About this trial

Glioblastomas are the most frequent and aggressive malignant tumors of the CNS in adults, with almost systematic relapse despite treatment with surgery followed by radio-chemotherapy (STUPP protocol). The aim of this study is to better characterize transcriptomic, proteomic and metabolic changes in relapsed glioblastoma compared to the initial tumor, in order to identify new prognostic markers and potential new therapeutic targets.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

age > 18 years

Trial population

Patients with relapsed glioblastomas reoperated at the University Hospital of Bordeaux, France, between 2005 and 2023, for which tumor material is available

Trial outcomes

Primary outcomes

1

Evaluation of metabolic changes involved in glioblastoma relapse

Relative abondance of metabolite and differential enzyme expression in a recurrence versus primary sample

Time frame

Secondary outcomes

1

Progression-free survival

Time frame
From date of the second surgery until the date of first documented progression or date of death from any cause, whichever came first, assessed up to 5 years
2

Overall survival

Overall survival of patients who underwent surgery for relapse glioblastoma after the surgery of relapse

Time frame
From date of the second surgery until the date of death from any cause, assessed up to 5 years
