Randomized Trial of Vertebroplasty and Radiotherapy Versus Radiotherapy Alone for Osseous Spine Metastases
Randomized Trial of Vertebroplasty and Radiotherapy Versus Radiotherapy Alone for Osseous Spine Metastases
A randomized phase III study of palliative external beam radiotherapy (RTOG 97-14) has shown that 8 Gy in a single fraction is very effective in providing pain relief, with complete or partial improvement in pain seen in 66% of patients with bone metastases. Percutaneous vertebroplasty (PV) is a technique designed to consolidate pathologic vertebral bodies through the injection of orthopaedic cement under fluoroscopic guidance. Consolidation provides rapid pain relief to painful vertebral body lesions secondary to osteoporosis, haemangiomas, myeloma and metastatic diseases, with complete or partial improvement in pain seen in 70-85% of patients. To date, no randomized trial has tested the association of vertebroplasty and radiotherapy to enhance pain relief for patients with painful osseous spine metastases.
A randomized trial has been designed to determine whether vertebroplasty and radiotherapy (8 Gy in a single fraction) provide enhancement pain and narcotic relief compared to radiotherapy alone for patients with painful osseous spine metastases
Patients with 1 to 4 painful osseous spine metastases are randomized to 1 of 2 treatment arms:
