CT Anatomy of Lymph Node Stations The anatomic descriptions of each lymph node station have been more precisely described to avoid any overlap in defini-tion between stations. In the IASLC map, the number of lymph node stations is the same as that of sixth edition.

SUV of individual lymph nodes were obtained from the radiology report. The lymph node with the highest SUV was reported and only lymph nodes with SUV greater than 2.5 were considered positive The lymph node stations were initially delineated by 1radiation oncologist using the Varian Eclipse planning system (Varian Medical Systems, Palo Alto, CA). All of the images were then reviewed by 3 further radiation oncologists and a diagnostic radiologist to establish a consensus for delineating the nodal stations using the IASLC recommendations Accurate lymph node staging of lung cancer is crucial in determining optimal treatment plans and predicting patient outcome.

The International Association for the Study of Lung Cancer (IASLC) lymph node map, including the proposed grouping of lymph node stations into zones for the purposes of prognostic analyses In this issue of CHEST (see page 1299), Lee and colleagues1 examine the validity of a mapping system for lymph nodes proposed by the International Association for the Study of Lung Cancer (IASLC). They conclude that the definitions for the anatomic location of lymph nodes in the IASLC map accurately predict disease-free survival in patients undergoing resection of non-small cell lung cancer Accurate assessment of nodal involvement is essential in the management of lung cancer. Recently, the International Association for the Study of Lung Cancer (IASLC) Lung Cancer Staging Project published a new lymph node map with the aim of creating an internationally agreed framework that would allow precise and uniform determination of lymph node status by centers around the globe.1 This new. lymph node map was proposed by the International Thymic.

Lymph nodes are found throughout the body. The names used in describing lymph nodes groups for the purpose of lung cancer staging may differ and are reviewed in Table 4.1 . IASLC lymph node map 2009. Precarinal lymph nodes are located in the precarinal area, which is within the chest cavity around the lungs As for the N category, 48% (N=105) of the responders used the ITMIG/IASLC thymic nodal map, and lymph node dissection (N1/N2) was performed in 50%/21% in thymomas and 66%/41% in thymic carcinomas The IASLC lymph node map was correlated with Wang's map. Results. A total of 182 lymph node stations were sampled using EBUS-TBNA. 96 were positive for nodal metastasis. A total of four cases of samples taken from station 2R showed malignant cells. From the 74 cases series using cTBNA 167 nodes were sampled in 222 passes Lymph-node stages were validated using the IASLC lymph node map . Lymph nodes were free of residual tumor (ypN0) in 50/117 (42.7%) cases. Ipsilateral hilar lymph nodes were involved (ypN1).

Thoracic Lymph Node Map offers physician and other healthcare professions a quick and well-designed tool to look up regional lymph nodes. The app groups together the lymph nodes and color-codes them differently so they can be easily distinguishable scanning through the different CT images IASLC recommends use of a standardized lymph node map that assigns nodes into specific supraclavicular, upper, aorticopulmonary, subcarinal, lower, hilar/interlobar, and peripheral zones . The analysis of the new database revealed that the current N classification provides consistent separation of prognostically distinct groups Finally, with the segmentation of those anatomical organs, we convert the text definitions of the International Association for the Study of Lung Cancer (IASLC) lymph node map into patient-specific color-coded CT image maps. Thus, a lymph node station is automatically assigned to each lymph node. We applied this system to CT scans of 86. The N component. In 2009, the IASLC proposed a new chart of the regional lymph nodes, grouped in zones and stations  that has to be considered carefully in the staging of lung cancer .A survey by E l-S herief et al. demonstrated that the use of older maps and the inconsistencies in interpretation and application of the definitions of the IASLC lymph node map may potentially lead to stage.

Lymph node dissection has not been routinely performed, and there is currently no node map defined for thymic malignancy.

Lymph node evaluation. N1 and N2 lymph nodes were defined according to the lymph node map published by the International Association for the Study of Lung Cancer (IASLC) in 2009 .An N1 node was classified into hilar/interlobar and peripheral zones, according to the anatomical location We performed bronchoscopy with transbronchial needle aspiration (TBNA) (using a histologic 19 G needle) in subcarinal station (station number 7 according to IASLC lymph node map) and in right interlobar station (station R11). Pathological tissue demonstrated the presence of non-caseating granulomas without necrosis (Figure 4) Mediastinal lymph node staging is critical for management of lung and thoracic cancers. Lymph node harvesting by Natural Orifice Transluminal Endoscopic Surgery (NOTES) has proved feasible to access the mediastinum with less surgical trauma in animal models. A mediastinal lymph node mapping model may allow access to those specific lymph node stations accepted and used by conventional methods Lymphadenopathy refers to nodes that are abnormal in either size, consistency or number. In 2009, a new lung cancer lymph node map was proposed by the International Association for the Study of Lung Cancer (IASLC) to reconcile the difference between the Naruke and the Mountain-Dresler-American Thoracic Society (ATS) maps and redefine the definitions of the anatomical boundaries of each. radiological anatomy of thoracic lymph nodes 1.
