abstract = {AbstractAntiangiogenic treatment using bevacizumab in brain
tumor patients may cause difficulties in the diagnosis of
tumor progression (ie, nonenhancing tumor progression).
Newly defined criteria for treatment assessment and
diagnosis of tumor progression (ie, RANO [Response
Assessment in Neuro-Oncology] criteria) have implemented
signal alterations on T2/fluid-attenuated inversion recovery
(FLAIR) sequences to changes in contrast enhancement.
However, T2/FLAIR hyperintensity may be influenced by other
causes (eg, radiation-induced leukoencephalopathy,
peritumoral edema, gliosis). Positron emission tomography
using the radiolabeled amino acid
O-(2-[18F]fluoroethyl)-l-tyrosine (18F-FET-PET) may help
detect the metabolically active tumor extent. We present
18F-FET-PET imaging findings in a glioblastoma patient
during bevacizumab treatment suggesting an earlier diagnosis
of tumor progression than magnetic resonance imaging
changes, which are based on the RANO criteria.},
