Comparison of outcomes between overlapping structure-based and non-overlapping structure-based optimization for simultaneous integrated boost IMRT for malignant gliomas

Abstract

The two optimization methods provided comparable dose distributions within the target volumes and normal brain.

Treatment outcomes and dose-volume histogram analysis of simultaneous integrated boost method for malignant gliomas using intensity-modulated radiotherapy

“…We have already reported the details of the target volume delineation in this clinical trial, in which the contouring of PTV-G and PTV-a was graphically demonstrated. 6,12 Treatment planning A commercial treatment-planning system (Cadplan Helios ver.6.01; Varian Associates, Palo Alto, CA, USA) was used. The IMRT beam arrangements consisted of fi ve coplanar beams.…”
