An observational study of Prostate Cancer, run by Advanced Medical Diagnostics s.a. at 7 sites in 5 countries.
Trial summary
Study design: -The study will be a phase I like study to assess the extent to which prostate HistoScanning (PHS, the index test) can identify and characterize foci of prostate cancer when compared to histological samples harvested during radical prostatectomy (the reference test).

About this study
Study design:
-The study will be a phase I like study to assess the extent to which prostate HistoScanning (PHS, the index test) can identify and characterize foci of prostate cancer when compared to histological samples harvested during radical prostatectomy (the reference test). The study will comprise 3 steps: first, defining the most suitable method for matching the TRUS (TransRectalUltrasonography) to histology (step 1); second, refining the algorithms (training set); third, verification of the PHS performances (test set).

Study objectives:
- Primary Objective:
- To evaluate the extent to which PHS can discriminate between malignant lesions of the prostate versus non-malignant tissue in 3D RF TRUS data using radical prostatectomy histological step sectioning as the reference test.
- Secondary Objectives:
- To adapt and refine PHS tissue characterisation algorithms using RF data that were previously developed using grey-level data as input.
- To assess the accuracy of PHS in predicting the volume of prostate cancers determined by histology.
- To assess the ability of PHS to rule in or rule out the presence of cancer > or = 0.5 cc and of > or = 0.2 cc as determined by histology.
- To evaluate the ability to discriminate primary Gleason pattern 4 and 5 versus 3 or less in tumours > or = 0.5 cc and > or = 0.2 cc.
- To assess the ability of PHS to correctly risk stratify patients.

Questions about this trial
What is this clinical trial studying?
An observational study of Prostate Cancer, run by Advanced Medical Diagnostics s.a. at 7 sites in 5 countries.
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 7 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: finished, as of the sponsor's last update on 29 Oct 2012. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 7 sites in Belgium, United Kingdom, Czechia, Germany, Hungary. 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.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT01191931, which also lists 6 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 29 Oct 2012; AzTrials last refreshed its copy on 6 Nov 2026.
