Do patients with haematological malignancies suffer financial burden? A cross-sectional study of patients seeking care through a publicly funded healthcare system.

BACKGROUND: It is increasingly appreciated that some patients with cancer will experience financial burden due to their disease but little is known specifically about patients with haematological malignancies. Therefore, this study aimed to measure financial toxicity experienced by patients with haematological malignancies in the context of a publicly funded health care system. METHOD: All current patients diagnosed with leukaemia, lymphoma or multiple myeloma, from two major metropolitan health services in Melbourne, Australia were invited to complete a survey capturing; patient demographics, employment status, income sources, financial coping and insurances, OOP expenses and self-reported financial toxicity using a validated measure. RESULTS: Of the 240 people approached, 113 (47 %) participated and most had leukaemia (62 %). Forty-seven (42 %) participants experienced some degree of financial toxicity using the Comprehensive Score for financial toxicity (COST) instrument. On multivariate linear regression, older age (>65 years, p = 0.007), higher monthly income (>$8000, p = 0.008), not having and being forced into unemployment or early retirement (p < 0.001) remained significantly associated with less financial toxicity. CONCLUSION: Financial toxicity is present in Australian haematology patients and those at higher risk may be patients of working age, those without private health insurance and patients that have been forced to retire early or have become unemployed due to their diagnosis.

Efficacy and cost of G-CSF derivatives for prophylaxis of febrile neutropenia in lymphoma and multiple myeloma patients underwent autologous hematopoietic stem cell transplantation.

OBJECTIVES: To compare the efficacies and costs between pegfilgrastim and filgrastim prophylaxis for FN post-ASCT for lymphoma and multiple myeloma patients. METHODS: 43 patients who received pegfilgrastim (6 mg) were compared to a retrospective cohort of 129 patients that had received filgrastim post-ASCT. Hematopoietic recovery time, FN incidence and treatment costs were assessed and compared. RESULTS: The mean time to absolute neutrophil count engraftment was 8.72 ± 2.38 days for the prospective pegfilgrastim group and 9.87 ± 3.13 days for the retrospective filgrastim group (P = 0.027). The incidence of FN was 18.60% and 50.39% in prospective pegfilgrastim and retrospective filgrastim groups, respectively (P = 0.000). The mean cost of filgrastim was $617.22 ± 37.87, compared with $525.78 for pegfilgrastim (P = 0.032). DISCUSSION: Convenience, effectiveness, and safety of prophylaxis for FN in the prospective pegfilgrastim group were significantly improved compared to the retrospective filgrastim group in ASCT patients. CONCLUSION: Pegfilgrastim prophylaxis was more effective and convenient than filgrastim for FN prophylaxis in patients post-ASCT, especially for MM patients.

Risk Factors for Cost-Related Delays to Medical Care Among Lymphoma Patients: A 22-Year Analysis of a Nationally Representative Sample.

BACKGROUND: An estimated 85,000 cases of lymphoma (Hodgkin and non-Hodgkin lymphoma) were diagnosed in the United States in 2020. Financial insecurity is known to negatively impact health outcomes. In 2021, as Americans continue to file for unemployment at rates far above pre-COVID-19 pandemic peak levels, there is a persistent need to address the economic burden of diagnoses and threat of financial stressors and its related conditions, which are already known to cause substantial economic burden. PATIENTS AND METHODS: Data were obtained from the National Health Interview Survey (NHIS), a cross-sectional survey conducted annually by the National Center for Health Statistics. Two questions were asked of patients to identify potential risk factors of financial insecurity regarding patients' ability to pay medical bills. NHIS respondents between the years 1997 and 2018 self-reporting a history of lymphoma diagnoses was included in the analysis. RESULTS: Among over 2 million respondents to the NHIS between 1997 and 2018, 1619 individuals reported a history of lymphoma; 9.95% reported delaying medical care due to cost within the previous 12 months; and 6.52% reported not being able to afford medical care in the previous 12 months. Among the subgroups that had the highest risk of delaying medical care were patients between the ages of 25 and 64 years and the uninsured. CONCLUSION: Financial burdens impede patients' abilities to access and adhere to care, which can contribute to poorer health outcomes. As financially insecure patients continue to present with lymphoma diagnoses, it is vital for practicing hematologists to understand the links among health care, financial insecurity, and demographic risk factors in order to devise and implement appropriate interventions.

