Quality and dosimetric assessment of treatment plan of three-dimensional conformal radiotherapy versus intensity-modulated radiotherapy in high-grade gliomas – A prospective study

Background: High-grade gliomas (HGG) are aggressive central nervous system tumors with a poor prognosis. Techniques such as intensity-modulated radiotherapy (IMRT) aim to improve dose conformity and spare normal tissues compared to three-dimensional conformal radiotherapy (3DCRT). Aims and Objectives: The aim is to assess the dosimetry and treatment quality of 3DCRT versus IMRT in HGG. Materials and Methods: In this prospective study, 30 patients were allocated to 3DCRT (n=15) or IMRT (n=15). Bo
