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

Health-related quality of life and its influencing factors in patients with primary cutaneous B-cell lymphomas: A multicentric study in 100 patients

BACKGROUND

Primary cutaneous B-cell lymphomas (CBCL) are a group of rare malignant skin diseases that represent approximately 20%-30% of all primary cutaneous lymphomas (PCL). Previous studies revealed impaired health-related quality of life (HRQoL) in patients diagnosed with primary cutaneous T-cell lymphoma (CTCL). Currently, only small-sized studies investigated HRQoL in CBCL patients and lacked detailed analysis of respective subtypes.

OBJECTIVES

This study aims to investigate HRQoL in CBCL patients to identify independent factors of HRQoL impairment in CBCL patients.

METHODS

One hundred CBCL patients were recruited from eight German PCL centres in this multicentric, cross-sectional study from 2021 to 2022. The patients completed the dermatologic HRQoL questionnaire Skindex-29 and an investigator-designed 'CBCL-Questionnaire' with additional questions on HRQoL and clinical characteristics.

RESULTS

The Skindex-29 revealed that HRQoL in CBCL patients is impaired on a mild to moderate level. The multiple regression analysis identified parameters like worries about dying, feeling prejudiced/discriminated and impairment of daily activities to be independently associated with impairment of HRQoL. Highest scores for HRQoL impairment were found in patients with primary cutaneous follicle centre lymphoma while on rituximab treatment and in patients with primary cutaneous marginal zone lymphoma while on watchful waiting.

CONCLUSIONS

HRQoL is impaired in CBCL patients, even though, in the face of indolent disease course and favourable prognosis in the majority of cases. Of note, our investigator-designed tool identified worries about dying, feeling prejudiced/discriminated, and the type of treatment to have a negative impact on patients' HRQoL. Our study highlights the importance of a thorough patient-doctor communication to capture overall disease burden because generic HRQoL tools might lack of disease-specific items.

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.

Cost-Effectiveness and Economic Burden Analyses on All First-Line Treatments of Chronic Lymphocytic Leukemia

OBJECTIVES

Several chemoimmunotherapy and targeted treatment regimens are approved as front-line therapies in chronic lymphocytic leukemia. We estimated for the 10-year cost-effectiveness of these treatment regimens and the economic burden of following the estimated risk-stratified 21 040 patients with chronic lymphocytic leukemia diagnosed in 2020 for 10 years.

METHODS

A Markov model with 7 exclusive health states was specified over a 10-year time horizon. Treatment effectiveness inputs were obtained from a novel network meta-analysis on the progression-free survival, overall survival curves, and time to next treatment. Costs and utilities inputs were included for each health state for each treatment and discounted at 3.0%/year. Life-years (LYs) and quality-adjusted LYs (QALYs) for each treatment were determined. Using the lowest cost regimen as reference, the incremental cost-effectiveness ratio (ICER) and incremental cost-utility ratio (ICUR) were estimated. The 10-year per-patient cost was determined by risk status and by initial treatment.

RESULTS

Venetoclax-plus-obinutuzumab was the lowest cost regimen, hence the reference. Superior in effectiveness to all chemoimmunotherapies, it was cost saving. With the highest effectiveness gains at 6.26 LYs and 5.01 QALYs and despite being the most expensive regimen ($1 298 638 per patient), acalabrutinib-plus-obinutuzumab yielded the best ICER ($409 343/LY gained) and ICUR ($501 236/QALY gained). The remaining ICERs of targeted therapies ranged from $512 101/LY gained to $793 236/LY gained and the ICURs from $579 737/QALY gained to $869 300/QALY gained. The 10-year postdiagnosis low/high (venetoclax-plus-obinutuzumab/acalabrutinib-plus-obinutuzumab) economic burden ranges were $42 690 to $98 665 for low-risk, $141 339 to $326 660 for intermediate-risk, and $273 650 to $632 453 for high-risk patients.

CONCLUSIONS

Compared with venetoclax-plus-obinutuzumab, chemoimmunotherapies are associated with less health benefits at higher cost. The targeted therapies achieve greater benefits at higher cost.

Factors Affecting Family Management Among Chinese Parents of Children With Leukemia: A Multisite Study

BACKGROUND

Effective family management can improve the ability of children's families to cope with the disease. However, the family management styles of children with leukemia are unknown.

