About

This is an exploratory, translational and non-interventional clinical study. The aim of this study is to identify a blood biomarker signature for glioma.

Full description

The identification of biomarkers (proteins, peptides and micro RNAs (miRNAs)) in the serum of patients with glioma would be a new, less invasive approach, which could help in the diagnosis of a glioma, and potentially help guide therapeutic decisions.

The investigators will investigate the existence of biomarker profiles, which can

• distinguish between low and high grade gliomas
• correlate with patient outcomes including response to treatment and survival
• indicate progression from a low to a high grade glioma.

In this study the investigators collect and analyse blood samples taken from patients with suspected newly diagnosed grade II/III glioma or glioblastoma multiforme (GBM). Blood samples will be collected before any surgical intervention (resection or biopsy) and at various follow-up time points until progression or death. Based on the known natural history of gliomas (described above), it is planned to follow patients with grade III/IV tumours, who receive treatment, for up to 3 years and those with grade II-III tumours, (irrespective of treatment) for up to 5 years. Ultimately, the investigators envisage the translation of our observations into the hospital setting to aid the distinction between glioma grade II and grade III/IV.
