RESUMO

BACKGROUND: A 2010 study on the impact of cancer mortality on productivity costs found Hodgkin lymphoma to have the second largest productivity cost lost per death in the United States. The ECHELON-1 trial demonstrated that frontline brentuximab vedotin, doxorubicin, vinblastine, and dacarbazine (A+AVD) improves overall survival (OS) vs doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD) in stage III/IV classical Hodgkin lymphoma (cHL), reducing the risk of death to 41% (hazard ratio = 0.59; 95% CI = 0.40-0.88; P = 0.009). OBJECTIVES: To assess the estimated impact of frontline treatment choice on mortality and productivity using an oncology simulation model informed by ECHELON-1 data. METHODS: Individual productivity was estimated using the human capital approach and reported via present value lifetime earnings (PVLE) estimates. Deaths avoided and lifeyears saved without and with A+AVD were calculated using a model informed by realworld treatment use, treatment-specific OS, and expert clinicians' opinions. A+AVD use in the base case was 27% (range: 0%-80%). Stage III/IV cHL prevalence over a 10-year period was estimated; downstream lifetime productivity costs were projected without and with A+AVD. RESULTS: In 2031, 3,645 patients were estimated to be newly diagnosed with stage III/IV cHL. Over 10 years with 27% A+AVD vs no A+AVD use, estimates predicted 14% fewer deaths (2,290 vs 2,650) and 14% less total PVLE losses ($1.438 vs $1.664 billion). Results from scenario analyses (40%-80% vs no A+AVD use) showed 20% to 32% decreases in PVLE losses ($1.331-$1.137 billion vs $1.664 billion), saving up to $527 million over 10 years. CONCLUSIONS: Productivity cost losses due to mortality in stage III/IV cHL are high. Increasing A+AVD use for patients with stage III/IV cHL would reduce productivity cost losses as deaths are avoided, based on ECHELON-1 OS results.

RESUMO

PURPOSE: This study aimed to systematically review and critically appraise cost-effectiveness studies on Brentuximab vedotin (BV) in patients with Hodgkin lymphoma (HL). METHODS: The PubMed, Scopus, Web of Science core collection, and Embase databases were searched until July 3, 2022. We included published full economic evaluation studies on BV for treating patients with HL. The methodological quality of the studies was assessed using the Quality of Health Economic Studies (QHES) checklist. Meanwhile, we used qualitative synthesis to analyze the findings. We converted the incremental cost-effectiveness ratios (ICERs) to the value of the US dollar in 2022. RESULTS: Eight economic evaluations met the study's inclusion criteria. The results of three studies that compared BV plus doxorubicin, vinblastine, and dacarbazine (BV + AVD) front-line therapy with doxorubicin, bleomycin, vincristine, and dacarbazine (ABVD) showed that BV is unlikely to be cost-effective as a front-line treatment in patients advanced stage (III or IV) HL. Four studies investigated the cost-effectiveness of BV in patients with relapsed or refractory (R/R) HL after autologous stem cell transplantation (ASCT). BV was not cost-effective in the reviewed studies at accepted thresholds. In addition, the adjusted ICERs ranged from $65,382 to $374,896 per quality-adjusted life-year (QALY). The key drivers of cost-effectiveness were medication costs, hazard ratio for BV, and utilities. CONCLUSION: Available economic evaluations show that using BV as front-line treatment or consolidation therapy is not cost-effective based on specific ICER thresholds for patients with HL or R/R HL. To decide on this orphan drug, we should consider other factors such as existence of alternative treatment options, clinical benefits, and disease burden.

RESUMO

BACKGROUND: The advent of targeted therapies and immunotherapies has revolutionized metastatic melanoma (MM) management but their use is associated with high daily costs compared to chemotherapies: €2 for dacarbazine versus €175 for immunotherapies and €413 for targeted therapies. While overall survival (OS) has increased, healthcare expenditures are expected to double by 2030. OBJECTIVES: The aim of this study was to estimate the median OS and costs for MM patients in order to evaluate the effectiveness of new biological or targeted therapies (NT) used since 2013 compared to chemotherapies. MATERIALS & METHODS: This was a retrospective monocentric cost-effectiveness analysis performed in CHU Nantes (Nantes University Hospital). All MM patients treated with conventional chemotherapy as first-line treatment between 2008 and 2012 were included (CHEMO group). The same number of patients treated with NT as first-line between 2013 and 2017 were included (NT group). RESULTS: In total, 161 patients were included in each group. The mean age at diagnosis was 64.7±2.4 years in the CHEMO group and 65.3±2.4 years in the NT group (not significant). The men/women ratio was 1.48 and 1.27, respectively, (not significant). The median OS was 158 days in the CHEMO group and 395 days in the NT group (p<0.001). Treatment cost was €10,280/patient versus €94,676/patient, respectively. The mean incremental cost-effectiveness ratio was €90,184/LY (95% CI: €59,637; €166,395). CONCLUSION: Our study assessed clinical and economic features associated with MM management before and after the advent of NT. Costs and life expectancy have increased. NT appears to be cost-effective.

