What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
NTRK Fusion	Incidence of NTRK gene fusion identified by RNAseq in glioma and brain metastasis tumour samples.	through study completion, an average of 12 months

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
NTRK Fusion identification in brain metastasis and primary tumor	Incidence of NTRK gene fusion identified in matched pairs of brain metastasis and primary tumor;	through study completion, an average of 12 months
Progression-free survival in patients with NTRK gene fusion	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 6 months	Month 6
Progression-free survival in patients with NTRK gene fusion	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	Month 12
Overall survival in patients with NTRK gene fusion.	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.	through study completion, an average of 12 months
Specific radiological criterion (T1)	Specific radiological criteria (T1) in patients with NTRK gene fusion in gliomas and brain metastases	through study completion, an average of 12 months
Specific radiological criterion (T2)	Specific radiological criteria (T2) in patients with NTRK gene fusion in gliomas and brain metastases	through study completion, an average of 12 months
Specific radiological criterion (FLAIR)	Specific radiological criteria (FLAIR) in patients with NTRK gene fusion in gliomas and brain metastases	through study completion, an average of 12 months
Specific radiological criterion (perfusion)	Specific radiological criteria (perfusion) in patients with NTRK gene fusion in gliomas and brain metastases	through study completion, an average of 12 months
Incidence of other genomic alterations	Incidence of other genomic alterations identified by RNAseq, associated with the incidence of NTRK gene fusion	through study completion, an average of 12 months
