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.

Cytogenetic analysis of lehcemia cells in childhood acute lymphoblastic leukemia has led to the recognition of specific non-random chromosomal abnormalities with prognostic value.

Most patients with ALL show karyotype abnormalities, either in chromosome number ploidy or as structural changes such as translocations, inversions, or deletions. Many of these chromosomal alterations are associated with specific cytomorphological and immunological types.

The greatest impact on patient management has been the finding that the cytogenetic result is an independent prognostic indicator. Certain karyotypes are associated with a favorable prognosis while others indicate a poor outcome. This has led to the administration of alternative therapies according to risk.
