  Background: Sequential intensity modulated radiotherapy(IMRT) has been widely used in clinic.Usually there are two approaches,including composite and synchronous planning approaches,to be introduced to design sequential IMRT plan.The purpose of present study was to compare the dosimetric differences of the radiotherapeutic plans between synchronous and composite planning approaches in sequential IMRT for nasopharyngeal carcinoma(NPC).
