Trial summary

This clinical trial studies whether transperineal micro-ultrasound can be used to detect prostate cancer during biopsy. Transrectal ultrasound is often used during prostate biopsy. Transrectal ultrasound imaging is a procedure in which a probe that sends out high-energy sound waves is inserted into the rectum. Read more about this study

About this study

Official title: Investigating the Feasibility of Using Transperineal Micro-Ultrasound to Detect Clinically Significant Prostate Cancer

This clinical trial studies whether transperineal micro-ultrasound can be used to detect prostate cancer during biopsy. Transrectal ultrasound is often used during prostate biopsy. Transrectal ultrasound imaging is a procedure in which a probe that sends out high-energy sound waves is inserted into the rectum. The sound waves are bounced off internal tissues or organs and make echoes. The echoes form a picture of body tissue called a sonogram. Transrectal ultrasound is used to look for abnormalities in the rectum and nearby structures, including the prostate. The images are used to guide the prostate biopsy. Transperineal micro-ultrasound is completed by placing a probe over the skin between the scrotum and anus (perineum). It is a high-resolution ultrasound at 29 megahertz (MHz) (compared to traditional ultrasound at 6-9 MHz). This higher frequency allows for an improved spatial resolution. This improved spatial resolution is approximately the diameter of a prostatic duct, and therefore, may be able to visualize slight changes in the structure of prostatic ducts that are not possible with standard transrectal ultrasound. Transperineal micro-ultrasound may be more effective in detecting prostate cancer during biopsy.

Read the detailed description

PRIMARY OBJECTIVES:

  1. To investigate the feasibility and validity of using transperineal micro-ultrasound to image the prostate and detect clinically significant prostate cancer.

II. To test the quality of visualization of the prostate gland using micro-ultrasound via the transperineal approach.

SECONDARY OBJECTIVE:

  1. To compare micro-ultrasound images done via the transperineal method to micro-ultrasound images done via the transrectal method to see if transperineal ultrasound has similar ability to detect suspicious prostate lesions as transrectal micro-ultrasound.

OUTLINE:

Patients undergo transperineal micro-ultrasound imaging over 3 minutes followed by transrectal micro-ultrasound imaging during standard of care prostate biopsy. Patients also undergo magnetic resonance imaging (MRI) during screening.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Proportion of patients with Prostate Risk Identification Using Micro-Ultrasound (PRIMUS) score (Feasibility)

    At the first stage, 28 patients will be enrolled. If the procedure was successful in at least 18 patients, the procedure will be considered feasible, and the study will proceed to the next stage. If less than 18 successes were observed, the study team will determine whether to continue the trial based on the data collected.

    Measured: Up to 2 months

  2. Visualization of the prostate from base to apex with adequate image quality for PRIMUS scoring

    Will decide yes or no for whether the prostate can be assessed using transperineal micro ultrasound in order to evaluate for possible prostate cancer using the PRIMUS scoring system. This includes being able to visualize the prostate from base to apex with adequate image quality for PRIMUS scoring.

    Measured: Up to 2 months

  3. Visualization of the prostate from right and left lateral margins with adequate image quality for PRIMUS scoring

    Will decide yes or no for whether the prostate can be assessed using transperineal micro ultrasound in order to evaluate for possible prostate cancer using the PRIMUS scoring system. This includes being able to visualize the prostate from right and left lateral margins with adequate image quality for PRIMUS scoring.

    Measured: Up to 2 months

Secondary outcomes (3)
  1. Successful generation of PRIMUS score in transperineal and transrectal ultrasound images

    Will compare transrectal and transperineal micro-ultrasound assessment of PRIMUS score. This will be a yes/no comparison. Summary statistics in frequencies and relative frequencies will be provided.

    Measured: Up to 7 months

  2. Ability to visualize the whole prostate using transperineal micro-ultrasound

    This will be a yes/no comparison. Summary statistics in frequencies and relative frequencies will be provided.

    Measured: Up to 7 months

  3. Quality of images of transperineal ultrasound and transrectal ultrasound of the prostate

    The quality of images of transperineal ultrasound will be compared to transrectal ultrasound of the prostate. Summary statistics in frequencies and relative frequencies will be provided.

    Measured: Up to 7 months

Questions about this trial

What is this clinical trial studying?

A study testing Biopsy of Prostate, Magnetic Resonance Imaging and Micro-ultrasound Imaging in people with Prostate Carcinoma, run by Roswell Park Cancer Institute at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: withdrawn, as of the sponsor's last update on 29 Oct 2026. 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.