OBJECTIVE

This study used a family management style framework and structural equation model to determine the direct and indirect predictors of family management of children with leukemia.

METHODS

A total of 496 parents of children with leukemia completed the Family Management Measure, the Feetham Family Functioning Survey, the Social Support Rating Scale, and a demographic family information form. We used structural equation modeling to explore the direct and indirect effects of the study variables on family management styles.

RESULTS

Family functioning, family income, parental education level, and geographic location affect family management directly, among which family functioning has the most significant coefficient in the model (0.53). Siblings and social support can affect family management through the mediating effect of family functioning. Employment change can directly affect family management (-0.27) and indirectly affect family functioning (-0.08).

CONCLUSIONS

Our results support the family management style framework. Individual and family factors such as family income, parental education level, geographic location, employment change, siblings, and social support contribute to the ease or difficulty of family management. In addition, family functioning can also mediate between contextual influences and family management styles.

IMPLICATIONS FOR PRACTICE

Family functioning plays a vital role in relationships between contextual influences and family management. We can construct family management interventions according to family management influencing factors.

Research on the Economics of Cancer-Related Health Care: An Overview of the Review Literature

We reviewed current literature reviews regarding economics of cancer-related health care to identify focus areas and gaps. We searched PubMed for systematic and other reviews with the Medical Subject Headings "neoplasms" and "economics" published between January 1, 2010, and April 1, 2020, identifying 164 reviews. Review characteristics were abstracted and described. The majority (70.7%) of reviews focused on cost-effectiveness or cost-utility analyses. Few reviews addressed other types of cancer health economic studies. More than two-thirds of the reviews examined cancer treatments, followed by screening (15.9%) and survivorship or end-of-life (13.4%). The plurality of reviews (28.7%) cut across cancer site, followed by breast (20.7%), colorectal (11.6%), and gynecologic (8.5%) cancers. Specific topics addressed cancer screening modalities, novel therapies, pain management, or exercise interventions during survivorship. The results indicate that reviews do not regularly cover other phases of care or topics including financial hardship, policy, and measurement and methods.

Unmet supportive care needs, anxiety and depression in haematology patients during watch-and-wait

OBJECTIVE

There is growing evidence and awareness of the psychological impact of watch-and-wait in patients with indolent haematological malignancy. However, the need for supportive care is unknown. The aims of this study were to investigate prevalence of unmet needs, their psychological associates, and prevalence of anxiety and depressive symptomatology.

METHODS

Adult patients with indolent haematological malignancy, during watch-and-wait (n = 122) were included in this cross-sectional single-centre study. Participants filled out questionnaires on anxiety (Generalised Anxiety Disorder), depression (Patient Health Questionnaire), coping (Acceptance and Action Questionnaire II), distress (distress thermometer), disease-specific quality of life (The European Organisation for Research and Treatment of Cancer quality of life questionnaire) and supportive care needs (Supportive care needs survey - Dutch short version). Multiple linear regression analyses were performed to identify patient-factors associated with unmet needs.

RESULTS

The prevalence of anxiety and depressive symptomatology were both 7.3%. Unmet needs were reported by 35% (n = 43) of patients. After controlling for covariates, higher levels of distress (β = 0.23, p = 0.05), depression (β = 0.41, p = 0.001), poorer coping (β = 0.35, p = 0.002) and younger age (β = -0.16, p = 0.05) were independently associated with more supportive care needs. The highest unmet needs were reported in domain health system, information & patient support (mean = 23.6 ± 23.0) and psychological domain (mean = 18.7 ± 21.8).

CONCLUSIONS

One third of indolent haematology patients during watch-and-wait report unmet supportive care needs. Screening for unmet needs and design of interventions is required. A joint approach focused on psychological care, especially on improving psychological flexibility, should be combined with promoting accessibility to health-services and optimising disease education.

