About

The objective in this study is to determine if MRI-identified progression can decrease frequency or need for repeated prostate biopsy in men on active surveillance (AS).

Our hypothesis is that MRI alone is adequate to detect progression of prostate cancer in men on active surveillance (AS) after a MRI-US fusion prostate biopsy.

Full description

MRI Fusion prostate biopsy will transform Active Surveillance (AS) for men with low risk prostate cancer. Treatment for prostate cancer, usually surgical removal or radiation delivered to the whole prostate, is associated with significant morbidity including incontinence and impotence.

The goal of this and future research is to maximize the effectiveness of prostate imaging in order to minimize the morbidity of prostate biopsy and hence improve the quality of life of patients with prostate cancer. There are many applications to improved imaging of prostate cancer, but several the investigators are interested in include: improved risk stratification to limit unnecessary treatment while providing appropriate treatment to prevent progression; limiting the number of biopsies needed for diagnosis and/or decreasing the frequency of biopsies and hence decreasing biopsy-related morbidity; focal therapy for confirmed focal disease rather than treating the entire prostate in order to limit the significant morbidity associated with whole-gland treatment.

This is an investigator-initiated, multi-center, prospective observational phase II trial evaluating MRI to detect prostate cancer progression in patients with low risk prostate cancer on Active Surveillance. The two centers involved will be the Yale-New Haven Hospital Smilow Cancer Center (Yale) and the VA Connecticut Healthcare System (VACT). The Yale School of Medicine will serve as the central data-coordinating center for this study.

Inclusion criteria

• Age 30-80

• Diagnosed with Gleason 6 prostate cancer

• <cT3 prostate cancer
• Ability to receive an MRI with IV gadolinium contrast
• Life expectancy >10 years (by physician estimate)
• Understanding and willingness to provide consent
• English speaking

Exclusion criteria

• Received treatment for prostate cancer (hormone manipulation, surgery, radiation).
• Known metastatic disease
• High risk prostate cancer by Epstein Criteria

Men on Active Surveillance

Description:

This study will include men between age 30-80 with Gleason 6 prostate cancer, prostate specific antigen (PSA) \<20, clinical stage \<cT3, and a life expectancy of at least ten years. To be eligible, men must have undergone an MRI-USG fusion prostate biopsy for an elevated PSA or abnormal prostate examination that demonstrates Gleason 6 prostate cancer. If a man is already on active surveillance, the MRI-USG fusion biopsy may be negative or confirm Gleason 6 prostate cancer. Eligible men will be approached at their post fusion-biopsy visit to discuss the biopsy results and offered enrollment in the trial.
