Resumen

La radioterapia de intensidad modulada con bloqueo de mandíbula segmentada (SJL-IMRT) ofrece un enfoque práctico para reducir la irradiación pulmonar en pacientes con cáncer de esófago sometidos a irradiación de ganglios electivos (ENI). Este método optimiza la distribución de la dosis, mejora el ahorro pulmonar y simplifica la planificación del tratamiento en comparación con la IMRT de campo extendido.

Conclusiones:

La SJL-IMRT reduce eficazmente la complejidad del plan y la dosis pulmonar de intermedia a baja para la ENI en el cáncer de esófago torácico superior.
La técnica ofrece una calidad dosimétrica y una simplicidad de entrega mejoradas sin comprometer la cobertura del objetivo.
La SJL-IMRT es un enfoque pragmático que justifica su confirmación en cohortes de pacientes más grandes.
