Treatments for early or less aggressive disease are limited. Researchers want to test a device that destroys cancerous tissue with laser energy. They want to see if using it with ultrasound is more comfortable than using it with magnetic resonance imaging (MRI).\n\nObjectives:\n\nTo test a cooled laser applicator system to treat prostate cancer lesions. To see if ultrasound imaging is a practical and feasible treatment with laser ablation for focal prostate cancer treatment.\n\nEligibility:\n\nMen at least 18 years old with prostate cancer seen on MRI that has not spread in the body.\n\nDesign:\n\nParticipants will be screened with standard cancer care tests. These can include physical exam, lab tests, and MRI. For the MRI, they lie in a machine that takes pictures. Participants will have a prostate biopsy. Needle samples will be taken from 12 places in the prostate. This will be guided by MRI and ultrasound, which is obtained through a coil in the rectum.\n\nParticipants will stay at the clinic for 1 2 days. A cooling catheter (plastic tube) will be put in the bladder. Ultrasound will guide the laser applicator directly to the tumor.\n\nThe cooling catheter will be removed. A different catheter will be put in the urethra to keep the bladder emptied.\n\nThe next day, participants will have a physical exam and a PSA blood test.\n\nParticipants will have 6 follow-up visits over 3 years. At each visit, they will have a physical exam and lab tests. At some visits, they will also have an MRI or other scans and a prostate biopsy.","Background:\n\n* Pilot study to evaluate the feasibility of real time ultrasound imaging to guide focal thermal ablation of low to intermediate risk focal prostate tumors.\n* Prostate cancer is relatively slow growing, with doubling times for local tumors estimated at 2 to 4 years.\n* Recent patient series suggest that 20% to 30% of men undergoing radical prostatectomy have pathologic features in the radical prostatectomy specimen consistent with an insignificant or \"indolent\" cancer that poses little threat to life or health.\n* An NIH\u002FNCI protocol #11-C-0158 titled MR Image guided focal laser ablation therapy of prostate cancer has treated 15 patients without major complication over the past 5 years. Out of 15 patients, 3 have had evidence of disease recurrence (data from this study was published in Diagnostic and Interventional Radiology). This data are being prepared for publication (verbal communication with Peter Pinto, MD, principal investigator); however, it requires a very long and resource-intensive MRI imaging, which may be a barrier to broad translation to the community setting. Specialized custom and expensive MRI-compatible equipment is also required. Focal laser ablation for prostate cancer using the Tranberg CLS Thermal Therapy System and laser are FDA cleared.\n* Focal thermal ablation such as laser ablation or cryosurgery are standard of care therapies for prostate cancer, with cancer control comparable to that of external beam radiotherapy and brachytherapy.\n* NIH \u002F NCI clinical trials have performed MRI + ultrasound (US) fusion biopsy in nearly 3000 patients, \\> 40,000 biopsies over the past 18 years.\n* We propose to perform ultrasound (US) guided focal thermal ablation with fusion visualization and co-display of pre-acquired MRI during the treatment of patients.\n\nObjectives:\n\n-To determine the feasibility of treating biopsy-confirmed, US-targetable and\u002For MR-visible, low to intermediate risk prostate tumor(s) using ultrasound (US) image-guided focal interstitial thermal ablation.\n\nEligibility:\n\n* Patients must have organ confined, biopsy-confirmed, low or intermediate risk prostate cancer that is either US-targetable or MR visible, or both.\n* Men \\>= 18 years of age.\n\nDesign:\n\n* Pilot study, testing feasibility of ultrasound-guided thermal ablation of focal prostate cancer.\n* A total of 30 patients will be enrolled to yield 20 evaluable patients",[19,20],"Prostate Cancer","Prostate Neoplasms",[22,23,24,25,26],"Thermal Ablation","Localized Prostate Cancer","Medtronic-Visualase","Thermal Damage","PSA Levels","INTERVENTIONAL","DEVICE_FEASIBILITY",[30],"NA",{"count":32,"type":33},30,"ESTIMATED",[35],{"type":36,"name":37,"description":38,"armGroupLabels":39},"DEVICE","ultrasound image-guided ablation device","ultrasound image-guided focal ablation - may be either laser ablation or cryotherapy",[40],"1",[42],{"measure":43,"description":44,"timeFrame":45},"To determine the feasibility of treating biopsy-confirmed and MR-visible, low-grade prostate tumor(s) using ultrasound (US) image-guided focal interstitial thermal ablation","Assessment of thermal damage outside of intended treatment areas as measured by post contrast MRI, and the frequency of other adverse events and complications.","duration of protocol",[47,50],{"measure":48,"timeFrame":49},"To determine changes in imaging and biopsy characteristics after thermal ablation of prostate cancer.","3 years after treatment completed",{"measure":51,"timeFrame":52},"To analyze circulating tumor markers and functional markers in individuals with prostate cancer after receiving treatment over time","2 weeks after the ablation.","MALE","18 Years","100 Years",false,{"inclusion":58,"exclusion":76,"raw_text":84},[59,60,61,62,63,64,65,66,67,68,69,70,71,72,73,74,75],"Enrollment open only to current NIH patients enrolled in 16-C-0010.","Patients","Prostate cancer diagnosed by transrectal or transperineal US-guided standard 12 core needle biopsy, MR image-guided needle biopsy, or MR\u002FUS fusion-guided needle biopsies or biopsies performed under semi-automated tools.","Targeted tumors must be considered a safe distance (\\>= 8 mm) from the urethra, rectal wall, bladder wall or neurovascular bundle by the Principal Investigator.","Must have had a prostate MRI performed at the NIH within 12 months prior to enrollment.","Must have had a prostate biopsy performed at NIH within 12 months (+2 months) prior to enrollment.","Men \\>18 years of age.","ECOG performance status \\\u003C=2.","Patients must have adequate organ and marrow function as defined below:","leukocytes: \\>=3,000\u002FmcL","absolute neutrophil count: \\>=1,500\u002FmcL","platelets: \\>=75,000\u002FmcL","creatinine: within normal institutional limits","creatinine clearance: \\>=60 mL\u002Fmin\u002F1.73 m2 for patients with creatinine levels above institutional normal.","Preoperative clearance by NIH Department of Anesthesia and Surgical Services","Ability of subject to understand and the willingness to sign a written informed consent document.","Subject understands that this is an experimental protocol and that there are available standard treatment options.
