If you will receive a standard radiation therapy for prostate cancer, the position of your prostate is determined by CT scan before start of the treatment. The position of the prostate during the treatment will be estimated daily using skin tattoos and weekly using a set of x-rays of your pelvic bones.
New equipment is now available that allows one to quickly image a patient while he is on the treatment machine and potentially use this to guide the treatment. This is known as image guided radiotherapy (IGRT). One way to use this new equipment is to place markers in the prostate prior to planning. The markers will then be present and visible on the planning images as well as the images taken on the treatment machine. In this study, you will undergo daily image-guidance, in addition to standard set-up via tattoos. The location of these markers can then be compared and adjustments in patient position can be made as discussed above. This may allow for better visualization the prostate during radiotherapy, which may provide more effective treatment.
To qualify for this study, patients must meet certain criteria, including but not limited to:
All patients receiving external beam intensity modulated radiotherapy for prostate cancer are eligible. Patients are not eligible if they have a hip prosthesis or are on anticoagulation (blood thinners) medication and cannot discontinue it.
