Methods and Materials
From may 2007,
31 oncologic patients who subsequently developed single painful bone metastases in absence of other visceral metastases.
All bone lesion were larger than 3 cm with a central poorly oxygenated and necrotic area.
Before undergoing ablation treatment,
patients were evaluated by means of a validated visual analogue scale (VAS) for pain assessment. Inclusion criteria were VAS from 4 to 10.
Exclusion criteria were the presence of other visceral or not-visceral metastasized site.
The role of ablation is to burn the necrotic center,
which is unlikely to be attacked by radiotherapy .
We treated 21 patients with CT-guided-RFTA ( LeVeen needle electrode Boston Scientific Corporation),
6 patients with microwave ablation (Single Evident MWA Surgical Antenna,
Covidien),
4 cases were treated with cryoablation system (IceSeed,
Galil Medical).
All ablation procedure were followed after 6 days by single fraction radiotherapy at 800 cGy.
