Irreversibele elektroporatie

Irreversible electroporation (IRE) employs high-voltage electrical pulses for non-thermal image-guided tumor ablation in solid organs. The pulses disrupt the membrane potential of all cells within the ablation zone causing loss of tumour cell homeostasis resulting in death. IRE has the advantage of sparing extracellular matrix structures and thereby preserving the anatomical integrity of blood vessels, bile ducts, and ureters. This trait distinguishes IRE from more commonly used thermal ablation techniques like microwave- and radiofrequency ablation. Several prospective phase-1 and -2 studies demonstrated the safety and efficacy of IRE for the treatment of central liver, locally advanced pancreatic, and local prostate tumours. In addition, IRE induces a systemic immune response. When this immune effect can be amplified by combinatory treatment with immunotherapeutic drugs its synergy might form a bridge between local and systemic therapies with the potential to develop into a fundamentally new approach to cancer treatment.
