Background Transbronchial needle aspiration ( TBNA ), serving as a remarkably invaluable and minimally invasive technique, has been widely used for the diagnosis and staging of mediastinal adenopathy and masses. To date, the I nternational A ssociation for the S tudy of L ung C ancer ( IASLC ) and W ang's nodal map are two well‐documented intrathoracic lymph node guidelines for the TBNA procedure. Method We characterized IASLC's and Wang's map, and interpreted the correlation of the two maps station by station. Results The pivotal role of IASLC map is to determine N descriptor in the tumor node metastasis (TNM) staging system of lung cancer, whilst Wang's map is employed to facilitate the localization of biopsy sites for bronchoscopists during TBNA performance. Furthermore, stations 1, 3 and 5 in Wang’ map are equivalent to 4R station in IASLC’ system, while stations 4 and 6 in Wang's account for IASLC station 4L as N2 stations. In addition, Wang's stations 2, 8 and 10 are correlated with station 7 in IASLC's. Wang's stations 7 and 9 are responsible for station 11R in IASLC's map. Conclusion Given their unique benefits and limitations, and the practical links between the two maps, it appears reasonable to highlight the significance of their complementary utilization upon TBNA performance and lung cancer staging.
