Summary
Brief summary (as posted)
Bone metastasis causes bone destruction and skeletal related events (SRE) including compression fracture, hypercalcemia, and spinal cord compression. Therefore, palliative treatments for pain control and local control have become important and multidisciplinary multimodality approach is needed for treatment of bone metastasis. The efficacy of radiotherapy (RT) for bone metastasis is well known. And the results that bisphosphonate decreases SRE in patients with solid tumor and multiple myeloma reported. In previous retrospective reports, the combination of local RT and systemic bisphosphonate was more effective than RT alone. Therefore, Investigators designed a phase II study to evaluate the efficacy of RT in combination with zoledronic acid on pain relief and the safety of RT in bone metastasis patients with gastrointestinal tumors.

Primary outcomes (1)
- measure
- Pain relief rate
- timeFrame
- Change from baseline pain extent at 1,3,6 months
Secondary outcomes (2)
- measure
- skeletal related events (fracture and spinal cord compression)
- timeFrame
- at 18months after the IRB approval
- description
- skeletal related events (SRE) (fracture, spinal cord compression due to metastasis requiring operation or radiotherapy. Occurence of pain is not regarded as SRE.) (SRE including fracture will be evaluated with plain X-ray at 1 month after completion of RT, and plain X-ray and MRI at 3 months after completion of RT. all imaging studies will be reviwed by clinician and radiologist.)
