Cheng LJ, Pan T, Chen LA, Cheng JY, Mulhern B, Devlin N, Luo N. The Ceiling Effects of EQ-5D-3L and 5L in General Population Health Surveys: A Systematic Review and Meta-analysis. VALUE IN HEALTH : THE JOURNAL OF THE INTERNATIONAL SOCIETY FOR PHARMACOECONOMICS AND OUTCOMES RESEARCH 2024:S1098-3015(24)00091-3. [PMID: 38467187 DOI: 10.1016/j.jval.2024.02.018] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/22/2023] [Revised: 02/13/2024] [Accepted: 02/28/2024] [Indexed: 03/13/2024]
Abstract
OBJECTIVES This review aims to examine the ceiling effects of EQ-5D-3L (3L) and EQ-5D-5L (5L) in general adult populations and identify the factors influencing these effects. METHODS We searched 8 databases for observational studies published in English from inception to 24 July 2023. Ceiling effects were calculated by dividing the number of participants reporting full health at dimension or profile level by the total sample size. Subgroup analysis and meta-regression using the metafor package in R software were performed. RESULTS We identified 94 studies from 70 articles, including 4 543 647 adults across 37 countries. The global pooled proportion of individuals reporting full health ("11111") was 56% (95% CI 51%-62%) for 3L and 49% (95% CI 44%-54%) for 5L. The self-care dimension showed the highest ceiling effects (3L: 97%; 5L: 94%), whereas pain/discomfort had the lowest (3L: 69%; 5L: 60%). The ceiling effects in East/South-East Asia were higher than in Europe by 25% (95% CI 18%-32%) in 3L and 9% (95% CI -2%-20%) in 5L. Adjusting for mean age and proportion of males, significant regional differences persisted in the overall profile level of 3L, in all 3L dimensions (except for self-care), and 5L dimensions (except for pain/discomfort and anxiety/depression). CONCLUSIONS This review highlights significant ceiling effects in the EQ-5D, especially in Asian populations. The 5L version exhibited fewer ceiling effects than the 3L, indicating its superiority for general population surveys. Further research is crucial to understand the disparities in self-reported health outcomes between Asians and other populations.

Abstract
BACKGROUND AND AIMS HCC is a leading cause of mortality in patients with advanced liver disease and is associated with significant morbidity. Despite multiple available curative and palliative treatments, there is a lack of systematic evaluation of patient-reported outcomes (PROs) in HCC. APPROACH AND RESULTS The American Association for the Study of Liver Diseases Practice Metrics Committee conducted a scoping review of PROs in HCC from 1990 to 2021 to (1) synthesize the evidence on PROs in HCC and (2) provide recommendations on incorporating PROs into clinical practice and quality improvement efforts. A total of 63 studies met inclusion criteria investigating factors associated with PROs, the relationship between PROs and survival, and associations between HCC therapy and PROs. Studies recruited heterogeneous populations, and most were cross-sectional. Poor PROs were associated with worse prognosis after adjusting for clinical factors and with more advanced disease stage, although some studies showed better PROs in patients with HCC compared to those with cirrhosis. Locoregional and systemic therapies were generally associated with a high symptom burden; however, some studies showed lower symptom burden for transarterial radiotherapy and radiation therapy. Qualitative studies identified additional symptoms not routinely assessed with structured questionnaires. Gaps in the literature include lack of integration of PROs into clinical care to guide HCC treatment decisions, unknown impact of HCC on caregivers, and the effect of palliative or supportive care quality of life and health outcomes. CONCLUSION Evidence supports assessment of PROs in HCC; however, clinical implementation and the impact of PRO measurement on quality of care and longitudinal outcomes need future investigation.

