Brief Summary

This is a retrospective, mono centric, exploratory study to assess the incidence of a genomic alteration: NTRK gene fusion, in adult gliomas and brain metastases.

Detailed Description

Retrospective mono centric study of medical data (clinical, histological, molecular and imaging) from medical records and analysis of available excisional tissue samples.

Primary Outcome Measures
NameTimeMethod
NTRK Fusionthrough study completion, an average of 12 months

Incidence of NTRK gene fusion identified by RNAseq in glioma and brain metastasis tumour samples.

Secondary Outcome Measures
NameTimeMethod
Progression-free survival in patients with NTRK gene fusionMonth 12

Progression-free survival in patients with NTRK gene fusion. Progression-free survival is defined as the time from the date of initial surgery to the date of diagnosis of progression. Progression will be defined according to the RANO criteria at 12 months

Overall survival in patients with NTRK gene fusion.through study completion, an average of 12 months

Overall survival in patients with NTRK gene fusion. Overall survival is defined as the time from the date of initial surgery to the date of death (or the date of last news) of the patient.
