Laser zaps prostate tumors without major surgery
NCT ID NCT03650595
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a laser treatment guided by MRI to destroy early-stage prostate cancer in men aged 40-80 with low to intermediate risk. The goal is to control the cancer and avoid more aggressive treatments like surgery or radiation. Researchers will check results with follow-up MRIs and biopsies over two years.

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 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 \<15 ng/mL * IPSS, 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 HIFU, TUNA, 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 noncompliance 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
