Prostate Irreversible Electroporation Study
Sponsor: Chinese University of Hong Kong
Summary
Conventional treatment options for localized prostate cancer include prostatectomy, radiotherapy and active surveillance. However, prostatectomy and radiotherapy carry certain degree of morbidity, including the risks of urinary incontinence, erectile dysfunction and injury to the structures in the proximity. Active surveillance carries the risk of disease progression and psychological distress to the patients. Focal therapy employs the concept of only destroying the significant lesion, resulting in disease cure and improved functional outcome. Among the different options of focal therapy, Irreversible electroporation has evolved over the past decades and can be a reliable treatment option. Our study aims at assess the safety and effectiveness of such treatment in prostate cancer management.

Prostate Irreversible Electroporation
The Prostate Irreversible Electroporation procedure was performed in our institution by a single urologist using an Prostate Irreversible Electroporation device and 18-gauge electrodes (Nanoknife®; Angiodynamics, Queensbury, NY, USA). All patients were positioned in lithotomy position under general anesthesia. A transrectal ultrasound was used to visualize the prostate and a brachytherapy grid was used to place the electrodes. An indwelling catheter was placed to empty the bladder. Four to six electrodes were placed through the perineum via the template grid to surround the targeted lesion. The lesion was defined based on prostate biopsy and MRI images. The active tip varied between 15- and 20-mm exposure. The distances between the electrodes were measured using TRUS and entered into the Nanoknife system. An initial ten pulses were delivered to ensure sufficient current was delivered between the electrodes (20-40 A). If sufficient then the remaining 80 pulses were given.
