Detailed Description
Rationale: Sixty-five percent of cancer patients with terminal illness have bone metastases, with debilitating pain as devastating consequence. The spine is the most common location for bone metastases. Spinal cord compression is present in 10% of patients with vertebral metastases and aggravates pain and performance status even further. Standard treatment of unstable vertebral metastases consists of stabilizing surgery, followed by external beam radiotherapy (8 Gy) after two weeks. Although this approach is effective in 60-70% of patients, it is has several downsides. Firstly, because of the two weeks interval between surgery and external beam radiotherapy, necessary for sufficient wound healing, it takes a long time before radiotherapy induced pain relief is achieved. Scatter artifacts on planning computed tomography images caused by surgical implants prohibit high-resolution imaging and accurate targeting of the lesion. Multiple hospital visits (+/- 10) are needed for administration of external beam irradiation, and in about 30-40% of patients no adequate pain response is achieved. An alternative treatment strategy, which would lead to faster pain relief in a higher proportion of patients with less hospital visits, would be highly desirable from the patient's perspective.
Objective: To assess the feasibility and safety of combining stereotactic body radiotherapy (SBRT) and pedicle screw fixation in a 48-hour window for the treatment of painful unstable metastases of the thoracic and/or lumbar spine.
Study design: Prospective case series (13), first in man study, Phase I and II a study according to the IDEAL recommendations
Study population: All patients, male and female, with impending spinal stability requiring radiation therapy and surgical intervention at the University Medical Center Utrecht
Main study parameters/endpoints: The main outcome of this study is safety of the combined procedure, defined as grade 3 or higher treatment-induced toxicity according to common terminology criteria for adverse events (CTC-AE) 4.0 as a result of the procedure within 60 days after the surgery.
