Section: Possible Risks, Discomforts, and Inconveniences
Subsections: Risks Or Discomforts Of Participation

Treatments often have side effects. It is possible that you may experience some, all, or none of the side effects described below. It is also possible that this combination treatment may cause some side effects that we cannot anticipate. For that reason, you will be watched closely while you are receiving treatment for any signs of unexpected side effects. The risks and discomforts of this research protocol are related to the normally expected risks associated with external radiation therapy for prostate cancer, and those expected for the placement of needles into the prostate through the rectum.  
Biopsies can cause pain and bleeding. There is also a small risk (<0.5%) of developing an infection or complication requiring hospitalization although you will be receiving an antibiotic to prevent this. The tissue sample that we get from the biopsy will be used for experiments in the laboratory, and portions will be stored and used later. Tissue specimens collected in the course of this research project may be banked and used in the future to investigate new scientific questions related to this protocol. If there are any risks to you or your family associated with these scientific studies which are not covered in this consent form, your consent will be obtained before such studies are performed. You should ask your physician any questions that you have concerning this program. Local Anesthesia for the procedure is provided with Bupivacaine, which is a medicine that is used routinely for prostate biopsies and rarely causes adverse reactions. At much higher doses this drug can cause restlessness, anxiety, dizziness, hearing changes, blurred vision and tremors, convulsions, seizures, decreased cardiac output, heart block, low blood pressure, heart arrhythmias, and cardiac arrest. You will have a chance to discuss these risks with your doctor.  
MRI scans cannot be done on people who have a cardiac pacemaker, neural pacemaker, surgical metal clips in the brain or on blood vessels, cochlear implants, or foreign metal objects within the eye. At the time of your MRI, you will be asked about these things. When you are in the scanning machine, a feeling of claustrophobia may come over you, and there will be a repetitive thumping noise. Cool air will surround you, and the room is lit so you will not feel like you are in a cave or underground. It is important to remain still during the MRI scan. You may have some discomfort or feeling of heat from the tube placed in the rectum. If you are very claustrophobic in MRI scanners you may ask your physician for a mild sedative for the procedure. If you do this you must not drive a vehicle after the MRI. You can notify the MRI  
STUDY NUMBER: 05-C-0191 CONTINUATION: page 4 of 7 pages technologist of any discomfort you feel. The medicine that is used for the injection may rarely (1:2000) cause an allergic reaction such as hives, shortness of breath, or low blood pressure. The medical personnel in the MRI room are prepared to treat you for this kind of reaction. If you participate in carbogen breathing during the MRI scan, a tube will be placed in your mouth that contains high concentrations of oxygen, called carbogen, and a clamp will be placed over your nose. Because the oxygen-risk gas (carbogen) contains carbon dioxide some people may feel short of breath while they breathe it. They are actually getting much more oxygen than is usually present in room air. We will monitor the blood oxygen with "pulse oximetry," which is a small device that clips over your finger, to make sure you are getting enough oxygen. If you feel you cannot tolerate breathing the gas you can simply spit out the mouthpiece and begin breathing room air.  
The feeling of shortness of breath will stop in a few seconds. The MRI study will be stopped any time you request.  
Antibiotic therapy with Levofloxacin can cause nausea, diarrhea, vomiting, and abdominal pain. Bad taste in the mouth, restlessness, rash, sensitivity to sunlight and seizures are other possible side effects. If you are known to be allergic to this antibiotic or if you have a reaction to it, please let us know and a different one, such as Bactrim, will be prescribed.  
Blood drawing may include pain, swelling, or bruising at the needle puncture site. These are expected and temporary. In addition, there is a very small risk of fainting or of infection at the needle entry site.  
Fiducial Maker Placement can cause pain and bleeding. There is also a small risk of developing and infection although you will be receiving an antibiotic to prevent this.  
Radiation Therapy can cause tiredness, skin reddening, and inflammation. The most common side effects of radiation to the prostate are cystitis (an inflammation of the urine system or bladder) causing frequent, painful, or urgent urination, and proctitis (an inflammation of the rectum) causing diarrhea, painful bowel movements, bleeding or increased gas. These side effects can be treated with medications and comfort measures if they occur and usually resolve over time after the radiation therapy is finished.  
Long-term or chronic side effects from radiation for prostate cancer do not usually occur, but they may include: increased gas, frequent urination, difficulty urinating, impotence, and infertility. Less common long term side effects can include discomfort in the prostate area, bleeding from the rectum or bladder, leakage of urine or bowel movements. Rare or extremely rare long-term side effects can include swelling of the legs and genital organs, injury to the hips or other bones, or new tumors caused by radiation.  
The side effects listed above are the same as those for standard external beam radiation therapy for prostate cancer.  
However, because we will be using larger doses to parts of the prostate that actually have cancer, it is possible that the side effects listed here may occur more frequently or be worse than they would be with standard external beam therapy.

