Abstract in Portuguese
Objetivo: Estimar a utilização de recursos e custos diretos relacionados à terapia endócrina (TE) versus quimioterapia (QT) no tratamento de câncer de mama avançado (CMA) receptores hormonais positivos (RH+) em pacientes pós menopáusicas,depois de pelo menos uma TE anterior. Métodos: Estudo longitudinal retrospectivo analisou pacientes pós menopáusicas com CMA em tratamento com fulvestranto ou QT entre 2006 e 2008, em um serviço público de oncologia ambulatorial. Apenas pacientes sem crise visceral e com pelo menos uma terapia anterior hormonal foram considerados elegíveis. Os prontuários foram revisados e as informações sobre diagnóstico, tratamento, e utilização de recursos foram obtidas. Resultados: As pacientes eram do sexo feminino e a idade média foi de 64,6 ± 12,6 anos. As pacientes estavam bem balanceados entre os grupos, considerando as características basais. Vinte e cinco pacientes foram incluídas no estudo, 13 pacientes receberam QT e 12 pacientes receberam fulvestranto. O esquema de QT mais usado foi o regime com paclitaxel (n = 5, 38%). O número médio de ciclos foi de 7,6 e 5,8 para fulvestranto e QT, respectivamente. O custo médio de tratamento por paciente foi de R$ 16.679 (USD11,914, 2005 índice de paridade de poder de compra 1USD = 1,4BRL) para fulvestranto e BRL 32946 (USD 23, 533) para QT. O custo médio por ciclo foi de R$ 2,199 (US$ 1,571) e BRL 5,710 (USD 4,079) para fulvestranto e QT, respectivamente, resultando em BRL 3,511(USD 2,508) de custo incremental por ciclo. Conclusões: Nossos resultados indicam que TE com fulvestranto pode ser economicamente adequada em pacientes com CMA RH + que falharam a pelo menos uma linha anterior de TE. Futuras pesquisas são necessárias para validar estes resultados em outros contextos, mas consideramos que as nossas estimativas refletem o mundo real da prática clínica no Brasil

Abstract in English
OBJECTIVES: To estimate the resource utilization and costs related to endocrine therapy (ET) versus chemotherapy (CT) in the treatment of hormonal receptor positive (HR+), advanced breast cancer (ABC) patients, after at least one previous ET. METHODS: This retrospective longitudinal study analyzed ABC patients treatment with fulvestrant or CT between 2006 and 2008 in a public oncology outpatient service. Only patients without visceral crisis and with at least one previous hormonal therapy were considered eligible. Medical charts were reviewed by two investigators and information about diagnosis, course of treatment, and resource utilization was obtained. RESULTS: Patients were all female and the mean age was 64,6 ± 12,6 years. Patients were well matched between groups considering baseline characteristics. Twenty-five patients were enrolled in the study, 13 patients received CT and 12 patients received fulvestrant. The most common CT regimen was paclitaxel (n = 5, 38%). The mean number of cycles was 7,6 and 5,8 for fulvestrant and CT, respectively. The mean treatment cost per patient was BRL 16,679 (USD 11,914; 2005 purchasing power parity index 1USD = 1.4BRL) for fulvestrant and BRL 32,946 (USD 23,533) for CT. The mean cost per cycle was BRL 2,199 (USD 1,571) and BRL 5,710 (USD 4,079) for fulvestrant and CT, respectively, resulting in BRL 3,511 (USD 2,508) incremental cost per cycle. CONCLUSIONS: Our study results indicate that subsequent ET with fulvestrant can be economically appropriate among HR+ ABC patients. Further researches could validate these findings in other contexts, but we consider that our estimations reflect the real world clinical practice in Brazil
