The study is designed for patients with non small cell lung cancer whose cancer is too advanced and therefore cannot be operated with the goal of completely removing the cancer. At this stage of the disease, most patients cannot be cured from the disease, however, treatment can help to live longer and better by keeping the cancer under control. For that purpose, patients traditionally receive radiation therapy or chemotherapy or both treatments in succession. Recently, the administration of both treatment methods given concurrently showed somewhat better results when compared to successive administration. In some studies the drug Taxotere together with radiation performed well in keeping the cancer better under control.