Real-world costs of illness of Hodgkin and the main B-Cell Non-Hodgkin lymphomas in France.

Background: Lymphomas are costly diseases that suffer from a lack of detailed economic information, notably in a real-world setting. Decision-makers are increasing the search for Real-World Evidence (RWE) to assess the impact, in real-life, of healthcare management and to support their public decisions. Thus, we aimed to assess the real-world net costs of the active treatment phases of adult Hodgkin Lymphoma (HL), Follicular Lymphoma (FL) and Diffuse Large B Cell Lymphoma (DLBCL).Methods: We performed a retrospective cohort study using population-based data from a national representative sample of the French population covered by the health insurance system. Cost analysis was performed from the French health insurance perspective and took into account direct and sick leave compensation costs (€2,018). Healthcare costs were studied over the active treatment phase. We used multivariate modeling to adjust cost differences between lymphoma subtypes.Results: Analyses were performed on 224 lymphoma patients and 896 controls. The mean additional monthly costs due to HL, FL and DLBCL patients were respectively €5,188, €3,242 and €7,659 for the active treatment phase. The main additional cost driver was principally inpatient stay (hospitalization costs and costly cancer-related drugs), followed by outpatient medication and productivity loss. When adjusted, DLBCL remains significantly the most costly lymphoma subtype.Conclusion: This study provides an accurate assessment of the main lymphoma subtypes related cost with high magnitude of details in a real-world setting. We underline where potential cost saving could be realized via the use of biosimilar medication, and where lymphoma management could be improved with the early management of adverse events.KEY POINTSThis is one of the first studies which assess the additional cost of lymphoma in Europe, according the main sub-types of lymphoma and with real-world database.The additional monthly cost due to HL, FL and DLBCL patients were respectively €5,188, €3,242 and €7,659 for the active treatment phase and the main additional cost driver was principally inpatient stay (i.e. hospitalization costs and additional inpatient medicines, notably rituximab), followed by outpatient medication and productivity loss.This study provides an accurate and detailed lymphoma subtype cost description and comparison which supply data for efficiency evaluations and will allow French health policy to improve lymphoma management.

The economic impact of the transition from branded to generic oncology drugs.

Background: Economic evaluations are an integral component of many clinical trials. Costs used in those analyses are based on the prices of branded drugs when they first enter the market. The effect of genericization on the cost-effectiveness (ce) or cost-utility (cu) of an intervention is unknown because economic analyses are rarely updated using the costs of generic drugs. Methods: We re-examined the ce or cu of regimens previously evaluated in Canadian Cancer Trials Group (cctg) studies that included prospective economic evaluations and where genericization has occurred or is anticipated in Canada. We incorporated the new costs of generic drugs to characterize changes in ce or cu. We also determined acceptable cost levels of generic drugs that would make regimens reimbursable in a publicly funded health care system. Results: The four randomized controlled trials included (representing 1979 patients) were cctg br.10 (early lung cancer, adjuvant vinorelbine-cisplatin vs. observation, n = 172), cctg br.21 (metastatic lung cancer, erlotinib vs. placebo, n = 731), cctg co.17 (metastatic colon cancer, cetuximab vs. best supportive care, n = 557), and cctg ly.12 (relapsed or refractory lymphoma, gemcitabine-dexamethasone-cisplatin vs. cytarabine-dexamethasone-cisplatin, n = 619). Since the initial publication of those trials, the genericization of vinorelbine, erlotinib, cetuximab, and cisplatin has taken place or is expected in Canada. Costs of generics improved the ces and cus of treatment significantly. For example, genericization of erlotinib ($1460.25 per 30 days) resulted in an incremental cost-effectiveness ratio (icer) of $45,746 per life-year gained compared with $94,638 for branded erlotinib. Likewise, genericization of cetuximab ($275.80 per 100 mg) produced an icer of $261,126 per quality-adjusted life-year (qaly) gained compared with $299,613 for branded cetuximab. Decreases in the cost of generic cetuximab to $129.39 and $63.51 would further improve the icer to $150,000 and $100,000 per QALY respectively. Conclusions: Genericization of a costly oncology drug can modify the ce and cu of a regimen significantly. Failure to revisit economic analyses with the costs of generics could be a missed opportunity for funding bodies to optimize value-based allocation of health care resources. At current levels, the costs of generics might not be sufficiently low to sustain publicly funded health care systems.

