NCT01801371
This is an open-label brain PET/CT (positron emission tomography/computed tomography) study to investigate the diagnostic performance and evaluation efficacy of 68Ga-BNOTA-PRGD2 in glioma patients. A single dose of nearly 111 MBq 68Ga-BNOTA-PRGD2 (≤40 µg BNOTA-PRGD2) will be intravenously injected into patients in suspicion of glioma. Visual and semiquantitative method will be used to assess the PET/CT images. Brain MRI with/without enhancement and 18F-FDG PET/CT will be performed for comparison. The postoperative pathology and integrin αvβ3 and CD34 immunohistochemical stains will also be used for correlation.
NCT02520882
This is an open-label positron emission tomography/computed tomography (PET/CT) study to investigate the diagnostic performance and evaluation efficacy of 68Ga-NOTA-Aca-BBN(7-14) in glioma patients. A single dose of 111-148 Mega-Becquerel (MBq) 68Ga-NOTA-Aca-BBN(7-14) will be injected intravenously. Visual and semiquantitative method will be used to assess the PET/CT images.
NCT02607397
The cost of particle therapy (PT) are considerably higher than conventional radiotherapy (RT) with photons. Considering potential dosimetric advantages of PT, it is necessary to determine if PT are more cost-effective than photons per indication regarding quality of life, survival, and progression free survival. Given the lack of evidence for the benefit of particle therapy in relevant cases, investigators proposed an in silico trial to investigate to what extend proton therapy decrease the amount of irradiated normal tissue and, consequently, the risk of side effects in the surrounding normal tissue as well as the risk of secondary tumors. Given validated dose-response curves and/or NTCP models, a 10% lower mean dose of proton therapy on normal tissue compared to photon therapy should result in at least a 20% lower risk of side effects.
