Introducción: Para evaluar la calidad de los planes de tratamiento de radioterapia es conveniente analizar no solo la distribución de dosis calculada, sino también su complejidad. En este estudio se describen herramientas para calcular métricas de complejidad y se muestra su utilidad comparando planes optimizados con y sin control de complejidad.
Material y métodos: Se optimizaron planes con y sin control de complejidad usando la herramienta Aperture Shape Controller del sistema de planificación Eclipse y el control del número de Unidades de Monitor en dos casos clínicos. La comparación dosimétrica se realizó mediante análisis de planos axiales, perfiles de dosis e índices dosimétricos. La complejidad se cuantificó usando métricas calculadas con dos herramientas de desarrollo propio (script de Eclipse y PlanAnalyzer, programado en MATLAB).
Resultados: Al usar las herramientas de control de complejidad se obtuvieron planes con grados de complejidad mucho menores en los dos casos evaluados, pero manteniendo distribuciones dosimétricas muy similares y resultando todos clínicamente aceptables.
Conclusiones: El control y análisis de la complejidad son importantes en la evaluación de los planes de tratamiento. Las herramientas utilizadas para evaluar la complejidad se ponen a disposición de los socios de la Sociedad Española de Física Médica.
