This clinical research study is designed to determine the ability of in bore MRI guided Focal Laser Ablation (MRgFLA) in patients with early stage carcinoma of prostate. The results will be evaluated by repeated MRI and prostate biopsy. Previous prospective development study demonstrated that FLA may be a viable option for men with low-intermediate risk prostate cancer. The vast majority of patients undergoing this treatment experienced minimal side effects with no peri-operative complications. Over 80% of patients treated with MRgFLA remain on AS and were able to avoid radical therapy at mean follow up duration of 3 years.

Eligibility |
Inclusion Criteria: - Men 40-80 years of age; - Histologically-proven low-intermediate risk prostate carcinoma; (Gleason score = 7, primary grade = 4) - Prostate cancer clinical stage T1c and T2 - MR site suspicious for cancer or cancer mapped to one lobe of the prostate using the 3D hybrid Trans-rectal ultrasound (TRUS) device - Size of MR visible tumor <20mm - Suspicious site on Prostate MRI must coincide with sector positive for cancer on biopsy. - Prostate specific antigen (PSA) level less than 15 ng/mL - IPSS, International Consultation on Incontinence Questionnaire-Urinary Incontinence-Short Form (ICIQ-UI SF), IIEF complete prior to procedure - Life expectancy of greater than 10 years, based on co-morbidity not related to prostate cancer. Exclusion Criteria: - Medically unfit for focal therapy of the prostate - Patients who are unwilling or unable to give informed consent; - Patients who have received androgen suppression therapy - Patients who have received or are receiving chemotherapy for prostate carcinoma; - Patients previously treated with surgery to the prostate (traditional, endoscopic or minimally invasive including High-Intensity Focused Ultrasound (HIFU), Transurethral Needle Ablation (TUNA), Radiofrequency Interstitial Tumor Ablation (RITA), microwave, cryotherapy or any curative treatment - Patients who have undergone radiation therapy for prostate cancer or to the pelvis - Any condition, or history of illness or surgery that, in the opinion of the Investigator, might confound the results of the study or pose additional risks to the patient (e.g. significant cardiovascular conditions or allergies); - Patients with a history of non compliance with medical therapy and/or medical recommendations; - Patients who are unwilling or unable to complete the patient self-assessment questionnaires; - Chronic or acute prostatitis, neurogenic bladder, urinary tract infection, sphincter abnormalities, or any other symptom that prevents normal micturition. - Patients who have participated in a clinical study and/or received treatment with an investigational treatment and/or product within the past 90 days; - Patients with contraindication to MRI (i.e. pacemaker, hip prosthesis, severe claustrophobia, brain aneurysm clip, allergy to MRI contrast agent) - Any condition, or history of illness that, in the opinion of the investigator will confound or increase the patient risk during the study |

Primary | The proportion of study patients clinically free of clinically significant PCa (i.e. requires definitive treatment) | Clinically significant PCa will be defined as recurrent/residual Gleason 3+4 or higher, and/or high volume Gleason 6 disease found at 6 month biopsy. | 6 months after treatment completion | |
Primary | The proportion of study patients clinically free of clinically significant PCa (i.e. requires definitive treatment) | Clinically significant PCa will be defined as recurrent/residual Gleason 3+4 or higher, and/or high volume Gleason 6 disease found at 24 month biopsy. | 24 months after treatment completion | |
Secondary | Treatment effect on patients' Quality of Life (QoL), the following validated self-reported urogenital functioning assessment instruments will be used before and following treatment at pre-specified interval | Validate Patient-Reported Questionnaire (International Prostate Symptom Score, scale from 0-7 mild, 8-19 moderate, 20-35 severe symptoms, higher values being worse, averages at different time points will be noted to assess improvement, decline or baseline) will be completed by participants throughout the study to assess Health Related Quality of Life. | Baseline before treatment, 30 days, 6 months, 12 months and at 24 months following treatment | |
Secondary | Treatment effect on patients' Quality of Life (QoL), the following validated self-reported urogenital functioning assessment instruments will be used before and following treatment at pre-specified interval | Validate Patient-Reported Questionnaire (International Index of Erectile Function-15, higher scores are better, averages at each specified interval will be taken once all subjects reach the interval and study completion) will be completed by participants throughout the study to assess Health Related Quality of Life. | Baseline before treatment, 30 days, 6 months, 12 months and at 24 months following treatment |