RESUMO

INTRODUCTION: The InPOG-HL-15-01, a multicentric prospective study, used a risk-stratified and response-based approach with doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD) backbone to treat children and adolescents with newly diagnosed Hodgkin lymphoma (HL) and reduce the use of radiation therapy (RT). Children/adolescents with bulky disease or inadequate response at early response assessment (ERA) after two cycles of chemotherapy were assigned to receive RT. For ERA, positron emission tomography computed tomography (PET-CT) was recommended but not mandatory in view of limited access. This study aimed to compare the impact of using contrast-enhanced computed tomography (CECT) and PET-CT on treatment decisions and outcomes. METHODOLOGY: 396 patients were enrolled and 382 had an ERA at the assigned time point. Satisfactory response was defined as Deauville score 3 or less for patients undergoing PET-CT and complete response (CR)/very good partial response (VGPR) for patients undergoing CECT. Outcomes of interest incorporate 5 year event-free survival (EFS), EFS including abandonment (EFSa), and overall survival (OS). RESULTS: At ERA, satisfactory response was documented in 277 out of 382 (72.5%) participants and this was significantly higher in PET-CT (151 out of 186, 81.2%) as compared with CECT-based assessments (126 out of 196, 64.3%) respectively (p value < .001). Amongst the 203 patients with nonbulky disease (wherein the indication for RT was entirely dependent on ERA), 96 out of 114 (84.2%) and 61 out of 89 (68.5%) patients achieved a satisfactory response according to the PET-CT and CECT (p value = .008) respectively and hence a lesser proportion of patients in the PET-CT arm received RT. Despite a lower usage of RT the 5 year OS of both groups, ERA based on CECT (91.8%) versus PET-CT (94.1%) was comparable (p value = .391) and so was the 5 year EFS (86.7 vs. 85.5%, p value = .724). CONCLUSION: Use of PET-CT as the modality for ERA is more likely to indicate a satisfactory response as compared with CECT and thereby decreases the need for RT in response-based treatment algorithm for HL-afflicted children. The reduction in the application of RT did not impact the overall outcome and plausibly would lower the risk of delayed toxic effects.

RESUMO

INTRODUCTION: The standard of care for early-stage Hodgkin Lymphoma (HL) is combined modality therapy (CMT) consisting of chemotherapy and involved site radiation therapy (ISRT). Recent treatment de-escalation trials have assessed the impact of omitting radiation with the use of positron emission tomography (PET) and have suggested a detriment in progression free survival (PFS) for patients who do not receive radiation therapy (RT) but similar overall survival. The purpose of this study was to compare the cost-effectiveness of PET-directed therapy versus standard of care CMT. METHODS: This study used a cost-effectiveness Markov model simulating 5 year outcomes for 1 million patients with early-stage HL treated with either PET-directed therapy consisting of 2 cycles of ABVD chemotherapy ± ISRT or CMT consisting of 2 cycles of ABVD + ISRT. Patients progressed to no evidence of disease, progression of disease (PD), or death. Patients with PD underwent salvage therapy with high dose chemotherapy and stem cell transplant (HDC-SCT). The primary outcome measured was the incremental cost-effectiveness ratio. Deterministic sensitivity analyses were performed. RESULTS: We found that PET-directed therapy and CMT strategies were associated with costs of $47,362 and $41,167, respectively. The CMT strategy was equally as effective as the PET-directed therapy strategy with QALYs of 3.4. On 1-way sensitivity analyses, the model was most sensitive to CMT and HDC-SCT costs. Two-way sensitivity analyses showed the model was sensitive to the relative costs of these treatments. CONCLUSION: For patients with early-stage HL, CMT is the cost-effective strategy as compared with PET-directed therapy.

RESUMO

PURPOSE: Despite multiple randomized trials, variation in practice remains regarding the most effective treatment for early-stage, favorable-risk Hodgkin lymphoma. With increasing emphasis on alternative payment models, we investigate the cost-effectiveness of chemotherapy alone versus combined modality therapy (CMT). METHODS AND MATERIALS: A Markov model was formed to compared 2 cycles of adriamycin, bleomycin, vinblastine, and dacarbazine (ABVD) to 2 cycles of ABVD followed by 20 Gy in 10 fractions involved-site radiation therapy. Modalities were compared using the incremental cost-effectiveness ratio, with effectiveness measured in quality-adjusted life years (QALYs) and evaluated with a willingness to pay a threshold of $100,000 per QALY gained. RESULTS: The base case analysis showed that CMT is cost-effective compared with ABVD alone, with an incremental cost-effectiveness ratio of $8028 per QALY gained and an incremental cost of $236 gaining 0.029 QALYs. On sensitivity analyses, the results were the most sensitive to changes in recurrence rates. If the recurrence rate differences were ≥6%, CMT was cost-effective. CONCLUSIONS: CMT is a cost-effective strategy for early-stage, favorable-risk Hodgkin lymphoma based on currently available evidence. However, small variations in recurrence-rate estimates dramatically affect strategy cost-effectiveness.

