Routine blood tests (about 1 teaspoon) will be done weekly during treatment and before each course of therapy (every 3 weeks). A complete checkup, including a history and physical exam, pelvic exam, and routine blood tests (about 2-3 teaspoons) will also be done before each course of therapy and a month after treatment ends. CT or MRI scans will be repeated every 2 to 3 cycles and at the end of treatment. Participants who have a partial or complete response (the tumor shrinks by more than 50% or disappears completely) will have the CT or MRI repeated at least 4 weeks later to confirm the response.
