NCT04847284

Brief Summary

Intraoperative radiotherapy (IORT) is a new alternative for local radiotherapy with the advantages of dose escalation, reduced overall treatment time, and enhanced patient convenience, however the degree of efficacy is unknown, as well as and which is the most efficient dose. The objective of this study is to evaluate the efficacy and safety of IORT in patients with surgical excision of brain metastases at a dose of 20 Gy is at least as effective and safe as other forms of radiation therapy in patients with resection of brain metastases.

Outcome Measures

Primary Outcomes (3)

  • Median local progression free survival (lPFS)

    Recurrence within a 0.5 cm margin around the resection cavity, assessed by serial magnetic resonance imaging (MRI scans) and response assessment criteria in neuro-oncology (RANO)

    6 months from the date of surgery.

  • Radiation-related acute neurotoxicity

    Neurotoxicity related to radiotherapy evaluated according to the scale of the Common Terminology Criteria for Adverse Events (CTCAE) version 5. Score from 0 to 5, with 5 being the worst toxicity \- Acute toxicity: cerebral edema

    3 months from the date of surgery.

  • Radiation-related late neurotoxicity

    Neurotoxicity related to radiotherapy evaluated according to the scale of the Common Terminology Criteria for Adverse Events (CTCAE) version 5. Score from 0 to 5, with 5 being the worst toxicity \- Late toxicity: radionecrosis.

    6 months from the date of surgery.

Secondary Outcomes (3)

  • Median regional PFS (rPFS)

    6 months from the date of surgery

  • Global PFS (gPFS)

    6 months from the date of surgery

  • Median overall survival (OS)

    6 months from the date of surgery

Study Arms (1)

Single arms

EXPERIMENTAL

To determine the efficiency and safety of IORT with low-energy photons to the cavity after resection of brain metastases

Radiation: Intraoperative radiotherapy

Interventions

Intraoperative radiotherapy application immediately following resection of brain metastases.

Single arms

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Age ≥ 18 years
  • Karnofsky Performance Status ≥ 70
  • Newly diagnosed cerebral or cerebellar lesion (contrast enhancing on a T1-weighted MRI scan) amenable to total resection with no dural attachment
  • Frozen section confirming a metastasis of an extracranial ( Central Nervous System i.e. non-CNS) tumor
  • Adequate distance to optic nerve(s), chiasm and brainstem (organs at risk for radiotherapy)
  • Adequate birth control

You may not qualify if:

  • Leptomeningeal spread and dural attachment (assessed pre- and intraoperatively)
  • Frozen section reveals primary CNS tumor, lymphoma, SCLC (Small-cell lung cancer) or germinoma
  • More than one brain metastasis
  • Psychiatric or social condition potentially interfering with compliance
  • Contraindication against anesthesia, surgery, MRI and/or contrast agents
  • Pregnant or breast-feeding women
