Before therapy starts, you will be asked to complete several questionnaires during a visit to the Radiation Oncology clinic at M. D. Anderson. These questionnaires measure physical and emotional symptoms. These questionnaires should take about 30 minutes to finish. Lung cancer patients will also complete some cognitive (mental) questionnaires. During this visit, the research nurse will teach you how to use the telephone system for measuring symptoms. You will tell the system the most convenient times for the telephone calls. The date of the call will be at the same or close to the date of your weekly clinic visit.
