RESUMO
Introdução: A estimativa do Instituto Nacional de Câncer José Alencar Gomes da Silva para o Brasil, para cada ano do biênio 2018-2019, foi de 59.700 novos casos de câncer de mama, com um risco estimado de 56,33 casos a cada 100 mil mulheres. Em 2014, os gastos públicos com atenção oncológica foram de aproximadamente R$ 2,5 bilhões. Objetivo: Avaliar o impacto dos custos diretos médicos em pacientes com carcinoma mamário tratados com tamoxifeno pelo Sistema Único de Saúde. Método: Estudo exploratório de custo da doença, quantitativo, retrospectivo, com caráter de prevalência e de abordagem bottom-up. A coleta dos dados foi realizada no ambulatório de Oncologia do Hospital São Vicente em Curitiba, Paraná. Resultados: A média do custo do tratamento dos pacientes foi R$ 14.497,70 em tratamento neoadjuvante ou adjuvante e de R$ 9.108,60 em tratamento paliativo. Em relação a essas variáveis, o custo do tamoxifeno foi o que mais impactou em relação ao custo total do tratamento, representando mais de 80% deste valor. A média do custo anual gasto com tamoxifeno por paciente foi de R$ 1.947,60. Conclusão: O custo médio do tratamento demonstrou ser alto em relação à média salarial dos brasileiros de R$ 2.110.00 (IBGE-2017). Os custos levantados neste estudo podem auxiliar os gestores de saúde pública em estratégias para racionalização dos gastos, otimização do capital e manutenção do atendimento à população.
Introduction: The estimate of the National Cancer Institute José Alencar Gomes da Silva, for each year of the 2018-2019 biennium in Brazil, was 59,700 new cases of breast cancer, with an estimated risk of 56.33 cases per 100,000 women. In 2014, public expenditures on cancer care were approximately R$ 2.5 billion. Objective: To evaluate the impact of direct medical costs on breast cancer patients treated with tamoxifen using the Unified Health System. Method: Prospective, quantitative, retrospective, cost-of-disease study with prevalence and bottom-up approach. Data collection was performed at the Oncology Outpatient Clinic of the Hospital São Vicente in Curitiba, Paraná. Results: The mean cost of the treatment was R$ 14,497.70 for neoadjuvant or adjuvant treatment and R$ 9,108.60 for palliative treatment. In relation to these variables, the cost of tamoxifen was the one that most impacted, in relation to the total cost of the treatment, representing more than 80% of this value. The mean annual cost of tamoxifen per patient was R$ 1,947.60. Conclusion: The average cost of treatment was high in relation to the Brazilian average salary of R$ 2,110.00 (IBGE-2017). The costs investigated in this study can help public health managers in strategies to rationalize expenditures, optimize capital and maintain patient care.

BACKGROUND: The pharmacotherapy of chronic myeloid leukaemia (CML) is mainly based on tyrosine kinase inhibitors (TKIs). The aim of this study was to compare the efficacy and safety of all TKIs in CML patients. METHODS: We conducted a systematic review with network meta-analysis (NMA) of randomised controlled trials (RCTs), including imatinib, nilotinib, dasatinib, bosutinib, radotinib and ponatinib. Searches were performed in PubMed, Scopus, Web of Science and SciELo (March 2018). The NMAs were built for six outcomes at 12 months: complete cytogenetic response (CCyR), major cytogenetic response (MCyR), deep molecular response, major molecular response (MMR), complete haematologic response and incidence of serious adverse events. We conducted rank order and surface under the cumulative ranking curve (SUCRA) analyses. RESULTS: Thirteen RCTs were included (n = 5079 patients). Statistical differences were observed for some comparisons in all outcomes. Imatinib 400 mg was considered the safest drug (SUCRA values of 10.3%) but presented low efficacy. Overall, nilotinib 600 mg was superior to the other TKI in efficacy (SUCRA values of 61.1% for CCyR, 81.0% for MMR, 90.0% for MCyR); however, no data on its safety profile at 12 months were reported. INTERPRETATION: Our results suggest that nilotinib should be upgraded to first-line therapy for CML, although further cost-effectiveness analyses, including the new TKI (i.e., ponatinib, radotinib), are needed.

