Micro-ultrasound-Guided Focal Laser Ablation for Intermediate-Risk Prostate Cancer: Safety & Effectiveness

Inclusion Criteria: * Men 40-80 years of age. * Histologically-proven intermediate-risk PCa (Gleason score 7, primary grade ≤ 4). * PCa clinical stage T1c or T2. * MRI/MicroUS site suspicious for cancer or cancer mapped to one prostate lobe. * Maximum dimension of MRI/MicroUS visible tumour ≤15mm. * Suspicious site on Prostate MRI/MicroUS must coincide with sector positive for cancer on biopsy. * Prostate specific antigen (PSA) level \< 15 ng/mL. * IPSS, ICIQ-UI-SF, IIEF-15 questionnaires completed prior to the procedure. * Life expectancy of greater than 10 years, based on co-morbidity not related to PCa. Exclusion Criteria: * Maximum dimension of MRI/MicroUS visible tumour \> 15 mm. * Patients 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 HIFU, TUNA, RITA, microwave, cryotherapy or any curative treatment. * Patients who have undergone radiation therapy for PCa 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)
