Use of Markers for the Detection and Treatment of Lung Cancer

The unacceptably high morbidity and mortality associated with the diagnosis of lung cancer mandates new approaches toward the early detection and treatment of this disease. Enhanced understanding of the molecular biology of the carcinogenic process is identifying many potential markers of risk of lung cancer occurrence as well as of poor prognosis. Identification of high risk populations who are at greatest risk of being diagnosed with and dying from lung cancer would allow delivery of more intensive screening and interventions to the individuals who are most likely to benefit from such strategies. This review examines the current status of markers of lung cancer risk, early detection, and prognosis, and their applicability to current standards of clinical care.
