During the study, you will have blood tests (about 2 teaspoons) every 3 weeks to look at your blood counts. These samples will be used only for routine lab tests. You will be seen by a physician every 3 weeks and given a physical exam. Your blood pressure will be monitored, and you will be asked about any side effects you are experiencing. A performance status evaluation will also be done. In addition, you will have a urine test every 2 cycles of treatment.