Abstract
To demonstrate the measurement properties of the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Hepatocellular Carcinoma 18-question module (EORTC QLQ-HCC18) within a previously treated, unresectable hepatocellular carcinoma (HCC) clinical trial population that was distinct from the published QLQ-HCC18 validation population. Analyses were conducted using data from BGB-A317-208, an open label, international, clinical trial assessing efficacy and safety of the monoclonal antibody tislelizumab in adult HCC patients. The EORTC Quality of Life Questionnaire Core 30 (EORTC QLQ-C30) and QLQ-HCC18 instruments were assessed at baseline and weeks 3 and 9 follow-up visits. Per US Food and Drug Administration guidance, psychometric validation of the QLQ-HCC18 included reliability (internal consistency and test–retest), construct validity (convergent and discriminant validity and known-groups validity), ability to detect change, and meaningful within-patient change (MWPC). Known-groups validity and MWPC analyses were also stratified on several pre-defined subgroups. A total of 248 patients were included. Only the QLQ-HCC18 fatigue, nutrition, and index domains demonstrated acceptable internal consistency; acceptable test–retest reliability was found for fatigue, body image, nutrition, pain, sexual interest, and index domains. The QLQ-HCC18 fatigue domain achieved the pre-specified criterion defining acceptable convergent and discriminant validity for 13 of 16 correlations, whereas the index domain achieved the pre-specified criterion for 14 of 16 correlations. Clear differentiation of the QLQ-HCC18 change scores between improvement and maintenance anchor groups were observed for body image, fatigue, pain, and index domains, whereas differentiation between deterioration and maintenance anchor groups were observed for fever and fatigue domains. MWPC point estimates defining improvement for the QLQ-HCC18 fatigue and index domains were −7.18 and −4.07, respectively; MWPC point estimates defining deterioration were 5.34 and 3.16, respectively. The EORTC QLQ-HCC18 fatigue and index domains consistently demonstrated robust psychometric properties, supporting the use of these domains as suitable patient-reported endpoints within a previously treated, unresectable HCC patient population.

Health-related quality of life in primary hepatic cancer: a systematic review assessing the methodological properties of instruments and a meta-analysis comparing treatment strategies. Qual Life Res 2021; 30:2429-2466. [PMID: 34283381 PMCID: PMC8405513 DOI: 10.1007/s11136-021-02810-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 02/23/2021] [Indexed: 11/25/2022]
Abstract
PURPOSE Patient-reported outcomes including health-related quality of life (HRQoL) are important oncological outcome measures. The validation of HRQoL instruments for patients with hepatocellular and cholangiocellular carcinoma is lacking. Furthermore, studies comparing different treatment options in respect to HRQoL are sparse. The objective of the systematic review and meta-analysis was, therefore, to identify all available HRQoL tools regarding primary liver cancer, to assess the methodological quality of these HRQoL instruments and to compare surgical, interventional and medical treatments with regard to HRQoL. METHODS A systematic literature search was conducted in MEDLINE, the Cochrane library, PsycINFO, CINAHL and EMBASE. The methodological quality of all identified HRQoL instruments was performed according to the COnsensus-based Standards for the selection of health status Measurements INstruments (COSMIN) standard. Consequently, the quality of reporting of HRQoL data was assessed. Finally, wherever possible HRQoL data were extracted and quantitative analyses were performed. RESULTS A total of 124 studies using 29 different HRQoL instruments were identified. After the methodological assessment, only 10 instruments fulfilled the psychometric criteria and could be included in subsequent analyses. However, quality of reporting of HRQoL data was insufficient, precluding meta-analyses for 9 instruments. CONCLUSION Using a standardized methodological assessment, specific HRQoL instruments are recommended for use in patients with hepatocellular and cholangiocellular carcinoma. HRQoL data of patients undergoing treatment of primary liver cancers are sparse and reporting falls short of published standards. Meaningful comparison of established treatment options with regard to HRQoL was impossible indicating the need for future research.

Abstract
PURPOSE Adults with hepatocellular carcinoma (HCC) have a high symptom burden. Their quality of life (QOL) has been shown to be significantly impacted by both the disease and its treatment, adding to the high symptom burden that these patients experience. The primary aims of this paper are as follows: (1) to identify how QOL is being defined in HCC literature and (2) to identify how QOL is being measured in the HCC literature using Ferrell's model of QOL. METHODS A systematic review was completed of relevant studies published after 2014, using PubMed, CINHAL, and PsycInfo. Relevant studies were reviewed by 2 reviewers using PRISMA guidelines. RESULTS From a total of 1312 papers obtained in the initial database search, 30 met inclusion criteria and are included in this review. From the included articles, 10% included a definition of QOL and 3% addressed the spiritual domain of QOL. Majority of study participants were in the early stage of HCC, though the majority of adults with HCC are diagnosed in the advanced stage. Only 3% of included studies included greater than 22% population of advanced stage of HCC. CONCLUSION The results of this systematic review demonstrate the need for future research into QOL in the advanced stage of QOL. It also identified gap in the literature concerning the definition of QOL in HCC and the spiritual domain of QOL in HCC.

Abstract
We reviewed all studies assessing the health-related quality of life (HRQoL) in patients with hepatocellular carcinoma (HCC) between 2009 and 2018 (n = 45). Most studies assessed HRQoL as an outcome, and evaluated or compared the HRQoL of HCC patients depending on the type of treatment or stage of disease. HCC patients had a worse HRQoL than the general population, including in those with early-stage HCC. Patients commonly experienced pain, fatigue, sleep disturbance, distress, and lack of appetite, and these symptoms remained problematic even a few years after treatment. TNM classification of malignant tumors stage, tumor stage, presence of cirrhosis, being Asian, being female, living alone, or being unemployed were associated with a poor HRQoL. While recent studies have included a more diverse patient population, various topics, and different study designs, there were limited studies on supportive interventions. Given the increase in HCC cases and HCC survivors, addressing the HRQoL of HCC patients requires more attention.

