INTRODUÇÃO: O presente trabalho teve como objetivo elaborar análise custoefetividade do esquema de quimiorradioterapia com cisplatina (estratégia 2) comparado ao tratamento radioterápico (estratégia 1) para pacientes portadores de CECCP localmente avançado não elegíveis para tratamento cirúrgico. MÉTODOS: levantamos dados prospectivos de 33 pacientes na estratégia 2 e dados retrospectivos de 29 pacientes tratados no HC-FMUSP e Hospital A.C. Camargo, (estratégia 1). Consideramos a tabela de reembolso do Sistema Único de Saúde (perspectiva SUS) e custos do HC-FMUSP com honorários profissionais, medicamentos, demais insumos e depreciação de equipamentos (perspectiva Institucional). A medida de efetividade foi 1 ano de vida ganho, livre de progressão da doença (SLPD). Calculamos a Razão Incremental Custo Efetividade (RICE). RESULTADOS: 31% dos pacientes da estratégia 1 e 58% na estratégia 2) tiveram 1 ano de SLPD. Na perspectiva SUS o custo total por paciente na estratégia 1 foi de R$ 2.798,52 e R$ 4.938,11 na estratégia 2. Na perspectiva institucional os custos foram R$ 26.798,52 e R$ 5.040,79, respectivamente. A RICE na perspectiva SUS foi de R$ 7.924,00 reais por ano de vida ganho e R$ 8.912,71 na perspectiva institucional. CONCLUSÃO: nas duas perspectivas a estratégia 2 se mostrou custo-efetiva, sendo o custo incremental considerado aceitável, segundo diretrizes do Banco Mundial.

Abstract in English
INTRODUCTION: The present study aims to conduct a cost-effectiveness analysis comparing chemoradiotherapy with cisplatine and radiotherapy alone, to treat inoperative advanced head and neck cancer. METHODS: we collected data from 29 patients in a prospective study on chemoradiotherapy with cisplatin, conducted at Hospital das Clínicas HC-FMUSP,(strategy 2). For strategy 1, we collected retrospective data of 33 patients treated with radiotherapy at HC-FMUSP and Hospital A.C. Camargo. We considered only direct costs (personnel, drugs, material and equipment depreciation). We considered, the National Health Service (SUS) reimbursement parameters as the National Security System perspective, and HC-FMUSP costs as the institutional perspectives. We measured effectiveness as one year of diseasefree life gained. We collected costs and effectiveness data and calculated the cost-effectiveness incremental ratio ICER, which expresses additional costs per life year gained, in strategy 2, compared to strategy 1 RESULTS: 31.0% of the patients treated in strategy 1 lived more than 12 months, without disease progression, compared to 58.0% of the patients in strategy 2. According to SUS perspective, the total cost per patient in strategy 1) is R$ 2.798,52 and R$ 4.938,11 in strategy 2. Considering the institutional perspective, total costs are R$ 2.634,36, and R$ 5.040,79 respectively. In SUS perspective, the ICER ratio of strategy 2 compared to 1 is R$ 7.924,00 per lifes year gained. In the institutional perspective, ICER is R$ 8.912,71. We conducted a one way sensitivity analysis to verify our calculations. CONCLUSION: Chemoradioterapy with cisplatin proved more cost-effective than radiotherapy. Using the World Bank guidelines, wich considers the countries GDP per capita an acceptable cost per additional year of life (R$ 12.491,00 in 2006), the incremental cost of both is acceptable.