RESUMO

INTRODUÇÃO: Embora não esteja entre os tumores malignos com maior incidência, o melanoma é considerado o tipo mais agressivo de câncer de pele devido ao grande potencial de disseminação à distância e consequente elevada letalidade. Em 2018, um total de 6.260 casos novos de melanoma maligno de pele foram estimados no Brasil, com aproximadamente 26% dos casos em estágio metastático e 1.794 óbitos registrados em 2015. O presente estudo avaliou as opções terapêuticas sistêmicas aprovadas pela Agência Nacional de Vigilância Sanitária (ANVISA) para o tratamento de primeira linha do melanoma avançado não cirúrgico e metastático. PERGUNTA: O uso de terapia-alvo ou imunoterapia é mais eficaz, seguro e custo-efetivo do que a quimioterapia com dacarbazina para o tratamento de primeira linha do melanoma avançado não-cirúrgico e metastático? TECNOLOGIAS: terapia-alvo (vemurafenibe, dabrafenibe, cobimetinibe, trametinibe) e imunoterapia (ipilimumabe, nivolumabe, pembrolizumabe). EVIDÊNCIAS CIENTÍFICAS: Quando comparadas ao tratamento padrão com dacarbazina, todas as terapias demonstraram superioridade estatisticamente significativa, tanto no desfecho de sobrevida livre de progressão (SLP) quanto em sobrevida global (SG), exceto dabrafenibe isolado. Em relação à SG, as estimativas pontuais demonstram maior benefício na redução do risco de morte com a combinação de nivolumabe/ipilimumabe (67%; 23% no pior cenário) seguida das imunoterapias isoladas com nivolumabe ou pembrolizumabe (54%; 41% no pior cenário), terapias-alvo combinadas (44-46%; 23-27% no pior cenário), imunoterapia isolada com ipilimumabe (32%; 7% no pior cenário) e terapia-alvo isolada com vemurafenibe (20%; 3% no pior cenário). Os eventos adversos graus 3/4 foram avaliados entre as classes terapêuticas de terapia-alvo, imunoterapia e quimioterapia. Os estudos reportaram menor risco de eventos adversos para a imunoterapia isolada anti-PD-1 (nivolumabe e pembrolizumabe) em relação à dacarbazina. As classes terapêuticas que apresentaram maior risco de eventos adversos foram: terapia-alvo isolada, terapia-alvo combinada, imunoterapia isolada com anti-CTLA-4 e imunoterapia combinada, todas com estimativa pontual de risco relativo acima de 1,40. AVALIAÇÃO ECONÔMICA: A avaliação de custo-efetividade demonstrou o ipilimumabe como a alternativa com menor razão de custo-efetividade incremental (ICER) em relação à dacarbazina. O nivolumabe e a sua associação com ipilimumabe tiveram melhores resultados em efetividade, porém com maior custo. Uma redução do preço do nivolumabe em 8 vezes tornaria seu ICER menor que 1 PIB per capita em relação à dacarbazina. A análise de sensibilidade probabilística revelou incertezas sobre a análise e o nivolumabe + ipilimumabe teve maior probabilidade que a dacarbazina de ser custo-efetivo em limiares próximos a R$322.000/QALY. AVALIAÇÃO DE IMPACTO ORÇAMENTÁRIO: O impacto orçamentário incremental em 5 anos variou de R$ 617.226.282,43 a R$ 2.880.924.401,13 para o ipilimumabe e sua associação com nivolumabe, respectivamente. As associações com terapia-alvo resultaram em impacto orçamentário menor que o nivolumabe, pois nessas estratégias apenas metade da população que tem a mutação BRAF seria tratada. O modelo buscou considerar além dos custos com os medicamentos, os custos diretos relacionados aos tratamentos. RECOMENDAÇÃO PRELIMINAR DA CONITEC: Os membros do Plenário da CONITEC presentes na 84ª reunião ordinária, no dia 05 de dezembro de 2019, definiram que o tema deve ser submetido à consulta pública com recomendação preliminar desfavorável à incorporação no SUS de terapia-alvo e da imunoterapia para o tratamento de primeira linha de pacientes com melanoma avançado não-cirúrgico e metastático. Apesar destas terapias apresentarem maior eficácia em relação à dacarbazina, o elevado custo do tratamento produziu uma relação de custo-efetividade e um impacto orçamentário incrementais que inviabilizam a sua incorporação. CONSULTA PÚBLICA: A Consulta Pública nº 85/2019, ocorreu entre os dias 02/01/2020 e 21/01/2020. Foram recebidas 2.300 contribuições, das quais 1.995 (mil novecentos e noventa e cinco) foram do formulário de experiência ou opinião e 305 (trezentos e cinco) do formulário técnico científico. Das contribuições de experiência ou opinião, 92% discordaram da recomendação preliminar e entre as contribuições técnico-científicas, 95% discordaram da recomendação preliminar e a maior parte das contribuições foram relacionadas à eficácia da terapia-alvo e da imunoterapia quando comparadas à dacarbazina. Os principais argumentos foram relacionados ao direito ao acesso ao tratamento de alto custo, eficácia dos tratamentos avaliados, e obsolescência do medicamento mais amplamente utilizado atualmente do SUS (dacarbazina). Foram recebidas contribuições de 4 (quatro) empresas fabricantes das tecnologias. Algumas contribuições levaram à atualização do modelo econômico, mas mostraram que o nivolumabe e a combinação nivolumabe com ipilimumabe permaneceram sendo as estratégias não dominadas. Outras terapias passaram a ter dominância extendida, mas não passaram a ser dominantes. Na discussão do tema, os membros do Plenário destacaram que a utilização do desfecho "cura dos pacientes com melanoma metastático", conforme apresentado pelo fabricante, não é adequado, por se tratar de uma avaliação indireta por meio de dados da literatura sobre respostas completas sustentadas em um período determinado de tempo. Foi ressaltado, em termos gerais, que as terapias avaliadas, principalmente imunoterapias anti-PD1, mudam inteiramente o contexto atual do melanoma metastático, representando uma evolução no tratamento. Porém, o custo das terapias permanece muito elevado. Houve novas propostas de preços pelas empresas fabricantes dos medicamentos anti-PD1 avaliados (nivolumabe e pembrolizumabe) que apresentaram satisfatórios perfis de eficácia e segurança. Com as informações adicionais a avaliação econômica foi atualizada com a alteração da duração de tratamento do pembrolizumabe e com novos preços propostos pelas empresas. Para o nivolumabe houve a proposta de redução do preço que era de R$27.882,36 para R$20.939,69, com duração de tratamento até a progressão da doença ou morte. Para o pembrolizumabe houve a proposta de redução do preço que era de R$28.954,80 para R$23.724 (ICMS 17%) ou R$19.690,02 (ICMS 0%), com duração de tratamento até progressão da doença ou morte ou até vinte e quatro meses em pacientes sem progressão. RECOMENDAÇÃO FINAL: Os membros da Conitec presentes na 88ª reunião ordinária, no dia 08 de julho de 2020, deliberaram, por unanimidade, por recomendar a incorporação no Sistema Único de Saúde da classe anti-PD1 (nivolumabe ou pembrolizumabe), para tratamento de primeira linha do melanoma avançado não cirúrgico e metastático, conforme modelo da assistência oncológica no SUS. Foram levadas em consideração as novas propostas de preços apresentadas pelas empresas fabricantes dos medicamentos anti-PD1 avaliados (nivolumabe e pembrolizumabe) além dos satisfatórios perfis de eficácia e segurança demonstrado pelos dois medicamentos. Discutiu-se que o custo mensal do tratamento de ambos os medicamentos deveriam ainda ser reduzidos conforme valor de referência de 3 PIB/per capita para uma razão de custo-efetividade incremental favorável. Foi discutida também a possibilidade de criação de um valor máximo para o procedimento na tabela SIGTAP com a recomendação da classe terapêutica. Foi assinado o Registro de Deliberação nº 533/2020. DECISÃO: incorporar a classe anti-PD1 (nivolumabe e pembrolizumabe) para o tratamento de primeira linha do melanoma avançado não-cirúrgico e metastático, conforme o modelo da assistência oncológica, no âmbito do Sistema Único de Saúde - SUS, conforme a Portaria nº 23, publicada no Diário Oficial da União nº 149, seção 1, página 91, em 05 de agosto de 2020.

