Design and procedures This is a prospective, controlled, explorative trial to investigate the neurological outcome after emergency radiotherapy in metastatic spinal cord compression of non-small cell lung cancer patients with acute neurological deficit. RT start within 12 hours after onset of neurological symptoms. The target parameters will be measured at the start of radiotherapy (t0), and six weeks after radiotherapy (RT) (t1). The target parameters comprise the documentation and completion of the ASIA Impairment Scale (AIS), and the recording of patient-specific data.
