ABSTRACT

BACKGROUND: Allogeneic hematopoietic stem cell transplantation with HLA-identical donors has been established for the treatment of acute myeloid leukemia patients for over 30 years with a cure rate of 50 percent to 60 percent. OBJECTIVES: To analyze the overall survival of patients and identify factors that influence the outcomes of this type of transplant in patients in 1st complete remission who received a busulfan and melphalan combination as conditioning regimen. METHODS: Twenty-five consecutive patients with acute myeloid leukemia were enrolled between 2003 and 2008. The median age was 34 years old (Range: 16 - 57 years). All patients received cyclosporine and methotrexate for prophylaxis against graft-versus-host disease. Median neutrophil engraftment time was 16 days (Range: 7 - 22 days) and 17 days (Range: 7 - 46 days) for platelets. Sinusoidal obstructive syndrome was observed in three patients, seven had grade II acute graft-versus-host disease and one extensive chronic graft-versus-host disease. RESULTS: The overall survival by the Kaplan-Meier method was 48 percent after 36 months with a plateau at 36 months after transplantation. Intensive consolidation with high-dose arabinoside resulted in an improved survival (p-value = 0.0001), as did grade II acute graft-versus-host disease (p-value = 0.0377) and mild chronic graft-versus-host disease (p-value < 0.0001). Thirteen patients died, five due to infection within 100 days of transplant, two due to hemorrhages, one to infection and graftversus-host disease and three relapses followed by renal failure (one) and infection (two). The cause of death could not be determined for two patients. CONCLUSION: The busulfan and melphalan conditioning regimen is as good as other conditioning regimens providing an excellent survival rate.

ABSTRACT

O transplante de células tronco hematopoéticas alogênico e autogênico na leucemia mielóide aguda em primeira remissão completa: analise de 62 pacientes. Os pacientes foram submetidos a transplante de células tronco hematopoéticas alogênico e autogênico. Ao final do estudo estavam vivos no alogênico 43,3% e no autogênico 62,5%. Consolidação intensiva teve melhor sobrevida no alogênico. Os pacientes com DECH aguda grau II tiveram melhor sobrevida. Dois pacientes com DECH crônica extensa morreram. Óbito por infecção ocorreu com maior freqüência no alogênico seguido de recidiva. No autogênico a recidiva foi a principal causa de óbito. Morte por toxicidade ocorreu em 47% dos pacientes que foram a óbito no alogênico e em 8,3% no autogênico. Na analise múltipla de Cox a consolidação intensiva e DECH crônica, tiveram significância...


The allogeneic and autologous hematopoietic stem cell transplantation in acute myeloid leukemia in first complete remission: analyses of 62 patients. The patients were submitted to allogeneic and autologous hematopoietic stem cell transplantation. The end of the study were kept alive in allogeneic 43,3% and in autologous 65,2%. Patient in allogeneic who were consolidated had better survival. Patients with acute GVHD grade II had better survival. Two patients with chronic GVHD in intense, died. Infection was the most frequent dead cause in allogeneic following relapse. In autologous the relapse was the principal cause of death. Toxicity occurred in 47% of patients who died in allogeneic and 8,3% in autologous. In cox multiple analyses intensive consolidation and chronic GVHD had significance...

ABSTRACT

CONTEXTO E OBJETIVO: A daunorrubicina lipossomal tem sido usada no tratamento em várias doenças hematológicas malignas, incluindo mieloma múltiplo (MM). O objetivo deste estudo foi avaliar a eficácia, efeitos colaterais e toxicidade da daunorrubicina lipossomal and dexametasona no Protocolo DD. TIPO DE ESTUDO E LOCAL: Estudo prospectivo, realizado nos hospitais Sírio Libanês, São Camilo, Brasil e no Hospital Alemão Oswaldo Cruz. MÉTODOS: 20 pacientes com MM ativo receberam daunoxome (25-30 mg/m²/dia) por três dias consecutivos, mensal, por quatro meses (total de quatro ciclos), e dexametasona, 10 mg a cada seis horas por quatro dias consecutivos (dia 1 - 4, 9 - 12 e 17 - 20), também mensal. RESULTADOS: A mediana entre o diagnóstico e o início do protocolo DD foi de 13 meses. Quinze pacientes receberam alguma quimioterapia anterior ao protocolo DD. Uma redução maior que 50% do pico monoclonal sérico foi observada em seis paciente após o primeiro ciclo do DD (30%), em seis pacientes após o segundo ciclo (30%), em quatro pacientes após o terceiro ciclo (20%) e em quatro pacientes não houve redução (20%). No início do protocolo, 17 pacientes (85%) apresentavam anemia e em 12 destes pacientes (70%) a anemia foi corrigida. Doença progressiva foi observada em três pacientes (15%), um apresentava resposta mínima, quatro pacientes (20%) apresentaram resposta parcial e 12 (60%) apresentaram resposta completa. A toxicidade hematológica foi aceitável.Toxicidade em trato gastrointestinal foi leve, consistindo em náusea (10%) e anorexia (15%), sem episódios de vômito. CONCLUSÃO: Este tratamento apresentou uma baixa toxicidade, uma boa taxa de resposta e pode ser usado previamente ao transplante de medula óssea autogênico.