RESUMO

The clinical management of older adult patients with Hodgkin lymphoma (HL) remains a major challenge. The aim of this study was to evaluate the impact of comorbidity assessment according to a standardized approach, the Cumulative Illness Rating Scale (CIRS), on prognosis in patients with classical HL aged 60 years and older. We studied 76 consecutive older adult patients with HL (median age 69 y, range 60-84) who had been treated in our institution between 1999 and 2018. Comorbidity was assessed at diagnosis according to CIRS. Anthracycline-containing chemotherapy with curative intent was administered in 59 (78%) patients. We identified 41 (54%) patients with at least one severe comorbidity rated on CIRS grade ≥ 3. Patients with severe comorbidity were more likely to have advanced-stage disease (P = .003), to have an International Prognostic Score (IPS) > 3 (P = .03), and to not receive anthracycline-containing chemotherapy (P = .008). The probability of overall survival (OS) at 3 years was 88% (95% CI, 71%-95%) in patients without severe comorbidities, while it was only 46% (95% CI, 29%-62%) in patients with a comorbidity CIRS grade ≥ 3 (P = .0001). The impact of comorbidity on prognosis was also evident when restricting the analysis to patients treated with anthracycline-containing therapy. The 3-year OS was 93% (95% CI, 76%-98%) (P = .004) in patients without severe comorbidity and 72% (95% CI, 47%-87%) in patients with severe comorbidity (P = .004). In a multivariate analysis, presence of comorbidity, but not age, was a significant factor for OS. Therefore, we conclude that a significant proportion of older adult patients with HL has severe comorbidity on the CIRS scale, which impacts more importantly than age on prognosis.