Mobilization of Hematopoietic Progenitor Cells for Autologous Transplantation Using Pegfilgrastim and Plerixafor: Efficacy and Cost Implications.

Filgrastim (FIL) is the most common growth factor combined with plerixafor for autologous hematopoietic progenitor cell mobilization, but requires daily, multi-injection administration. We adopted a standardized mobilization regimen with pegfilgrastim (PEG) and upfront plerixafor, allowing for a single injection given the long half-life and slow elimination of PEG. Between 2015 and 2017, a total of 235 patients with lymphoma or plasma cell dyscrasias underwent mobilization with PEG 6 mg on day 1 and upfront plerixafor 24 mg on day 3, followed by apheresis on day 4 regardless of peripheral blood CD34+ cells. The median CD34+ cells/mm3 in peripheral blood on first day of collection was 48 and median collection yield was 7.27 × 106 CD34+ cells/kg (range, 0.32 to 39.6 × 106 CD34+ cells/kg) after a mean of 1.6 apheresis collections. Overall, 83% of patients achieved the mobilization target, and 95% reached the minimum necessary CD34+ cell yield to proceed with transplantation (2 × 106 CD34+ cells/kg). Because FIL is weight-based and dosed daily, the cost comparison with PEG is influenced by patient weight and number of apheresis sessions required. A cost simulation using actual patient data indicates that PEG is associated with lower cost than FIL for the majority of patients. Autologous hematopoietic progenitor cell mobilization with PEG and plerixafor is practical, effective, and not associated with increased cost compared with FIL mobilization.

Long-term effects of cancer on earnings of childhood, adolescent and young adult cancer survivors - a population-based study from British Columbia, Canada.

BACKGROUND: The patterns and determinants of long-term income among young people surviving cancer, and differences compared to peers, have not yet been fully explored. The objectives of this paper are to describe long-term income among young survivors of cancer, the impact of socio-demographic, disease, and treatment factors on long-term income, and income relative to the general population. METHODS: Retrospective cohort study with comparison group from the general population, using linked population-based registries, clinical data, and tax-records. Multivariate random effects regression models were used to determine survivor income, compare long-term income between survivors and comparators, and assess income determinants. Subjects included all residents of British Columbia (BC), Canada, diagnosed with cancer before 25 years of age and surviving 5 years or more. Comparators were selected from the BC general population matched by gender and birth year. RESULTS: Young cancer survivors earned significantly less than the general population. In addition, survivors of central nervous system tumors have significantly lower incomes than lymphoma survivors. Survivors who received radiation therapy have significantly lower income. Results should be interpreted with caution as the comparator group was matched by gender and date of birth. CONCLUSIONS: Depending on original diagnosis, treatment, and other characteristics, survivors face significantly lower income than peers and may require supports to gain and retain paid employment. Lower income will affect their opportunity for independent living, and will reduce productivity in the labour force.

Time to diagnosis and associated costs of an outpatient vs inpatient setting in the diagnosis of lymphoma: a retrospective study of a large cohort of major lymphoma subtypes in Spain.

