Prostate Cancer Clinical Trial
Multiparametric Magnetic Resonance Imaging of the Prostate to Assess Disease Progression and Genomics in Patients Undergoing Active Surveillance for Prostate Cancer
Active surveillance (AS) is a standard approach to treat low and intermediate risk prostate cancer. For AS, disease progression is monitored. AS uses biopsies, prostate specific antigen (PSA) blood tests, and other tools. Researchers want to see if multiparametric magnetic resonance imaging (mpMRI) can help improve AS.
To see if mpMRI can improve how people are monitored during AS.
Men age 18 and older who have been diagnosed with prostate cancer within the last 2 years.
Participants will undergo AS. Their PSA level will be checked once a year via blood test. They will have a digital rectal exam once a year.
Participants will have biopsies every 2-3 years. Needles will be put into different parts of the prostate. The needles are guided by ultrasound imaging.
Participants will also have targeted biopsies with mpMRI and MRI guided fusion (MRI-US fusion). MRI-US fusion combines previous MRI images with live ultrasound images. For MRIs, participants will lie on their stomach on the scanner table. A coil may be placed in the rectum.
Participants will have a physical exam and medical record review at least every 3 years. Their weight and vital signs will be checked. They will give data about their daily activities, side effects, and symptoms.
Every 2-3 years, participants will fill out surveys about their prostate health and quality of life.
Participants may give blood, urine, prostate secretion, and saliva samples. The samples will be used for research.
Participation will last for as long as the participant does not need actual treatment for his prostate cancer.
Active Surveillance (AS) is a standard approach in the treatment of low and intermediate risk prostate cancer which employs a strategy of monitoring the clinical progression of prostate cancer.
AS utilizes prostate biopsies, prostate specific antigen (PSA), and digital rectal examinations (DRE) as tools to determine clinical progression in prostate cance
This protocol aims to assess an additional tool, multiparametric magnetic resonance imaging (mpMRI) to actively visualize and monitor disease within the prostate in addition to standard instruments used to determine clinical progression of disease.
To determine the role of mpMRI in the selection and management of participants for AS by correlating imaging findings with pathological progression as determined on serial biopsies.
To determine the optimal interval of MR imaging in monitoring AS participants for evidence of progression by correlating sequential MRIs with biopsies with the goal to reduce unnecessary imaging.
To evaluate the relationship between mpMRI, prostate biopsy pathology results, and progression in AS participants to determine if prostate biopsies may be safely avoided based on the accuracy of imaging (sensitivity and specificity).
Men, 18 years and older with biopsy confirmed prostate cancer
Gleason Score which less than or equal to 3+4=7
Initial diagnosis of prostate cancer within 2 years of study entry
Capable of being consented to the protocol
Single arm, prospective, cohort study to correlate mpMRI with prostate biopsy pathology.
We plan to accrue 508 participants over the entire study period, assuming about a 10% dropout to allow adequate statistical review.
Participants will be monitored for clinical progression of their prostate cancer with PSA, DRE, mpMRI, and prostate biopsy (systematic and MRI lesion targeted) as follows:
Initial prostate cancer antigen (PSA) screening with an additional PSA screen every 12 months
Initial DRE screening with additional DRE to be performed every year that either prostate MRI or biopsy is performed
Initial mpMRI and prior to each biopsy (i.e., mandated at least every two years until year five, and then every three years thereafter)
Initial systematic 12-Core prostate biopsy and MRI guided fusion (MRI-US fusion) prostate biopsy of all suspicious lesions (i.e., targeted biopsy). Future biopsies, including 12-core systematic and targeted biopsy (to be performed in the same session) will then be mandated every two years until year five at which time biopsies will be performed every three years thereafter unless contraindicated.
mpMRI and biopsies may be performed earlier if clinically indicated and will revert back to previous mpMRI/biopsy schedule after.
Biopsy pathology results will be used as the standard for diagnosis of clinical progression.
Participants must have confirmed histopathological diagnosis of adenocarcinoma of the prostate within 2 years prior to study entry. Pathologic diagnosis must be confirmed by Laboratory of Pathology, NCI. If archival tissue is unavailable or insufficient for this purpose, a fresh biopsy will be collected.
Biopsy confirmed prostate cancer with Gleason less than or equal to 3+4=7 (primary pattern 3)
Clinical stage: cT1C or cT2A
Adult males, greater than or equal to 18 years old
NOTE: Children are excluded because prostate cancer is not common in pediatric populations. Women are not eligible because this disease occurs only in men.
Ability of subject to understand and the willingness to sign a written informed consent document All participants should have a consent signed that demonstrates an understanding of active surveillance and the decision to choose active surveillance for their prostate cancer.
Subjects must be co-enrolled to NCI protocol 16-C-0010 Care of the Prostate Cancer Patient and Prospective Procurement of Prostate Cancer Tissue