RESUMO

INTRODUCTION: In recent years, the positron emission tomography combined with computed tomography (PET/CT) has changed and the treatment approaches in Hodgkins lymphoma (HL) patients have entirely improved. The main idea in several studies is the use of PET/CT and the International Prognostic Score (IPS) protocols in identification of patients within a high-risk group and potential early relapse/refractory disease. MATERIALS AND METHODS: This study was based on PET/CT evaluation and treatment strategies of patients from eight Centers of Hematology in Ukraine. The patients included were newly dia-gnosed with HL and were aged 67 years or younger. They received a treatment with ABVD or BEACOPP-14/esc or “switched-regimens” (ABVD + BEACOPP-esc/14, BEACOPP-esc/14 + ABVD). The primary endpoints were to assess a correlation between PET/CT findings at the time of dia-gnosis, response to the therapy and clinical outcome (relapse/death) for patients with early and advanced stages of HL. The secondary endpoints were to evaluate the relationship between IPS and PET/CT findings. RESULTS: The study group included 106 patients. The overall response rate (ORR) was 90.5%. The ORR for patients with stages I-II was 96.5% (55/57) vs. 91% (41/45) for stage III-IV patients. In total, the disease progression occurred in 58.3% (7/12) of PET2+ patients and in 13.3% (12/90) of PET2 patients (P < 0.05). No significant difference was found between the event free survival (EFS) rate and IPS for patients with PET2+ vs. PET2, (log-rank test; P = 0.4). The PET3 status was found in 88.8% (79/89) of the study group patients and 1.2% (10/89) had a PET3+ status (P < 0.05). Using the Cox regression, we confirmed a significant correlation between EFS with PET3 Deauville scale (DS) and IPS. Patients with DS 1-2, DS 3 and DS 4-5 had a 1-year event-free survival of 94.4%, 100% and 33%, respectively (HR 0.56; 95% CI 1.07-2.8; P < 0.02). Our multivariable analysis showed no statistically significant correlation between PET2+ and PET3+ status and extranodal involvement or large tumor burden. CONCLUSION: The results of using PET/CT in patients with primary HL demonstrated a high prognostic value of PET at the end of the treatment. In addition, we confirmed the predictive role of IPS prognostic model in the treatment outcome depending on PET status.

RESUMO

Introduction: Outcomes of patients with classical Hodgkin lymphoma are excellent, and the intent of frontline therapy for even advanced-stage disease has been curative. This review summarizes the role of brentuximab vedotin in the upfront treatment of advanced stage classical Hodgkin lymphoma in the context of reducing therapy-related toxicity without compromising the high cure rate. Areas covered: Strategies to reduce bleomycin-induced lung toxicity include a response-adapted approach investigated in the RATHL study and a replacement of bleomycin with brentuximab vedotin in frontline chemotherapy regimens. In both studies, omission of bleomycin in the non-standard arms decreased the rate of pulmonary toxicity while maintaining high progression-free survival and overall survival rates. Expert opinion: The approval of A+AVD in North America offers a new bleomycin-free regimen for the treatment of advanced-stage HL, but it must be balanced against a risk-adapted approach. Recently presented subset analyses raise a question about which patients benefit most from this therapy.

RESUMO

PURPOSE: A novel value-based approach to evaluate costly specialty drugs for formulary addition was developed. SUMMARY: In February 2016, Stanford Health Care launched the specialty drug subcommittee (SDSC), a subcommittee of the pharmacy and therapeutics committee, responsible for the formulary review of specialty pharmaceuticals. A process was developed for value-based review that includes not only consideration of clinical trial data and institutional acquisition costs but also internal patient outcomes and a cost-effectiveness model using internal financial data. A Markov model was developed to assess the value of trabectedin, which was approved for formulary addition in April 2016, relative to the addition of dacarbazine. The economic model and internal patient outcome analysis were presented to the prescribing oncologist and the SDSC for review. Internal data revealed that fewer patients than had been estimated received trabectedin, with outcomes significantly worse than those observed in the clinical trial leading to Food and Drug Administration approval. In the cost-effectiveness model, trabectedin had higher costs and poorer outcomes compared with dacarbazine. Based on the economic model, low utilization, and real-world outcomes, trabectedin was removed from formulary and a restrictive treatment pathway for nonformulary use, developed by the primary prescriber, was implemented. This process has since been applied to 11 more specialty drugs. CONCLUSION: Internal cost-effectiveness models in combination with real-world patient outcomes data can be effective formulary management tools. Engagement and collaboration with the requesting provider are key to developing thoughtful treatment pathways.

