Summary

FET PET 2010 is a prospective, multicentre trial aiming to evaluate the additional benefit of FET PET in the assessment of remission after first line therapy and during follow-up

Detailed description

2.1 Primary objective The main objective is to evaluate the relative benefit of FET PET in comparison to the MRI in differentiating biologically active tumour tissue from therapy-related changes in paediatric brain tumours after first line therapy (Δ specificityFET PET to specificityMRT) 2.2 Secondary Objectives To assess sensitivity of FET PET in comparison with the sensitivity of MRI (Δ sensitivityFET PET to sensitivityMRT) To assess the positive and negative predictive values (PPV, NPV) of FET PET in comparison with the PPV and NPV of MRI (Δ PPVFET PET to PPVMRT, Δ NPVFET PET to NPVMRT) To evaluate specificity, sensitivity, PPV, and NPV by SUVratio analyses of FET PET data To evaluate the potential of FET PET for non-invasive tumour grading (WHO I/II vs. III/IV) by kinetic studies when histology is available To assess adverse events and toxicity profile 2.3 Endpoints (Standard of truth1) 2.3.1 Primary Endpoint The primary endpoint is an event free survival of the follow-up period of 24 (12) months after first line therapy (confirmed by clinical and neuroradiological assessment) or the confirmed diagnosis of progression or recurrence of brain tumour tissue (confirmed by histology or clinical and neuroradiological assessment). The follow-up period for patients with a low risk of tumour recurrence after first line therapy, i.e. astrocytoma WHO grade I-II, oligodendroglioma WHO grade I-II, germ cell tumour, choroid plexus tumour, craniopharyngioma will be 24 months. The follow-up period for patients with a high risk of tumour recurrence after first line therapy, i.e. astrocytoma WHO grade III-IV, oligodendroglioma WHO grade III-IV, medulloblastoma, supratentorial PNET, AT/RT and other high-grade tumour lesions will be 12 months. 2.3.2 Secondary Endpoints To assess the secondary objectives of the FET PET 2010 study, the investigators will determine event free survival of the follow-up period of 24 (12) months after first line therapy (confirmed by clinical and neuroradiological assessment) or the confirmed diagnosis of progression or recurrence of brain tumour tissue (confirmed by histology or clinical and neuroradiological assessment). Histopathological characteristics of recurrent tumours (WHO grade I-IV) Safety and Toxicity (evolution according to CTCEA v3.0 criteria): the NCI Common Terminology Criteria for Adverse Events v3.0 is a descriptive terminology, that is used for Adverse Event (AE) reporting. A grading scale is provided for each AE term. Attached is a selection of categories, which are required to assess safety and toxicity of FET PET examinations.

Type	Name	Description
DIAGNOSTIC_TEST	FET-PET	All participating patients will receive a FET PET-scan parallel to the routine MRI at the end of the first line therapy (restaging) according to the HIT-protocol Second FET PET: In case of suspected tumour recurrence or progression within the follow-up period of 24 (12) months, the participating patient will receive a second FET PET-scan (parallel to an MRI)
