ABSTRACT

Abstract Objective: To describe the epidemiological profile and the survival rate of patients with acute myeloid leukemia (AML) in a state reference pediatric hospital. Method: Clinical-epidemiological, observational, retrospective, descriptive study. The study included new cases of patients with AML, diagnosed between 2004 and 2012, younger than 15 years. Results: Of the 51 patients studied, 84% were white; 45% were females and 55%, males. Regarding age, 8% were younger than 1 year, 47% were aged between 1 and 10 years, and 45% were older than 10 years. The main signs/symptoms were fever (41.1%), asthenia/lack of appetite (35.2%), and hemorrhagic manifestations (27.4%). The most affected extra-medullary site was the central nervous system (14%). In 47% of patients, the white blood cell (WBC) count was below 10,000/mm3 at diagnosis. The minimal residual disease (MRD) was less than 0.1%, on the 15th day of treatment in 16% of the sample. Medullary relapse occurred in 14% of cases. When comparing the bone marrow MRD with the vital status, it was observed that 71.42% of the patients with type M3 AML were alive, as were 54.05% of those with non-M3 AML. The death rate was 43% and the main proximate cause was septic shock (63.6%). Conclusions: In this study, the majority of patients were male, white, and older than 1 year. Most patients with WBC count <10,000/mm3 at diagnosis lived. Overall survival was higher in patients with MRD <0.1%. The prognosis was better in patients with AML-M3.


Resumo Objetivo: Descrever o perfil epidemiológico e a taxa de sobrevida dos pacientes com leucemia mielóide aguda (LMA) em um hospital pediátrico de referência estadual. Método: Estudo clínico-epidemiológico, observacional, retrospectivo e descritivo. Foram incluídos casos novos de pacientes com LMA, diagnosticados entre 2004 e 2012, com idade < 15 anos. Resultados: Entre os 51 pacientes estudados, 84% eram da etnia branca, 45% do sexo feminino e 55% do masculino. Quanto à faixa etária, 8% tinham < 1 ano, 47% entre 1 e 10 anos e 45% > 10 anos. Os principais sinais/sintomas ao diagnóstico foram febre (41,1%), astenia/inapetência (35,2%) e manifestações hemorrágicas (27,4%). O sistema nervoso central foi o local extramedular mais acometido (14%). Em 47% dos pacientes a leucometria ao diagnóstico foi < 10.000/mm3. A doença residual mínima (DRM) no 15° dia de tratamento foi < 0,1% em 16% da casuística. Recidiva medular ocorreu em 14% dos casos. Ao se comparar a DRM da medula óssea com o status vital, observou-se que estavam vivos 71,42% dos pacientes com LMA tipo M3 e 54,05% daqueles com LMA não M3. A taxa de óbito foi de 43% e a principal causa imediata foi o choque séptico (63,6%). Conclusões: Neste estudo, a maioria dos pacientes é do sexo masculino, etnia branca, maiores do que um ano. A maioria dos pacientes com leucometria < 10.000/mm3 ao diagnóstico está viva. A sobrevida global é maior nos pacientes com DRM < 0,1%. O prognóstico é melhor nos pacientes com LMA-M3.

ABSTRACT

OBJETIVO: Analisar pacientes com menos de dois anos de idade com leucemia linfoblástica aguda atendidos no período de 1990 a 2010, em um centro de referência estadual. MÉTODOS: Estudo clínico, epidemiológico, transversal, descritivo e observacional. Pacientes incluídos tinham menos de dois anos de idade, com leucemia linfoblástica aguda, tratados no período de 1990 a 2010 na unidade de oncologia pediátrica de um centro de referência estadual, totalizando 41 casos. RESULTADOS: Todos os pacientes eram Caucasianos e 60,9% eram do sexo feminino. Com relação à idade, 24,38% tinham menos de seis meses, 17,07% tinham entre seis meses e um ano e 58,53% mais do que um ano de idade. A idade de seis meses foi estatisticamente significante para o desfecho de óbito. Os sinais e sintomas predominantes foram febre, hematomas e petéquias. Uma contagem de leucócitos superior a 100.000 foi observada em 34,14% dos casos; hemoglobina inferior a 11 em 95,13% e contagem de plaquetas inferior a 100.000, em 75,61% dos casos. Infiltração do sistema nervoso central estava presente em 12,91% dos pacientes. Em relação à linhagem, a linhagem B predominou (73%), mas a linhagem de células T foi estatisticamente significativa para o óbito. Trinta e nove por cento dos pacientes tiveram recorrência da doença. Em relação ao estado vital, 70,73% dos pacientes morreram, sendo choque séptico a principal causa. CONCLUSÕES: leucemia linfoblástica aguda em crianças tem uma alta taxa de mortalidade, principalmente em crianças menores de um ano e linhagem derivada de células T.


OBJECTIVE: To analyze patients younger than 2 years with acute lymphoblastic leukemia, treated in the period between 1990 and 2010 in a state reference center. METHODS: This was a clinical-epidemiological, cross-sectional, observational, and descriptive study. It included patients younger than 2 years with acute lymphoblastic leukemia, treated in the period of 1990 to 2010 in a pediatric oncology unit of a state reference center, totaling 41 cases. RESULTS: All patients were white ethnicity, and 60.9% were females. Regarding age, 24.38% were younger than 6 months, 17.07% were between 6 months and 1 year, and 58.53% were older than 1 year. The age of 6 months was statistically significant for the outcome of death. Predominant signs and symptoms were fever, bruising, and petechiae. A leukocyte count > 100,000 was found in 34.14% of cases, hemoglobin count < 11 in 95.13%, and platelet count < 100,000 in 75.61. Infiltration of central nervous system was present in 12.91% of patients. According to the lineage, B-cell lineage predominated (73%), but the T-cell line was statistically significant for death. 39% of patients had disease recurrence. In relation to vital status, 70.73% of the patients died; septic shock was the main cause. CONCLUSIONS: Acute lymphoblastic leukemia in infants has a high mortality rate, especially in children under 1 year and those with T-cell derived lineage.
