چکیده

UNLABELLED High-grade gliomas are brain tumors associated with a devastating prognosis. Recent studies have indicated that the combined use of amino acid PET and MRI is superior to MRI alone to plan the surgical resection of high-grade gliomas. The aim of the study was to analyze the cost-effectiveness of the use of amino acid PET for the surgical resection of high-grade gliomas, compared with MRI alone, from the perspective of the national health insurance in Germany. METHODS A decision-tree model was set up to compare 2 strategies: the use of MRI alone and the combined use of MRI and PET for surgical resection of high-grade gliomas. For the analysis, 2 scenarios were calculated: a baseline scenario and a more expensive scenario, accounting for disease severity. To test the robustness of the results, probabilistic sensitivity analyses using Monte Carlo simulation were calculated. RESULTS Compared with MRI alone, the combined use of MRI and PET showed an incremental cost-effectiveness ratio of €2,948 (€1 ~ U.S.$1.3)per life-year gained for the baseline scenario and an incremental cost-effectiveness ratio of €4,105 per life-year gained for the admissible-charge-rate scenario. In the probabilistic sensitivity analysis in about 60% of the iterations, the combined use of PET and MRI was superior to MRI alone when assuming a willingness-to-pay threshold of €30,000. CONCLUSION The model indicates that the combined use of MRI and PET may be cost-effective. The results of this analysis have to be considered carefully because there was only limited empiric evidence for several input parameters.

A Pilot Cost-Effectiveness Analysis of Treatments in Newly Diagnosed High-Grade Gliomas: The Example of 5-Aminolevulinic Acid Compared With White-Light Surgery

BACKGROUND High-grade gliomas are aggressive, incurable tumors characterized by extensive diffuse invasion of the normal brain parenchyma. Novel therapies at best prolong survival; their costs are formidable and benefit is marginal. Economic restrictions thus require knowledge of the cost-effectiveness of treatments. Here, we show the cost-effectiveness of enhanced resections in malignant gliom...

OBJECTIVE Integrating positron emission tomographic (PET) images into the image-guided resection of high-grade gliomas (HGG) has shown that metabolic information on tumor heterogeneity and distribution are useful for planning surgery, improve tumor delineation, and provide a final target contour different from that obtained with magnetic resonance imaging (MRI) alone in about 80% of the procedu...

Application of 5-ALA Fluorescence-Guided Resection in Patients Suffering from High-Grade Gliomas: Report of 30 Consecutive Cases and a Literature Review

Background and Importance: The extent of resection seems a solid prognostic factor in patients suffering from high-grade gliomas (HGGs). When administered orally, 5-ALA is exclusively converted by malignant cells into protoporphyrin IX (PPIX), identifying contrast-enhancing glial lesions under blue 400-nm light. The authors thoroughly assess the efficacy, accuracy, and safety profile of 5-ALA-g...

Comparison of Prooxidant-antioxidant Balance between Patients with High Grade Gliomas (IV) and Control Group

Background & Aim: The most common primary brain tumors of the central nervous system are gliomas. Among a number of different biomolecular events, a strong relation between oxidative stress pathways and the development of this cancer has been proved. Oxidative stress (OS) is the consequence of an imbalance between pro-oxidants and antioxidants towards pro-oxidants. The pro-oxidants cause lipid ...