Current and future treatment strategies in chronic lymphocytic leukemia

Treatment decisions for patients with chronic lymphocytic leukemia (CLL) are dependent on symptoms and classification into high-, medium-, or low-risk categories. The prognosis for CLL hinges, in part, on the presence or absence of less-favorable genetic aberrations, including del(17p), del(11q), TP53 dysfunction, and IGHV mutations, as these markers are associated with worse treatment response. Promising results from multiple clinical trials show emerging therapies targeting Burton tyrosine kinase, B-cell leukemia/lymphoma 2, and phosphatidylinositol 4,5-bisphosphate 3-kinase catalytic subunit delta result in better outcomes and prolonged progression-free survival for patients both with and without certain high-risk aberrations. Favorable outcomes using these novel oral targeted therapies, either alone or in combination with other treatments such as anti-CD20 antibodies, has led to their use almost entirely supplanting chemoimmunotherapy in the treatment of CLL. In this narrative review, we summarize the current clinical evidence for the use of targeted mono- and combination therapies for CLL, discuss new and next-generation treatment approaches currently in development, and provide insight into areas of unmet need for the treatment of patients with CLL.

Real-world healthcare resource utilization and costs in patients with chronic lymphocytic leukemia: differences between patients treated with first-line ibrutinib or bendamustine + rituximab

BACKGROUND

This study evaluated the real-world healthcare resource utilization and costs in chronic lymphocytic lymphoma (CLL) patients treated with first-line ibrutinib monotherapy (IbM) therapy or bendamustine plus rituximab (BR) combination therapy.

METHODS

Treatment-naïve CLL patients in the IBM MarketScan Research Databases were identified based on the first prescription of either IbM or BR therapy between 1 February 2014 and 30 August 2017.

RESULTS

A total of 1866 patients with 12 months of continuous enrollment (IbM n = 1157; BR=n = 729) were identified. Thirty-four percent of IbM patients had at least one inpatient admission compared to 24% of BR patients. A total of 31% of IbM patients had at least one CLL-related inpatient admission compared to 20% of BR patients. Among patients with an ER visit, IbM patients visited the emergency room (ER) more frequently than BR patients. There were no differences in total cost, both all-cause and CLL-related, between the IbM and BR cohorts. However, IbM patients had significantly higher all-cause and CLL-related inpatient costs than BR patients as well as all-cause outpatient pharmacy prescriptions costs, while BR patients had significantly higher PPPM outpatient medical costs.

CONCLUSION

The results of this study suggest that further research on the real-world effectiveness of IbM in comparison to BR combination therapy, given the comparatively higher rates of inpatient admissions, longer lengths of stay, and more ER visits observed in IbM patients relative to the BR patients is needed. Given the differences in costs, it is important to further examine the impact these healthcare expenditures have on the cost-effectiveness of IbM first line treatment.

Development of a Conceptual Model of Chronic Lymphocytic Leukemia to Better Understand the Patient Experience

BACKGROUND AND OBJECTIVE

Understanding the patient experience is important for identifying the unmet need in chronic lymphocytic leukemia. The current study aimed to develop a comprehensive chronic lymphocytic leukemia conceptual model.

METHODS

The conceptual model was based on literature searches, review of chronic lymphocytic leukemia patient blogs/forums, and interviews with five expert clinicians, with 20 patients who received at most one treatment (first line) for their chronic lymphocytic leukemia, and with 20 patients with relapsed or refractory chronic lymphocytic leukemia. De-identified interviews were transcribed, coded, and evaluated using qualitative data analysis software.

RESULTS

Thirty-five prevalent chronic lymphocytic leukemia-related symptom and impact concepts were identified from literature searches, patient blogs/forums, and clinician interviews. Patient interviews confirmed the identified concepts and revealed five additional concepts. Fatigue-related sub-components were identified from how patients described their fatigue, covering symptoms (tiredness/need for sleep, lack of energy, weakness, cognitive fatigue), and impacts (decreased ability to maintain their social, familial, or professional role, decreased physical functioning, frustration). Three versions of the conceptual model were created: an overall model with all concepts; a model highlighting the most prominent concepts in first line; and a model highlighting the most prominent concepts in relapsed or refractory disease. Prominent concepts in both first line and relapsed or refractory disease were fatigue-related symptoms and impacts, muscle/joint aches, night sweats, bruising, fever, recurrent infections/illness, insomnia, decreased cognitive/emotional functioning, anxiety/worry, stress, depression, financial difficulty, and fear of death. Dyspnea and cough were prominent in first line only, and enlarged lymph nodes, headaches, pain/discomfort, weight loss, nausea/vomiting, and infusion reactions were prominent in relapsed or refractory disease only.