BACKGROUND: Mainly because of the diversity of clinical presentations, diagnostic delays in lymphoma can be excessive. The time spent in primary care before referral to the specialist may be relatively short compared with the interval between hospital appointment and diagnosis. Although studies have examined the diagnostic intervals and referral patterns of patients with lymphoma, the time to diagnosis of outpatient compared to inpatient settings and the costs incurred are unknown. METHODS: We performed a retrospective study at two academic hospitals to evaluate the time to diagnosis and associated costs of hospital-based outpatient diagnostic clinics or conventional hospitalization in four representative lymphoma subtypes. The frequency, clinical and prognostic features of each lymphoma subtype and the activities of the two settings were analyzed. The costs incurred during the evaluation were compared by microcosting analysis. RESULTS: A total of 1779 patients diagnosed between 2006 and 2016 with classical Hodgkin, large B-cell, follicular, and mature nodal peripheral T-cell lymphomas were identified. Clinically aggressive subtypes including large B-cell and peripheral T-cell lymphomas were more commonly diagnosed in inpatients than in outpatients (39.1 vs 31.2% and 18.9 vs 13.5%, respectively). For each lymphoma subtype, inpatients were older and more likely than outpatients to have systemic symptoms, worse performance status, more advanced Ann Arbor stages, and high-risk prognostic scores. The admission time for diagnosis (i.e. from admission to excisional biopsy) of inpatients was significantly shorter than the time to diagnosis of outpatients (12.3 [3.3] vs 16.2 [2.7] days; P < .001). Microcosting revealed a mean cost of €4039.56 (513.02) per inpatient and of €1408.48 (197.32) per outpatient, or a difference of €2631.08 per patient. CONCLUSIONS: Although diagnosis of lymphoma was quicker with hospitalization, the outpatient approach seems to be cost-effective and not detrimental. Despite the considerable savings with the latter approach, there may be hospitalization-associated factors which may not be properly managed in an outpatient unit (e.g. aggressive lymphomas with severe symptoms) and the cost analysis did not account for this potentially added value. While outcomes were not analyzed in this study, the impact on patient outcome of an outpatient vs inpatient diagnostic setting may represent a challenging future research.

Barriers and facilitators to participation in clinical trial among lymphoma patients from Sun Yat-sen University Cancer Center in China: An observation study.

Recruitment rate of clinical trials in cancer patients is pretty low in China. Little is known about factors influencing trial recruitment in Chinese cancer patients. The aim of present study is to evaluate the barriers and facilitators to participation in clinical trials among lymphoma patients in China.From December 2014 to August 2015, the survey was carried out in the Department of Medical Oncology in Sun Yat-sen University Cancer Center. A self-made questionnaire was used among lymphoma patients (N = 331) to evaluate their attitude toward clinical trials. The questionnaire included 2 parts: patients' basic information and whether they were willing to participate in future clinical trials and their reasons.There were 53.5% patients willing to participate in clinical trials. The most common reasons were thirst for new treatments, trust on hospital and doctors, the idea that clinical trials may be more effective than conventional therapy, and to get more management and monitoring. The following patients are more likely to participate in clinical trials: patients who have children (P = .019) or spouse (P = .037), cannot afford treatment cost (P = .019), have tumor relapse (P = .045), and cared about the medical development (P = .032). Patients who have little knowledge of clinical trials are less likely to participate in clinical trials (P = .047).Popularization of knowledge about clinical trial is helpful to improve clinical trial participation in Chinese lymphoma patients.

Therapeutic Use of Filgrastim for Established Febrile Neutropenia Is Cost Effective Among Patients With Solid Tumors and Lymphomas.

PURPOSE: With the emergence of biosimilar filgrastim to the market, there is a gradual decrease in the listed price of the originator product of filgrastim over the years, and this could have an impact on the cost-effectiveness of filgrastim in the treatment of febrile neutropenia (FN). A cost-effectiveness analysis would allow clinicians to make informed decision when considering the therapeutic filgrastim among low-risk FN patients. This study aims to evaluate the cost-effectiveness of adding therapeutic filgrastim to antibiotics in the treatment of established FN among patients with solid tumors and lymphomas. METHODS: A decision tree model was created to compare two treatment options for established FN as follows: (1) antibiotics alone (standard care) and (2) antibiotics with therapeutic filgrastim (comparator). The target population was a hypothetical cohort of adult cancer patients with solid tumors or lymphomas hospitalized with FN in Singapore. The analysis was performed from a hospital's perspective over a 21-day time horizon. The main outcome measures included costs, quality-adjusted life year (QALY) and incremental cost-effectiveness ratio (ICER). One-way sensitivity analysis and probabilistic sensitivity analysis were conducted to evaluate the robustness of the results. FINDINGS: Compared with antibiotics alone, the treatment strategy of antibiotics with therapeutic filgrastim was a dominant choice, incurring a cost saving of US$125 per patient (comparator versus standard care: US$9110 versus US$9235) and additional health benefit of 0.0007 QALY gained per patient (comparator versus standard care: 0.0450 versus 0.0443). Model results were robust against the parameter variations in the one-way sensitivity analyses, but increasing the cost of filgrastim beyond US$87 per injection would increase the ICER to >US$50,000/QALY. Furthermore, the strategy of antibiotics with therapeutic filgrastim was the preferred choice (dominant or cost-effective) in 83.7% of the model iterations at a willingness-to-pay threshold of US$50,000/QALY. IMPLICATIONS: From a hospital's perspective, the therapeutic filgrastim, in conjunction with antibiotics, in the treatment of FN is cost effective. This provides evidence to support the routine use of filgrastim for the treatment of FN among adult cancer patients with solid tumors and lymphomas.

