ABSTRACT
Accurate lymph node staging of lung cancer is crucial in determining optimal treatment plans and predicting patient outcome. Currently used lymph node maps have been reconciled to the internationally accepted International Association for the Study of Lung Cancer (IASLC) map published in the seventh edition of TNM classification system of malignant tumours. This article provides computed tomographic illustrations of the IASLC nodal map, to facilitate its application in day-to-day clinical practice in order to increase the appropriate classification in lung cancer staging.

Station 10. (A) The border between station 4R and 10R is the lower rim of the azygos vein (red dashed arrow). The border between station 4L and 10L is the upper rim of the left main pulmonary artery (red line). (B) Station 4R and 4L nodes at the level of azygos vein. Note the border between station 4R and 4L is the left lateral wall of the trachea (yellow line). (C) Stations 10R and 10L below the azygos vein. The pleural reflection (pink arrowhead) no longer serves as the border between station 4 and 10. The border between station 10R and 10L is the midline of tracheal bifurcation (yellow line). AoA: aortic arch; AZ: azygos vein; PA: left pulmonary artery.

Figure 10: Station 10. (A) The border between station 4R and 10R is the lower rim of the azygos vein (red dashed arrow). The border between station 4L and 10L is the upper rim of the left main pulmonary artery (red line). (B) Station 4R and 4L nodes at the level of azygos vein. Note the border between station 4R and 4L is the left lateral wall of the trachea (yellow line). (C) Stations 10R and 10L below the azygos vein. The pleural reflection (pink arrowhead) no longer serves as the border between station 4 and 10. The border between station 10R and 10L is the midline of tracheal bifurcation (yellow line). AoA: aortic arch; AZ: azygos vein; PA: left pulmonary artery.

Mentions: Station 10 includes the nodes immediately adjacent to the mainstem bronchus and hilar vessels such as the proximal portions of the pulmonary veins and main pulmonary arteries. There is a change of the borders between station 4 and 10 with the pleural reflection no longer serving as the border between them (Figure 10)4. The lymph nodes around the both main bronchi within the mediastinum are considered as station 10; the nodes below the lower margin of the azygos vein as 10R, and the nodes below the upper rim of the left main pulmonary artery as 10L. Therefore, some tumors previously staged as N2 are now staged as N1. Pitson et al.16 and El-Sharief et al.17 discussed a potential ambiguity for lymph nodes at the level of the tracheal bifurcation below the level of the superior vena cava-azygos vein junction, and grouped lymph nodes anterior to the tracheal bifurcation with the lower paratracheal station17. However, Lee et al.18 reported that the changed definition between N1 and N2 diseases by IASLC map works well in classifying patient prognosis.