CONCLUSIONS

The results show that fatigue is a dominant issue affecting patients with chronic lymphocytic leukemia. The three versions of the conceptual model can help researchers to understand patients' unmet needs and guide the patient-reported outcome strategy for clinical trials.

Healthcare resource utilization and costs associated with first-line ibrutinib compared to chemoimmunotherapy treatment among Medicare beneficiaries with chronic lymphocytic leukemia

OBJECTIVE

This retrospective observational study aimed to compare healthcare resource utilization and costs of Medicare beneficiaries with chronic lymphocytic leukemia (CLL)/small lymphocytic lymphoma (SLL) who received ibrutinib versus chemoimmunotherapy (CIT) in first line (1 L).

METHODS

Fee-for-service (FFS) and Medicare Advantage (MA) claims data were used to identify adults with a CLL/SLL diagnosis initiating 1 L ibrutinib single agent or CIT between 4 March 2016 and 30 September 2017 (index date). HRU and costs (Medicare spending) were evaluated during 1 L Oncology Care Model (1 L OCM) episodes (the first six months post-index) and over the observed 1 L duration. Patients' baseline characteristics were balanced using inverse probability of treatment weighting. Mean monthly cost differences (MMCDs) obtained from ordinary least square regressions were used to compare costs between ibrutinib and CIT cohorts.

RESULTS

In the Medicare FFS dataset (ibrutinib: n = 2014; CIT: n = 2050), ibrutinib patients incurred significantly higher monthly pharmacy costs (1 L OCM: MMCD = $4878, p < .0001; 1 L duration: MMCD= $4892, p < .0001) that were fully offset by lower monthly medical costs (1 L OCM: MMCD= -$8289, p < .0001; 1 L duration: MMCD=-$5888, p < .0001), yielding a monthly total healthcare cost reduction (1 L OCM: MMCD=-$3411, p < .0001; 1 L duration: MMCD=-$996, p < .0001) relative to CIT patients. In the MA dataset (ibrutinib: n = 293; CIT: n = 303), ibrutinib was also associated with a monthly total healthcare cost reduction (1 L OCM: MMCD=-$10,459; 1 L duration: MMCD=-$5492).

CONCLUSIONS

In Medicare patients with CLL/SLL, 1 L ibrutinib single agent was associated with total monthly cost savings relative to 1 L CIT, driven by lower monthly medical costs that fully offset higher monthly pharmacy costs.

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.

Budget Impact of 12-Month Fixed Treatment Duration Venetoclax in Combination with Obinutuzumab in Previously Untreated Chronic Lymphocytic Leukemia Patients in the United States

OBJECTIVES

This study aimed to assess the total cost of care (TCC) and budget impact of introducing 12-month fixed duration venetoclax + obinutuzumab (VEN+G) as first-line treatment for chronic lymphocytic leukemia (CLL) from the perspective of a US health plan with 1,000,000 (1M) members.

METHODS

The 3-year model included the following comparators: fludarabine + cyclophosphamide + rituximab (FCR), bendamustine + rituximab (BR), obinutuzumab + chlorambucil (GClb), ibrutinib (Ibr), and Ibr+Rituximab/obinutuzumab [Ibr+R/Ibr+G]). TCC included US-specific costs associated with treatment (i.e., drug, administration, and wastage), adverse events, routine care, and monitoring. Dosing and safety data were drawn from clinical trials and US package inserts. Budget impact outcomes were presented on an absolute and per-member per-month (PMPM) basis. Sensitivity analyses explored uncertainty in influential parameters, including scenarios testing the duration of treat-to-progression agents.

RESULTS

Over the 3-year time horizon, introducing VEN+G in a 1M-member health plan resulted in total cost savings of $1,550,663 (PMPM - $0.04), compared to a scenario without VEN+G. The fixed 12-month duration of VEN+G contributed to this cost saving by reducing cumulative treatment costs compared with Ibr-based regimens. By year 3, the cumulative difference in TCC of VEN+G compared with Ibr, Ibr+G, and Ibr+R amounted to - $300,942, - $367,001, and - $369,784, respectively. Extensive sensitivity analyses supported the base case findings.

