About this study
Official title: Phase II Evaluation of MR-Guided Laser Induced Interstitial Thermal Therapy (LITT) for Prostate Cancer
This phase II trial studies how well magnetic resonance (MR)-guided laser interstitial thermal therapy works in treating patients with prostate cancer. Laser therapy uses intense, narrow beams of light to cut and destroy tissue and may help treat prostate cancer
Read the detailed description
PRIMARY OBJECTIVES:
- To evaluate the oncologic efficacy of laster interstitial thermal therapy (LITT) with primary endpoint of undetectable cancer on magnetic resonance imaging (MRI)-guided biopsy of treatment zone at 3 months following treatment.
SECONDARY OBJECTIVES:
- To evaluate oncologic efficacy at 12 months following treatment based on biopsy of the treatment zone.
II. To determine treatment-related safety and toxicity. III. To longitudinally assess urinary and sexual function in the year following treatment.
OUTLINE:
Patients undergo MR-guided LITT.
After completion of study treatment, patients are followed up at 1, 3, and 12 months.
- Being tested
- Visualase Thermal Therapy, magnetic resonance imaging
- Medical subject headings
- Prostatic Neoplasms

What is being measured
The primary outcome is the main question the study is designed to answer.
Number of Participants With Undetectable Cancer on MRI-guided Biopsy of Ablation Zone Following Treatment
The primary study end point was the number of patients with no cancer on MRI guided biopsy of the ablation zone at 3 months.
Measured: At 3 months after ablation
Secondary outcomes (4)
The Number of Patients With Biopsy Cancer of the Treatment Zone
A systematic 12-core biopsy was performed at 1 year and the number of patients with biopsy cancer was counted.
Measured: At 12 months
The Total Number of Patients With Any Adverse Events Related to the Treatment
Treatment-related toxicity measured by the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) v4.0
Measured: 1,3, and 12 month after treatment and up to 12 months
Quality of Life in Terms of Urinary and Sexual Function in the Year Following Treatment Assessed Using the International Prostate Symptom Score (IPSS)
International Prostate Symptom Score (IPSS) measures urinary symptoms and continence and it ranged 0 to 35. Lower values are considered better outcome.
Measured: At 1,3 and 12 months
Quality of Life in Terms of Urinary and Sexual Function in the Year Following Treatment Assessed Using Sexual Health Inventory in Men (SHIM)
Sexual Health Inventory Score in Men (SHIM) measures sexual health and erectile function and it ranged 1 to 25. Lower values are considered better outcome.
Measured: At 1,3 and 12 months

Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 13 Mar 2018. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Yes. Results are posted in the registry (first posted 13 Mar 2018). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 13 Mar 2018; AzTrials last refreshed its copy on 6 Nov 2026.
