ABSTRACT

OBJECTIVE: The aim of this study is to evaluate the efficacy and cost-effectiveness of various induction chemotherapy (IC) regimens as first-line treatment for Locoregionally advanced nasopharyngeal carcinoma (LA-NPC), aiming to provide clinicians and patients with informed insights to aid in treatment decision-making. PATIENTS AND METHODS: We conducted a network meta-analysis (NMA) and cost-effectiveness analysis (CEA) based on data from 10 clinical trials investigating IC regimens for the treatment of LA-NPC. A Bayesian NMA was performed, with the primary outcomes being hazard ratios (HRs) for disease-free survival (DFS) and overall survival (OS). To model the disease progression of LA-NPC, we developed a dynamic partitioned survival model consisting of three disease states: progression-free survival (PFS), progression disease (PD), and death. The model was run on a 3-week cycle for a research period of 10 years, with quality-adjusted life-years (QALYs) and incremental cost-effectiveness ratios (ICERs) serving as outcome measures. RESULTS: According to the surface under the cumulative ranking curve (SUCRA) estimates derived from the NMA, TPC and TP, as IC regimens, appear to exhibit superior efficacy compared to other treatment modalities. In terms of CEA, concurrent chemoradiotherapy (CCRT), TPF + CCRT, and GP + CCRT were found to be dominated (more costs and less QALYs). Comparatively, TPC + CCRT emerged as a cost-effective option with an ICER of $1260.57/QALY when compared to PF + CCRT. However, TP + CCRT demonstrated even greater cost-effectiveness than TPC + CCRT, with an associated increase in costs of $3300.83 and an increment of 0.1578 QALYs per patient compared to TPC + CCRT, resulting in an ICER of $20917.62/QALY. CONCLUSION: Based on considerations of efficacy and cost-effectiveness, the TP + CCRT treatment regimen may emerge as the most favorable first-line therapeutic approach for patients with LA-NPC.

ABSTRACT

BACKGROUND: Hyperglycemia is a complication of induction chemotherapy in 10%-50% of pediatric patients with acute lymphoblastic leukemia (ALL). Though hyperglycemia in ALL patients is usually transient, it may be associated with adverse health outcomes. However, the risk factors for and consequences of hyperglycemia are poorly understood. We hypothesized that hyperglycemia significant enough to require insulin therapy during induction chemotherapy would be associated with increased morbidity and mortality in pediatric ALL patients during induction chemotherapy and in subsequent care. METHODS: We abstracted clinical and resource utilization data from the Pediatric Health Information System (PHIS) database utilizing ICD-9 codes and medication charges. We used logistic regression analysis to predict the development of hyperglycemia. The effects of hyperglycemia on binary and count adverse outcomes following induction chemotherapy were modeled using mixed-effect regression models. RESULTS: An increased risk of hyperglycemia requiring insulin was associated with older age, female sex, higher risk group and trisomy 21. Patients on insulin for hyperglycemia had increased mortality following induction chemotherapy. These patients were more likely to have subsequent infectious complications, need for bone marrow transplant, and risk of disease relapse. They also had greater length of inpatient stay, higher cost of care, and were more likely to require intensive care unit admission during induction chemotherapy. CONCLUSIONS: Hyperglycemia requiring insulin during induction chemotherapy in pediatric ALL is associated with an increased risk of short-term and long-term complications. Prospective studies are needed to analyze formal screening, preventive measures, and optimal management practices for hyperglycemia during ALL induction chemotherapy.