CONCLUSIONS

Introducing VEN+G among first-line CLL treatments to a US health plan resulted in cost savings compared to a plan with chemoimmunotherapies and Ibr-based therapies only. Economic benefits of VEN+G, a novel agent with fixed treatment duration, coupled with proven clinical benefits should help inform formulary adoption decisions and treatment recommendations.

A Real-World Claims Analysis of Costs and Patterns of Care in Treated Patients with Glioblastoma Multiforme in the United States

BACKGROUND

Patients with glioblastoma multiforme (GBM) have a poor prognosis and high likelihood of recurrence. Routine care for incident cases in the United States involves surgical resection, followed by radiation therapy (RT) with concurrent and adjuvant temozolomide. Real-world data reporting the treatments and health care burden associated with GBM are limited.

OBJECTIVE

To assess patterns of care, health care resource utilization (HCRU), and costs associated with treatment of GBM in the United States.

METHODS

This study is a retrospective claims database analysis. Adult patients with a GBM diagnosis (index date) between January 1, 2010, and June 30, 2016, who had undergone brain surgery within 90 days of the index date, had received temozolomide and/or RT up to 90 days after index date, and had at least 6 months of continuous enrollment before the index date, were identified. Patients were excluded if they had (a) another primary cancer within 6 months pre-index, (b) secondary brain metastases, or (c) received temozolomide and/or RT pre-index. Baseline characteristics, treatments, HCRU, and costs were reported. First-line therapy began upon first receipt of RT and/or temozolomide after index date; second-line therapy began when a new drug was added > 28 days after initiation of first-line therapy or when there was a treatment gap > 90 days. Treatment regimens, duration of treatment (corrected group prognosis method), HCRU, and costs were reported descriptively in the 0- to 6-month and 7- to 12-month periods following initiation of first-line and second-line therapy.

RESULTS

Baseline characteristics were comparable between patients receiving temozolomide and/or RT. Patients receiving RT without chemotherapy tended to be older, be retired, and have more baseline comorbidities. Of the 4,071 patients receiving first-line therapy for GBM, most (73.0%) received temozolomide + RT; 24.4% received RT; and 2.5% received temozolomide monotherapy. Of those receiving first-line therapy, 1,283 (31.5%) patients subsequently received second-line therapy: 39.4% received bevacizumab monotherapy; 28.9% received bevacizumab combination therapy (temozolomide, 45.2% of patients; irinotecan, 24.3%; and temozolomide + lomustine, 15.4%); 15.5% received temozolomide monotherapy; and 13.7% received other systemic cancer therapies. The proportion of patients with hospitalizations increased from 2.9% (4-6 months pre-index) to 20.8% in the 3 months before the index date (likely due to diagnostic procedures) and 28.1% in the first 6 months after index (likely due to surgery) and then decreased to 13.3% in the 7- to 12-month period after index. Mean total per-patient costs at 6 and 12 months were $117,325 and $162,550 (first line) and $126,128 and $243,833 (second line). Costs in all time periods were largely driven by costs of RT/systemic cancer therapy.

CONCLUSIONS

Most patients with newly diagnosed GBM received treatment according to recommendations. However, relatively few patients received second-line therapy, and the HCRU burden and costs associated with both lines of therapy were substantial. Novel therapies for GBM are required to improve treatment options and outcomes in these patients.

Using Genomic Information to Guide Ibrutinib Treatment Decisions in Chronic Lymphocytic Leukaemia: A Cost-Effectiveness Analysis

BACKGROUND

Genomic tests may improve the stratification of patients to receive new therapies in several disease areas. However, the use of expensive targeted therapies can impact on the cost effectiveness of these tests. This study presents an economic evaluation of genomic testing in chronic lymphocytic leukaemia in the context of the UK National Health Service.

METHODS

Cost-effectiveness and cost-utility analyses (using life-years and quality-adjusted life-years) were undertaken from a National Health Service and societal perspective. Five strategies were evaluated across several age groups using Markov modelling: three strategies that reflected varying current genetic testing practice and two configurations of genomic testing (including ibrutinib treatment).

