Background:

The ability to treat early prostate cancer is still limited. Thermal ablation methods are being tested for focal prostate cancer therapy. Researchers want to improve on these methods.

Objective:

To understand if Transurethral UltraSound Ablation (TULSA) in combination with MRI guidance is useful to treat localized prostate cancer.

Eligibility:

English-speaking adults ages 18 and older with localized prostate cancer that can be seen on MRI and can be treated by thermal ablation.

Design:

Participants will be screened with the following:

-Medical history

-Physical exam

-Digital rectal exam

-Blood and urine tests

-Electrocardiogram

-Tumor biopsy

-Questionnaire to assess urinary tract symptoms

-MRI of the pelvis. The MRI scanner is a long, narrow tube. Participants will lie on a bed that moves in and out of the scanner.

Participants may also be screened with the following:

-Echocardiogram

-Chest x-ray

-Bone scan

-Urodynamic studies to see how well the bladder, sphincters, and urethra hold and release urine

-MRI of the brain

-Transrectal ultrasound

-Computer tomography (CT) scan of the chest, abdomen, and pelvis. A CT scan is a series of x-ray images taken of parts of the body.

Some screening tests will be repeated during the study.

Participants will have the TULSA procedure. They will have an MRI for guidance. A small ultrasound applicator will be placed into their urethra. It uses heat to destroy the cancer areas in the prostate. It is controlled by a robotic arm. A cooling catheter will be placed into their rectum.

Participants will use a urethral catheter for 1-7 days.

Participants will have follow-up visits at 3, 6, 12, 18, 24, and 36 months.

Eligibility

INCLUSION CRITERIA:

Subjects must have prostate cancer amenable for ultrasound ablation defined as:

- diagnosed by transrectal ultrasound-guided prostate biopsy via standard 12 core biopsy and targeted biopsy of any MRI-visible or tracked lesions; pathological diagnosis must be confirmed by Laboratory of Pathology, NCI;

- Gleason Score <= 7;

- MRI-visible or MRI-tracked prostate cancer. This includes prostate cancer found on targeted biopsy of MRI-visible or MRI-tracked lesion. Histologically positive standard biopsy cores of Grade Group >= 2 prostate cancer must be from an area overlying or within 1cm of an MRI-visible or tracked lesion(s) and reviewed by NCI urologic pathologist. (Left / Right, Base, Mid-Gland, Apex). Systematic and targeted cores of Grade Group 1 prostate cancer outside of proposed ablation zone do not affect inclusion status, as these can be observed by conventional guideline management.

- organ confined clinical T1c or clinical T2a prostate cancer that is visualized on MRI. Note: Participants after prostate cancer treatment with local recurrence or residual tumor which is visible on MRI are eligible.

- PSA < 20 ng/ml or PSA >20 with a PSA density <0.15.

- Adults (>= 18 years of age)

- Participants must have adequate organ and marrow function as defined below:

Platelets >= 50,000/mcL

Hemoglobin >= 8 g/dL

Measured or calculated creatinine clearance (CrCl) (eGFR may also be used in place of CrCl)* >= 30 mL/min/1.73 m^2

GFR=glomerular filtration rate; ULN=upper limit of normal.

*Creatinine clearance (CrCl) or eGFR should be calculated per institutional standard.

- Subjects must be able to understand and willing to sign a written informed consent document.

- Subjects must be co-enrolled to NCI protocol 16-C-0010 "Care of the Prostate Cancer Patient and Prospective Procurement of Prostate Cancer Tissue."

EXCLUSION CRITERIA:

- Targeted lesion ablation length from apex to base of >5 cm or lesion extending >3 cm from the urethra.

- Target ablation volume greater than 100 ml.

- Presence of calcifications that would impede ultrasound transmission between the urethra and ablative target.

- Participants are unable to tolerate MRI (foreign body, i.e., pacemaker or other implanted device; claustrophobia; inability to tolerate rectal coil; etc.)

- Acute urinary tract infection

- Lower urinary tract symptoms defined by an IPSS > 20

- Participants with uncontrolled coagulopathies (including liver dysfunction, or untreated hereditary coagulopathies which have a standard of care treatment) per surgeon discretion based on bleeding risk.

- Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situation (within time frame) that would limit compliance with study requirements.
