The purpose of this study is to establish a listing (database) of patients diagnosed with lung cancer and treated with best supportive care and standard and investigational chemotherapy regimens, surgery, and radiation therapy at the UNM CRTC and other NMCCA sites. The information will be used to determine the results of various treatments for lung cancer subjects and to find where improvements can be made in safety, effectiveness, supportive care, treatment that eases tumors without curing them, treatments that cure tumors, prevention, and follow-up efforts. The database information will be compared to clinical trial data published in peer-reviewed journals and SEER outcome data. Patients will be acquired both before and after they are treated for lung cancer.
