The standard treatment for non-small cell lung cancer, stage IV or IIIB malignant pleural effusion is chemotherapy. The decision to use a regimen is currently determined by toxicity or by physician's preference. In this protocol, the treatment regimen will be assigned based on the patients' tumor molecular profile. A tumor molecular profile analysis will allow the physician to define a specific molecular portrait that shows the genetic basis of the tumor. This analysis results in a detailed report that will determine which chemotherapy will be assigned to the patient.
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. 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. During treatment, a blood specimen will be obtained to check the patient's blood counts at the beginning and end of study, and prior to administration of every dose of chemotherapy. Approximately 3 teaspoonfuls (15 mls) of blood will be drawn each time.

Best Disease Response After a Maximum of Six Cycles.
Determine the number of participants for each category of response rates (RR) in newly diagnosed patients with advanced non-small cell lung cancer (NSCLC) who are treated with a chemotherapeutic regimen assigned to them on the basis of expression of the genes ribonucleotide reductase subunit 1 (ERCC1) and excision repair cross-complementing group 1 gene (RRM1) expression. Prior to treatment we measured the level of ERCC1 and RRM1 expression in the patients tumor, on the basis of which the patient would be assigned a specific doublet chemotherapy.
Time frame: 24 Months
Overall Survival (OS)
Median Overall Survival of Participants. OS and Progression Free Survival (PFS) probabilities were estimated using the Kaplan-Meier method. For statistical purposes, it is important to note that this trial was not designed to compare outcomes among patients assigned to the different chemotherapies, but rather that molecular analysis directed individualized chemotherapy assignment is feasible and yields promising results in outcomes.
Time frame: 24 Months
Progression Free Survival (PFS)
PFS was recorded as the time elapsed from the date of first treatment to the date of first evidence for disease progression or death. OS and PFS probabilities were estimated using the Kaplan-Meier method. For statistical purposes, it is important to note that this trial was not designed to compare outcomes among patients assigned to the different chemotherapies, but rather that molecular analysis directed individualized chemotherapy assignment is feasible and yields promising results in outcomes.
