Overview
Brief Summary
The purpose of this study is to find out how best to detect clinically significant lesions of prostate cancer by using micro-ultrasound technology (ExactVu) and by multiparametric magnetic-resonance imaging (mpMRI).
Detailed Description
This is a pilot clinical trial with 30 patients with either: 1) suspected prostate cancer (based on elevated PSA or abnormal digital rectal exam (DRE), or 2) known low-risk prostate cancer being managed with active surveillance. Enrolled patients will undergo MRI fusion biopsy and standard-template 12 core TRUS biopsy as the standard-of-care. Patients will also undergo micro-ultrasound evaluation and targeted biopsy if lesions are identified. Detection rates of clinically significant lesions by ExactVu and by MRI will be compared.
Investigators
Eligibility Criteria
Inclusion Criteria
- •Patients scheduled to undergo biopsy and with one of the following:
- •Men with suspicion of prostate cancer
- •Men on active surveillance
- •Age ≥18 \[30\]
- •Have available multiparametric prostate MRI
- •Able to provide written, informed consent
- •No significant medical illness which in the opinion of the Investigator would preclude entry to study procedures
- •Be willing and able to comply with scheduled visits
Exclusion Criteria
- •Previously confirmed prostate cancer diagnosis with Grade Group \>= 2
- •Unable to undergo prostate biopsy
- •Prostate MRI unable to be evaluated using the PI-RADS v2 criteria
- •Men with contraindication for MRI or a prostate biopsy
- •Prostate biopsy within 8 weeks prior to mpMRI.
- •Any history of prostate treatment
Outcomes
Primary Outcomes
Detection Rate
Time Frame: 2 years
To compare the detection rates of clinically significant prostate cancer lesions by ExactVu micro-ultrasound and by MRI-fusion
Feasibility of ExactVu
Time Frame: 2 years
To determine the feasibility of using ExactVu micro-ultrasounds to screen for prostate cancer in socioeconomically disadvantaged populations with limited access to care. Feasibility is measured by the percentage of patients that successfully undergo the study procedures.