RESUMO

OBJECTIVE: To estimate the incremental cost-utility ratio (ICUR) of isolated and combined targeted therapy regimens compared to dacarbazine for first-line treatment of advanced and metastatic melanoma with BRAF V600 mutation. METHODS: A Markov model with three health states (no progression, progression and death), monthly duration cycle and 10-year time horizon was constructed to compare targeted therapy regimens (vemurafenib, dabrafenib, vemurafenib/cobimetinib and dabrafenib/trametinib) with dacarbazine chemotherapy under the Brazilian public health perspective. One-way and probabilistic sensitivity analyses were performed. RESULTS: Mean cost was R$5662.50 ($1490.13) for dacarbazine, R$175 937.18 (46 299.26) for vemurafenib, R$167 461.70 ($44 068.87) for dabrafenib, R$425 901 ($112 079.21) for vemurafenib/cobimetinib and R$411 799.81 ($108 368.37) for dabrafenib/trametinib, whereas QALY was 0.91 for dacarbazine, 1.08 for vemurafenib, 1.12 for dabrafenib, 1.64 for vemurafenib/cobimetinib and 1.56 for dabrafenib/trametinib. The ICUR was estimated from R$572 165.76 ($150 569.94) to R$1 012 524.56 ($266 453.83) per patient, and the most impactful parameters were risk of progression and death, and treatment cost. CONCLUSION: The incorporation of targeted therapies in the Brazilian public health system would produce an additional expenditure of at least 19 times the national GDP per capita to increase in one year the quality-adjusted survival of each patient with advanced/metastatic BRAF-mutant melanoma.

RESUMO

PURPOSE: Drug wastage is a major concern in oncology where costs of antineoplastic drugs are exorbitant, and the disposal of toxic drugs increases the chances of occupational hazards to healthcare and sanitary workers and environmental pollution at the site of disposal. The principal objective of this study was to ascertain the extent of drug wastage and calculate its financial costs. MATERIALS AND METHODS: This was a prospective pilot study conducted to ascertain the quantity of drug wastage in a tertiary care hospital. This pilot study was conducted in day care and inpatient facilities in February 2016. The prescription of cytotoxic drugs, recommended dose, the quantity used, and remainder (waste) left were recorded from the nurses and pharmacy files of the hospital. Cost evaluation of the actual use and the waste was undertaken and an audit was conducted to understand in which anticancer drug the maximum wastage was generated. RESULTS: The results of this study indicated that 6.1% of the total amount of reconstituted drugs was wasted. The highest drug wastage was observed in trastuzumab (29.55%), followed by etoposide (20.4%), dacarbazine (17.14%), daunorubicin (16.67%), and carboplatin (11.29%). Cost analysis showed that the total cost of the drug issued during the study period was Rs. 1,294,975 and the cost of drug wastage amounted to Rs. 143,820 (11.1%). CONCLUSION: To the best of authors' knowledge, this is the first study from India and the results indicate that the financial impact of anticancer drug wastage was substantial. Attempts should be directed at minimizing the wastage and cost savings without risking patients' treatment regimen and administering effective dose schedule.

RESUMO

BACKGROUND: Immune-checkpoint inhibitors may provide long-term survival benefits via a cured proportion, yet data are usually insufficient to prove this upon submission to health technology assessment bodies. OBJECTIVE: We revisited the National Institute for Health and Care Excellence assessment of ipilimumab in melanoma (TA319). We used updated data from the pivotal trial to assess the accuracy of the extrapolation methods used and compared these to previously unused techniques to establish whether an alternative extrapolation may have provided more accurate survival projections. METHODS: We compared projections from the piecewise survival model used in TA319 and those produced by alternative models (fit to trial data with minimum follow-up of 3 years) to a longer-term data cut (5-year follow-up). We also compared projections to external data to help assess validity. Alternative approaches considered were parametric, spline-based, mixture, and mixture-cure models. RESULTS: Only the survival model used in TA319 and a mixture-cure model provided 5-year survival predictions close to those observed in the 5-year follow-up data set. Standard parametric, spline, and non-curative-mixture models substantially underestimated 5-year survival. Survival estimates from the TA319 model and the mixture-cure model diverge considerably after 5 years and remain unvalidated. CONCLUSIONS: In our case study, only models that incorporated an element of external information (through a cure fraction combined with background mortality rates or using registry data) provided accurate estimates of 5-year survival. Flexible models that were able to capture the complex hazard functions observed during the trial, but which did not incorporate external information, extrapolated poorly.

