Evaluation at study entry will include blood tests, computerized tomography (CT) scans or other types of scans needed to measure other disease sites. A biopsy of one tumor is required for tumor analysis. If the patient's cancer has spread to other locations that may be easier to obtain tissue from and be less invasive, then the biopsy specimen may be collected from one of several possible locations that may exist within the patient's body. These possible sites include lung, bone, liver, adrenal glands, lymph nodes, nodules under the skin, or in cases of brain involvement requiring surgery, brain tissue. Sometimes fluids build up between the lining of the lung and the lung itself. If this happened to the patient and their doctor tells them the fluid should be drained, then this fluid may also be a source of cells we can use to analyze the patients cancer. In very rare cases, other sites might be identified.
