However, several studies have suggested that O-(2-(18)F-fluoroethyl)-l-tyrosine ((18)F-FET) PET adds valuable clinical information to the information derived from structural MR imaging alone. We evaluated the effectiveness and cost-effectiveness of the addition of (18)F-FET PET to structural MR imaging for the management of treatment with bevacizumab and irinotecan (BEV/IR) in patients with recurrent high-grade glioma compared with MR imaging alone from the perspective of the German Statutory Health Insurance.To evaluate the incremental cost-effectiveness of the additional use of (18)F-FET PET, a decision tree model was used. Effectiveness of (18)F-FET PET was defined as correct identification of both tumor progression before BEV/IR treatment initiation and BEV/IR treatment response and was evaluated for the combination of (18)F-FET PET and MR imaging compared with MR imaging alone. Costs were estimated for a baseline scenario and for a more expensive scenario. The robustness of the results was tested using deterministic and probabilistic sensitivity analyses.The use of (18)F-FET PET resulted in a number needed to diagnose of 2.4, that is, 3 additional patients have to be diagnosed to avoid 1 wrong diagnosis. The incremental cost-effectiveness ratio of (18)F-FET PET/MR imaging compared with MR imaging alone was €5,725 (€1 ≈ $1.30) for the baseline scenario and €8,145 for the more expensive scenario per additional correct diagnosis. The probabilistic sensitivity analysis confirmed the robustness of the results.The model suggests that the additional use of (18)F-FET PET in the management of patients with recurrent high-grade glioma treated with BEV/IR may be cost-effective. Integration of (18)F-FET PET has the potential to avoid overtreatment and corresponding costs, as well as unnecessary side effects to the patient. %F PUB:(DE-HGF)16 %9 Journal Article %$ pmid:23785172 %U <Go to ISI:>//WOS:000322692400026 %R 10.2967/jnumed.113.120089 %U https://juser.fz-juelich.de/record/137550
