  Late radiation dose complications in patients with head and neck cancer treated with IMRT or VMAT represent a major problem; some of these complications came from the dose to organs that exceed their tolerance. In our study, patients underwent a new CT after ten and twenty treatment sessions and the initial plan then projected on the new CTs and the plans were called (hybrid plans). In hybrid plans, the dose for all organs was increased compared to initial plan (iplan) and in some cases the dose for organs was greater than their tolerance. The median maximum dose for spinal cord at iplan was 4113 [3967-4254] cGy and significantly increased (p<0.001) at Hplan1 to reach 4390[4154-4587] cGy and significantly increased again (p<0.001) at Hplan2. Also, the median maximum dose for brainstem at iplan was 5156[4561-5324] cGy then significantly increased (p<0.001) to 5321[4688-5545] c.. Read More»
