A6701QIBA: Studying Repeated DCE-MRI and DWI in Patients Diagnosed With Prostate Cancer
Study Details
Study Description
Brief Summary
RATIONALE: Diagnostic procedures, such as dynamic contrast-enhanced magnetic resonance imaging or DCE-MRI and diffusion-weighted imaging or DWI, may provide images of prostate cancer or any cancer that remains after biopsy.
PURPOSE: This trial studies repeated DCE-MRI and DWI in patients diagnosed with prostate cancer.

Detailed Description
OBJECTIVES:
Primary
-
Determine the test-retest performance, assessed by the repeatability coefficient [RC] of Ktrans and gadolinium curve (IAUGC90bn) and measured by median pixel values of the whole prostate.
-
Determine the test-retest performance, assessed by the RC of diffusion-weighted imaging (DWI) metrics D(t) and measured by median pixel values of the whole prostate.
Secondary
-
Determine the test-retest performance, assessed by RC of Ktrans, IAUGC90bn, and D(t), and measured by median pixel values of the dominant prostate tumor.
-
Determine the effect of reader on the RC of dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) and DWI metrics for whole prostate and tumor nodule target lesion.
-
Determine whether T1-dependent or T1-independent methods for gadolinium quantification in DCE-MRI studies produce differing values for the RC for Ktrans and IAUGC90bn.
-
Explore the correlation between DCE-MRI and DWI metrics for both whole prostate and dominant tumor nodule as target lesions. (Exploratory)
-
Determine whether the "coffee break" approach toward test-retest analysis of quantitative DWI provides a reasonable estimate of the RC of D(t)of the whole prostate, using as the gold standard the RC of D(t) obtained between the two separate MRI visits. (Exploratory)
OUTLINE: This is a multicenter study. Patients are stratified according to MRI vendor used (Siemens vs GE vs Philips).
Patients receive gadolinium-based contrast IV and undergo DCE-MRI* and DWI 2 imaging at 2-14 days apart prior to treatment initiation. A central reader evaluation of the 2 successive scans is then conducted.
NOTE: *At the discretion of the participating sites, the initial MRI visit (MRI SCAN 1) may be supplemented with endorectal-coil imaging per institutional norms.

Outcome Measures
Primary Outcome Measures
- Repeatability assessment of DCE-MRI metrics Ktrans and blood-normalized initial area under the gadolinium curve (IAUGC90bn) and the DWI metric D(t) [2 to 14 Days]
The repeatability coefficient (RC) and its 95% confidence interval (CI) will be estimated for each metric [ ktrans, IAUGC90bn] using the method of Barnhart and Barboriak, 2009
Secondary Outcome Measures
- Test-retest performance, assessed by the RC of Ktrans, IAUGC90bn, and D(t), and measured by median pixel values of the prostate tumor [2 to 14 Days]
The repeatability coefficient (RC) and its 95% confidence interval (CI) will be estimated for each metric using the method of Barnhart and Barboriak, 2009
- Comparison between T1-dependent or T1-independent methods for gadolinium quantification produce differing values for the RC for Ktrans [2 to 14 Days]
The repeatability coefficient (RC) and its 95% confidence interval (CI) will be estimated for each metric ktrans] and each method [ independent and dependent] using the method of Barnhart and Barboriak, 2009
Eligibility Criteria
Criteria
DISEASE CHARACTERISTICS:
-
Diagnosis of prostate adenocarcinoma by transrectal ultrasound (TRUS)-guided biopsy between 28 to 90 days prior to enrollment
-
Minimal tumor burden as defined by at least one of the following criteria:
-
One single core with ≥ 50% cancer burden and ≥ 5 mm tumor length
-
Two or more cores in the same prostate region, each with ≥ 30% cancer burden
-
Three or more cores positive for prostate cancer (of any magnitude of cancer burden) in the same prostate region
-
Gleason score of 7 or higher cancer burden
-
Prostate-specific antigen (PSA) ≥ 10 ng/mL
PATIENT CHARACTERISTICS:
-
Able to tolerate magnetic resonance imaging (MRI) required by protocol, to be performed at an American College of Radiology Imaging Network (ACRIN)-qualified facility and scanner
-
Not suitable to undergo MRI or gadolinium-based contrast agent because of:
-
Severe claustrophobia not relieved by oral anxiolytics per institutional standard practice
-

-
Renal failure, as determined by glomerular filtration rate (GFR) < 30 mL/min based on a serum creatinine level obtained within 48 hours prior to enrollment
-
Weight greater than that allowable by the MRI table, per local institutional practice
PRIOR CONCURRENT THERAPY:
-
No anti-androgenic therapy within 30 days prior to enrollment
-
No prior external-beam radiotherapy, proton radiotherapy, or brachytherapy to the prostate
-
No prior hip replacement or other major pelvic surgery