ABSTRACT

Aims: Acute myeloid leukemia (AML) treatment typically involves remission induction chemotherapy followed by consolidation chemotherapy. New treatments for AML have recently been introduced, including a chemotherapy formulation called CPX-351, which is administered via less time-intensive IV infusion than the standard "7 + 3" continuous infusion regimen of cytarabine plus an anthracycline. The purpose of this study was to estimate utilities that could be used in economic modeling of AML treatment. Materials and methods: In time trade-off interviews, participants from the UK general population valued 12 health states drafted based on literature and clinician interviews. To identify disutility associated with chemotherapy, two types of induction and four types of consolidation were added to an otherwise identical health state describing AML. The decrease in utility when adding these chemotherapy regimens represents the disutility of each regimen. Five additional health states were valued to estimate utilities associated with other AML treatments. Results: Two hundred participants completed interviews. Mean (SD) utilities were 0.55 (0.31) for pre-treatment AML and 0.66 (0.29) for AML in temporary remission. Adding any chemotherapy significantly decreased utility (p < 0.0001). Induction had a mean disutility of -0.11 with CPX-351 and -0.15 with 7 + 3. Mean disutility for consolidation ranged from -0.03 with outpatient CPX-351 to -0.11 with inpatient 5 + 2. Utilities are also reported for other AML treatments (e.g. transplant, low-intensity chemotherapy). Limitations: One limitation is that the differences in adverse event profiles between the treatment regimens were based on clinician opinion. Future use of CPX-351 in clinical trials or clinical settings will provide additional information on its adverse event profile. Conclusions: While all chemotherapy regimens were associated with disutility, regimens with shorter hospitalization and less time-intensive infusion were generally perceived as preferable. These utilities may be useful in cost-utility models comparing the value of AML treatments.

ABSTRACT

OBJECTIVE: To describe the setting, duration, and costs of induction and consolidation chemotherapy for adults with newly-diagnosed acute myeloid leukemia (AML), who are candidates for standard induction chemotherapy, in the US. METHODS: Adults newly-diagnosed with AML who received standard induction chemotherapy in an inpatient setting were identified from the Truven Health Analytics MarketScan (2006-2015) and SEER-Medicare (2007-2011) databases. Patients were observed from induction therapy start to the first of hematopoietic stem cell transplant, 180 days after induction discharge, health plan enrollment/data availability end, or death. Induction and consolidation chemotherapy were identified using Diagnosis-Related Group codes (chemotherapy with acute leukemia) or procedure codes for AML chemotherapy administration. AML treatment episode setting (inpatient or outpatient), duration, and costs (2015 USD, payers' perspective) were described for commercially insured patients and Medicare beneficiaries. RESULTS: In total, 459 commercially insured patients and 563 Medicare beneficiaries (mean age = 54 and 66 years; 53% and 54% male; respectively) were identified. For induction therapy, mean costs were $145,189 for commercially insured patients and $85,734 for Medicare beneficiaries, and median inpatient duration was 31 days (both). Following induction, 64% of commercially insured patients and 53% of Medicare beneficiaries had ≥1 consolidation cycle; 75% and 65% of consolidation cycles were in an inpatient setting, respectively. For consolidation cycles, in the inpatient setting, mean costs were $28,137 for commercially insured patients and $28,843 for Medicare beneficiaries, median cycle duration was 6 days (both); in the outpatient setting, mean costs were $11,271 for commercially insured patients and $5,803 Medicare beneficiaries, median duration was 5 days (both). LIMITATIONS: Granular information on chemotherapy type administered was unavailable. CONCLUSIONS: This is the first exploratory study providing a complete picture of recent AML treatment patterns and management costs among commercially insured patients and Medicare beneficiaries. There is substantial heterogeneity in the management and costs of AML.

ABSTRACT

The 5-year overall survival (OS) in patients ≥ 60 years old with acute myeloid leukemia (AML) remains < 10%. Clofarabine-based induction (CLO) provides an alternative to low-intensity therapy (LIT) and palliative care for this population, but supporting data are conflicted. Recently, our institution adopted the FLAG regimen (fludarabine, cytarabine, and granulocyte colony-stimulating factor) based on data reporting similar outcomes to CLO in elderly patients with AML unable to tolerate anthracycline-based induction. We retrospectively analyzed the efficacy and safety of patients ≥ 60 years old with AML treated with FLAG or CLO over the past 10 years. We performed a propensity score match that provided 32 patients in each group. Patients treated with FLAG had a higher CR/CRi rate (65.6 vs. 37.5%, P = 0.045) and OS (7.9 vs. 2.8 months, P = 0.085) compared to CLO. Furthermore, FLAG was better tolerated with significantly less grade 3/4 toxicities and a shorter duration of neutropenia (18.5 vs. 30 days, P = 0.002). Finally, we performed a cost analysis that estimated savings to be $30,000-45,000 per induction with FLAG. Our study supports the use of FLAG both financially and as an effective, well-tolerated high-dose treatment regimen for elderly patients with AML. No cases of cerebellar neurotoxicity occurred.

