RESUMO

OBJETIVO:

Estimar o impacto orçamentário do trastuzumabe subcutâneo, comparado com o in-travenoso, no Sistema de Saúde Suplementar (SSS) para o tratamento do câncer de mama inicial e metastático HER-2 positivo.

MÉTODOS:

Foi realizada uma análise de impacto orçamentário na perspectiva do SSS. Os tratamentos de câncer de mama inicial foram trastuzumabe em monoterapia e trastuzumabe com paclitaxel ou docetaxel. No câncer de mama metastático, considerou-se trastu-zumabe associado com docetaxel ou paclitaxel na primeira linha e em monoterapia na segunda linha. Para ambos, comparou-se a substituição do trastuzumabe intravenoso pelo subcutâneo. Uma pesquisa com 28 operadoras mapeou taxas, preços e tabelas de referência usadas para o reembolso de medicamentos, materiais e procedimentos. Uma equipe multidisciplinar estimou o uso de recur-sos. Custos médicos diretos foram incluídos e os preços foram obtidos de fontes públicas. O horizon-te temporal foi cinco anos e considerou-se a incorporação progressiva de trastuzumabe subcutâneo com 20% no primeiro ano até atingir 100%.

RESULTADOS:

Estimaram-se 31.589 pacientes com câncer de mama no SSS em cinco anos. O uso progressivo de trastuzumabe subcutâneo em comparação com o intravenoso levou a uma economia de 962,7 mBRL, 14,5 mBRL, 1,5 mBRL e 0,2 mBRL no SSS, para operadoras de saúde de grande, médio e pequeno porte, respectivamente. Materiais e procedimentos de suporte com taxas médicas foram os parâmetros mais sensíveis.

CONCLUSÃO:

O trastuzumabe subcutâneo em comparação com o intravenoso pode levar a uma economia de até 962,7 mBRL no tratamento do câncer de mama no SSS.
ABSTRACT

Objective:

To estimate the budgetary impact of subcutaneous trastuzumab, compared with intravenous trastuzumab, in the Brazilian Private Healthcare System (PHS), to treat early and metastatic HER-2 positive breast cancer.

Methods:

Budgetary impact analysis was performed in PHS perspective. For early breast cancer, treatment options were trastuzumab monotherapy, and trastuzumab plus paclitaxel or docetaxel, after adjuvant chemotherapy. For metastatic breast cancer, trastuzumab was combined with docetaxel or paclitaxel in the first line, and it was given in monotherapy in the second line. For both, a comparison of switching from intravenous to subcutaneous therapy was made. A survey was performed with 28 health maintenance organizations to map fees and sources used for reimbursement of drugs, materials and procedures. Direct medical costs were included. Time horizon was 5 years and market share of subcutaneous trastuzumab vary from 20% to 100%. Results were presented according to size of health maintenance organizations and a deterministic sensitivity analysis was conducted to analyze model robustness.

Results:

In 5 years, 31,589 breast cancer patients were estimated for the PHS, 284 patients for big, 30 patients for medium, and 6 patients for small HMOs. The progressive uptake of subcutaneous trastuzumab, compared with in-travenous formulation, can save up to 962,7 mBRL, 14,5 mBRL, 1,5 mBRL and 0,2 mBRL, respectively. Materials and support procedures along with medical fees were the most sensitive parameters. Con-clusion Compared with the intravenous administration, subcutaneous trastuzumab can save up to 962,7 mBRL costs in the breast cancer treatment in the Brazilian PHS
