Background: Acute lymphoblastic leukemia is the most common cancer in children. In developed countries, overall survival rates are around 80%, while in developing countries, survival rate is much lower due to high rates of relapse, and abandonment and complications arising from the disease treatment. Objectives: To assess induction mortality, relapse and treatment abandonment. To describe the most frequent side effects of chemotherapy. To evaluate survival rates of patients and compare the findings found in this study with the existing literature. Material and methods: A retrospective cohort study was conducted on patients aged 1 to 18 with acute lymphoblastic leukemia, who received treatment under the BFM ALL IC 2009 protocol at Fundación Hospital La Misericordia (HOMI), from November 2012 to December 2014. Results: 119 patients were included. Death occurred in two cases during induction (1.67%) and in nine (7.7%) due to treatment, all of them caused by infection/sepsis and in complete remission. Six patients abandoned treatment (5%), while seven relapses occurred (5.9%). All patients experienced some type of side effect related to chemotherapy, the most frequent being febrile neutropenia (41.2%) and grade 3-4 infections (15.8%). Overall survival and event-free survival rates were 79.9% and 73.3%, respectively. Conclusions: Evaluating complications of treatment and death allows adopting measures and strategies to reduce such complications.

RESUMEN Introducción: la leucemia aguda es la neoplasia más común en niños, constituye aproximadamente el 25 % de todos los tumores en la infancia. En Colombia la proporción de curación, alrededor del 50 %, es inferior a lo informado en países desarrollados. Objetivo: el objetivo principal es determinar la supervivencia global y libre de eventos, la proporción de abandono y recaída de los niños con el diagnóstico de leucemia linfoide aguda tratados con el Protocolo ACHOP 2006. Materiales y métodos: estudio descriptivo de tipo cohorte de 183 pacientes menores de 18 años, con el diagnóstico confirmado de leucemia linfoide aguda, que recibieron tratamiento en la Fundación HOMI desde el 2007 hasta el 2012. Los análisis de supervivencia se obtuvieron con curvas de Kaplan-Meier. Resultados: se analizó la supervivencia global a 2, 3 y 5 años con resultados de 89 %, 87,3 % y 74,7 % (IC 95 % 67-80,9), respectivamente. A los 5 años la supervivencia para el grupo de riesgo estándar fue de 78,6 % (IC 95 % 68,3 - 85,1) y para el de riesgo alto 61,9 % (IC 95 % 50,7- 73). La supervivencia libre de evento, al considerar el abandono y traslado a otra institución como evento, fue de 56,3 % (IC 95 % 45,5-65,8) a los 5 años. La mortalidad en inducción fue de 3,8 %, la mortalidad relacionada con el tratamiento fue 3,4 %. Treinta y dos pacientes (17 %) recayeron, el abandono fue de 16,4 % y los traslados de 10,4 %. La principal complicación del tratamiento fueron las infecciones. Conclusiones: la supervivencia global es aceptable para un país de recursos limitados. Los eventos de abandono y traslado son muy altos. Deben aunarse esfuerzos para disminuir estas situaciones que empeoran el pronóstico de la enfermedad. SUMMARY Introduction: Acute leukemia is the most common neoplasm in children, accounting for approximately 25% of all tumors in childhood. In Colombia the cure proportion, around 50%, are lower than reported in developed countries. Objective: The main objective is to determine the global and event-free survival of children with diagnosis of lymphoblastic leukemia, all treated with the ACHOP Protocol 2006, from 2007 to 2012. The secondary objectives are to describe mortality, abandonment, relapse and major complications related to treatment. Material and methods: A descriptive cohort study of 183 patients under 18 years of age, with a confirmed diagnosis of acute lymphoblastic leukemia, who were treated at the Foundation of the Misericordia (HOMI) from 2007 to 2012, was performed. The survival dates were obtained by analysis with Kaplan-Meier curves. Results: We analyzed overall survival at 2, 3 and 5 years with results of 89%, 87.3% and 74.7 % (95% CI 67 - 80.9) respectively. At 5 years survival for the standard risk group was 78.6 % (95 % CI 68.3-85.1) and 61.9 % (95 % CI 50.7-73) for the high risk group. The event-free survival, considering the abandonment and transfer to another institution as an event, was 56.3 % (95% CI 45.5 - 65.8) at 5 years. Mortality in induction was 3.8 %, mortality related to treatment was 3.4 %, 32 patients (17 %) relapsed, abandonment was 16.4 % and transfers 10.4 %. The main complication of the treatment was infections. Conclusions: Overall survival is acceptable for a country with limited resources, the events of abandonment and transfers are very high. Efforts should be made to reduce these situations that worsen the prognosis of the disease.
