Evolución de la leucemia linfoblástica aguda en la edad pediátrica en 29 años ( )Outcome of acute lymphoblastic leukemia in the pediatric age group . La leucemia linfoblástica aguda (LLA) es el cáncer más común en los niños y está entre los más curables de las malignidades pediátricas. El análisis citogenético de las células blásticas en niños con leucemia linfoblástica aguda (LLA) ha permitido el reconocimiento de alteraciones cromosómicas.
