Aims and objectives
To evaluate the effectiveness of percutaneous Ct-guided ablation with RF or MW or CRYO added to RT versus RT only in the relief of bone metastasiss pain.
Methods and materials
From May 2007,
49 oncologic patients were evaluated for a single painful bone metastasis.
All lesions were larger than 3 cm with a central poorly oxygenated and necrotic area.
Before ablation treatment for each patient we realized a validated visual analogic scale (VAS) for pain assessment.
Inclusion criteria was VAS from 4 to 10.
Exclusion criteria was the presence of other metastasis.
Ablòation had the role to destroy the necrotic center,
which is unlikely to be treated by RT.
By CT-guiding the ablation was done...
Results
Patients had pain relief for a period from 3 to 15 months (mean 8.1 months for CRYO,
7.4 for 7.4 for RF and 7.0 for MW) versus 3 to 15 months ( mean 2.4-3 months) of (RT).
Technical success was 100%.
No major complications occurred.
The mean VAS after allo ablations improved overall by 80% from 9,1 to 1,1 (mean 7,1).
Conclusion
These datas suggest that,
in comparison with RT only,
tha adding of RF of MW or CRYO ablation can lead to a significant improvement interms of pain relief in patients with painful bone metastasis.