Costs for Childhood and Adolescent Cancer, 90 Days Prediagnosis and 1 Year Postdiagnosis: A Population-Based Study in Ontario, Canada.

BACKGROUND: Childhood and adolescent cancers are uncommon, but they have important economic and health impacts on patients, families, and health care systems. Few studies have measured the economic burden of care for childhood and adolescent cancers. OBJECTIVES: To estimate costs of cancer care in population-based cohorts of children and adolescents from the public payer perspective. METHODS: We identified patients with cancer, aged 91 days to 19 years, diagnosed from 1995 to 2009 using cancer registry data, and matched each to three noncancer controls. Using linked administrative health care records, we estimated total and net resource-specific costs (in 2012 Canadian dollars) during 90 days prediagnosis and 1 year postdiagnosis. RESULTS: Children (≤14 years old) numbered 4,396: 36% had leukemia, 21% central nervous system tumors, 10% lymphoma, and 33% other cancers. Adolescents (15-19 years old) numbered 2,329: 28.9% had lymphoma. Bone and soft tissue sarcoma, germ cell tumor, and thyroid carcinoma each comprised 12% to 13%. Mean net prediagnosis costs were $5,810 and $1,127 and mean net postdiagnosis costs were $136,413 and $62,326 for children and adolescents, respectively; the highest were for leukemia ($157,764 for children and $172,034 for adolescents). In both cohorts, costs were much higher for patients who died within 1 year of diagnosis. Inpatient hospitalization represented 69% to 74% of postdiagnosis costs. CONCLUSIONS: Treating children with cancer is costly, more costly than treating adolescents or adults. Substantial survival gains in children mean that treatment may still be very cost-effective. Comprehensive age-specific population-based cost estimates are essential to reliably assess the cost-effectiveness of cancer care for children and adolescents, and measure health system performance.

Factors and Costs Associated With Delay in Treatment Initiation and Prolonged Length of Stay With Inpatient EPOCH Chemotherapy in Patients With Hematologic Malignancies.

Reducing delays related to inpatient chemotherapy may reduce healthcare costs. Using a national database, we identified patients with lymphoma/leukemia with ≥1 etoposide, vincristine, doxorubicin, cyclophosphamide, and prednisone (EPOCH) chemotherapy claim and evaluated chemotherapy initiation delay (ID), >1 day from admission. Standard tests/procedures prior to initiation were evaluated. Among 4453 inpatient cycles, 19.7% had ID, odds ratio 2.28 (95% confidence interval: 1.83-2.85) with cycle 1 compared to cycle 2, and mean costs were higher in patients with ID than without ID (p < .0001). Prior to cycle 1, patients were more likely to undergo routine diagnostic procedures compared to subsequent cycles. Efforts to perform routine procedures prior to admission may reduce hospital length of stay and costs.

Real-World Conundrums and Biases in the Use of White Cell Growth Factors.

We present the 2015 American Society of Clinical Oncology (ASCO) white cell growth factors, or colony-stimulating factor (CSF), guidelines, updated from 2006. One new indication has been added-dose-intense chemotherapy for bladder cancer-to accompany the existing use for dose-dense breast cancer chemotherapy. Colony-stimulating factors remain appropriate for any regimen where the risk of febrile neutropenia is about 20% per cycle and dose reduction is not appropriate. Based on new evidence from multiple trials, CSF use is no longer indicated in treatment of lymphoma unless there are special risk factors. The United States accounts for 78% of the sales of CSF. The panel approved the use of all biosimilars, but the cost savings will be small as the price is about 80% of the branded CSFs. More biosimilars at lower cost are awaited. Methods to reduce use without harm to patients, by requiring justification according to accepted guidelines, are ongoing.