ABSTRACT

BACKGROUND AND AIMS: The optimal duration of dose-intensified therapy following secondary loss of response [LOR] to anti-tumour necrosis factor [TNF] therapy remains unclear. Anti-TNF re-induction involves a finite period of intensified therapy and may be a cost-effective means of re-capturing response. This study aimed to compare the efficacy, durability, and cost of anti-TNF re-induction and dose interval shortening [DIS] for secondary LOR in Crohn's disease [CD]. METHODS: This was a retrospective observational study in CD patients who developed secondary LOR to maintenance anti-TNF therapy, requiring subsequent re-induction and/or DIS. The primary outcome was treatment failure within 12 months. Secondary outcomes included factors associated with time to failure, disease activity, and incremental anti-TNF costs. RESULTS: Of 423 patients with CD on anti-TNF therapy, 80 [19%] developed secondary LOR, with 33 and 55 patients undergoing subsequent anti-TNF re-induction and DIS, respectively. There was no significant difference in the incidence of treatment failure at 12 months following re-induction and DIS, respectively [p = 0.27]. Factors predictive of a longer time to failure included a higher baseline serum albumin, male sex, and thiopurine co-therapy [each p < 0.05], whereas higher baseline faecal calprotectin was associated with shorter time to failure. There was no significant difference in clinical remission or objective disease activity across both groups. The median incremental cost of re-induction and DIS was AUD 4 838 and AUD 13 190, respectively. CONCLUSIONS: In patients with CD who develop secondary LOR, re-induction may represent an effective and less expensive first-line strategy, reserving dose intensification strategies such as DIS for non-responders.

ABSTRACT

BACKGROUND: The BEYOND trial found that the addition of bevacizumab (B) to paclitaxel-carboplatin (PC) chemotherapy provided a significant clinical benefit to Chinese patients with metastatic non-squamous non-small-cell lung cancer (NSCLC). This study aimed to evaluate the cost-effectiveness of adding B to first-line PC induction and continuation maintenance therapy from a Chinese perspective. METHODS: A Markov model was developed to estimate the cost and effectiveness of B + PC in the induction and maintenance therapy of patients with metastatic non-squamous NSCLC. Costs were calculated in the Chinese setting, and health outcomes derived from the BEYOND trial were measured as quality-adjusted life years (QALYs). A one-way sensitivity analysis was conducted to explore the impact of various parameters in the study. RESULTS: The B + PC treatment was more costly ($112,943.40 versus $32,171.43) and more effective (1.07 QALYs versus 0.80 QALYs) compared with the PC treatment. Adding B to the PC regimen for non-squamous NSCLC results in an incremental cost-effectiveness ratio of $299,155.44 per QALY, which exceeded the accepted societal willingness-to-pay threshold ($23,970.00) for China. In the sensitivity analysis, the duration of progression-free survival (PFS) for the B + PC group, the cost of the PFS state for B + PC group and the price of B were considered the most sensitive factors in the model. CONCLUSIONS: The addition of B to first-line PC induction and maintenance therapy was not determined to be a cost-effective strategy for metastatic non-squamous NSCLC in China, even when an assistance program was provided.

ABSTRACT

A health economic analysis was undertaken based on the 1-year database from a randomized study of rabbit anti-human thymocyte immunoglobulin (rATG) versus basiliximab, in kidney transplantation using resource utilization data and cost estimates from three German hospitals. A three-state Markov model was applied to estimate cost-effectiveness to 10 years post-transplant. Total mean treatment cost per patient to year 1 post-transplant was €62 075 vs. €59 767 for rATG versus basiliximab (P < 0.01). rATG therapy was associated with similar treatment costs to basiliximab by year 2, and a predicted cumulative treatment cost saving of €4 259 under rATG versus basiliximab by year 10 post-transplant. The mean number of quality-adjusted life years (QALYs) per patient by year 1 was 0.809 vs. 0.802 in the rATG and basiliximab cohorts, respectively (P = 0.38), with cumulative QALYs of 6.161 and 6.065 per patient by year 10. By year 2, the cumulative cost per QALY was slightly lower under rATG (€35 378) than basiliximab (€35 885), progressing to a saving of €1 041 under rATG for the cumulative cost per QALY by year 10. In conclusion, this model indicates that rATG induction provides a modest increase in QALYs with lower long-term costs than basiliximab in deceased-donor high-risk kidney transplant patients.

