Purpose or Objective: To evaluate the feasibility and effectiveness of combining radiofrequency (RF), cementoplasty (CP) and Radiotherapy (RT) for pain treatment of bone metastasis (mts) in oligo-metastatic patients (pts). Material and Methods: From April 2015 to September 2015 twelve pts. (9 men, 3 women; median age 64 years) with 12 injuries to bones (vertebral column n = 9; femur, n = 1; sacrum, n = 2) were treated. Diagnosis of bone mts and then its treatment should be based on the

The mini-invasive treatment of oligometastatic pts aims pain relief that improving the quality of life; treat biomechanical stability of the spine; and an antineoplastic effect -cytoreductive. RF ablation was performed with the pts under sedation a CT -guidance, and was followed by cement injection. Pain relief was valuated with visual analogue scale (VAS) score. After 10 days on average, the patient was subjected to Stereotactic-RT or Volumetric Modulated Arc Therapy (VMAT) technique and a total dose of 20-30 Gy. Results: Technical success and pain relief was archived in all pts. Pain rating with the VAS decrease from a mean of 9 to a mean of 4, and after 3 month was detected a mayor decrease (2,5). We recorded an overall improvement in the quality of life measured with a suitable test There was no particular toxicity. At present no patient died for progression of disease.The evolution of the disease will be evaluated with the use of MRI. Conclusion: Our data showing the importance of a multidisciplinary approach oligo-metastatic patients. RF with CP and RT carried out by experts is effective for pain relief and functional recovery in patients with painful bone metastases and can significantly improve quality of life.
