Key Clinical MessageThe combination of Irreversible Electroporation and Electrochemotherapy (IRECT) was well tolerated, safe, and had antitumor activity in this case study of a patient with lymph node metastases from gastric cancer. We therefore recommend the consideration of further clinical studies to investigate the treatment of cancerous tissue with IRECT.
Key Clinical MessageWe demonstrate feasibility and safety of Electrochemotherapy for treatment of a prostate cancer (PCa) with infiltration of the urethral sphincter. The patient remained continent and potent, toxicity was low, and 6 months of follow‐up showed no cancer activity. We conclude that Electrochemotherapy should be further evaluated as treatment strategy for locally advanced PCa.
A new minimally invasive tissue ablation technique, that combines the biophysical processes of electroporation and electrolysis, is introduced. The technology employs electrode needles inserted in the target tissue to deliver an Electrolytic Electroporation Waveform (EEW) in the form of an exponential decay voltage, several tens of microsecond long. A case study in a large animal model demonstrates that clinically significant size lesions can be achieved with a single, milliseconds long EEW. Ablation with EEW has major advantages over the comparable tissue ablation techniques of electrolysis, reversible electroporation and irreversible electroporation. EEW is orders of magnitude faster than conventional electrolytic ablation. EEW does not require the use of muscle relaxant as irreversible electroporation and EEW does not require injection of drugs as reversible electroporation. This new technology is simple to use and may become an important addition to the minimally invasive surgery armamentarium.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
