Every 3 weeks (each cycle), you will have a physical exam, including measurement of vital signs (temperature, pulse, breathing rate, and blood pressure) and weight. Blood (about 3-4 teaspoons) will be collected for routine tests. A performance status evaluation (a test looking at the ability to perform everyday activities) and a liver function test will also be done. Your tumor will be evaluated by CT scan and chest x-ray every 2 cycles of study treatment.
