Purpose: Early detection of treatment response in glioma patients after radiochemotherapy (RCX) is uncertain because treatment-related contrast enhancement in magnetic resonance imaging can mimic tumor progression. Positron emission tomography (PET) using the amino acid tracer [(18)F]fluoroethyltyrosine (FET) seems to be a promising tool for treatment monitoring. The aim of this prospective study was to evaluate the prognostic value of early changes of FET uptake after postoperative RCX in glioblastomas. Methods and Materials: Twenty-two patients with glioblastoma were treated by surgery and subsequent RCX (whole dose 60-72 Gy). The FET-PET studies were performed before RCX, 7-10 days and 6-8 weeks after completion of RCX. Early treatment response in PET was defined as a decrease of the maximal tumor-to-brain ratio (TBR(max)) of FET uptake after RCX of more than 10%. The prognostic value of early changes of FET uptake after RCX was evaluated using Kaplan-Maier estimates for median disease-free survival and overall survival. Results: The median overall and disease-free survival of the patients was 14.8 and 7.8 months. There were 16 early responders in FET-PET (72.7%) and 6 nonresponders (27.3%). Early PET responders had a significantly longer median disease-free survival (10.3 vs. 5.8 months; p < 0.01) and overall survival (not reached vs. 9.3 months; p < 0.001). No statistically significant differences between the patient subgroups were found concerning the defined prognostic parameters. Conclusions: FET-PET is a sensitive tool to predict treatment response in patients with glioblastomas at an early stage after RCX. (C) 2011 Elsevier Inc.

Summary: The retrospective analysis evaluated the diagnostic value of consecutive PWI and [F-18]FET PET, showing that the combination of both methods can improve overall accuracy. Under specific conditions, PWI outperformed [F-18]FET PET for certain tumors. These results emphasize the importance of sequential use of PWI and [F-18]FET PET in clinical diagnosis.

Finding New Communities: A Principle of Neuronal Network Reorganization in Alzheimer's Disease

Summary: The study revealed a reorganization of functional connectome communities in Alzheimer's disease patients, resulting in lower overall efficiency and higher tau pathology burden in nodes tending to leave communities. This suggests a correlation between local tau pathology in AD and fundamental changes in basic organizational principles of the human connectome.

Summary: Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease with neuroinflammation playing a key role in its pathogenesis. A treatment study using RD2RD2 in a transgenic mouse model of ALS showed reduction of astrocytes and microglia activation, rescue of neurons, and slowed disease progression, making RD2RD2 a potential therapeutic candidate against ALS.

Differential neural structures, intrinsic functional connectivity, and episodic memory in subjective cognitive decline and healthy controls

Summary: In individuals with subjective cognitive decline (SCD), memory complaints are associated with sub-clinical depression and executive functions rather than memory performance. Additionally, memory complaints in SCD are correlated with higher gray matter density in specific brain regions. The study did not find evidence of early neurodegeneration in SCD, but identified sub-clinical depression as a potential underlying factor for subjective cognitive complaints.

Summary: This study used structural MRI and amino acid PET in conjunction with brain atlases and elastic registration techniques to investigate the impact of treatment-related brain damage on cognitive functioning in well-functioning WHO Grade III/IV glioma patients. The results showed that T2/FLAIR hyperintensities caused by radiation therapy significantly impaired cognitive performance, especially affecting the left hemisphere functional nodes and fiber tracts, which were highly correlated with verbal episodic memory dysfunction.

Hybrid PET/MRI in Cerebral Glioma: Current Status and Perspectives

Summary: Advanced MRI methods and PET using radiolabelled amino acids provide valuable additional information for brain tumour diagnostics. While the hybrid PET/MRI has allowed for the convergence of these methods, simultaneous imaging has limited relevance in clinical neuro-oncology. A multimodal approach that combines PET and MRI shows promising improvement in the diagnosis of cerebral gliomas.

Summary: Changes in F-18-FET PET parameters were found to be helpful for early identification of responders to adjuvant TMZ therapy, predicting prolonged progression-free survival (PFS) and overall survival (OS). These changes were independent of other strong prognostic factors, suggesting their potential clinical utility in glioma patients.

Summary: A linearized model for dynamic PET scans of F-18-FET TACs was derived and validated in this study, showing high agreement with measured TACs and small parameter uncertainties. The model demonstrated good diagnostic performance in discriminating between IDH wildtype and IDH mutant gliomas in adult patients. Voxel-wise fitting within a short computation time and comparable classification accuracy to linear fits based on average TAC values were achievable.