RESULTS

Genomic testing strategies yielded the most life-years/quality-adjusted life-years per patient, but were not cost effective compared with a threshold of £30,000 per life-year/quality-adjusted life-year gained. Cost-effectiveness acceptability curves indicated that there was some uncertainty surrounding this result. A genomic testing strategy becomes the most cost-effective option if a higher end-of-life cost-effectiveness threshold of £50,000 is applied, if a societal costing perspective is considered in 25-year-old patients or if the cost of ibrutinib treatment falls.

CONCLUSION

Stratifying patients with chronic lymphocytic leukaemia to targeted treatment using genomic testing improves health outcomes, but will likely only represent a cost-effective use of limited National Health Service resources if a higher cost-effectiveness threshold or societal costing perspective is applied, or if the price of ibrutinib treatment is reduced. This result may be broadly indicative of the likely cost effectiveness of other genomic tests that inform the stratification of patients to high cost-targeted therapies.

The potential combination of BCL-2 inhibitors and ibrutinib as frontline therapy in chronic lymphocytic leukemia

The recent development of small molecule inhibitors targeted at the B-cell receptor (BCR) pathway and the anti-apoptotic protein BCL-2 has revolutionized the care of patients with chronic lymphocytic leukemia (CLL). While durable responses to the BCR inhibitor ibrutinib have been observed in both previously untreated and relapsed/refractory CLL patients, residual disease is common in patients treated with single-agent ibrutinib. Interest remains high in therapeutic combinations that may lead to better quality remissions. A potential partner to ibrutinib with a distinct mechanism of action that is likely to lead to deeper responses is the BCL-2 inhibitor venetoclax. Preclinical studies have suggested synergism between inhibitors of BCR and BCL-2 and have paved the way to the development of ongoing clinical trials aimed at evaluating the combination of ibrutinib with venetoclax in CLL patients.

Economic evaluation of chronic lymphocytic leukemia from a hospital management perspective

OBJECTIVES

Treatment of chronic lymphocytic leukemia (CLL) is currently undergoing dramatic changes. We analyzed economic risks in hospitalized patients with CLL from a management perspective.

METHODS

One hundred and twelve patients with CLL hospitalized in 2013 and 2014 at the University Hospital of Cologne were analyzed. To assess profit margins (PMs) per case, diagnosis-related group (DRG) reimbursement data were merged with an internal cost accounting scheme depending on age, prognostic factors, and DRG key performance indicators.

RESULTS

In 112 patients, 284 cases coded by 19 different DRG with strongly fluctuating cost revenue ratios were found with an overall negative PM of €137 147. The DRG R61H was identified as the one most commonly coded (174 cases, 61.3%) with a deficit per case of €814. Subanalysis demonstrated that the payments were not cost covering due to excessive length of stay and staff costs. Significant differences in PM per case concerning age, length of stay and number of operation and procedure key (OPS) codes (P < 0.05) were found.

CONCLUSION

In our research-driven tertiary care hospital, inpatient treatment of patients with CLL is not cost covering. This analysis demonstrates the need for novel care/reimbursement structures in CLL. From a hospital management perspective, cost revenue controlling is crucial to avoid major economic risks.

The Effectiveness of Traditional Chinese Medicine in Treating Patients with Leukemia

Leukemia is the most common malignancy among all childhood cancers and is associated with a low survival rate in adult patients. Since 1995, the National Health Insurance (NHI) program in Taiwan has been offering insurance coverage for Traditional Chinese Medicine (TCM), along with conventional Western medicine (WM). This study analyzes the status of TCM utilization in Taiwan, in both pediatric and adult patients with leukemia. A retrospective cohort study was conducted using population-based National Health Insurance Research Database of Registry of Catastrophic Illness, involving patient data from 2001 to 2010 and follow-up data through 2011. The effectiveness of TCM use was evaluated. Relevant sociodemographic data showed that both pediatric and adult patients who were TCM users one year prior to leukemia diagnosis were more likely to utilize TCM services for cancer therapy. A greater part of medical expenditure of TCM users was lower than that of TCM nonusers, except little discrepancy in drug fee of adult patients. The survival rate is also higher in TCM users. Altogether, these data show that TCM has the potential to serve as an adjuvant therapy when combined with conventional WM in the treatment of patients with leukemia.
