Spots Global Cancer Trial Database for Prostate Cancer IRE Study (PRIS)

Study Description

Brief Summary: The aim of this study is to evaluate the feasibility to treat localized prostate cancer diagnosed with MRI and targeted/systematic biopsies, with IRE in comparison with conventional radical treatments with the primary objective to locally control the tumour with a minimum of side effects.

Detailed Description: OBJECTIVES The aim of the proposed research is to evaluate the cancer control, genitourinary, rectal and overall health-related quality of life outcomes of focal therapy for unifocal localized prostate cancer using irreversible electroporation (IRE). PRIMARY AIM • To evaluate functional outcomes in men treated for unifocal ISUP 2-3 localized prostate cancer with focal treatment in comparison to conventional treatment with either radical prostatectomy or radiation therapy SECONDARY AIMS * To evaluate adverse events in men treated for unilfocal ISUP 2-3 localized prostate cancer with focal treatment in comparison to conventional treatment with either radical prostatectomy or radiation therapy * To evaluate progression free and treatment free survival in men treated for unifocal ISUP 2-3 localized prostate cancer with focal treatment in comparison to conventional treatment with either radical prostatectomy or radiation therapy * Economic evaluation of each technique TRIAL DESIGN This study is a randomized controlled exploratory trial comparing focal therapy to conventional radical treatment of prostate cancer with the primary aim to evaluate functional outcomes 12 months after treatment. Patients will be included from 4 different hospitals within the Stockholm County; Karolinska University Hospital, Danderyd Hospital, St Görans Hospital, Södersjukhuset. Eligible patients, after MRI and targeted/systematic biopsies, will be men with clinically significant intermediate-risk PCa or dominant unifocal clinically significant intermediate-risk and small contralateral low-risk disease without previous history of prostate cancer treatment. Potential study participants will have a visit scheduled together with an urologist and oncologist, where a treatment decision of radical prostatectomy or radiation therapy will be done together with the patient. At this visit the patient will receive oral and written information about the study. If the patient is interested in participating, a baseline visit is scheduled during which informed consent is obtained and the patient randomized to one of two standard treatments or focal treatment. Patients eligible for radical prostatectomy will be randomized in study 1 to focal treatment or radical prostatectomy. Patients eligible for radiation therapy will be randomized in study 2 to focal treatment or radiation therapy. Time between randomization and treatment will be \<= 6 weeks. Patients will be asked to fill out study specific questionnaires with questions on functional outcomes and quality of life. Main outcome measurement in study 1 will be urinary incontinence at 12 months post treatment and in study 2 irritative urinary symptoms 12 months post treatment. Further outcomes will be erectile dysfunction, adverse events, progression-free and treatment-free survival.
