A reirradiation workflow for managing patients with treatments planned in a multi-TPS environment.

Reirradiation is becoming more common. Safe and effective implementation relies on accurate dose accumulation methodology, complex treatment planning, and multidisciplinary communication. Clinical workflow guidance to address these challenges is needed. Herein we report a TPS-agnostic reirradiation workflow, developed at our institution, that facilitates comprehensive cumulative dose evaluation and can improve safety and efficiency in reirradiation programs.
