Introducción: La leucemia linfoblástica aguda del adulto en América Latina plantea desafíos clínicos y epidemiológicos, agravados por la disponibilidad de datos en la región.
Objetivo: Evaluar la supervivencia global a 5 años y la supervivencia libre de recaída en pacientes tratados con quimioterapia intensiva, caracterizar de manera sistemática las complicaciones relacionadas con el tratamiento, identificar factores pronósticos asociados con los desenlaces clínicos y describir los perfiles clínicos y demográficos de la población estudiada.
Métodos: Estudio observacional retrospectivo en 127 pacientes adultos diagnosticados con LLA, tratados con quimioterapia intensiva. Se analizaron sistemáticamente variables demográficas, clínicas, citogenéticas, entre otras, así como los desenlaces de supervivencia.
Resultados: 63,7% de los pacientes tenía menos de 40 años. La tasa de remisión completa tras la terapia de inducción fue del 58,5%. La mortalidad relacionada con la inducción alcanzó el 26,7%, atribuible a sepsis por Klebsiella pneumoniae productora de carbapenemasas, responsable del 67,4% de las muertes durante la inducción. La infección por K. pneumoniae productora de carbapenemasas , el aumento de la edad y el tratamiento con esquemas basados en L-asparaginasa emergieron como predictores independientes de mortalidad relacionada con la inducción. La supervivencia global estimada a cinco años fue del 17%, solo el 4% fue sometido a trasplante alogénico de células madre hematopoyéticas.
Discusión: La LLA del adulto se caracterizó por una elevada mortalidad relacionada con la inducción, impulsada principalmente por infecciones bacterianas multirresistentes, junto con un acceso severamente limitado al trasplante alogénico.
Conclusiones: hallazgos subrayan la necesidad urgente de implementar políticas de salud integrales orientadas a mejorar los resultados clínicos en esta población de pacientes.