Abstract
Hepatocellular carcinoma (HCC) is a major cause of cancer-related mortality worldwide. Around half of patients with HCC will receive systemic therapies during their life span. The pivotal positive sorafenib trial and regulatory approval in 2007 was followed by a decade of negative studies with drugs leading to marginal antitumoral efficacy, toxicity, or trials with a lack of enrichment strategies. This trend has changed over the last 2 years with several compounds, such as lenvatinib (in first-line) and regorafenib, cabozantinib, ramucirumab and nivolumab (in second-line), showing clinical benefit. These successes came at a cost of increasing the complexity of decision-making, and ultimately, impacting the design of future clinical trials. Nowadays, life expectancy with single active agents has surpassed the threshold of 1 year and sequential strategies have provided encouraging outcomes. Overall survival (OS) remains the main endpoint in phase III investigations, but as in other solid tumours, there is a clear need to define surrogate endpoints that both reliably recapitulate survival benefits and can be assessed before additional efficacious drugs are administered. A thorough analysis of 21 phase III trials published in advanced HCC demonstrated a moderate correlation between progression-free survival (PFS) or time to progression (TTP) and OS (R = 0.84 and R = 0.83, respectively). Nonetheless, the significant differences in PFS identified in 7 phase III studies only correlated with differences in OS in 3 cases. In these cases, the hazard ratio (HR) for PFS was ≤0.6. Thus, this threshold is herein proposed as a potential surrogate endpoint of OS in advanced HCC. Conversely, PFS with an HR between 0.6-0.7, despite significance, was not associated with better survival, and thus these magnitudes are considered uncertain surrogates. In the current review, we discuss the reasons for positive or negative phase III trials in advanced HCC, and the strengths and limitations of surrogate endpoints (PFS, TTP and objective response rate [ORR]) to predict survival.

Abstract
Liver cancer is one of the leading causes of cancer-related mortality around the world. Hepatocellular carcinoma (HCC) is the primary cancer of the liver, accounting for the majority of liver cancers. The risk factors associated with HCC include chronic infections with HBV and HCV, alcoholic liver disease, and nonalcoholic fatty liver disease. Additionally, male patients have higher risk for than females, and the risk increases with older age. Mortality rates for HCC parallel its increasing incidence rates. In this context, incidence rate for HCC shows geographic variations in different parts of the world and is heavily affected by regional differences in risk factor for liver disease. The highest incidence rates for HCC are observed in Asia and Africa, while Europe and North America have lower rates. In fact, HBV is still regarded as the leading cause of HCC globally, while HCV is the most common cause of HCC in the USA. Recently, it has been suggested that HCC cases related to nonalcoholic fatty liver disease is on the rise, while the proportion of HCC attributed to alcoholic liver disease remains stable.

Abstract
Health related quality of life (HRQOL) is increasingly recognized as an important clinical parameter and research endpoint in patients with hepatocellular carcinoma (HCC). HRQOL in HCC patients is multifaceted and affected by medical factor which encompasses HCC and its complications, oncological and palliative treatment for HCC, underlying liver disease, as well as the psychological, social or spiritual reaction to the disease. Many patients presented late with advanced disease and limited survival, plagued with multiple symptoms, rendering QOL a very important aspect in their general well being. Various instruments have been developed and validated to measure and report HRQOL in HCC patients, these included general HRQOL instruments, e.g., Short form (SF)-36, SF-12, EuroQoL-5D, World Health Organization Quality of Life Assessment 100 (WHOQOL-100), World Health Organization Quality of Life Assessment abbreviated version; general cancer HRQOL instruments, e.g., the European Organisation for Research and Treatment of Cancer (EORTC) QLQ-C30, Functional Assessment of Cancer Therapy (FACT)-General, Spitzer Quality of Life Index; and liver-cancer specific HRQOL instruments, e.g., EORTC QLQ-HCC18, FACT-Hepatobiliary (FACT-Hep), FACT-Hep Symptom Index, Trial Outcome Index. Important utilization of HRQOL in HCC patients included description of symptomatology and HRQOL of patients, treatment endpoint in clinical trial, prognostication of survival, benchmarking of palliative care service and health care valuation. In this review, difficulties regarding the use of HRQOL data in research and clinical practice, including choosing a suitable instrument, problems of missing data, data interpretation, analysis and presentation are examined. Potential solutions are also discussed.
