RESUMEN

En la actualidad existen muchas herramientas de imagen para diagnóstico en cirugía oncológica, la más reciente es la tomografía por emisión de positrones fusionada con tomografía computarizada multicorte (PET CT). Hoy por hoy no existe evidencia sobre las ventajas de esta prueba diagnóstica en oncología pediátrica a pesar de que hoy en día sus aplicaciones van en aumento. De todos los tipos de cáncer, en los cuales el PET CT ha sido usado, sólo dos son vistos en la edad pediátrica, el resto de la patología oncológica de los adultos es inusual en esta población. De tal manera que las revisiones hechas con fines estadísticos del PET CT en pacientes oncológicos adultos, no son válidas en pediatría. Se realizó un estudio retrospectivo, descriptivo de pacientes oncológicos pediátricos a quienes se les practicó PET CT. El propósito del estudio fue: 1) Estatificación del tumor previo al inicio de quimioterapia y/o cirugía, 2) Búsqueda de tumor residual, al terminar quimioterapia adyuvante, neoadyuvante, o para etapas metastásicas, 3) Para seguimiento: con la intención de documentar datos de reactivación tumoral, durante la fase de vigilancia de los pacientes ya tratados, y 4) Diagnóstico diferencial de patología tumoral benigna y maligna.
