Spots Global Cancer Trial Database for Computed Tomography Urography (CTU) vs Intravenous Urography (IVU) on Patients at Risk of Urothelial Tumors

Study Description

Brief Summary: The goal of this clinical research study is to use computed tomography urography (CTU) scans and intravenous urography (IVU) scans to check the status of urothelial cancer, in order to try to learn the level of effectiveness of possibly using CTU by itself in future patients.

Detailed Description: Background for the Study: Currently, IVU is used to detect urothelial tumors and then computed tomography (CT) scans are performed after that, to check the status of the disease. This is typically done every 3 months for the first 2 years after diagnosis, and then every 6 months for the next 2 years. Researchers want to learn if this current routine method of using 2 diagnostic procedures can be replaced with CTU alone, in future patients. CTU uses the same scanner machine as CT scans do. The difference between these 2 types of scans is that in addition to collecting the same type of images and information that CT scans do, CTU may also allow the doctor to look at the lining of the tubes that carry urine from the bladder. Looking at the lining of these tubes is something that IVU is used for, and researchers want to find out if CTU can also be used for this purpose. Study Procedures: If you are found to be eligible to take part in this study, you will have a CTU procedure performed at least a day before or after your routine IVU. If your doctor has ordered a CT of your abdomen and pelvis and IVU, the CTU will be performed instead of a routine CT scan of the abdomen and pelvis that would normally occur. If your doctor has ordered just a CTU, you will have an IVU as well. CTU Procedure: The CTU procedure is very similar to the standard CT of the abdomen/pelvis that you would otherwise receive along with an ITU. To prepare for the CTU, you will be asked to drink contrast solution (a type of dye) in order to allow the tumor(s) to be more easily seen and checked. You will be given about 30 ounces (3 3/4 cups) of contrast solution to drink at 30 minutes before the CTU and another 7 ½ ounces (about a cup) of contrast solution to drink while you are on the scanning table. You will also receive Lasix (furosemide) by injection. Furosemide is given to help the tubes in your kidney dilate (expand) to improve the quality of the images. For the CTU , you will lie flat on a CT scanner and will receive additional contrast solution by vein during the scan. While the scan is being performed, you will be asked to hold your breath several times, for about 15-20 seconds each time. The process of having the CTU performed should take about 10 minutes longer than a regular CT scan. If the images are not clear enough, all or part of the scanning process may need to be repeated (without repeating the contrast). IVU Procedure: Either before the CTU or after it, depending on the order in which you were assigned to receive these procedures, you will receive the IVU as part of your routine care. Length of Study Participation: After one set of IVU and CTU scans have been performed, your participation in this study will be over. At least 3 months after your scans are performed, your images will be reviewed a second time by 2 additional M. D. Anderson doctors (radiologists) to compare their findings with the original radiologist's findings. This is an investigational study. The routine way to check the status of urothelial cancer is to use IVU and CT scanning. It is considered experimental, however, to use CTU instead of routine CT scanning for checking the status of urothelial cancer. At this time, using CTU for this purpose is being done in research only. Up to 135 patients will take part in this study. All will be enrolled at MD Anderson.
