Is this trial a fit for you?

Likely a good fit

Adults (18+) with histologically confirmed IDH-wildtype GBM, planned for adjuvant radiochemotherapy, and suitable for LITT within one week of pre-radiation planning MRI.

Probably not a fit

Patients with contraindications to LITT, inability to proceed with planned radiochemotherapy, or with disease characteristics not amenable to focal ablation may not benefit.

What this trial studies

Glioblastoma remains highly aggressive even after initial surgery and chemoradiation. In many patients, a focal tumor recurrence appears between the first postoperative MRI and the start of radiotherapy, which is linked to poorer survival. The trial investigates using Laser Interstitial Thermal Therapy (LITT) to ablate this ultra-early recurrence within a tight 1-week window before adjuvant therapy, aiming to avoid delaying treatment and potentially improve outcomes. LITT is already used for similar brain lesions and may also sensitize tumors to subsequent radiotherapy and chemotherapy. This interventional study will assess feasibility, safety, and potential plan for integration into standard care without prolonging the overall treatment timeline.

Why it matters

Potential benefit: If successful, LITT could allow timely adjuvant therapy and possibly improve survival for patients with ultra-early GBM recurrence.

How similar studies have gone: LITT has shown benefit in select GBM recurrences and metastases, but applying it within an ultra-early pre-radiation window is relatively novel.
