, and mantle cell lymphoma, we described over 50 health utilities in each. In contrast, we identified only 13 HSUVs (based on 4 studies and the data of 166 patients) for Hodgkin lymphoma. Areas without EQ-5D-based health utilities comprised: polycythemia vera, primary myelofibrosis, essential thrombocythemia, mastocytosis, myeloid sarcoma, chronic myelomonocytic, eosinophilic leukemia, and neutrophilic leukemia.

CONCLUSIONS

There is a wide range of HSUVs available for hematologic cancer patients with different indications. The review provides a catalog of utility values for use in cost-effectiveness models for hematologic malignancies.

Health-related quality of life in Croatian general population and multiple myeloma patients assessed by the EORTC QLQ-C30 and EORTC QLQ-MY20 questionnaires

Background The impact of disease and treatment on the patient's overall well-being and functioning is a topic of growing interest in clinical research and practice. The aim of this study is to obtain reference data on quality of life of Croatian general population. Further, we aim to assess the impact of the disease and its primary systemic treatment on their health related quality of life (HrQoL) in multiple myeloma (MM) patients. Patients and methods Participants for the first part of the study were randomly selected from adult Croatian population. In the clinical part of the study MM patients were included as prospectively diagnosed within two years in two major Croatian haematological centres. The EORTC QLQ-C30 in both trials and QLQ-MY20 in MM patients only were applied for HrQoL assessment. Results Gender, age and place of residence have great impact on quality of life scores in Croatian population. The MM patients at the time of diagnosis have lower QLQ-C30 scores for global quality of life, functional and symptom scale scores, as well as single items. The type of disease followed by the choice of therapy options are important HrQoL determinants. Conclusions The norm values available now for Croatian population will help to interpret HrQoL for clinicians and aid in planning cancer care interventions. This study identified treatment effect consistent with those from other observational studies and provided new data on HrQoL across two different treatment choices for MM patients.

Prevalence of symptoms in patients with multiple myeloma: a systematic review and meta-analysis

OBJECTIVES

Multiple myeloma (MM) is an incurable haematological disease. Due to novel agents, overall survival has improved in this group, yet there are no systematic reviews to understand the symptom profiles resulting from disease and treatment-related toxicities. We aimed to synthesise data on the prevalence of symptoms in patients with MM.

METHODS

A systematic database and grey literature search were conducted in six databases. Random-effects meta-analysis with inverse variance weighting to pool prevalence data was performed.

RESULTS

Thirty-six studies were included of which 34 studies (N = 3023) provided data for meta-analysis. Twenty-seven distinct symptoms were reported, with the majority of studies focusing on pain (n = 27), fatigue (n = 19) and problems with functioning (n = 15). The most prevalent symptoms were fatigue (98.8%, 95% CI 98.1-99.2%), pain (73%, 39.9-91.7), constipation (65.2%, 22.9-92.2) and tingling in the hands/feet with 53.4% (0.4-99.7). The most common problems were decreased physical functioning (98.9%, 98.2-99.3), decreased cognitive functioning (80.2%, 40-96.1) and financial difficulties (78.4%, 39.1-95.4). These problems were present in newly diagnosed to advanced disease stage.

CONCLUSIONS

Optimal quality of life and good symptom management in this incurable disease can only be achieved by routinely assessing symptoms throughout the disease trajectory.

EQ-5D in Central and Eastern Europe: 2000-2015

OBJECTIVE

Cost per quality-adjusted life year data are required for reimbursement decisions in many Central and Eastern European (CEE) countries. EQ-5D is by far the most commonly used instrument to generate utility values in CEE. This study aims to systematically review the literature on EQ-5D from eight CEE countries.

METHODS

An electronic database search was performed up to 1 July 2015 to identify original EQ-5D studies from the countries of interest. We analysed the use of EQ-5D with respect to clinical areas, methodological rigor, population norms and value sets.

RESULTS

We identified 143 studies providing 152 country-specific results with a total sample size of 81,619: Austria (n = 11), Bulgaria (n = 6), Czech Republic (n = 18), Hungary (n = 47), Poland (n = 51), Romania (n = 2), Slovakia (n = 3) and Slovenia (n = 14). Cardiovascular (21 %), neurologic (17 %), musculoskeletal (15 %) and endocrine, nutritional and metabolic diseases (13 %) were the most frequently studied clinical areas. Overall, 112 (78 %) of the studies reported EQ VAS results and 86 (60 %) EQ-5D index scores, of which 27 (31 %) did not specify the applied tariff. Hungary, Poland and Slovenia have population norms. Poland and Slovenia also have a national value set.

CONCLUSIONS

Increasing use of EQ-5D is observed throughout CEE. The spread of health technology assessment activities in countries seems to be reflected in the number of EQ-5D studies. However, improvement in informed use and methodological quality of reporting is needed. In jurisdictions where no national value set is available, in order to ensure comparability we recommend to apply the most frequently used UK tariff. Regional collaboration between CEE countries should be strengthened.

Are psychosocial factors associated with quality of life in patients with haematological cancer? A critical review of the literature

BACKGROUND

Haematological cancers differ from other cancers mainly with regard to treatment strategies: surgery is used for diagnostic purposes but rarely for treatment, whereas chemotherapy is of central importance and, in some cases, cures patients. This article reviews studies that examine the relationships between psychosocial factors and quality of life (QoL) in haematological cancer patients.

METHODS

A review of the literature was conducted from the databases 'PsycInfo', 'Medline' and 'Science Direct' using the keywords 'lymphoma', 'leukaemia', 'myeloma', 'quality of life', 'psychosocial factors', 'coping', 'social support', 'personality', 'anxiety,' 'depression', 'locus of control' and 'alexithymia'.

RESULTS

Fourteen studies were analysed. One study found positive relationships between sense of coherence and health-related QoL, whereas another showed a positive link between self-esteem and QoL. Another study suggested that a high external health locus of control was related to a better QoL. Fighting spirit had a positive impact on QoL for two studies, and helplessness-hopelessness was positively related to emotional distress in one study. Two studies indicated the relationships between emotional distress and QoL. Satisfaction with information about disease determined emotional distress in another study. Social support, general health perceptions, global meaning or spirituality were found to improve QoL in four other reports.

CONCLUSION

Literature about the relationships between psychosocial factors and QoL is lacking. Sense of coherence, self-esteem and health locus of control, coping strategies, social support, global meaning or emotional distress are associated with QoL. Results concerning coping and social support should be interpreted with caution because of level II evidence in studies.
