About this study
The aim of this study was to compare the pain levels in transrectal ultrasound (TRUS)-guided standard 12-core prostate biopsy (SPB) and multiparametric prostate magnetic resonance imaging (MpMRI)-guided fusion prostate biopsy (FPB).
Read the detailed description
The study included patients that underwent prostate biopsy under local anesthesia (intrarectal 2% lidocaine gel + periprostatic nerve block) due to suspected prostate cancer. Patients detected with a Prostate Imaging Reporting and Data System score (PIRADS) ≥3 lesion on MpMRI underwent MpMRI-guided FPB (Group I) and the patients who had no suspected lesions or had a PI-RADS <3 lesion on MpMRI underwent TRUS-guided SPB (Group II). Pain assessment was performed using Visual Analog Scale (VAS) 5 min after the procedure. Following the procedure, the patients were asked to indicate the most painful biopsy step among the three steps (1: insertion of the probe into the rectum, 2: probe manipulation, 3: the piercing of the biopsy needle).

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Standard transrectal 12 core biopsyProcedure or surgery
Also called Group 2
TRUS-guided SPB was performed by obtaining 12 core samples in each patient. 6 cores from left and right. the cores labeled as, apex, mid, base, apex far lateral, mid far lateral and base far lateral
MRI- US fusion prostate biopsy (FPB)Procedure or surgery
Also called Group 1
FPB was performed by obtaining 10-12 core samples in each patient, followed by the acquisition of 2-4 core samples for each suspected lesion detected on MpMRI (combined biopsy)
| Study group | Role | What they receive |
|---|---|---|
| Group 1 | Experimental | In Group 1, Patients detected with a PI-RADS (Prostate Imaging Reporting and Data System) ≥3 lesion on MpMRI underwent MpMRI-guided MRI- US fusion prostate biopsy. In this fusion biopsy, 12 core standard biopsy and 2-4 cores of biopsies from lesions defined on multiparametric prostate MRI Receives: Procedure: MRI- US fusion prostate biopsy (FPB) |
| Group 2 | Active comparator | In Group 2, patients who had no suspected lesions or had a PI-RADS <3 lesion on MpMRI underwent Transrectal ultrasound guided 12 core prostate biopsy (SPB). Receives: Procedure: Standard transrectal 12 core biopsy |

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
The aim of this study was to compare the pain levels in transrectal ultrasound (TRUS)-guided standard 12-core prostate biopsy (SPB) and multiparametric prostate magnetic resonance imaging (MpMRI)-guided fusion prostate biopsy (FPB).
Detailed description
The study included patients that underwent prostate biopsy under local anesthesia (intrarectal 2% lidocaine gel + periprostatic nerve block) due to suspected prostate cancer. Patients detected with a Prostate Imaging Reporting and Data System score (PIRADS) ≥3 lesion on MpMRI underwent MpMRI-guided FPB (Group I) and the patients who had no suspected lesions or had a PI-RADS <3 lesion on MpMRI underwent TRUS-guided SPB (Group II). Pain assessment was performed using Visual Analog Scale (VAS) 5 min after the procedure. Following the procedure, the patients were asked to indicate the most painful biopsy step among the three steps (1: insertion of the probe into the rectum, 2: probe manipulation, 3: the piercing of the biopsy needle).

Questions about this trial
What is this clinical trial studying?
A study testing Standard transrectal 12 core biopsy and MRI- US fusion prostate biopsy (FPB) in people with Pain Due to Certain Specified Procedures and Prostate Cancer, run by TC Erciyes University at 1 site in Turkey (Türkiye).
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 4 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 1 Mar 2019. 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 Turkey (Türkiye). 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?
To detect painful steps of biopsy procedure by asking patients verbally (time frame: Within 5 minutes after biopsy). 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 NCT03859804, which also lists 23 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 1 Mar 2019.
