Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The present study aims to generate detailed molecular characterization of paired tumor samples (i.e. obtained at first operation and at the time of tumor recurrence) of patients with glioma, with specific interest for at least 100 well-annotated patients with IDH-mutant (1p/19q non-codeleted) astrocytomas. Molecular data will be correlated to clinical and imaging data of these patients to identify molecular and/or imaging markers indicative for early malignant progression. | — |
Secondary
| Measure | Time frame |
|---|---|
| To identify molecular alterations in the recurrent tumors that occur under pressure of different therapeutic modalities. To identify new targets for further therapeutic interference. | — |
