However, reliable diagnostic criteria regarding therapy monitoring are not established. Here, we analysed the impact of additional 18F-fluoroethyl-tyrosine positron emission tomography (18F-FET PET) imaging following DC vaccination therapy.Methods: We analysed data of GBM patients who received DC vaccination therapy. Following MRI diagnosis of tumour recurrence, additional static and dynamic 18F-FET PET imaging was performed. Vaccination was performed five times by intradermal injections, either weekly between concomitant radio/-chemotherapy and intermittent chemotherapy or after tumour recurrence, before re-radiation therapy. MRI and 18F-FET PET results were compared and correlated with clinical data.Results: Between 2003 and 2016, 5 patients were identified who received DC vaccination and 18F-FET PET imaging (1 female/4 males; mean age: 44 ± 14 y). 3/5 patients showed congruent results of tumour progression. In three patients 18F-FET PET indicated treatment related changes, which was in contrast to MRI findings that indicated tumour progression. In these patients 18F-FET PET results could be confirmed by either neuropathological diagnosis or according to the RANO criteriaConclusions: Despite the small patients number our results indicate an additional impact of 18F-FET PET for monitoring outcome following vaccination therapy.}, cin = {INM-3 / INM-4}, ddc = {610}, cid = {I:(DE-Juel1)INM-3-20090406 / I:(DE-Juel1)INM-4-20090406}, pnm = {5252 - Brain Dysfunction and Plasticity (POF4-525)}, pid = {G:(DE-HGF)POF4-5252}, typ = {PUB:(DE-HGF)16}, pubmed = {31407920}, UT = {WOS:000480905300001}, doi = {10.1080/02688697.2019.1639615}, url = {https://juser.fz-juelich.de/record/864473}, }
