Simultaneous Integrated Boost in Malignant Glioma Patients Treated With Chemoradiation
Evaluation the Prognostic Significance of High Radiation Dose in Malignant Glioma Patients Treated With Chemoradiation
調査の概要
詳細な説明
The SIB technique provides the higher radiobiological effect with the same fractionation scheme, i.e. 69 Gy over 6 weeks, which might increase the loco-regional control. Besides, the co-registration with magnetic resonance imaging (MRI) strengthens the precision of target delineation as well as higher possibility to spare adjacent normal brain tissue.
In this protocol, the newly diagnosed, primary glioblastoma patients received SIB 69 Gy/30 fractions to preoperative tumor bed and surgical cavity, while 60 Gy/30 fractions were covering preoperatively edematous area. To determine the status of surgical extent, postoperative CT scan and MRI was acquired within 72 hours and at 4th week after surgery. During the period of chemoradiation, acute neurotoxicity and hematological toxicity was assessed as well.

実験的:Simultaneous integrated boost
In this protocol, the newly diagnosed, primary glioblastoma patients receive SIB 69 Gy/30 fractions to preoperative tumor bed and surgical cavity, while 60 Gy/30 fractions were covering preoperatively edematous area.
PTV is 5 mm.
|
Simultaneous integrated boost (SIB), a field-in-field escalation technique, has been introduced to deliver higher radiation dose to the certain part of target with the same fractionation scheme.
