Brief Summary

Most prostate cancer treatment research in the last decade has been focused on trying to improve quality of life, while maintaining a high level of cancer control. However, the concept of Focal treatment is proposed as an intermediate option between active surveillance and treatment of the whole prostate. Focal ablation aims to efficiently treat the localized cancer while reducing complications related to standard treatments, including the risks of incontinence and impotence. Focal Irreversible Electroporation (IRE) delivered by NanoKnife System is composed of the NanoKnife Generator and NanoKnife Single Electrode Probes. With IRE, an electrical current is delivered between a pair of probes in a series of pulses. These pulses create irreversible pores in cell membranes and lead to cell death which allow for only the tissue between these probes being destroyed. The aim of this study is to analyze the safety and efficacy of transperineal IRE treatments in intermediate risk anteriorly localized prostate cancer patients.

Study Arms (1)

Irreversible Electroporation (IRE) treatment

EXPERIMENTAL

Focal Irreversible Electroporation (IRE) delivered by NanoKnife System is composed of the NanoKnife Generator and NanoKnife Single Electrode Probes.With the NanoKnife System, electrical current is delivered between pairs of probes in a series of pulses. The waveform of the current is adjustable as determined by clinician chosen parameters. Up to six probes may be placed in an array within the tissue. The probes of the array are matched as pairs by the system. When probes are activated via a foot pedal, the scheduled current is delivered to tissue between subsequent pairs of probes. Soft tissue between the probes is ablated.

Device: Irreversible Electroporation (IRE)

Interventions

Irreversible Electroporation (IRE) DEVICE

The area of the prostate that was positive for cancer based on the transperineal prostate biopsy will be targeted for ablation via the NanoKnife System. An MRI/TRUS fusion device probe will be placed in the rectum and the prostate will be visualized in both sagittal and axial views. The ultrasound grid which was used during the mapping biopsy will be oriented using anatomical landmarks and used to identify the location of the positive biopsy cores. The NanoKnife Single Electrode Probes will be surgically inserted into the prostate through the perineum using MRI/TRUS fusion guidance and the ultrasound grid for guidance.
