Once you are off-study, you will have long term follow-up visits every 3-6 months for the first 30 months and then every year after that. These visits will continue for up to 4 years, or longer if your doctor thinks it is necessary. At these visits, you will have a CT or MRI scan of your abdomen and pelvis and a chest x-ray. Blood (about 1 teaspoons) will be drawn for routine testing.
