A Dosimetric Comparison of HyperArc Therapy Planning and Volumetric Modulated Arc Therapy Planning in Treating Patients With Glioblastoma Multiforme.

Background/aim: This study aimed at evaluating the potential benefit of automatic non-coplanar volumetric arc therapy (VMAT) (hyperarc, HA) technique in treating glioblastoma multiforme (GBM).

Patients And Methods: Twenty-seven patients with GBM who received coplanar VMAT (C-VMAT) were selected in this study. HA and non-coplanar VMAT (NC-VMAT) plans were generated with the same prescriptions and constraints.
