RESUMEN
The 5-year completed treatment analysis of the Anastrozole and Tamoxifen-Alone or in Combination (ATAC) trial showed the superiority of anastrozole over tamoxifen for reduction of disease progression in patients with hormone receptor-positive (HR+) early breast cancer (EBC). The objective was to evaluate the cost-effectiveness of anastrozole versus tamoxifen in this setting. A health economic model was developed comparing the natural history of EBC patients treated with anastrozole or tamoxifen. The perspective of the Belgian health care system was taken. Disease progression from EBC was obtained from the ATAC trial and further progression beyond the clinical trial from published literature. Resource use data were obtained from the ATAC study and from published local retrospective data. Anastrozole was cost-effective versus tamoxifen, provided that a time horizon of at least 9 years is taken. This sensitivity to time horizon is inherently associated with the adjuvant setting due to the different evolution of costs and outcomes over time. Costs are incurred solely during the first 5 years, whereas outcomes are cumulated beyond adjuvant treatment. In conclusion, provided that a sufficient time horizon is taken and that long-term model predictions are confirmed from further follow-up from the ATAC study, anastrozole is a highly cost-effective adjuvant therapy compared to tamoxifen.

Based on Medline search, a summary is provided of recent health economic evidence in published literature relating to the management of multiple myeloma. The following major components of current multiple myeloma treatments are discussed: induction chemotherapy, high-dose chemotherapy supported by autologous peripheral stem cell transplantation (ASCT), long-term biphosphonates therapy to prevent skeletal events and recent advances for the treatment of relapsed or refractory multiple myeloma and under evaluation in primary treatment (thalidomide and bortezomib). Our study shows that there still appears to be a need for health economic information to confirm the cost-effectiveness of stem cell support versus high-dose chemotherapy without stem cell support, as well as to assess optimal biphosphonate treatment regimens. There is also a clear need for peer reviewed economic evaluations of novel therapies such as thalidomide and Bortezomib in the treatment of multiple myeloma at different stages of the disease.

Emerging pathogens continue to threaten blood safety, requiring novel safety approaches. INTERCEPT Blood System for platelets (IBSP) inactivates pathogens, aiming at eliminating the risk of transmitting current and emerging pathogens. The objective was to evaluate the incremental cost-effectiveness ratio (ICER) for IBSP in Belgium. A decision model comparing a 'world with IBSP' to a 'world without IBSP' calculates lifetime costs and 'quality adjusted life years' (QALYs) following platelet transfusion in different indications. Disease-specific life expectancy and consequences of transfusion-transmitted infections were obtained from literature. Transfusion safety and costs were obtained from official sources. Hepatitis C virus-like emerging pathogen was simulated. A wide range of ICERs was observed, highly sensitive to the risk of emerging pathogen trans- mission, underlying disease and age. In the most conservative approach, ICER ranged from 3,459,201 Euro/QALY in absence of emerging pathogen to 195,364 Euro/QALY. The mean threshold of emerging infection risk for IBSP dominance (saving money and producing health gains) ranged from 1/1,079 to 1/2,858 transfusions. Considering the high value authorities appear to place on preventing accidental injury, and ICER of recent implementations in transfusion medicine (NAT: up to 2.3 million Euro per lifeyear), IBSP can be considered cost-effective, taking into account the potential risk of emerging pathogens.

Systemic fungal infections remain a major clinical problem in immunocompromised patients. Presumed systemic fungal infections (PSFI) are treated empirically with an intravenous antifungal agent to reduce the occurrence of documented infections and associated mortality. The objective of this study was to compare the cost-effectiveness of intravenous itraconazole (IVitra) treatment with the current first-line empirical treatment of PSFI with conventional amphotericin B (CAB) in cases of neutropenic cancer and bone marrow transplantation (BMT). Cost-effectiveness was expressed as cost per additional "responder" (defined as a patient without fever or major toxicity). We developed a medical decision analytical tree that included probabilities of toxicity, response and pathogen documentation, and second-line treatments. Clinical data were obtained from randomized clinical trials, and resource use data were obtained from a panel of clinical experts. The total cost of treating PSFI per neutropenic cancer patient was lower for IVitra than for CAB, and this lower cost resulted from a reduced need for second-line antifungals. In a cost-effectiveness analysis, IVitra treatment was superior to CAB treatment. Compared with current treatment with CAB, IVitra therapy was shown to be a cost-effective and cost-saving empirical treatment for PSFI in neutropenic cancer patients and BMT patients.

