入选标准
- •Age ≥ 18 years, Karnofsky Performance Index ≥
- •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 (i.e. non-CNS) tumor.
- •Adequate distance to optic nerve(s), chiasm and brainstem (organs at risk for radiotherapy).
- •Adequate birth control.
- •Informed consent.
排除标准
- •Leptomeningeal spread and dural attachment (assessed pre- and intraoperative).
- •Frozen section reveals primary CNS tumor, lymphoma, SCLC or germinoma.
- •Psychiatric or social condition potentially interfering with compliance.
- •Contraindication against anesthesia, surgery, MRI and/or contrast agents.
- •Pregnant or breast-feeding women.

结局指标
主要结局
Median local progression free survival (PFS)
时间窗: 12 months
Time span (in months) between surgery and recurrence within a 0,5 cm margin around the resection cavity, evaluated through Response Assessment in Neuro-Oncology (RANO) criteria for brain metastasis obtained from serial Magnetic resonance imaging (MRI) scans.

- Change in neurocognitive performance (compared to baseline): Repetition(6, and 12 months)
- Radiation-related (acute / early delayed / late) neurotoxicity(12 months)
- Median time to the initiation of systemic therapies(12 months)
- Change in neurocognitive performance (compared to baseline): Minimental(6, and 12 months)

- Quality of life (QoL)(6, and 12 months)
- Change in neurocognitive performance (compared to baseline): Trail making(6, and 12 months)
- Change in neurocognitive performance (compared to baseline): Oral(6, and 12 months)