RESUMO

Objetivo: estimar o impacto orçamentário incremental da terapia-alvo para tratamento de primeira linha do melanoma avançado não cirúrgico e metastático, em comparação à dacarbazina. Métodos: análise de impacto orçamentário na perspectiva do Sistema Único de Saúde (SUS) do Brasil; a partir de dados demográficos e estimativas da incidência, foi delimitada a população no horizonte temporal de três anos (2018-2020) e estimados os custos diretos médicos; foi considerado cenário de referência o tratamento com dacarbazina, e como cenários alternativos a terapia-alvo com vemurafenibe, dabrafenibe, vemurafenibe + cobimetinibe e dabrafenibe + trametinibe; a avaliação das incertezas foi conduzida mediante análise por cenários. Resultados: o impacto orçamentário incremental variou de R$ 451.867.881,00 a R$ 768.860.968,00, representando 0,70 a 1,53% dos gastos anuais totais com medicamentos ambulatoriais no SUS; no melhor e no pior cenário, os resultados variaram de R$ 289.160.835,00 a R$ 1.107.081.926,00. Conclusão: a terapia-alvo, comparada à dacarbazina, implica impacto excessivo no orçamento, desfavorecendo eventual incorporação.

Objective: to estimate the incremental budget impact of target therapy for first-line treatment of advanced non-surgical and metastatic melanoma compared to dacarbazine treatment. Methods: budget impact analysis, from the Brazilian National Health System (SUS) perspective; based on demographic data and incidence estimates, the population over a three-year time horizon (2018-2020) was delimited and the direct medical costs were estimated; the reference scenario was treatment with dacarbazine, and the alternative scenarios were target therapy with vemurafenib, dabrafenib, vemurafenib + cobimetinib and dabrafenib + trametinib; uncertainty assessment was conducted through scenario analysis. Results: the incremental budget impact ranged from R$ 451,867,881.00 to R$ 768,860,968.00, representing 0.70 to 1.53% of total SUS annual outpatient drugs expenditure; in best and worst scenario, results ranged from R$ 289,160,835.00 to R$ 1,107,081,926.00. Conclusion: the use of target therapy compared to dacarbazine implies an excessive impact on the budget, this bring unfovorable to its possible incorporation.

RESUMO

PURPOSE: To evaluate whether imaging features of pathologic lymph nodes on whole-body diffusion-weighted MR have a predictive role before treatment and may assess the response after two courses of chemotherapy in comparison to FDG-PET/CT in Hodgkin Lymphoma. MATERIALS AND METHODS: We reviewed the whole-body MR and FDG-PET/CT performed on 41 patients with Hodgkin Lymphoma before and after two Doxorubicin-Bleomycin-Vinblastine-Dacarbazine (ABVD). Responder and non-responder lesions were identified on interim-FDG-PET/CT performed after two ABVD. We used Multivariate Generalized Estimating Equations model to assess statistical association between being-responder and baseline-Maximum Standard Uptake Value (SUVmax), baseline and interim-Apparent Diffusion Coefficient (ADC) and size, ADC and size changes during chemotherapy, site of disease, bulky, and stage. RESULTS: 10/41 (24%) patients were positive on interim-FDG-PET/CT. The interim-FDG-PET/CT positivity was associated with worse cumulative survival rate at 24 months in comparison to interim-FDG-PET/CT negativity (P < .05); 3/10 patients with positive interim-FDG-PET/CT and 1/31 with negative interim-FDG-PET/CT experienced disease progression. Baseline-SUVmax was 11.18 ±â€¯5.58 (3.1-28.0) and baseline-ADC was 0.70 ±â€¯0.14 × 10-3 mm2/s (0.39-0.98). There was a significant difference between responder and non-responder lesions based on interim-ADC (1.83 ±â€¯0.34 × 10-3 mm2/s vs. 1.01 ±â€¯0.27 × 10-3 mm2/s;p <.001), interim-size (3.1 cm2 vs. 9.4 cm2;p = .009), and bulky (8.2% vs. 66.7%;p = .002). There was no significant difference between responder and non-responder lesions based on baseline-SUVmax (p = .713), baseline-ADC (p = .253), ADC changes (p = .058), size changes (p = .085), site (p = .209), stage (p = .290), baseline-size (p = .064). CONCLUSIONS: Interim-ADC is helpful for identifying non-responder lesions, while size changes are not useful. Baseline-SUVmax and ADC have no predictive role. Bulky is the most useful imaging parameter to predict suboptimal response to chemotherapy.

