Abstract
Background: The aim of the present study was to compare intensity-modulated radiation therapy (IMRT) plan with Bone Marrow sparing (BM-IMRT) and plan without Bone Marrow Sparing (N-IMRT). Materials and Methods: Fifteen cases of cervical cancer cases were selected for retrospective analysis. All the cases were previously treated with normal IMRT. For this study, plans with BM-IMRT were created again for all patients following Radiation Therapy Oncology Group (RTOG) guidelines. The prescribed dose (PD) of 50Gy in 25 fractions was given. The plan having coverage of 95% of PTV receiving 95% of prescribed dose was accepted. The plans were compared on the basis of planning target volume (PTV) coverage (dose to 2%, 98% of target), Constraints of OAR (Organs at Risk) were volume of 40% < 40Gy for normal bladder and rectum, (volume receiving dose 5Gy) V5
