Chemotherapy will consist of the assigned two drugs. Chemotherapy will be repeated every three or four weeks for at least two times. Patients will then have a CT scan to measure their tumor's response. Response can be reduction of tumor size, no change of tumor size, or increased tumor size. Doing CT Scans or other tests after every two cycles of chemotherapy will assess for response. If we see a favorable response we will continue chemotherapy for a maximum of two times after the best response we can see in the patient's tumor. If the patient's tumor grows larger, then we discontinue the study and the patient will discuss other treatment options with their doctor.
