Brief Summary

Irreversible electroporation is a non-thermal ablative technology that uses high-voltage electric pulses to create permanent nanopores in tumor cell membranes, leading to apoptosis or other forms of cell death. Because the mechanism is primarily non-thermal, IRE may better preserve extracellular matrix, bile ducts, vessels, and other critical structures than thermal ablation, which is relevant for tumors adjacent to major vascular or biliary anatomy. The main anticipated clinical value of IRE in these protocols is local disease control and potential survival benefit when used after induction therapy in patients with non-progressive disease. The procedure may be performed by open or percutaneous access according to tumor location, safety considerations, and institutional expertise. Perioperative management, imaging guidance, and post-procedure monitoring will follow institutional standards. Post-IRE gastrointestinal dysfunction may occur. Symptom-directed supportive care, including electroacupuncture where appropriate and approved by the investigator, may be used as supportive management. Such care is not intended to replace oncologic treatment and will be recorded as concomitant treatment when administered.
