Systematic Random Biopsy or MRI-US Fusion Biopsy in Diagnosing Prostate Cancer in Patients With PSA Progression

2017-08-01 13:38:21 | BioPortfolio


This randomized phase II trial studies how well systematic random biopsy or magnetic resonance imaging (MRI)-ultrasound image (US) fusion biopsy work in diagnosing prostate cancer in patients with elevated prostate specific antigen. Systematic random biopsy and MRI-US fusion biopsy may work better in improving the accuracy of prostate cancer detection.



I. To compare the detection of clinically significant prostate cancer (CSPCa) in Arm 1 versus Arm 2.

II. To compare between African American (AA) and white men the probability of developing CSPCa within three years of initial biopsy at the start of the study.


I. To determine complications and patient morbidity associated with either systematic random prostate biopsy (SR-Bx) versus (vs) magnetic resonance imaging-ultrasound image fusion biopsy (MRUS-Bx) + SR-Bx.


I. To compare Gleason score between MRUS-Bx and radical prostatectomy (RP) specimen among men who elect RP (~110 in the randomized controlled trial [RCT]).

II. To assess within Arm 1 the detection of CSPCa three months after SR-Bx among men initially diagnosed with clinically insignificant prostate cancer (CinsPCa) or no cancer.

III. To identify among men invited to participate and those actually enrolled in the RCT: determinants of study participation.

IV. To identify among men invited to participate and those actually enrolled in the RCT: determinants of treatment decision (active surveillance [AS] vs radiation vs RP) including the diagnostic method.

OUTLINE: Patients are randomized into 1 of 2 arms.

ARM I: Patients undergo SR-Bx.

ARM II: Patients undergo MRI scans at least one day before prostate biopsy, three months after SR-Bx, and 12 months after initial MRI. Patients with no lesion present only undergo SR-Bx. Patients with a lesion present undergo MRUS-Bx followed by SR-Bx.

After completion of study, patients are followed up at 2-4 weeks, 3, 6, 9, and 12 months, and then periodically for up to 5 years.

Medical and Biotech [MESH] Definitions

The use of molecularly targeted imaging probes to localize and/or monitor biochemical and cellular processes via various imaging modalities that include RADIONUCLIDE IMAGING; ULTRASONOGRAPHY; MAGNETIC RESONANCE IMAGING; fluorescence imaging; and MICROSCOPY.

A technique applicable to the wide variety of substances which exhibit paramagnetism because of the magnetic moments of unpaired electrons. The spectra are useful for detection and identification, for determination of electron structure, for study of interactions between molecules, and for measurement of nuclear spins and moments. (From McGraw-Hill Encyclopedia of Science and Technology, 7th edition) Electron nuclear double resonance (ENDOR) spectroscopy is a variant of the technique which can give enhanced resolution. Electron spin resonance analysis can now be used in vivo, including imaging applications such as MAGNETIC RESONANCE IMAGING.

Spectroscopic method of measuring the magnetic moment of elementary particles such as atomic nuclei, protons or electrons. It is employed in clinical applications such as NMR Tomography (MAGNETIC RESONANCE IMAGING).

A type of MAGNETIC RESONANCE IMAGING that uses only one nuclear spin excitation per image and therefore can obtain images in a fraction of a second rather than the minutes required in traditional MRI techniques. It is used in a variety of medical and scientific applications.

The creation of a visual display of the inside of the entire body of a human or animal for the purposes of diagnostic evaluation. This is most commonly achieved by using MAGNETIC RESONANCE IMAGING; or POSITRON EMISSION TOMOGRAPHY.