OBJECTIVES: The aim of this study was to evaluate the direct costs of type 2 diabetes mellitus patients treated in a Brazilian public hospital. METHODS: This was an exploratory retrospective cost-of-illness study with quantitative approach, using medical records of patients treated in a public hospital (2012-14), with at least one consultation over a period of 12 months. Data on patient's profile, exams, number of consultations, medications, hospitalizations, and comorbidities were collected. The cost per patient per year (pppy) was calculated as well as the costs related to glycated hemoglobin (HbA1c) values, using thresholds of 7 and 8 percent. RESULTS: Data of 726 patients were collected with mean age of 62 ± 11 years (68.3 percent female). A total of 67.1 percent presented HbA1c > 7 percent and 44.9 percent > 8 percent. The median cost of diabetes was United States dollar (USD) 197 pppy. The median costs of medication were USD 152.49 pppy, while costs of exams and consultations were USD 40.57 pppy and 8.70 pppy, respectively. Thirty-eight patients (4 percent) were hospitalized and presented a median cost of 3,656 per patient per hospitalization with a cost equivalent to 53.1 percent of total expenses. Total costs of patients with HbA1c ≤ 7 percent were lower for this group and also costs of medications and consultations, whereas for patients with HbA1c ≤ 8 percent, only total costs and costs of medications were lower when compared with HbA1c > 8 percent patients. CONCLUSIONS: Medications and hospitalizations were the major contributor of diabetes expenses. Preventing T2DM, or reducing its complications through adequate control, may help avoid the substantial costs related to this disease.

The aim of this study was to conduct a cost-utility study of adefovir, entecavir, interferon alpha, pegylated interferon alpha, lamivudine and tenofovir for chronic hepatitis B in the context of Brazilian Public Health Care System. A systematic review was carried out for efficacy and safety. Another review was performed to collect utility data and transition probabilities between health states. A Markov model was developed in a time horizon of 40 years with annual cycles for three groups of: HBeAg positive, HBeAg negative, and all patients. These strategies were compared to a fourth group that received no treatment. Discount rates of 5% were applied and sensitivity analyses were performed. Tenofovir offered the best cost-utility ratio for the three evaluated models: U$397, U$385 and U$384 (per QALY, respectively, for HBeAg positive, negative, and all patients). All other strategies were completely dominated because they showed higher costs and lower effectiveness than tenofovir. The sequence of cost-utility in the three models was: tenofovir, entecavir, lamivudine, adefovir, telbivudine, pegylated interferon alpha, and interferon alpha. In the sensitivity analysis, adefovir showed lower cost-utility than telbivudine in some situations. The study has some limitations, primarily related to the creation of scenarios and modeling. In this study, tenofovir presented the best cost-utility ratio. The results obtained in this study will be valuable in decision-making and in the review of the clinical protocol, mainly involving the allocation of available resources for health care.

Treatment for chronic hepatitis B in Brazil are funded by the Ministry of Health and by the state Departments of Health. Clinical protocol and therapeutic guidelines approve the use of adefovir, entecavir, interferon-α, lamivudine, and tenofovir for the treatment of chronic hepatitis B. The aim of this study was to establish the profile of users of these drugs in the state of Paraná. A cross-sectional study was conducted with patients under treatment in Paraná in August 2011. The following data were obtained: gender, hepatitis B used drug, International Classification of Diseases, and regional health unit. The monthly cost of these drugs for the public health system was also calculated. 1,093 patients registered were found, 70% male, and 2.6% co-infected with the delta agent. Tenofovir was the drug most commonly used (355 users). The highest prevalence was found in the regional health units of Pato Branco, Cascavel, Foz do Iguaçú, Francisco Beltrão, Toledo, Londrina, and Maringá. The annual cost for the public health system in Paraná was U$1,066,867. Through this study it was possible to investigate the distribution and profile of users of drugs for the treatment of chronic hepatitis B in Paraná in August 2011.
