|Condition or disease||Intervention/treatment||Phase|
|Adult Giant Cell Glioblastoma Adult Glioblastoma Adult Gliosarcoma Recurrent Adult Brain Tumor||Drug: aminolevulinic acid Procedure: therapeutic conventional surgery||Phase 2|
I. Determine the volume of residual enhancing tumor after a 5-ALA guided resection of a glioblastoma multiforme (GBM).
II. Determine the volume of tissue removed compared to the measured enhancing tumor evaluated on a pre-operative MRI.
I. Evaluate the time to tumor progression. II. Evaluate the overall survival.
Patients receive aminolevulinic acid orally (PO) 2-4 hours before surgery.
After completion of study treatment, patients are followed up for 2 weeks.

Experimental: Diagnostic (aminolevulinic acid)
Patients receive aminolevulinic acid PO 2-4 hours before surgery.
Drug: aminolevulinic acid
Other Names:Procedure: therapeutic conventional surgery
- Volume of residual enhancing tumor, as determined by intraoperative volume MRI without and with gadolinium, following maximal resection with use of aminolevulinic acid [ Time Frame: Day 1 ]Volume of enhancing tumor (initial and residual) will be determined by use of a softwarebased volumetric analysis method. Intra- and post-op definitions of residual tumor volume need to be adjusted for the presence of T1 hyperintensity due to signal from blood and blood products (as determined on pre-gadolinium volume study).
- Comparison between the volume of resected tissue (defined as the volume of the resection cavity) and the pre-operative enhancing tumor volume [ Time Frame: Up to day 1 ]Volume of enhancing tumor (initial and residual) will be determined by use of a software-based volumetric analysis method. Intra- and post-op definitions of residual tumor volume need to be adjusted for the presence of T1 hyperintensity due to signal from blood and blood products (as determined on pre-gadolinium volume study).
- Time to disease progression (TTP), determined by review of MRIs performed post operatively as clinically indicated, evaluated with use of the new international criteria proposed by the Response in NeuroOncology (RANO) Committee [ Time Frame: From the date of surgery with aminolevulinic acid to the date of progression, assessed up to 1 year ]
- Overall survival, by periodic follow up review of the patient charts and by correlation with the Social Security Death Index [ Time Frame: From the date of surgery with aminolevulinic acid to the date of death, assessed up to 1 year ]
