Comparing Two Different Boost Approaches in Radiation Therapy for People With Prostate Cancer

Summary

In this study we will find out whether the use of a new type of boost approach called irreversible electroporation (IRE) is as effective as the standard boost approach of radiation therapy for people with intermediate-risk prostate cancer receiving standard stereotactic body radiotherapy (SBRT).

Eligibility

Inclusion Criteria:

* Active urinary tract infection (UTI) at the time of IRE or biopsy; must be treated and resolved prior to proceeding
* Actively bleeding, known bleeding disorder, or inability to interrupt anticoagulants/antiplatelet therapy as clinically indicated for biopsy/IRE safety
* Any history of cardiac arrhythmia or epilepsy, or recent myocardial infarction, consistent with NanoKnife contraindication statements