Section: Purpose of Research
Subsections: Description Of Research Study

You are being asked to take part in this study because you have cancer of the prostate and will be receiving radiation therapy. The purpose of this study is to deliver higher doses of radiation just to the areas of your prostate that have the cancer without increasing the damage to the normal tissues. To do this we will use an MRI scan (Magnetic Resonance Imaging) that can better detect and localize cancer within your prostate gland. We may also perform a special MRI scan, called Dynamic Contrast Enhanced MRI (DCE-MRI), a medicine is injected into your veins and the MRI can measure how the medicine flows through your prostate gland. These measurements can tell us about the blood vessels in your prostate gland, which can also provide information about the cancer. In this study, you will undergo a procedure where needle biopsies from different parts of your prostate gland will be obtained during the MRI.  
The biopsy results will then be compared with the measurements from the MRI. This information will tell us where in

STUDY NUMBER: 05-C-0191 CONTINUATION: page 2 of 7 pages the prostate gland your cancer is located. We will use this information to plan and deliver your radiation therapy. About 36 men will take part in this study. Before you can start this procedure, we will do an evaluation to see if you are eligible to participate in this study. This will include a physical examination and blood laboratory studies. The day before the procedure you will take an antibiotic, called Levofloxacin. Some antacids or other drugs may interfere with this antibiotic; please discuss this with your doctor. The morning of the procedure, you will have another dose of antibiotic and a small enema. We will place a needle in a vein in your arm to inject the MRI medicine. The doctor will give you some local anesthetic into the area around the prostate to numb the tissues in that area and decrease any discomfort from the procedure. This may be done just before, or at the beginning the MRI procedure before the biopsies are obtained from your prostate. You will be taken to the MRI scanner and an antenna shaped like a tube will be placed in your rectum. The antenna provides a channel to take needle biopsies and obtain better pictures of your prostate gland. During the procedure you will need to lie very still on your stomach while MRI images are taken. During the scan, you may be asked to breathe carbogen air through a tube placed in your mouth. Carbogen contains high concentrations of both oxygen and carbon dioxide compared to room air. The doctor will use these scans to decide where to take the biopsies. . The scans using carbogen, are optional scans and you may elect not to participate in these procedures. For each of the biopsies, a needle will be placed through your rectum into your prostate gland while you lie in the MRI. Once the needle is in place, a small biopsy will be taken through the needle.  
This procedure will be repeated until 4-10 biopsies are taken. You will be lying still on your stomach for approximately one hour, but the entire biopsy procedure may take approximately 2 hours. The equipment, including the endorectal coil, used is investigational and has been specially made for this procedure and has been tested for safety. We will also observe you for any problems you might be having and will ask you to report any symptoms.  
It is possible that up to four non-reactive gold markers may be placed in the prostate gland during this procedure.  
These markers are about 1mm in diameter and are left in place. The markers will help us target the radiation treatments better and also will help us know where the biopsies were taken from if the prostate is removed. When you are finished, you will be moved to a stretcher and transferred to a bed to recover. You will be able to get up in about 30 - 60 minutes and will be able to walk and urinate as your medication wears off. We will observe you for any problems you might have and you will be asked to report any symptoms. You will be able to go home the same day of the procedure, and may need Tylenol or Motrin if you have any pain. You will need to take another dose of antibiotic the day after the procedure. Some patients may choose to repeat this biopsy procedure in the MRI during or after their treatment for prostate cancer. This step will help us find out whether the MRI test is still helpful after treatment. Any repeat biopsies will only be performed for clinical reasons.  
Radiation therapy is usually given once a day, Monday through Friday, except for holidays. You will be lying on your back and each treatment takes about 10 minutes. You will then receive a 8 and half week course of standard external beam radiation therapy using a newer form of radiation delivery called "intensity modulated radiation therapy" (IMRT). The use of IMRT will allow your doctor to increase the dose of radiation just to the areas of the prostate that appear on MRI
and/or biopsy to have the cancer. During the course of this study the amount of radiation dose will be increased and it is possible that areas of your prostate may be receiving more radiation than usually given as a standard dose. We will be closely monitoring you for any side effects that may tell us if this is harming your normal tissues and you will be asked to  
STUDY NUMBER: 05-C-0191 CONTINUATION: page 3 of 7 pages report any bowel symptoms and to fill out a questionnaire. Each week of your radiation treatment, we will also take an xray to check the position of the prostate and fiducial markers.  
Once your radiation treatment is completed, you will return to the Radiation Oncology Clinic for follow-up visits after your radiation treatment at 2, 4 8, and 12 weeks and then at 6, 9, 12,18 and every 6 months for up to 36 months. At these times you will have a PSA blood test, a physical examination and will also be asked to report any bowel symptoms and to fill out a questionnaire. It is possible, but not guaranteed that you may be eligible for other protocols in the future. Your physician will discuss this with you.