ABSTRACT

BACKGROUND: Induction therapy in deceased donor kidney transplantation is costly, with wide discrepancy in utilization and a limited evidence base, particularly regarding cost-effectiveness. METHODS: We linked the United States Renal Data System data set to Medicare claims to estimate cumulative costs, graft survival, and incremental cost-effectiveness ratio (ICER - cost per additional year of graft survival) within 3 years of transplantation in 19 450 deceased donor kidney transplantation recipients with Medicare as primary payer from 2000 to 2008. We divided the study cohort into high-risk (age > 60 years, panel-reactive antibody > 20%, African American race, Kidney Donor Profile Index > 50%, cold ischemia time > 24 hours) and low-risk (not having any risk factors, comprising approximately 15% of the cohort). After the elimination of dominated options, we estimated expected ICER among induction categories: no-induction, alemtuzumab, rabbit antithymocyte globulin (r-ATG), and interleukin-2 receptor-antagonist. RESULTS: No-induction was the least effective and most costly option in both risk groups. Depletional antibodies (r-ATG and alemtuzumab) were more cost-effective across all willingness-to-pay thresholds in the low-risk group. For the high-risk group and its subcategories, the ICER was very sensitive to the graft survival; overall both depletional antibodies were more cost-effective, mainly for higher willingness to pay threshold (US $100 000 and US $150 000). Rabbit ATG appears to achieve excellent cost-effectiveness acceptability curves (80% of the recipients) in both risk groups at US $50 000 threshold (except age > 60 years). In addition, only r-ATG was associated with graft survival benefit over no-induction category (hazard ratio, 0.91; 95% confidence interval, 0.84-0.99) in a multivariable Cox regression analysis. CONCLUSIONS: Antibody-based induction appears to offer substantial advantages in both cost and outcome compared with no-induction. Overall, depletional induction (preferably r-ATG) appears to offer the greatest benefits.

ABSTRACT

The advent of new cell-based immunotherapies for leukemia offers treatment possibilities for certain leukemia subgroups. The wider acceptability of these new technologies in clinical practice will depend on its impact on survival and costs. Due to the small patient groups who have received it, these aspects have remained understudied. This non-randomized single-center study evaluated medical costs and survival for acute myeloid leukemia between 2005 and 2010 in 50 patients: patients treated with induction and consolidation chemotherapy (ICT) alone; patients treated with ICT plus allogeneic hematopoietic stem cell transplantation (HCT), which is the current preferred post-remission therapy in patients with intermediate- and poor-risk AML with few co-morbidities, and patients treated with ICT plus immunotherapy using autologous dendritic cells (DC) engineered to express the Wilms' tumor protein (WT1). Total costs including post- consolidation costs on medical care at the hematology ward and outpatient clinic, pharmaceutical prescriptions, intensive care ward, laboratory tests and medical imaging were analyzed. Survival was markedly better in HCT and DC. HCT and DC were more costly than ICT. The median total costs for HCT and DC were similar. These results need to be confirmed to enable more thorough cost-effectiveness analyses, based on observations from multicenter, randomized clinical trials and preferably using quality-adjusted life-years as an outcome measure.