Evaluating the use of plerixafor in stem cell mobilisation - an economic analysis of the PHANTASTIC trial.

Plerixafor is an effective haematopoietic stem cell mobilising agent in candidates for autologous transplantation, including patients with myeloma and lymphoma. Here we compare 98 plerixafor recipients in the PHANTASTIC trial with 151 historic controls mobilised by conventional chemotherapy (each with granulocyte colony-stimulating factor, G-CSF). Seventy (71.4%) plerixafor-mobilised patients achieved the composite primary endpoint of ≥4 × 10(6) CD34+ cells kg(-1) in ≤2 aphereses and no clinically significant neutropenia, compared to 48 (31.8%) historic controls (P < 0.001), and this significant advantage was maintained in scenario analyses testing components of this composite endpoint. A patient-level cost analysis was undertaken for 249 patients, which included the cost of remobilising patients where initial mobilisation had failed. Combined mean treatment cost for plerixafor mobilised patients was £12,679 compared with £11,694 for historical controls. However, plerixafor produces an average saving of £3,828 per lymphoma patient but average cost increase by £5,245 per myeloma patient. The present data demonstrate cost-effectiveness for plerixafor as a first line mobilisation agent, certainly for lymphoma patients, where substantial resource savings and achievement of the primary endpoint are likely.

Gemcitabine/dexamethasone/cisplatin vs cytarabine/dexamethasone/cisplatin for relapsed or refractory aggressive-histology lymphoma: cost-utility analysis of NCIC CTG LY.12.

BACKGROUND: The NCIC CTG LY.12 study showed that gemcitabine, dexamethasone, and cisplatin (GDP) were noninferior to dexamethasone, cytarabine, and cisplatin (DHAP) in patients with relapsed or refractory aggressive histology lymphoma prior to autologous stem cell transplantation. We conducted an economic evaluation from the perspective of the Canadian public healthcare system based on trial data. METHODS: The primary outcome was an incremental cost utility analysis comparing costs and benefits associated with GDP vs DHAP. Resource utilization data were collected from 519 Canadian patients in the trial. Costs were presented in 2012 Canadian dollars and disaggregated to highlight the major cost drivers of care. Benefit was measured as quality-adjusted life-years (QALYs) based on utilities translated from prospectively collected quality-of-life data. All statistical tests were two-sided. RESULTS: The mean overall costs of treatment per patient in the GDP and DHAP arms were $19 961 (95% confidence interval (CI) = $17 286 to $24 565) and $34 425 (95% CI = $31 901 to $39 520), respectively, with an incremental difference in direct medical costs of $14 464 per patient in favor of GDP (P < .001). The predominant cost driver for both treatment arms was related to hospitalizations. The mean discounted quality-adjusted overall survival with GDP was 0.161 QALYs and 0.152 QALYs for DHAP (difference = 0.01 QALYs, P = .146). In probabilistic sensitivity analysis, GDP was associated with both cost savings and improved quality-adjusted outcomes compared with DHAP in 92.6% of cost-pair simulations. CONCLUSIONS: GDP was associated with both lower costs and similar quality-adjusted outcomes compared with DHAP in patients with relapsed or refractory lymphoma. Considering both costs and outcomes, GDP was the dominant therapy.

Productivity loss due to premature mortality caused by blood cancer: a study based on patients undergoing stem cell transplantation.

