Important picture: Partitioning of mediastinal lymph nodes

IASLC lymph node map 2009

IASLC map(1)

Group 1 lymph nodes (supraclavicular, supraclavicular, and sternal notch nodes) are lymph nodes with incisions in the lower neck, supraclavicle, and sternum

IASLC map(2)

Group 2 lymph nodes (upper paratracheal lymph nodes

The amorphous plane at the left edge of the trachea can distinguish between left and right group 2 lymph nodes

IASLC map(3)

Group 3 lymph nodes are divided into anterior anterior anterior anvascular lymph nodes (3A, pre-vascular) and posterior posterior tracheal lymph nodes (3p pre-trotracheal

IASLC map(4)

Lymph nodes in group 4 (lower paratracheal) are similar to those in group 2, also located around the trachea, but on the caudal side

IASLC map(5、6)

Lymph nodes in groups 5 and 6 (subarctate lymph nodes in the aortic artery, subaortic; Group 6 aortic para-lymph nodes, para-aortic) EBUS-TBNA can not be detected

IASLC map(7)

Group 7 lymph nodes (subcarinal) are located at the end of the tracheal rumble and are not associated

IASLC map(8)

Group 8 lymph nodes (paraesophageal) are located below the sub-rumped lymph nodes and extend to the diaphragm

​

PET images showing increased FDG uptake of lymph nodes, while the same cross-section CT did not show enlarged lymph nodes (blue arrows), the likelihood of cancer metastasis of this lymph node is high, and PET testing is more specific than for non-enlarged lymph nodes

IASLC map(9) Group 9 lymph nodes (Pulmonary Ligament) are located within the pulmonary ligaments, including the posterior wall and lymph nodes in the lower part of the lower pulmonary vein

IASLC map(10) Group 10 lymph nodes (hilar) proximal lobe lymph nodes, including all main bronchi and paralar hilar lymph nodes

IASLC map (11-14) Group 11, the interlobey lymph nodes (11, interlobar), are located at the

Group 12 lymph nodes (12, lobar) are located at the site of leaf bronchial origin

Traditional mediastinoscopy: the following groups of lymph nodes can be biopsyed with cervical mediastinoscopy: upper paratracheal lymph nodes (2L, 2R), inferior paratracheal lymph nodes (4L, 4R), subadalon lymph nodes (7

Dilated mediastinoscopy: tumors of the upper lobe of the left lung may metastasize to the subortic lymph nodes (5) and paraortic lymph nodes (6

EUS-FNA: esophageal ultrasound endoscopic fine needle aspiration can be used to evaluate
all mediastinal lymph nodes.
In addition to assessing the left adrenal gland and left lobe of the liver, EUS can also evaluate lymph nodes in the lower mediastinal region (7, 8, 9
).