ABSTRACT

IMPORTANCE: Adults with acute myeloid leukemia (AML) or myelodysplastic syndrome (MDS) typically remain hospitalized after induction or salvage chemotherapy until blood cell count recovery, with resulting prolonged inpatient stays being a primary driver of health care costs. Pilot studies suggest that outpatient management following chemotherapy might be safe and could reduce costs for these patients. OBJECTIVE: To compare safety, resource utilization, infections, and costs between adults discharged early following AML or MDS induction or salvage chemotherapy and inpatient controls. DESIGN: Nonrandomized, phase 2, single-center study conducted at the University of Washington Medical Center. Over a 43-month period (January 1, 2011, through July 31, 2014), 178 adults receiving intensive AML or MDS chemotherapy were enrolled. After completion of chemotherapy, 107 patients met predesignated medical and logistical criteria for early discharge, while 29 met medical criteria only and served as inpatient controls. INTERVENTIONS: Early-discharge patients were released from the hospital at the completion of chemotherapy, and supportive care was provided in the outpatient setting until blood cell count recovery (median, 21 days; range, 2-45 days). Controls received inpatient supportive care (median, 16 days; range, 3-42 days). MAIN OUTCOMES AND MEASURES: We analyzed differences in early mortality, resource utilization including intensive care unit (ICU) days, transfusions per study day, and use of intravenous (IV) antibiotics per study day), numbers of infections, and total and inpatient charges per study day among early-discharge patients vs controls. RESULTS: Four of the 107 early-discharge patients and none of the 29 control patients died within 30 days of enrollment (P=.58). Nine early-discharge patients (8%) but no controls required ICU-level care (P=.20). No differences were noted in the median daily number of transfused red blood cell units (0.27 vs 0.29; P=.55) or number of transfused platelet units (0.26 vs 0.29; P=.31). Early-discharge patients had more positive blood cultures (37 [35%] vs 4 [14%]; P=.04) but required fewer IV antibiotic days per study day (0.48 vs 0.71; P=.01). Overall, daily charges among early-discharge patients were significantly lower than for inpatients (median, $3840 vs $5852; P<.001) despite increased charges per inpatient day when readmitted (median, $7405 vs $5852; P<.001). CONCLUSIONS AND RELEVANCE: Early discharge following intensive AML or MDS chemotherapy can reduce costs and use of IV antibiotics, but attention should be paid to complications that may occur in the outpatient setting.

ABSTRACT

BACKGROUND: A watch and wait (WW) strategy is the standard of care for patients with asymptomatic advanced-stage follicular lymphoma. Recent data have demonstrated an improvement in the time to progression with rituximab induction (RI) with or without rituximab maintenance (RM) in comparison with a WW strategy wait in such patients. It remains unclear whether this is a cost-effective strategy. METHODS: A Markov decision analysis model was developed to compare the clinical outcomes, costs, and cost-effectiveness of RI (4 weekly doses) plus RM (12 doses every 2 months), RI (4 weekly doses), and a WW strategy for patients newly diagnosed with low-burden, asymptomatic advanced-stage follicular lymphoma over a lifetime horizon. Baseline probabilities and utilities were derived from a systematic review of published studies, and they were evaluated on a 6-month cycle. A Canadian public health payer's perspective was adopted, and costs were presented in 2012 Canadian dollars. RESULTS: RI was the cheapest strategy. It was less costly at $59,953 versus $67,489 for the RM arm and $75,895 for the WW arm. It was also associated with a slightly lower quality-adjusted life expectancy at 6.16 quality-adjusted life years (QALYs) versus 6.28 QALYs for the RM strategy but was superior to WW (5.71 QALYs). In sensitivity analyses of key variables, this effectiveness was sensitive to the probability of first and second progression in the RI arm, and this indicated relatively neutral effectiveness between the 2 rituximab arms. CONCLUSIONS: RI without maintenance for asymptomatic advanced-stage follicular lymphoma is the preferred strategy: it minimizes costs per patient over a lifetime horizon.

ABSTRACT

BACKGROUND: The IFCT-GFPC 0502 phase III study reported prolongation of progression-free survival with gemcitabine or erlotinib maintenance vs. observation after cisplatin-gemcitabine induction chemotherapy for advanced non-small-cell lung cancer (NSCLC). This analysis was undertaken to assess the incremental cost-effectiveness ratio (ICER) of these strategies for the global population and pre-specified subgroups. METHODS: A cost-utility analysis evaluated the ICER of gemcitabine or erlotinib maintenance therapy vs. observation, from randomization until the end of follow-up. Direct medical costs (including drugs, hospitalization, follow-up examinations, second-line treatments and palliative care) were prospectively collected per patient during the trial, until death, from the primary health-insurance provider's perspective. Utility data were extracted from literature. Sensitivity analyses were conducted. RESULTS: The ICERs for gemcitabine or erlotinib maintenance therapy were respectively 76,625 and 184,733 euros per quality-adjusted life year (QALY). Gemcitabine continuation maintenance therapy had a favourable ICER in patients with PS = 0 (52,213 €/QALY), in responders to induction chemotherapy (64,296 €/QALY), regardless of histology (adenocarcinoma, 62,292 €/QALY, non adenocarcinoma, 83,291 €/QALY). Erlotinib maintenance showed a favourable ICER in patients with PS = 0 (94,908 €/QALY), in patients with adenocarcinoma (97,160 €/QALY) and in patient with objective response to induction (101,186 €/QALY), but it is not cost-effective in patients with PS =1, in patients with non-adenocarcinoma or with stable disease after induction chemotherapy. CONCLUSION: Gemcitabine- or erlotinib-maintenance therapy had ICERs that varied as a function of histology, PS and response to first-line chemotherapy.

