Irreversible electroporation in the curative treatment of Ewing's sarcoma.

Ewing's sarcoma (ES) is the second most common paediatric cancer of the bone. Standard therapy includes surgery or radiation for local control of primary and relapsed lesions and chemotherapy for systemic control. Irreversible electroporation (IRE), which uses short electrical pulses to induce pores and ablate neoplastic cells, has emerged as an alternative method of local control for inoperable metastatic liver and lung lesions. We present the first case in which IRE was used for local control of bony ES. This method has achieved successful local tumour control in our patient for 3 years.
