Thirty-ﬁve patients with 91 mediastinal lymph nodes underwent DWMRI. Lymph nodes were deﬁned on the MRI. Lymph node location according to UICC were as follows: 25 upper paratracheal, 34 lower paratracheal, 25 subcarinal, 3 hilar, 2 prevertebral, and 2 paraortic. Lymph node dimensions were between 0.8 cm and 3 cm (median dimension 1.3 cm). Jun 30, 2015 · Accurate lymph node staging of lung cancer is crucial in determining optimal treatment plans and predicting patient outcome.

The accurate assessment of lymph node involvement is recognized as a pivotal component of the staging and treatment of lung cancers. For approximately the past 40 years, lymph node “maps” have been used to describe the clinical and pathologic extent of lymph node metastases in lung cancer patients by labeling regions of intrathoracic nodes using a system of anatomic descriptors and ... Mediastinal lymph nodes are commonly encountered during EUS for nonthoracic indications. The most common EUS feature of these benign lymph nodes is a triangular or crescent shape, with possibly an echogenic center (Fig. 9.1).

This atlas was based on the prior map and has therefore been superseded by the new IASLC lymph node map. This paper aims to create a computed tomographic (CT) atlas based on the new IASLC lymph ... In the IASLC lung cancer node map proposal, 14 the workgroup notably identified that lymph node drainage in the superior mediastinum converges over the right paratracheal area and extends across the midline toward the left. Appropriately, the demarcation between right and left in terms of levels 2 and 4 needed not lie over the midline trachea ... May 11, 2017 · The lymph node map devised for thymic epithelial neoplasms defines anterior and deep regions based on boundaries that outline the peripheral extent of surgical dissection in all planes.

Apr 08, 2013 · Endobronchial ultrasound (EBUS) guided fine needle aspiration biopsy of mediastinal nodes offers a less invasive alternative for histologic sampling of the mediastinal nodes. The procedure has been widely adopted by pulmonologists and is poised to replace mediastinoscopy in the future. The lymph node map by Naruke et al, and its revisions, are often used for the description of the N factor of the TNM classification. 1,2 Mediastinal lymph node staging can be divided into imaging and sampling.
For example, with respect to "level VII," radiologists may apply this label to superior mediastinal nodes 2, radiation oncologists may apply this label to "prevertebral nodes" 3, and head and neck surgeons omit this level from their nomenclature altogether 1. Thus, it is best to name lymph node groups outside of the established levels I-VI.