ABSTRACT

BACKGROUND: Induction chemotherapy for acute myeloid leukaemia (AML) is one of the most resource-intensive cancer therapies delivered in hospitals. AIMS: To assess the health resource impact of different chemotherapy approaches for AML commonly used in Australia. METHODS: A retrospective analysis was undertaken in 63 patients aged 18-55 years with AML given induction with either 7 + 3 (cytarabine 100 mg/m(2) days 1-7 and idarubicin 12 mg/m(2) days 1-3) or HiDAC-3 (high-dose cytarabine 3 g/m(2) twice daily days 1, 3, 5 and 7 and idarubicin 12 mg/m(2) days 1-3) chemotherapy. Average costs of hospitalisation, pathology, radiology, chemotherapy and ancillary drugs were calculated and compared with current Victorian casemix funding. Two consolidation approaches, HiDAC (cytarabine 3 g/m(2) twice daily days 1, 3, 5 and 7) × either three or four cycles (following 7 + 3) and IcE (idarubicin 12,mg/m(2) days 1-2, cytarabine 100 mg/m(2) × 5 days and etoposide 75 mg/m(2) × 5 days) × 2 cycles (following HiDAC-3) were modelled, using a policy of discharge following completion of chemotherapy with outpatient monitoring. RESULTS: The cost (in AUD) of induction was similar between 7 + 3 ($58,037) and HiDAC-3 ($56,902), with bed day costs accounting for 61-62% of the total expense. Blood bank costs ranked second, accounting for 15%. Accumulated costs for HiDAC consolidation were $44,289 for a three-cycle protocol and $59,052 for four cycles ($14,763 per cycle) versus $31,456 for two cycles of IcE consolidation ($15,728 per cycle). Overall, the classical 7 + 3 → HiDAC approach ($102,326/$117,089 for three or four consolidation cycles) incurs a greater cost than a HiDAC-3 → IcE × 2 approach ($88,358). For patients requiring complete hospitalisation until neutrophil recovery, the estimated costs of treatment will be even higher, ranging between $122,282 for HiDAC-3 → IcE × 2, $153,212 for 7 + 3 → HiDAC × 3 and $184,937 for 7 + 3 → HiDAC × 4. State-based casemix funding for non-complicated AML therapy is currently $74,013 for 7 + 3 → HiDAC × 4, $64,177 for 7 + 3 → HiDAC × 3 and $54,340 for HiDAC-3 → IcE × 2 based on outpatient recovery after consolidation chemotherapy. These calculations do not take into account additional resource implications associated with complications of consolidation chemotherapy or reinduction for treatment failure. CONCLUSION: Regimens minimising the total number of chemotherapy cycles may represent the most efficient use of limited health resources for the treatment of AML.

ABSTRACT

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.

ABSTRACT

INTRODUCTION: Head and neck carcinomas are among the most frequent tumor diseases and, because of different multimodal therapy options, cause enormous costs. For this reason, we examined whether in operable advanced head and neck carcinomas, neoadjuvant induction chemotherapy is cost effective in comparison with surgery followed by postoperative radio(chemo)therapy. MATERIAL AND METHODS: A Markov model was developed with paclitaxel, cisplatin and fluorouracil as induction therapy. The legal health insurance in Germany was chosen for cost perspectives, and a willingness-to-pay limit at EUR 38,000 was set. RESULTS: Total costs for surgery with postoperative radiochemotherapy amounted to EUR 13,999. Prior induction chemotherapy raised the costs to EUR 17,377, with a higher effectiveness by 0.1 years of life. Costs per year of life gained are EUR 33,780. The incremental cost effectiveness ratio (ICER) with variations in side effects for surgery and postoperative chemotherapy amounted to between EUR 31,520 and 36,050. With variations in side effects for induction chemotherapy, the ICER amounted to EUR 30,060-37,520. The Monte Carlo simulation disclosed cost effectiveness for 55.4% of the patients; for 44.6%, there was no cost effectiveness. CONCLUSION: The Markov-modeled cost effectiveness analysis indicates that with operable head and neck tumors, induction therapy with paclitaxel, cisplatin and fluorouracil is cost effective.

