2. Proportion of positive biopsy cores.
Background summary
Rationale:
Biopsies are taken systematically from the prostate without an imaging technique that allows us to visualize areas suspicious of cancer. Various studies conducted have shown that up to 35% of all clinically significant prostate cancers are not detected by systematic biopsy. In this study we will evaluate the potential of HistoScanningTM guided biopsy to increase the detection rate of prostate cancer.
Objective:
The primary objective of this study is to compare HistoScanningTM guided prostate biopsy with systematic biopsy in the detection of prostate cancer in men candidate for a first or second biopsy procedure.
Study design:
Observational pilot study.
Study population:
Men ≥ 40 years old with a clinical suspicion of prostate cancer and candidate for a bioptic procedure. The study population comprises both candidates for a first bioptic exam and candidates for a second bioptic procedure having a previous negative result independently from the present study.
Study procedure:
Patients will receive a HistoScanning prior to the biopsy procedure. In case one or more lesions of ≥ 0.2 cm3 are seen with HistoScanning a maximum of 4 HistoScanning guided prostate biopsy cores are taken in addition to the standard systematic prostate biopsies (8, 10 or 12 biopsies, dependent on prostate volume).
Main study parameters/endpoints:
Number of standard and HistoScanning guided cores, number of positive standard and HistoScanning guided cores, length of standard and HistoScanning guided core, % of standard and HistoScanning guided core infiltrated with cancer, Gleason score of standard and HistoScanning guided biopsies, prostate volume, baseline PSA, PSA density, results of digital rectal examination (DRE), TRUS and HistoScanning analysis.
Nature and extent of the burden and risks associated with participation, benefit and group relatedness:
The HistoScanning procedure should, from the patient’s perspective, be no different from standard diagnostic transrectal ultrasonography. The systematic and HistoScanning guided biopsy will be performed in the same session, so no extra visit is required. A maximum of 4 HistoScanning guided biopsy cores will be performed in addition to the standard systematic biopsy. Accordingly the number of bioptic cores taken in this study will not exceed 16.
Study objective
In this study we will evalute the potention of HistoScanning guided biopsy to increase the detection rate of prostate cancer.
Study design
There will be no follow-up. Patients visit the clinic once for the combined systematic and guided biopsy procedure.
Intervention
There will be no intervention. Patients undergo systematic and guided biopsies (invasive measurement).
