Clinical Dosimetric Comparison among Different Intensity-Modulated Radiotherapy Plans for Nasopharyngeal Carcinoma

Objective:To compare the dosimetric differences of different intensity-modulated radiation therapy (IMRT) plans for nasopharyngeal carcinoma (NPC). Methods: 5-, 7- and 9-ifelds of IMRT plans in 16 NPC patients were respectively designed and synchronous dimention technology was applied to compare the...

Zusammenfassung:Objective:To compare the dosimetric differences of different intensity-modulated radiation therapy (IMRT) plans for nasopharyngeal carcinoma (NPC). Methods: 5-, 7- and 9-ifelds of IMRT plans in 16 NPC patients were respectively designed and synchronous dimention technology was applied to compare the dosimetric differences in target areas and involved organs. Results:The recovery rate in target area was 95% while the plan was evidently worse in 5-ifeld than in 7- and 9-ifelds (P0.05), which were obviously lower in 5-ifeld, and the differences were both signiifcant (P
