What this trial studies

This study aims to collect and preserve glioblastoma tissue during standard tumor resection surgeries, along with blood samples for molecular and genetic testing. Researchers will gather tissue from three different regions of the tumor to analyze variations in structure, DNA, and RNA. The collected data will be compared with imaging results from medical records to enhance understanding of glioblastoma biology. Ultimately, this research seeks to inform the development of new therapies for glioblastoma treatment.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 and older with high-grade glioma on MRI or those with a confirmed diagnosis of glioblastoma or gliosarcoma undergoing repeat tumor resection.

Not a fit: Patients with medical conditions or therapies that could confound study results or are not in their best interest may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved therapies for glioblastoma patients by enhancing our understanding of tumor biology.

How similar studies have performed: While this approach of specimen banking is common, the specific focus on glioblastoma tissue variation and its correlation with imaging data is a novel aspect that has not been extensively tested.
