| مستخلص: | Introduction: In the United States, between 4 and 8% of children with acute myeloid leukemia have acute promyelocytic leukemia (APL), but a higher incidence of this malignancy has been reported in Latin America (20%-28%). The implementation of the PETHEMA LPA 99 protocol, designed for the treatment of APL in adults, has shown an overall survival (OS) >80%. Objective: To describe the results obtained after the implementation of the PETHEMA LPA 99 protocol to treat children with APL at the Fundación Hospital Pediátrico La Misericordia in Bogotá, D.C., Colombia. Materials and methods: Descriptive and retrospective cohort study. The medical records of 30 pediatric patients (<18 years) with APL, who were treated using the PETHEMA LPA 99 protocol between January 2005 and December 2012, were reviewed. Data on the following variables were obtained: early death, death during induction therapy, OS, event-free survival (EFS), and relapse. Results: The male sex was predominant (60%) among the 30 patients included in the study. Regarding risk classification, 13 (43%) were classified as high-risk patients, 12 (40%) as medium-risk, and 5 (17%) as low-risk. Seven individuals died: 2 before receiving cancer treatment, 2 during induction therapy, and 3 after relapse. Relapse was reported in 5 patients. There were no deaths during the consolidation or maintenance phases. OS was 75.4% (95%CI: 55.1-87.5) and EFS was 64.3% (95%CI: 40-80.5). Moreover, OS at 11 years was 80%, 91.7%, and 59.2% for low-risk, intermediate-risk, and high-risk patients, respectively. The median follow-up time was 6.35 years (0-11.43 years). Conclusions: In general, the implementation of the PETHEMA LPA 99 protocol to treat APL in the study population showed very satisfactory results. Therefore, its use in pediatric population is recommended, taking into account the adjustments described in the protocol regarding the characteristics of this age group. Introducción. En Estados Unidos de América, entre 4 y 8% de niños con leucemias mieloides agudas tienen leucemia promielocítica aguda (LPA), mientras que en Latinoamérica se ha descrito una mayor incidencia de esta neoplasia (20-28%). La implementación del protocolo PETHEMA LPA 99, diseñado para el tratamiento de LPA en adultos, ha mostrado una supervivencia global (SG) >80%. Objetivo. Describir los resultados de la aplicación del protocolo PETHEMA LPA 99 en el tratamiento de niños con LPA en la Fundación Hospital Pediátrico la Misericordia, en Bogotá D.C., Colombia. Materiales y métodos. Estudio de cohorte descriptivo y retrospectivo. Se revisaron las historias clínicas de 30 pacientes pediátricos (<18 años) con LPA que recibieron tratamiento mediante el protocolo PETHEMA LPA 99 entre enero de 2005 y diciembre de 2012. Se obtuvieron datos sobre las siguientes variables: muerte temprana, muerte en terapia de inducción, SG, supervivencia libre de evento (SLE) y recaída. Resultados. De los 30 pacientes, la mayoría eran de sexo masculino (60%). Respecto a la clasificación de riesgo, 13 (43%) fueron clasificados como pacientes de riesgo alto; 12 (40%), de riesgo intermedio, y 5 (17%), de riesgo bajo. 7 individuos murieron: 2 antes del tratamiento oncológico, 2 durante la terapia de inducción y 3 luego de presentar recaída. Se reportó recaída en 5 pacientes. No hubo muertes durante las fases de consolidación o de mantenimiento. La SG fue de 75.4% (IC95%: 55.1-87.5) y la SLE fue de 64.3% (IC95%: 40-80.5). La SG a 11 años fue de 80%, 91.7% y 59.2% para los pacientes de riesgo bajo, riesgo intermedio y riesgo alto, respectivamente. La mediana de seguimiento fue 6.35 años (0-11.43 años). Conclusiones. En general, la implementación del protocolo PETHEMA LPA 99 en el tratamiento de la LPA en la población de estudio mostró resultados muy satisfactorios, por lo que se recomienda su uso en población pediátrica, teniendo en cuenta los ajustes recomendados por el protocolo en |
