Clinical considerations of bleomycin based electrochemotherapy with variable electrode geometry electrodes for inoperable, deep-seated soft tissue sarcomas.

The aim of the current prospective pilot study exclusively for deep-seated soft tissue sarcomas (STS) was to evaluate efficacy and safety of bleomycin-based ECT using VEG (variable electrode geometry) electrodes. During a 2-year period, seven surgically inoperable STSs were treated at the University of Szeged, Department of Surgery in Hungary. Electrode placement was determined by software planning using preoperative imaging (CT/MRI) and intraoperative ultrasound.