ABSTRACT

PURPOSE: To evaluate frequency and severity of adverse drug reactions (ADRs) and its economic consequences after standard dose (immuno-)chemotherapy (CT) of non-small-cell lung cancer (NSCLC). PATIENTS AND METHODS: Subanalysis of a prospective, multicentre, longitudinal, observational cohort study; data were collected from patient interviews and pre-planned chart reviews. Costs were aggregated per CT line and presented from provider perspective. RESULTS: A total of 120 consecutive NSCLC patients (mean age, 63.0 ± 8.4 (SD) years; men, 64.2%; ECOG (Eastern Cooperative Oncology Group) performance status <2, 84.3%; tumour stage III/IV, 85%; history of comorbidity, 93.3%) receiving 130 CT lines were evaluated. 80% of CT lines were associated with grade 3 or 4 ADRs, 22.3% developed potential life-threatening complications, 77.7% were associated with at least one hospital stay (inpatient, 63.9%; outpatient/day clinic 39.2%, ICU 6.9%), with a mean cumulative number of 12.8 (±14.0 SD) hospital days. Mean (median) toxicity management costs per CT line (TMC-TL) amounted to €3,366 (€1,406) and were found to be higher for first-line compared to second-line treatment: €3,677 (€1,599) vs. €2,475 (€518). TMC-TL were particularly high in CT lines with ICU care €12,207 (€9,960). Eight out of 11 ICU stays were associated with grade 3 or 4 infections. Nine CT lines with ICU care accounted for 25% of total expenses (€109,861 out of €437,580). CONCLUSIONS: In first-line NSCLC treatment, in particular, CT toxicity management is expensive. Asymmetric cost distribution seems to be triggered by infection associated ICU care. Its avoidance should reduce patients' clinical burden and have considerable economic implications. Nevertheless, comparative observational studies have to confirm estimated savings.

ABSTRACT

The aim of this study was to calculate the costs of the current initial treatment of acute myeloid leukemia. Resource use was collected for 202 patients who started with intensive chemotherapy in 2008 or 2009. The costs of the first induction course were significantly higher than the costs of the second induction course. Allogeneic transplantation from a matched unrelated donor was significantly more expensive than the other consolidation treatments. In-hospital stay was the major cost driver in the treatment of AML. Research regarding possibilities of achieving the same or better health outcome with lower costs is warranted.

ABSTRACT

BACKGROUND: Adding docetaxel (Taxotere, T) to induction chemotherapy with platinum/infusional 5-FU (PF) has been shown to improve overall survival of patients with head and neck cancer. The aim of the study was to analyze the cost-utility of TPF in patients with unresectable disease. DESIGN: We developed a Markov model to represent patient's weekly transitions among different health states, related to treatment or disease status. Transition probabilities were obtained from the TAX 324 clinical trial report and from the European Organization for Research and Treatment of Cancer (EORTC) 24971/TAX 323 raw data. Costs were estimated in Italy from a Regional Healthcare System perspective. A 5-year temporal horizon was adopted and a 3.5% yearly discount rate was applied. RESULTS: When compared with PF, TPF treatment increases life expectancy by 0.33 quality-adjusted life-years (QALYs) in TAX 323 and 0.41 QALYs in TAX 324. The benefit was achieved at a cost of €11,822/QALY for TAX 323 and €6757/QALY for TAX 324. Monte Carlo sensitivity analysis showed that 69% (TAX 323) and 99% (TAX 324) of the results lie below the threshold of €50,000/QALY saved. CONCLUSIONS: In our analysis, TPF induction chemotherapy proved to be cost-effective when compared with PF, having a cost-utility ratio comparable to other widely accepted healthcare interventions.
