Radiotherapy of Motor Deficits From Metastatic Epidural Spinal Cord Compression

The primary aim of this randomized multi-center trial is to investigate the efficacy of the
radiotherapy regimens 5 x 4 Gy and 10 x 3 Gy with respect to the effect on motor function in
patients with metastatic epidural spinal cord compression. The response rate (improvement in
motor function or prevention of progression) will be assessed at one month following
radiotherapy.

In addition, the following endpoints will be evaluated:

1. Motor function; additional assessments directly and at 3 and at 6 months after
radiotherapy

2. Ability to walk; assessment directly and at 1, 3 and 6 months after radiotherapy

3. Sensory function; assessment directly and at 1, 3 and 6 months after radiotherapy

4. Quality of life; evaluation directly and at 1, 3 and 6 months after radiotherapy

5. Pain assessment directly and at 1, 3 and 6 months after radiotherapy

6. Overall survival up to 6 months following radiotherapy

7. Local Progression-free survival up to 6 months following radiotherapy

Inclusion Criteria:

- Motor deficits of the lower extremities resulting from metastatic epidural spinal cord
compression, which have persisted for no longer than 30 days

- Confirmation of diagnosis by magnetic resonance imaging (spinal computed tomography
allowed)

- Relatively poor survival prognosis (defined as ≤35 points on the survival score
published in Cancer 2008)

- Written informed consent

Exclusion Criteria:

- Prior radiotherapy or surgery of the spinal areas affected by MESCC

- History of symptomatic brain tumor or symptomatic brain metastases

- Metastases of the cervical spine only

- Other severe neurological disorders

- Pregnancy, Lactation

- Indication for decompressive surgery + stabilization of the affected spinal areas
