Abstract
- CONTEXT AND OBJECTIVE: For the last nine years, hematologists and oncologists have gathered annually at an educational symposium organized by a Brazilian and an American hospital. During the 2015 Board Review, a survey among the attendees evaluated the differences in management and treatment methods for multiple myeloma (MM). DESIGN AND SETTING: Cross-sectional study during an educational hematology symposium in São Paulo, Brazil. METHODS: Hematologists present at the symposium gave responses to an electronic survey by means of mobile phone. RESULTS: Among the 350 attendees, 217 answered the questionnaire. Most of the participants believed that immunotargeting agents (iTA) might be effective for slowing MM progression in heavily pretreated patients (67%) and that continued exposure to therapy might lead to emergence of resistant clones in patients with MM (76%). Most of the physicians use maintenance therapy after hematopoietic stem cell transplantation (95%) and 45% of them would further restrict it to post-transplantation patients with underlying high-risk disease. The first-line drugs used for transplantation-ineligible patients (TI-MM) were bortezomib-thalidomide-dexamethasone (31%), bortezomib-dexamethasone (28%), lenalidomide-dexamethasone (Rd; 17%) and melphalan-based therapy (10%). Lenalidomide was the drug of choice for post-transplantation maintenance for half of the participants. No significant differences were observed regarding age or length of experience. CONCLUSION: The treatment choices for TI-MM patients were highly heterogenous and the melphalan-based regimen represented only 10% of the first-line options. Use of maintenance therapy after transplantation was a common choice. Some results from the survey were divergent from the evidence in the literature. RESUMO CONTEXTO E OBJETIVOS: Há nove anos, hematologistas e oncologistas se reúnem anualmente em um simpósio educacional organizado por um hospital brasileiro e outro norte-americano. Durante o Board Review 2015, uma pesquisa foi conduzida entre os participantes e avaliou as diferenças na conduta e opções de tratamento para o mieloma múltiplo (MM). DESENHO E LOCAL: Estudo transversal no simpósio educacional de hematologia em São Paulo. MÉTODOS: Hematologistas presentes no simpósio responderam a uma pesquisa por celular. RESULTADOS: Dos 350 inscritos, 217 responderam o questionário. A maioria dos participantes acredita que a terapia-alvo imune (iTA) pode ser efetiva para desacelerar a progressão do MM em pacientes que já foram muito tratados previamente, e que a exposição contínua à terapia pode gerar clones resistentes em pacientes com MM (76%). A maioria usa terapia de manutenção após transplante de células-tronco hematopoiéticas (95%) e 45% dos médicos a restringiriam a pacientes pós-transplante com doença de base de alto risco. As drogas de primeira linha adotada para os pacientes inelegíveis para transplante (PIT) foram bortezomibe-talidomida-dexametasona (31%), bortezomibe-dexametasona (28%), lenalidomina-dexametasona (Rd; 17%) e terapia baseada em melfalan (10%). A lenalidomida foi a droga de escolha para a manutenção pós-transplante para metade dos participantes. Nenhuma diferença significativa foi encontrada para idade ou tempo de experiência. CONCLUSÃO: As escolhas de tratamento para PIT foram altamente heterogêneas e o regime baseado em melfalan representou somente 10% das opções de primeira linha. Terapia de manutenção após transplante é opção comum. Alguns dos resultados do levantamento foram divergentes das evidências na literatura.
