Prostate Cancer Clinical Trial

A Phase II, Prospective Study of MRI in the Reclassification of Men Considering Active Surveillance in Prostate Cancer

Summary

Some men newly diagnosed with prostate cancer do not require immediate treatment. Rather, they can be followed closely with regular physical exams, blood work and repeated biopsies of the prostate. If the prostate cancer is becoming more aggressive, curative treatment can be offered at that time. This strategy of delaying treatment until necessary is called active surveillance in prostate cancer.

Active surveillance is a way of monitoring prostate cancer which aims to avoid or delay unnecessary treatment in men with less aggressive cancer.

Prostate cancer can be slow growing and, for many men, the disease may never progress or cause any symptoms. In other words, many men with prostate cancer will never need any treatment. Treatments for prostate cancer may cause side effects which can affect your quality of life. By monitoring the cancer with regular tests, you can avoid or delay these side effects.

Active surveillance is generally suitable for men with low risk early stage prostate cancer that is contained within the prostate gland (localized prostate cancer).

If doctors had a better way of identifying who might be best suited for this approach, it would likely become more appealing for more men. In this study, the investigators are looking at how accurate a magnetic resonance imaging (MRI) scan is at identifying high-risk prostate cancer, which might make a man a poor candidate for active surveillance.

To do this, the investigators are collecting data from the MRI scan of men and comparing it to a trans-rectal biopsy performed following the scan. The results of this study will help inform doctors how accurate the MRI is in identifying men who should not be on active surveillance.

Full Description

Before the research starts (screening): After signing this consent form, you will be asked to undergo some screening tests or procedures to find out if you can be in the research study. Many of these tests and procedures are likely to be part of regular cancer care and may be done even if it turns out that you do not take part in the research study. If you have had some of these tests or procedures recently, they may or may not have to be repeated.

A medical history, which includes questions about your health, current medications, any allergies and evaluation for whether you can safely have an MRI and biopsy
Performance status, which evaluates how you are able to carry on with your usual activities.
Review of the initial diagnostic biopsy, which you had when you were diagnosed with prostate cancer.
Routine Blood Tests ( PSA is a protein that is produced by the prostate gland. The PSA test has been widely used to screen men for prostate cancer. It is also used to monitor men who have been diagnosed with prostate cancer to see if their cancer is responding to therapy)
Physical Exam
Health State Questionnaires
These questionnaires review: Your feelings about your cancer diagnosis, your satisfaction with the cancer care you received, your health and symptoms over the past four weeks, and your overall urinary function

If these tests show that you are eligible to participate in the research study, you will begin the study treatment. If you do not meet the eligibility criteria, you will not be able to participate in this research study.

After the screening procedures confirm that you are eligible to participate in the research study:

You will be scheduled for a MRI between 2 to 14 months after your initial biopsy, which showed prostate cancer, to assess the grade and extent of your prostate cancer since your initial diagnosis.
You will be scheduled for a repeat prostate biopsy 0-3 months after your MRI is reviewed.

Based on the findings from the MRI, this biopsy will be performed either in the urologist's office with an ultrasound (a medical imaging technique that uses high frequency sound waves and their echoes) or using anesthesia and an MRI to guide where the biopsy is taken within the prostate.

If the MRI does not show anything of concern, you will have another ultrasound-guided biopsy similar to the one you had when you were initially diagnosed with prostate cancer. In this procedure twelve biopsy samples are taken from the prostate. Each biopsy is about the length of a dime and as narrow as a toothpick.

If the MRI has findings which need further evaluation, you will have a guided biopsy. In this procedure, you will have twelve samples taken from the prostate similar to the biopsy you had when you were diagnosed with prostate cancer. Additionally, several biopsies will be taken of the area or areas of concern noted on the MRI. This procedure will require anesthesia, which may be general anesthesia or another type. You will meet with the study physician prior to the biopsy procedure. The type of anesthesia to be used will be decided by the study physician in discussion with you. When undergoing a study in the MRI system, you will lie motionless inside this device Occasionally the machine will produce a loud banging noise, as if it were being pounded from the outside with a hammer. Earplugs are available to reduce this sound level.

While you are in the magnet, under the anesthetic, the investigators will do the biopsy. To do this the investigators will use 2 ways to help us reach the correct part of your prostate, one is a robotic needle holder, which will show us where to put the needle, by lining up the correct place outside on the skin or rectal wall and the study physician will push in the needle with his/her hand. Second the investigators will use a model of the best location(s), taken from images. The biopsy is done with a needle put in through the skin, under your scrotum or through the rectal wall by the doctor.

The entire length of the procedure will be approximately 3 hours. The results of the procedure and biopsy will be communicated by your doctor as soon as they are available. The results will also be shared with the research co-investigators. This will be done by sharing the pathology results for each biopsy as matched with the location/place it came from in your gland. The study doctor will share the results of your biopsy with you at your end of study visit.

Medical Information The investigators will collect your medical information when you come to the Dana-Farber Cancer Institute and link this information to your specimens so that the investigators may better understand how these tests affect how participants do over time. It is important to note the following: all blood, tissue, and data collected from participants will be used for research only and when the research is performed on your samples, the investigators conducting this research will not have access to participant identification information, such as medical record numbers.

End of study visit:

You will have an end of study visit approximately 30 days after your final biopsy is performed. At this visit, the study staff will:

Review your current PSA lab values
Review the results of your biopsy and discuss options for future treatment.
Ask you to complete several "Health- State" questionnaires if you have not already done so
Review any side effects that you may have experienced as a result of your recent biopsy.