INTRODUCTION: Stem cell transplantation has been used for many years to treat haematological malignancies that could not be cured by other treatments. Despite this medical breakthrough, mortality rates remain high. Our purpose was to evaluate labour productivity losses associated with premature mortality due to blood cancer in recipients of stem cell transplantations. METHODS: We collected primary data from the clinical histories of blood cancer patients who had undergone stem cell transplantation between 2006 and 2011 in two Spanish hospitals. We carried out a descriptive analysis and calculated the years of potential life lost and years of potential productive life lost. Labour productivity losses due to premature mortality were estimated using the Human Capital method. An alternative approach, the Friction Cost method, was used as part of the sensitivity analysis. RESULTS: Our findings suggest that, in a population of 179 transplanted and deceased patients, males and people who die between the ages of 30 and 49 years generate higher labour productivity losses. The estimated loss amounts to over €31.4 million using the Human Capital method (€480,152 using the Friction Cost method), which means an average of €185,855 per death. The highest labour productivity losses are produced by leukaemia. However, lymphoma generates the highest loss per death. CONCLUSIONS: Further efforts are needed to reduce premature mortality in blood cancer patients undergoing transplantations and reduce economic losses.

Safety and efficacy of granulocyte colony-stimulating factor biosimilars in engraftment after autologous stem cell transplantation for haematological malignancies: a 4-year, single institute experience with different conditioning regimens.

BACKGROUND: Filgrastim biosimilars have recently been introduced into clinical practice. To date biosimilars have demonstrated comparable efficacy and safety as the originator in chemotherapy-induced neutropenia. Published experience in engraftment after autologous stem cell transplantation (ASCT) is limited and concerns relatively few patients. MATERIALS AND METHODS: With the aim of assessing the efficacy and the safety of filgrastim biosimilars in post-ASCT bone marrow recovery, we conducted a single institution, retrospective study in 56 lymphoma and myeloma patients who received filgrastim biosimilars (Tevagrastim(®) and Zarzio(®)) at standard doses from day 5. We compared our results with recently published data on the originator. A cost analysis of each biosimilar was performed. RESULTS: Neutrophil counts recovered in 55 patients. The median number of filgrastim biosimilar vials injected was seven per patient. The median time to neutrophil and platelet recovery was 10 and 12 days, respectively. Twenty-six patients had febrile neutropenia, in half of whom the agent involved was identified. In the cost analysis, the use of Tevagrastim(®) and Zarzio(®) was associated with cost reductions of 56% and of 86%, respectively. DISCUSSION: Despite differences in CD34+ cell counts and time of starting filgrastim, our results in terms of time to engraftment and median number of vials injected are similar to published data. Comparing our results by single conditioning regimen to recent literature data, the time to engraftment and duration of hospitalisation were equivalent. Significant differences were observed in the incidence of febrile neutropenia, perhaps due to different preventive and prophylactic protocols for infections. Although prospective studies should be performed to confirm our results, filgrastim biosimilars were found to be effective and safe in engraftment after ASCT.

Combined modality therapy versus chemotherapy alone as an induction regimen for primary central nervous system lymphoma: a cost-effectiveness analysis.

BACKGROUND: In immunocompetent patients with primary central nervous system lymphoma (PCNSL), combined modality therapy (CMT) using high-dose methotrexate and radiotherapy (WBRT) has improved response rates compared with chemotherapy alone. The trade-off is delayed and potentially devastating treatment-related neurotoxicity (NT). METHODS: A cost-effectiveness analysis using a Markov model compared CMT with chemotherapy alone in age-stratified patients with PCNSL. Baseline probabilities were derived from a systematic literature review. Direct and lost productivity costs were collected from a Canadian perspective and presented in Can$ in 2011. Outcomes were life expectancy, quality-adjusted life years (QALYs), and incremental cost-effectiveness ratio. RESULTS: The quality-adjusted life expectancy was 1.55 QALYs for CMT and 1.53 QALYs for chemotherapy alone. In younger patients (aged <60 years), CMT yielded 2.44 QALYs, compared with 1.89 QALYs for chemotherapy alone, yielding an expected benefit with CMT of 0.55 QALYs or 6.6 quality-adjusted months. The CMT strategy dominated in younger patients, as it was Can$11 951 less expensive than chemotherapy alone. The chemotherapy-alone strategy dominated in older patients, as it was Can$11 244 less expensive than CMT, and there was no difference in QALYs between the strategies. The model was robust in sensitivity analyses of key variables tested through the plausible ranges obtained from costing sources and published literature. CONCLUSION: The preferred induction strategy for younger patients with PCNSL appears to be CMT, which minimized cost while maximizing life expectancy and QALYs. This analysis confirms that the preferred strategy for older patients is chemotherapy alone.
