Three different types of recurrent patterns of NPC treated with IMRT. a in field failure; b marginal failure; c outside field failure. Left, pretreatment magnetic resonance imaging (MRI); Middle, the recurrent tumor was transferred from the MRI at the time of recurrence to the planning computed tomography (CT) to present doses to the recurrent sites; Right, MRI at the time of recurrence. The green line represented the initial gross target volume; The pink line represented the recurrent tumor volume; The red color-wash represented 70Ā Gy, yellow represented 66Ā Gy, and blue represented 60Ā Gy
