Current treatment standard for patients with metastatic spinal cord compression (MSCC) is decompressive surgery followed by radiotherapy. Stereotactic radiosurgery (SRS) could be considered a treatment option for MSCC for patients with minor neurologic deficits. If SRS is safely and effectively delivered with equivalent functional outcome, the patients would avoid the risks associated with an invasive procedure. This paper presents the design of a non-inferiority clinical trial evaluating the safety, tolerability and feasibility of SRS vs. current standard treatment for patients with MSCC. Patients fulfilling inclusion criteria will be randomized 1:1 to each arm. The primary endpoint is ability to walk six weeks after treatment. Secondary endpoints are levels of pain, bladder control, quality of life, response rate, toxicity and number of treatment days. 65 patients in each arm are required for the power of 89% to detect a clinically relevant inferior outcome.
