What this trial studies

This clinical trial evaluates the safety and efficacy of neoadjuvant radiochemotherapy in patients with glioblastoma prior to surgical resection. Participants will undergo stereotactic biopsy, followed by conformal hypofractionated stereotactic radiotherapy combined with temozolomide, and then a guided surgical resection. The study aims to assess safety outcomes such as neurological deficits and complications, as well as efficacy measures including progression-free survival and quality of life. A control group will receive standard treatment for comparison.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 to 75 with unifocal, unilobar high-grade gliomas eligible for complete surgical resection.

Not a fit: Patients with multilobar tumors, significant midline shifts, or other contraindications for surgery or treatment may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could improve surgical outcomes and overall survival for glioblastoma patients.

How similar studies have performed: While this approach is novel, similar studies have shown promise in improving outcomes for glioblastoma patients with neoadjuvant therapies.
