Conditions

Prostate Cancer

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.

Interventions

Patients will be evaluated with multiparametric MRI prostate followed by ExactVu micro-ultrasound to identify target lesions all of which will be biopsied by the examiner

Age
18 Years to 99 Years

Inclusion criteria

1. Patients scheduled to undergo biopsy and with one of the following: * Men with suspicion of prostate cancer * Men on active surveillance 2. Age ≥18 \[30\] 3. Have available multiparametric prostate MRI 4. Able to provide written, informed consent 5. No significant medical illness which in the opinion of the Investigator would preclude entry to study procedures 6. Be willing and able to comply with scheduled visits

Exclusion criteria

Men with contraindication for MRI or a prostate biopsy 5. Prostate biopsy within 8 weeks prior to mpMRI. 6. Any history of prostate treatment

Design outcomes

Primary

MeasureTime frameDescription
Detection Rate2 yearsTo compare the detection rates of clinically significant prostate cancer lesions by ExactVu micro-ultrasound and by MRI-fusion
Feasibility of ExactVu2 yearsTo 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.

Secondary

MeasureTime frameDescription
Predictive Performance Measures2 yearsTo evaluate the sensitivity of ExactVu micro-ultrasound method and MRI-fusion method in detection of prostate cancer
