The International Association for the Study of Lung Cancer (IASLC) lymph node map;The IASLC lymph node map defines 14 different lymph node stations,which may be grouped into 7 zones.;7 zones;Supraclavicular Zone;Station 1R: Right Low Cervical, Supraclavicular,and Sternal Notch Lymph Nodes.—The upper border of station 1R is the lower margin of the cricoid cartilage. The lower border of station 1R is the clavicles bilaterally and, in the midline,the upper border of the manubrium. The midline of the trachea serves as the boundary between stations 1R and 1L.;Station 1L: Left Low Cervical, Supraclavicular,and Sternal Notch Lymph Nodes.—The upper border of station 1L is the lower margin of the cricoid cartilage. The lower border of station 1L is the clavicles bilaterally and, in the midline, the upper border of the manubrium. The midline of the trachea serves as the border between stations 1R and 1L.;Upper Zone;Station 2R: Right Upper Paratracheal Lymph Nodes.—The upper border of station 2R is the apex of the right lung and pleural space, and in the midline, the upper border of the manubrium.The lower border of station 2R is the intersection of the caudal margin of the innominate vein with the trachea. The left lateral wall of the trachea (not the midline) serves as the boundary between stations 2R and 2L.;Station 2L: Left Upper Paratracheal Lymph Nodes.—The upper border of station 2L is the apex of the left lung and pleural space, and in the midline, the upper border of the manubrium.The lower border of station 2L is the superior superior border of the aortic arch. The left lateral border of the trachea (not the midline) serves as the boundary between stations 2R and 2L.;Station 3A: Prevascular Nodes.—The upper border of station 3A is the apex of the chest.The lower border of station 3A is the level of the carina. The anterior border of station 3A is the posterior aspect of the sternum. The posterior border of station 3A is the anterior border of t