RESUMO

BACKGROUND: Nivolumab was the first programmed death receptor 1 (PD-1) immune checkpoint inhibitor to demonstrate long-term survival benefit in a clinical trial setting for advanced melanoma patients. OBJECTIVE: To evaluate the cost effectiveness of nivolumab monotherapy for the treatment of advanced melanoma patients in England. METHODS: A Markov state-transition model was developed to estimate the lifetime costs and benefits of nivolumab versus ipilimumab and dacarbazine for BRAF mutation-negative patients and versus ipilimumab, dabrafenib, and vemurafenib for BRAF mutation-positive patients. Covariate-adjusted parametric curves for time to progression, pre-progression survival, and post-progression survival were fitted based on patient-level data from two trials and long-term ipilimumab survival data. Indirect treatment comparisons between nivolumab, ipilimumab, and dacarbazine were informed by these covariate-adjusted parametric curves, controlling for differences in patient characteristics. Kaplan-Meier data from the literature were digitised and used to fit progression-free and overall survival curves for dabrafenib and vemurafenib. Patient utilities and resource use data were based on trial data or the literature. Patients are assumed to receive nivolumab until there is no further clinical benefit, assumed to be the first of progressive disease, unacceptable toxicity, or 2 years of treatment. RESULTS: Nivolumab is the most cost-effective treatment option in BRAF mutation-negative and mutation-positive patients, with incremental cost-effectiveness ratios of £24,483 and £17,362 per quality-adjusted life year, respectively. The model results are most sensitive to assumptions regarding treatment duration for nivolumab and the parameters of the fitted parametric survival curves. CONCLUSIONS: Nivolumab is a cost-effective treatment for advanced melanoma patients in England.

RESUMO

OBJECTIVE: To assess the efficacy and cost-effectiveness of modulated electrohyperthermia (mEHT) concurrent to dose-dense temozolomide (ddTMZ) 21/28 days regimen versus ddTMZ 21/28 days alone in patients with recurrent glioblastoma (GBM). DESIGN: A cohort of 54 patients with recurrent GBM treated with ddTMZ+mEHT in 2000-2005 was systematically retrospectively compared with five pooled ddTMZ 21/28 days cohorts (114 patients) enrolled in 2008-2013. RESULTS: The ddTMZ+mEHT cohort had a not significantly improved mean survival time (mST) versus the comparator (p=0.531) after a significantly less mean number of cycles (1.56 vs 3.98, p<0.001). Effect-to-treatment analysis (ETA) suggests that mEHT significantly enhances the efficacy of the ddTMZ 21/28 days regimen (p=0.011), with significantly less toxicity (no grade III-IV toxicity vs 45%-92%, p<0.0001). An estimated maximal attainable median survival time is 10.10 months (9.10-11.10). Cost-effectiveness analysis suggests that, unlike ddTMZ 21/28 days alone, ddTMZ+mEHT is cost-effective versus the applicable cost-effectiveness thresholds €US$25 000-50 000/quality-adjusted life year (QALY). Budget impact analysis suggests a significant saving of €8 577 947/$11 201 761 with 29.1-38.5 QALY gained per 1000 patients per year. Cost-benefit analysis suggests that mEHT is profitable and will generate revenues between €3 124 574 and $6 458 400, with a total economic effect (saving+revenues) of €5 700 034 to $8 237 432 per mEHT device over an 8-year period. CONCLUSIONS: Our ETA suggests that mEHT significantly improves survival of patients receiving the ddTMZ 21/28 days regimen. Economic evaluation suggests that ddTMZ+mEHT is cost-effective, budget-saving and profitable. After confirmation of the results, mEHT could be recommended for the treatment of recurrent GBM as a cost-effective enhancer of ddTMZ regimens, and, probably, of the regular 5/28 days regimen. mEHT is applicable also as a single treatment if chemotherapy is impossible, and as a salvage treatment after the failure of chemotherapy.

RESUMO

BACKGROUND: Elderly glioblastoma (GB) patients are at risk of hospitalizations due to the morbidity of the disease and possible treatment toxicity. METHODS: In this observational cohort study, 255 newly diagnosed GB patients age 65 years and older were included. Survival, emergency room visits and admissions to an acute care hospital were determined. Mean and median total health care costs were calculated. Risk factors for Emergency room visits and acute care hospital admissions were determined. RESULTS: Median overall survival was 6 months. The majority of patients (68%) had at least one visit to the emergency department and 77% had at least one admission to acute care. The mean and median total costs (hospital, ambulatory, physician billing, other health care costs) per patient were $162,479.78 (CAN) and $125,511.00 (CAN), respectively. Treatment with radiation or treatment with radio-chemotherapy was associated with a relative risk (RR) of 2.31 (95% CI: 1.44-3.7; P=0.0005) and 2.19 (95% CI: 1.28-3.74; P=0.004), respectively for emergency department visits as compared to patients who were managed with comfort measures only. Patients with a baseline ECOG 0 had a RR of 1.71 (95% CI: 1.06-2.77; P=0.0289) and patients with baseline ECOG 1 had a RR of 1.49 (0.98-2.26; P=0.0623) for hospital admission as compared to patients with ECOG 4. CONCLUSIONS: A large proportion of elderly GB patients (particularly those with good baseline performance status who underwent active treatment) presented to the emergency department and had at least one admission to acute care.