BACKGROUND: Since the incidence of breast cancer is growing, prevention programs can be expected to have a large economic impact on the health care system. From a health economic point of view, one is interested in the costs saved by disease prevention. PATIENTS AND METHODS: To predict 10-year cumulative incidence-based costs of postmenopausal breast cancer, a state transitional model was developed based on published clinical data. The model simulates disease progression and includes nine health states of 1 year: node-negative and node-positive early cancer; local relapse; metastasis, each with its follow-up states; and death. The cost per state was obtained from a chart review in 118 patients with different disease states. Costs were calculated from the health insurance perspective and discounted at 3%. RESULTS: The cumulative 10 year cost per patient was equal to 31,774 euro [95% confidence interval (CI) 30,536-33,012 euro] of which 30% was hospital costs, 28% systemic treatment, surgery and radiotherapy and 14% testing. Costs were at their highest following diagnosis and before death. CONCLUSIONS: This incidence-based approach identified the cost of postmenopausal breast cancer over time and may serve as a valid baseline for assessment of new interventions in prevention or early treatment.

Hyperuricemia (HU) and tumour lysis syndrome (TLS) are complications of acute leukaemia and non-Hodgkin lymphoma (NHL) leading to increased morbidity and mortality. The objective of this study was to define incidence and calculate health care cost associated with HU and TLS. 788 acute leukaemia and NHL patients from Belgium, The Netherlands, Spain and UK were screened retrospectively for HU and TLS. Resource use related to HU and TLS was recorded and costs were calculated applying local unit costs. Results showed that HU occurred in 18.9% of patients, and 27.8% of them fulfilled TLS criteria. The cost of HU without TLS was 672 euros (SE 181), the cost of TLS 7,342 euros (SE 1,412). TLS requiring dialysis incurred an average cost of 17,706 euros. In conclusion, it is noted that the observed incidence rates were lower than earlier reports. In addition, some risk factors for HU and TLS (e.g. paediatric patients versus adults) were not associated with increased rates of HU or TLS as a consequence of higher rates of prevention. TLS cases incurred 11 times higher costs than HU cases in which TLS was absent. The main cost drivers in TLS are interventions requiring intensive care.

GOALS: Hyperuricaemia (HU) and tumour lysis syndrome (TLS) are complications of acute myeloid/lymphoid leukaemia (AML/ALL) and non-Hodgkin lymphoma (NHL) leading to increased morbidity and mortality. The objective was to assess incremental cost-effectiveness ratios (ICER) of preventing/treating HU and TLS with recombinant urate oxidase, rasburicase (Fasturtec/Elitek). PATIENTS AND METHODS: Incidence and costs of HU and TLS were based on a multi-country chart review. Life expectancy at the time of diagnosis was based on published survival rates and age at diagnosis. Reductions of HU/TLS following treatment with rasburicase were based on clinical trial data. RESULTS: Prevention with rasburicase appears highly cost-effective in children (ICER between Eur 425 and Eur 3054 per life-year saved, LYS). In adults, prevention is more cost-effective in NHL and ALL (maximum ICER of Eur 41383 and Eur 32126 per LYS). Treatment of established HU/TLS with rasburicase is cost-saving in children and highly cost-effective in adults. The results are robust in children. In adults, the prevention strategy appears sensitive to the risk of HU/TLS. CONCLUSIONS: In conclusion, rasburicase, in addition to the demonstrated clinical benefit, is an economically attractive new option in the treatment of HU, both in adults and children. In prevention the drug has an attractive economic profile in children, and is cost-effective in adults with ALL and NHL.

OBJECTIVES: Despite optimal pharmacological treatment a large proportion of patients with atrial fibrillation (Afib) are not arrhythmia-free, and remain at risk for complications such as stroke and cardiac morbidity. If first-line treatment fails, most patients receive second-line pharmacological treatment. The emergence of new technologies aimed at restoring and maintaining sinus rhythm, such as catheter ablation techniques, has increased the interest in the economic aspects of second-line pharmacological treatment. The objective was therefore to calculate the 5-year direct medical costs of second-line pharmacological management of paroxysmal and persistent Afib in France. METHODS: The analysis was based on clinical and economic literature and the input of cardiologists-electrophysiologists. The analysis included probabilities of stroke, sudden cardiac death, other cardiac and noncardiac death, direct medical costs of drugs, follow-up and complications from the healthcare payer's perspective. Included treatment strategies were (1) rhythm control with class Ic and III antiarrhythmics and (2) rate control, consisting of digoxin combined with a beta-blocker or calcium antagonist. Both strategies included aspirin or anticoagulation therapy. RESULTS: The average total 5-year cost of Afib was 16,539 Euro (FF 108,486) per patient. The result was stable to sensitivity analysis on incidence of stroke and type of stroke prevention. The main cost drivers were follow-up visits and hospitalizations and the cost of congestive heart failure. Both items being subject to some variation, they were submitted to sensitivity analysis showing minimal 5-year costs still over 14,483 Euro (FF 95,000). CONCLUSIONS: Afib management places high demands on medical resources mainly through its complications and comorbidity.
