Trial summary

This study is to investigate, in a larger cohort of consecutive men, the proportion of abnormal MRI prostate in different phi ranges, and the cancer detected in Chinese men with abnormal MRI. This study aims to evaluate whether MRI prostate can be omitted in men with lower suspicion of prostate cancer. Read more about this study

About this study

Official title: The Performance of MRI Prostate in Men With Different Prostate Health Index (Phi) Values: Can we Save Some MRI Scans?

This study is to investigate, in a larger cohort of consecutive men, the proportion of abnormal MRI prostate in different phi ranges, and the cancer detected in Chinese men with abnormal MRI. This study aims to evaluate whether MRI prostate can be omitted in men with lower suspicion of prostate cancer.

Read the detailed description

This is a prospective cohort study recruiting consecutive men with elevated blood test PSA 4-10 ng/mL, normal prostate on digital rectal examination, and result for blood Prostate Health Index (phi) known. A multi-parametric MRI prostate with contrast will be performed in all subjects. MRI prostate will be reported according to PI-RADS (Prostate Imaging-Reporting and Data Systems) v2.1 recommendations[10] and scored from 1 to 5. A PI-RADS score of 3-5 is considered abnormal. The proportion of abnormal MRI in different phi ranges (primary outcome) will be compared.

The subjects will be offered a prostate biopsy according to usual clinical indications in our hospital: In men with phi >35 (higher risk of significant prostate cancer), prostate biopsy (systematic biopsy, plus MRI-guided if abnormal MRI) will be offered. In men with phi < 35 (lower risk of prostate cancer), prostate biopsy (systematic plus MRI-guided) will be offered only if MRI is abnormal.

What is being measured

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

  1. In men with higher risk of significant prostate cancer, proportion of men with abnormal MRI at different Prostate Health Index (phi) ranges

    In men with higher risk (phi>35) of significant prostate cancer), proportion of men with abnormal MRI.

    Measured: Baseline (only one-time point)

  2. In men with lower risk of significant prostate cancer, proportion of men with abnormal MRI at different Prostate Health Index (phi) ranges

    In men with lower risk (phi<35) of significant prostate cancer), proportion of men with abnormal MRI.

    Measured: Baseline (only one-time point)

Secondary outcomes (3)

  1. Sensitivity of various phi cutoffs to predict PI-RADS score ≥3 in MRI prostate

    Assessed by phi values and PI-RADS score in MRI prostate

    Measured: Baseline (only one-time point)

  2. Sensitivity of various phi cutoffs to predict PI-RADS score ≥4 in MRI prostate

    Assessed by phi values and PI-RADS score in MRI prostate

    Measured: Baseline (only one-time point)

  3. Proportion of low risk group diagnosis of clinically significant prostate cancer with abnormal MRI

    Diagnosis of clinically significant prostate cancer (Gleason 3+4 or above) in men with abnormal MRI and phi <35

    Measured: Baseline (only one-time point)

Questions about this trial

What is this clinical trial studying?

An observational study of Prostate Cancer, run by Chinese University of Hong Kong at 1 site in Hong Kong.

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 6 inclusion and 5 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: finished, as of the sponsor's last update on 5 Nov 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 Hong Kong. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

In men with higher risk of significant prostate cancer, proportion of men with abnormal MRI at different Prostate Health Index (phi) ranges (time frame: Baseline (only one-time point)). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT05438524, which also lists 18 linked publications.

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 5 Nov 2026.
