Objective: To evaluate early clinical and multiparametric prostate magnetic resonance imaging (mpMRI) results of irreversible electroporation (IRE) efficiency in treatment of localized prostate cancer.
Material and methods: For the patients in whom IRE was performed for local ablation, mpMRI was used for the sixth month follow-up. These images were compared with the mpMRI images obtained before the procedure. We performed transperineal fusion biopsy to patients with diagnosis of localized prostate cancer. We treated the eligible ones with IRE. Six of them have completed their 6-month follow-up period. We compared preoperative prostate specific antigen (PSA), international prostate symptom score, international index of erectile function (IIEF), and mpMRI of these patients with those obtained at the sixth month of follow-up. Side effects experienced by the patients were evaluated as well.
Results: We had 10 patients who received IRE treatment. Six patients completed their sixth month-follow-up and came for control visits. At the end of 6 months, the mean decrease in PSA level was 73%. IIEF results were seen not to have changed significantly. On mpMRI, diffusion restriction was seen to have disappeared except for one patient, and Prostate Imaging Reporting Data System scores were decreased.
Conclusion: We concluded that early clinical and mpMRI results for IRE in the focal ablative treatment of localized prostate cancer were gratifying. As an ambulatory procedure with a low incidence of side effects, we look forward to seeing the long-term results of IRE treatment.
