文档介绍：Regional Lymph Node Classification for
Lung Cancer Staging*
Clifton F. Mountain, MD, FCCP; and Carolyn M. Dresler, MD, FCCP
mendations for classifying regional lymph node stations for lung cancer staging have been
adopted by the American mittee on Cancer () and the Union Internationale
Contre le Cancer. The objective was to unify the two systems that have been mon use for
the past 10 years; that is, the schema advocated by the , adapted from the work of Tsuguo
Naruke, and the schema advocated by the American Thoracic Society and the North American
Lung Cancer Study Group. Anatomic landmarks for 14 hilar, intrapulmonary, and mediastinal
lymph node stations are designated. This classification provides for consistent, reproducible,
lymph node mapping that patible with the international staging system for lung cancer. It
is applicable for clinical and surgical-pathologic staging. (CHEST 1997; 111:1718-23)
