Percutaneous vertebroplasty as treatment of malignant vertebral lesions: a systematic review and GRADE evaluation resulting in a Danish national clinical guideline.

PURPOSE: To summarize the recommendations from the national clinical guideline published by the Danish Health Authority, regarding cemental augmentation as treatment for painful vertebral lesions, in patients with malignant disease. METHODS: A multidisciplinary working group formulated recommendations based on the GRADE approach. RESULTS: Two of the questions were based on randomized studies and one on professional consensus. The guideline recommends cemental augmentation for painful vertebral lesions in patients with malignant diagnosis, either hematological or non-hematological. Fracture of the posterior wall is not a contradiction to cemental augmentation, but care should always be taken while injecting the cement, to decrease the risk of cemental leaks into the spinal canal. CONCLUSION: The recommendations are based on low-to-moderate quality of evidence or professional consensus as well as patient preferences and positive and harmful effects of the intervention. The working group recommends more randomized studies on patients with different malignant diseases and painful vertebral lesions comparing percutaneous vertebroplasty/kyphoplasty and conservative treatment to confirm the conclusion in this guideline.
