Resumen
Objetivo: Analizar la tendencia de la incidencia y mortalidad de leucemias y linfomas infantiles, así como estimar la supervivencia utilizando la razón mortalidad/incidencia en Mato Grosso. Métodos: Se analizaron los datos del registro de cáncer de base poblacional de Mato Grosso de 2001 a 2017, así como los datos de mortalidad de 2001 a 2021 extraídos del Sistema de Información de Mortalidad. El análisis consistió en frecuencias, tasas de incidencia ajustadas (AIR) por millón y resultados de regresión joinpoint. Las estimaciones de supervivencia se calcularon utilizando la relación entre el número de muertes y casos incidentes [1-(M:I)] de 2013 a 2017. Resultados: Las leucemias representaron el 67,7% de los casos con una tasa de incidencia de 29,9 y 13,9 para los linfomas, mientras que la tasa de mortalidad fue de 18,0. Hubo una tendencia significativa a la baja en la incidencia de leucemias en ambos sexos -4,0% y en mujeres -5,5%, mientras que la incidencia de linfomas y la mortalidad se mantuvieron estables. Las estimaciones de supervivencia fueron del 88% y el 74% para las leucemias y los linfomas. Conclusión: Las tasas de incidencia y mortalidad y las estimaciones de supervivencia fueron intermedias para los contextos epidemiológicos de los países de ingresos altos y medios, con una reducción significativa de la incidencia de leucemias.
