Figure 1

Disease extent for patients having local-regional failures. A, In-field failure. B, Marginal failure. C, Outside-field failure. Left, Pretreatment magnetic resonance imaging (MRI/CT). Middle, The recurrent tumor volumes were transferred from the diagnostic MRI/CT at the time of recurrence to the planning computed tomography to show doses delivered to the recurrence sites. Right, MRI/CT at time of failure. IMRT = intensity-modulated radiotherapy.
