Introduction: Bone metastatic disease is a major cause of pain and decreased quality of life in patients with cancer. In addition to systemic therapy and pain control with narcotic analgesics, standard local treatments include palliation with radiation therapy and surgery. However, 20–30 % of patients do not respond to conventional treatments, increasing the interest in alternative therapies. We present the results of a new minimally invasive technique in the treatment of bone metastases.Methods: Twenty‐nine patients affected by painful bone metastases were treated with electrochemotherapy (ECT) from July 2009 to July 2011; the mean age was 60 years (range 37–87); 21 patients received a previous ineffective local treatment; the appendicular skeleton was affected in 15 patients while in 14 patients other sites were involved. ECT was performed using the Cliniporator Vitae under fluoroscopy or CT guidance depending on the site of the lesion. Clinical response was assessed using VAS scale and objective tumour response was evaluated according to the MD Anderson criteria for bone metastases.Results: All patients well tolerated the procedure and no intraoperative or postoperative complications were observed. At a mean follow‐up of 7 months, 24 patients were available for evaluation. 84 % of the patients (20 out of 24) referred improvement of pain ≥50 % with reduction of narcotics consumption. Radiographic evaluation after 3 months in 20 evaluable patients, showed “partial response” in 1 patient, “stable disease” in 17 and “progression” in two cases.Discussion: Results reported in this study demonstrated ECT to be safe and feasible in the treatment of painful bone metastases even when other previous treatments were ineffective. Pain and disease progression control was achieved in the majority of the patients with consequent improvement of quality of life.Conclusion: ECT should be considered a new feasible tool in the treatment of bone metastases in place or in combination with standard treatments; further developments are required to extend the use of this technique to spine metastases.

Resection of the distal end of the radius is indicated in the treatment of locally aggressive primary benign and malignant bone tumours. The aim of this study was to evaluate the technique of osteoarticular allograft reconstruction of this bone defect. We analysed 12 patients retrospectively with a minimum follow-up of 2 years (range 26–145 months, median 52 months). Three patients had a malignant tumour and nine had a giant cell tumour. The patients ages ranged from 13 to 65 years. The mean resected length of the radius was 6.6 (range 4–14) cm. Non-union of the osteotomy line was diagnosed 6 months after surgery in one case and needed bone grafting. Distal radio–ulnar joint instability was observed in eight cases. Subchondral bone alterations and joint narrowing were present in all cases but were painful in only one patient. The mean range of motion was 51° of flexion and 37° of extension.
